Postnatal women's experiences of management of depressive symptoms: a qualitative study

Background

Postnatal depression is a public health problem requiring intervention. To provide effective care, information is needed on the experiences of those with high levels of depressive symptoms who are offered and accept, or decline, psychological intervention postnatally.

Aim

To provide the first integrated in-depth exploration of postnatal women''s experiences of the identification and management of symptoms of depression and the offer and acceptance of postnatal care by health visitors taking part in the PoNDER trial.

Setting

General practice: primary care within the former Trent regional health authority, England.

Method

Thirty women with 6-week Edinburgh Postnatal Depression Scale (EPDS) scores ≥18 and probable depression completed semi-structured interviews. All women had taken part in the Post-Natal Depression Economic Evaluation and Randomised controlled (PoNDER) trial where intervention group health visitors received training in identification of depressive symptoms and provided psychologically informed sessions based on cognitive-behavioural therapy or person-centred counselling principles.

Results

When accepted, psychological sessions were experienced as positive, effective, and ‘ideal care’. Women approved of using the EPDS but did not understand the health visitor''s role in supporting women. Seeking help and accepting sessions depended on women''s perspectives of their health visitor as an individual.

Conclusion

Women''s experience of their health visitors providing psychological sessions to help with postnatal depressive symptoms is highly positive. Women will better accept support from health visitors if they recognise their role in postnatal depression and find them easy to relate to on personal matters. There is a case for specific enhancement of interpersonal skills in health visiting, or alternatively offering a choice of health visitors to women.     

Measuring depression severity in general practice: discriminatory performance of the PHQ-9, HADS-D, and BDI-II

Background

The UK Quality and Outcomes Framework (QOF) rewards practices for measuring symptom severity in patients with depression, but the endorsed scales have not been comprehensively validated for this purpose.

Aim

To assess the discriminatory performance of the QOF depression severity measures.

Design and setting

Psychometric assessment in nine Scottish general practices.

Method

Adult primary care patients diagnosed with depression were invited to participate. The HADS-D, PHQ-9, and BDI-II were assessed against the HRSD-17 interview. Discriminatory performance was determined relative to the HRSD-17 cut-offs for symptoms of at least moderate severity, as per criteria set by the American Psychiatric Association (APA) and NICE. Receiver operating characteristic curves were plotted and area under the curve (AUC), sensitivity, specificity, and likelihood ratios (LRs) calculated.

Results

A total of 267 were recruited per protocol, mean age = 49.8 years (standard deviation [SD] = 14.1), 70% female, mean HRSD-17=12.6 (SD = 7.62, range = 0–34). For APA criteria, AUCs were: HADS-D = 0.84; PHQ-9 = 0.90; and BDI-II = 0.86. Optimal sensitivity and specificity were reached where HADS-D ≥9 (74%, 76%); PHQ-9 ≥12 (77%, 79%), and BDI-II ≥23 (74%, 75%). For NICE criteria: HADS-D AUC = 0.89; PHQ-9 AUC = 0.93; and BDI-II AUC = 0.90. Optimal sensitivity and specificity were reached where HADS-D ≥10 (82%, 75%), PHQ-9 ≥15 (89%, 83%), and BDI-II ≥28 (83%, 80%). LRs did not provide evidence of sufficient accuracy for clinical use.

Conclusion

As selecting treatment according to depression severity is informed by an evidence base derived from trials using HRSD-17, and none of the measures tested aligned adequately with that tool, they are inappropriate for use.     

A Service-Based Evaluation of a Therapist-Supported Online Cognitive Behavioral Therapy Program for Depression

Background

Evidence suggests that Internet-delivered cognitive behavioral therapy (CBT) may be as effective as face-to-face delivery for depression, but attrition and engagement rates remain a challenge.

Objective

This service-based study aimed to evaluate an online, therapist-supported, CBT-based program for depression. The program was specifically designed to address engagement issues, most notably by integrating online therapist support and communication within the platform.

Methods

Participants were 80 adults who were registered university students. Participants used the modular online program over 8 weeks, supported by a therapist. Engagement information was gathered automatically by the online system, and analyzed for all participants. Severity of participants’ self-reported symptoms of depression were assessed preintervention and postintervention using the Beck Depression Inventory-II (BDI-II). Postintervention measures were completed by 53 participants.

Results

A high level of engagement was observed compared to a previous study within the same service, along with extensive use of a range of program features. A statistically significant (P<.001) decrease in self-reported depressive symptomatology from preintervention (mean BDI-II 25.47) to postintervention (mean BDI-II 15.53) with a large effect size (d=1.17) was also observed.

Conclusions

The results indicate the potential of unintrusive and easily provided online support to enhance engagement with online interventions. The system described in the paper also illustrates how such online support can be tightly integrated with interactive online programs by using a range of design strategies intended to improve the user experience.     

Screening older people with musculoskeletal pain for depressive symptoms in primary care

Background

Older patients presenting to GPs with musculoskeletal pain are at high risk of having concurrent depression.

Aim

To investigate the performance of ultra-short (1–4 items tools) screening questions used during the consultation, and through a patient questionnaire to detect depressive symptoms among older adults presenting with musculoskeletal pain to general practice.

Design of study

Cross-sectional survey, linked GP consultation data.

Setting

General practices in central Cheshire, UK.

Method

Consecutive patients aged ≥50 years presenting with non-inflammatory musculoskeletal pain were eligible to participate. GPs screened all patients in the consultation for the presence of depressive symptoms using two questions. All patients were sent a postal questionnaire within 1 week of consultation containing the Hospital Anxiety and Depression Scale and the written version of the depression screening questions.

Results

The total number of patients included in the study was 428. In total, 35.5% of consulters had comorbid depressive symptoms, with 13.5% experiencing moderate or severe symptoms. Just over half of participants (n = 218/242; 51.4%) screened positive on self-administered screening at home compared with only 78 (20.8%) on GP-administered screening in the consultation. There was little difference between GPadministered and self-administered screening in the probability of depressive symptoms among those who screened positive with regard to exhibiting signs of having depressive symptoms.

Conclusion

Older patients consulting their GP with musculoskeletal pain frequently have comorbid mental ill health. Ultrashort depression screening questions administered during the consultation miss a large number of those with depressive symptoms, including six out of eight patients with severe symptoms. An improvement in the performance of screening questions in this patient group or narrowing the definition of ‘high risk’ from all patients aged ≥50 years presenting with musculoskeletal pain could help to improve detection.     

Predictors of Response to Web-Based Cognitive Behavioral Therapy With High-Intensity Face-to-Face Therapist Guidance for Depression: A Bayesian Analysis

Background

Several studies have demonstrated the effect of guided Internet-based cognitive behavioral therapy (ICBT) for depression. However, ICBT is not suitable for all depressed patients and there is a considerable level of nonresponse. Research on predictors and moderators of outcome in ICBT is inconclusive.

Objective

This paper explored predictors of response to an intervention combining the Web-based program MoodGYM and face-to-face therapist guidance in a sample of primary care patients with mild to moderate depressive symptoms.

Methods

Participants (N=106) aged between 18 and 65 years were recruited from primary care and randomly allocated to a treatment condition or to a delayed treatment condition. The intervention included the Norwegian version of the MoodGYM program, face-to-face guidance from a psychologist, and reminder emails. In this paper, data from the treatment phase of the 2 groups was merged to increase the sample size (n=82). Outcome was improvement in depressive symptoms during treatment as assessed with the Beck Depression Inventory-II (BDI-II). Predictors included demographic variables, severity variables (eg, number of depressive episodes and pretreatment depression and anxiety severity), cognitive variables (eg, dysfunctional thinking), module completion, and treatment expectancy and motivation. Using Bayesian analysis, predictors of response were explored with a latent-class approach and by analyzing whether predictors affected the slope of response.

Results

A 2-class model distinguished well between responders (74%, 61/82) and nonresponders (26%, 21/82). Our results indicate that having had more depressive episodes, being married or cohabiting, and scoring higher on a measure of life satisfaction had high odds for positively affecting the probability of response. Higher levels of dysfunctional thinking had high odds for a negative effect on the probability of responding. Prediction of the slope of response yielded largely similar results. Bayes factors indicated substantial evidence that being married or cohabiting predicted a more positive treatment response. The effects of life satisfaction and number of depressive episodes were more uncertain. There was substantial evidence that several variables were unrelated to treatment response, including gender, age, and pretreatment symptoms of depression and anxiety.

Conclusions

Treatment response to ICBT with face-to-face guidance may be comparable across varying levels of depressive severity and irrespective of the presence and severity of comorbid anxiety. Being married or cohabiting, reporting higher life satisfaction, and having had more depressive episodes may predict a more favorable response, whereas higher levels of dysfunctional thinking may be a predictor of poorer response. More studies exploring predictors and moderators of Internet-based treatments are needed to inform for whom this treatment is most effective.

The Clinical Effectiveness of Web-Based Cognitive Behavioral Therapy With Face-to-Face Therapist Support for Depressed Primary Care Patients: Randomized Controlled Trial

Background

Most patients with mild to moderate depression receive treatment in primary care, but despite guideline recommendations, structured psychological interventions are infrequently delivered. Research supports the effectiveness of Internet-based treatment for depression; however, few trials have studied the effect of the MoodGYM program plus therapist support. The use of such interventions could improve the delivery of treatment in primary care.

Objective

To evaluate the effectiveness and acceptability of a guided Web-based intervention for mild to moderate depression, which could be suitable for implementation in general practice.

Methods

Participants (N=106) aged between 18 and 65 years were recruited from primary care and randomly allocated to a treatment condition comprising 6 weeks of therapist-assisted Web-based cognitive behavioral therapy (CBT), or to a 6-week delayed treatment condition. The intervention included the Norwegian version of the MoodGYM program, brief face-to-face support from a psychologist, and reminder emails. The primary outcome measure, depression symptoms, was measured by the Beck Depression Inventory-II (BDI-II). Secondary outcome measures included the Beck Anxiety Inventory (BAI), the Hospital Anxiety and Depression Scale (HADS), the Satisfaction with Life Scale (SWLS), and the EuroQol Group 5-Dimension Self-Report Questionnaire (EQ-5D). All outcomes were based on self-report and were assessed at baseline, postintervention, and at 6-month follow-up.

Results

Postintervention measures were completed by 37 (71%) and 47 (87%) of the 52 participants in the intervention and 54 participants in the delayed treatment group, respectively. Linear mixed-models analyses revealed a significant difference in time trends between the groups for the BDI-II, (P=.002), for HADS depression and anxiety subscales (P<.001 and P=.001, respectively), and for the SWLS (P<.001). No differential group effects were found for the BAI and the EQ-5D. In comparison to the control group, significantly more participants in the intervention group experienced recovery from depression as measured by the BDI-II. Of the 52 participants in the treatment program, 31 (60%) adhered to the program, and overall treatment satisfaction was high. The reduction of depression and anxiety symptoms was largely maintained at 6-month follow-up, and positive gains in life satisfaction were partly maintained.

Conclusions

The intervention combining MoodGYM and brief therapist support can be an effective treatment of depression in a sample of primary care patients. The intervention alleviates depressive symptoms and has a significant positive effect on anxiety symptoms and satisfaction with life. Moderate rates of nonadherence and predominately positive evaluations of the treatment also indicate the acceptability of the intervention. The intervention could potentially be used in a stepped-care approach, but remains to be tested in regular primary health care.

Systematic Review on Internet Support Groups (ISGs) and Depression (1): Do ISGs Reduce Depressive Symptoms?

Background

Internet support groups (ISGs) enable individuals with specific health problems to readily communicate online. Peer support has been postulated to improve mental health, including depression, through the provision of social support. Given the growing role of ISGs for both users with depression and those with a physical disorder, there is a need to evaluate the evidence concerning the efficacy of ISGs in reducing depressive symptoms.

Objective

The objective was to systematically review the available evidence concerning the effect of ISGs on depressive symptoms.

Method

Three databases (PubMed, PsycINFO, Cochrane) were searched using over 150 search terms extracted from relevant papers, abstracts, and a thesaurus. Papers were included if they (1) employed an online peer-to-peer support group, (2) incorporated a depression outcome, and (3) reported quantitative data. Studies included both stand-alone ISGs and those used in the context of a complex multi-component intervention. All trials were coded for quality.

Results

Thirty-one papers (involving 28 trials) satisfied the inclusion criteria from an initial pool of 12,692 abstracts. Sixteen trials used either a single-component intervention, a design in which non-ISG components were controlled, or a cross-sectional analysis, of which 10 (62.5%) reported a positive effect of the ISG on depressive symptoms. However, only two (20%) of these studies employed a control group. Only two studies investigated the efficacy of a depression ISG and neither employed a control group. Studies with lower design quality tended to be associated with more positive outcomes (P = .07). Overall, studies of breast cancer ISGs were more likely to report a reduction in depressive symptoms than studies of other ISG types (Fisher P = .02), but it is possible that this finding was due to confounding design factors rather than the nature of the ISG.

Conclusions

There is a paucity of high-quality evidence concerning the efficacy or effectiveness of ISGs for depression. There is an urgent need to conduct high-quality randomized controlled trials of the efficacy of depression ISGs to inform the practice of consumers, practitioners, policy makers, and other relevant users and providers of online support groups.     

Depression and conservative surgery for breast cancer

BACKGROUND:

Depression is prevalent among women and associated with reduced quality of life, and therefore it is important to determine its incidence in adult women, especially in those with breast cancer.

OBJECTIVE:

To determine the occurrence of depression in women who underwent conservative surgery for breast cancer with or without breast reconstruction.

METHODS:

Seventy‐five women aged between 18 and 65 years were enrolled. Patients had undergone conservative surgery for breast cancer with immediate breast reconstruction (n = 25) or without breast reconstruction (n = 25) at least one year before the study. The control group consisted of 25 women without cancer, but of similar age and educational level distribution as the other two groups. The Beck Depression Inventory was used to measure depression. The collected data were assessed using analysis of variance and the χ² test.

RESULTS:

There were no significant differences between groups in age (p = 0.72) or educational level (p = 0.20). A smaller number of patients had undergone the menopause (p = 0.02) in the control group than in other groups. There were no significant differences in occurrence of depression between groups (χ² = 9.97; p = 0.126).

CONCLUSION:

Conservative surgery for breast cancer did not affect the occurrence of depression in women, regardless of whether breast reconstruction was performed.     

The association of major depressive episode and personality traits in patients with fibromyalgia

INTRODUCTION:

Personality traits have been associated with primary depression. However, it is not known whether this association takes place in the case of depression comorbid with fibromyalgia.

OBJECTIVE:

The authors investigated the association between a current major depressive episode and temperament traits (e.g., harm avoidance).

METHOD:

A sample of 69 adult female patients with fibromyalgia was assessed with the Temperament and Character Inventory. Psychiatric diagnoses were assessed with the Mini-International Neuropsychiatric Interview severity of depressive symptomatology with the Beck Depression Inventory, and anxiety symptomatology with the IDATE-state and pain intensity with a visual analog scale.

RESULTS:

A current major depressive episode was diagnosed in 28 (40.5%) of the patients. They presented higher levels of harm avoidance and lower levels of cooperativeness and self-directedness compared with non-depressed patients, which is consistent with the Temperament and Character Inventory profile of subjects with primary depression. However, in contrast to previous results in primary depression, no association between a major depressive episode and self-transcendence was found.

CONCLUSIONS:

The results highlight specific features of depression in fibromyalgia subjects and may prove important for enhancing the diagnosis and prognosis of depression in fibromyalgia patients.     

A comparison of psychometric properties between internet and paper versions of two depression instruments (BDI-II and MADRS-S) administered to clinic patients

Background

Self-report measures can guide clinical decisions and are useful when evaluating treatment outcomes. However, many clinicians do not use self-report measures systematically in their clinical practice. Internet-based questionnaires could facilitate administration, but the psychometric properties of the online version of an instrument should be explored before implementation. The recommendation from the International Test Commission is to test the psychometric properties of each questionnaire separately.

Objective

Our objective was to compare the psychometric properties of paper-and-pencil versions and Internet versions of two questionnaires measuring depressive symptoms.

Methods

The 87 participating patients were recruited from primary care and psychiatric care within the public health care system in Sweden. Participants completed the Beck Depression Inventory (BDI-II) and the Montgomery-Åsberg Depression Rating Scale—Self-rated (MADRS-S), both on paper and on the Internet. The order was randomized to control for order effects. Symptom severity in the sample ranged from mild to severe depressive symptoms.

Results

Psychometric properties of the two administration formats were mostly equivalent. The internal consistency was similar for the Internet and paper versions, and significant correlations were found between the formats for both MADRS-S (r = .84) and the BDI-II (r = .89). Differences between paper and Internet total scores were not statistically significant for either questionnaire nor for the MADRS-S question dealing with suicidality (item 9) when analyzed separately. The score on the BDI-II question about suicidality (item 9) was significantly lower when administered via the Internet compared with the paper score, but the difference was small (effect size, Cohen’s [d] = 0.14). There were significant main effects for order of administration on both questionnaires and significant interaction effects between format and order. This should not, however, pose a problem in clinical use as long as the administration format is not changed when repeated measurements are made.

Conclusions

The MADRS-S can be transferred to online use without affecting the psychometric properties in a clinically meaningful way. The full BDI-II also seems to retain its properties when transferred; however, the item measuring suicidality in the Internet version needs further investigation since it was associated with a lower score in this study. The use of online questionnaires offers clinicians a more practical way of measuring depressive symptoms and has the potential to save resources.     

The pattern and challenges of infertility management in Lagos,Nigeria

Background

Infertility remains a threat to successful reproduction by couples desirous of pregnancy.

Objective

To determine the pattern of infertility cases amongst infertile couples seeking care in Lagos University Teaching Hospital as well as challenges in their management.

Methods

A review of the management of couples referred for infertility to the gynaecological outpatient clinic of the Lagos University Teaching Hospital (LUTH), Nigeria from 1^st January 2005 to 31^st December 2006.

Results

The incidence of infertility was found to be 26.8% of the gynaecological consultations with a mean duration of infertility of 4.3 ± 3.4 years. The mean age of the women was 33.8 ± 5.2 years and 66.1% were nulliparous. Secondary infertility accounted for 80% of cases. Male factors only was the cause in 11.1%, female factor only in 37.8%, both male and female factors in 40% while no cause was identifiable in 11.1%. There was no association between tubal occlusion and a history of induced abortion in this study (p >0.05). There was a high rate of discontinuation of care by their large numbers lost to follow up.

Conclusion

Infertility is still a public health problem in Lagos, Nigeria.     

Metastatic breast cancer in a Nigerian tertiary hospital

Background

Late presentation of breast carcinoma is common in resource-limited countries with attendant poor outcome.

Objective

To describe the pattern of clinical presentation and challenges of treating patients presenting with metastatic breast carcinoma in a Nigerian hospital.

Method

Clinical records of all patients who presented with metastatic breast carcinoma between January 1991 and December 2005 at the Obafemi Awolowo University Teaching Hospitals Complex, Ile-Ife, Nigeria were reviewed.

Results

More than half of all histologically confirmed breast cancer patients seen within the study period presented with metastatic disease. Their ages ranged between 20–81years with a mean age of 45.9 years. Only 3% (6 of 202) were males. Two-thirds had more than one secondary site on initial evaluation and the commonest sites were liver (63%), lung parenchyma (51%), pleura (26%) and contralateral breast in 25%. On immunohistochemistry, basal like tumours were found in 46.1%. Mastectomy was done in 37 patients with fungating breast masses while only one third of those referred to a nearby center for radiotherapy had it done. One year survival rate was 27%.

Conclusion

Metastatic disease is common in Nigeria and treatment is limited due to resource limitations. Improved awareness of the disease is advocated to reduce late presentation.     

Patients' views of physical activity as treatment for depression: a qualitative study

Background

Clinical guidance recommends physical activity to manage patients with persistent subthreshold depressive symptoms or mild-to-moderate depression. However, little is known regarding the acceptability of physical activity as a treatment for depression from patients'' perspective.

Aim

To explore patients'' views of physical activity for the treatment of depression in the context of primary care.

Design of study

In-depth interviews were held with 33 participants taking part in a randomised controlled trial assessing the effectiveness of physical activity for the management of depression.

Setting

Primary care.

Results

Most participants perceived physical activity to be an acceptable treatment for depression. The mechanisms by which physical activity could enhance mood were attributed to a number of subjective benefits including biochemical pathways, providing a source of distraction from negative thoughts, and a sense of purpose. Participants who expressed a belief that their depression was caused by biochemical mechanisms reported activity that ‘raised the heartbeat’ as most beneficial, while those who believed depression was situational in origin tended to state the benefits of less-aerobic activities, such as walking. Many participants reported low motivation and a lack of confidence as barriers to undertaking physical activity. These patients suggested that medication could be helpful for initiating and maintaining activity.

Conclusion

Patients view physical activity as an effective treatment for depression. However, they vary in their views about how physical activity might impact on depression, what intensity and form of activity is necessary to enhance mood, and the barriers to undertaking activity. This variation suggests the need for GPs to elicit patients'' views on physical activity as a treatment, and offer interventions that are tailored to the needs and expectations of individual patients.     

Cost-utility and cost-effectiveness of internet-based treatment for adults with depressive symptoms: randomized trial

Background

The effectiveness of Internet-based treatments for depression has been demonstrated; their cost-effectiveness, however, has been less well researched.

Objective

Evaluating the relative cost-utility and cost-effectiveness of (1) Internet-based cognitive behavioral therapy, (2) Internet-based problem-solving therapy, and (3) a waiting list for adults with depressive symptoms.

Methods

A total of 263 participants with clinically significant depressive symptoms were randomized to Internet-based cognitive behavioral therapy (n = 88), Internet-based problem-solving therapy (n = 88), and a waiting list (n = 87). End points were evaluated at the 12-week follow-up.

Results

Cost-utility analysis showed that cognitive behavioral therapy and problem-solving therapy had a 52% and 61% probability respectively of being more acceptable than waiting when the willingness to pay is € 30,000 for one quality-adjusted life-year. When society is prepared to pay € 10,000 for a clinically significant change from depression, the probabilities of cognitive behavioral therapy and problem-solving therapy being more acceptable than waiting are 91% and 89%, respectively. Comparing both Internet-based treatments showed no clear preference for one or the other of the treatments.

Conclusions

Both Internet-based treatments have a high probability of being cost-effective with a modest value placed on clinically significant change in depressive symptoms.

Identifying suspected breast cancer: development and validation of a clinical prediction rule

Background

An evidence-based approach is needed to identify women with breast symptoms who are most likely to have breast cancer so that timely and appropriate referral can take place.

Aim

To report the development and validation of a clinical prediction rule for the diagnosis of breast cancer.

Design and setting

Cohort study with two prospective groups of women: those presenting to a symptomatic breast clinic (derivation cohort) and a separate cohort presenting to 11 general practices (validation cohort) in Tayside, Scotland.

Method

Regression analysis was used to derive a clinical prediction rule from presenting symptoms, personal and family history, and clinical findings. Validation consisted of estimating the number of breast cancers predicted to occur compared with the actual number of observed breast cancers across deciles of risk.

Results

In the derivation cohort of 802 patients, 59 (7%) were diagnosed with breast cancer. Independent clinical predictors for breast cancer were: increasing age by year (adjusted odds ratio [AOR] 1.10, 95% confidence interval [CI] = 1.07 to 1.13); presence of a discrete lump (AOR 15.20, 95% CI = 4.88 to 47.34); breast thickening (AOR 7.64, 95% CI = 2.23 to 26.11); lymphadenopathy (AOR 3.63, 95% CI = 1.33 to 9.92); and lump ≥2 cm (AOR 5.41, 95% CI = 2.36 to 12.38). All eight patients with skin tethering had breast cancer. The regression model had good predictive power, identifying all five breast cancers in the validation cohort of 97 patients in the top two deciles of risk.

Conclusion

The clinical prediction rule discriminates between patients at high risk of breast cancer from those at low risk, and can be implemented as an evidence-based recommendation to enhance appropriate referral from general practice to a symptomatic breast clinic. Ongoing validation in further populations is required.     

Is a Severe Clinical Profile an Effect Modifier in a Web-Based Depression Treatment for Adults With Type 1 or Type 2 Diabetes? Secondary Analyses From a Randomized Controlled Trial

Background

Depression and diabetes are two highly prevalent and co-occurring health problems. Web-based, diabetes-specific cognitive behavioral therapy (CBT) depression treatment is effective in diabetes patients, and has the potential to be cost effective and to have large reach. A remaining question is whether the effectiveness differs between patients with seriously impaired mental health and patients with less severe mental health problems.

Objective

To test whether the effectiveness of an eight-lesson Web-based, diabetes-specific CBT for depression, with minimal therapist support, differs in patients with or without diagnosed major depressive disorder (MDD), diagnosed anxiety disorder, or elevated diabetes-specific emotional distress (DM-distress).

Methods

We used data of 255 patients with diabetes with elevated depression scores, who were recruited via an open access website for participation in a randomized controlled trial, conducted in 2008–2009, comparing a diabetes-specific, Web-based, therapist-supported CBT with a 12-week waiting-list control group. We performed secondary analyses on these data to study whether MDD or anxiety disorder (measured using a telephone-administered diagnostic interview) and elevated DM-distress (online self-reported) are effect modifiers in the treatment of depressive symptoms (online self-reported) with Web-based diabetes-specific CBT.

Results

MDD, anxiety disorder, and elevated DM-distress were not significant effect modifiers in the treatment of self-assessed depressive symptoms with Web-based diabetes-specific CBT.

Conclusions

This Web-based diabetes-specific CBT depression treatment is suitable for use in patients with severe mental health problems and those with a less severe clinical profile.

Contribution of cancer symptoms, dysfunctional sleep related thoughts, and sleep inhibitory behaviors to the insomnia process in breast cancer survivors: a daily process analysis

Study Objectives:

Using a comprehensive cognitive-behavioral model of insomnia and a daily process approach, this study was conducted to examine the contribution of cancer symptoms and dysfunctional sleep related thoughts and behaviors to the process of insomnia in breast cancer survivors.

Design:

Within-group longitudinal research design.

Setting:

An academic medical center.

Participants:

41 women with breast cancer who had completed their primary cancer treatment and met Research Diagnostic Criteria for primary insomnia or insomnia comorbid with breast cancer.

Interventions:

NA

Measurements and Results:

For 28 days, participants completed morning diaries assessing sleep, nighttime pain and hot flashes, and dysfunctional sleep related thoughts and behaviors during the day and night, and evening diaries assessing daytime pain, fatigue, hot flashes, and mood. All diaries were collected using an automated telephone-based system. Results revealed that poorer sleep was related to nighttime pain and hot flashes in breast cancer patients. Time-lagged effects were also found. The current study identified higher levels of dysfunctional sleep related thoughts and sleep inhibitory behaviors during the day and night as antecedents of insomnia, and higher levels of pain, fatigue, and hot flashes and lower levels of positive mood and dysfunctional sleep related thoughts as consequences of insomnia in this population.

Conclusions:

The current study found support for a comprehensive cognitive-behavioral model of insomnia, which has several theoretical, practice, and research implications.

Sleep and Depression in Postpartum Women: A Population-Based Study

Study Objectives:

(1) To describe the prevalence of and risk factors for postpartum maternal sleep problems and depressive symptoms simultaneously, (2) identify factors independently associated with either condition, and (3) explore associations between specific postpartum sleep components and depression.

Design:

Cross-sectional.

Setting:

Population-based.

Participants:

All women (n = 4191) who had delivered at Stavanger University Hospital from October 2005 to September 2006 were mailed a questionnaire seven weeks postpartum. The response rate was 68% (n = 2830).

Interventions:

None.

Measurements and results:

Sleep was measured using the Pittsburgh Sleep Quality Index (PSQI), and depressive symptoms using the Edinburgh Postnatal Depression Scale (EPDS). The prevalence of sleep problems, defined as PSQI > 5, was 57.7%, and the prevalence of depression, defined as EPDS ≥ 10, was 16.5%. The mean self-reported nightly sleep duration was 6.5 hours and sleep efficiency 73%. Depression, previous sleep problems, being primiparous, not exclusively breastfeeding, or having a younger or male infant were factors associated with poor postpartum sleep quality. Poor sleep was also associated with depression when adjusted for other significant risk factors for depression, such as poor partner relationship, previous depression, depression during pregnancy and stressful life events. Sleep disturbances and subjective sleep quality were the aspects of sleep most strongly associated with depression.

Conclusions:

Poor sleep was associated with depression independently of other risk factors. Poor sleep may increase the risk of depression in some women, but as previously known risk factors were also associated, mothers diagnosed with postpartum depression are not merely reporting symptoms of chronic sleep deprivation.

Effects of a multidisciplinary cognitive rehabilitation program for patients with mild Alzheimer's disease

OBJECTIVE:

To evaluate the effects of a multidisciplinary rehabilitation program on cognition, quality of life, and neuropsychiatric symptoms in patients with mild Alzheimer''s disease.

METHOD:

The present study was a single-blind, controlled study that was conducted at a university-based day-hospital memory facility. The study included 25 Alzheimer''s patients and their caregivers and involved a 12-week stimulation and psychoeducational program. The comparison group consisted of 16 Alzheimer''s patients in waiting lists for future intervention.

INTERVENTION:

Group sessions were provided by a multiprofessional team and included memory training, computer-assisted cognitive stimulation, expressive activities (painting, verbal expression, writing), physiotherapy, and physical training. Treatment was administered twice a week during 6.5-h gatherings.

MEASUREMENTS:

The assessment battery comprised the following tests: Mini-Mental State Examination, Short Cognitive Test, Quality of Life in Alzheimer''s disease, Neuropsychiatric Inventory, and Geriatric Depression Scale. Test scores were evaluated at baseline and the end of the study by raters who were blinded to the group assignments.

RESULTS:

Measurements of global cognitive function and performance on attention tasks indicated that patients in the experimental group remained stable, whereas controls displayed mild but significant worsening. The intervention was associated with reduced depression symptoms for patients and caregivers and decreased neuropsychiatric symptoms in Alzheimer''s subjects. The treatment was also beneficial for the patients'' quality of life.

CONCLUSION:

This multimodal rehabilitation program was associated with cognitive stability and significant improvements in the quality of life for Alzheimer''s patients. We also observed a significant decrease in depressive symptoms and caregiver burden. These results support the notion that structured nonpharmacological interventions can yield adjunct and clinically relevant benefits in dementia treatment.
