The role of marital interaction in chronic pain and depressive symptom severity

Several investigators have noted the moderating role of the spouse in determining the severity and disability associated with the experience of chronic pain. In this study, pain-contingent responses from spouses, but not global marital satisfaction, accounted for a significant proportion of the variance in reported pain severity. Global marital satisfaction predicted depressive symptom severity. The interaction between global marital satisfaction and the reported frequency of punishing responses to pain behavior added significantly to the prediction of depressive symptoms. Similarly, the interaction between marital satisfaction and degree of spouse solicitousness significantly predicted pain severity. These results are consistent with evolving literatures on the important relationship between marital distress, aversive communication and depression on the one hand, and the potentially deleterious role of the solicitous spouse in the maintenance of chronic pain on the other.     

A comparison of alternative assessments of depressive symptom severity: a pilot study

This study compared the performance of an itemized symptom self-report (Inventory of Depressive Symptomatology - Self-Report; IDS-SR), patient global ratings, and clinician global ratings with an itemized clinician-rated symptom severity measure (Inventory of Depressive Symptomatology - Clinician-Rated; IDS-C) in detecting treatment effects in patients with major depressive disorder (MDD). A total of 28 inpatients (30.8% psychotic) and 34 outpatients (17.9% psychotic) with MDD began treatment that followed the Texas medication algorithm. The clinicians completed the IDS-C and a Physician Global Rating Scale (PhGRS) at each assessment visit, while the patients completed the IDS-SR and a Patient Global Rating Scale (PtGRS). Change scores from the baseline to subsequent weeks were computed for all subjects, utilizing all four measures. The IDS-SR was a significant independent predictor of the response to treatment as compared to the two global ratings. The IDS-SR was as sensitive to change as the IDS-C. While the clinician-rated itemized symptom severity rating scale remains the standard to assess the symptomatic outcome of the treatment of MDD, a self-report of identical symptomatology may be a reasonable alternative for many patients.

Social networks and depressive symptoms among elderly women and men in Havana, Cuba

OBJECTIVES: To examine the main and the stress-buffering effects of social networks on depressive symptoms among elderly Cuban men and women living in La Havana. METHOD: Information was gathered from a representative sample of the elderly population in Havana (n = 1905), as part of the SABE (Salud, Bienestary Enuejecimiento) study. Depressive symptoms were measured using the 15-item Geriatric Depression Scale. The structure and function of social networks were studied. Gender-specific multivariate logistic regressions were fitted to test the main (independent of stressors) and the stress-buffering effects (in the presence of financial strain or disabilities) on depressive symptoms. RESULTS: Social ties were associated with a lower prevalence of depressive symptoms in women and men independently of the presence of stressors. Women who were or had been married, lived in an extended family, and enjoyed balanced exchanges with relatives and children reported low prevalence of depressive symptoms. Men were less likely to report depressive symptoms if they were currently married, and did not live alone. Social networks buffered the effect of financial strain on depression, but not in the event of disability. CONCLUSION: In Cuba, networks centered on children and extended family were associated with low frequency of depressive symptoms, ruling contrary to common findings in developed societies. These living arrangements have an important role in buffering the impact of financial strain on depressive symptoms.     

Community knowledge of and attitudes toward epilepsy in rural and urban Mukono district,Uganda: A cross-sectional study

IntroductionThe lack of adequate knowledge poses a barrier in the provision of appropriate treatment and care of patients with epilepsy within the community. The purpose of this study was to determine the knowledge of and attitude towards epilepsy and its treatment by community dwellers in Uganda.MethodsA cross sectional population survey was conducted in urban and rural Mukono district, central Uganda. Adult respondents through multistage stratified sampling were interviewed about selected aspects of epilepsy knowledge, attitudes, and perception using a pretested structured questionnaire.ResultsNinety-one percent of the study respondents had heard or read about epilepsy or knew someone who had epilepsy and had seen someone having a seizure. Thirty-seven percent of the respondents did not know the cause of epilepsy, while 29% cited genetic causes. About seventeen percent of the subjects believed that epilepsy is contagious. Only 5.6% (21/377) of the respondents would take a patient with epilepsy to hospital for treatment.ConclusionAdults in Mukono are very acquainted with epilepsy but have many erroneous beliefs about the condition. Negative attitudes are pervasive within communities in Uganda. The national epilepsy awareness programs need to clarify the purported modes of transmission of epilepsy, available treatment options, and care offered during epileptic seizures during community sensitizations in our settings.     

Neural correlates of communication skill and symptom severity in autism: A voxel-based morphometry study

Although many studies have compared the brains of normal controls and individuals with autism, especially older, higher-functioning individuals with autism, little is known of the neural correlates of the vast clinical heterogeneity characteristic of the disorder. In this study, we used voxel-based morphometry (VBM) to examine gray matter correlates of variation in communication skill and symptom severity within a heterogeneous group of 33 children with autism ranging in age from 3.4 to 11.4 years. Greater gray matter (GM) volume was associated with better communication skills in numerous frontal regions, especially in the left middle frontal gyrus. Further, greater GM volume in the right inferior frontal gyrus was associated with reduced severity of symptoms of autism. However, increased total GM volume was correlated with more severe symptoms of autism at a trend level, consistent with other studies, suggesting that while increased total GM volume is generally predictive of greater autistic severity, specific local increases in GM volume result in a reduction in symptoms. Our results suggest that communication and symptom severity have distinct neuroanatomic correlates and draw attention to the importance of studying the neuroanatomy of clinical heterogeneity within the autistic population.     

Childhood sexual abuse and depressive symptom severity: the role of neuroticism

This study examined neuroticism's role in the association between childhood sexual abuse and severity of depressive symptoms in a sample of 105 psychiatric patients 50 years of age and older diagnosed with major depressive disorder. As hypothesized, men and women who reported histories of childhood sexual abuse had more severe depressive symptoms than those without abuse histories. Further, neuroticism partially accounted for the association between severe childhood sexual abuse and depressive symptom severity. Self-consciousness, a facet of neuroticism conceptually related to shame, also partially accounted for that relationship. These findings suggest that neuroticism may be one way in which childhood sexual abuse contributes to depressive symptoms in later life. Prospective studies are needed.     

Prospective study of cardiorespiratory fitness and depressive symptoms in women and men

Most studies of the relationship between cardiorespiratory fitness (CRF) and depression have been limited to cross-sectional designs. The objective of this study was to follow individuals over time to examine whether those with higher levels of CRF have lower risk of developing depressive symptoms. Participants were 11,258 men and 3085 women enrolled in the Aerobics Center Longitudinal Study in Dallas, TX. All participants completed a maximal treadmill exercise test at baseline (1970-1995) and a follow-up health survey in 1990 and/or 1995. Individuals with a history of a mental disorder, cardiovascular disease, or cancer were excluded. CRF was quantified by exercise test duration, and categorized into age and sex-stratified groups as low (lowest 20%), moderate (middle 40%), or high (upper 40%). Depressive symptoms were assessed using the 20-item Center for Epidemiologic Studies Depression Scale (CES-D). Those who scored 16 or more on the CES-D were considered to have depressive symptoms. After an average of 12 years of follow-up, 282 women and 740 men reported depressive symptoms. After adjusting for age, baseline examination year, and survey response year, the odds of reporting depressive symptoms were 31% lower for men with moderate CRF (odds ratio, OR 0.69; 95% confidence interval, CI 0.56-0.85) and 51% lower for men with high CRF (OR 0.49, CI 0.39-0.60), compared to men with low CRF. Corresponding ORs for women were 0.56 (CI 0.40-0.80) and 0.46 (CI 0.32-0.65). Higher CRF is associated with lower risk of incident depressive symptoms independent of other clinical risk predictors.     

Major depressive disorder and marital transition among mothers: results from a national panel study

This analysis employs a national panel study to examine the relationship between marital transition and depression among mothers within the framework of selection and causation processes. The data come from the two-wave, longitudinal National Population Health Survey (NPHS) by Statistics Canada collected in 1994 and again in 1996 focusing on women between 20 and 65 years of age with children living at home (N = 2169). Compared with mothers who remain married, mothers making the transition into single-parenthood had a significantly higher rate of major depression at Time 1, which increased, but not significantly, at Time 2. This suggests that a selection effect may explain the elevated levels of depression among mothers experiencing a marital disruption. Rates of depression among single-parent mothers making the transition into a marital relationship did not decrease significantly between waves nor did the rate differ significantly from stable single-parent mothers at Time 1 or Time 2, suggesting that movement into marriage is not a protective factor.     

Assessment of depression prevalence in rural Uganda using symptom and function criteria

Abstract. Background: We sought to assess the prevalence of major depression in a region of sub-Saharan Africa severely affected by HIV, using symptom and functional criteria as measured with locally validated instruments. Method: Six hundred homes in the Masaka and Rakai districts of southwest Uganda were selected by weighted systematic random sampling. A locally validated version of the depression section of the Hopkins Symptom Check List (DHSCL) and a community-generated index of functional impairment were used to interview 587 respondents. Results: Of respondents,21% were diagnosed with depression using three of the five DSM-IV criteria (including function impairment) compared with 24.4 % using symptom criteria alone. Increased age and lower educational levels are associated with a greater risk for depression; however, a gender effect was not detected. Conclusions: Most community-based assessments of depression in sub-Saharan Africa based on the DSM-IV have used symptom criteria only.We found that expanding criteria to more closely match the complete DSM-IV is feasible, thereby making more accurate assessments of prevalence possible. This approach suggests that major depression and associated functional impairment are a substantial problem in this population.     

Prospective study of maternal depressive symptomatology among Japanese women

Background

The primary objective of this study was to analyze the pattern of depressive moods related to pregnancy and postpartum in a dataset collected prospectively. A secondary objective was to assess the association between (1) low moods during pregnancy and postpartum depressive symptoms, and (2) maternity blues and postpartum depressive symptom.

Method

Three hundred eighty-seven women completed self-administered questionnaires. The participants were asked to respond to Stein's Maternity Blues Scale (Stein's Scale) on five consecutive days after delivery and to the Edinburgh Postnatal Depression Scale (EPDS) during both pregnancy and postpartum.

Results

32.0% of the women were identified as having a score of more than 9 on EPDS during pregnancy and postpartum. 21.6% of the women scored above the Stein's Scale cut-off point for at least 1 day during the 5-day period following delivery. The odds ratio (95% CI) for postpartum low mood if the women experienced low mood during pregnancy was 4.46 (2.48–8.04), while the odds ratio for postpartum depressive symptoms if the women experienced symptoms of maternity blues was 5.48 (2.74–10.98). In logistic regression analysis, the number of days in which women scored over the cut-off point by Stein's Scale proved to be the more significant predictor of scoring over the EPDS cutoff (8/9) [OR (95% CI)=2.74 (1.89–3.96)].

Conclusion

The rate of maternity blues in our findings was similar to the rates previously reported in Japan, but lower than the rates observed in Western countries. Furthermore, our longitudinal study confirms the likelihood of subsequent postpartum depressive symptoms if low moods during pregnancy and/or maternity blues are present.     

Altered empathic responding in major depressive disorder: relation to symptom severity, illness burden, and psychosocial outcome

Individuals with major depressive disorder (MDD) demonstrate deficits in multiple social cognitive domains; however, systematic investigations of empathic responding have not been performed. Twenty patients with MDD completed two measures of empathy, the Interpersonal Reactivity Index (IRI: Davis, 1980, 1983) and the Toronto Empathy Questionnaire (TEQ: Spreng et al., 2009). Relative to matched controls, patients with MDD reported significantly reduced levels of empathy measured broadly on the TEQ and specifically in cognitive (‘Perspective Taking’) and affective (‘Empathic Concern’) domains captured by the IRI. A higher illness burden (i.e., greater number of past depressive episodes) was associated with greater reductions in perspective taking ability. This study provides early evidence of impaired empathic abilities in patients with MDD that may worsen with illness progression. Alternatively, reductions in perspective taking ability may contribute to a more severe course of illness in this population. Further longitudinal work is needed to characterize the relation between social cognitive performance and social functioning in this population.     

Brain imaging correlates of depressive symptom severity and predictors of symptom improvement after antidepressant treatment.

BACKGROUND: It would be therapeutically useful to predict clinical response to antidepressant drugs. We evaluated structural magnetic resonance imaging (MRI) and functional MRI (fMRI) data as predictors of symptom change in people with depression. METHODS: Brain structure and function were measured with MRI in 17 patients with major depression immediately before 8 weeks treatment with fluoxetine 20 mg/day. For fMRI, patients were scanned during visual presentation of faces representing different intensities of sadness. Clinical response was measured by change in serial scores on the Hamilton Rating Scale for Depression. Symptom change scores (and baseline symptom severity) were regressed on structural and functional MRI data to map brain regions where grey matter volume, or activation by sad facial affect processing, was significantly associated with symptom change (or baseline severity). RESULTS: Faster rates of symptom improvement were strongly associated with greater grey matter volume in anterior cingulate cortex, insula, and right temporo-parietal cortex. Patients with greater than median grey matter volume in this system had faster rates of improvement and significantly lower residual symptom scores after 8 weeks' treatment. Faster improvement was also predicted by greater functional activation of anterior cingulate cortex. Baseline symptom severity was negatively correlated with greater grey matter volume in dorsal prefrontal and anterior midcingulate regions anatomically distinct from the pregenual and subgenual cingulate regions predicting treatment response. CONCLUSIONS: Structural MRI measurements of anterior cingulate cortex could provide a useful predictor of antidepressant treatment response.     

Effects of exercise and weight loss on depressive symptoms among men and women with hypertension

OBJECTIVE: This study aimed to investigate changes in depressive symptoms in hypertensive individuals participating in an exercise and weight loss intervention. METHODS: This study involved 133 sedentary men and women with high blood pressure (BP; 130-180 mmHg systolic BP and/or 85-110 mmHg diastolic BP) who participated in a 6-month intervention consisting of three groups: aerobic exercise, aerobic exercise and weight loss, and a waiting list control. RESULTS: Participants in both treatment groups demonstrated significant improvements in aerobic capacity and lower BP compared with participants in the control group. Participants in the active treatment groups who had mild to moderate depressive symptoms at baseline also exhibited greater reductions in depressive symptoms compared with participants in the control group. CONCLUSION: Results from the present study suggest that exercise, alone or combined with weight management, may reduce self-reported depressive symptoms among patients with hypertension.     

Life satisfaction and happiness associated with depressive symptoms among university students: a cross-sectional study in Korea

Background

This cross-sectional study investigated the impact of life satisfaction and happiness, as well as the prevalence and correlates of depressive symptoms in a large sample of university students.

Methods

We included 2338 students at 6 universities in 1 metropolitan city and 2 provinces of Korea. Depressive symptoms were assessed by the Beck Depression Inventory, and scores of 16 or higher were categorized as the presence of depression. Various sociodemographic, life satisfaction, happiness, and clinical factors (alcohol consumption and sleep quality) were measured. According to the presence of depression, sociodemographic, life satisfaction, happiness, and clinical characteristics were compared using statistical analyses. Further, a logistic regression model was constructed to examine the impact of life satisfaction, happiness, and clinical factors on depression.

Results

Among participants, 13.4% were identified as having depression. Life satisfaction and happiness were associated with a lower risk of depression, while hazardous alcohol drinking and poor sleep quality were related to a higher risk of depression. In addition, female gender, subjective body shape as obese, and insufficient pocket money were found to be significant correlates of depressive symptoms.

Conclusions

This study demonstrated possible risk and protective factors of underlying depressive symptoms. Especially, our findings suggest that improvement in life satisfaction and happiness would be important in the prevention and management of depression. Our findings may contribute to developing specialized mental health programs for prevention, screening, and treatment of depression among university students.

     

Habitual sleep patterns and the distribution of body mass index: cross-sectional findings among Swedish men and women

Objective

To compare distributions of body mass index (BMI) between individuals with different habitual sleep patterns.

Methods

We performed cross-sectional analyses of 40,197 Swedish adults (64% women), who reported sleep duration and quality, weight, height, and possible confounding factors in 1997. Using quantile regression, we estimated associations between sleep patterns and selected percentiles of the distribution of BMI.

Results

While the medians were similar, larger adjusted values of BMI were estimated in the upper part of the distribution among men and women with short sleep (≤5 h) compared with medium-length sleep (6–8 h). For example, in men, the 90th percentile of BMI was 0.80 kg/m² (95% confidence interval: 0.17–1.43 kg/m²) higher among short sleepers. In women, long sleepers (≥9 h) also showed larger values in the upper part of the BMI distribution; the 90th percentile was 1.23 kg/m² (0.42–2.04 kg/m²) higher than in medium-length sleepers. In male long sleepers, smaller values were estimated in the lower part of the BMI distribution; the 10th percentile was 0.84 kg/m² lower (0.35–1.32 kg/m²) than in medium-length sleepers. The 90th percentile of BMI in women with poor-quality compared with good-quality sleep was larger by 0.82 kg/m² (0.47–1.16 kg/m²); the 10th percentile was smaller by 0.17 kg/m² (0.02–0.32 kg/m²).

Conclusions

Short, long or poor-quality sleepers showed larger, or smaller, values at the tails of the BMI distribution, but similar medians. Hence, unfavorable sleep patterns and BMI were associated only in a subset of this study population.     

Functional impairment among people with severe and enduring mental disorder in rural Ethiopia: a cross-sectional study

Purpose

Evidence regarding functional impairment in people with severe mental disorders (SMD) is sparse in low- and middle-income countries. The aim of this study was to identify factors associated with functional impairment in people with enduring SMD in a rural African setting.

Methods

A cross-sectional study was conducted at the baseline of a health service intervention trial. A total of 324 participants were recruited from an existing community-ascertained cohort of people with SMD (n?=?218), and attendees at the Butajira General Hospital psychiatric clinic (n?=?106). Inclusion criteria defined people with SMD who had ongoing need for care: those who were on psychotropic medication, currently symptomatic or had a relapse in the preceding 2 years. The World Health Organization Disability Assessment schedule (WHODAS-2.0) and the Butajira Functioning Scale (BFS) were used to assess functional impairment. Multivariable negative binomial regression models were fitted to investigate the association between demographic, socio-economic and clinical characteristics, and functional impairment.

Results

Increasing age, being unmarried, rural residence, poorer socio-economic status, symptom severity, continuous course of illness, medication side effects, and internalized stigma were associated with functional impairment across self-reported and caregiver responses for both the WHODAS and the BFS. Diagnosis per se was not associated consistently with functional impairment.

Conclusion

To optimize functioning in people with chronic SMD in this setting, services need to target residual symptoms, poverty, medication side effects, and internalized stigma. Testing the impact of community interventions to promote recovery will be useful. Advocacy for more tolerable treatment options is warranted.
