Quality of Life and Psychological Wellbeing of Colorectal Cancer Survivors in the KSA

Introduction: Colorectal cancer (CRC) ranked first among cancers reported in males and ranked third amongst females in Saudi Arabia. CRC cancer symptoms or symptoms secondary to treatment, such as diarrhea, constipation, fatigue and loss of appetite are very common and has significant negative effects on the quality of life (QoL). Methods: This project was a cross-sectional study of colorectal cancer survivors diagnosed between 1 January 2015 and May 2017. Assessment was performed using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30), the colorectal cancer specific module (EORTC QLQ-CR 29) and the Hospital Anxiety and Depression Scale (HADS). Data on potential predictors of scores were also collected. Results: 115 CRC patients from Middle, Eastern and Western regions of the KSA participated in the study. Participants have unexpectedly low global health score with a mean of 56.9±31.3. Physical functioning scale had the lowest score of 61.3±27.7. Regarding the generic symptoms of cancer, fatigue was the worst symptom, followed by appetite loss. Psychological wellbeing assessment utilizing HADS reveals alarming outcomes for survivors of CRC in the KSA with high proportion of participants with moderate to severe depression (55%) and a good proportion of participants with moderate to high anxiety (31%). Only 3.7% of participants reported receiving psychosocial support. Discussion: Results of this project reveal an overall trend of low scores of quality of life amongst colorectal cancer patients in the KSA when compared with regional or international figures. Consistent results for psychological wellbeing were reached. We recommend routine screening for quality of life and psychological wellbeing and including the outcomes per individual patient care. Psychological support is highly needed for cancer survivors.     

Quality of Life and Psychological Well-Being of Breast Cancer urvivors in Jordan

Introduction: Breast cancer is the most common cancer among Jordanians. Breast cancer patients sufferfrom several negative consequences after treatment and these include pain, fatigue, sexual problems, appearanceand body image concerns, with psychological dysfunction. This could affect the patient quality of life andpsychological well-being. To the best of our knowledge, there is no published quantitative data on the quality oflife and psychological well-being of breast cancer patients in Jordan. The objective of this study was to obtainsuch data and assess predictors with calculated scores. Methods: In this cross-sectional study conducted amongbreast cancer patients in Jordan diagnosed in 2009 and 2010, assessment was performed using the EuropeanOrganization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30), theBreast Module (QLQ-BR23) and the Hospital Anxiety and Depression Scale (HADS). Clinical, demographic andpsychosocial indicators that could predict patient quality of life scores were collected. Results: The number ofpatients interviewed was 236 (mean age=50.7±10.7 years). The mean Global Health score for the QLQ-C30 was63.7±20.2 SD. Among functional scales, “social functioning” scored the highest (mean=78.1±28.6 SD), whereas“emotional functioning” scored the lowest (mean=59.0±SD 33.5). For the QLQ-BR23, the worst scores withinthe functional scales were for “body image” (mean=52.1±36.8 SD) and “future perspective” (mean=52.9±38.5SD) . The worst symptom was “upset by hair loss” (mean=69.8±43.0). The mean HADS scores was 18.±9.0 SD.Out of study participants, 53% scored abnormal on the anxiety scale and 45% on the depression scale. Severedepression and severe anxiety were detected among 8% and 14% of study participants, respectively. Statisticallysignificant predictors for individual scores were similar to those reported in published studies, such as the presenceof recurrence since baseline, family history of cancer, low educational status, current social problems, extent ofthe disease, presence of financial difficulties, and employment status. Conclusions and Recommendations: Breastcancer survivors in Jordan have overall good quality of life scores when compared with patients from Westerncountries. However, their psychological wellbeing is more impaired. There is an urgent need for psychosocialsupport programs and psychological screening and consultation for breast cancer patients at hospitals of theMinistry of Health in Jordan.     

Quality of Life and Psychological Well-Being of Colorectal Cancer Survivors in Jordan

Background: Colorectal ranked first among cancers reported in males and ranked second amongst femalesin Jordan, accounting for 12.7% and 10.5% of cancers in males and females, respectively. Colorectal cancerpatients can suffer several consequences after treatment that include pain and fatigue, constipation, stomacomplications, sexual problems, appearance and body-image concerns as well as psychological dysfunction. Thereis no published quantitative data on the health-related quality of life and psychological wellbeing of Jordaniancolorectal cancer survivors. Method: This project was a cross-sectional study of colorectal cancer survivorsdiagnosed in 2009 and 2010. Assessment was performed using the European Organization for Research andTreatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30), the colorectal cancer specific module(EORTC QLQ-CR 29) and the Hospital Anxiety and Depression Scale (HADS). Data on potential predictorsof scores were also collected. Results: A total of 241 subjects completed the study with mean age of 56.7±13.6.Males represented 52.3% of study participants. A majority of participants reported good to high overall health;the mean Global health score was 79.74± 23.31 with only 6.64% of study participants scoring less than 33.3%.The striking result in this study was that none of the study participants participated in a psychosocial supportgroup; only 4 of them (1.7%) were even offered such support. The mean scores for HADS, depression score, andanxiety score were 8.25±9, 4.35±4.9 and 3.9±4.6, respectively. However, 77.1% of study participants were withinthe normal category for the depression score and 81.7% were within this category for anxiety score; 5.4% ofparticipants had severe anxiety and 5.4% of them had severe depression. Discussion: Patients with colorectalcancer in Jordan have a good quality of life and psychological wellbeing scores when compared with patientsfrom western countries. None of the colorectal cancer patients managed at the Ministry of Health received anyformal counselling, or participated in psychological or social support programmes. This highlights the urgentneed for a psychosocial support programme, psychological screening and consultations for patients diagnosedwith colorectal cancer at the Ministry of Health Hospitals.     

Health-related quality of life in disease-free survivors of breast cancer with the general population.

BACKGROUND: Although most of the literature about health-related quality of life (HRQoL) focuses on breast cancer patients, few studies compared the HRQoL in disease-free breast cancer survivors with that of the general population. MATERIALS AND METHODS: We administered the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 and Quality of Life Questionnaire Breast Cancer Module, McGill Quality of Life Questionnaire, Beck Depression Inventory, and Brief Fatigue Inventory to 1933 disease-free survivors for over 1 year after being diagnosed with stage 0 to III breast cancer. We performed multivariate-adjusted analyses in all HRQoL comparisons. RESULTS: The scores for some HRQoL scales were comparable for both disease-free breast cancer survivors and the general female population; however, there was clinically significant difference in cognitive and social functioning, fatigue, insomnia, and financial difficulties between the two groups. Radiotherapy and systemic adjuvant therapy variables did not limit the HRQoL. Demographic characteristics such as age, time since surgery, and comorbidity were associated with some HRQoL scales and fatigue and depression were associated with almost all HRQoL scales. CONCLUSIONS: Disease-free survivors of breast cancer had good HRQoL, which was less affected by the type of treatment than it was by demographic characteristics, time since surgery, comorbidity, fatigue, and depression.     

Long-term quality of life after breast cancer: a French registry-based controlled study

Population-based studies on quality of life (QOL) of long-term breast cancer survivors are quite recent and insufficient attention has been paid to the effect of time since diagnosis. We compared long-term QOL of population-based breast cancer survivors 5, 10, and 15 years after diagnosis with that of healthy controls. Breast cancer survivors were randomly selected from three population-based cancer registries (Bas-Rhin, Calvados and Doubs, France) along with healthy controls, stratified for age and place of residence, randomly selected from electoral rolls. Participants completed five self-administered questionnaires: the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30), Short Form-36 (SF-36), Spielberger State-Trait Anxiety Inventory (STAI), Multidimensional Fatigue Inventory (MFI) and a life conditions questionnaire. An analysis of variance was used to compare QOL scores of breast cancer survivors by period (5, 10, or 15 years) of diagnosis with those of controls, adjusted for sociodemographic data and comorbidities. Six hundred and fifty-two cases and 1,188 controls participated in the study. For many QOL scales, scores were significantly different between cancer survivors and controls. A clinically significant difference was evidenced for the fatigue scales, the SF36 physical functioning, role-physical, and role-emotional scales, with more favorable results for controls. Differences decreased with time and 15-year cancer survivors were generally not different from controls. Scores were particularly influenced by age and mean household income. More efforts should be made, specifically during the first 5 to 10 years after diagnosis, to help women with breast cancer to overcome their impairment in QOL.     

The Efficacy of Psychoeducational Support Group for Saudi Breast Cancer Survivors

Background: The adverse effects of psychological distress and quality of life are common outcomes in breast cancer survivors. Psychoeducational interventions have been widely used to reduce these adverse outcomes among those patients. This study aims to assess the impact of the Blossom support group on psychological distress and quality of life in breast cancer patients in Saudi Arabia. Methods: This study is a retrospective cohort study for the Blossom program, which was held yearly for eight weeks from 2014 until 2018. Data was collected from the survivors’ records at the Zahra Breast Cancer Association in Riyadh, Saudi Arabia. Outcome measurements: include the quality of life scale (SF-36) and Hospital Anxiety Depression Scale (HADS) with both were available in the Arabic translated version. Both tools were used as the screening measurement for the assessment of the quality of life, depression, and anxiety before and after the program. The data were analyzed using the Statistical Analytical Software (SAS), version 9.4. Statistical differences in median scores of SF-36 and HADS before and after the program was tested using Wilcoxon signed-rank test. Result: A total of 54 breast cancer survivors were enrolled in the Blossom support program over the period 2014 to 2018. Of these participants, only 25 participants completed the full eight weeks program.  There were statistically significant differences in the overall quality of life (SF-36) before and after the 8 weeks from baseline of the experiment (W = 60, P-value =0.0125). Moreover, the overall anxiety and depression scores were tested separately and the results reveal statistically significant differences in both dimensions before and after the program (Anxiety: W=132, P-value = 0.0059; depression: W=157, P-value = 0.0002). Conclusion: The Blossom support program showed a positive impact on the quality of life and the psychological well-being of breast cancer survivors. It is recommended to utilize this support program across a wide range of health organizations with breast cancer survivors as a baseline of psychological care to improve the quality of life.     

Anxiety,Depression and Quality of Life in Breast Cancer Patients in the Levant

Background: Limited data are currently available regarding the psychological well-being and quality of life of breast cancer patients after active treatment in Lebanon and the Arab region in general. The objective of this study was to determine the prevalence of anxiety and depression among Arab breast cancer patients and assess the quality of life with reference to socio-demographic and clinical characteristics. Methods: This cross-sectional study was conducted among female breast cancer patients diagnosed between January 2009 and March 2014, who were recruited from the outpatient clinics of Naef K. Basile Cancer Institute at the American University of Beirut Medical Center (AUBMC) from November 2015 till December 2016. An interview was conducted utilizing two validated questionnaires: the Hospital Anxiety and Depression Scale (HADS) and the Functional Assessment of Cancer Therapy-Breast (FACT-B). Socio-demographic and clinical characteristics that might predict patient quality of life were collected and summarized. Results: A total of 150 patients were interviewed (median age 53.5±10.4 years). Most were assessed 3 to 5 years (68.7%) after initial diagnosis and had undergone surgery, chemotherapy, radiation, or hormonal therapy (97.3%, 79.3%, 80.7% and 86.0%, respectively). The median total HADS score was 10.0 ± 8.0, with approximately 41.3% of study participants having abnormal scores on the anxiety subscale and 24.7% on the depression subscale. Significant predictors of total HADS score were nationality and level of education (p=0.001, p=0.001 respectively; R2=0.181). Participants who were Iraqi, had stage IV disease, had a household monthly income below 1000 USD, or had received chemotherapy exhibited significantly lower total FACT-B scores, these being highly negatively correlated with total HADS scores (rs= -0.73, p=0.001). Conclusion: There is a vital need for the development of individualized interventions and psychosocial support programs tailored to the physical and psychological well-being of breast cancer patients in the Levant region.     

Psychometric evaluation of the Brief Cancer Impact Assessment among breast cancer survivors

OBJECTIVES: The increasing number of cancer survivors brings greater attention to the biopsychosocial impact of surviving cancer. Instruments exist that measure quality of life (QOL), symptoms, and specific types of functioning after cancer; however, a reliable and valid assessment of the perceived impact of cancer (IOC) on the life plans and activities of cancer survivors has been missing. This study evaluated the psychometric properties of the 16-item Brief Cancer Impact Assessment (BCIA). METHODS: Factor analysis with Promax oblique rotation established the factor structure of the BCIA in 783 ethnically diverse breast cancer survivors, >or=2 years after diagnosis. Construct validity was assessed by comparing factor-based scale means by demographic and treatment characteristics, and correlating scales with psychosocial and health-related QOL scales. RESULTS: Factor analysis revealed four factors measuring the IOC on caregiving and finances, exercise and diet behaviors, social and emotional functioning, and religiosity. Scale scores differed by demographic and treatment characteristics according to expectations, and the pattern of correlations with psychosocial and health-related QOL generally supported the construct validity of the scales. CONCLUSION: Including the BCIA with measures of QOL, symptoms, and functioning will allow researchers to gain a more comprehensive assessment of the biopsychosocial IOC in survivors.     

Breast cancer survivors: Psychosocial concerns and quality of life

Purpose To describe the psychosocial concerns and quality of life of breast cancer survivors evaluated 2 and 3 years after primary treatment.Methods A sample of 139 breast cancer survivors who had been interviewed during the first year after primary treatment participated in a mailed survey at 2 years (N = 69) and 3 years (N = 70) after initial surgery. A random sample of these survivors were also interviewed in person. The mailed questionnaire included standardized instruments to assess quality of life (QL), rehabilitation needs, and psychological distress. Additional survey questions were developed to examine post-surgical recovery, employment and insurance problems. social support, and existential concerns. The in-person interviews expanded on these questions and systematically compared these patients' rehabilitation needs to those which existed at the time of an interview 1 year after surgery.Results The 2 and 3 year participants in this follow-up study did not differ from each other on their prior assessments with standardized QL instruments during the first year after surgery, nor did they differ from the full study sample of 227 women. The scores on the Profile of Mood States and the Functional Living Index-Cancer were the same for the 2 and 3 year survivor groups and did not differ from the previous assessments at 1 year after initial treatment. The scores on the Cancer Rehabilitation Evaluation System showed a significant decline in Global Quality of Life, Sexual Functioning and Marital Functioning between the 1 year and 3 year evaluations. For the 2 year sample only Sexual Functioning showed a deterioration between the 1 and 2 year evaluations. Using the RAND 36-Item Health Survey 1.0, the breast cancer survivors were compared with patients from the Medical Outcomes Study. The breast cancer survivors demonstrated higher levels of functioning in many dimensions (role functioning, social functioning, pain, and general health) than the patients with chronic medical conditions. In spite of relatively good physical and emotional functioning on this generic measure of health status and quality of life, these breast cancer survivors reported a number of important and severe rehabilitation problems that persisted beyond one year after primary treatment. Especially frequent were problems associated with physical and recreational activities, body image, sexual interest, sexual function, and problems with dating for those who were single.Conclusions Breast cancer survivors appear to attain maximum recovery from the physical and psychological trauma of cancer treatment by one year after surgery. A number of aspects of QL and rehabilitation problems worsen after that time. Nevertheless, breast cancer survivors rate their QL more favorably than outpatients with other common medical conditions, and they identify many positive aspects from the cancer experience.     

Psychometric properties of a tool for measuring hormone-related symptoms in breast cancer survivors

Hormone-related symptoms are common in breast cancer survivors and many aspects of these symptoms are currently under study. Reliable and valid assessment tools are needed to successfully study hormone-related symptoms in breast cancer survivors; however, no gold standard currently exists for measuring these symptoms. This study evaluated the psychometric properties of a shortened version of the Breast Cancer Prevention Trial (BCPT) symptom checklist in a sample of 803 breast cancer survivors. Principal factor analysis with Promax oblique rotation revealed a five-factor structure, identifying five separate hormone-related symptoms scales: vasomotor symptoms, urinary incontinence, cognitive/mood changes, vaginal symptoms, and weight gain/appearance concern. Hormone-related symptom scale scores differed by demographic and clinical characteristics according to expectations, suggesting that these five scales from the shortened BCPT checklist are reasonably reliable and valid. Symptom scale scores were only weakly correlated with health-related quality of life scores; however, the pattern of results generally supported the validity of the symptom scales. This study adds to the evidence that breast cancer survivors experience a significant number of hormone-related symptoms. Future clinical trials and quality of life and symptom management intervention studies would benefit from accurate assessment of hormone-related symptoms with the five scales from the shortened BCPT checklist.     

Comparison of breast and rectal cancer patients' quality of life: results of a four year prospective field study

This paper compares quality of life in breast and rectal cancer patients. The Munich Cancer Registry records clinical details of all cancer patients in the region. Over a 2-year period, cooperating clinicians recruited patients who were sent quality of life questionnaires, including the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire – C30 over 4 years. Breast cancer patients were compared to both male and female rectal cancer patients. A total of 1315 patients returned questionnaires (988 breast cancer, 327 rectal cancer). More breast cancer patients were under 70 years old, received adjuvant therapy, had a good prognosis, took medication and rated psychological support as important. Breast cancer patients reported poorer quality of life than rectal cancer patients in more than half the variables. In particular, they suffered significantly worse emotional functioning, fatigue, pain and sleeplessness. Female rectal cancer patients did not suffer the same problems. Both age groups and those with or without adjuvant therapy indicated the same trend, with breast cancer patients reporting lower scores. Breast cancer patients, despite better prognoses, appear to suffer more psychological problems than rectal cancer patients. Gender, age and therapy did not seem to explain these differences. The negative public perception of breast cancer may play a role.     

Meta-analysis of the effects of exercise intervention on quality of life in breast cancer survivors

Breast cancer is the most common type of cancer among women worldwide. Diagnosis and treatment of breast cancer pose an array of physical and psychological threats to the survivors. Exercise interventions may be particularly appropriate for cancer survivors because they have the potential to improve physical and psychological functioning. The review aims to examine the effectiveness of exercise intervention on the quality of life (QOL) of breast cancer survivors. Five databases (Medline, CINAHL, Scopus, The Cochrane Library, and CAJ Full-text Database) were searched from 2003 to July 2013. Clinical controlled trials of exercise interventions for breast cancer survivors who were at least 18 years old and had completed active cancer treatment were included. A total of 25 trials were included in this study, of which 19 were pooled together statistically. Subjects in the exercise interventions had higher overall QOL than subjects in the control group. The standardized mean difference (SMD) for changes in overall general QOL scores was 0.70 (95 % CI 0.21, 1.19). The SMD for changes in cancer-specific QOL scores was 0.38 (95 % CI 0.03, 0.74). For cancer-specific QOL domains, there were positive but non-significant trends in two QOL domains (breast symptoms: Z score = 1.12, p = 0.26; arm symptoms: Z score = 1.32, p = 0.19). This study provides updated findings supporting the idea that exercise interventions have statistically significant effects on overall QOL in breast cancer survivors, as well as positive trends for cancer site-specific QOL domains (breast and arm symptoms).     

Effects of Sexual Rehabilitation Using the PLISSIT Model on Quality of Sexual Life and Sexual Functioning in Post-Mastectomy Breast Cancer Survivors

Background and Objectives: As one of the most common treatments for breast cancer, mastectomy has adverse effects on the quality of sexual life and sexual functioning in the impacted women. Various strategies have therefore been proposed to resolve their sexual problems. The present study was conducted to determine the effect of sexual rehabilitation using the PLISSIT model in post-mastectomy breast cancer survivors. Materials and Methods: The present quasi-experimental study was conducted on a population of post-mastectomy breast cancer survivors and their husbands. Sample size was calculated as 50 each for intervention and non-intervention groups. The former received sexual counseling based on the PLISSIT model consisting of four levels of intervention: permission, limited information, specific suggestion and intensive therapy, presented in four 90-minute sessions. Data were collected using the Sexual Quality of Life-Female (SQOL-F) questionnaire and the Female Sexual Function Index (FSFI). Results: No significant differences were observed in the mean quality of sexual life scores between the intervention and control groups (P>0.05) before the intervention; however, a significant difference emerged between the groups after the intervention (P<0.01). Thus the mean score for sexual functioning in the intervention group was 26.3±3.76 before and30.0±4.38 after the intervention (P<0.0001). In the control group, however, the difference between the pre- and post-intervention mean scores was not statistically significant (P=0.713). Conclusion: The present study showed that nurses can use the PLISSIT model in conjunction with chemotherapy and radiotherapy to teach coping and problem-solving skills to women with breast cancer and their husbands and to encourage their participation in group programs for expressing their feelings and attitudes about their current sex life and thus help enhance quality of sexual life and sexual functioning in this group.     

Cognitive and Psychological Factors Associated with Early Posttreatment Functional Outcomes in Breast Cancer Survivors

Breast cancer survivors experience cognitive difficulties following chemotherapy, yet the effects of these deficits on functional outcomes have not been systematically evaluated. This study assessed the relationships between postchemotherapy cognitive difficulties and functional outcomes. Forty-six women with breast cancer were seen at 1-month postchemotherapy; data were collected on cognitive functioning, psychological variables, and physical symptoms. Wilcoxon signed-rank analyses revealed cognitive deficits in executive functioning and verbal fluency. Subsequent regression analyses demonstrated that poorer executive functioning was associated with decreased productivity, community involvement, and social role functioning. Poorer quality of life was predicted by depression and reluctance to seek social support, but not cognitive functioning. These findings indicate that executive functioning deficits are associated with important functional outcomes among breast cancer survivors 1-month postchemotherapy. Thus, treatment efforts should focus on addressing cognitive, as well as psychological and physical, issues among cancer survivors.     

Determinants of chronic fatigue in disease-free breast cancer patients: a cross-sectional study.

BACKGROUND: Quality of life after cancer treatment becomes more important as the number of long-term survivors increases. This study aimed to investigate complaints of fatigue after treatment for breast cancer. PATIENTS AND METHODS: The study patients were 150 women who had finished curative treatment for breast cancer by a mean of 29 months before commencement of this study. Measurements included computerised questionnaires and a daily Self-Observation List. RESULTS: Thirty-eight per cent of the sample were severely fatigued, compared with 11% in a matched sample of women without a history of cancer. No association was found between fatigue and former treatment. The 'severely fatigued disease-free breast cancer patient' scored more 'problematic' on psychological well-being, functional impairment, sleep disturbance, physical activity, social support, neuropsychological and social functioning compared with the 'non-severely fatigued disease-free breast cancer patient'. Furthermore, the severely fatigued patients had a lower sense of control with respect to their fatigue complaints and stronger breast cancer- and psychologically-related attributions with regard to the causes of fatigue compared with the non-severely fatigued patients. Regression analyses indicated that sleep disturbance, physical activity and causal attributions contributed significantly to the subjective experience of fatigue. CONCLUSIONS: Severe fatigue is a problem for almost 40% of the sample of breast cancer survivors. Severe fatigue is related to physical, psychological, social, cognitive and behavioural factors.     

Exercise in patients coping with breast cancer: An overview

Breast cancer is the most common type of cancer in women, but fortunately has high survival rates. Many studies have been performed to investigate the effects of exercise in patients diagnosed with breast cancer. There is evidence that exercise after the diagnosis of breast cancer improves mortality, morbidity, health related quality of life, fatigue, physical functioning, muscle strength, and emotional wellbeing. Based on scientific data, breast cancer patients should be recommended to participate in rehabilitation programs including aerobic and strength training. The aim of this article is to review the recently published data on the effect of exercise in patients with breast cancer in order to present the current perspective on the topic.     

Prevalence of Depression in Breast Cancer Survivors: a Systematic Review of Observational Studies

Background: Depression is common in breast cancer patients. The aim of this paper was to make a systematicreview of its prevalence and associated factors oin breast cancer survivors. Materials and Methods: An extensivesystematic electronic review (PUBMED, CINAHL, PsyINFO and Ovid) and handsearch were carried out toretrieve published articles up to November 2012, using Depression OR Dysthymia AND (Cancer OR Tumor ORNeoplasms as the keywords. Information about the design of the studies, measuring scale, characteristics of theparticipants, prevalence of depression and its associated factors from the included studies were extracted andsummarized. Results: We identified 32 eligible studies that recruited 10,826 breast cancer survivors. Most werecross-sectional or prospective designed. The most frequent instrument used to screen depression was the Centerfor Epidemiological Studies for Depression (CES-D, n=11 studies) followed by the Beck Depression Inventory(BDI, n=6 studies) and the Hospital Anxiety and Depression Scale (HADS, n=6 studies). CES-D returned aboutsimilar prevalence of depression (median=22%, range=13-56%) with BDI (median=22%, range=17-48%) buthigher than HADS (median=10%, range=1-22%). Depression was associated with several socio-demographicvariables, cancer-related factors, treatment-related factors, subject psychological factors, lifestyle factors, socialsupport and quality of life. Conclusions: Breast cancer survivors are at risk for depression so that detection ofassociated factors is important in clinical practice.     

Response shift effects of quality of life assessments in breast cancer survivors

Measurements of quality of life (QoL) can be distorted by respondents adapting to new situations between measurement points and consequently having a changed frame of reference. To investigate this bias in breast cancer survivors, we compare their QoL with that of the general population and use two complementary methods for detecting this bias. Breast cancer survivors (n = 308, response rate: 91%) were tested with the QoL questionnaire European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30. Response shift was examined with the thentest (retrospective judgements) and with the structural equation modelling (SEM) approach. Compared with the general population, breast cancer survivors showed impaired QoL in all functioning scales (Hedges’ g: ?0.56 to ?0.93) and symptom scales (Hedges’ g: 0.28–0.74).The thentest method indicated recalibration effects in several dimensions including social functioning. The SEM method detected a non‐uniform recalibration effect for social functioning from pretest to posttest and from pretest to thentest, but no effect between thentest and posttest. Breast cancer survivors’ QoL is clearly diminished. Comparing the two approaches for detecting response shift showed that it is also useful to apply SEM to retrospective judgements and that this can reveal response shift effects that would otherwise be overlooked.
