Validación de dos versiones cortas de la escala para depresión del Centro de Estudios Epidemiológicos en adolescentes colombianos

ObjectiveTo establish the validity and reliability of a Brief and Ultra-short Center for Epidemiological Studies Depression (CES-D) Scale in adolescents.DesignValidation study.SettingSecondary schools in Bucaramanga, Colombia.ParticipantsA total of 474 students were selected through a three stage process; 68 did not agree to participate, 8 were excluded and 8 did not complete the process.Main measurementsAdolescent students were evaluated with CES-D and the clinical interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition. The CES-D scale was re-applied 3 to 28 days after the first application. The ten items and the three items with the highest correlation with total score were selected to construct a Brief scale and Ultra-short scale, respectively. Construct validity, criterion validity, test-retest reliability and internal consistency were analyzed.ResultsFor the Brief CES-D Scale the Cronbach's alpha was 0.86 and Lin's coefficient was 0.77. The area under ROC curve was 0.83, with a sensitivity of 77.8%; specificity 74.1%. Two main factors were identified to explain the 55.81% variance. For the Ultra-short Scale the Cronbach's alpha was 0.76 and Lin's coefficient was 0.74. The area under ROC curve was 0.80, with a sensitivity of 75.56%; specificity 70.67%. One main factor was identified to explain the 68.19% of variance.ConclusionsThe Brief and Ultra-Short CES-D Scale are as useful as the original scale for the screening of MDD in adolescents; Ultra-short CES-D Scale does not preserve the original factorial structure.

Predicting Return to Work After Low Back Injury Using the Psychosocial Risk for Occupational Disability Instrument: A Validation Study

INTRODUCTION: This paper reports on the predictive validity of a Psychosocial Risk for Occupational Disability Scale in the workers' compensation environment using a paper and pencil version of a previously validated multimethod instrument on a new, subacute sample of workers with low back pain. METHODS: A cohort longitudinal study design with a randomly selected cohort off work for 4-6 weeks was applied. The questionnaire was completed by 111 eligible workers at 4-6 weeks following injury. Return to work status data at three months was obtained from 100 workers. Sixty-four workers had returned to work (RTW) and 36 had not (NRTW). RESULTS: Stepwise backward elimination resulted in a model with these predictors: Expectations of Recovery, SF-36 Vitality, SF-36 Mental Health, and Waddell Symptoms. The correct classification of RTW/NRTW was 79%, with sensitivity (NRTW) of 61% and specificity (RTW) of 89%. The area under the ROC curve was 84%. CONCLUSIONS: New evidence for predictive validity for the Psychosocial Risk-for-Disability Instrument was provided. IMPLICATIONS: The instrument can be useful and practical for prediction of return to work outcomes in the subacute stage after low back injury in the workers' compensation context.     

Depressive symptoms and condom use with clients among female sex workers in China

This study examines the association between depressive symptoms and condom use with clients among 278 female sex workers (FSW) in Guangxi, China. About 62% of these FSW had a high level of depressive symptoms (CES-D total score >or=16). Multiple logistic regression analyses indicated that FSW with high level of depressive symptoms were less likely to use condoms consistently (aOR = 0.50, 95% CI: 0.28-0.89) or use condoms properly (aOR = 0.44, 95% CI: 0.20-0.99). The findings suggested that HIV prevention programs targeted at FSW should take into consideration the level of depression they experience.

Test of item-response bias in the CES-D scale. experience from the New Haven EPESE study

We present results of item-response bias analyses of the exogenous variables age, gender, and race for all items from the Center for Epidemiologic Studies Depression (CES-D) scale using data (N = 2340) from the New Haven component of the Established Populations for Epidemiologic Studies of the Elderly (EPESE). The proportional odds of blacks responding higher on the CES-D items "people are unfriendly" and "people dislike me" were 2.29 (95% confidence interval: 1.74, 3.02) and 2.96 (95% confidence interval: 2.15, 4.07) times that of whites matched on overall depressive symptoms, respectively. In addition, the proportional odds of women responding higher on the CES-D item "crying spells" were 2.14 (95% confidence interval: 1.60, 2.82) times that of men matched on overall depressive symptoms. Our data indicate the CES-D would have greater validity among this diverse group of older men and women after removal of the crying item and two interpersonal items.     

Associations of health behaviors on depressive symptoms among employed men in Japan

The associations between health behaviors and depressive symptoms have been demonstrated in many studies. However, job strain has also been associated with health behaviors. The aim of this study was to analyze whether health behaviors such as physical activity, sleeping, smoking and alcohol intake are associated with depressive symptoms after adjusting for job strain. Workers were recruited from nine companies and factories located in east and central areas of Japan. The Center for Epidemiologic Studies Depression (CES-D) Scale was used to assess depressive symptoms. Psychological demand and control (decision-latitude) at work were measured with the Job Content Questionnaire. Multiple logistic regression analysis was used to determine the independent contribution of each health behavior to depressive symptoms. Among the total participants, 3,748 (22.7%) had depressive symptoms, which was defined as scoring 16 or higher on the CES-D scale. Using the multiple logistic regression analysis, depressive symptoms were significantly associated with physical activity less than once a week (adjusted relative risk [ARR] = 1.18, 95% confidence interval [CI], 1.14 to 1.25) and daily hours of sleep of 6 h or less (ARR, 1.25; 95% CI, 1.14 to 1.35). Smoking and frequency of alcohol intake were not significantly associated with depressive symptoms. This study suggests some health behaviors such as physical activity or daily hours of sleep are associated with depressive symptoms after adjusting for job strain.     

Validation of the Patient Health Questionnaire-9 for Major Depressive Disorder in the Occupational Health Setting

Purpose Because of the increased risk of long-term sickness leave for employees with a major depressive disorder (MDD), it is important for occupational health professionals to recognize depression in a timely manner. The Patient Health Questionnaire-9 (PHQ-9) has proven to be a reliable and valid instrument for screening MDD, but has not been validated in the occupational health setting. The aim of this study was to validate the PHQ-9 for MDD within a population of employees on sickness leave by using the MINI-International Neuropsychiatric Interview (MINI) as a gold standard. Methods Participants were recruited in collaboration with the occupational health service. The study sample consisted of 170 employees on sickness leave between 4 and 26 weeks who completed the PHQ-9 and were evaluated with the MINI by telephone. Sensitivity, specificity, positive and negative predictive value, efficiency and 95 % confidence intervals (95 % CIs) were calculated for all possible cut-off values. A receiver operator characteristics (ROC) analysis was computed for PHQ-9 score versus the MINI. Results The optimal cut-off value of the PHQ-9 was 10. This resulted in a sensitivity of 86.1 % [95 % CI (69.7–94.8)] and a specificity of 78.4 % [95 % CI (70.2–84.8)]. Based on the ROC analysis, the area under the curve for the PHQ-9 was 0.90 [SE = 0.02; 95 % CI (0.85–0.94)]. Conclusion The PHQ-9 shows good sensitivity and specificity as a screener for MDD within a population of employees on sickness leave.     

Psychometric properties of the Center for Epidemiologic Studies Depression Scale (CES-D) in French clinical and nonclinical adults

BackgroundPrevious research on the Center for Epidemiologic Studies Depression Scale (CES-D) has five main limitations. First, no study provided evidence of the factorial equivalence of this instrument across samples of depressive and community participants. Second, only one study included systematic tests of measurement invariance based on confirmatory factor analyses (CFA), and this study did not consider the higher-order factor structure of depression, although it is the CES-D global scale score that is most often used in the context of epidemiological studies. Third, few studies investigated the screening properties of the CES-D in non-English-language samples and their results were inconsistent. Fourth, although the French version of the CES-D has been used in several previous studies, it has never been systematically validated among community and/or depressed adults. Finally, very few studies have taken into account the ordered-categorical nature of the CES-D answer scale. The purpose of the study reported herein was therefore to examine the construct validity (i.e., factorial, reliability, measurement invariance, latent mean invariance, convergence, and screening properties) of the CES-D in a French sample of depressed patients and community adults.MethodsA total sample of 469 participants, comprising 163 clinically depressed patients and 306 community adults, was involved in this study. The factorial validity, and the measurement and latent mean invariance of the CES-D across gender and clinical status, were verified through CFAs based on ordered-categorical items. Correlation and receiver operator characteristic curves were also used to test the convergent validity and screening properties of the CES-D.ResultsThe present results: (i) provided support for the factor validity and reliability of a second-order measurement model of depression based on responses to the CES-D items; (ii) revealed the full measurement invariance of the first- and second-order measurement models across gender; (iii) showed the partial strict measurement invariance (four uniquenesses had to be freely estimated, but the factor variance–covariance matrix also proved fully invariant) of the first-order factor model and the complete measurement invariance of the second-order model across patients and community adults; (iv) revealed a lack of latent mean invariance across gender and across clinical and community subsamples (with women and patients reporting higher scores on all subscales and on the full scale); (v) confirmed the convergent validity of the CES-D with measures of depression, self-esteem, anxiety, and hopelessness; and (vi) demonstrated the efficacy of the screening properties of this instrument among clinical and nonclinical adults.ConclusionThis instrument may be useful for assessing depressive symptoms or for the screening of depressive disorders in the context of epidemiological studies targeting French patients and community men and women with a background similar to those from the present study.     

Green Tea Consumption and Depressive Symptoms among Japanese Workers: The Furukawa Nutrition and Health Study

Although several cross-sectional studies have described an inverse association between green tea consumption and depressive symptoms, only one study has prospectively investigated this association. We investigated the cross-sectional and prospective associations between green tea consumption and depressive symptoms in a working population in Japan. Participants were 1987 workers who participated in the baseline survey for a cross-sectional association, and 916 participants who did not have depressive symptoms at baseline who responded to both the baseline and follow-up surveys for a prospective association. Green tea consumption was evaluated with a validated self-administered diet history questionnaire. Depression symptoms were evaluated with the Center for Epidemiologic Studies Depression (CES-D) scale. Multiple logistic regression was conducted to estimate the odds ratio of depressive symptoms based on green tea consumption. In the cross-sectional analysis, green tea consumption was not associated with the prevalence of depression symptoms. Moreover, consumption at baseline was not associated with depression symptoms after 3 years; the multivariable-adjusted odds ratio of depressive symptoms for ≥2 cups/day of green tea was 1.12 (95% confidence interval 0.65–1.91) compared with <4 cups/week after adjustment for covariates including dietary factors (trend p = 0.67). Our results suggest that there is no association of consumption of green tea with symptoms of depression in Japanese.     

Prevalence,Stability, and Socio-Demographic Correlates of Depressive Symptoms in Black Mothers During the First 18 Months Postpartum

Objectives: The goals of this longitudinal study were to evaluate 1) the prevalence and stability of high depressive symptom levels during the first 18 months postpartum in a sample of otherwise healthy Black mothers varying in socio-economic status and 2) the relation of socio-demographic variables and level of socio-demographic risk to maternal depressive symptom levels during this time period. Methods: Participants were 163 Black adult mothers of healthy, full-term infants. The level of mothers' depressive symptomatology was assessed at 2, 3, 6, 12, and 18 months postpartum using the Center for Epidemiological Studies-Depression Scale (CES-D). Mothers provided socio-demographic information at each assessment. Univariate and bivariate analyses were used to analyze the data. Results: The percentage of mothers with an elevated CES-D score (16 or higher) at single visits ranged from 13.5 to 14.7%, and 35.0% had at least one elevated CES-D score by 18 months postpartum. CES-D total scores were significantly correlated across each pair of visits (mean r = 0.57, all p's < 0.0001), and average CES-D scores did not change significantly over time. Single marital status, low-income status, and more negative maternal perceptions of the adequacy of income for meeting familial needs were significantly related to higher maternal CES-D scores at each assessment (all p's < 0.05). Level of socio-demographic risk, as assessed with a composite risk score derived from these variables, was significantly related to higher average CES-D scores (averaged across visits) (p < 0.0001) and to a greater frequency of elevated CES-D scores (16 or higher) during the first 18 months postpartum (p = 0.0002). Conclusions: The prevalence and stability of high levels of maternal depressive symptomatology during the first 18 months postpartum in this sample of Black women are consistent with those reported in prior studies of community samples of mothers unselected for race. Mothers with higher socio-demographic risk profiles had higher levels of maternal depressive symptoms at each assessment point.     

A population-based longitudinal study on work environmental factors and the risk of major depressive disorder

To investigate the relation between work environmental factors and the risk of major depressive disorder (MDD) over 1 year, the authors conducted a population-based longitudinal study of randomly selected employees in Alberta, Canada (January 2008 to November 2011). Participants without a current or lifetime diagnosis of MDD at baseline (n = 2,752) were followed for 1 year. MDD was assessed using the World Health Organization's Composite International Diagnostic Interview-Auto 2.1. The overall 1-year incidence of MDD was 3.6% (95% confidence interval: 2.8, 4.6); it was 2.9% (95% confidence interval: 1.9, 4.2) in men and 4.5% (95% confidence interval: 3.3, 6.2) in women. The relations between work environmental factors and MDD differed by sex. In men, high job strain increased the risk of MDD in those who worked 35-40 hours per week; job insecurity and family-to-work conflict were predictive of MDD. Women who worked 35-40 hours per week and reported job insecurity, a high effort-reward imbalance, and work-to-family conflict were at a higher risk of developing MDD. Job strain, effort-reward imbalance, job insecurity, and work-to-family conflicts are important risk factors for the onset of MDD and should be targets of primary prevention. However, these work environmental factors appear to operate differently in men and in women.     

Effects of physical exercise on depression, neuroendocrine stress hormones and physiological fitness in adolescent females with depressive symptoms

BACKGROUND: Regular physical exercise may improve a variety of physiological and psychological factors in depressive persons. However, there is little experimental evidence to support this assumption for adolescent populations. We conducted a randomized controlled trial to investigate the effect of physical exercise on depressive state, the excretions of stress hormones and physiological fitness variables in adolescent females with depressive symptoms. METHODS: Forty-nine female volunteers (aged 18-20 years; mean 18.8 +/- 0.7 years) with mild-to-moderate depressive symptoms, as measured by the Centre for Epidemiologic Studies Depression (CES-D) scale, were randomly assigned to either an exercise regimen or usual daily activities for 8 weeks. The subjects were then crossed over to the alternate regimen for an additional 8-week period. The exercise program consisted of five 50-min sessions per week of a group jogging training at a mild intensity. The variables measured were CES-D rating scale, urinary cortisol and epinephrine levels, and cardiorespiratory factors at rest and during exercise endurance test. RESULTS: After the sessions of exercise the CES-D total depressive score showed a significant decrease, whereas no effect was observed after the period of usual daily activities (ANOVA). Twenty-four hour excretions of cortisol and epinephrine in urine were reduced due to the exercise regimen. The training group had a significantly reduced resting heart rate and increased peak oxygen uptake and lung capacity. CONCLUSIONS: The findings of this study suggest that a group jogging exercise may be effective in improving depressive state, hormonal response to stress and physiological fitness of adolescent females with depressive symptoms.     

Summed score of the Patient Health Questionnaire-9 was a reliable and valid method for depression screening in chronically ill elderly patients

OBJECTIVE: To assess the psychometric properties of the Patient Health Questionnaire-9 (PHQ-9) as a screening instrument for depression in elderly patients with diabetes mellitus (DM) and chronic obstructive pulmonary disease (COPD) without known depression. STUDY DESIGN AND SETTING: DM and COPD patients aged >59 years were selected from general practices. A test-retest was conducted in 105 patients. Criterion validity, using the Mini International Neuropsychiatric Interview psychiatric interview to diagnose major depressive disorder (MDD) and any depressive disorder (ADD) as diagnostic standard, was evaluated for both summed and algorithm-based PHQ-9 score in 713 patients. Correlations with quality of life and severity of illness were calculated to assess construct validity. RESULTS: Cohen's kappa for the algorithm-based score was 0.71 for MDD and 0.69 for ADD. Correlation for test-retest assessment of the summed score was 0.91. The algorithm-based score had low sensitivity and high specificity, but both sensitivity and specificity were high for the optimal cut-off point of 6 on the summed score for ADD (Se 95.6%, Sp 81.0%). Correlations between summed score and quality of life and severity of illness were acceptable. CONCLUSION: The summed PHQ-9 score seems a valid and reliable screening instrument for depression in elderly primary care patients with DM and COPD.     

Depressive symptoms and self-reported occupational injury in small and medium-sized companies

Objectives  This survey was designed to determine whether depressive symptoms had an effect on the risk of self-reported occupational injury in South Korea. Methods  We conducted a prospective follow-up survey of workers at 44 small- to medium-sized companies classified into manufacturing or service businesses; 1,350 questionnaires were used in the final analysis. The first survey requested information regarding personal characteristics, work characteristics, and depressive symptoms (CES-D); the second survey queried participants in the first survey about self-reported occupational injuries (including minor scratches or cuts) experienced in the previous 4 months. Risk ratios (RRs) were calculated through Poisson regression analysis. The number of occupational injuries during the previous 4 months served as the dependent variable, and depressive symptoms served as the independent variable. Results  After adjustment for demographic factors, the RRs were 1.75 (95% CI: 1.41–2.18) and 2.68 (95% CI: 1.98–3.64) in male and female, respectively. Additional adjustment for work-related variables did not alter the RR considerably in females (2.65; 95% CI: 1.95–3.59). Among the male workers, however, the RR was not significant (1.21; 95% CI: 0.95–1.55). On the other hand, when the analysis was limited to blue-collar workers, after adjustment for demographic and work-related factors, the RRs remained significant in both genders (male: 1.34; 95% CI: 1.03–1.74; female: 2.04; 95% CI: 1.41–2.95). Conclusions  We found that the risk of self-reported occupational injury experience was higher in workers who reported depressive symptoms. Additional study using objective data is required to confirm our results.     

Intimate Partner Violence/Abuse and Depressive Symptoms among Female Health Care Workers: Longitudinal Findings

Intimate partner violence and abuse (IPV/A) have been shown to have a major impact on mental health functioning. This study assessed the longitudinal association between recent IPV/A and depressive symptoms to identify potential targets for preventive interventions for women. Random effects models were used to examine four waves of data collected at 6-month intervals from a cohort of 1,438 female health care workers. IPV/A (e.g., sexual and physical violence, psychological abuse) in the past 5 years was associated with higher Center for Epidemiologic Studies Depression Scale (CES-D) 10 scores across four waves after adjustment for age, time, marital status, and childhood trauma. Women who reported IPV/A in the past 5 years had higher CES-D 10 scores (β, 1.31; 95% confidence interval, 0.79–1.82; p < .0001) than nonabused women. This association was generally constant with time, suggestive of a cross-sectional association across all four waves of data. Additionally, recent IPV/A was associated with change in depressive symptoms over time among the full cohort and those with CES-D 10 scores below 10 (the threshold for likely depression) at baseline. Recent IPV/A was independently associated with depressive symptoms both cross-sectionally and longitudinally. The longitudinal association was stronger among those not depressed at baseline. Implications for health care settings and workplace policies addressing IPV/A are discussed.     

Maternal prenatal depressive symptoms and spontaneous preterm births among African-American women in Baltimore,Maryland

The purpose of this study was to examine the relation between maternal depressive symptoms and spontaneous preterm birth. From 1991 to 1993, pregnant, African-American women were prospectively enrolled at four hospital-based clinics in Baltimore, Maryland, that serve low-income areas of the city. The Center for Epidemiologic Studies Depression (CES-D) Scale was used to assess depressive symptoms. Multiple logistic regression analysis estimated the independent contribution of maternal depressive symptoms to spontaneous preterm birth, controlling for behavioral, clinical, and demographic variables. Among the 1,399 women in the sample, 117 (8.4%) had a spontaneous preterm delivery. Spontaneous preterm birth occurred among 12.7% of those with a CES-D score in the upper 10th percentile and among 8.0% of those with a lower score (relative risk = 1.59). The adjusted odds ratio for an elevated CES-D score was 1.96 (95% confidence interval: 1.04, 3.72); hence, maternal depressive symptoms in this sample of African-American women were independently associated with spontaneous preterm birth. Effective treatment of depression in pregnant women could ultimately result in a reduction of spontaneous preterm births.     

An examination of depression through the lens of spinal cord injury: Comparative prevalence rates and severity in women and men

PURPOSE: This study describes the prevalence of probable major depressive disorder (MDD) as well as other depressive disorders (ODD) and severity of depressive symptoms in a national sample of women with spinal cord injury (SCI) and compares them with a case-matched sample of men with SCI. METHODS: A sample of 585 women was drawn and case-matched with men from the SCI Model System National SCI Database according to level/completeness of injury, follow-up year, and age. The outcome measure of depression was the Patient Health Questionnaire. MAIN FINDINGS: Prevalence rates for women were 7.9% for probable MDD and 9.7% for ODD; rates for men were 9.9% and 10.3%, respectively. Logistic regression revealed that women who were divorced or at year 1 follow-up had a higher odds of having probable MDD (odds ratio [OR], 3.4 and 2.9, respectively). Employed women and men had significantly lower odds of probable MDD (OR, 0.274 and 0.358, respectively). Statistically significant differences were not found in gender comparisons for either probable MDD or symptom severity, which also were not associated with injury characteristics. CONCLUSION: The most significant, and unexpected, research finding is the absence of gender differences in probable MDD and symptom severity. Results challenge notions that depression will necessarily follow SCI; that injury characteristics determine the development and severity of depression; and that women experience a greater burden of depression than men. The main clinical implication is that depression screening and referral should be a routine feature of health care for women living with SCI, as well as for their male counterparts. Furthermore, nearly one fourth of women and men reported experiencing some or greater difficulty in daily life and relationships in the absence of probable depressive disorder, warranting monitoring of subsyndromal depression as well.     

Depressive symptoms during pregnancy in relation to fish consumption and intake of n-3 polyunsaturated fatty acids

An inverse association between depression and the n-3 fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), primarily obtained from fish consumption, is observed in both observational and experimental research and is biologically plausible. Study objectives were to examine whether prenatal depressive symptoms were associated with lower intakes of fish or EPA+DHA. Pregnant women (n = 2394) completed a telephone interview between 10 and 22 weeks' gestation in London, Ontario, 2002-05. Depressive symptoms were measured using the Center for Epidemiologic Studies - Depression Scale (CES-D). Intakes of fish and EPA+DHA were measured using a validated food-frequency questionnaire. Sequential multiple regression was used to examine associations of depressive symptoms with intake of fish and EPA+DHA, respectively, while controlling for sociodemographic, health and lifestyle variables. The mean CES-D score was 9.9 (SD 8.0). Intake of EPA+DHA was dichotomised at the median value of 85 mg/day. Fish consumption and intake of EPA+DHA were not associated with prenatal depressive symptoms after adjustment for confounders; however, depressive symptoms were significantly higher for lower intakes of EPA+DHA among current smokers and women of single/separated/divorced marital status. The adjusted difference in CES-D scores between intake categories of EPA+DHA was -2.4 [95% CI -4.2, -0.4] for current smokers and -2.8 [95% CI -5.2, -0.4] for women of single marital status. Although pregnant women may be at risk for low concentrations of EPA and DHA, an association between low intakes of EPA+DHA and increased depressive symptoms was only observed among current smokers and women of single marital status.     

Racial disparities in elevated prenatal depressive symptoms among black and white women in eastern north Carolina

PURPOSE: Black women have an increased risk for preterm birth compared with white women, and prior research indicated that maternal prenatal depressive symptoms are associated with increased risk for preterm outcomes among black women. Race-related differences in prenatal depression could be of etiologic significance in understanding racial disparities in preterm birth. Our study focused on Center for Epidemiologic Studies' Depression Scale (CES-D) scores of pregnant black and white women. METHODS: Women were administered the CES-D at the time of their first visit to hospital-based prenatal clinics. Two cutoff scores for the CES-D were used: 16 or higher, which indicates "significant" depressive symptoms, and 23 or higher, which indicates major depressive disorder. RESULTS: For the sample of 1163 women, mean CES-D scores were significantly higher among black (17.4) than white (13.7) women. Of black women, 49% had CES-D scores higher than 15 compared with 33.5% of white women. Also, 27.5% of black women had scores higher than 22 compared with 16% of white women. After adjustment for maternal age, marital status, and education, odds ratios for race for both CES-D cutoff scores were approximately 1.5. CONCLUSIONS: Results of this study indicate that black women have greater rates of prenatal depression than white women.
