The Broad Autism Phenotype-International Test (BAP-IT): A two-domain-based test for the assessment of the broad autism phenotype

LAY ABSTRACT

The broad autism phenotype refers to a group of behaviors related to autism spectrum disorder, but that appear to a lesser extent. Its assessment has been performed through outdated broad autism phenotype/autism spectrum disorder definitions and tests. To address this problem, this study presents the development of a new test, the Broad Autism Phenotype-International Test, a 20-item measure consisting of two dimensions, SOCIAL-BAP and RIRE-BAP, targeting the two-domain operationalization of autism spectrum disorder in Spain and the United Kingdom. Unlike the Broad Autism Phenotype Questionnaire, this test received empirical support as a quick and effective broad autism phenotype measure that can facilitate both broad autism phenotype/autism spectrum disorder research and interventions. This is the first step to studying the BAP in several Spanish and English-speaking countries.

Sociodemographic Factors, Health-Risk Behaviors, and Chronic Conditions Are Associated with a High Prevalence of Depressive Symptoms: Findings from the Indonesian Family Life Survey-5

Depression is a significant public health challenge. However, limited research exists regarding the risk of sociodemographic factors, health-risk behavior, and chronic conditions in relation to the development of depression in Indonesia. This study assesses the prevalence of depressive symptoms in adolescents and adults, and identifies its potential associations with sociodemographic factors, health-risk behaviors, and chronic conditions. A national cross-sectional population-based survey was performed, using the Indonesian Family Life Survey (IFLS-5), to assess depressive symptoms in respondents aged 15 years and older. Depression was evaluated using the Center for Epidemiologic Studies-Depression (CES-D) scale, and potential associations with sociodemographic factors, health-risk behaviors, and chronic conditions were examined using logistic regression analysis. The study revealed a high prevalence of depressive symptoms, with the highest incidence observed in the age group of 25-34 years. Factors such as unmarried status, younger age, good physical activity, and having chronic conditions showed associations with depression. These findings have implications for developing public mental health strategies to reduce the prevalence of depression in Indonesia.

Resilience as a protective factor against depression in informal caregivers

Introduction

Although previous research has demonstrated that resilience can be protective against various mental health conditions such as depression, existing studies examining the relationship between resilience and depression have limitations. To our knowledge, the moderators of the relationship have not been examined. The aim of this study was to determine whether resilience acts as a protective factor against depression in informal caregivers and to examine potential moderators of the relationship between these variables.

Methods

In this cross-sectional study, 554 randomly selected informal caregivers participated (86.8% women, average age = 55.3 years). Major depressive episode, depressive symptomatology, resilience, positive environmental reward, negative automatic thoughts, self-efficacy, and personality were assessed.

Results

A total of 16.1% of informal caregivers met criteria for a depressive episode and 57.4% were at risk of developing depression. The average resilience score was 26.3 (SD = 7.6); 62.6% of participants were in the lower quartile of the resilience scale. The gender of the informal caregiver and self-efficacy acted as moderating variables in the relationship between resilience and depression. The impact of resilience on depressive symptoms was more pronounced in female informal caregivers, and increased as self-efficacy increased.

Discussion

Based on these findings, programs aimed at preventing depression in informal caregivers should focus on promoting resilience, especially in women, and introduce strategies to enhance self-efficacy to increase their impact.

Validation of the Spanish version of the Perceived Control Scale: Perceived Constraints on Personal Control and Perceived Mastery

OBJECTIVES

Perceived control is a relevant variable for understanding middle and older adults' mental health. The Perceived Control Scale has two dimensions, Perceived Constraints on Personal Control and Perceived Mastery, and is a widely used instrument for assessing perceived control in adults. The aim of this study was to analyze the psychometric properties of the Spanish version of the Perceived Control Scale with data from two different studies.

METHOD

In Study 1, 348 older adults between 60 and 92 years old were assessed through face-to-face assessments. In Study 2, 334 adults between 40 and 90 years completed an online survey. Perceived control, self-perceptions of aging, and anxiety and depressive symptomatology were assessed. An exploratory (Study 1) and confirmatory (Study 2) factor analysis of the Perceived Control Scale were performed, and reliability and its relationship with the other assessed variables were evaluated.

RESULTS

Results from parallel, exploratory, and confirmatory factor analyses suggested that the Spanish version of the Perceived Control Scale has a bidimensional structure: Perceived Constraints on Personal Control and Perceived Mastery. Good internal consistency was found for the scale in both samples. The results revealed negative and significant associations with negative self-perceptions of aging, and anxiety and depressive symptomatology.

CONCLUSION

The Spanish version of the Perceived Control Scale shows good psychometric properties which endorse its use with middle-aged and older adults assessed either face-to-face or through online surveys.

Efficacy of a Cognitive Behavioral Intervention for the Prevention of Depression in Nonprofessional Caregivers Administered through a Smartphone App: A Randomized Controlled Trial

Due to the limited availability of in-person interventions for caregivers, the development of effective programs that use new technologies to prevent depression is needed. The goal of this research was to assess the efficacy of a cognitive behavioral intervention for the prevention of depression, administered to nonprofessional caregivers through a smartphone application (app). One hundred and seventy-five caregivers were randomly assigned to either an app-based cognitive behavioral intervention (CBIA), the CBIA intervention plus a telephone conference call (CBIA + CC), or an attention control group (ACG). At post-intervention, the incidence of depression was lower in the CBIA and CBIA + CC compared to the ACG (1.7% and 0.0% vs. 7.9%, respectively). The absolute risk, relative risk, and number needed to treat compared to the ACG were 6.2%, 21.6%, and 16 for the CBIA, whilst they were 8%, 0.0%, and 13 for the CBIA + CC. Depressive symptomatology was significantly lower in the CBIA and CBIA + CC compared to the ACG (d = 0.84, Cliff's δ = 0.49; d = 1.56, Cliff's δ = 0.72), as well as in the CBIA + CC compared to the CBIA (d = 0.72, Cliff's δ = 0.44). The prevention of depression was more likely in participants who received the CBIA, and adding the conference call in the CBIA + CC group improved the likelihood of this.

Associations between Social Support Dimensions and Resilience Factors and Pathways of Influence in Depression and Anxiety Rates in Young Adults

Emerging adulthood is an important developmental period, associated to mental health risk. Resilience research points to both social and personal protective factors against development of psychopathology, but there is paucity with their comprehensive study in young adults. This study provides and initial integrative approach to model multiple dimensions of perceived social support (i.e., from family, friends, significant others) and personal factor of trait resilience (i.e., coping and persistence during stress, tolerance to negative affect, positive appraisals, trust) and their hypothesized contributions to reducing depression and anxiety rates. The study was conducted with a sample of 500 Spanish emerging adults (18 to 29 years old). Regression analyses and multiple mediation models were performed to test our hypotheses. Results showed that social support from family was the dimension with the highest strength relating individual differences in resilience. Furthermore, analyses supported a differential mediating role of specific resilience factors (coping and persistence during stress, tolerance to negative affect, positive appraisals, trust) in partially accounting for the association between higher social support from family and lower depression and anxiety levels in young adults. These results may inform new programs of mental health during emerging adulthood via the promotion of different sources of social support and their related resilience pathways contributing to low emotional symptomatology at this stage of development.

Factor structure of the 10-item CES-D Scale among patients with persistent COVID-19

The presence of persistent coronavirus disease 2019 (COVID-19) might be associated with significant levels of psychological distress that would meet the threshold for clinical relevance. The Center for Epidemiologic Studies Depression Scale (CES-D) version 10 has been widely used in assessing psychological distress among general and clinical populations from different cultural backgrounds. To our knowledge, however, researchers have not yet validated these findings among patients with persistent COVID-19. A cross-sectional validation study was conducted with 100 patients from the EXER-COVID project (69.8% women; mean (±standard deviation) ages: 47.4 ± 9.5 years). Confirmatory factor analyses (CFAs) were performed on the 10-item CES-D to test four model fits: (a) unidimensional model, (b) two-factor correlated model, (c) three-factor correlated model, and (d) second-order factor model. The diagonal-weighted least-squares estimator was used, as it is commonly applied to latent variable models with ordered categorical variables. The reliability indices of the 10-item CES-D in patients with persistent COVID-19 were as follows: depressive affect factor ( α Ord = 0 . 82 ${\alpha }_{\mathrm{Ord}}=0.82$ ; ω u - cat = 0 . 78 ${\omega }_{{\rm{u}}-\mathrm{cat}}=0.78$ ), somatic retardation factor ( α Ord = 0 . 78 ${\alpha }_{\mathrm{Ord}}=0.78$ ; ω u - cat = 0 . 56 ${\omega }_{{\rm{u}}-\mathrm{cat}}=0.56$ ), and positive affect factor ( α Ord = 0 . 56 ${\alpha }_{\mathrm{Ord}}=0.56$ ; ω u - cat = 0 . 55 ${\omega }_{{\rm{u}}-\mathrm{cat}}=0.55$ ). The second-order model fit showed good Omega reliability ( ω ho = 0 . 87 ${\omega }_{\mathrm{ho}}=0.87$ ). Regarding CFAs, the unidimensional-factor model shows poor goodness of fit, especially residuals analysis (root mean square error of approximation [RMSEA] = 0.081 [95% confidence interval, CI = 0.040-0.119]; standardized root mean square residual [SRMR] = 0.101). The two-factor correlated model, three-factor correlated model, and second-order factor model showed adequate goodness of fit, and the χ² difference test ( ∆ X 2 $\unicode{x02206}{X}^{2}$ ) did not show significant differences between the goodness of fit for these models ( ∆ X 2 = 4.1128 $\unicode{x02206}{X}^{2}=4.1128$ ; p = 0.127). Several indices showed a good fit with the three-factor correlated model: goodness-of-fit index = 0.974, comparative fit index = 0.990, relative noncentrality index = 0.990, and incremental fit index = 0.990, which were all above 0.95, the traditional cut-off establishing adequate fit. On the other hand, RMSEA = 0.049 (95% CI = 0.000-0.095), where an RMSEA < 0.06-0.08 indicates an adequate fit. Item loadings on the factors were statistically significant ( λ j ≥ 0.449 ${\lambda }_{j}\ge 0.449$ ; p's < 0.001), indicating that the items loaded correctly on the corresponding factors and the relationship between factors ( ϕ ≥ 0.382 $\phi \ge 0.382$ ; p's ≤ 0.001. To our knowledge, this is the first study to provide validity and reliability to 10-item CES-D in a persistent COVID-19 Spanish patient sample. The validation and reliability of this short screening tool allow us to increase the chance of obtaining complete data in a particular patient profile with increased fatigue and brain fog that limit patients' capacity to complete questionnaires.

A pilot study for a smartphone app for the prevention of depression in non-professional caregivers

OBJECTIVES

The main objective of the current study was to evaluate the feasibility and acceptability of a cognitive-behavioral prevention intervention administered through a smartphone app in non-professional caregivers with symptoms of depression. The secondary objective was to make a preliminary evaluation of its effectiveness either alone or supplemented with telephone conference calls.

METHODS

Eighty-seven participants (M_age = 51.8 years) were randomly assigned to an app-based cognitive-behavioral intervention (CBIA; n = 29), CBIA supplemented with telephone conference calls (CBIA + CC; n = 28), or an attention control group (ACG; n = 30). The participants for both interventions received five cognitive-behavioral modules through the app, and those in CBIA + CC an additional 30-minute phone call in each module.

RESULTS

3.4% of caregivers dropped out. In all groups, the number of modules completed was high. Participants completed a high percentage of the homework and were highly satisfied with both CBIA and CBIA + CC. At post-intervention, there was a lower incidence of depression and depressive symptoms for CBIA + CC compared with CBIA, and for CBIA and CBIA + CC compared with ACG.

CONCLUSION

The results supported the feasibility and acceptability of the cognitive-behavioral intervention, and demonstrated that telephone contact improves its effectiveness.

Repetitive Negative Thinking Processes Account for Gender Differences in Depression and Anxiety During Adolescence

Rumination and worry are vulnerability factors involved in the early development of depression and anxiety during adolescence, particularly in girls. Current views conceptualize rumination and worry as transdiagnostic forms of repetitive negative thinking (RNT). However, most of research has analyzed them separately, without considering gender differences. We analyzed common and specific roles of rumination and worry in accounting for depressive and anxiety symptom levels overall and as a function of gender in adolescents (N = 159). Rumination and worry items were loaded into separate RNT factors. Girls showed a higher use of rumination and worry and higher levels of depression and anxiety than boys. Structural equation modeling supported that both RNT factors accounted for gender differences in symptom levels: rumination was the strongest mediator for depression and worry the strongest mediator for anxiety. Our findings support both general and specific contributions of RNT to account for affective symptomatology during adolescence, particularly in girls.

Long-Term Effects of a Cognitive Behavioral Conference Call Intervention on Depression in Non-Professional Caregivers

Recent evidence supports the efficacy of conference call cognitive-behavioral interventions in preventing depression in caregivers at post-intervention, but we do not know whether the results are sustained long term. The main objective of this study was to evaluate the long-term efficacy of a cognitive-behavioral intervention administered by telephone conference call in preventing depression in caregivers with elevated depressive symptoms, comparing all components of the intervention versus only the behavioral ones. A randomized controlled trial was conducted using a dismantling strategy. At total of 219 caregivers were randomly assigned to a cognitive-behavioral conference call intervention (CBCC; n = 69), a behavioral-activation conference call intervention (BACC; n = 70), or a usual care control group (CG, n = 80). Information was collected on depressive symptoms and depression at pre-intervention and at 1, 3, 6, 12, and 36 months post-intervention. At 36 months, there was a reduction in depressive symptoms (p < 0.001) and a lower incidence of major depressive episodes in both the CBCC and BACC groups compared to CG (8.7%, 8.6%, and 33.7%, respectively). The results show that a conference call intervention was effective in the long term to prevent depression in caregivers and that the behavioral-activation component was comparable to the complete cognitive-behavioral protocol.

Relationship between pediatric asthma and psychosocial status of caregivers

OBJECTIVE

To determine the relationship between psychosocial caregiver disorders and childhood asthma.

STUDY DESIGN

We performed a matched case-control study with asthmatic children (6-14 years of age) from two different clinics in Zaragoza, Spain, between 2010 - 2016. Clinical data were collected from medical records and psychosocial disorders were assessed by interviewing the caregiver using validated questionnaires (Goldberg, CES-D, SF-12, PSS and SPIN). General analysis of cases and controls was performed using McNemar, Chi² and Wilcoxon nonparametric tests. A logistic regression model to predict more severe asthma, adjusted by caregiver psychosocial disorders was performed.

RESULTS

208 children were evaluated (104 cases). Mean age was 9.7 ± 2.4 years, with a male predominance (62.5%). Anxiety, social phobia, depression, acute and chronic psychological disorders, and poor quality of life related to mental health were significantly more prevalent in caregivers of asthmatic children (p<0.05). On multivariate analysis, all of the above disorders significantly increased the risk of uncontrolled asthma, where anxiety, acute psychological disorders, and chronic psychological disorders were the most significant (OR 8.54, 95%CI 3.46-21.05, p<0.001; OR 6.05, 95%CI 2.39-15.28, p<0.001; and OR 4.86, 95%CI 1.97-12.02, p=0.001, respectively).

CONCLUSION

The prevalence of psychosocial disorders in caregivers of asthmatic children is high, when compared to caregivers of healthy children. The presence of anxiety, social phobia, depression, and poor quality of life is associated with an increased risk of worse controlled asthma. Perhaps, early detection and treatment of these disorders could positively impact childhood asthma control.

Patterns of family negativity in the perinatal period: Implications for mental health among Mexican-origin women

Negativity in the family environment during the perinatal period is likely to have detrimental effects on maternal well-being, especially among low-income ethnic minority mothers who are at increased risk for experiencing postpartum depressive symptoms. With a sample of 322 Mexican and Mexican American families, this study used latent class growth analysis to identify meaningful subgroups of women based on their perceived family negativity reported prenatally and at 6, 12, 18, and 24 weeks postpartum. A 4-trajectory model of family negativity fit the data well: low-stable (58%), moderate-increasing (26%), high-decreasing (8%), and high-increasing (8%). Higher prenatal depressive symptomatology predicted membership in the moderate-increasing, high-decreasing, and high-increasing trajectories, relative to the low-stable trajectory. Findings suggest substantial heterogeneity in family negativity, identifying three significant growth patterns during the perinatal period with differential implications for maternal depressive symptomatology at 24 weeks and 12 months after delivery.

Brief Psychological Intervention Through Mobile App and Conference Calls for the Prevention of Depression in Non-Professional Caregivers: A Pilot Study

Despite its potential, no intervention aimed at non-professional caregivers administered through a smartphone app has been proven to prevent depression. The objective of this pilot study was to evaluate the efficacy and feasibility of an indicated depression-prevention intervention for non-professional caregivers administered through an app with the addition of conference-call contact. The intervention was administered to 31 caregivers (Mean age = 54.0 years, 93.5% women). An independent evaluation determined the incidence of depression, depressive symptoms, risk of developing depression, and the variables in the theoretical model (positive environmental reinforcement, negative automatic thoughts) at the pre-intervention and post-intervention, as well as the one- and three-month follow-ups. The incidence of depression at 3 months of follow-up was 6.5%. There was a significant reduction in depressive symptoms (p < 0.001) and in the risk of developing depression (p < 0.001) at the post-intervention and at the one- and three-month follow-ups. The model’s variables improved significantly after the intervention and were associated with post-intervention depressive symptoms. The intervention was more effective in caregivers who had a lower level of depressive symptoms at the pre-intervention. Adherence and satisfaction with the intervention were high. The results encourage future research using a randomized controlled clinical trial.

Problem-solving intervention to prevent depression in non-professional caregivers: a randomized controlled trial with 8 years of follow-up

BACKGROUND

Studies of psychological interventions for the prevention of depression have found significant effects in the short-term, but the long-term efficacy has yet to be determined. This study evaluated the 8-year effect of a randomized controlled trial for indicated prevention of depression in female caregivers.

METHODS

A total of 173 non-professional female caregivers with subclinical depressive symptoms not meeting criteria for a major depressive episode (MDE) were randomized to either a brief problem-solving intervention (n = 89) or usual-care control group (n = 84). Blinded evaluators conducted an assessment at the 8-year follow-up. The primary outcome was Depression Status, defined by diagnoses of MDE since the 1-year follow-up using the Structured Clinical Interview for the Disorders of the DSM-5. The secondary outcome was current Depressive Symptom Severity. Regression analyses were conducted to evaluate the effect of the intervention on the outcomes.

RESULTS

There were no significant differences in the Depression Status between the problem-solving (30.3%) and control groups (26.2%) (adjusted OR 1.25, 95% CI -0.58 to 2.69). Depressive Symptom Severity, however, was significantly lower in the problem-solving group compared to the control group at this follow-up, amounting to a small effect size of Cohen's d = 0.39 (adjusted B = -3.32, p = 0.018).

CONCLUSIONS

This is the first study to assess such a long-term follow-up of intervention of indicated prevention of depression. Results seem to indicate that the protective effect of the intervention became smaller over time during follow-up. Future research should replicate these results.

Explanatory Model for Asthma Disparities in Latino Children: Results from the Latino Childhood Asthma Project

BACKGROUND

Little research has been conducted that integrates, in one explanatory model, the multitude of factors potentially leading to disparities among Latino children.

PURPOSE

A longitudinal, observational study tested an explanatory model for disparities in asthma control between Mexican and Puerto Rican children with persistent asthma requiring daily controller medication use.

METHODS

Mexican and Puerto Rican children aged 5-12 years (n = 267) and their caregivers (n = 267) were enrolled and completed interviews and child spirometry at baseline and 3, 6, 9, and 12 months postenrollment. A 12 month retrospective children's medical record review was completed. Participants were recruited from two school-based health clinics and the Breathmobile in Phoenix, AZ, and two inner-city hospital asthma clinics in the Bronx, NY.

RESULTS

Statistically significant differences in the social/contextual predictors of asthma illness representations (IRs) were noted between Mexican and Puerto Rican caregivers. The structural equation model results revealed differences in asthma control over time by ethnicity. This model accounted for 40%-48% of the variance in asthma control test scores over 12 months. Caregivers' IRs aligned with the professional model of asthma management were associated with better children's asthma control across 1 year. These results also supported the theoretical notion that IRs change over time impacting caregivers' treatment decisions and children's asthma control.

CONCLUSIONS

These findings extend a previous cross-sectional model test using a more comprehensive model and longitudinal data and highlight the importance of considering within-group differences for diagnosis and treatment of children coming from the vastly heterogeneous Latino umbrella group.

Analysis of the Components of a Cognitive-Behavioral Intervention for the prevention of Depression Administered via Conference Call to Nonprofessional Caregivers: A Randomized Controlled Trial

Effective and accessible interventions for indicated prevention of depression are necessary and lacking, especially for informal caregivers. Although telephone-based interventions could increase the accessibility for caregivers, randomized controlled trials are scarce, with no examination of prevention to date. Moreover, the efficacy of specific therapeutic components in preventive cognitive-behavioral programs is unknown. The main objective of this study was to evaluate the efficacy of a telephone-administered psychological preventive intervention in informal caregivers with high depressive symptoms. A total of 219 caregivers were randomized to a cognitive-behavioral conference call intervention (CBCC, n = 69), a behavioral-activation conference call intervention (BACC, n = 70), or a usual care control group (CG, n = 80). Both interventions consisted of five 90-minute group sessions. At the post-intervention, incidence of depression was lower in CBCC and BACC compared to CG (1.5% and 1.4% vs. 8.8%). Relative risk was 0.17 for the CBCC and 0.16 for the BACC, and the number-needed-to-treat was 14 in both groups. Depressive symptoms were significantly lower in BACC and BACC groups compared to CG (d = 1.16 and 1.29), with no significant differences between CBCC and BACC groups. The conference call intervention was effective in preventing depression and the behavioral-activation component (BACC) was comparable to the CBCC intervention.

Pathways to Maternal and Child Well-Being: Stability and Transaction across Toddlerhood

OBJECTIVE

This study examines the development of minor parenting stress, parenting satisfaction, and dyadic dysregulation across early childhood and evaluates their roles in predicting maternal and child well-being one year later.

DESIGN

Data was collected from 322 low-income, Mexican American mother-child dyads at child ages 12, 18, 24, and 36 months. Mothers responded to questionnaires during structured interviews, and mother-child dyadic interactions were observed during structured teaching tasks and later coded for global displays of emotional, attentional, and behavioral dysregulation.

RESULTS

Cross-lag path analyses revealed negative concurrent relations between minor parenting stress and parenting satisfaction at every time point and stability in constructs across time. Parenting stress predicted greater subsequent dyadic dysregulation. Greater dyadic dysregulation and stress related to parenting predicted more maternal depressive symptoms and child behavior problems, whereas greater parenting satisfaction predicted less maternal depressive symptoms and child behavior problems.

CONCLUSION

In this minority at-risk population, there was substantial stability in and a lack of transactional relations between minor parenting stresses, parenting satisfaction, and dyadic dysregulation across toddlerhood. These factors are important determinants of maternal and child well-being, with minor parenting stress emerging as particularly powerful.

Cognitive-behavioral intervention via interactive multimedia online video game for active aging: study protocol for a randomized controlled trial

BACKGROUND

Due to the progressive aging of the population, programs to promote active aging have been recommended. However, older adults have difficulty accessing them. Interventions administered through online video games may increase their accessibility, and complementing these with a smartphone app will likely increase adherence and allow for ongoing professional monitoring. The objective of this study is to evaluate the efficacy of a cognitive-behavioral intervention for active aging administered through an online interactive multimedia video game that includes a smartphone app companion. The secondary objectives are to analyze the moderators and mediators of the change in the outcome variables and to evaluate the adherence to the intervention.

METHODS/DESIGN

A randomized controlled clinical trial will be conducted. Adults 45 years and older will be randomly assigned to a cognitive-behavioral intervention administered through an online multimedia video game that includes a smartphone app companion or to a control group that will receive online information on active aging (274 participants per group). The intervention will be administered in eight weekly 45-min modules. An investigator-blinded evaluation will be conducted using online self-administered tests at baseline, post-intervention, and 6- and 12-month follow-ups. The primary outcome will be mental health status as evaluated using the 36-item Short-Form Health Survey (SF-36) at post-intervention. Secondary outcomes will be emotional well-being, depressive symptoms, reinforcement, negative thoughts, self-reported memory, cognitive task performance, sleep hygiene behaviors, physical activity, eating habits, body mass index, social support, dropout, treatment adherence, and satisfaction with the intervention.

DISCUSSION

If the results are favorable, this study would involve the development of the first evidence-based active aging promotion intervention based on a video game that includes a smartphone app companion, providing evidence on its efficacy, accessibility, and clinical utility.

Depression and Quality of Life in Older Gay and Bisexual Men in Spain and Portugal

The purpose of this study was to assess levels of depressive symptoms and quality of life in older gay and bisexual older Spanish and Portuguese men and explore associations between these two samples and these variables. Using online surveys, 191 older gay and bisexual men from Spain and Portugal (mean age = 70 years) completed the Spanish and Portuguese versions of the Center for Epidemiologic Studies—Depression Scale and World Health Organization Instrument to Assess Quality of Life. Overall, moderate levels of depression and quality of life were found. Gay men and Spanish men report higher levels of depressive symptoms than bisexual and Portuguese men. Gay men score higher on physical health dimensions; bisexual men score higher on the social relationships dimension. Lower levels of physical health, psychological symptoms, and social relationships were significant predictors of depressive symptoms. These exploratory findings offer both similarities and differences between the samples from the two countries—and with U.S. data—and further evidence of the pervasive experience of depression in the lives of sexual minority older men with a renewed awareness of myriad contexts within which individuals age.

Telomere length and childhood trauma in Colombians with depressive symptoms

OBJECTIVE

Childhood trauma and telomere length (TL) are important risk factors for major depressive disorder. We examined whether there was an association between childhood trauma and TL in a sample of Colombians who were assessed for depressive symptoms.

METHODS

We applied the Center for Epidemiologic Studies Depression scale, the Patient Health Questionnaire-9, the Hospital Anxiety and Depression scale and the Childhood Trauma Questionnaire to 92 Colombian subjects (mean age = 21). TL was measured with quantitative PCR. Spearman's correlation coefficient (rs) was used to analyze the relationship between childhood trauma scores and TL.

RESULTS

We found a significant correlation between TL and sexual abuse scores (rs = 0.428, p = 0.002) in individuals with higher depressive symptom scores.

CONCLUSION

This is the first report of a significant association between TL and sexual abuse in a Latin American sample and provides additional evidence about the role of childhood trauma and TL in neuropsychiatric disorders.

Cognitive behavioral intervention via a smartphone app for non-professional caregivers with depressive symptoms: study protocol for a randomized controlled trial

Background

Although major depression is a frequent disorder in non-professional caregivers and there are effective psychological interventions to prevent it, caregivers have difficulty accessing them. Interventions for depression applied through an app could improve accessibility; yet, to date, adherence to such interventions has been low. The objectives of this study are to (1) evaluate the efficacy of a cognitive behavioral depression prevention intervention administered through a smartphone app with and without telephone conference calls, (2) analyze the mediators of the change in the incidence of depression and depressive symptoms, and (3) assess adherence and satisfaction with the interventions.

Methods

A randomized controlled clinical trial will be conducted. Caregivers with elevated symptoms will be randomly assigned to a cognitive behavioral intervention administered by a smartphone app (CBIA) group, a CBIA plus telephone conference calls (TCCs) group (CBIA + TCC), or an attention control group. Each condition will consist of approximately 58 participants. Both interventions will be administered in five modules through a smartphone app and the CBIA + TCC group will receive additional TCCs in group format (four sessions of 30 min each). Trained blind assessors will conduct pre-treatment, post-treatment and follow-up assessments at 1, 3, 6, and 12 months.

Discussion

This study will provide evidence of the efficacy of a cognitive behavioral intervention to prevent depression in caregivers with elevated depressive symptoms administered through a smartphone app and the impact of feedback applied through conference calls to increase program adherence and efficacy. If the results were favorable, it would mean that we have developed a more effective, accessible, and clinically useful preventive depression intervention than the currently available ones for many present and future caregivers.

Psychometric Properties of the Cognitive Emotion Regulation Questionnaire (CERQ) in Patients with Fibromyalgia Syndrome

Given that Fibromyalgia Syndrome (FMS) is associated with problems in emotion regulation, the importance of assessing this construct is widely acknowledged by clinical psychologists and pain specialists. Although the Cognitive Emotion Regulation Questionnaire (CERQ) is a self-report measure used worldwide, there are no data on its psychometric properties in patients with FMS. This study analyzed the dimensionality, reliability, and validity of the CERQ in a sample of 231 patients with FMS. Given that "fibrofog" is one of the most disabling FMS symptoms, in the present study, items in the CERQ were grouped by dimension. This change in item presentation was conceived as an efficient way of facilitating responses as a result of a clear understanding of what the items related to each dimension are attempting to measure. The following battery of measures was administered: the CERQ, the Revised Fibromyalgia Impact Questionnaire, the Pain Catastrophizing Scale, the Center for Epidemiologic Studies Depression Scale, and the State-Trait Anxiety Inventory. Four models of the CERQ structure were examined and confirmatory factor analyses supported the original factor model, consisting of nine factors-Self-blame, Acceptance, Rumination, Positive refocusing, Refocus on planning, Positive reappraisal, Putting into perspective, Catastrophizing, and Other-blame. There was minimal overlap between CERQ subscales and their internal consistency was adequate. Correlational and regression analyses supported the construct validity of the CERQ. Our findings indicate that the CERQ (items-grouped version) is a sound instrument for assessing cognitive emotion regulation in patients with FMS.

Analysis of the components of a cognitive-behavioral intervention administered via conference call for preventing depression among non-professional caregivers: a pilot study

OBJECTIVES

The primary aim was to assess the feasibility/acceptability of a preventive cognitive-behavioral intervention implemented via conference call for caregivers. The secondary aim was to conduct a preliminary assessment of the efficacy of the behavioral activation component alone compared to the complete cognitive-behavioral intervention.

METHOD

Sixty-one caregivers (mean age 58.4 years) were randomly assigned to a cognitive-behavioral intervention via conference call (CBC, n = 20), a behavioral activation intervention via conference call (BAC, n = 22) or a control group receiving usual care (CG, n = 19). Both interventions consisted of five 90-minute group sessions implemented weekly.

RESULTS

Only 6.6% of caregivers discontinued the study. In the CBC and BAC groups, attendance and satisfaction with the intervention were similarly high among both groups. Homework adherence was also high in both groups. At post-treatment, there was a lower incidence of depression in the CBC and BAC groups compared to the CG (0.0% for BAC and CBC vs. 10.5% for CG). The relative risk was 0.0, and number needed to treat was 10 in both groups. Depressive symptoms were significantly reduced in the CBC and BAC groups compared to the CG (d = 2.18 and d = 2.06).

CONCLUSION

The results support the feasibility of the intervention. Moreover, the BAC intervention was non-inferior to the CBC intervention for reducing depressive symptoms.

The efficacy of primary care chaplaincy compared with antidepressants: a retrospective study comparing chaplaincy with antidepressants

Aim To determine the effectiveness of primary care chaplaincy (PCC) when used as the sole intervention, with outcomes being compared directly with those of antidepressants. This was to be carried out in a homogenous study population reflective of certain demographics in the United Kingdom.

BACKGROUND

Increasing numbers of patients are living with long-term conditions and 'modern maladies' and are experiencing loss of well-being and depression. There is an increasing move to utilise non-pharmacological interventions such as 'talking therapies' within this context. Chaplaincy is one such 'talking therapy' but within primary care its evidence base is sparse with only one quantitative study to date. There is therefore a need to evaluate PCC excluding those co-prescribed antidepressants, as this is not evidenced in the literature as yet. PCC also needs to be directly compared with the use of antidepressants to justify its use as a valid alternative treatment for loss of well-being and depression.

METHODS

This was a retrospective observational study based on routinely collected data. There were 107 patients in the PCC group and 106 in the antidepressant group. Socio-demographic data were collected. Their pre- and post-intervention (either chaplaincy or antidepressant) well-being was assessed, by the Warwick-Edinburgh Mental Well-being Scale (WEMWBS) which is a validated Likert scale. Findings The majority of both groups were female with both groups showing marked ethnic homogeneity. PCC was associated with a significant and clinically meaningful improvement in well-being at a mean follow-up of 80 days. This treatment effect was maintained after those co-prescribed antidepressants were removed. PCC was associated with an improvement in well-being similar to that of antidepressants with no significant difference between the two groups.

Mediationg Role of Mindfulness as a Trait Between Attachment Styles and Depressive Symptoms

Attachment styles and dysfunctional symptoms have been associated. This relationship could be affected by metacognitive capacity. The aim of this study is to clarify the relationship between depressive symptoms, attachment styles, and metacognitive capacity. In addition, the mediating role of metacognition between attachment and depressive symptoms has been studied. A total of 505 participants recruited from the general population of the province of Bizkaia (Spain) completed questionnaires regarding depression, anxiety, mindfulness, decentering, and attachment. Results showed positive and significant relations between (a) dysfunctional symptoms and insecure attachment styles and (b) metacognitive capacity and secure attachment style. Additionally, the mediating role of metacognition between attachment and depressive symptoms was confirmed. Intervention in metacognitive abilities such as mindfulness could be a useful therapeutic tool for depressive symptoms.

Long-term Follow-up of a Randomized Clinical Trial Assessing the Efficacy of a Brief Cognitive-Behavioral Depression Prevention Intervention for Caregivers with Elevated Depressive Symptoms

OBJECTIVES

To evaluate the efficacy of a cognitive-behavioral intervention for the prevention of depression in caregivers with elevated depressive symptoms through 12 months of follow-up.

DESIGN

Randomized controlled trial.

SETTING

Community in Galicia (Spain).

PARTICIPANTS

170 caregivers with elevated depressive symptoms.

INTERVENTIONS

Caregivers were randomized to a cognitive-behavioral intervention (N = 88), administered to groups of five participants in five weekly 90-min sessions, or to a usual care control group (N = 82).

MEASUREMENTS

Major depressive episodes (according to the Structured Clinical Interview for Axis I Disorders of the DSM-IV), depressive symptoms, emotional distress, caregiver burden, pleasant activities, depressive thoughts, social contacts. Trained blinded interviewers conducted assessments at 1, 3, 6, and 12 months of follow-up.

RESULTS

At the 12-month follow-up, there was a lower incidence of major depressive episodes in the intervention group compared with the control group (3.4% versus 22.0%). The relative risk was 0.15 (95% CI: 0.05-0.51) and the number needed to treat was 5 (95% CI: 3-11). The time of delay of the depressive episode onset in the intervention group was significant. Caregivers with good compliance to the intervention had a lower incidence of depression. The effects of the intervention on depressive symptoms, emotional distress, and caregiver burden were maintained for 12 months. Younger caregivers were more likely to benefit from the intervention. The change in depressive thoughts mediated the reduction in depressive symptoms.

CONCLUSIONS

Depressive episodes can be successfully prevented in caregivers, with long-term effects.

Differential response to depression prevention among a sample of informal caregivers: Moderator analysis of longer-term follow-up trial data

Depression is one of the most common mental disorders in caregivers. Therefore, preventive interventions for this population are needed, especially for caregivers with subclinical symptoms of depression. However, no study to date has identified the characteristics of caregivers that help to predict who will or will not benefit from such a preventive intervention. This study aimed to identify moderators of response to intervention comparing problem solving and usual care in indicated prevention of depression among informal caregivers. A randomized controlled trial was conducted involving 173 participants who were allocated to the problem-solving intervention (n=89) or the usual-care control-group (n=84), with 12-months follow-up. Socio-demographic, care-related and clinical variables at baseline were analyzed as potential moderators of intervention response at 12-months follow-up. Age and emotional distress emerged as significant moderators. Those caregivers younger than 65 years and with higher emotional distress at baseline were more likely to benefit from the intervention than from usual care. Simultaneous consideration of multiple moderators found that intervention was indicated for 95.4% of the sample. Considering these moderators in clinical decision-making could contribute to matching treatments and health service users in a more personalized and effective way.

Protocol for a randomized controlled dismantling study of a brief telephonic psychological intervention applied to non-professional caregivers with symptoms of depression

BACKGROUND

Although depression is a common problem in caregivers and there are effective cognitive-behavioral interventions for its prevention, the ability of caregivers to attend these treatments is often limited by logistics. Furthermore, the efficacy of the components of these interventions is unknown. The objectives of this study are to (a) evaluate the efficacy of a telephone-administered cognitive-behavioral intervention to prevent depression with all its components (cognitive and behavioral) and only with behavioral activation, and to (b) analyze the mediators of the change in depressive symptoms.

METHODS/DESIGN

A randomized controlled clinical trial was designed to dismantle the components of a cognitive-behavioral intervention. Caregivers with elevated depressive symptoms will be randomly assigned to a cognitive-behavioral intervention, an intervention with only the behavioral activation component, or a usual care control group. Each condition will consist of approximately 60 participants. The two interventions will consist of five sessions lasting 90 min each, applied to groups of about 5 participants at a time via conference call. Trained interviewers, blind to the experimental conditions, will conduct the assessments at the pre-treatment, post-treatment and 1-, 3-, 6- and 12-month follow-ups.

DISCUSSION

This study will provide evidence of the efficacy of a cognitive-behavioral intervention to prevent depression in caregivers with elevated depressive symptoms administered via conference call, and on the impact of the behavioral activation component on the overall efficacy of the program. If we find favorable results, it would mean that we have developed a program of prevention of depression of higher clinical utility and efficacy than those currently available, which would make it possible for a large number of caregivers to have access to such resources.

Long-term efficacy of indicated prevention of depression in non-professional caregivers: randomized controlled trial

BACKGROUND

Although depression is a common problem among non-professional caregivers, only one trial has evaluated the efficacy of indicated prevention targeting this population and the long-term efficacy is unknown. The aim of this study was to evaluate the long-term efficacy of a brief intervention for the indicated prevention of depression in a sample of female caregivers.

METHOD

A randomized controlled trial was conducted involving 173 participants (mean age 53.9 years) who were allocated to the intervention (n = 89) or the usual-care control group (n = 84). Blinded interviewers conducted assessments at 1, 3, 6 and 12 months of follow-up. The main outcome measure was the incidence of major depression and the secondary outcomes were compliance with treatment, depressive symptoms, emotional distress and caregiver burden.

RESULTS

At the 12-month follow-up, a lower incidence of depression as evaluated using the Structured Clinical Interview for Axis I Disorders of the DSM-IV was found in the intervention group compared with the control group (10.1% v. 25.0%). The relative risk was 0.40 and statistically significant [χ2 = 6.68, degrees of freedom = 1, p = 0.010, 95% confidence interval (CI) 0.20-0.81], and the number needed to treat was 7 (95% CI 4-27). There was a significant delay in the onset of depression in the intervention group (p = 0.008). The good complier caregivers had a lower incidence of depression. The intervention effect on depressive symptoms, emotional distress and caregiver burden were maintained for 12 months.

CONCLUSIONS

This is the first study to demonstrate that a brief problem-solving intervention can prevent the onset of depression among non-professional caregivers over the longer term.

RELATIONSHIP OF COGNITIVE BEHAVIORAL THERAPY EFFECTS AND HOMEWORK IN AN INDICATED PREVENTION OF DEPRESSION INTERVENTION FOR NON-PROFESSIONAL CAREGIVERS (.)

Activities designed to be performed outside of the intervention are considered an essential aspect of the effectiveness of cognitive-behavioral therapy. However, these have received little attention in interventions aimed at individuals with subclinical depressive symptoms who do not yet meet diagnostic criteria for depression (indicated prevention). In this study, the completion of tasks given as homework and their relationship with post-treatment depressive symptoms was with relation to an indicated prevention of depression intervention. Eighty-nine female non-professional caregivers recruited from an official registry completed an intervention involving 11 homework tasks. Tasks performed were recorded and depressive symptoms were assessed with the Center for Epidemiologic Studies Depression Scale (CES-D). Among caregivers, 80.9% completed 9-11 tasks. The number of tasks performed was associated with post-treatment depressive symptoms, with 9 being optimal for clinically significant improvement. These findings highlight the relationship between homework and post-treatment depressive symptoms.

"Greenlight study": a controlled trial of low-literacy, early childhood obesity prevention

Children who become overweight by age 2 years have significantly greater risks of long-term health problems, and children in low-income communities, where rates of low adult literacy are highest, are at increased risk of developing obesity. The objective of the Greenlight Intervention Study is to assess the effectiveness of a low-literacy, primary-care intervention on the reduction of early childhood obesity. At 4 primary-care pediatric residency training sites across the US, 865 infant-parent dyads were enrolled at the 2-month well-child checkup and are being followed through the 24-month well-child checkup. Two sites were randomly assigned to the intervention, and the other sites were assigned to an attention-control arm, implementing the American Academy of Pediatrics' The Injury Prevention Program. The intervention consists of an interactive educational toolkit, including low-literacy materials designed for use during well-child visits, and a clinician-centered curriculum for providing low-literacy guidance on obesity prevention. The study is powered to detect a 10% difference in the number of children overweight (BMI > 85%) at 24 months. Other outcome measures include observed physician-parent communication, as well as parent-reported information on child dietary intake, physical activity, and injury-prevention behaviors. The study is designed to inform evidence-based standards for early childhood obesity prevention, and more generally to inform optimal approaches for low-literacy messages and health literacy training in primary preventive care. This article describes the conceptual model, study design, intervention content, and baseline characteristics of the study population.

Predictors of trait dissociation and peritraumatic dissociation induced via cold pressor

Understanding which factors predict individual dissociative response during stressful situations is important to clarify the nature of dissociation and the mechanisms associated to its use as a coping strategy. The present study examined (1) whether experiential avoidance (EA), anxiety sensitivity (AS), depressive symptoms, and state anxiety concurrently predicted trait dissociation (TD)-absorption, amnesia, depersonalization, and total TD scores-and laboratory induced dissociation (LID); and (2) whether TD and catastrophizing predicted LID. We also examined whether catastrophizing mediated the relationships between both AS and depressive symptoms and LID. A total of 101 female undergraduate students participated in a cold pressor task, which significantly induced dissociation. Results of hierarchical regression analyses showed that AS at Time 1 (9 months before the experimental session), as well as depressive symptoms and catastrophizing at the time of the experiment (Time 2), predicted LID at Time 2. Depressive symptoms at Time 2 predicted total TD, absorption, and amnesia scores. AS at Time 1 and depressive symptoms at Time 2 predicted depersonalization. AS, depressive symptoms, and catastrophizing seem to facilitate the use of dissociative strategies by healthy individuals, even in response to non-traumatic but discomforting stress.

Association of trauma, posttraumatic stress disorder, and experimental pain response in healthy young women

BACKGROUND

Evidence of pain alterations in trauma-exposed individuals has been found. The presence of posttraumatic stress disorder (PTSD) may be explaining these alterations, as some of the psychological characteristics of PTSD are hypothesized to increase pain response.

OBJECTIVES

To examine differences in pain response and in certain psychological variables between trauma-exposed women (TEW) with PTSD, TEW without PTSD, and non-trauma-exposed women (NTEW) and to explore the role of these psychological variables in the differences in pain response between the groups.

METHODS

A total of 122 female students completed a cold pressor task (42 TEW with PTSD, 40 TEW without PTSD, and 40 NTEW). Anxiety sensitivity, experiential avoidance, trait and state dissociation, depressive symptoms, state anxiety, catastrophizing, and arousal were assessed.

RESULTS

TEW with PTSD reported significantly higher pain unpleasantness than NTEW, but not more than that of TEW without PTSD. They also presented higher trait dissociation, state anxiety, depressive symptoms, and skin conductance than the other 2 groups and higher anxiety sensitivity than TEW without PTSD. TEW without PTSD reported more pain unpleasantness than NTEW, but they recovered faster from pain. However, these differences were not explained by any psychological variable.

CONCLUSIONS

The results suggest that although trauma-exposed individuals are not more sensitive to painful stimulation, they evaluate pain in a more negative way. Exposure to trauma itself, but not to PTSD, may explain the differences found in pain unpleasantness.

Factorial structure of the Spanish center for epidemiologic studies depression scales in HIV patients

The factor structure of the Center for Epidemiological Studies Depression Scale (CES-D) (Radloff in Appl Psychol Meas 1(3):385-401, 1977) was examined in two independent samples of human immunodeficiency virus (HIV) patients. The first sample, composed of HIV patients undergoing hospital follow-up, was used to explore the factor structure of the CES-D. The second sample, composed of HIV patients confined in prison, was used to confirm the factor structure previously found. In both samples the best structure accounting for data was three 1st-order factors with a general 2nd-order factor of depression. We found a strong factorial invariance of this structure across samples, pointing out a high consistency of results in HIV patients. Additionally, the cut-off score for depression screening in this population was studied.

Trauma exposure and health: the role of depressive and hyperarousal symptoms

Posttraumatic stress disorder (PTSD) and depressive symptoms have been theorized to mediate the relationship between trauma exposure and physical health symptoms. Although empirical evidence supports this premise, studies conducted to date have employed statistical mediation analyses that are now broadly criticized. Furthermore, the mediating roles of both PTSD and depressive symptoms have seldom been examined concurrently, and it remains unclear which PTSD symptom clusters uniquely mediate this relationship. The aim of the present study was to examine the mediating role of reexperiencing, avoidance/numbing, hyperarousal, and depressive symptoms in the relationship between trauma exposure and physical health symptoms. Participants were 516 Spanish female undergraduate students. Physical health symptoms were compared between those who reported trauma exposure (n = 266) and those who did not (n = 250). Data from trauma-exposed participants were analyzed using regression models with bootstrapping to test mediation. Results of the analyses showed that the trauma-exposed group reported significantly more physical health symptoms (r(2) = .035). Hyperarousal and depressive symptoms uniquely mediated the relationship between trauma exposure and physical health symptoms. Our findings clarify some of the mechanisms by which negative health consequences occur subsequent to trauma exposure.

Validation of the Spanish Center for Epidemiological Studies Depression and Zung Self-Rating Depression Scales: a comparative validation study

BACKGROUND

Depressive disorders are leading contributors to burden of disease in developing countries. Research aiming to improve their diagnosis and treatment is fundamental in these settings, and psychometric tools are widely used instruments to support mental health research. Our aim is to validate and compare the psychometric properties of the Spanish versions of the Center for Epidemiological Studies Depression Scale (CES-D) and the Zung Self-Rating Depression Scale (ZSDS).

METHODOLOGY/PRINCIPAL FINDINGS

A Spanish version of the CES-D was revised by 5 native Spanish speaking psychiatrists using as reference the English version. A locally standardized Spanish version of the ZSDS was used. These Spanish versions were administered to 70 patients with a clinical diagnosis of DSM-IV Major Depressive Episode (MDE), 63 without major depression but with clinical diagnosis of other psychiatric disorders (OPD), and 61 with no evidence of psychiatric disorders (NEP). For both scales, Cronbach's alpha (C-α) and Hierarchical McDonald Omega for polychoric variables (MD-Ω) were estimated; and receiver operating characteristics (ROC) analysis performed. For the CES-D and ZSDS scales, C-α was 0.93 and 0.89 respectively, while MD-Ω was 0.90 and 0.75 respectively. The area under the ROC curve in MDE+OPD was 0.83 for CES-D and 0.84 for ZSDS; and in MDE+NEP was 0.98 for CES-D and 0.96 for ZSDS. Cut-off scores (co) for the highest proportions of correctly classified (cc) individuals among MDE+OPD were ≥29 for CES-D (sensitivity (ss) = 77.1/specificity (sp) = 79.4%/(cc) = 78.2%) and ≥47 for ZSDS (ss = 85.7%/sp = 71.4%/cc = 78.9%). In the MDE+NEP, co were ≥24 for the CES-D (ss = 91.4%/sp = 96.7%/cc = 93.9%) and ≥45 for the ZSDS (ss = 91.4%/sp = 91.8%/cc = 91.6%).

CONCLUSION

Spanish versions of the CES-D and ZSDS are valid instruments to detect depression in clinical settings and could be useful for both epidemiological research and primary clinical settings in settings similar as those of public hospitals in Lima, Peru.

Prevalence of depressive and other central nervous system symptoms in HIV-infected patients treated with HAART in Spain

This study was conducted to assess the prevalence of depressive symptoms, sleep disturbances, and subjective cognitive complaints in patients with HIV receiving highly active antiretroviral therapy. Participants completed the "Center for Epidemiological Studies Depression Scale" (CES-D) and a questionnaire on sleep disturbances and subjective cognitive complaints. Mean age of the 799 participants was 43.7 years and 67% were men. Adjusted prevalence of CES-D was 35.4% (95% confidence interval [CI]: 32.0-38.7), with no significant differences between gender and age groups. Sleep disturbances were more prevalent in older versus younger participants (74.0% [95% CI: 70.4-77.7] versus 63.3% [95% CI: 56.8-69.8]). Cognitive complaints were more prevalent in women (52.3% [95% CI: 46.4-58.2]) when compared with men (48.2% [95% CI: 44.7-51.6]). Hepatitis C virus coinfection was a strong predictor of depressive symptoms. Male gender and detectable viral load were independent risk factors for sleep disturbance. A higher CES-D score was an independent risk factor for sleep disturbance and cognitive complaints.

Impact of anxiety and depression on chronic obstructive pulmonary disease exacerbation risk

Chronic obstructive pulmonary disease (COPD) exacerbations contribute significantly to morbidity and mortality. COPD is also associated with high levels of psychological distress, which has been linked with higher exacerbation rates. At a recent American Thoracic Society conference symposium titled "Depression and Obstructive Lung Disease: State of the Science and Future Directions" held in 2010 in New Orleans, clinicians and researchers identified a number of important research priorities related to psychiatric comorbidities, including the need to better understand their impact on COPD outcomes, such as exacerbations. This article reviews the current literature and quantifies the prospective impact of anxiety and depression on exacerbation risk in patients with COPD. The limitations of the existing literature and the perspectives for future research are addressed.

Psychometric value of the Center for Epidemiologic Studies Depression (CES-D) scale for screening of depressive symptoms in Armenian population

BACKGROUND

This study examined the psychometric value of the Center for Epidemiologic Studies Depression Scale (CES-D) translated for use with an Armenian population.

METHODS

Using data obtained from a country-wide health survey of 2310 households involving female and male respondents aged 18 and over, we investigated the response pattern to the CES-D items, the factor structure, internal consistency, inter-item correlations of the total scale and its negatively and positively formulated subscales. We used logistic regression analysis to relate the constructs measured by the CES-D and its subscales to known determinants of depression.

RESULTS

Armenian respondents of both genders significantly suppressed their positive emotions, thus over-endorsing positively formulated (reverse-coded) items, therefore producing artificially high depression scores. Factor analysis of the scale yielded a three-factor structure (combined Depressed/Somatic, Positive Affect, and Interpersonal). The Positive Affect factor correlated weakly with the other two factors, and its inclusion reduced the internal consistency of the whole scale. Unlike the 16-item subscale of negatively formulated items, Positive Affect was not related to several known determinants of depression and did not reflect known depression-specific differences between genders. The set of determinants of Positive Affect included mainly lifestyle and attitudinal variables.

LIMITATIONS

This study did not assess the concurrent and discriminate validity of the Armenian CES-D.

CONCLUSIONS

For Armenians, the construct measured by the four Positive Affect items of CES-D is not related to depressive symptoms as measured by the other items. It introduces ethnical/cultural response bias in CES-D score and reduces the cross-cultural comparability of the latter.

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

BACKGROUND

Previous 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.

METHODS

A 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.

RESULTS

The 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.

CONCLUSION

This 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.

The Center for Epidemiologic Studies Depression Scale: factor validity and reliability in a French sample of adolescents with Intellectual Disability

The purpose of this study was to test the factor validity and reliability of the Center for Epidemiologic Studies Depression Scale (CES-D) within a sample of adolescents with mild to moderate Intellectual Disability (ID). A total sample of 189 adolescents (121 boys and 68 girls), aged between 12 and 18 years old, with mild to moderate ID were involved in two studies. In study 1, the content, phrasing and answering format of the CES-D were adapted for adolescents with ID. This instrument was renamed CES-D for ID (CES-D-ID) and two different versions based on two alternative answer scales (Likert and Likert-graphical) were developed and their psychometric properties were verified in study 2. The results provided support for the factor validity, reliability and invariance across gender and age of a 14-item version of the CES-D-ID based on a Likert-graphical answer scale.

Emotional Intelligence in Women Caregivers with Depressive Symptoms

The emotional intelligence of a sample of 59 women caregivers ( M age = 51.1 yr.) with depressive symptoms was compared with that of a sample of adult women from the general population ( M age = 50.7 yr.). No group differences were observed on the Trait Meta-Mood Scale's three dimensions of emotional intelligence across age, socioeconomic status, or education level. Compared with the general population sample, the caregivers group scored significantly lower on Attention to Feelings and Mood Repair.

A very short visual analog form of the Center for Epidemiologic Studies Depression Scale (CES-D) for the idiographic measurement of depression

BACKGROUND

The experience sampling method, also referred to as ecological momentary assessment (ESM-EMA) has recently gained popularity in the study of depression. However, no psychometrically sound multidimensional depression questionnaires specifically designed for the ESM-EMA context are currently available.

AIMS

The main objective of the present study was to develop and validate a very short visual analog scale of the Center for Epidemiologic Studies Depression Scales (CES-D-VAS-VS) specifically designed for the ESM-EMA context. To this end, the full French version of the CES-D was adapted for the ESM-EMA context. From this full-length adapted version a very short version was then extracted from this longer instrument and validated.

STUDY DESIGN

A sample comprising 163 patients with a major depressive episode (MDE) and 306 participants without mental disorders was involved in this study.

RESULTS

The obtained results provided support for the factor validity, strong measurement invariance (invariance of the loadings and intercepts of the measurement model) across sex and clinical status groups, reliability and convergent validity of the CES-D-VAS-VS. This instrument comprises 4 items measuring positive affect, depressive affect, somatic complaints and disturbed interpersonal relationships.

CONCLUSION

The present results provide preliminary evidence regarding the construct validity of the CES-D-VAS-VS among patients and community adults sample but also underline the need to rely on latent variables methods in the use of this instrument to account for the differential levels of measurement errors (uniquenessess) that were observed across groups.

The impact of psychological distress on exacerbation rates in COPD

BACKGROUND

exacerbations are common in chronic obstructive pulmonary disease (COPD) and contribute significantly to COPD morbidity and mortality. COPD is also associated with high levels of psychological distress, which has been shown to be associated with higher exacerbation rates. However, the existing literature on the association between psychological distress and exacerbation risk remains largely misunderstood.

OBJECTIVES

to critically review the current literature on the association between psychological distress (defined as anxiety and depressive symptoms or anxiety and depressive disorders) and COPD exacerbations in COPD patients, to highlight the limitations of the existing literature, and to provide recommendations for future research.

METHODS

a critical review of English-language peer-reviewed longitudinal and retrospective studies was conducted. The Ovid portal to Medline, EMBASE, and PsycINFO databases were accessed.

RESULTS

some acceptable evidence suggested that psychological distress confers greater risk for exacerbations, more specifically symptom-based exacerbations or those treated in the patient's own environment. However, most studies showed an absence of a positive association, especially with exacerbations leading to hospitalization.

CONCLUSIONS

methodological weaknesses and the use of a wide range of psychological tools mean that there is an inconsistent association between psychological distress and exacerbations in the current literature. However, psychological distress may confer greater risk for symptom-based rather than event-based defined exacerbations. Further studies are needed to more comprehensively assess the question, particularly in light of the high levels of both anxiety and depression in COPD patients.

Optimising the diagnostic performance of the Geriatric Depression Scale

The aim of this work is to empirically generate a shortened version of the Geriatric Depression Scale (GDS), with the intention of maximising the diagnostic performance in the detection of depression compared with previously GDS validated versions, while optimizing the size of the instrument. A total of 233 individuals (128 from a Day Hospital, 105 randomly selected from the community) aged 60 or over completed the GDS and other measures. The 30 GDS items were entered in the Day Hospital sample as independent variables in a stepwise logistic regression analysis predicting diagnosis of Major Depression. A final solution of 10 items was retained, which correctly classified 97.4% of cases. The diagnostic performance of these 10 GDS items was analysed in the random sample with a receiver operating characteristic (ROC) curve. Sensitivity (100%), specificity (97.2%), positive (81.8%) and negative (100%) predictive power, and the area under the curve (0.994) were comparable with values for GDS-30 and higher compared with GDS-15, GDS-10 and GDS-5. In addition, the new scale proposed had excellent fit when testing its unidimensionality with CFA for categorical outcomes (e.g., CFI=0.99). The 10-item version of the GDS proposed here, the GDS-R, seems to retain the diagnostic performance for detecting depression in older adults of the GDS-30 items, while increasing the sensitivity and predictive values relative to other shortened versions.
