International comparison of death place for suicide; a population-level eight country death certificate study.

PURPOSE: The places of death for people who died of suicide were compared across eight countries and socio-demographic factors associated with home suicide deaths identified. METHODS: Death certificate data were analyzed; using multivariable binary logistic regression to determine associations. RESULTS: National suicide death rates ranged from 1.4 % (Mexico) to 6.4 % (South Korea). The proportion of suicide deaths occurring at home was high, ranging from 29.9 % (South Korea) to 65.8 % (Belgium). Being older, female, widowed/separated, highly educated and living in an urban area were risk factors for home suicide. CONCLUSIONS: Home suicide deaths need specific attention in prevention programs.

Increasing Positive Outlook Partially Mediates the Effect of Empirically Supported Treatments on Depression Symptoms Among Adolescents.

Among adolescents there is evidence that cognitive change partially mediates the effect of cognitive behavioral therapy (CBT) on depression outcome. However, prior studies have been limited by small samples, narrow measures of cognition, and failure to compare cognitive change following CBT to cognitive change following antidepressant medication. This study examined whether change in four cognitive constructs (cognitive distortions, cognitive avoidance, positive outlook, and solution-focused thinking) mediated change in depression severity in a sample of 291 adolescents who participated in the Treatment for Adolescents with Depression Study (TADS). TADS assessed the effects of CBT, fluoxetine, and their combination on depression severity. All three treatments were associated with change in the cognitive constructs and combination treatment produced the greatest change. Furthermore, change in the cognitive constructs partially mediated change in depression severity within all three treatments. Results implicated positive outlook as the construct most associated with change in depression severity over 36 weeks.

Treating depression and oppositional behavior in adolescents.

Adolescents with depression and high levels of oppositionality often are particularly difficult to treat. Few studies, however, have examined treatment outcomes among youth with both externalizing and internalizing problems. This study examines the effect of fluoxetine, cognitive behavior therapy (CBT), the combination of fluoxetine and CBT, and placebo on co-occurring oppositionality within a sample of depressed adolescents. All treatments resulted in decreased oppositionality at 12 weeks. Adolescents receiving fluoxetine, either alone or in combination with CBT, experienced greater reductions in oppositionality than adolescents not receiving antidepressant medication. These results suggest that treatments designed to alleviate depression can reduce oppositionality among youth with a primary diagnosis of depression.

Ethnic differences among adolescents beginning treatment for depression.

This study examines ethnic/racial differences at the start of treatment among participants in the Treatment for Adolescents with Depression Study (TADS). African American and Latino youth were compared to Caucasian youth on symptom presentation and cognitive variables associated with depression. Contrary to hypothesis, there were no significant differences in symptom presentation as measured by the interview-based items of the Children's Depression Rating Scale--Revised (CDRS-R). However, African American and Latino youth were both rated as demonstrating more severe symptoms on the observational items of the CDRS-R compared to Caucasian youth. In terms of cognitive variables associated with depression, African Americans reported fewer negative cognitive biases compared to Caucasians, but cognitive biases were significantly correlated with depression severity across ethnic groups.

Findings from the Treatment for Adolescents with Depression Study (TADS): what have we learned? What do we need to know?

This introduction to the special section on findings from the Treatment for Adolescents with Depression Study provides a review of the rationale for the study, its design, and principal findings to date. Findings with regard to acute effectiveness of alternative treatments, relapse, recurrence, maintenance of gains, and the effects of treatment on suicidal ideations and suicidal behavior are reviewed. We conclude with a brief discussion of unresolved clinical issues, including treatment resistance, management of partial response, moderators and predictors of long-term response, and mediators of clinical change. The articles of the special section address a range of issues including relations between cognitive factors associated with depression, relations between maladaptive beliefs and treatment response, cognitive mediators of therapeutic improvement, relations between family conflict and treatment response, and the economic costs of adolescent depression.

Factor structure and psychometric properties of the Children's Negative Cognitive Error Questionnaire with a clinically depressed adolescent sample.

The factor structure and psychometric properties of the Children's Negative Cognitive Error Questionnaire (CNCEQ) were examined with 427 adolescents ages 12 to 18 (193 boys) with current major depressive disorder. Results of confirmatory factor analysis supported a four-factor model comprised of three content area factors (i.e., social, academic, athletic) and a general factor. Internal consistencies ranged between .84 and .94 for the total and three content area scores. Girls scored significantly higher than boys on all factors, but no age differences on the factors were found. Convergent and discriminant validity of the CNCEQ were supported. Results did not support the original subscales organized by type of cognitive distortion (e.g., catastrophizing, overgeneralizing). Findings indicated that the CNCEQ would be a useful clinical tool for assessing cognitive symptoms within relevant domains of functioning (e.g., social, academic) of depressed youth.

Cognitive measures of adolescent depression: unique or unitary constructs?

The factor structure of several self-report questionnaires assessing depression-relevant cognitions frequently employed in clinical research was examined in a sample of 390 adolescents (M age = 14.54; 216 girls; 74% Caucasian) with current major depressive disorder enrolled in the Treatment of Adolescents with Depression Study. A four-factor solution resulted, accounting for 65% of the total variance. The factors were labeled (a) Cognitive Distortions and Maladaptive Beliefs, (b) Cognitive Avoidance, (c) Positive Outlook, and (d) Solution-Focused Thinking. Internal consistencies for the factor-based composite scores were .83, .85, .84, and .82, respectively. Girls endorsed more negative cognitions than boys on three of the four factors. Maladaptive cognitions were positively related to severity of depression and predicted treatment response. Taken together, findings indicated that there are four distinct domains of cognitions that are present among adolescents with depression that are tapped by several widely used self-report measures of cognitions.

Dysfunctional attitudes scale perfectionism: a predictor and partial mediator of acute treatment outcome among clinically depressed adolescents.

The effect of perfectionism on acute treatment outcomes was explored in a randomized controlled trial of 439 clinically depressed adolescents (12-17 years of age) enrolled in the Treatment for Adolescents with Depression Study (TADS) who received cognitive behavior therapy (CBT), fluoxetine, a combination of CBT and FLX, or pill placebo. Measures included the Children's Depression Rating Scale-Revised, the Suicidal Ideation Questionnaire-Grades 7-9, and the perfectionism subscale from the Dysfunctional Attitudes Scale (DAS). Predictor results indicate that adolescents with higher versus lower DAS perfectionism scores at baseline, regardless of treatment, continued to demonstrate elevated depression scores across the acute treatment period. In the case of suicidality, DAS perfectionism impeded improvement. Treatment outcomes were partially mediated by the change in DAS perfectionism across the 12-week period.

Service use and costs of care for depressed adolescents: who uses and who pays?

Major depressive disorder is common in adolescence and is associated with significant morbidity and family burden. Little is known about service use by depressed adolescents. The purpose of this article is to report the patterns of services use and costs for participants in the Treatment for Adolescents with Depression Study sample during the 3 months before randomization. Costs were assigned across three categories of payors: families, private insurance, and the public sector. We examined whether costs from payors varied by baseline covariates, such as age, gender, insurance status, and family income. The majority (71%) of depressed youth sought services during the 3-month period. Slightly more than one-fifth had contact with a behavioral health specialist. The average participant had just under $300 (SD = $437.67, range = $0-$3,747.71) in treatment-related costs, with most of these costs borne by families and private insurers.

The dysfunctional attitudes scale: psychometric properties in depressed adolescents.

The psychometric properties and factor structure of the Dysfunctional Attitudes Scale were examined in a sample of 422 male and female adolescents (ages 12-17) with current major depressive disorder. The scale demonstrated high internal consistency (alpha = .93) and correlated significantly with self-report and interview-based measures of depression. Confirmatory factor analysis indicated that a correlated 2-factor model, with scales corresponding to perfectionism and need for social approval, provided a satisfactory fit to the data. The goodness-of-fit was equivalent across sexes and age groups. The findings support the use of the Dysfunctional Attitudes Scale and its subscales in the assessment of clinically depressed adolescents.

An exploratory analysis of the impact of family functioning on treatment for depression in adolescents.

This article explores aspects of family environment and parent-child conflict that may predict or moderate response to acute treatments among depressed adolescents (N = 439) randomly assigned to fluoxetine, cognitive behavioral therapy, their combination, or placebo. Outcomes were Week 12 scores on measures of depression and global impairment. Of 20 candidate variables, one predictor emerged: Across treatments, adolescents with mothers who reported less parent-child conflict were more likely to benefit than their counterparts. When family functioning moderated outcome, adolescents who endorsed more negative environments were more likely to benefit from fluoxetine. Similarly, when moderating effects were seen on cognitive behavioral therapy conditions, they were in the direction of being less effective among teens reporting poorer family environments.

Predictors of hopelessness among clinically depressed youth.

BACKGROUND: Factors that distinguish depressed individuals who become hopeless from those who do not are poorly understood. METHOD: In this study, predictors of hopelessness were examined in a sample of 439 clinically depressed adolescents participating in the Treatment for Adolescents with Depression Study (TADS). The total score of the Beck Hopelessness Scale (BHS) was used to assess hopelessness at baseline. Multiple regression and logistic regression analyses were conducted to evaluate the extent to which variables were associated with hopelessness and determine which cluster of measures best predicted clinically significantly hopelessness. RESULTS: Hopelessness was associated with greater depression severity, poor social problem-solving, cognitive distortions, and family conflict. View of self, view of the world, internal attributional style, need for social approval, positive problem-solving orientation, and family problems consistently emerged as the best predictors of hopelessness in depressed youth. CONCLUSIONS: Cognitive and familial factors predict those depressed youth who have high levels of hopelessness.

The long-term effect of trauma history on adolescent depression treatment.

BACKGROUND: Childhood trauma is associated with the development of depression during adolescence. Prior research suggests that traumatic experiences may result in differential acute treatment outcomes for depressed adolescents. However, the long-term effects of trauma on treatment response remain unclear. METHOD: Participants (N = 318) with a primary diagnosis of major depressive disorder were randomly assigned to 1 of 3 treatment groups: cognitive-behavioral therapy (CBT), fluoxetine (FLX), or their combination (COMB). All participants received 36 weeks of active treatment followed by 1 year of open follow-up. We hypothesized that (a) adolescents without a trauma history would have greater symptom reduction over the course of treatment compared to those with a trauma history and (b) there would be an interaction between trauma history, treatment arm, and time such that adolescents without trauma histories in combination treatment would improve the most rapidly. Linear mixed effects modeling, factorial ANOVAs, and log-linear analyses were used to test these hypotheses. RESULTS: The linear mixed effect model revealed a significant 3-way interaction of time, trauma, and treatment type. In the CBT and COMB groups, adolescents without trauma histories improved more rapidly than traumatized adolescents. In the single-time-point analyses, there were no significant differences between adolescents with trauma histories and those without trauma histories. CONCLUSIONS: Whereas all treatment groups experienced significant reductions in depression regardless of trauma history, adolescents without trauma histories receiving psychotherapy demonstrated more rapid improvements in depression symptom severity. Treatment response did not differ between traumatized and nontraumatized youth at long-term follow-up. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Marital and Parent-Child Relationships during Treatment for Adolescent Depression: Child-Driven and Bidirectional Effects.

Adolescent depression can be a stressor for parents and families. This study evaluated how treating adolescent depression affects marital and parent-child relationships. We examined whether marital adjustment and parent-child conflict improved over the course of active treatment of depressed adolescents (36-week visit) and long-term follow-up (one year after discontinuation of treatment) in a sample of 322 clinically depressed youth participating in the Treatment for Adolescents with Depression Study (TADS). We also explored the bidirectional influences of adolescent depression and family relationships. Results indicated that marital adjustment was stable during active treatment but declined during long-term follow up. A structural equation model (SEM) examining the bidirectional relation between adolescent depression and marital adjustment indicated that higher adolescent depression at the conclusion of maintenance treatment (24-week visit) predicted a deterioration of marital adjustment at the end of active treatment (36-week visit). Parent-child conflict was unchanged during treatment and follow up. SEM analyses examining the bidirectional relationship between youth depression and parent-child conflict revealed that reduced depressive symptoms at the end of the active treatment period predicted improvement in parent-child conflict at subsequent time points. These findings suggest that youth depression and its treatment may influence long-term family functioning.

Cognitive-behavioral therapy for adolescent depression: a meta-analytic investigation of changes in effect-size estimates.

OBJECTIVE: To explicate differences between early and recent meta-analytic estimates of the effects of cognitive-behavioral therapy (CBT) for adolescent depression. METHOD: Meta-analytic procedures were used to investigate whether methodological characteristics moderated mean effect sizes among 11 randomized, controlled trials of CBT focusing on adolescents meeting diagnostic criteria for unipolar depression. RESULTS: Cumulative meta-analyses indicated that effects of CBT have decreased from large effects in early trials, and confidence intervals have become narrower. Effect sizes were significantly smaller among studies that used intent-to-treat analytic strategies, compared CBT to active treatments, were conducted in clinical settings, and featured greater methodological rigor based on CONSORT (Consolidated Standards of Reporting Trials) criteria. The mean posttreatment effect size of 0.53 was statistically significant. CONCLUSIONS: Differences in estimates of the efficacy of CBT for depressed adolescents may stem from methodological differences between early and more recent investigations. Overall, results support the effectiveness of CBT for the treatment of adolescent depression.

A manual-based intervention to address clinical crises and retain patients in the Treatment of Adolescents With Depression Study (TADS).

OBJECTIVE: To describe a manual-based intervention to address clinical crises and retain participants in the Treatment for Adolescents With Depression Study (TADS). METHOD: The use of adjunct services for attrition prevention (ASAP) is described for adolescents (ages 12-17 years) during the 12-week acute treatment in TADS, from 2000 to 2003. Logistic regression, controlling for site, was used to predict use. RESULTS: Of 439 enrolled participants, 17.8% (n = 78) used ASAP primarily for suicidality or worsening of depression. Of these, 46.2% continued in their assigned treatment through week 12, 47.4% received out-of-protocol treatment but continued participating in assessments, and 10.3% withdrew consent, including 3 who terminated treatment and withdrew consent on the same date. ASAP use did not differ between treatments (p =.97) and typically occurred early in treatment. At the end of the 12 weeks, 37.2% of participants using ASAP remained in their assigned treatment, although 80.8% continued participating in assessments. ASAP was associated with, at baseline, a higher severity of depression (p <.01), substance use (p <.01), and precontemplation level of change (p <.02). CONCLUSIONS: ASAP may be useful to retain adolescent participants and as a safety intervention in placebo-controlled trials. In clinical practice ASAP-like procedures may be useful to encourage adherence in patients engaging in long-term treatment. Clinical trial registration information-URL: http://www.clinicaltrials.gov. Unique identifier: NCT00006286.

Factors associated with recruitment and screening in the Treatment for Adolescents With Depression Study (TADS).

OBJECTIVE: To examine factors associated with eligibility and randomization and consider the efficiency of recruitment methods. METHOD: Adolescents, ages 12 to 17 years, were telephone screened (N = 2,804) followed by in-person evaluation (N = 1,088) for the Treatment for Adolescents With Depression Study. Separate logistic regression models, controlling for site, examined whether sex, age, race, or source of recruitment was associated with eligibility, providing written consent, or randomization. Efficiency was calculated from the number of completed telephone screens per each enrolled participant. RESULTS: Older adolescents were less likely to be eligible at telephone screening (odds ratio [OR] 0.81). Regardless of race, eligible adolescents who were referred by a professional had higher odds of presenting in-person for consent (OR 1.56). African Americans had statistically lower odds of providing consent (OR 0.67), particularly if recruited by advertisement (OR 0.54). Females were more likely to be diagnosed with major depressive disorder (OR 1.69). No significant differences were found between randomized participants and eligible adolescents who withdrew from the study before randomization. CONCLUSIONS: These findings underscore the importance of using multiple strategies to recruit adolescents for clinical trial participation and enhancing sensitivity to cultural variations, especially when reaching out to depressed African Americans.

Trajectories of Functioning Into Emerging Adulthood Following Treatment for Adolescent Depression.

PURPOSE: It is well established that empirically supported treatments reduce depressive symptoms for most adolescents; however, it is not yet known whether these interventions lead to sustained improvements in global functioning. The goal of this study is to assess the clinical characteristics and trajectories of long-term psychosocial functioning among emerging adults who have experienced adolescent-onset major depressive disorder. METHODS: Global functioning was assessed using the Clinical Global Assessment Scale for children (participants ≤18 years), the Global Assessment of Functioning (participants ≥ 19 years) and the Health of the Nation Outcome Scales for Adolescents among 196 adolescents who elected to complete 3.5 years of naturalistic follow-up subsequent to their participation in the Treatment for Adolescents with Depression Study. The Treatment for Adolescents with Depression Study examined the efficacy of cognitive behavior therapy, fluoxetine, and the combination of cognitive behavior therapy and fluoxetine (combination treatment) over the course of 36 weeks. Mixed-effects regression models were used to identify trajectories and clinical predictors of functioning over the naturalistic follow-up. RESULTS: Global functioning and achievement of developmental milestones (college, employment) improved over the course of follow-up for most adolescents. Depressive relapse, initial randomization to the placebo group, and the presence of multiple psychiatric comorbidities conferred risk for relatively poorer functioning. CONCLUSIONS: Functioning generally improves among most adolescents who have received empirically supported treatments. However, the presence of recurrent major depressive disorder and multiple psychiatric comorbidities is associated with poorer functioning trajectories, offering targets for maintenance treatment or secondary prevention.

Parental marital discord and treatment response in depressed adolescents.

Evidence suggests that parental marital discord contributes to the development of internalizing and externalizing symptoms in children and adolescents. Few studies, however, have examined the association between parental marital discord and youth's response to treatment. The present study examined the impact of interparental discord on treatment response in a randomized control trial of adolescents with major depression enrolled in the Treatment for Adolescents with Depression Study (TADS). Participants were 260 adolescents from two-parent households randomly assigned to one of four treatment groups: fluoxetine (FLX), cognitive behavior therapy (CBT), their combination (COMB), or placebo (PBO). Logistic regressions revealed that parental marital discord interacted with youth gender and co-morbid oppositionality symptoms to predict group differences in treatment response.

Randomized controlled trial of primary care physician motivational interviewing versus brief advice to engage adolescents with an Internet-based depression prevention intervention: 6-month outcomes and predictors of improvement.

We believe that primary care physicians could play a key role in engaging youth with a depression prevention intervention. We developed CATCH-IT (Competent Adulthood Transition with Cognitive Behavioral and Interpersonal Training), which is an adolescent Internet-based behavior change model. We conducted a randomized comparison of two approaches in engaging adolescents with the Internet intervention: primary care physician (PCP) motivational interview + CATCH-IT Internet program (MI) vs PCP brief advice + CATCH-IT Internet program (BA). The participants (N = 84) were recruited by screening for risk of depression in 13 primary care practices. We compared depressive disorder outcomes between groups and within groups over 6 months and examined the potential predictors and moderators of outcomes across both study arms. Depressive symptom scores declined from baseline to 6 weeks with these statistically significant reductions sustained at the 6 months follow-up in both groups. No significant interactions with treatment condition were found. However, by 6 months, the MI group demonstrated significantly fewer depressive episodes and reported less hopelessness as compared with the BA group. Hierarchical linear modeling regressions showed higher ratings of ease of use of the Internet program predicting lower depressive symptom levels over 6 months. In conclusion, a primary care/Internet-based intervention model among adolescents demonstrated reductions in depressed mood over 6 months and may result in fewer depressive episodes.
