Associations between Sex, Rumination, and Depressive Symptoms in Late Adolescence: A Four-Year Longitudinal Investigation.

OBJECTIVE: The literature on the association between sex, rumination, and depression indicates significant variability from childhood to adulthood. Although this variability indicates the need for a developmental lens, a surprising lack of research has been conducted on the association between these variables from middle to late adolescence. METHOD: The present study seeks to bridge this gap using structured equation modeling (SEM) to evaluate the reciprocal associations between sex, brooding rumination, reflective rumination, and depressive symptoms in a sample of students measured at 8th grade, 9th grade, and 12th grade time points. RESULTS: In line with findings across the lifespan, female participants indicated significantly higher average levels of both subtypes of rumination and depressive symptoms versus males. Novel results of this study include the findings that for male participants in this age range, brooding rumination predicted later depressive symptoms, while for female participants, early depressive symptoms predicted later brooding. For female participants, early reflective rumination predicted later depressive symptoms. CONCLUSIONS: This is the first investigation of its kind to demonstrate deleterious longitudinal effects of self-reflective rumination. Findings are interpreted through an ecological framework and mark the transition to high school as a potential risk for interrupted problem-solving of circumstances related to adolescents' distress.

Predictors and moderators of recurring self-harm in adolescents participating in a comparative treatment trial of psychological interventions.

BACKGROUND: In primary analyses, dialectical behavior therapy (DBT) was associated with greater reduction in self-harm during treatment than individual/group supportive therapy (IGST). The objective of this paper was to examine predictors and moderators of treatment outcomes for suicidal adolescents who participated in a randomized controlled trial evaluating DBT and IGST. METHODS: Adolescents (N = 173) were included in the intent-to-treat sample and randomized to receive 6 months of DBT or IGST. Potential baseline predictors and moderators were identified within four categories: demographics, severity markers, parental psychopathology, and psychosocial variables. Primary outcomes were suicide attempts (SA) and nonsuicidal self-injury evaluated at baseline, midtreatment (3 months), and end of treatment (6 months) via the Suicide Attempt and Self-Injury Interview (Psychological Assessment, 18, 2006, 303). For each moderator or predictor, a generalized linear mixed model was conducted to examine main and interactive effects of treatment and the candidate variable on outcomes. RESULTS: Adolescents with higher family conflict, more extensive self-harm histories, and more externalizing problems produced on average more reduction on SH frequency from baseline to post-treatment. Adolescents meeting BPD diagnosis were more likely to have high SH frequency at post-treatment. Analyses indicated significant moderation effects for emotion dysregulation on NSSI and SH. DBT was associated with better rates of improvement compared to IGST for adolescents with higher baseline emotion dysregulation and those whose parents reported greater psychopathology and emotion dysregulation. A significant moderation effect for ethnicity on SA over the treatment period was observed, where DBT produced better rate of improvement compared to IGST for Hispanic/Latino individuals. CONCLUSIONS: These findings may help to inform salient treatment targets and guide treatment planning. Adolescents that have high levels of family conflict, externalizing problems, and increased level of severity markers demonstrated the most change in self-harm behaviors over the course of treatment and benefitted from both treatment interventions. Those with higher levels of emotion dysregulation and parent psychopathology may benefit more from the DBT.

Emotion regulation processes linking peer victimization to anxiety and depression symptoms in adolescence.

Difficulties with emotion regulation can take many forms, including increased sensitivity to emotional cues and habitual use of maladaptive cognitive or behavioral regulation strategies. Despite extensive research on emotion regulation and youth adjustment, few studies integrate multiple measures of emotion regulation. The present study evaluated the underlying structure of emotion regulation processes in adolescence using both task- and survey-based measures and determined whether differences in these emotion regulation latent factors mediated the association between peer victimization and internalizing psychopathology. Adolescents aged 16-17 years (n = 287; 55% female; 42% White) recruited in three urban centers in the United States completed baseline and follow-up assessments 4 months apart. Three models of emotion regulation were evaluated with confirmatory factor analysis. A three-factor model fit the data best, including cognitive regulation, behavioral regulation, and emotional reactivity latent factors. Task-based measures did not load onto these latent factors. Difficulties with behavioral regulation mediated the association between peer victimization and depression symptoms, whereas cognitive regulation difficulties mediated the association with anxiety symptoms. Findings point to potential targets for intervention efforts to reduce risk for internalizing problems in adolescents following experiences of peer victimization.

Indicated Prevention for Depression at the Transition to High School: Outcomes for Depression and Anxiety.

This study examined the impact of a school-based indicated prevention program on depression and anxiety symptoms for youth during the transition from middle to high school. The High School Transition Program (HSTP) was designed to build social and academic problem-solving skills and engagement during this period of particular vulnerability for adolescents. Students (N = 2664) at six middle schools in the Pacific Northwest completed a universal emotional health screening during the second half of the 8th grade year, and those with elevated depression scores and low conduct problem scores were invited to participate in the trial. Eligible students (N = 497) were randomized to either the HSTP (N = 241) or control (N = 256) conditions. Depression and anxiety symptoms were measured at five time points over an 18-month period using validated self-report measures. Hierarchical linear modeling was used to assess prevention effects and moderators such as baseline symptoms, race, and sex. Results suggested that students randomized to the HSTP group had accelerated rate of reduction in depressive symptoms over time (d = .23) relative to the control group. Students randomized to the HSTP group also had significantly faster rates of change of anxiety scores (d = 0.25). Baseline anxiety severity, race, and sex did not differentially impact the trajectories of symptom outcomes between conditions. Implications for prevention efforts during this normative but stressful period of transition for youth are discussed. ClinicalTrials.gov registration number is NCT00071513.

Research strategy for health sciences: Facebook friend request is non-differentially accepted in a diverse, young adult population.

Social media is being used for recruitment and the study of health-care choices and behavior, and could be particularly helpful to reach young adult populations outside of a 4 year college setting. The aim of this study was to report on overall success of recruiting young adults in diverse settings with respect to education and employment into a study using Facebook (FB). Young adults (n = 380, 50% male, 44% white) who had been involved in a longitudinal research project received a friend request from the research study group's profile. Acceptance rates of friend requests and sociodemographic and mental health factors associated with acceptance were evaluated. Approximately 67% of 318 participants who received a friend request accepted the request. Sociodemographic and mental health characteristics were similar between those who did and did not accept friend requests, suggesting non-differential recruitment through FB. Friending through FB is a feasible way to reach young adults involved in health and behavioral research, and could be a way to expand the populations that are studied in health science research to maximize generalizability of the conclusions drawn.

Parental Validation and Invalidation Predict Adolescent Self-Harm.

This study was designed to evaluate family processes theoretically implicated in the onset and maintenance of adolescent self-harm. In the present study, we focus on understanding parental validation and invalidation in response to their adolescent in order to estimate the association between parental responses and self-harm in a high risk group of adolescents. We also sought to determine the influence of psychotherapy on parental validation and invalidation over time during participation in a randomized clinical trial of psychotherapy designed to reduce self-harm. Thirty-eight teens (M age= 14.85; 94.1% female, 55.3% Caucasian, and 17.5% Latino) and their parents participated in three assessments over a six month period corresponding to pretreatment, midtreatment and end of treatment in the trial. Results indicate a robust association between parental validation, invalidation and adolescent self-harm. There were no significant associations observed between parental validation, invalidation, and adolescent suicidal ideation. Observed levels of parental validation and invalidation were not changed during the six-month course of psychotherapy.

Suicidal ideation in early to middle adolescence: sex-specific trajectories and predictors.

BACKGROUND: The present study examined developmental trajectories of suicidal ideation (SI) and predictors of the course of SI across early to middle adolescence in a sample of 521 children utilizing a prospective longitudinal design. METHOD: A baseline assessment including structured interviews and parent- and adolescent-reported measures was conducted at age 11-12 years, with follow-up assessments occurring 6, 12, 18, and 36 months later. RESULTS: Group-based trajectory analyses revealed three groups of individuals, one group that remained at low ideation scores throughout the time period examined, another group with moderate ideation scores and a minority of children who had fluctuating SI. Sex differences in SI trajectories were revealed with the highest SI scores at age 12 for boys. For boys in this group, high ideation followed by a steady decline in the slope over time. SI in girls demonstrated a quadratic function increasing from age 12 to 13, and decreasing from age 14 to 15. Factors that predicted SI group membership were identified. Depression, externalizing problems, family and friend support discriminated SI trajectories for both boys and girls. History of a suicide attempt was associated with moderate- and high-declining ideation groups for boys, and moderate and high ideation group for girls. CONCLUSIONS: Assessment of SI in adolescents should occur in early adolescents, particularly around the time of school transitions.

The internalizing pathway to adolescent substance use disorders: mediation by ruminative reflection and ruminative brooding.

Two subtypes of rumination were examined in relationship to substance use and substance use disorders in adolescents. In the 8th and 9th grade, 521 adolescents completed measures assessing depressive symptoms, conduct problems, and reflective and brooding subtypes of rumination. In 12th grade, adolescents reported substance use and were administered the substance use disorders modules from the DISC. Path analyses conducted with data from 428 participants indicated that neither depression nor rumination variables significantly affected the presence of substance use. However, indirect effects of depression through reflection and brooding were differentially related to risk of developing substance use disorders, with brooding positively associated with Marijuana Use Disorders, and reflection negatively related to both Marijuana and Alcohol Use Disorders. Pathways did not differ by sex. These findings suggest that promoting self-reflection may be an effective strategy to prevent and intervene with the development of problematic substance use.

Remission, Recovery, Relapse, and Recurrence Rates for Suicide Attempts and Nonsuicidal Self-Injury for Suicidal Youth Treated With Dialectical Behavior Therapy or Supportive Therapy.

OBJECTIVE: To evaluate rates of remission, recovery, relapse, and recurrence in suicidal youth who participated in a clinical trial comparing Dialectical Behavior Therapy (DBT) and Individual and Group Supportive Therapy (IGST). METHOD: Participants were 173 youth, aged 12 to 18 years, with repetitive self-harm (including at least 1 prior suicide attempt [SA]) and elevated suicidal ideation (SI). Participants received 6 months of DBT or IGST and were followed for 6 months post-treatment. The sample was 95% female, 56.4% White, and 27.49% Latina. Remission was defined as absence of SA or nonsuicidal self-injury (NSSI) across one 3-month interval; recovery was defined across 2 or more consecutive intervals. Relapse and recurrence were defined as SA or NSSI following remission or recovery. Cross-tabulation with χ2 was used for between-group contrasts. RESULTS: Over 70% of the sample reported remission of SA at each treatment and follow-up interval. There were significantly higher rates of remission and recovery and lower rates of relapse and recurrence for SA in DBT than for IGST. Across treatments and time points, SA had higher remission and recovery rates and lower relapse and recurrence rates than NSSI. There were no significant differences in NSSI remission between conditions; however, participants receiving DBT had significantly higher NSSI recovery rates than those receiving IGST for the 3- to 9-month, 3- to 12-month, and 6- to 12-month intervals. CONCLUSION: Results showed higher percentages of SA remission and recovery for DBT as compared to IGST. NSSI was less likely to remit than SA. DIVERSITY & INCLUSION STATEMENT: We worked to ensure race, ethnic, and/or other types of diversity in the recruitment of human participants.

A unique model of care for youth in crisis: A pilot open trial.

Suicide is the second leading cause of death for those ages 10-24 years in the United States, and emergency department (ED) visits due to youth self-injurious thoughts and behaviors (SITB) and increased substantially between 2016 and 2021. Although ED services are essential for an effective system of care, the ED setting is typically not well-suited for the comprehensive, collaborative, and therapeutic evaluation of SITB; treatment planning; and care coordination that youth in a suicidal crisis need. As a result, an urgent care model for mental health designed to provide comprehensive crisis triage and intervention services is needed within outpatient psychiatry. This pilot trial examined the feasibility, acceptability, and preliminary clinical outcomes of a brief, urgent care model, the Behavioral Health Crisis Care Clinic (CCC), designed to provide comprehensive outpatient triage and intervention services aimed at reducing suicide risk for youth in crisis. Participants were 189 youth (ages 10-20; 62.4% females; 58% Caucasian) who had past-week suicidal ideation or behavior and their caregivers. The results demonstrated the CCC model exceeded feasibility and acceptability benchmarks based on the Service Satisfaction Scale (M score > 3.00). CCC care was associated with significant decreases in self-reported suicide risk based on the Collaborative Assessment and Management of Suicidality Suicide Status Form with low levels of ED usage during CCC care (7.7%) and 1-month posttreatment (11.8%). Over 88% of patients without established outpatient care at the time of referral were connected to care during CCC treatment, almost all of whom (95%) continued with ongoing mental health care 1 month after ending CCC care.

Suicide in young people: screening, risk assessment, and intervention.

Suicide is the fourth leading cause of death among young people worldwide and the third leading cause of death among those in the US. This review outlines the epidemiology of suicide and suicidal behavior in young people. It discusses intersectionality as an emerging framework to guide research on prevention of suicide in young people and highlights several clinical and community settings that are prime targets for implementation of effective treatment programs and interventions aimed at rapidly reducing the suicide rate in young people. It provides an overview of current approaches to screening and assessment of suicide risk in young people and the commonly used screening tools and assessment measures. It discusses universal, selective, and indicated evidence based suicide focused interventions and highlights components of psychosocial interventions with the strongest evidence for reducing risk. Finally, the review discusses suicide prevention strategies in community settings and considers future research directions and questions challenging the field.

Advancing Suicide Intervention Strategies for Teens (ASSIST): study protocol for a multisite randomised controlled trial.

INTRODUCTION: Brief interventions that reduce suicide risk following youth's experience with acute care due to suicidality are needed. METHODS AND ANALYSIS: The study will use a three-arm randomised controlled trial designed to test the effectiveness of the Safety Planning Intervention with structured follow-up (SPI+) and the Collaborative Assessment and Management of Suicidality (CAMS) compared with enhanced usual care. The primary outcomes measure will be suicidal events, defined as death by suicide, attempted suicide, preparatory acts toward imminent suicidal behaviour or suicidal ideation resulting in a change in emergency evaluation or inpatient admission. Secondary measures will be the number of suicide attempts and severity of suicidal ideation. The experimental interventions, SPI+ and CAMS, consist of up to eight sessions over approximately 8 weeks that are designed to manage (SPI+) or treat (CAMS) patient-identified 'drivers' of suicidal thoughts and behaviours. Mechanisms and moderators of change will be evaluated to understand treatment impacts. ETHICS AND DISSEMINATION: This study has been approved by the Seattle Children's Institutional Review Board and is monitored by external agencies including the University of Washington Institute for Translational Health Sciences, and a National Institute of Mental Health (NIMH)-appointed Data Safety and Monitoring Board. Trial results will help establish evidence towards safe and effective treatment strategies for youth transitioning from acute to outpatient care due to a suicidal crisis. The data will be shared with the NIMH Data Archives and disseminated through publications and conferences. TRIAL REGISTRATION NUMBER: NCT05078970.

The Patient-Reported Outcomes Measurement Information System (PROMIS) pediatric and parent-proxy short forms for anxiety: Psychometric properties in the Kids FACE FEARS sample.

There is tremendous need for brief and supported, non-commercial youth- and caregiver-report questionnaires of youth anxiety. The pediatric and parent proxy short forms of the Patient-Reported Outcomes Measurement Information System (PROMIS) Anxiety scale (8a v2.0) are free, brief, publicly accessible measures of youth- and caregiver-reported anxiety in children and adolescents. Despite increased use of the PROMIS, no study has evaluated performance of its anxiety scales in a sample of treatment-engaged anxious youth. Analyses were conducted on baseline data from the first 265 families (child MAge=11.14 years, 70% racial/ethnic minoritized youth) to enroll in the Kids FACE FEARS trial, a multisite comparative effectiveness trial of therapist-led vs. self-administered treatment for elevated youth anxiety. Confirmatory factor analysis (CFA) examined factor structure; omega coefficients and regression models examined internal consistency, convergent validity, and cross-informant reliability. CFA supported adjusted single-factor solutions across youth and caregiver reports, and internal consistency was high. Convergent validity was supported by medium-to-large associations with anxiety-related impairment and severity. Moderate cross-informant reliability between reports was found. Results showcase the first psychometric study of the PROMIS Anxiety scale short forms among treatment-engaged youth with elevated anxiety. Findings highlight the PROMIS Anxiety scale's utility in typical care settings for youth anxiety.

Trajectories of Treatment Response and Nonresponse in Youth at High Risk for Suicide.

OBJECTIVE: To examine trajectories of treatment response in suicidal youth who participated in a randomized controlled trial comparing dialectical behavior therapy (DBT) and individual and group supportive therapy. METHOD: Using latent class analysis across both treatment conditions, secondary analyses were conducted of data from a multisite randomized controlled trial comprising 173 youths ages 12-18 with repetitive self-harm (SH) (including ≥1 lifetime suicide attempts) and elevated suicidal ideation (SI). The sample was 95% female, 56.4% White, and 27.49% Latina. Participants received 6 months of DBT or individual and group supportive therapy and 6 months of follow-up. Primary outcomes were SH and SI. RESULTS: Of the sample, 63% and 74% were members of latent classes that showed improvement in SI and SH, respectively; 13% were total nonresponders, with no improvement in SI or SH. SH nonresponse emerged at the midpoint of treatment (3 months), with nonresponders showing a sharp increase in SH over the remainder of treatment and follow-up. Youth receiving DBT were significantly more likely to be an SH responder vs nonresponder than youths in individual and group supportive therapy (ꭓ21 = 6.53, p = .01). An optimal threshold cut point using multivariate predictors of total nonresponse (White, externalizing symptoms, total SH, and SI) predicted total nonresponders to DBT with 100% accuracy. CONCLUSION: This is the first study to identify trajectories of both SI and SH response to treatment in a sample of adolescents at risk of suicide. Results may inform personalized treatment approaches. CLINICAL TRIAL REGISTRATION INFORMATION: Collaborative Adolescent Research on Emotions and Suicide (CARES); https://www.

Methodological implications of the affect revolution: a 35-year review of emotion regulation assessment in children.

This investigation analyzed the methods used over the past 35 years to study emotion regulation (ER) in children. Articles published from 1975 through 2010 were identified in 42 child clinical, developmental, and emotion psychology journals. Overall, 61.1% of published ER articles relied on one method and 23.6% used two methods. Analyses revealed (a) 82.8% of published ER research occurring within the past decade; (b) higher rates of observational methods with infant and toddler/preschool samples, but more use of self-report methodology with middle childhood and adolescent samples; (c) a longer history of published ER research with samples of infants to 5-year-olds, including the use of more longitudinal design, compared with older samples; and (d) a positive association between journal impact ratings and the use of physiological and observational measurement. Review of the measurement tools used to capture ER revealed great diversity in how emotion processes are understood and evaluated.

Collaborative Assessment and Management of Suicidality for Teens: A Promising Frontline Intervention for Addressing Adolescent Suicidality.

This pilot open trial examined the feasibility, acceptability, and preliminary outcomes of the Collaborative Assessment and Management of Suicidality for teens (CAMS-4Teens) who presented to outpatient care with suicidal thoughts and behaviors. Participants were 22 adolescents (13-17; 59% identified as female) with clinical elevations (≥7) on the Suicidal Behaviors Questionnaire-Revised (SBQ-R). Primary outcomes were feasibility and acceptability. We also explored outcomes of suicidal thoughts and behaviors, as well as mixed effects modeling for weekly assessments of the Suicide Status Form (SSF) Core Assessment constructs. Our main implementation outcomes suggest that the intervention is acceptable, appropriate, and feasible to deliver. Clinicians were adherent to the model with high ratings of adherence. In addition, preliminary evaluation of suicidal thoughts and behaviors found a large effect size for reduction in suicidal thoughts. Benchmarking to other adolescent suicide specific interventions and the Collaborative Assessment of Management of Suicidality with adult populations provide promise that suicidal adolescent responses may be on par with established interventions. Findings from the study are preliminary in nature and intended to inform if CAMS with adolescents is a promising approach to engage and treat patient-defined "drivers" of suicide. The results suggest that a future investigation with power to detect significant change over another active intervention is warranted.

Displayed Depression Symptoms on Facebook at Two Time Points: Content Analysis.

BACKGROUND: Depression is a prevalent and problematic mental disorder that often has an onset in adolescence. Previous studies have illustrated that depression disclosures on social media are common and may be linked to an individual's experiences of depression. However, most studies have examined depression displays on social media at a single time point. OBJECTIVE: This study aims to investigate displayed depression symptoms on Facebook at 2 developmental time points based on symptom type and gender. METHODS: Participants were recruited from an ongoing longitudinal cohort study. The content analysis of text-based Facebook data over 1 year was conducted at 2 time points: time 1 (adolescence; age 17-18 years) and time 2 (young adulthood; ages 20-22 years). Diagnostic criteria for depression were applied to each post to identify the displayed depression symptoms. Data were extracted verbatim. The analysis included nonparametric tests for comparisons. RESULTS: A total of 78 participants' Facebook profiles were examined, of which 40 (51%) were male. At time 1, 62% (48/78) of the adolescents had a Facebook profile, and 54% (26/78) displayed depression symptom references with an average of 9.4 (SD 3.1) references and 3.3 (SD 2.3) symptom types. Of the 78 participants, 15 (19%) females and 12 (15%) males displayed depression symptom references; these prevalence estimates were not significantly different by gender (P=.59). At time 2, 35 young adults displayed symptoms of depression with an average of 4.6 (SD 2.3) references and 2.4 (SD 1.3) symptom types. There were no differences in the prevalence of symptoms of depression displayed between males (n=19) and females (n=16; P=.63). CONCLUSIONS: This content analysis study within an ongoing cohort study illustrates the differences in depression displays on Facebook by developmental stage and symptom. This study contributes to a growing body of literature by showing that using social media to observe and understand depression during the emerging adult developmental period may be a valuable approach.

Dialectical Behavior Therapy for Suicidal Self-Harming Youth: Emotion Regulation, Mechanisms, and Mediators.

OBJECTIVE: This study evaluated mechanisms, mediation, and secondary/exploratory outcomes in our randomized controlled trial evaluating dialectical behavior therapy (DBT) compared to individual and group supportive therapy (IGST). We expand on previously reported results indicating a DBT advantage at posttreatment on planned suicide/self-harm outcomes, and greater self-harm remission (absence of self-harm, post hoc exploratory outcome) during active-treatment and follow-up periods. METHOD: This was a multi-site randomized trial of 173 adolescents with prior suicide attempts, self-harm, and suicidal ideation. Randomization was to 6 months of DBT or IGST, with outcomes monitored through 12 months. Youth emotion regulation was the primary mechanistic outcome. RESULTS: Compared to IGST, greater improvements in youth emotion regulation were found in DBT through the treatment-period [t(498) = 2.36, p = .019] and 12-month study period (t(498) = 2.93, p = .004). Their parents reported using more DBT skills: posttreatment t(497) = 4.12, p < .001); 12-month follow-up t(497) = 3.71, p < .001). Mediation analyses predicted to self-harm remission during the 6- to 12-month follow-up, the prespecified outcome and only suicidality/self-harm variable with a significant DBT effect at follow-up (DBT 49.3%; IGST 29.7%, p = .013). Improvements in youth emotion regulation during treatment mediated the association between DBT and self-harm remission during follow-up (months 6-12, estimate 1.71, CI 1.01-2.87, p = .045). Youths in DBT reported lower substance misuse, externalizing behavior, and total problems at posttreatment/6 months, and externalizing behavior throughout follow-up/12 months. CONCLUSION: Results support the significance of emotion regulation as a treatment target for reducing self-harm, and indicate a DBT advantage on substance misuse, externalizing behavior, and self-harm-remission, with 49.3% of youths in DBT achieving self-harm remission during follow-up.

Medically Treated Self-Injury Among Children and Adolescents: Repeated Attempts and Service Use Over 1 Year.

OBJECTIVE: Clinical, demographic, and service use patterns of youths ages 6-18 years who had a medically treated self-injury were examined to understand factors associated with recurrence of such an injury in the subsequent year. METHODS: This retrospective cohort analysis used data from 31,147 youths who were medically treated for self-injury. Data were from IBM/Watson MarketScan commercial claims and encounters databases (2007-2016). The index self-injury was defined as the first event with an ICD code related to self-injury or suicidal ideation combined with a wound code. Cox proportional hazards regression was used to determine the hazard ratios and 95% confidence intervals (CIs) describing associations with subsequent medically treated self-injury for youths who were hospitalized in psychiatric facilities in the seven days before or after the index self-injury versus those who were not. RESULTS: Approximately 2% of the 31,147 youths had another medically treated self-injury in the year following the index self-injury. The hospitalized group had higher service use in the years prior to and following their self-injury, but the mean number of outpatient psychiatric visits before the index self-injury did not differ significantly between groups. Hazard ratios for clinical, demographic, and service use variables indicated that those who were hospitalized in psychiatric facilities for the index event were twice as likely (95% CI=1.7-2.7) as those who were not to have another medically treated self-injury in the year after the index event. CONCLUSIONS: In this retrospective, observational study, psychiatric hospitalization after self-injury was strongly associated with recurrence of self-injury in the subsequent year.

Mechanisms of Change in the Prevention of Depression: An Indicated School-Based Prevention Trial at the Transition to High School.

OBJECTIVE: Depression represents a major public health concern, and prevalence increases significantly during adolescence. The high school transition may exacerbate the risk of depression for youth with pre-existing vulnerability. The High School Transition Program (HSTP) is a brief, skills-based intervention that has demonstrated efficacy in preventing depression in adolescents. The current study aimed to evaluate the theorized mechanisms of change of the HSTP intervention by testing a multiple mediation model including school attachment (SA) and self-esteem (SE) as two mediators of treatment outcomes. METHOD: Students (N= 497; 61.5% girls) with elevated depressive symptoms, identified for the intervention program via an eighth-grade screening, were randomized to a brief intervention (n = 247) or the HSTP (n = 233) from 2003 to 2008. Participants completed measures at five time points. The first assessment occurred at the start of the second semester of eighth grade and the last assessment occurred at the end of ninth grade. A multiple mediation model tested whether SA and SE contributed to changes in depression for youth in the HSTP. RESULTS: The mediation model, including contemporaneously assessed SE and SA, was not supported. There was evidence of sequential mediation, such that students who participated in the HSTP intervention reported higher SA, which in turn predicted improved SE, and in turn contributed to amelioration of depressive symptoms. CONCLUSION: The HSTP intervention ameliorated depressive symptoms by targeting factors specific to the school transition (ie, SA). Results suggest youth at risk for depression may benefit from prevention efforts that enhance students' capacity to effectively manage identified environmental stressors, such as school transitions.
