Peer-adult network structure and suicide attempts in 38 high schools: implications for network-informed suicide prevention.

BACKGROUND: Strengthening social integration could prevent suicidal behavior. However, minimal research has examined social integration through relationship network structure. To address this important gap, we tested whether structural characteristics of school networks predict school rates of ideation and attempts. METHODS: In 38 US high schools, 10,291 students nominated close friends and trusted adults to construct social networks. We used mixed-effects logistic regression models to test individual student networks and likelihood of suicidal ideation (SI) and suicide attempts (SA); and linear regression models to estimate associations between school network characteristics and school rates of SI, SA, and SA among all with ideation. RESULTS: Lower peer network integration and cohesion increased likelihood of SI and SA across individual and school-level models. Two factors increased SA: student isolation from adults and suicidal students' popularity and clustering. A multivariable model identified higher SA in schools where youth-adult relationships were concentrated in fewer students (B = 4.95 [1.46, 8.44]) and suicidal students had higher relative popularity versus nonsuicidal peers (B = 0.93 [0.10, 1.77]). Schools had lower SA rates when more students named the same trusted adults named by friends and many students named the same trusted adults. When adjusting for depression, violence victimization and bullying, estimates for adult network characteristics were substantially unchanged whereas some peer effects decreased. CONCLUSIONS: Schoolwide peer and youth-adult relationship patterns influence SA rates beyond individual student connections. Network characteristics associated with suicide attempts map onto three theory-informed domains: social integration versus thwarted relational needs, group cohesion, and suicidal students' social influence. Network interventions addressing these processes, such as maximizing youth-adult connections schoolwide and heightening influence of youth with healthy coping, could create more protective schools. Longitudinal and intervention studies are needed to determine how schools differentiate in network structure and clarify reciprocal dynamics between network characteristics and suicidal behavior.

Diffusion of a Peer-Led Suicide Preventive Intervention Through School-Based Student Peer and Adult Networks.

Background: Peer-led interventions have been applied to prevent various health behavior problems and may be an important complement to individual-level suicide prevention approaches. Sources of Strength trains student "peer leaders" in secondary schools to conduct prevention activities that encourage other students to build healthy social bonds and strengthen help-seeking norms. Prior work examining diffusion of peer-led programs has focused on youths' closeness to peer leaders but minimally on other factors such as connections to adults and suicidal behavior. Methods: We examined implementation and dissemination of Sources of Strength in 20 schools. Over 1 year 533 students were trained as peer leaders and 3,730 9th-12th graders completed baseline surveys assessing friendships and adults at school, and suicidal thoughts/behaviors; and end-of-year surveys reporting intervention exposure: viewed poster/video, attended presentation, direct peer communication, and activity participation. Chi-square tests compared exposure rates by student and network characteristics. Multi-level logistic regression models tested predictors of exposure across individual and school-level characteristics. Results: Exposure to the intervention varied greatly by school and by individual student characteristics and network position. Training more peer leaders increased school-wide exposure for all modalities except presentation (Bs 0.06-0.10, p's < 0.05). In multivariate models, exposure was consistently higher for students closer to peer leaders in the friendship network (ORs 1.13-1.54, p's < 0.05) and students who named more trusted adults (ORs 1.08-1.16, p's < 0.001); and lower for males (ORs 0.56-0.83, p's < 0.05). In multivariate models, training more students as peer leaders predicted exposure to poster-video and direct peer communication in larger schools (OR = 3.34 and 2.87, respectively). Network characteristics influenced exposure similarly for students with suicidal thoughts and behaviors. Discussion: Our findings confirm prior work showing the importance of personal affiliations to peer leaders and natural networks as a medium for diffusion of peer-led prevention efforts. We build on that work by showing independent effects of closeness to adults at school and number of peer leaders trained. There is a need to strategically select peer leaders to maximize closeness to students school-wide, particularly in larger schools. Additional work is required for Sources of Strength to devise messaging strategies to engage males and students isolated from adults at school.

Spanish translation and validation of the Interpersonal Needs Questionnaire.

The present study reports the multistage development and evaluation of a Spanish translation of the Interpersonal Needs Questionnaire (INQ). The INQ measures the constructs of thwarted belongingness and perceived burdensomeness, which the interpersonal theory of suicide proposes are proximal causes of suicidal desire. Participants were bilingual Hispanic college students in the United States (n = 56), heritage Spanish-speaking college students in the United States (n = 281), college students in Spain (n = 1,016), psychiatric inpatients in Mexico (n = 181), college students in Mexico (n = 239), and Spanish-speaking U.S. adults (n = 104). Results indicated that a 9-item 2-factor solution (INQ-S-9) provided good fit. Multiple group analyses were also consistent with measurement invariance across nationalities and clinical severity. Finally, both subscale scores demonstrated good internal consistency, test-retest reliability, convergent validity, and concurrent associations with scores on measures of suicide ideation. Cultural considerations and implications for use in clinical and research settings are discussed. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

Investigating Longitudinal Associations Between Sexual Assault, Substance Use, and Delinquency Among Female Adolescents: Results From a Nationally Representative Sample.

PURPOSE: Few studies have explored relations among sexual assault and prospective development of high-risk behaviors among adolescent girls. METHODS: The present study examined longitudinal associations among child sexual assault (CSA) and high-risk behaviors (nonexperimental alcohol and drug use; delinquent behavior) in a nationally representative sample of adolescent girls aged 12-17. RESULTS: Using path modeling, findings provided support for the link between CSA and nonexperimental alcohol use, drug use, and delinquent behavior after controlling for demographic characteristics and Time 1 functioning. Additionally, past 6-month post-traumatic stress disorder assessed at Time 1 was significantly associated with CSA and delinquency measured at Time 2, although the indirect effects did not reach traditional levels of significance. CONCLUSIONS: These findings suggest that CSA may potentiate risk for a number of public health problems.

Reactive Aggression and Suicide-Related Behaviors in Children and Adolescents: A Review and Preliminary Meta-Analysis.

The empirical literature on the association between reactive aggression and suicide-related behaviors in children and adolescents was reviewed. A narrative review of seven studies that met inclusion/exclusion criteria is followed by a preliminary meta-analysis to provide insight into the strength of the association between reactive aggression and suicide-related behaviors. Each of the seven studies reported a statistically significant association between reactive aggression and suicide-related behaviors, including suicide, nonfatal suicide attempt, and suicide ideation. Results from the meta-analysis indicated a consistent, medium-sized association (k = 7; N = 4,693; rbar = .25). The narrative review and results of the preliminary meta-analysis support the promise of pursuing future research on reactive aggression and suicide-related behaviors in children and adolescents. A theoretical model is proposed to guide the development of future research.

Reward Responsivity in Parenting: Development of a Novel Measure in Mothers of Young Children.

The purpose of the current study was to develop and evaluate a measure of maternal reward responsivity in parenting. Deficits in reward responsivity, a common feature of depression, may contribute to maladaptive parenting behaviors. Reward responsivity is an individual difference in reactivity to pleasurable stimuli and represents a key motivational component that could contribute to the frequency and quality of mothers' interactions with their infants. However, there is currently no measure of reward responsivity in parenting, which would be necessary to evaluate the link between mother reward responsivity, behaviors towards their infant, and infant behavior. Therefore, the current study reports on the development and initial evaluation of a self-report measure of reward responsivity in parenting, the Mother Inventory of Reward Experience (MIRE). We evaluated the MIRE among 200 mothers (M =28.45, SD = 5.50) recruited from a pediatric primary care center. After item analysis, 22 items were retained and displayed high internal consistency reliability and test re-test reliability. Convergent validity was established via a significant correlation with global reward responsivity. Concurrent validity was established via significant correlations with depressive symptoms, parenting stress, and child behavior problems. Incremental validity of the MIRE over a measure of global reward responsivity was supported. These results support the reliability and validity of the MIRE as a measure of reward responsivity in parenting.

Development and Open Trial of a Depression Preventive Intervention for Adolescents With Attention-Deficit/Hyperactivity Disorder.

Adolescents with attention-deficit/hyperactivity disorder (ADHD) are at elevated risk for experiencing unipolar depressive symptoms and disorders. The current study describes the development of a behaviorally oriented depression preventive intervention tailored for adolescents with ADHD targeting variables empirically shown to mediate ADHD and depression (i.e., reward responsivity, emotion regulation, and family support). Eight adolescents with a history of ADHD and currently elevated depressive symptoms and their parents participated in an open trial of the Behaviorally Enhancing Adolescents' Mood (BEAM) program. Adolescents and their parents reported high satisfaction with BEAM. Staff reported BEAM was easy to implement with high adherence. Following BEAM, there were significant reductions in parent-report of adolescents' depressive symptoms and emotion regulation at posttreatment and the 6-week follow-up and adolescent-report of reward responsivity at posttreatment. Case vignettes are also provided to illustrate implementation of the BEAM program. In spite of the small sample, lack of a control group, and some discrepancies across informants, results overall support the feasibility and acceptability of the BEAM program, and suggest it has promise in reducing depressive symptoms in adolescents with ADHD.

Aggressive Behaviors and Suicide Ideation in Inpatient Adolescents: The Moderating Roles of Internalizing Symptoms and Stress.

The present study examined a conceptual model in which the association between aggressive behaviors and suicide ideation is moderated by internalizing symptoms and ongoing stress. Participants were 304 psychiatric inpatient adolescents (65.8% girls) ranging in age from 12 to 17 years (Mean age = 14.69). The association between aggressive behaviors and suicide ideation was significantly moderated by internalizing symptoms and ongoing stress; the association was positive in adolescents low in internalizing symptoms or high in ongoing stress, but negative in adolescents high in internalizing symptoms or low in ongoing stress. The three-way interaction between aggressive behaviors, internalizing symptoms, and ongoing stress was not statistically significant. The current findings indicate that in adolescents who display high levels of aggressive behaviors, the presence of high ongoing stress provides a more useful indicator of levels of suicide ideation than the presence of high internalizing symptoms. Implications for case identification and prevention are discussed.

The effect of preterm birth on infant negative affect and maternal postpartum depressive symptoms: A preliminary examination in an underrepresented minority sample.

OBJECTIVE: To examine the effect of preterm birth on maternal postpartum depressive symptoms and infant negative affect in an underrepresented minority sample. METHOD: Participants were 102 mothers and their 3- to 10-month-old infants. Mothers completed the Edinburgh Postnatal Depression Scale and the Infant Behavior Questionnaire-Revised. RESULTS: Relative to normative samples, the current underrepresented minority sample of mostly Hispanics and Blacks displayed high rates of preterm birth (30%) and maternal postpartum depressive symptoms (17%). Preterm birth had a significant direct effect on postpartum depressive symptoms and infant negative affect. Additionally, there was an indirect effect of postpartum depressive symptoms on the relation between preterm birth and infant negative affect. Specifically, lower birth weight and gestational age predicted higher levels of depressive symptoms in the mother, and higher levels of depressive symptoms in the mother, in turn, predicted higher levels of infant negative affect. CONCLUSION: Findings emphasize the importance of screening for postpartum depressive symptoms and infant negative affect among mothers and their preterm infants, especially among families from underrepresented minority backgrounds.

Perceived benefits and proposed solutions for teen pregnancy: qualitative interviews with youth care workers.

The purpose of this article is to examine youth care workers' perceptions of the specific and unique sexual health needs of youth at risk for foster care. Semistructured interviews were conducted with youth care workers (N = 10) at a shelter for youth in or at risk for foster care. Youth care workers perceive that youth have unique experiences and needs related to sexual health programming and pregnancy prevention. Reflecting a great deal of family dysfunction, 3 themes emerged that revealed perceived benefits of teen pregnancy: youths' effort to prove themselves as adults, opportunity to secure their relationship with a partner, and desire to create an emotional connection with a baby. Lack of knowledge and accumulation of risk factors were viewed as most problematic. Current pregnancy prevention programs assume teen pregnancies are unwanted and emphasize the costs of sexual risk taking. Current findings suggest that sexual health programming for youth in or at risk for foster care should account for 3 perceived benefits of teen pregnancy. New opportunities for improving the reach and effectiveness of intervention for youth in or at risk for foster care are discussed.

Factor structure and psychometric properties of english and spanish versions of the edinburgh postnatal depression scale among Hispanic women in a primary care setting.

BACKGROUND: Although a number of studies have examined the factor structure of the Edinburgh Postnatal Depression Scale (EPDS) in predominately White or African American samples, no published research has reported on the factor structure among Hispanic women who reside in the United States. OBJECTIVE: The current study examined the factor structure of the EPDS among Hispanic mothers in the United States. METHOD: Among 220 Hispanic women, drawn from a pediatric primary care setting, with an infant aged 0 to 10 months, 6 structural models guided by the empirical literature were evaluated using confirmatory factor analysis. RESULTS: Results supported a 2-factor model of depression and anxiety as the best fitting model. Multigroup models supported the factorial invariance across women who completed the EDPS in English and Spanish. CONCLUSION: These findings provide initial support for the 2-factor structure of the EPDS among Hispanic women in the United States.

Is liability to recurrent major depressive disorder present before first episode onset in adolescence or acquired after the initial episode?

Many individuals who experience a major depressive episode will subsequently develop recurrent episodes. Although numerous studies have investigated predictors of recurrent episodes, methodological limitations have made it difficult to determine the extent to which liability to recurrent major depressive disorder (rMDD) exists prior to first onset or develops after first onset. This study used a prospective design in a community sample of adolescents to examine variables before and after first onset MDD as predictors of rMDD over a 12-year follow-up. Among 59 adolescents who experienced first onset MDD, 72.88% developed rMDD during the follow-up period. Parental history of rMDD and lifetime history of minor depression prior to MDD onset significantly predicted rMDD. These two effects replicated in ancillary analyses in an expanded sample of N = 205. Following MDD onset, a higher number of major life events significantly predicted rMDD. Liability to rMDD exists prior to MDD onset in the form of familial risk and less severe mood disturbances, whereas liability to rMDD in the form of elevated stress may develop following a first onset in adolescence.

Are reports of life event stress among suicidal youth subject to cognitive bias?

Severity of depressive symptoms, hopelessness, and suicidal ideation were examined to determine whether they were significantly associated with the accuracy of suicidal adolescents' ratings of stressful life events. The sample included 130 inpatient adolescents who endorsed suicide-related behaviors. Stress interviews were administered, and the severity of stressful events was rated separately by adolescents and an independent team. A residualized cognitive bias score was created by regressing adolescents' severity ratings to the independent team's severity ratings of the same events. Depressive symptoms, but not hopelessness or suicidal ideation, were significantly associated with cognitive bias scores. A negative cognitive bias in adolescents' reports of life stress may be present at higher levels of depression relative to minimal levels of depression. Further research on the relations between stress and suicide-related behaviors is encouraged to include independent ratings of stress severity.
