Effectiveness of the family-based model of dialectical behavior therapy for both suicidal adolescents and young adults in an academic medical center.

BACKGROUND: Dialectical behavior therapy (DBT) is an effective approach to decreasing suicidal behaviors; the adapted, family-based model for adolescents (through 18 years old; DBT-A) also demonstrates efficacy. Data on higher dropout rates based on age, initial research on DBT with young adults in the community, and the theory that underlies DBT suggest that adaptations may also be appropriate for young adults. This study examines the effectiveness of DBT-A, presents preliminary data on delivering DBT-A to young adults (ages 18-26), and compares clinical characteristics, service utilization, and outcomes to adolescent clients (ages 13-17) to guide clinical considerations and future research on implementing DBT-A. METHODS: Data were collected from a DBT-A clinic and included results from semi-structured diagnostic interviews, chart review, and scores on self-report measures. The Suicide Ideation Questionnaire and Beck Depression Inventory (BDI), given at program entry, after completion of one rotation through the skills modules, and at graduation, were used to evaluate outcomes. Outcomes were benchmarked against prior DBT-A trials. Adolescents' and young adults' clinical characteristics, service utilization, and outcomes were compared. RESULTS: The effect size observed was smaller than in efficacy trials. Few differences were observed between teens (n = 87) and young adults (n = 45). Young adults were more likely to have participated in intensive services before DBT-A. They participated in fewer family sessions and graduated in fewer months compared to teens. CONCLUSION: This study supports the use of the family-based model of DBT for suicidal teens and young adults although future research is needed to improve the effectiveness of this model when implemented in real-world settings.

Stress and smoking in adolescence: a test of directional hypotheses.

The authors conducted a comparative test of the hypotheses that (a) stress is an etiological factor for smoking and (b) cigarette smoking causes increases in stress (A. C. Parrott, 1999). Participants were a sample of 1,364 adolescents, initially surveyed at mean age 12.4 years and followed at 3 yearly intervals. Measures of negative affect, negative life events, and cigarette smoking were obtained at all 4 assessments. Latent growth modeling showed negative affect was related to increase in smoking over time; there was no path from initial smoking to change in negative affect. Comparable results were found for negative life events, with no evidence for reverse causation. Results are discussed with respect to theoretical models of nicotine effects and implications for prevention.

Moderators of the relation between substance use level and problems: test of a self-regulation model in middle adolescence.

The authors tested predictions, derived from a self-regulation model, about variables moderating the relationship between level of substance use (tobacco, alcohol, and marijuana) and problems associated with use. Data were from two independent studies of adolescents, with mean ages of 15.4 and 15.5 years (Ns = 1,699 and 1,225). Factor analysis indicated correlated dimensions of control problems and conduct problems. Protective moderation was found for variables indexing good self-control; risk-enhancing moderation was found for variables indexing poor self-control. These effects were generally independent of deviance-prone attitudes and externalizing symptomatology. Multiple-group structural modeling indicated moderation occurred for paths from life stress and coping motives and for paths from level to control and conduct problems. Moderation effects were also found for parental variables, peer variables, and academic competence.

Buffering effect of religiosity for adolescent substance use.

This research examined the hypothesis that religiosity buffers the impact of life stress on adolescent substance use. Data were from a sample of 1,182 participants surveyed on 4 occasions between 7th grade (mean age = 12.4 years) and 10th grade. Religiosity was indexed by Jessor's Value on Religion Scale (R. Jessor & S. L. Jessor, 1977). Zero-order correlations showed religiosity inversely related to alcohol, tobacco, and marijuana use. Significant Life Events x Religiosity buffer interactions were found in cross-sectional analyses for tobacco, alcohol, and marijuana use. A latent growth analysis showed that religiosity reduced the impact of life stress on initial level of substance use and on rate of growth in substance use over time. Implications for further research on religiosity and substance use are discussed.

Functions of non-suicidal self-injury in adolescents and young adults with Borderline Personality Disorder symptoms.

Rates of deliberate non-suicidal self-injury (NSSI) increase during adolescence and young adulthood, particularly in clinical samples, making these important developmental stages for understanding the functions of NSSI. Borderline Personality Disorder (BPD) symptoms also begin to emerge in adolescence, though little research has examined relationships between BPD symptoms and the functions of NSSI in youth, the primary goal of the present study. Adolescents and young adults recruited from an outpatient psychotherapy clinic (N=36) endorsed a range of NSSI functions on the Inventory of Statements about Self-Injury (Klonsky and Glenn, 2009). Participants engaged in NSSI to serve intrapersonal functions (e.g., regulate affect, punish oneself) more frequently than interpersonal functions (e.g., bond with peers, establish autonomy). As predicted, linear regression analyses indicated that BPD affective dysregulation symptoms were associated with the intrapersonal but not the interpersonal functions of NSSI. In contrast, BPD interpersonal dysfunction symptoms were differentially associated with the interpersonal rather than intrapersonal functions of NSSI. These preliminary data indicate that clusters of BPD symptoms show unique relationships with functions of NSSI in treatment-seeking adolescents and young adults, relationships that can be used to target specific functions of NSSI in treatment planning.
