Five versions of the Interpersonal Needs Questionnaire (INQ), a self-report measure of perceived burdensomeness and thwarted belongingness, have been used in recent studies (including 10-, 12-, 15-, 18-, and 25-items). Findings regarding the associations between perceived burdensomeness, thwarted belongingness, and suicidal ideation using different versions have been mixed, potentially due to differences in measurement scales. This study evaluated factor structure, internal consistency, and concurrent predictive validity of these five versions in three samples. Samples 1 and 2 were comprised of 449 and 218 undergraduates, respectively; Sample 3 included 114 adolescent psychiatric inpatients. All versions demonstrated acceptable internal consistency. The 10-item version and 15-item version demonstrated the best, most consistent model fit in confirmatory factor analyses. Both perceived burdensomeness and thwarted belongingness consistently predicted concurrent suicidal ideation on the 10-item INQ only. Future research should consider using the 15-item or 10-item versions.

ObjectiveThe Genes for Treatment study is an international, multisite collaboration exploring the role of genetic, demographic, and clinical predictors in response to cognitive-behavioral therapy (CBT) in pediatric anxiety disorders. The current article, the first from the study, examined demographic and clinical predictors of response to CBT. We hypothesized that the child’s gender, type of anxiety disorder, initial severity and comorbidity, and parents’ psychopathology would significantly predict outcome.MethodA sample of 1,519 children 5 to 18 years of age with a primary anxiety diagnosis received CBT across 11 sites. Outcome was defined as response (change in diagnostic severity) and remission (absence of the primary diagnosis) at each time point (posttreatment, 3-, 6-, and/or 12-month follow-up) and analyzed using linear and logistic mixed models. Separate analyses were conducted using data from posttreatment and follow-up assessments to explore the relative importance of predictors at these time points.ResultsIndividuals with social anxiety disorder (SoAD) had significantly poorer outcomes (poorer response and lower rates of remission) than those with generalized anxiety disorder (GAD). Although individuals with specific phobia (SP) also had poorer outcomes than those with GAD at posttreatment, these differences were not maintained at follow-up. Both comorbid mood and externalizing disorders significantly predicted poorer outcomes at posttreatment and follow-up, whereas self-reported parental psychopathology had little effect on posttreatment outcomes but significantly predicted response (although not remission) at follow-up.ConclusionSoAD, nonanxiety comorbidity, and parental psychopathology were associated with poorer outcomes after CBT. The results highlight the need for enhanced treatments for children at risk for poorer outcomes.

Treatment specificity and long-term recovery mediation of peer-involvement group cognitive behavioral therapy (GCBT) and parent-involvement CBT (PCBT) were investigated for youth anxiety disorders. Two hundred forty youths with primary anxiety diagnoses participated in a randomized controlled efficacy trial. Youth anxiety and peer variables/mediators (positive peer–youth relationships; social skills) and parent variables/mediators (psychological control; negative parent–youth relationships) were assessed. At posttreatment and 12-month follow-up, positive peer-youth relationships were significantly higher in GCBT than PCBT (specificity) according to youth and parent ratings. At posttreatment but not follow-up, parental psychological control was significantly lower in PCBT than GCBT (specificity) and findings varied by informants. Parental psychological control and positive peer–youth relationships were putative mediators. The two CBTs produced similar anxiety reductions through different mechanisms. CBT targets show specificity and mediation, providing insight into specific mechanisms through which GCBT and PCBT bring about anxiety reduction and guidance for streamlining these CBTs in practice.
