Posttraumatic Growth in Youth, Young Adults, and Caregivers Who Experienced Solid Organ Transplant.

OBJECTIVE: To explore posttraumatic growth (PTG) in pediatric patients who have undergone solid organ transplant (SOT) and their caregivers, and to examine potential correlates of PTG. METHOD: Youth and young adults with a history of SOT (heart, kidney, liver) at least 1 month prior to participation and caregivers completed measures of PTG, demographic, and medical factors. In total, 59 youth (M = 12.68 years, SD = 1.91), 21 young adults (M = 19.37, SD = 0.82), and 95 caregivers (M = 37.95 years, SD = 9.37) participated. RESULTS: Overall, 67% of youth, 76% of young adults, and 89% of caregivers reported PTG within the medium to very high range. Appreciation of Life was the highest PTG subscale across all groups. Youth and caregiver PTG scores were significantly positively correlated. Religious affiliation and religious coping were positively associated with PTG for caregivers, and the relationship yielded large effect sizes for young adults. Caregivers of children with kidney transplants endorsed lower PTG than other organ types and caregivers of children who had an acute medical condition endorsed greater PTG than caregivers of children who had chronic illness. CONCLUSION: Findings suggest the pediatric SOT experience can yield positive changes such as a greater appreciation of life. Although small sample sizes may have led to reduced power for detecting significant findings for some analyses, results suggest religious, medical, and parent-child relationship factors are likely related to PTG in pediatric SOT and warrant future investigation.

Measuring Thwarted Belongingness and Perceived Burdensomeness in Clinically Depressed and Suicidal Youth: Refinement and Reduction of the Interpersonal Needs Questionnaire.

OBJECTIVE: The Interpersonal-Psychological Theory of Suicide (IPTS) posits two constructs (thwarted belongingness (TB) and perceived burdensomeness (PB)) contribute to suicide ideation. These constructs are typically measured by the Interpersonal Needs Questionnaire (INQ); however, available INQ versions have demonstrated poor psychometric properties with youth. This study examined the INQ using Item Response Theory (IRT) to refine and reduce the scale for clinically depressed and suicidal youth. METHODS: Participants were 378 youth (Age M (SD) = 14.78 (1.41), 82.54% female) who completed the INQ. The INQ contains 25 items across two subscales (i.e., TB and PB) rated on a 7-point Likert-type scale. Rating scale performance, dimensionality, model fit, and instrument-level statistics were examined using IRT methodology. Post hoc analyses were performed to further reduce the scale. RESULTS: The INQ was reduced from 25 to 10 items (five per subscale), and response options were refined to four choices. Correlations between original and IRT-refined items were large (r = .97 for PB; r = .98 for TB). Additional item-level (e.g., fit, difficulty) and instrument-level (e.g., dimensionality) characteristics were examined. CONCLUSIONS: The newly refined INQ resulted in improved scale reliability and validity. The psychometrically improved INQ can assist clinicians and researchers identify adolescents at risk of experiencing suicide ideation.

Double trouble: Nonsuicidal self-injury and its relationship to suicidal ideation and number of past suicide attempts in clinical adolescents.

BACKGROUND: Death by suicide is one of the leading causes of mortality among adolescents, and nonsuicidal self-injury (NSSI) is one of the strongest predictors of suicide attempts (SAs). The underlying bases for this relationship are unknown. We derived two hypotheses from the Interpersonal Psychological Theory of Suicide (IPTS): unmet interpersonal needs would explain NSSI's association with suicidal ideation (SI) and increased capability for suicide would explain NSSI's relationship with SA. METHODS: Adolescents hospitalized on a psychiatric inpatient unit (N = 289) provided measures of current SI, number of past SAs, unmet interpersonal needs (perceived burdensomeness and thwarted belongingness), capability for suicide (fearlessness about death [FAD] and pain tolerance), depressive symptoms, and number of NSSI methods utilized. RESULTS: Depressive symptoms, but not unmet interpersonal needs, explained NSSI's association with SI. FAD and SI, but not depressive symptoms or pain tolerance, accounted for NSSI's relationship with SA. FAD was associated with SA, but it did not fully account for NSSI's relationship with SA. LIMITATIONS: This study utilized a cross-sectional design and retrospective, self-report measures. CONCLUSIONS: Our study provides partial support for the role of the IPTS variables in NSSI's relationship with SA in adolescents. The finding that depressive symptoms and not unmet interpersonal needs explained NSSI's relationship with SI contradicts the IPTS. However, in those with SI, FAD was linearly associated with SA, which is consistent with the IPTS. Future studies are needed to clarify the persistent basis for NSSI's relationship with SA beyond FAD and SI.
