Longitudinal Relations Between Parenting Practices and Adolescent Suicidal Ideation in a High-Risk Clinical Sample: A Moderated Mediation Model.

Parenting behaviors are associated with adolescent suicidal ideation (SI), but few studies have examined this relation longitudinally or investigated underlying mechanisms. We investigated a moderated mediation model to evaluate perceived burdensomeness as a mediator in the longitudinal relation between parenting behavior (warmth and verbal hostility) and adolescent SI. We hypothesized that this association would be particularly strong among adolescents with greater functional impairment. The sample included 147 adolescents (Mage = 14.9, Age Range = 12-18 years, 76.2% female) and a primary caregiver (Mage = 43.5, Age Range = 27-60 years, 81.4% female) enrolled in a clinical trial. Caregivers completed measures of warmth and verbal hostility (PCPR) and adolescents completed measures of functional impairment (CDI-2), perceived burdensomeness (INQ), and SI (SIQ-JR) at baseline, 12 and 18 months. Two moderated mediation path analyses, one for each parenting behavior, were conducted. Age, sex, treatment condition, baseline and 12-month SI, baseline perceived burdensomeness, and the alternate baseline parenting behavior were included as covariates. Neither model yielded a significant direct effect between baseline parental verbal hostility or warmth and 18-month SI. However, lower warmth and higher verbal hostility were positively associated with 18-month SI indirectly through greater 12-month perceived burdensomeness among youth with relatively higher levels of functional impairment. Perceptions of burdensomeness are a mechanism by which low parental warmth and high parental verbal hostility contribute to SI, but only among youth with greater functional impairment. Interventions to address youth perceptions of burdensomeness may be beneficial, particularly for the most highly impaired youth.

Longitudinal associations between high school sleep characteristics and young adult health outcomes.

STUDY OBJECTIVES: Short sleep duration and evening chronotype are independently associated with negative health outcomes. However, it is unclear how adolescent sleep duration and chronotype are longitudinally associated with health outcomes during early adulthood. METHODS: Participants from the NEXT Generation Health Study (n = 2,783; 54.5% female) completed measures of sleep duration (scheduled day and unscheduled day) and chronotype in high school. Sleep duration, chronotype, general health, depressive symptoms, and psychosomatic symptoms were also assessed 4 years after high school. Latent variables estimated high school scheduled-day sleep duration, unscheduled-day sleep duration, and chronotype using the during high school measures. Two path analyses tested the prospective associations between high school sleep duration (separate models for scheduled and unscheduled days) and chronotype with 4 years after high school health outcomes as mediated by concurrent sleep duration and chronotype. RESULTS: In the scheduled-day model, longer high school sleep duration and later chronotype were associated with longer duration and later chronotype in early adulthood. Longer high school sleep duration was directly associated with fewer psychosomatic symptoms and indirectly associated with fewer depressive and psychosomatic symptoms through longer sleep duration in early adulthood. Later chronotype in high school was indirectly associated with poorer general health, greater depressive symptoms, and greater psychosomatic symptoms in early adulthood through later chronotype. CONCLUSIONS: Findings highlight the roles of scheduled-day sleep duration and evening chronotype in shaping health outcomes and suggest the importance of chronotype and optimal sleep habits among adolescents.

A prospective investigation of the relation between dysfunctional family communication and suicidal ideation severity in a clinical adolescent sample: A serial mediation model.

BACKGROUND: Extant research has documented a relation between the quality of family communication and adolescent suicidal ideation. However, few studies have examined this relation longitudinally or explored potential mechanisms of this effect. In the present study, unhealthy family communication was hypothesized to be associated with suicidal ideation severity over 18 months via a serial mediation pathway through emotion regulation difficulties and depressive symptom severity. METHODS: The sample consisted of 147 adolescents (Mage = 14.91, SD = 1.51, range = 12-18 years; 76.2% female, 85.5% White) enrolled in a randomized clinical trial. Family communication quality was assessed at baseline using the Family Assessment Device. Emotion regulation difficulties and depressive symptoms were assessed using the Difficulties in Emotion Regulation Scale and Children's Depression Inventory-2, respectively, at baseline, 6-, and 12-months. Suicidal ideation was assessed using the Suicidal Ideation Questionnaire-JR at baseline and 18-months. Path analysis was used to analyze temporal relations between constructs. RESULTS: After accounting for participant's age, sex, treatment condition, and baseline levels of variables of interest, analyses supported the indirect relation between baseline family communication and 18-month suicidal ideation severity through 6-month emotion regulation difficulties and 12-month depressive symptom severity. LIMITATIONS: Data were exclusively collected via self-report, and the sample was racially homogenous. CONCLUSIONS: Treatment aimed at improving family communication may help bolster emotion regulation abilities, lower depressive symptoms, and subsequently, suicide risk.

Three Dimensions of Sleep, Somatic Symptoms, and Marijuana Use in U.S. High School Students.

PURPOSE: This study aimed to investigate potential bidirectional relations between key sleep characteristics and somatic symptoms with past 30-day marijuana use in high school students. METHODS: Participants from the NEXT Generation Health Study (n = 2,770) reported on 10th and 11th grade (W1 and W2) sleep characteristics and somatic symptoms and 12th grade (W3) past 30-day marijuana. Multivariate logistic regressions and path analyses were conducted. RESULTS: Sleep duration was not associated with marijuana use. However, later W1 chronotype, greater W1 social jetlag, W1 trouble falling asleep, W1 trouble staying asleep, and W1 somatic symptoms were associated with increased odds of W3 past 30-day marijuana use. Path models indicated direct associations between W1 chronotype and W3 past 30-day marijuana use, and W1 social jetlag and W3 past 30-day marijuana use. CONCLUSIONS: Later sleep timing was longitudinally associated with past 30-day marijuana use. Improved understanding of sleep health, specifically chronotype and social jetlag as risk factors for marijuana use is warranted, which may inform additional screening targets and interventions that address these associated domains.

Resilience Factors in the Association Between Depressive Symptoms and Suicidality.

PURPOSE: To investigate whether life satisfaction and optimism might reduce the risk of suicidal thoughts and behaviors among adolescents with depressive symptoms. METHODS: Participants were 1,904 youth from the NEXT Generation Health Study, a national sample of U.S. adolescents, followed over 7 years from 2009/2010 to 2015/2016. Longitudinal latent profile analysis and logistic regressions were conducted. RESULTS: We identified three subgroups of adolescents with different patterns of depressive symptoms across the first six waves: "Low" (40%), "Mild" (42%), and "Moderate to Severe" (18%). The Moderate to Severe (OR = 14.47, 95% CI [6.61, 31.66]) and Mild (OR = 3.90, 95% CI [2.22, 6.86]) depression profiles had significantly higher odds of developing suicidality than the Low depression profile. Both life satisfaction and optimism moderated the association between depressive symptom profile and suicidality. The difference in suicidality risk between the Mild and Low depression profiles was significantly attenuated at high versus low levels of life satisfaction, with a difference of -.08, 95% CI [-.14, -.03]. In addition, the difference in suicidality risk between the Moderate to Severe and Low depression profiles was attenuated at high versus low levels of optimism, with a difference of -.11, 95% CI [-.21, -.01]. CONCLUSIONS: For adolescents transitioning to young adulthood, resilience factors such as life satisfaction and optimism may buffer against suicidality risk in the face of mild or moderate to severe depressive symptoms.
