IL-6 predicts non-suicidal self-injury over 3 months in high-risk adolescents.

BACKGROUND: Suicide is the second leading cause of death in 12- to 17-year-old adolescents in the USA. Research on biological mechanisms contributing to self-harm risk that could be targeted in treatment could help to prevent suicide and self-harm episodes. AIMS: We aimed to evaluate whether markers of inflammation, interleukin-6 (IL-6) and C-reactive protein (CRP), predict self-harm over 3 months within a sample selected for elevated suicide/self-harm risk at project entry. METHOD: Fifty-one adolescents aged 12-19 years selected for elevated suicide/self-harm risk completed three clinical interviews about suicide attempts and non-suicidal self-injury, 3 months apart. At baseline and 3 months, youth also provided blood samples, from which we assayed levels of IL-6 and CRP. RESULTS: Using generalised mixed models, we found that greater levels of IL-6 predicted more self-harm episodes (odds ratio [OR] = 3.3, 95% CI: 1.1, 10.0) and specifically, non-suicidal self-injury (OR = 3.5, 95% CI: 1.1, 11.2), over 3 months. CONCLUSIONS: The study findings increase our understanding of whether and how inflammation may be implicated in risk of self-harm. IL-6 may be a viable biological marker of short-term risk for self-harm.

Future Directions for Optimizing Clinical Science & Safety: Ecological Momentary Assessments in Suicide/Self-Harm Research.

OBJECTIVE: Mobile technology has facilitated rapid growth in the use of intensive longitudinal methods (ILM), such as ecological momentary assessments (EMA), that help identify proximal indicators of risk in real-time and real-world settings. To realize the potential of ILM for advancing knowledge regarding suicidal and self-injurious thoughts and behaviors (SITB), this article aims to provide a systematic review of safety protocols in published ILM studies of youth SITB, highlight considerations for maximizing safety, and offer an agenda for future research. METHOD: We conducted a systematic review of risk management strategies in published studies applying ILM to assess SITB in youth. RESULTS: The review indicated diverse safety strategies, with near-universal use of preventive strategies before beginning ILM surveys. Strategies for participant protection during the survey period included automated protective messages to seek support when elevated risk was detected; and staff-led strategies, some of which included active outreach to parents/caregivers when youth responses suggested elevated risk. Studies assessing suicidality all provided staff-led follow-up. There was minimal information on youth reactivity to intensive longitudinal assessments of SITB. Available evidence did not suggest increased suicidal ideation, suicide attempts, self-injurious behavior, or deaths with ILM. CONCLUSIONS: Based on the review, we propose a research agenda to inform safety procedures in ILM research and a model for managing risk in future ILM studies of youth SITB. This model begins with a needs assessment and proposes a "goodness of fit" approach for matching safety procedures to the specific needs of each ILM study.

Sleep in youth with repeated self-harm and high suicidality: Does sleep predict self-harm risk?

OBJECTIVE: To elucidate processes contributing to continuing self-harm in youth at very high risk for suicide, focusing on sleep disturbance, a putative warning sign of imminent suicide risk. METHOD: 101 youth (ages 12-18) selected for high risk of suicide/suicide attempts based on suicidal episodes plus repeated self-harm (suicide attempts and/or nonsuicidal self-injury [NSSI]). Youth were assessed at baseline, 6-, and 12-month follow-ups on measures of self-harm, suicidality, sleep, and depression. RESULTS: Youth showed high rates of baseline sleep disturbance: 81.2% scored in the clinical range on the Pittsburgh Sleep Quality Index (PSQI); 81.2% reported an evening (night owl) circadian preference. PSQI score was associated with elevated levels of self-harm (suicide attempts and NSSI) contemporaneously and predicted future self-harm within 30 days. Rates of self-harm were high during follow-up: 45.0% and 33.7% at 6 and 12 months, respectively. CONCLUSIONS: Results underscore the need to move beyond an acute treatment model to prevent recurrent and potentially deadly self-harm, the importance of clarifying mechanisms contributing to elevated suicide/self-harm risk, and the potential promise of engaging sleep as a therapeutic target for optimizing treatment and elucidating mechanistic processes.

Adolescent Suicide Attempt Prevention: Predictors of Response to a Cognitive-Behavioral Family and Youth Centered Intervention.

OBJECTIVE: Suicide is a leading cause of adolescent death. Recent data support the efficacy of cognitive-behavioral treatments with strong family components for reducing suicide risk; however, not all youth benefit from current interventions. Identifying predictors of treatment response can inform treatment selection and optimize benefits. METHOD: This study examines predictors of response to a DBT-informed cognitive-behavioral family treatment (SAFETY), among 50 youth with recent suicide attempts/self-harm. Youth and parents were assessed at baseline and post-treatment. RESULTS: Results indicated medium-to-large effect sizes for SAFETY on youth suicidal behavior (SB; defined as suicide attempts, aborted attempts, and planning), depression, hopelessness, social adjustment, and parental depression. Classification tree analysis, with a correct classification rate of 93.3%, and follow-up logistic analyses indicated that 35% of youths reporting active SB at baseline reported active SB at post-treatment, whereas post-treatment SB was rare among youths whose active suicidality had resolved by the baseline assessment (5%). Among youths reporting baseline SB, those endorsing sleep problems were more likely to report post-treatment SB (53%) versus those without sleep problems (0%). CONCLUSIONS: These findings highlight the potential value of personalized treatment approaches based on pretreatment characteristics and the significance of baseline SB and sleep problems for predicting treatment response.

Cognitive-Behavioral Family Treatment for Suicide Attempt Prevention: A Randomized Controlled Trial.

OBJECTIVE: Suicide is a leading cause of death. New data indicate alarming increases in suicide death rates, yet no treatments with replicated efficacy or effectiveness exist for youths with self-harm presentations, a high-risk group for both fatal and nonfatal suicide attempts. We addressed this gap by evaluating Safe Alternatives for Teens and Youths (SAFETY), a cognitive-behavioral, dialectical behavior therapy-informed family treatment designed to promote safety. METHOD: Randomized controlled trial for adolescents (12-18 years of age) with recent (past 3 months) suicide attempts or other self-harm. Youth were randomized either to SAFETY or to treatment as usual enhanced by parent education and support accessing community treatment (E-TAU). Outcomes were evaluated at baseline, 3 months, or end of treatment period, and were followed up through 6 to 12 months. The primary outcome was youth-reported incident suicide attempts through the 3-month follow-up. RESULTS: Survival analyses indicated a significantly higher probability of survival without a suicide attempt by the 3-month follow-up point among SAFETY youths (cumulative estimated probability of survival without suicide attempt = 1.00, standard error = 0), compared to E-TAU youths (cumulative estimated probability of survival without suicide attempt = 0.67, standard error = 0.14; z = 2.45, p = .02, number needed to treat = 3) and for the overall survival curves (Wilcoxon χ21 = 5.81, p = .02). Sensitivity analyses using parent report when youth report was unavailable and conservative assumptions regarding missing data yielded similar results for 3-month outcomes. CONCLUSION: Results support the efficacy of SAFETY for preventing suicide attempts in adolescents presenting with recent self-harm. This is the second randomized trial to demonstrate that treatment including cognitive-behavioral and family components can provide some protection from suicide attempt risk in these high-risk youths.

Experimentally induced distraction impacts cognitive but not emotional processes in think-aloud cognitive assessment.

Studies have examined the impact of distraction on basic task performance (e.g., working memory, motor responses), yet research is lacking regarding its impact in the domain of think-aloud cognitive assessment, where the threat to assessment validity is high. The Articulated Thoughts in Simulated Situations think-aloud cognitive assessment paradigm was employed to address this issue. Participants listened to scenarios under three conditions (i.e., while answering trivia questions, playing a visual puzzle game, or with no experimental distractor). Their articulated thoughts were then content-analyzed both by the Linguistic Inquiry and Word Count (LIWC) program and by content analysis of emotion and cognitive processes conducted by trained coders. Distraction did not impact indices of emotion but did affect cognitive processes. Specifically, with the LIWC system, the trivia questions distraction condition resulted in significantly higher proportions of insight and causal words, and higher frequencies of non-fluencies (e.g., "uh" or "umm") and filler words (e.g., "like" or "you know"). Coder-rated content analysis found more disengagement and more misunderstanding particularly in the trivia questions distraction condition. A better understanding of how distraction disrupts the amount and type of cognitive engagement holds important implications for future studies employing cognitive assessment methods.
