Prospective Relations between Life Stress, Emotional Clarity, and Suicidal Ideation in an Adolescent Clinical Sample.

Journal of Clinical Oncology

Although life stress has been linked to adolescent suicidal ideation, most past research has been cross-sectional, and potential processes characterizing this relation remain unclear. One possibility may be a lack of emotional clarity. Informed by stress generation, the current study examined prospective relations between episodic life stress, lack of emotional clarity, and suicidal ideation in an adolescent clinical sample.

The sample consisted of 180 youths (Mage = 14.89; SD = 1.35; 71.7% female; 78.9% White; 43.0% sexual minority) recruited from a psychiatric inpatient facility. Suicidal ideation severity was assessed at baseline and 18-month follow-up. Lack of emotional clarity and life stress were assessed at baseline, as well as 6-, and 12-month follow-ups. Two random-intercepts cross-lagged panel models were created to estimate within-person relations for variables of interest.

At the within-person level, lack of emotional clarity at baseline predicted greater 6-month impact of interpersonal dependent stressors (b = 0.29, p = .012, 95% CI [0.07, 0.52]), which subsequently predicted a greater 12-month lack of emotional clarity (b = 0.41, p = .005, 95% CI [0.12, 0.70]). Next, a 12-month lack of emotional clarity but not interpersonal dependent stress, predicted greater 18-month suicidal ideation (b = 0.81, p = .006, 95% CI [0.23, 1.30]; R2 = .24, p < .001). No significant relations were found for the lack of emotional clarity and independent stress.

Results support the stress generation hypothesis and suggest that future research should be conducted evaluating whether bolstering youth's understanding of their emotional experiences may reduce subsequent suicidal ideation.

Enhanced Skills Training in Affective and Interpersonal Regulation versus Treatment as Usual for ICD-11 Complex PTSD: A Pilot Randomised Controlled Trial (The RESTORE Trial).

Psychotherapy and Psychosomatics

Complex PTSD (CPTSD) is a relatively new condition in ICD-11. This pilot randomised controlled trial aimed to compare a four-module intervention developed to target all symptoms of ICD-11 CPTSD, namely Enhanced Skills in Affective and Interpersonal Regulation (ESTAIR) with treatment as usual (TAU). The purpose of the study was to assess feasibility, safety, acceptability, and preliminary outcomes at the end of treatment and 3-month follow-up.

A total of N = 56 eligible veterans with CPTSD were randomised to either ESTAIR (n = 28) or TAU (n = 28). Linear mixed models were conducted to assess CPTSD severity, the primary outcome, as measured by the International Trauma Questionnaire (ITQ).

Treatment dropout in ESTAIR and TAU was low and equivalent (18% vs. 11%; χ2 (1) = 1.19, p = 0.275), and study retention was high, supporting the feasibility of the study. No serious adverse effects and very few adverse effects occurred, none of which were deemed related to the study. ESTAIR provided significantly greater reduction in CPTSD severity across time for ITQ PTSD (p &lt; 0.001) and DSO (p &lt; 0.001) symptoms. CPTSD pre-to-post effect sizes for ESTAIR were large (PTSD d = 1.78; DSO d = 2.00). Remission of probable CPTSD diagnosis at post-treatment was substantially greater in ESTAIR compared to TAU with only 13.6% versus 84% (p &lt; 0.001) retaining the diagnosis.

A trial of ESTAIR versus TAU for the treatment of ICD-11 CPTSD indicates the potential efficacy of ESTAIR as well as its feasibility, safety, and acceptability.

Efficacy of an Internet- and Mobile-Based Intervention for Subclinical Anxiety and Depression (ICare Prevent) with Two Guidance Formats: Results from a Three-Armed Randomized Controlled Trial.

Psychotherapy and Psychosomatics

Limited research exists on intervention efficacy for comorbid subclinical anxiety and depressive disorders, despite their common co-occurrence. Internet- and mobile-based interventions (IMIs) are promising to reach individuals facing subclinical symptoms.

This study aimed to evaluate the efficacy of a transdiagnostic and self-tailored IMI in reducing subclinical anxiety and depressive symptom severity with either individualized (IG-IMI) or automated (AG-IMI) guidance compared to a waitlist control group with care-as-usual access (WLC).

Participants included 566 adults with subclinical anxiety (GAD-7 ≥ 5) and/or depressive (CES-D ≥16) symptoms, who did not meet criteria for a full-syndrome depressive or anxiety disorder. In a three-arm randomized clinical trial, participants were randomized to a cognitive behavioral 7-session IMI plus booster session with IG-IMI (n = 186) or AG-IMI (n = 189) or WLC (n = 191). Primary outcomes included observer-rated anxiety (HAM-A) and depressive (QIDS) symptom severity 8 weeks after randomization assessed by blinded raters via telephone. Follow-up outcomes at 6 and 12 months are reported.

Symptom severity was significantly lower with small to medium effects in IG-IMI (anxiety: d = 0.45, depression: d = 0.43) and AG-IMI (anxiety: d = 0.31, depression: d = 0.32) compared to WLC. No significant differences emerged between guidance formats in primary outcomes. There was a significant effect in HAM-A after 6 months favoring AG-IMI. On average, participants completed 85.38% of IG-IMI and 77.38% of AG-IMI.

A transdiagnostic, self-tailored IMI can reduce subclinical anxiety and depressive symptom severity, but 12-month long-term effects were absent. Automated guidance holds promise for enhancing the scalability of IMIs in broad prevention initiatives.

Follow-up and Mediation Outcomes of a Movement-Based Mental Health Promotion Intervention for Refugee Children in Uganda.

Journal of Clinical Oncology

There is limited evidence for the effectiveness of mental health promotion interventions in low- and middle-income settings, especially for longer-term benefits. This study evaluates the 5-month follow-up outcomes of a movement-based mental health promotion intervention (TeamUp) for refugee children in Northern Uganda (West Nile) and further investigates what explains longer-term benefits.

This quasi-experimental study was conducted in four primary schools, randomly allocated to an experimental or a control condition. Enrolled in the study were 549 children ages 10-15 years (n = 265 TeamUp; n = 284 control group). Primary outcomes were psychosocial well-being (Stirling Children's Wellbeing Scale), attitude toward school, and satisfaction with friendships (Multidimensional Students Life Satisfaction Scale [Friends and School subscales]). Mediators included social connectedness and sense of agency.

At 5 months postintervention, 467 (85.1%) children were retained. Intent-to-treat analyses demonstrated sustained benefits for TeamUp for well-being (estimated mean difference -1.88, 95% CI -3.14 to -0.66, p = .003, effect size Cohen's d = 0.25) and friendships (-1.52, 95% CI -2.55 to -0.48, p = .005, d = 0.25). There were no significant between-group differences for attitude toward school. Secondary benefits were shown for traumatic stress (2.18, 95% CI 0.45 to 3.91, p = .014, d = 0.21), quality of life (-1.29, 95% CI -2.31 to -0.30, p = .014, d = 0.21), bullying (0.53, 95% CI 0.08 to 0.97, p = .020, d = 0.20), and depression symptoms (1.31, 95% CI 0.09 to 2.52, p = .035, d = 0.18). Increased sense of connectedness mediates the effect of TeamUp on improving well-being (indirect effect = 0.30, SE = 0.13, p = .001), explaining 15% of variance.

This study shows sustained benefits of a mental health promotion intervention 5 months postintervention. Prolonged benefits are explained by an increase in social connectedness.

Contribution of basal ganglia activity to REM sleep disorder in Parkinson's disease.

Neurology, Neurosurgery and Psychiatry

Rapid eye movement (REM) sleep behaviour disorder (RBD) is one of the most common sleep problems and represents a key prodromal marker in Parkinson's disease (PD). It remains unclear whether and how basal ganglia nuclei, structures that are directly involved in the pathology of PD, are implicated in the occurrence of RBD.

Here, in parallel with whole-night video polysomnography, we recorded local field potentials from two major basal ganglia structures, the globus pallidus internus and subthalamic nucleus, in two cohorts of patients with PD who had varied severity of RBD. Basal ganglia oscillatory patterns during RBD and REM sleep without atonia were analysed and compared with another age-matched cohort of patients with dystonia that served as controls.

We found that beta power in both basal ganglia nuclei was specifically elevated during REM sleep without atonia in patients with PD, but not in dystonia. Basal ganglia beta power during REM sleep positively correlated with the extent of atonia loss, with beta elevation preceding the activation of chin electromyogram activities by ~200 ms. The connectivity between basal ganglia beta power and chin muscular activities during REM sleep was significantly correlated with the clinical severity of RBD in PD.

These findings support that basal ganglia activities are associated with if not directly contribute to the occurrence of RBD in PD. Our study expands the understanding of the role basal ganglia played in RBD and may foster improved therapies for RBD by interrupting the basal ganglia-muscular communication during REM sleep in PD.

Cognitive and interpersonal moderators of two evidence-based depression prevention programs.

Journal of Consulting and Clinical

To test potential cognitive and interpersonal moderators of two evidence-based youth depression prevention programs.

Two hundred four adolescents (Mage = 14.62 years, SD = 1.65; 56% female; 71% White, 11% Black, 11% multiracial, 5% Asian, 2% other races, 18% Hispanic/Latinx) were randomized to either a cognitive-behavioral (Coping With Stress [CWS]) or interpersonal (Interpersonal Psychotherapy-Adolescent Skills Training [IPT-AST]) prevention program. Potential moderators, selected based on theory and research, included rumination, negative cognitive style, dysfunctional attitudes, hopelessness, parent-adolescent conflict, negative interactions with parents and friends, and social support from parents and friends. Depression symptoms were assessed repeatedly through 18 months postintervention.

After adjusting for multiple comparisons, rumination (B = -2.02, SE = .61, p = .001, d = .47), hopelessness (B = -2.03, SE = .72, p = .005, d = .41), and conflict with father (B = 1.68, SE = .74, p = .02, d = .32) moderated intervention effects on change in depression symptoms from postintervention through 18-month follow-up. For example, at high levels of conflict with father, youth in IPT-AST reported a significant decrease in symptoms during follow-up, whereas youth in CWS reported a nonsignificant change in symptoms. At low levels of conflict with father, youth in IPT-AST reported a significant increase in symptoms during follow-up, whereas youth in CWS reported a nonsignificant change in symptoms.

These exploratory secondary analyses of Personalized Depression Prevention study data highlight specific cognitive and interpersonal risk factors that could be considered when determining which prevention program may be most effective for a given adolescent.
