Depressed Adolescents Treated with Exercise (DATE): A pilot randomized controlled trial to test feasibility and establish preliminary effect sizes.

ABSTRACT: The Depressed Adolescents Treated with Exercise (DATE) study evaluated a standardized aerobic exercise protocol to treat nonmedicated adolescents that met DSM-IV-TR criteria for major depressive disorder. From an initial screen of 90 individuals, 30 adolescents aged 12-18 years were randomized to either vigorous exercise (EXER) (>12 kg/kcal/week [KKW]) or a control stretching (STRETCH) activity (< 4 KKW) for 12 weeks. The primary outcome measure was the blinded clinician rating of the Children's Depression Rating Scale - Revised (CDRS-R) to assess depression severity and Actical (KKW) accelerometry 24hr/7days a week to assess energy expenditure and adherence. Follow-up evaluations occurred at weeks 26 and 52. The EXER group averaged 77% adherence and the STRETCH group 81% for meeting weekly target goals for the 12 week intervention based on weekly sessions completed and meeting KKW requirements. There was a significant increase in overall weekly KKW expenditures (p < .001) for both groups with the EXER group doubling the STRETCH group in weekly energy expenditure. Depressive symptoms were significantly reduced from baseline for both groups with the EXER group improving more rapidly than STRETCH after six weeks (p < .016) and nine weeks (p < .001). Both groups continued to improve such that there were no group differences after 12 weeks (p = .07). By week 12, the exercise group had a 100% response rate (86% remission), whereas the stretch group response rate was 67% (50% remission) (p = .02). Both groups had improvements in multiple areas of psychosocial functioning related to school and relationships with parents and peers. Anthropometry reflected decreased waist, hip and thigh measurements (p = .02), more so for females than males (p = .05), but there were no weight changes for either gender. The EXER group sustained 100% remission at week 26 and 52. The STRETCH group had 80% response and 70% remission rates at week 26 and by week 52 only one had not fully responded. The study provides support for the use of exercise as a non-medication intervention for adolescents with major depressive disorders when good adherence and energy expenditure (KKW) are achieved.

Project description:Adolescence is a neuroplastic period for self-processing and emotion regulation transformations, that if derailed, are linked to persistent depression. Neural mechanisms of adolescent self-processing and emotion regulation ought to be targeted via new treatments, given moderate effectiveness of current interventions. Thus, we implemented a novel neurofeedback protocol in adolescents to test the engagement of circuits sub-serving self-processing and emotion regulation. METHODS:Depressed (n?=?34) and healthy (n?=?19) adolescents underwent neurofeedback training using a novel task. They saw their happy face as a cue to recall positive memories and increased displayed amygdala and hippocampus activity. The control condition was counting-backwards while viewing another happy face. A self vs. other face recognition task was administered before and after neurofeedback training. RESULTS:Adolescents showed higher frontotemporal activity during neurofeedback and higher amygdala and hippocampus and hippocampi activity in time series and region of interest analyses respectively. Before neurofeedback there was higher saliency network engagement for self-face recognition, but that network engagement was lower after neurofeedback. Depressed youth exhibited higher fusiform, inferior parietal lobule and cuneus activity during neurofeedback, but controls appeared to increase amygdala and hippocampus activity faster compared to depressed adolescents. CONCLUSIONS:Neurofeedback recruited frontotemporal cortices that support social cognition and emotion regulation. Amygdala and hippocampus engagement via neurofeedback appears to change limbic-frontotemporal networks during self-face recognition. A placebo group or condition and contrasting amygdala and hippocampus, hippocampi or right amygdala versus frontal loci of neurofeedback, e.g. dorsal anterior cingulate cortex, with longer duration of neurofeedback training will elucidate dosage and loci of neurofeedback in adolescents.

Project description:BackgroundDepression in adolescents is a large and growing problem; however, access to effective mental health care continues to be a challenge. Digitally based interventions may serve to bridge this access gap for adolescents in need of care. Digital interventions that deliver components of cognitive behavioral therapy (CBT) have been shown to reduce symptoms of depression, and virtual reality (VR) may be a promising adjunctive component. However, research on these types of treatments in adolescents and young adults is limited.ObjectiveThis study aims to evaluate the feasibility, acceptability, and preliminary efficacy of Spark (v1.0), a 5-week, self-guided, CBT-based digital program using a mobile app and VR experiences to target symptoms of depression in adolescents.MethodsA single-arm, open-label study of the Spark program was conducted with a community sample of 30 adolescents and young adults aged 12 to 21 years with self-reported moderate to severe depression symptoms. Participants completed a weekly depression assessment (Patient Health Questionnaire-8) in the app during the 5-week intervention period as well as web-based baseline, postintervention, and 1-month follow-up self-report assessments. The participants also completed a qualitative postintervention interview. For participants aged <18 years, caregivers completed assessments at baseline and postintervention time points. Feasibility outcomes included recruitment rate (the proportion of participants who enrolled in the study divided by the total number of participants screened for eligibility) and retention rate (the proportion of participants who completed postintervention assessments divided by the total number of participants who received the intervention). Acceptability outcomes included engagement with the program and quantitative and qualitative feedback about the program. Preliminary efficacy was evaluated based on the Patient Health Questionnaire-8.ResultsThe study recruitment (31/66, 47%) and retention (29/30, 97%) rates were high. Participants provided higher ratings for the ease of use of the Spark program (8.76 out of 10) and their enjoyment of both the mobile app (7.00 out of 10) and VR components (7.48 out of 10) of the program, whereas they provided lower ratings for the program's ability to improve mood (4.38 out of 10) or fit into their daily routines (5.69 out of 10). We observed a clinically and statistically significant reduction in depression scores at postintervention (mean difference 5.36; P<.001) and 1-month follow-up (mean difference 6.44; P<.001) time points.ConclusionsThe Spark program was found to be a feasible and acceptable way to deliver a self-guided CBT-focused intervention to adolescents and young adults with symptoms of depression. Preliminary data also indicated that the Spark program reduced the symptoms of depression in adolescents and young adults. Future studies should evaluate the efficacy of this intervention in an adequately powered randomized controlled trial.Trial registrationClinicalTrials.gov NCT04165681; https://classic.clinicaltrials.gov/ct2/show/NCT04165681.
