Predicting depressive symptoms through social support: a machine learning approach in military populations
Published 2025-12-01“…However, limited research has explored how different types of support, emotional, informational, and instrumental, from multiple sources uniquely predict mental health outcomes. Subgroup differences based on gender, socioeconomic status (SES), and future orientation also remain under-investigated.Objective: This study used machine learning (ML) to examine the predictive effects of perceived social support on depressive symptoms among military cadets, while identifying key subgroup variations to inform tailored mental health strategies.Method: Data were drawn from the Career Development Study of Military Personnel across four waves: SES at Wave 1 (W1), personal future orientation at Wave 2 (W2), perceived military social support at Wave 3 (W3), and depressive symptoms at Wave 4 (W4) (N = 2,978). …”

School-level variation in children’s moderate to vigorous intensity physical activity before and after COVID-19: a multilevel model analysis
Published 2024-10-01“…Post lockdown, we collected accelerometer, individual and school data from 393 children in 23 of the same schools and 436 children in 27 of the same schools in 2021 (Wave 1) and 2022 (Wave 2), respectively. Methods Sources of variation (between-school, between-pupil and within-pupil) in child weekday moderate to vigorous physical activity at each wave were modelled using linear mixed-effects models with school-level wave random coefficients. …”
