A new publication from HALO Post-doc Dr. Michelle Guerrero and colleagues titled “Longitudinal relations between psychological distress and moderate-to-vigorous physical activity: A latent change score approach” was just published in Psychology of Sport & Exercise. This investigation was the first to document that changes in moderate- to vigorous-intensity physical activity and psychological distress are coupled temporally. This work came from part of Dr. Guerrero’s PhD training. Congratulations Michelle! Citation details and a summary of the paper are below.

Objectives. The effect of physical inactivity on mental health risk is well established; however, less is known about about how psychological distress might deter participation in physical activity. Guided by advancements in the treatment of longitudinal data, the aim of this study was to examine patterns and predictors of change in moderate-to-vigorous physical activity (MVPA) and psychological distress (e.g., feeling nervous, worthless). Design method. Australian adults (4944 females, Mage = 34.63 years ±5.34; 4322 males, Mage = 37.51 years ±6.14) provided baseline data as part of the Longitudinal Study of Australian Children (LSAC) and were followed for measurements every two years for 10 years. Results. Latent change score analyses revealed support for a reciprocal effects model, whereby change in MVPA and psychological distress occurred as a function of individuals’ prior levels of, and/or prior change in these variables. Conclusions. This investigation is the first to document that changes in MVPA and psychological distress are coupled temporally. Notably, we observed that individuals’ distress levels at a given time point predicted subsequent change on both MVPA and distress; a finding which provides novel and important insight into how adults’ activity levels and psychological distress fluctuate relative to one another.
