Abstract
Introduction: Physical activity (PA) is recommended to improve physical health in people with psychosis, however, most of them are inactive. Objectives: The objectives of the study were to assess the feasibility of a four-week brief theory-based intervention to improve PA in men with psychosis and obesity. Methods: A Quasi- experimental pre- post design evaluating the feasibility, the participation, and the intervention drop-out rate was conducted. PA, sedentary time, motivational processes of change, and anthropometric measures were evaluated. Results: A total of 38 men with psychotic disorders were approached and 32% participated (n = 12). Among these 12 participants, 75% had schizophrenia, their mean age was 33.2 ± 10.2, and mean Body Mass Index: 35.8 ± 7.7 kg/m2. Besides, all 12 participants (100%) completed the intervention. Participants reported a high satisfaction rate in the intervention. Following the intervention, PA level was increased with a moderate effect size. Similarly, an increase in behavioral processes of change was observed with a moderate effect size. Discussion and conclusion: Hence, the brief theory-based intervention was feasible and could probably improve the PA level in men with psychosis and obesity.

In a physical activity context, brief intervention can be defined as any “intervention involving verbal advice, encouragement, negotiation or discussion with the overall aim of increasing physical activity delivered in a primary care setting by a health or exercise professional, with or without written support or follow-up” (National Institute for Health and Care Excellence, 2013, p. 7)
It was hypothesized that the study would be feasible in terms of participation rate, and that it would result in an improvement in total physical activity and a reduction in sedentary time
Summary
L’activité physique (AP) est recommandée pour améliorer la santé physique de personnes ayant un trouble psychotique, toutefois la plupart d’entre elles sont physiquement inactives. The transtheoretical model is a composite model of behaviour change with three core components being decisional balance (perceived advantages/disadvantages related to the decision to change behaviour), self-efficacy (individuals’ judgment of their abilities to organize and execute courses of action required to attain designated types of performance) and the ten processes of change (five experiential and five behavioural strategies used by individuals to modify their behaviour) (Prochaska et al, 2008) Several studies showed this model to improve physical activity in different populations (Gourlan et al.; Romain et al, 2018)
