Developing a Sound Body: Open Trial Results of a Group Healthy Lifestyle Intervention for Young Adults with Psychosis

Effectiveness of Walking Exercise in Improving Physical Fitness and Depression in Patients With Schizophrenia

Patients with schizophrenia often lack physical activity, which, together with physical complications, can lower their expected lifespan. Exercise strengthens their physical and mental health. The primary aim of this study was to examine the effectiveness of a walking exercise intervention in improving physical fitness, body mass index, waist-to-hip ratio, and depressive symptoms in patients with schizophrenia. A quasi-experimental study design was used. Seventy-six participants were recruited from the psychiatric daycare center at a hospital in Northern Taiwan. They were divided into two groups. The intervention group received a walking exercise intervention, while the control completed their daily courses at the psychiatric daycare center. The changes in both groups' physical fitness, BMI, waist-to-hip ratio, and depressive symptoms were monitored. Cardiorespiratory endurance significantly improved in the intervention group, attesting to the effectiveness of the walking exercise intervention. Their depression level significantly decreased across all measurement stages. The group walking exercise reduced sedentary behaviors and increased the participants' autonomous motivation, hip circumference, and cardiorespiratory fitness. Structured exercise programs may increase the patients' hippocampal neuroplasticity and reduce their depressive symptoms. The walking exercise intervention positively affected physiological traits, physical fitness, and mental health of the participants.

Exercise behaviours and motivation after a first psychotic episode: A digital intervention

AIM

Research has demonstrated that participation in aerobic exercise can have significant beneficial effects across both physical and mental health domains for individuals who are in the early phase of schizophrenia. Despite these notable benefits of exercise, deficits in motivation and a lack of methods to increase engagement are significant barriers for exercise participation, limiting these potentially positive effects. Fortunately, digital health tools have the potential to improve adherence to an exercise program. The present study examined the role of motivation for exercise and the effects of an automated digital text messaging program on participation in an aerobic exercise program.

METHODS

A total of 46 first-episode psychosis participants from an ongoing 12-month randomized clinical trial (Enhancing Cognitive Training through Exercise Following a First Schizophrenia Episode (CT&E-RCT)) were included in an analysis to examine the efficacy of motivational text messaging. Personalized motivational text message reminders were sent to participants with the aim of increasing engagement in the exercise program.

RESULTS

We found that participants with higher levels of intrinsic motivation to participate in a text messaging program and in an exercise intervention completed a higher proportion of individual, at-home exercise sessions. In a between groups analysis, participants who received motivational text messages, compared to those who did not, completed a higher proportion of at-home exercise sessions.

CONCLUSION

These results indicate the importance of considering a person's level of motivation for exercise and the potential utility of using individualized and interactive mobile text messaging reminders to increase engagement in aerobic exercise in the early phase of psychosis. We emphasize the need for understanding how individualized patient preferences and needs interplay between intrinsic motivation and digital health interventions for young adults.

Treatment engagement in first-episode schizophrenia: Associations between intrinsic motivation and attendance during cognitive training and an aerobic exercise program

Systematic cognitive training and aerobic exercise programs have emerged as promising interventions to improve cognitive deficits in first-episode schizophrenia, with successful outcomes closely linked with greater treatment engagement (e.g., higher attendance and homework completion rates). Unfortunately, treatment disengagement from these services remains a persistent issue. Intrinsic motivation, or the willingness to exert effort because a task is inherently interesting or meaningful, has emerged as a promising malleable personal factor to enhance treatment engagement. This study investigated whether early task-specific intrinsic motivation and its domains (e.g., interest, perceived competence, and value) predicted treatment engagement within the context of intensive cognitive training and aerobic exercise interventions over a 6-month period. Thirty-nine participants with first-episode schizophrenia were administered baseline measures of task-specific intrinsic motivation inventories, one for cognitive training and one for exercise, and completed a 6-month randomized clinical trial comparing a neuroplasticity-based cognitive training plus aerobic exercise program against the same cognitive training alone. Results indicated that higher baseline scores of intrinsic motivation for cognitive training, specifically early perceptions of task interest and value, were predictive of greater cognitive training and exercise group attendance. Scores for exercise-specific intrinsic motivation were generally unrelated to indices of exercise participation, with the exception that the gain over time in perceived choice for exercise was linked with greater exercise homework completion and a similar directional tendency for greater in-clinic exercise attendance. This study provides support for monitoring and enhancing motivation early during service delivery to maximize engagement and the likelihood of successful treatment outcomes.
