Background: Individuals with mental disorders (MDs) face a higher mortality risk because of unaddressed lifestyle factors contributing to metabolic syndrome (MetS). While general multimodal lifestyle interventions (MLIs) show promise, they are not tailored to patients with MDs. Objective: Assess the impact of the MLI LEEF!, tailored to people with MDs in an outpatient setting on both objective and subjective physical activity and sleep utilizing MotionWatch actigraphy and standardized self-report tools. Methods: In this 18-week open pilot intervention study, 33 participants with anxiety or affective disorders and MetS completed the MLI LEEF! Twelve participants wore the MotionWatch pre- and post-intervention. MotionWatch data and subjective data (insomnia severity index (ISI) and a question on physical activity) were collected at multiple intervention timepoints. These parameters were compared and differences, correlations, and potential predictors of outcome on objective data were explored. Results: The objective sedentary time significantly increased from 406.7 (SD = 120.31) to 717.8 (SD = 325.59) minutes per day pre- and post-intervention, respectively, while objective physical activity and subjective data showed no differences. Objective sleep parameters remained unchanged over time, while subjective insomnia severity scores significantly decreased. Predictors of outcome indicate that at baseline 1) females, 2) lower BMI, and a 3) higher waist circumference were predictors of improved activity outcomes. Conclusion: Objective activity and sleep outcomes differed from subjective outcomes and were not significantly correlated, highlighting disparities between perceived and actual outcome parameters of the MLI. Future studies should incorporate an intervention control group for exploring specific intervention effects and include a daily diary to improve the interpretation of activity and sleep data.
