  abstract  = {IntroductionWhile physical activity (PA) can play an important role in the treatment of mental disorders (MD), large proportions of patients with MD do not meet PA recommendations. The aim of this trial was to evaluate whether structured psychological intervention (MoVo-LISA) is effective in helping outpatients with MD to increase their level of PA. As active control group (CG) we modified MoVo-LISA to target healthy diet behavior.MethodsN=83 outpatients with MD (F1-F4) were randomized to the two conditions. PA (self-report and accelerometry), dietary behavior, social-cognitive determinants of health behavior change, psychiatric symptoms and health-related quality of life were assessed at baseline, 1 and 12 weeks after the intervention.ResultsSignificant time*group interaction effects for objectively measured PA, dietary behavior and fruit and vegetable consumption indicated differential effects of the interventions on these outcomes. PA increased in the MoVo-LISA group (IG) from baseline to follow-up while it decreased in CG. IG showed a significant higher level of objectively measured PA at follow-up compared to CG. Dietary behavior and fruit and vegetable consumption significantly increased from baseline to follow-up in CG, but not IG. IG showed a significant increase in some, but not all social cognitive determinants of health behavior change.ConclusionsMoVo-LISA is effective in helping outpatients with MD to increase their level of PA in short- and mid-term. The used intervention strategies are effective for the promotion of healthy diet in patients with MD as well.},

  abstract  = {Physical activity (PA) can play an important role in improving the mental and physical health in patients with mental disorders but is not well studied in this population. The aim of this study was to assess the status of PA in outpatients with mental disorders, compare the convergence of self-rating and accelerometer measurement and examine the influence of social cognitive variables from the Motivation-Volition (MoVo) model and clinical measures on PA. Eighty-four patients were recruited from three psychiatric outpatient clinics and local psychiatrists (Distribution of ICD-10-Diagnoses: F3.x = 59.5\%, F4.x = 20.2\%, F2.x = 17.9\%, F1.x = 2.4\%). PA, Self-efficacy, Outcome-expectancies, Intention, Self-concordance, Action- and Coping-planning, Health-related Quality of Life (SF-12) and Psychiatric Symptoms (SCL-27) were assessed through questionnaires. PA was assessed objectively by accelerometers. Most of the participants did not reach PA recommendations. Subjective and objective measurement of PA showed good accordance for total PA on group level but lower accordance on individual level. Motivational and volitional determinants of health behavior change showed a similar pattern of correlations with PA as in populations without mental disorders. Outpatients with mental disorders have the ability and are willing to perform PA but a large proportion of our sample did not meet PA recommendations. To assess group levels of PA, subjective and objective measurement seem equally apt, for individual diagnostics, a combination of both should be considered. Social cognitive determinants of health behavior change seem to be as helpful for the design of PA interventions for patients with mental disorders as they are in other populations.},
