Motivational coaching augmentation of exercise intervention for early psychotic disorders: A randomised controlled trial.

BACKGROUND

Exercise offers improvement to physical and mental health symptoms as well and cognitive function in patients with psychosis. However, patients with psychosis are often less ready to benefit from exercise intervention because of the difficulties in motivation. This study aimed to examine the effectiveness of adjunctive motivational coaching on exercise intervention in women with psychosis in Hong Kong.

METHODS

From a community mental health programme for women, patients with a diagnosis of psychotic disorder (within 5 years of first onset) were randomly allocated to receive 12 30-minute sessions of motivational coaching or psychoeducation in a group format. Both groups additionally received exercise intervention sessions consisting of yoga, stretching and high-intensity interval training. Primary outcome was the total physical activity level measured by the International Physical Activity Questionnaire.

RESULTS

Fifty-seven patients (mean [SD] age, 34.47 [12.44] years) were randomised into motivational coaching ( = 30) or psychoeducation ( = 27) treatment groups. The motivational coaching group had a significantly higher total physical activity level (4601.67 [686.59] vs 2524.82 [723.73] metabolic equivalent task-min/week, = 0.473, = 0.04) after the intervention and at 6 months post-intervention. Moderate and light physical activity levels were significantly higher in the motivational coaching group after intervention and at 6 months, respectively. Additionally, symptoms of bizarre behaviour were improved in the motivational coaching group at 6 months. Younger, unemployed, unmarried and those with longer durations of untreated psychosis generally showed larger improvements in the motivational coaching group.

CONCLUSION

Motivational coaching may augment the effects of exercise interventions, as reflected by higher physical activity participation. Motivational coaching augmentation has the potential to further improve exercise intervention outcomes.
