The BigMove Intervention for People With Physical and Mental Health Conditions: A First Evaluation of Self- Perceived Health, Quality of Life, Coping and Mental and Social Functioning

Background: The BigMove intervention aims to improve the functioning and quality of life of people with physical and mental health conditions via an integrated care approach. This pilot study evaluates the impact of the intervention on self-perceived health (SPH), quality of life (QoL), active coping behaviour, and mental and social functioning. Methods: Data were analysed from N = 457 participants who had been referred to the intervention by their general practitioner (mean age 48.98 years; 76% female). Three patient-reported and one clinician-rated measures were used: SPH, QoL (MANSA), active coping behaviour (UPCC-ACT), mental and social functioning (HoNOS). Pre- and post-intervention measurements (from 2011 to 2018) were compared using paired-samples t-tests. Due to missing data, analyses were conducted with 205-257 participants per completed outcome. Associations with age and sex were assessed using repeated-measures ANOVA. Clinically relevant change was evaluated with the Edwards-Nunnally index and standard error of measurement (SEM) scores. Results: Post-intervention, there were statistically significant improvements for all outcomes (p < 0.0001) with moderate to large effect sizes (d = 0.41 to 1.02). The observed changes in outcomes can be considered as clinically relevant improvements. Conclusion: This pilot study provides preliminary evidence that the intervention has positive effects on SPH, QoL, active coping behaviour, and mental and social functioning.
