This study aims to identify the determinants associated with physical activity (PA) behavior in newly diagnosed obstructive sleep apnea (OSA) patients by applying the Health Action Process Approach (HAPA) with a longitudinal design. Anthropometric and clinical (OSA severity, subjective somnolence, use of continuous positive airway pressure (CPAP)) variables, the determinants of physical activity specified in the HAPA (motivational self-efficacy, outcome expectancies, risk perception, intention, maintenance self-efficacy, action planning, coping planning, social support), as well as physical activity behavior were assessed using a longitudinal (T1 and T2) design in a sample of 57 OSA patients in routine care. Applying regression analyses, regarding the motivation phase, the amount of explained variance in intention was 77% and 39% of the variance in physical activity. In the motivational phase, motivational self-efficacy , risk perception and outcome expectancies were associated with intention. In the volitional phase, physical activity at T1 and social support (family) were related with physical activity at T2. In conclusion, the assumptions of HAPA were partially found in the context of newly diagnosed OSA patients. This study provided additional evidence regarding the role of motivational self-efficacy, outcome expectancies and risk perception during motivational phase, and highlighted the important role of social support from the family in the PA in this population.
