Predicting psychological factors affecting regular physical activity in hypertensive patients: Application of health action process approach model.
Isa Mohammadi Zeidi, Hadi Morshedi, Abdollah Shokohi
PMID 33318852WHAT IT FOUND
Hypertensive patients' confidence in being active, perceived benefits, and perceived risk were linked to exercise intention.
Intention and coping confidence were linked to reported activity. These are associations, not proof that counselling will work.
Key findings
01The HAPA psychological constructs predicted 31% of variance in physical activity behaviour and 45% of variance in behavioural intention.
02Action self-efficacy, outcome expectancy, and risk perception were significant predictors of behavioural intention, with action self-efficacy strongest.
03Behavioural intention and coping self-efficacy were significantly associated with physical activity, while the direct path from planning to physical activity was not significant.

What it does not show
The study measured variables at one time, so it cannot show that psychological factors caused physical activity. Physical activity and psychological constructs were self-reported, so recall or social-desirability bias may affect the results. The sample was 176 patients from one city, and the authors say this was small for path analysis. Action planning and coping planning were combined in the model because using them separately did not fit, so the study does not clarify which planning component matters. The paper states that patients with primary hypertension receiving ACE inhibitors, angiotensin blockers, and beta-blockers were excluded, so the sample may not represent treated hypertension.
Declared interests
The authors declared no conflicts of interest. The study was funded by Qazvin University of Medical Sciences.
The easy way to misread this
Do not conclude that counselling on confidence, risk, or benefits will improve physical activity. The study was cross-sectional and self-reported, and planning was not directly linked to activity.
