= 4.11) participated in the online survey. This study employed Structural Equation Modeling to examine the interrelationships among the proposed variables. The findings indicated a significant negative association between perceived barriers and PA participation intention and a significant positive association between self-efficacy and PA participation intention. Furthermore, intention was positively associated with PA and accounted for indirect associations linking perceived barriers and self-efficacy with PA. Overall, these findings suggest that perceived barriers and self-efficacy are salient belief domains linked to PA intention and behavior. Practical implications include further interventions to reduce perceived barriers and enhance self-efficacy to promote sustained PA engagement among older adults.
