Development of the Rural Active Living Perceived Environmental Support Scale (RALPESS).

BACKGROUND Evidence supports the role of physical and social environments in active living, including perception of environment. However, measurement of perceived environments in rural settings is lacking. This study describes the development of the Rural Active Living Perceived Environmental Support Scale (RALPESS). METHODS Premised on social ecological and cognitive perspectives, 85 initial items were generated through a literature review and a mixed-methods investigation of "activity-friendly" environments. Items were organized by resource areas--town center, indoor and outdoor physical activity areas, schools, churches, and areas around the home/neighborhood--and submitted for expert panel review. In 2009, a revised questionnaire was disseminated to adolescents, parents, public school staff, and older adults in 2 rural southeastern United States counties. Principal component analysis with varimax rotation was used to explore factor structure (n = 542). RESULTS The final analysis yielded 33 items with 7 factors: 1) church facilities, 2) town center connectivity, 3) indoor areas, 4) around the home/neighborhood, 5) town center physical activity resources, 6) school grounds, and 7) outdoor areas. CONCLUSIONS The RALPESS is a valid, internally consistent, and practically useful instrument to measure perceptions of rural environments in the context of physical activity across the lifespan. Confirmatory factor analysis is recommended to validate factor structure.
