The park physical activity questionnaire (Park-PAQ): A reliable measurement tool for park-based and total physical activity

Abstract

Background: Few studies have explicitly quantified the proportion of park-based physical activity to park users' overall physical activity levels. Population studies need new context-specific physical activity measurement tools to achieve this. The objective of this study was to develop a reliable measure of self-reported park use and physical activity undertaken within and outside of parks to determine the contribution that park-based physical activity makes to overall physical activity levels.

Methods: A test-retest reliability study (n = 104) was conducted using the Park Physical Activity Questionnaire (Park-PAQ), an instrument based on the Active Australia Survey. Park-PAQ items captured the frequency and duration of walking for recreation or exercise, walking for transport, moderate and vigorous physical activity and strength, conditioning and balance activities done in parks and elsewhere.

Results: Recall of doing any walking for recreation (kappa = 0.649, p < 0.001) and any vigorous physical activity (kappa = 0.772, p < 0.001) was 'substantial', recall of doing any moderate physical activity (kappa = 0.553, p < 0.001) was 'moderate/acceptable', and recall of any walking for transport (kappa = 0.840, p < 0.001) 'near perfect'. Recall of the time spent walking for recreation in parks (ICC = 0.928, p < 0.001) was 'near perfect', whilst recall of time spent doing moderate activity in parks (ICC = 0.925, p < 0.001) and vigorous activity in parks (ICC = 0.962, p < 0.001) was 'near perfect'. Time spent walking for transport in a park (ICC = 0.200, p = 0.056) showed 'poor' agreement. Repeatability of the usual level of park use was 'substantial' (kappa = 0.744).

Conclusions: The Park-PAQ reliably measures six domains of physical activity and quantifies the proportion of physical activity done in parks as a proportion of total physical activity. The Park-PAQ, used alone or embedded into park or physical activity surveys, will reliably capture context-specific activities that will optimise population level physical activity interventions, park programming and park management and design.
