Abstract
BACKGROUND: The RESIDential Environment project (RESIDE) is a longitudinal study evaluating the impact of a new residential design code on walking. OBJECTIVE: To develop a reliable measure of walking--undertaken within and outside the neighborhood--and overall physical activity. METHODS: A test-retest reliability study was undertaken (n = 82, mean age 39 years). The instrument was based on the International Physical Activity Questionnaire (IPAQ-short version) and Active Australia Survey. It measured usual frequency and duration of (1) recreational- and transport-related walking within and outside the neighborhood and (2) other vigorous and moderate physical activities. RESULTS: Reliability of recall of whether participants had walked within (k = 0.84) and outside (0.73) the neighborhood was acceptable. Similarly, recall of frequency and duration of transport and recreational-related walking within the neighborhood was excellent (ICC > or = 0.82), as was recall of transport-related walking trips outside the neighborhood (ICC > or = 0.84). Reliability for duration of recreational walking outside the neighborhood was fair to good (ICC = 0.55). The reliability of indices of total physical activity based on MET min/week (ICC = 0.82) and MET min/week dichotomized to 'sufficient' physical activity for health (kappa = 0.67) were both acceptable. CONCLUSIONS: The Neighborhood Physical Activity Questionnaire (NPAQ) is sufficiently reliable for studies examining environmental correlates of walking within the neighborhood.

Information about Development of Measure
The Neighborhood Physical Activity Questionnaire (NPAQ) was developed for the RESIDential Environment Project. The NPAQ was designed to capture walking undertaken locally and to be less influenced by weekly variations in behavior. Two versions of the NPAQ that differentiated between recreational and transport related walking were developed and sequentially assessed for test-retest reliability. Results from the first assessment informed development of the second instrument. The second version of NPAQ was modeled on the short version of the International Physical Activity Questionnaire (IPAQ) and the Active Australia Survey.

Data Collection/Protocol
For the first version of the Neighborhood Physical Activity Questionnaire, a convenience sample of participants recruited from metropolitan workplaces completed two instruments approximately one week apart. For the second (final) version, a convenience sample of participants drawn from general and academic staff at three universities completed two instruments approximately one week apart.
