RESUMO
OBJECTIVE: This paper discusses some of the inherent methodological limitations of gathering data via direct observation using local parks as a case study. METHODS: Direct observation was carried out in five parks on seven non-consecutive days in 1998 and on matched days in 1999. Information recorded for each person included the time of park entry and exit, gender, age group, and activity/ies undertaken while in the park. METHODOLOGICAL CONSIDERATIONS: The location of the observation point, observer reliability, recording and accuracy of data, and specific issues related to outdoor observation areas should all be considered when designing a study incorporating direct observation as a data collection method. CONCLUSIONS: Direct observation can provide valuable information. However, pilot testing is essential for minimising potential problems associated with this method and optimising data quality. IMPLICATIONS: The issues discussed in this paper provide a useful guide for other researchers undertaking direct observation in outdoor environments.
