The purpose of this study was to investigate patterns and factors related to 6- to 12-year-old children’s and their parents’ green space use behaviours in Çayyolu neighbourhood of Ankara, Turkey. Data were collected through draw and write surveys and questionnaire surveys at selected schools, and direct observations in eight parks in the neighbourhood. A total of 418 children and 383 of their parents participated in the surveys. In all, 498 recordings were made during on-site observations. Findings suggest that there is an interaction between park visiting patterns of parents and their children. Taking children to parks was a major motivation for – particularly female (p < 0.05) – parents to go outdoors. Most children (75%) used only gardens of their houses or housing complexes. There was a positive association between parents’ and children’s duration of visit (p = 0.00). Principal component analysis revealed three factors (52% of the total variance) effecting parents’ influence on their children’s use of green spaces; benefits of spending time outdoors, safety concerns and design characteristics. Results indicate that environmental design is not solely a factor in use of green spaces; understanding and promoting children’s use of green spaces should involve a holistic approach that includes social, cultural and physical aspects of the environment.
