Background: Children’s play and leisure participation is often assessed by occupational therapists. As such, it is essential that therapists utilize play and leisure scales that are valid, reliable and responsive. Aim: To examine the convergent validity between the Children’s Leisure Assessment Scale (CLASS) and Children’s Assessment of Participation and Enjoyment and Preferences for Activities of Children (CAPE/PAC). Methods: Forty healthy Australian children (60% female; mean age 9.2 ± 2.01 years) completed the CLASS and CAPE/PAC. Spearman’s rho correlations with bootstrapping were completed. Results: A number of the CLASS and CAPE/PAC subscales were significantly correlated. The CAPE’s overall scale scores and CLASS’s instrumental indoor activities, outdoor activities and games and sport activities subscales were significantly correlated (p > 0.05). The CAPE’s Social domain showed several significant correlations with the CLASS’s instrumental indoor activities, outdoor activities and self-enrichment activities domains (p < 0.05). Statistically significant relationships were found between the CLASS’s outdoor activity preference and the PAC’s recreational, physical, formal, informal and overall performance scores (r = 0.466–0.773, p < 0.05). Conclusions and Significance: Preliminary evidence in support of the convergent validity between the CAPE/PAC and CLASS was obtained. Limitations include a small sample size and convenience sampling. Further investigation of the psychometric properties of the CAPE/PAC and CLASS are recommended.
