This work extends prior research, the first stage of which involved the Polish cultural adaptation of the Family Leisure Activity Profile questionnaire.\n\n\nMethod\nThe scale structure was subjected to confirmatory factor analysis (CFA). CFA demonstrated a good fit of the model to the data based on a sample of 494 Polish individuals from 247 families, including parents and children (aged 11–16 years).\n\n\nResults\nAll fit indicators were satisfactory, allowing the two models to fit the data very well: comparative fit index (CFI) = .93 to .94 (Model 1) and CFI = .92 to .95 (Model 2); Tucker–Lewis index (TLI) = .91 to .92 (Model 1) and TLI = .91 to .93 (Model 2); standardized root mean squared residual (SRMR) = .063 to .069 (Model 1) and SRMR = .062 to .070 (Model 2); root mean square error of approximation (RMSEA) = .077 to .82 (Model 1) and RMSEA = .072 to .077 (Model 2). The results show a high level of internal consistency: Cronbach's α = .92 to .93, intraclass correlation coefficient (2 k) = .91 to .94.\n\n\nConclusion\nThe results confirm that the scale retains its original single‐factor structure, which is essential for its applicability to different cultural settings.\n\n\nImplications\nBy confirming the scale's validity and reliability, this research contributes to the broader field of family leisure studies in Poland and supports initiatives to enhance family cohesion through shared activities. It will probably be used as a basis for future international studies of family assessment tools.\n\n"]
