METHODS: The study, which spanned 10 months, involved a cross-sectional survey of 303 community pharmacists across Arabic-speaking nations. The translation process followed the standard "forward-backward" technique from English to Arabic. Validation employed confirmatory factor analysis (CFA) and structural equation modeling, with indices like root mean square error of approximation (RMSEA), incremental fit index (IFI), normed fit index (NFI), McDonald's fit index (MEI), and comparative fit index (CFI). Convergent validity was assessed using average variance extracted (AVE) and composite reliability (CR), while discriminant validity was evaluated through latent factor correlation in the three-factor model against the square root of AVE values. Reliability was gauged using Cronbach's alpha and the intraclass correlation coefficient (ICC).

RESULTS: CFA confirmed the Professional Collaborative Practice Tool's structural validity in Arabic. The model's robustness was indicated by fit indices (CFI: 0.974, NMI: 0.954, IFI: 0.974, MEI: 0.887, RMSEA: 0.063). AVE values exceeding 0.50 validated the explanatory power of the latent constructs. CR values (≥0.70) indicated strong internal consistency and reliability. The tool demonstrated superior discriminant validity, with lower inter-factor correlations than the square root of AVE values. High Cronbach's alpha coefficients (>0.70) across all factors and the model reflected excellent internal consistency. The ICC (0.95) suggested exceptional long-term reliability.
