Confirmatory factor analysis (CFA) conducted, structural equation model (SEM) developed. Fit indices, namely, goodness fit index (GFI), adjusted (AGFI), Tucker Lewis (TLI), comparative (CFI), root mean square error approximation (RMSEA) reported. Reliability assessed using Cronbach’s alpha (α), intraclass correlation coefficient (ICC), corrected item-to-total (ITC) item deletion. Data analysed through IBM SPSS 23 AMOS 25. obtained ethical clearance. Results: A total 150 responses analysed. reliability (α) = 0.696. (ICC) reported at 0.696 (95% CI: 0.618–0.763). values indices as follows: χ 2 /df 1.84, GFI 0.918, TLI 0.920, CFI 0.942, AGFI 0.864, RMSEA 0.075. except acceptable ranges indicated good fitness. Most participants (80.7%) appeared non-adherent medications. Conclusion: results demonstrate that valid reliable measure persons
