Psychometric Properties of Roy s Adaptation Questionnaire on Veterans with Lower Limb Amputation

Aims: The Roy Adaptation Pattern is a useful way to involve patients with amputation in the treatment processes. This study aimed to psychometry the Roy adaptation questionnaire on veterans with lower limb amputation. Instrument Methods: This descriptive study was carried out on 325 veterans with lower limb amputation referred to the Veterans Clinic of the Kosar Orthosis and Prosthesis Center in Tehran in 2018. Data were collected by the Roy Adaptation Model and a demographic questionnaire. Data were analyzed using SPSS 22 software through sampling adequacy index and Bartlett #39;s sphericity test, and the method of exploratory factor analysis. The reliability of the questionnaire was also assessed by the testretest method and the instrument #39;s internal consistency. Findings: The final questionnaire consisted of 20 items in four physiological dimensions: selfperception, dependence/independence, and roleplay. The results of exploratory factor analysis showed that the four factors represent 47.57% of the variances. In determining reliability, the agreement between testretest responses in terms of intracluster correlation (ICC) for the whole instrument was 0.911. The Cronbach #39;s alpha value of the questionnaire was calculated to be 0.876. Conclusion: The Roy adaptation questionnaire can examine different dimensions of adaptation in veterans with lower limb amputation and can increase their adaptability and quality of life.
