Multidimensional Analysis of the Arabic Version of the Actual Scope of Nursing Practice Scale.

BACKGROUND AND PURPOSE: Data were analyzed from a national convenience sample of 3,000 bedside nurses in Lebanon to evaluate the psychometric characteristics of the first Arabic version of the Actual Scope of Nursing Practice (A-ASCOP) questionnaire.

METHODS: The method used in this study was application of the partial credit model using the multidimensional random coefficients multinomial logit model.

RESULTS: A-ASCOP subscales ( r = .81-.94) and levels of item complexity ( r = .95-.98) were highly correlated.

CONCLUSIONS: As a 26-item scale, the A-ASCOP has high internal consistency (Cronbach's α = 0.93). The A-ASCOP subscales have acceptable multidimensional reliability Expected A-Posteriori/Plausible Value ratio (EAP/PV > .80) and are suitable for descriptive surveys. The three A-ASCOP levels of item complexity were not valid for this sample. We report norms for unidimensional Rasch and 0-100 transformed measures by category of participant.
