Psychometric properties of the theory-based clinical behavioral intention scale among Turkish community pharmacists

Abstract

The aim of this study was to assess psychometric properties of a theory-based scale, which can be used to identify and evaluate clinical behavioral intentions of Turkish community pharmacists. For the Turkish version of the theory-based scale; translation, cultural adaptation, and a pilot study were carried out, respectively. Intraclass correlation coefficient (ICC) was calculated in 31 pharmacists for the two-week test-retest reliability. Online survey was conducted among community pharmacists in seven regions of Turkey between May and August 2021 by using convenience sampling. Principal component analysis was performed with Varimax rotation. Cronbach's alpha coefficient was calculated for each component and the total scale. Among one hundred twenty-seven pharmacists, the median age was 44.0 (ranged between 23 and 72 years). In the two-week test-retest reliability analysis, reliability in the total scores of the scale between the baseline and after 15 days was excellent (ICC= 0.938; p<0.001). Three components were identified in the principal component analysis, with 72.7% of the total variance explained. Cronbach's alpha values ranged from 0.765 to 0.909. The Turkish version of this theory-based scale can be used to identify and evaluate clinical behavior intentions of Turkish community pharmacists. Further studies can be conducted to evaluate the validity of scale among diverse healthcare providers to assess their intention to various behaviors.
