OBJECTIVES

: To examine the psychometric properties of the Urdu version of Patient Satisfaction with Pharmacist Services Questionnaire (PSPSQ 2.0).

METHODS

We applied the forward-backward procedure to translate the PSPSQ 2.0 in Urdu language. The test-retest reliability was assessed through Cronbach’s alpha reliability analysis. Intraclass Correlation Coefficient (ICC) via One Way Random effects model with single measures was used to establish the stability of the construct measures. Validity of the translated PSPSQ 2.0 was constructed by using Confirmatory Factor Analysis (CFA) through principal axis factoring extraction and Oblique rotation with Kaiser Normalization onto 2 predetermined factors.

RESULTS

: One hundred and four patients completed the survey. The Quality of Care (QOC) construct with 10 items exhibited Cronbach’s alpha values of 0.900 (Test) and α = 0.871 (Retest) at two time points. The Interpersonal Relationship (IPR) Construct with 6 items had alpha values of 0.845 (Test) and α = 0.819 (Retest). Alpha values for all pooled 16 items were α = 0.900 (Test) and α = 0.890 (Retest) respectively. The Kaiser-Meyer-Olkin measure of sampling adequacy for the factor analysis was 0.899. Barlett’s Test of Sphericity was significant (Chi-square = 1192.72; p < 0.05) revealing relationships of the data and suitability of CFA. The ICC for most items tested for intra-rater (test-retest) reliability was good with majority of items exhibiting coefficients > 0.80. Two factors explaining total variance of 40% were extracted whereby loading values were acceptable (> 0.50) for all items of the translated version of PSPSQ 2.0.

CONCLUSIONS

Results of this study conclude that the translated version of PSPSQ 2.0 is a valid instrument and can be used to assess patients’ satisfaction with pharmacist services in regions where Urdu is a prime language of communication.
