The Patient Satisfaction with Pharmacist Services Questionnaire (PSPSQ 2. 0) translation and validation study of the Urdu version

The study aimed to examine the psychometric properties of the Urdu version of Patient Satisfaction with Pharmacist Services Questionnaire (PSPSQ 2.0). We applied the forward-backward procedure to translate the PSPSQ 2.0 in the Urdu language. The test-retest reliability was assessed through Cronbach's alpha reliability analysis. The 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. The Quality of Care (QOC) construct exhibited Cronbach's alpha values of 0.900 (Test) and α = 0.871 (Retest) at two-time points. The Interpersonal Relationship (IPR) Construct had alpha values of 0.845 (Test) and α = 0.819 (Retest). 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. Two factors explaining the total variance of 40% were extracted whereby loading values were acceptable (> 0.50) for all items of the translated version of PSPSQ 2.0. Results of this study conclude that the translated version of PSPSQ 2.0 is a valid instrument in regions where Urdu is a prime language of communication

Inherent irreversibility impacts on thermal boundary layer flow over a mobile plate with convective surface boundary conditions

Background:The irreversibility impacts on flow and heat transfer processes can be quantified through entropy analysis. It is a significant tool which can be utilized to deduce about the energy losses. The current study investigates the inherent irreversibility impacts during a flow of boundary layer and heat transfer on a mobile plate. Methods:The flow is examined under thermal radiation and convective heat conditions. The fundamental governing equations of flow and heat phenomenonare transmuted into ordinary differential equations by employing similarity transmutations and shooting technique is utilized in order to solve the resultant equations. The temperature and velocity profiles are acquired to reckon Bejan and entropy generation number. Pertinent results are elucidated graphically for the movement of plate and flow in same and opposite directions.Results:A decline in temperature profile is noted with rise in values of Prin both cases when the movement of surface and free stream is in similar and converse directions. A decrease in temperature is observed for both cases with increase inNRwhile with the rise in Biot numbera, the temperature profile also increases. Entropy generation rate near the surface is high in case when surface and free stream are moving in opposite directions as compared to case when they move in same directions.Conclusions:It is observed that irreversibility impacts are more remarkable when the movement of fluid and plate is in opposite direction. Moreover, irreversibility impacts of heat transfer are prominent in free stream region.
