Abstract
Aims: Evaluation of Patient Satisfaction (PS) is one of the most essential factors in improving the quality of healthcare systems. The aim of this study is to determine the norms and to evaluate the validity and reliability of the Najmiyeh Outpatients Satisfaction Questionnaire (NOSQ). Methods and Materials: This study has been conducted on 240 outpatients in Najmiyeh subspecialty hospital (Tehran-Iran) in 2011. They were selected using the proportional simple random sampling method. Following the confirmation of the content validity, we considered the construct validity and reliability applying Confirmatory Factor Analysis (CFA) and Explanatory Factor Analysis (EFA) and Cronbach's Alpha. Also, SPSS and AMOS version 18 were used for data analysis. Findings: The sample population consisted of 240 subjects, including 132 females (55.1%) and 108 males (44.9%). The EFA reported three important factors in this regard, with a variance of 54% and Kaiser-Meyer-Olkin index of 0.82, all approved by the CFA (RMSEA= 0.04, CFI= 0.96). The outpatients' satisfaction factors were: “hospital information system, treatment and conditions”. The reliability of the questionnaire was reported at %71 based on the Cronbach's alpha. Conclusions: Both validity and the reliability indexes of the NOSQ have been reported at a desirable level; therefore it can be used as a valid and reliable instrument to measure the outpatients' satisfaction.
