Abstract
Aim: Patients' satisfaction (PS) is a dominant concept in medical care, due to the gap in the literature on Persian version of PS instruments, this study has conducted with aim to analyze the validity and reliability of self-designed Najmiyeh Inpatient Satisfaction Questionnaire (NISQ). Methods: This study was carried out on 247 inpatients that came in Najmiyeh subspecialty hospital in Tehran (the capital city of Iran) during year 2011 who were selected by proportional stratified sampling method. Statistical analysis used: In this study, after checking content validity we used confirmatory and explanatory factor analysis and Cronbach's Alpha in order to examine construct validity and reliability, respectively. SPSS (version18) and AMOS (version 20) programmer were used to analyze data. Findings: Samples consisted of 247 subjects (222 women (90%) and 25 men (10%)). The explanatory factor analysis showed 5 factors with 64% total variance and 0.91 Kaser-Meyer-Olkin Index, the result also confirmed with confirmatory factor analysis (PNFI=0.71, RMR=0.03, PCFI=0.76). Extracted factors consisted of: “satisfaction from nursing services and their behaviour”, “satisfaction from one’s doctor”, “satisfaction from inpatient department”, “companions’ satisfaction”, “satisfaction from one’s room”. Also the questionnaire’s reliability was 0.96 using the Cronbach's Alpha method. Conclusions: Because validity and reliability indexes of NISQ were reported in suitable range, we can confirm that this questionnaire is a valid and reliable tool for measuring inpatient satisfaction.
