Patient satisfaction with hospital services: development and testing of a measuring instrument.
The present study was undertaken with the aim of developing and testing an instrument that could be used to measure patient satisfaction with hospital services in Kuwait. The instrument, which comprised 57 items, and measured satisfaction with 7 specific dimensions of hospital services, was administered to 493 patients using the interview technique. Statistical analysis showed that the instrument yields good response variability. Reliability of the instrument, measured in terms of the internal consistency coefficient alpha, exceeded the acceptable criterion level, the coefficients ranging between 0.73 and 0.86. Evidence of the construct validity of the instrument was found in significant positive correlation between the dimension specific satisfaction scale scores and scores for allegiance scale and for overall rating of quality of hospital services. Construct validity was further supported by convergent discriminant analysis, which showed that correlations between items of all 7 scales and their total scale scores were greater than correlations between scale items and the total scores of scales they do not represent. Analysis of an open-ended question about dissatisfying aspects of hospital services not included on the interview was undertaken to examine the instrument's content validity. Results indicated that patients identified 11 items, 8 of which were identified more than once, and 2 of which were not classifiable to the 7 dimensions assessed by the instrument. It was suggested to add the 8 items that were identified more than once, and to reassess the reliability and validity of the revised instrument. Assessment of the test-retest reliability, by comparing scale scores over time, was also suggested.
