Measuring quality of health care from the user's perspective in 41 countries: Psychometric properties of WHO's questions on health systems responsiveness
Quality of Life Research , Volume 16 - Issue 7 p. 1107- 1125
Objective: To evaluate, for different populations, psychometric properties of questions on "health systems responsiveness", a concept developed by World Health Organization (WHO) to describe non-clinical and non-financial aspects of quality of health care. Data sources/study setting/data collection: The 2000-2002 WHO Multi-Country Study comprised 70 general population surveys. Forty-one surveys were interviewer-administered, from which we extracted respondent records indicating ambulatory and inpatient health services use (excluding long-term institutions) in the previous 12 months (50,876 ambulatory and 7,964 hospital interviews). Study design: We evaluated feasibility, reliability, and construct validity using 33 items with polytomous response options, comparing responses from populations identified by countries, sex, age, education, health and income. Principal findings: Average item missing rates ranged from 0 to 16%. Domain-specific alpha coefficients exceeded 0.7 in 7 (of 9) cases. Average intertemporal reliability was acceptable in 6 (of 10) sites, where Kappas ranged from 0.54 to 0.79, but low in 4 sites (K < 0.5). Kappa statistics were higher for male, educated and healthier populations than for female, less educated and less healthy populations. Factor solutions confirmed the domain structure of 7 domains (only 7 were operationalized for ambulatory settings). As in other studies, higher incomes and age was associated with more positive responsiveness reports and ratings. Conclusions: Quality issues addressed by WHO's questions are understood and reported adequately across diverse populations. More research is needed to interpret user-assessed quality of care comparisons across population groups within and between countries.
