Theis study was conducted to understand the needs of in-patients' families and the satisfaction of these needs during their visits to hospital wards, in terms of the hospital environment and the service they received from hospital staff, as well as to elicit any factors that may influence these needs. The structure of the questionnaire was designed in January of 1996 after thorough research of both Chinese and English publications. The questionnaire was then developed using modifications from Molter (1979) and Rau (1988). After testing for confidence and efficacy, 355 effective samples were obtained between June 15 and July 30, 1996, and calculation of percentages, means, standard deviations, ANOVA values, and other appropriate of statistical value were performed. Results show that among "Five Basic Needs Categories" (1.obtaining relevant information on the patient's disease, 2. obtaining nursing care instructions, 3. receiving psychological or emotional support and consolation, 4. being able to visit and help the patient, and 5. hospital environment and facilities), both "obtaining relevant information on the patient's disease" and "obtaining nursing care instructions" ranked as most important, while "receiving psychological (emotional) support and consolation" received a lower score. The mean score for the five categories was 3.27 (out of a total of 4 points). Satisfaction scores were higher for "being able to visit and help the patient" (2.55 out of a total of 3 points) while scores were lower for "hospital environment and facilities" (2.31). The "Needs in Five Basic Categories" were also ranked differently by families of in-patients in the adult wards than by those of inpatients in the pediatric wards.
