碩士 === 國立臺灣大學 === 護理學研究所 === 91 === ABSTRACT The purpose of this study was to develop the Taiwanese version of Lancashire Quality of Life Profile. This scale combine objective and subjective measures in nine life domains: work, leisure, religion, finance, living situation, legal and safety, family relations, social relations, health, general well-being, affect, and self-concept. We established the reliability and validity of the Taiwanese version of this scale, and found the relationship between the demographic factors, psychotic symptoms, care settings, and quality of life in schizophrenia. The data were collected by conducting structured interview with 100 subjects purposively sampled who were admitted to the rehabilitation center or outpatients at a university hospital in Taipei. We tested psychometric properties which included internal consistency, criterion -related validity, construct validity, and discriminate validity. Thirty patients were interviewed again within 2 weeks to verify test-retest reliability. The result showed that： 1. The internal consistency (Cronbach’s α) of the Life Satisfaction Scale (LSS) was good at 0.87, and that the sub-scales ranged from 0.53-0.82 for the nine domains. The test-retest reliability ICC score for LSS was good at 0.91, and the nine subjective quality of life (QOL) domain sub-scales it range from 0.60-0.92. 2. We used SF-36 and three items from Lancashire Quality of Life Profile as the criterion-related validity tool. The Taiwanese version of Lancashire Quality of Life Profile had significant correlations with the two scales. 3. Exploratory factory analysis revealed six factors： family relations, health and safety, finance, autonomy and well-being, social relations, and leisure. These six factors can explain 54.14% of the variance. 4. Multiple domains and sub-scale could significantly discriminate severity of psychotic symptoms and subjective quality of life correlations, except for work and family domains. 5. In nine subjective QOL domains, highest satisfaction domain was family relations, and lowest satisfaction domains were work and finance. Between those who were admitted to the rehabilitation center and who were followed at outpatient center, there were significant different in three domains of subjective QOL (living situation, social relations, and health), life at present score, total subjective QOL score and two domain sub-scales of objective QOL (work and finance). 6. Multiple regression model revealed that the best factors of predicting subjective quality of life were emotion symptoms, care setting, age range of 20-30, separated marital status, and negative symptoms. This model explained 45.5% of variance. The study result cold contribute to the evaluation of subjective and objective QOL in patients with schizophrenia and being used as basis of future local data gathering, cross-cultural comparison, and establishment of psychiatric care policy.
