Abstract
The purpose of the current study was to develop a more comprehensive theoretical framework in explaining the perceived quality of life (QoL) among people with mental illness, based on the model proposed by Rosenfeld (1992). The study examined the direct effect of employment, self-stigma and subjective symptom severity on perceived QoL, as well as the mediating effect of sense of mastery on the relations of employment, self-stigma and subjective symptom severity with QoL. A total of 80 participants with mental illness were recruited in the study. They were invited to complete a self-report questionnaire regarding their perceived QoL, self-stigma, subjective symptom severity, employment status and some other demographic information. The World Health Organization Quality of Life – Brief (WHOQOL-BREF), Devaluation and Discrimination scale, Kessler Screening Scale for Psychological Distress (K6), Mastery scale and working hours were used to measure the above captioned variables respectively. Results revealed that the direct effect of employment on psychological domain of perceived QoL was significant; the
significant direct effect of subjective symptom severity on the overall and the four domains of perceived QoL was also found. Meanwhile, the mediating effect of sense of mastery on the relations of employment and subjective symptom with perceived QoL was shown. The results of complementary analyses also demonstrated the significance difference of the tested variables between the employed and unemployed participants, as well as the participants with neurotic and psychotic disorders. The findings of the current study partially supported the direct effect of different variables on perceived QoL, and the mediating effect of sense of mastery on different variables. The findings supported the significance of subjective symptom severity and sense of mastery in understanding the perceived QoL among people with mental illness. Further investigation on the sense of mastery of people with different nature of mental illness is suggested.
