ABSTRACT
The present study aimed to examine the relationship of self-knowledge with quality of work life and mental health of high school managers in Nimrouz. This was a descriptive-correlational study, the statistical population of which consisted of all high school managers in Nimrouz in the 2014-15 academic year (N = 90). In this study, Rastogi’s Self-Concept Scale including 51 items, Mental Health Questionnaire containing 28 items, and Quality of Work Life Survey with 24 items were used. To determine the validity of these three questionnaires, content validity was applied. Moreover, using Cronbach’s alpha coefficient, their reliability was examined, for which the alpha coefficients were 0.89, 0.92, and 0.81, respectively. To analyze the obtained data, the Pearson correlation coefficient, regression analysis, independent t-test, and one-way analysis of variance were applied. Results indicated that self-knowledge was directly and significantly correlated with dimensions of quality of work life and mental health of managers. Additionally, there was a significant relationship between managers’ quality of work life and mental health. Findings demonstrated that self- confidence, sociability, and health and sex appropriateness were the best predicators of quality of work life and feeling of shame and guilt, abilities, and present, past, and future were the best predicators of mental health. Moreover, the level of self-knowledge, quality of work life, and mental health of male and female managers were alike. Considering managers’ level of education, a significant difference was found considering managers’ self-knowledge; however, no significant difference was found between quality of work life and mental health of managers. Given managers’ years of experience, a significant difference was observed with regard to managers’ self-knowledge and mental health.
