Purpose: Optimism is an important psychological variable that functions positively in stress adaptation process. The purpose of this study was to identify either a mediating or moderating effect of optimism in the relationship between stress and well-being among mothers of children with diabetes mellitus. Methods: A sample of 109 mothers of children with diabetes mellitus was recruited in a tertiary hospital in B city and they completed self-reported questionnaires. Multiple regression analysis models were used to test the mediating and moderating effects of optimism in the relationship between stress and well-being. Results: The results of the multiple and hierarchical regression analysis showed that the role of optimism was examined a partial mediator of the relation between stress and well-being, not a moderator. Increased stress was associated with decreasing optimism and well-being, and increased optimism predicted increased well-being among mothers of children with diabetes mellitus. Conclusion: Optimism is more likely to play a role as mediator, rather than as a moderator. This finding suggests the importance of optimism in improving the well-being of mothers of children with diabetes mellitus.

Results: There was a fully mediating effect of happiness in the relationship between internet addiction and suicidal ideation of the adolescents from multicultural families (F=6.65, p<.001). There was a partial mediating effect of happiness in the relationship between depression and suicidal ideation of the adolescents from multicultural families (F=10.01, p<.001).

Purpose: The purpose of this study is to explore the roles and function of family in mediating the relationship between depression and quality of life of patients with Parkinson's disease (PD). Most studies have found that depression is particularly common in patients with PD and further associated with poor quality of life. Family function, as a mediator, is based on a strength orientation perspective that emphasizes not only their responsibilities and risks but also recuperative powers and growth potential. Methods: Overall 157 adults with idiopathic Parkinson's disease were enrolled in this study via outpatient clinic and completed a set of assessment to measure depression using BDI, family APGAR questionnaire, and patients' quality of life using PDQ-8. Hierarchical multiple regression analysis was conducted to examine the mediating role of family APGAR score in the relationship between BDI and PDQ-8. Results: Patients' depression, gait disturbance, duration of illness, and family function were statistically significant on quality of life. These factors accounted for 60% of the variance in quality of life. Family function has a partial mediating effect on the relationship between depression and quality of life. Conclusion: Findings from the study suggest that although PD patients' depression impacts their quality of life, by having strong family function, the extent to which depression impacts the quality of life can be favorably mitigated. Additionally, these outcomes have important implications for future model development regarding PD patients.

Purpose: The purpose of this study was to investigate the mediating effect of perceived appraisal support between neuroticism and occupational stress in firefighters. Methods: The subjects of this study were 156 firefighters who worked at three fire stations in G province in Korea. The collected data were analyzed by t-test, ANOVA, and multiple regression analysis using Baron and Kenny's method for mediation. Results: There were significant relationships between neuroticism and perceived appraisal support (r=.30, p<.001), neuroticism and occupational stress (r=.42, p<.001), and perceived appraisal support and occupational stress (r=.36, p<.001). Perceived appraisal support showed partial mediating effects in the relationship between neuroticism and occupational stress. Conclusion: The impact of neuroticism in firefighters was mediated by perceived appraisal support for occupational stress. This suggests that strategies for enhancing perceived appraisal support in fire fighters should be considered when developing neuroticism management interventions for decreasing their occupational stress.
