The Relationship Between Socialism And Social Health Of Tibetan College Students: A Study Of Intermediary And Regulating Mechanism

Social identity is a deep consensus and pursuit. Basic mechanism of self-identity is the combination of macro social mentality and micro character. On the other hand, as a steady personal characteristic, optimism is a steady and positive cognitive disposition in reality and future. Foreign scholars make a lot of research on optimistic personality theory and its application. However, there is less research on the structure of optimism and social identity, the relation between optimism, social identity and mental health, and related mechanism Domestic scholars’research on optimism just starts. As a result, it is necessary to explore the structure and connotation of optimism under Chinese cultural background, find explanation of relevant findings of optimism, social identity and mental health by demonstration.The research tests 1027 Tibetan college students by questionnaire survey. It discusses the relation of optimism, social identity and mental health of college students. It also researches its intermediary agent and regulatory mechanism.Research findings:1. The fit index of social identity scale confirmatory factor analysis basically meet statistics requirement. Social identity scale includes four dimensions:belonging, emotional, active and evaluation identity. Cronbach a reliability coefficient is 0.862> 0.73^ 0.68^ 0.731 and 0.785 respectively. Social identity scale has good reliability and validity, which can be used as tools to test social identity.2. The fit index of optimism scale confirmatory factor analysis basically meet statistics requirement. Optimism scale has 23 items including three dimensions: optimistic tendencies, pessimistic tendencies and self-efficacy optimism. Cronbach α reliability coefficient of optimism scale, optimistic tendencies, pessimistic tendencies and self-efficacy optimism is 0.835、0.706、0.761 and 0.815 respectively. Optimism scale has good reliability and validity, which can be used as tools to test optimism.3. Social identity is the intervening variable of optimism and mental health. That is to say, social identity partially intervene optimism and positive mental health (life satisfaction, positive moods). Optimistic tendencies directly affect positive moods and life satisfaction; pessimistic tendencies directly affect life satisfaction and positive moods. Self-efficacy optimism directly affects life satisfaction and positive moods. Optimistic tendencies indirectly affect positive moods and life satisfactionby social identity. Pessimistic tendencies indirectly affect life satisfaction and positive moods by social identity. Self-efficacy optimism indirectly affects positive moods and life satisfaction by social identity. Significant path coefficient indicates that social identity has partial mediating effect.4. Social identity is the intervening variable of optimism and negative mental health (depression, anxiety). Optimistic tendencies directly affect depression. Pessimistic tendencies directly affect depression and anxiety. Optimistic tendencies indirectly affect depression and anxiety by social identity. Pessimistic tendencies indirectly depression and anxiety by social identity. Self-efficacy optimism indirectly affects depression and anxiety by social identity. Path coefficient of anxiety and optimistic tendencies is not significant; path coefficient of self-efficacy optimism, depression and anxiety is not significant, neither. According to checking formulas of Sobel, mediating effect of social identity to optimistic tendency and anxiety is significant. Mediating effect of social identity to self-efficacy optimism, depression and anxiety is significant. As a result, social identity has full mediating effect on optimistic tendency and anxiety; social identity has full mediating effect on self-efficacy and depression. It has partial mediating effect in other relations.5. Cultural adaptation has regulating effect on self-efficacy optimism and depression. The lower the cultural adaptation is, the bigger negative effect of self-efficacy optimism to depression is. That is to say, the lower the self-efficacy optimism is, the higher the depression is. Cultural adaptation has some regulating effect to self-efficacy optimism and life satisfaction. The lower the cultural adaptation is, the bigger positive effect of self-efficacy optimism to life satisfaction is. That is to say, the lower the self-efficacy optimism is, the lower the life satisfaction is.6. Stress has negative regulating effect to optimistic tendency and depression. Stress has positive regulating effect to pessimistic tendency and depression. The higher the stress is, the bigger negative effect of optimistic tendency to depression is. That is to say, the lower the optimistic tendency is, the higher the depression is. The higher the stress is, the bigger positive effect of pessimistic tendency to depression is. That is to say, the higher the pessimistic tendency is, the higher the depression is. Stress has positive regulating effect to pessimistic tendency and anxiety. The higher the stress is, the bigger positive effect of pessimistic tendency to anxiety is. That is to say, the higher the pessimistic tendency is, the higher the anxiety is.Stress has some regulating effect to self-efficacy optimism and life satisfaction. The higher the stress is, the bigger negative effect of self-efficacy optimism to life satisfaction is. That is to say, the higher the self-efficacy optimism is, the higher the life satisfaction is. Stress has some regulating effect to pessimistic tendency and positive moods. The higher the stress is, the bigger negative effect of pessimistic tendency to positive moods is. That is to say, the higher the pessimistic tendency is, the lower the positive moods are.
