乐观对大学生健康状况的影响及作用机制

The Influence and Mechanism of Optimism on College Students’ Health

目的:探讨乐观、健康相关行为、疾病易感性、抑郁对大学生健康状况的影响及作用机制。方法:使用青少年乐观问卷、健康相关行为问卷、抑郁问卷、疾病易感性问卷、健康状况问卷对1316名大学生进行施测,使用LISREL8.7建立结构方程模型,检验乐观、健康相关行为、疾病易感性、抑郁与大学生健康状况的关系。结果:(1)乐观对健康状况没有直接的效应,乐观是通过抑郁、疾病易感性、促进健康行为、危害健康行为的完全中介对健康状况产生间接的影响;(2)疾病易感性、危害健康行为直接负向预测健康状况;(3)促进健康行为直接正向预测健康状况,危害健康行为负向预测健康状况;(4)乐观负向预测抑郁,抑郁正向预测疾病易感性。结论:抑郁、疾病易感性、促进健康行为、危害健康行为对大学生健康状况有重要影响,乐观是通过抑郁、疾病易感性、促进健康行为、危害健康行为的完全中介对健康状况产生间接的影响。

The purpose of this research is to explore the influence and mechanism of 4 objects namely optimism, health-related behavior, disease susceptibility, and depression on the health of college students. And 1316 college students were tested with questionnaires designed each on these objects. The structural equation model was established with LISREL8.7 to test their relationships. The findings are as follows: 1) optimism has no direct effect on health status;its indirect influence is made through the complete intermediary of depression, disease susceptibility, behaviors either promoting or damaging health;2) through disease susceptibility and health damaging behavior can be predicted health directly and negatively;3) through health promoting behavior, health can be predicted directly and positively, and vise versa. 4) optimism negative helps predict depression, and depression positive disease susceptibility. Here comes the conclusion: all 4 objects selected have important influence on the health of college students, and the first finding of the research is verified.
