Cheng and other researchers analyzed the influence of social support on college students' mental health, and specifically discussed the role of social support on various components of mental health. The results show that the most obvious influence on mental health is objective support and support utilization. In addition to the general population, there are also studies on poor college students, and it is found that in the intermediary model between parents' parenting style and mental health of poor college students, the reverse prediction of social support on mental health has reached a significant level. In addition, in the study of prisoners, Jin Haifeng and others found that social support of prisoners has a significant predictive effect on mental health. Further analysis shows that Q4, O and coping style factors in prisoners' cartel personality play a completely mediating role in the model of social support affecting mental health. In other words, for prisoners, the influence of social support on mental health is produced directly or indirectly through personality and coping style. In the discussion of the relationship between social support and mental health, most researchers have basically reached the same conclusion through questionnaires, that is, adequate social support has a significant positive effect on mental health, which is consistent with most groups. However, this positive effect is not directly produced by social support, but also closely related to other internal factors such as individual personality traits and coping styles.
Second, social support and subjective well-being
Subjective well-being is an individual's subjective feeling of his quality of life according to his own standards, and it is also an important standard of individual mental health. Therefore, many researchers have discussed the influence of individual social support system on individual mental health from the perspective of subjective well-being. Zhang et al.' s research introduced emotional intelligence factors, and the results showed that subjective well-being was significantly related to social support and emotional intelligence. For individuals with high EQ, they can better comprehend and understand the emotions of themselves and others. When they have enough social support, they can also make full use of this condition, thus affecting their subjective well-being. For individuals with low EQ, even with sufficient social support, it is difficult to improve their subjective well-being. In this mechanism, the effect of social support on mental health is mainly through improving the general gain of subjective well-being, which also needs the synergy of individual internal factors. Wu Guoqiang and others found that life events and social support can predict subjective well-being. In addition, social support plays a complete intermediary role between life events and subjective well-being, while coping styles play a partial intermediary role. In other words, life events will affect individuals' positive and happy feelings, but social support can alleviate the negative impact of such stress events, which verifies the buffering effect of social support. At the same time, coping style also plays a role in this influence path, that is, life events indirectly affect coping style through social support and then affect subjective well-being.
Third, social support and pressure.
Other researchers have investigated the buffering effect of social support on mental health from the perspective of stress. Life events are an important cause of all kinds of negative emotions. Most scholars believe that social support plays an important role in relieving individual pressure, that is, individuals with good social support systems can better adapt to changes in life. Social support can not only directly affect bad psychological symptoms, but also indirectly buffer between life events and psychological symptoms. Taking college students as subjects, Tu Yangjun found that individual social support, especially subjective support, plays an important role in negative emotions caused by life events. Wu Xinchun and others investigated the relationship between post-traumatic stress disorder and social support of local primary school students six months and one and a half years after Ya 'an earthquake. It is found that the degree of personal trauma exposure and subjective fear have a significant positive predictive effect on post-traumatic stress disorder, but social support can significantly alleviate post-traumatic stress disorder. Especially in a year and a half after the disaster, social support can significantly buffer the influence of subjective fear on post-traumatic stress disorder. The above research shows that the effect of social support on mental health is not only direct, but also indirect through internal factors such as individual characteristics and coping styles. At the same time, social support not only improves subjective well-being and mental health through universal access, but also reduces the adverse psychological impact brought by life events or stress events through buffering.
