| Background:The rapid development of China social economy has been able to meet the people’s demand for food and clothing.However,the Chinese people demand for the quality of life has put forward a higher level.With the rapid transformation of social lifestyle and the improvement of working rhythm,adults in Chinese mainland are under pressure from various aspects such as society,work and family.The emergence of social capital provides a new direction and idea for us to solve the problem of low life satisfaction in our country.Aims:The main purpose of this study is to understand the current level of life satisfaction of Chinese adult residents,analyze the main factors affecting life satisfaction and confirm the relationship between cognitive social capital and life satisfaction.On this basis,we further verify whether depressive symptoms play a mediating role between cognitive social capital and life satisfaction.Methods:This study uses the personal level questionnaire data in the 2016 China family panel studies(CFPS)project,and selects Chinese adult residents over the age of 16 as the research object.The questionnaire uses a multi-stage unequal probability system cluster sampling(PPS)method.After excluding individuals who lack key information and do not meet the requirements of this study,a total of 28018 respondents were included.In this study,we used SPSS 24.0 to clean and sort out the data.Firstly,categorical variables and continuous variables were described by constituent ratio(%)and mean±standard deviation((?)±s)respectively.Secondly,theX~2test and t test were used to explore whether the effects of general characteristic variable,socio-economic status,depressive symptoms and cognitive social capital on life satisfaction were statistically significant.Furthermore,binary logistic regression was used to complete the multivariate analysis of life satisfaction among Chinese adults.Then,we used pearson correlation analysis to analyze the relationship between cognitive social capital and depressive symptoms.Finally,we used process to confirm whether depressive symptoms have a mediating role between cognitive social capital and life satisfaction.Results:1.In 2016,the life satisfaction rate of adult residents in China is 54.2%.2.In terms of gender,the proportion of women who think they are satisfied with life(55.9%)is higher than men(52.5%).In terms of age distribution,>65 years old is the highest proportion of life satisfaction among adult residents in China(68.7%),and the lowest proportion is 26-35 years old(46.1%).The life satisfaction rate of residents with non-agricultural household registration(56.1%)was higher than that of residents with agricultural household registration(53.4%).With regard to marriage,unmarried residents had the highest proportion of life satisfaction,accounting for 56.0%.The residents who think they are in better health have a higher proportion of life satisfaction,and the proportion of life satisfaction of residents who think they are healthy is 57.7%.Among the high self-rated income level and high self-rated social status,the proportion of life satisfaction is the highest,accounting for 81.5%and 78.8%respectively.3.Through binary logistic regression analysis,it is found that the probability of life satisfaction of female residents is higher than that of male residents(OR=1.292;95%CI=1.222-1.365).The relationship between age and life satisfaction was U-shaped,and residents aged 26-35 had the lowest probability of life satisfaction(OR=0.657;95%CI=0.582-0.742),residents aged>65 had the highest probability of life satisfaction(OR=1.377;95%CI=1.180-1.606).Life satisfaction was higher among non-agricultural residents(OR=1.091;95%CI=1.081-1.170).The life satisfaction of non-agricultural workers was higher than that of agricultural workers(OR=1.112;95%CI=1.035-1.194).The life satisfaction of residents with good self-rated health status was higher than unhealthy residents(OR=1.274;95%CI=1.168-1.391).The probability of life satisfaction decreased by 0.949 times for each point of depressive symptoms.From the perspective of residents’socio-economic status,residents’self-rated income level and self-rated social status are positively correlated with life satisfaction.Cognitive social capital is significantly correlated with life satisfaction.For every increase in the trust,neighborhood relationship and sense of belonging,the probability of life satisfaction increases by 1.031,1.153 and 1.190 times respectively.Compared with residents who have never experienced injustice,the probability of life satisfaction of residents with at least one injustice is reduced to 0.851.4.The cognitive social capital have a significant predictive effect on depressive symptoms.Trust,neighborhood relationship,reciprocity and sense of belonging were negatively correlated with depressive symptoms,with correlation coefficients of-0.172,-0.155,-0.153 and-0.144 respectively(P<0.01).Injustice was positively correlated with depressive symptoms(r=0.242,P<0.01).5.The results of the mediation analysis showed that depression symptoms have a significant intermediary effect between the indicators of cognitive social capital and life satisfaction.The direct effects of trust,injustice,reciprocity,neighborhood relationship and sense of belonging on life satisfaction were 0.187,-0.085,0.093,0.134 and 0.151respectively.The mediating effects of depression on trust,injustice,reciprocity,neighborhood relationship,sense of belonging and life satisfaction were 0.044,-0.065,0.042,0.042 and 0.039,respectively.Conclusion:1.In 2016,more than half of adult residents in China were satisfied with their life.2.There are differences in life satisfaction of Chinese residents with different gender,age,marital status,household registration,job type and self-rated health.3.The distribution of life satisfaction of Chinese adult residents with different years of education,self-rated income level and self-rated social status is different.4.There is a significant correlation between cognitive social capital,depressive symptoms and life satisfaction.5.Depressive symptoms have a partial mediating effect between cognitive social capital and life satisfaction. |
