“…The benchmark regression results suggested that people with religious beliefs had higher levels of depression in China, which was also partially supported by the relevant literature (63,64). But by taking empirical measurements and/or conducting metaanalyses using different measurement scales, samples, databases, and taking data from different countries, religious beliefs, and nations, most related studies had found that religious beliefs and participation in religious behaviors could improve happiness, subjective well-being, and mental health (65)(66)(67)(68)(69)(70)(71)(72)(73). For example, Cohen-Zada and Sander (68) used repeal as an instrumental variable for church attendance and provided direct evidence that church attendance had a significant positive effect on happiness; the study of Kortt et al (66) provided strong evidence of an association between attendance at religious services and life satisfaction in the Australian social context; Van Cappellen et al (71) found that religious beliefs could increase happiness through positive emotions of self-transcendence.…”
