Meta-analysis of Studies Conducted on the Relationship between security feelings and Social Health

The present study is aimed at using meta- analysis method to analyze and combine the results of previous studies conducted on the relationship between security feeling and social health.

The statistical population of this study consisted of all studies conducted in the years 2010 to 2020. Finally 22 studies that had the appropriate characteristics to enter the meta-analysis were selected via referring to and searching in internal sites and through targeted sampling. In order to analyze the information, the second version of the comprehensive meta-analysis software (CMA2) was used and due to the heterogeneity of the studies, the stochastic impacts model was used to combine the results and achieve the impact size.

In the first step of evaluation of selected researches, homogeneity and publication error assumptions were examined, and the relevant findings indicated heterogeneity of the size of the work and also showed the studies were not biased. In the second stage, the impact size coefficient and the moderating role of the variables in terms of geographical dispersion of the studies were evaluated. The results of the studies indicated that the magnitude of the impact or coefficient of impact of the social security feeling on social health is (0.409), which is assessed to be a moderate impact according to Cohen's interpretive system. In order to examine source of heterogeneity, the modifier variable of “geographical dispersion" has been used. The results showed that the calculation of the impact size varies based on the geographical dispersion between different regions. For instance, the combined effect size of the east and west are (0.195) and (0.270) which is considered weak according to Cohen's interpretive system. In other words, choosing provinces or cities in these areas significantly reduces the relationship between security feeling and social health.
