Explaining the impact of social capital on crime tendency:Meta-analysis of researches

The main purpose of the research is to evaluate the impact of social capital on the tendency to commit crime (research articles published in the authoritative scientific quarterly). The research method is meta-analysis (quantitative software for combining the effect sizes of independent and dependent variables), the sample size is 16 research documents, the analysis unit of articles in the time period of 2005 to 2022 is a deliberate (non-probability) sampling method. After identifying the value of the correlation coefficient, sample size and significance level (provided it is significant), the year and the authors of the research, they were entered into the cma2 program and while estimating the effect of individual studies, the overall effect size.The results show that social capital has an inverse and significant relationship with crime tendency. The components of social capital show that social trust with a value of 49%; religious affiliation (33 percent); Social support (36 percent) has the highest impact; social cohesion (29 percent); Local participation (23%) has a moderate effect and environmental belonging has the least effect with a value of 19%. The above results show that a total of 16 above researches have been able to explain 0.37 (random) of the changes in crime tendency through social capital, as much as one change in the amount of social capital, 3 tenths of the changes in the crime tendency occur and with its increase, the probability of committing a crime decreases among the investigated groups. Tendency to crime among students (0.586) is more affected by the amount of social capital than all groups. Tendency to crime among men (0.39) is more than women (33%) and physically; Physically and psychologically, men have a greater tendency to commit crimes compared to women. There is a significant relationship between the level of development of the province and tendency to crime, and its value is equal to 11%. Meanwhile, the amount of tendency to commit crime is higher in developed provinces (30%) and less in developing (21%), medium and low-developed provinces (14%).
