The purpose of the present study was don meta-study about research done in relation to the theft during the years 85 to 96 in Tehran metropolis. 10 studies were identified in the field the occurrence of theft. The results part of the meta-theory and meta-method showed that the researches carried out on the subject of the research except in cases (the analytical model extracted from the theoretical framework and basics review, preliminary test of measuring instrument, operational definition, assess reliability and validity, the mention of research limitations and barriers and ethical considerations) are at a rather favorable level and also, the results of meta-analysis showed that the combined effect size index in the field of factors affecting of theft in the fixed model is 0.438 and randomized model 0.414,which according to Cohen's criterion, had a large amount of effect size. But in a separate survey, in the area of effective factors in the occurrence of theft effect size of individual factors was more than family and cultural-social factors. Results demonstrated that the publication bias in meta-analysis sample. Due to the heterogeneity in the studies, the moderators were analyzed which showed the moderating effect of the year and the sampling method.

In the last decade, Iranian researchers in the field of sociology and management have widely used the grounded theory in their research. Given the specific features of this methodology, the main issue of the present study is that what are the strengths and weaknesses of sociological and managerial research based on grounded theory? To answer the research question the meta-method and the systematic review were used. The studied population consists of a series of articles published in international scientific journals from 2016 to 2018 that due to the focus of the research on critical methodology of grounded theory based on the approach of Strauss and Corbin, 36 articles were selected and reviewed in the source selection stage. the results of the research indicate that the researches face with fundamental problems about the criteria of “problem, the formulation of micro questions, the studied population, the explanation of the stages of data analysis in the findings select, the coincidence of data collection and analysis, category building technique, category dimensional recognition technique, named selection technique, core category selection technique, credibility, comparison with other theories and theoretical sensitivity”. These problems can be categorized into five categories of technical challenges, the theory and method gap, the distortion of the goal, the lack of knowledge of grounded theory and the paradigmatic challenge.
