Purpose: Organizational and administrative destructive behaviors cause many direct and indirect costs on organizations and reduce organizational progress. Therefore, the objective of this study was to identify antecedents of destructive organizational and administrative behaviors based on social exchange theory by meta-synthesis method. Methodology: This study was developmental in terms of objective, cross-sectional in terms of time, and qualitative in terms of data collection. The field of research included 582 articles on destructive organizational and administrative behaviors during 2000-2022. The research sample included 55 articles selected by purposive sampling method and according to inclusion criteria. The data were collected by note-taking (validity was confirmed by the triangulation method and reliability was estimated to be 0.89 by the Cohen's kappa coefficient) and analyzed by content analysis using the seven-step meta-synthesis method of Sandelowski and Barroso (2007). Findings: The results showed that the antecedents of destructive organizational and administrative behaviors based on social exchange theory had two main categories and six subcategories. Each of the two categories of facilitating antecedents and inhibiting antecedents included three subcategories of behavioral factors, structural factors, and contextual factors. Finally, given the categories and subcategories, a model of the antecedents of destructive organizational and administrative behaviors based on social exchange theory was drawn. Conclusion: The model of antecedents of organizational and administrative destructive behaviors based on social exchange theory designed in the present study can be used as a tool for strategic planning in the field of organizational and administrative destructive behaviors.

Given that social institutions are the basis of any society, they must ideally operate in unison with functional necessities for any society to function and then flourish. The plethora of issues confronting Nigeria as a country may be traced back to weak, incompetent, and dysfunctional social institutions that have failed to alter the status quo. According to Talcott Parsons, society is analogous to the human body, and in order for the body to thrive, all of its elements must collaborate. For Nigeria to advance, all social institutions, including family, school, religion, politics, and the economy, must work together to create repeatable results. It is against this background that this paper sought to examine the role of family structure in Nigeria and their pro-activeness in propelling national development. Literature was extensively reviewed from relevant publications and journals and it revealed that the family structure in Nigeria is gradually becoming weak and dysfunctional. This is attributed to a lot of changes that are taking place in the institution of family which quite often poses a threat to the very survival of family system universally. It was then concluded that there is need for every family to hold with uttermost importance the place or morals, socialization and regulation of individual member of the family’s behaviour.
