Validation of the military organization socialization inventory (MOSI)

Organizational socialization is pivotal in military contexts due to the unique demands and hierarchical structures of these institutions. This study aimed to adapt and validate the Military Organizational Socialization Inventory (MOSI), a tool designed to assess the degree of socialization among military personnel by evaluating whether individuals perceive themselves as newcomers, full members, or marginal members. A sample of 563 cadets from the Italian Army Non-Commissioned Officers School participated in the study. Participants completed the MOSI alongside established measures such as the Content Areas of Socialization Scale (CAS), the Organizational Socialization Inventory (OSI), and the Affective, Continuance, and Normative Commitment Scales. Confirmatory Factor Analysis (CFA) supported a three-factor structure consistent with theoretical models, though initial fit indices indicated potential for refinement. A second-order factor model demonstrated improved fit, reinforcing the multidimensional nature of organizational socialization in military settings. The MOSI showed strong convergent validity through significant correlations with the CAS and OSI, and predictive validity was supported by meaningful relationships with commitment scales. Limitations include the cross-sectional design and data collection within a single military context, which may limit generalizability. Future research should employ longitudinal designs, explore different military branches, and consider cultural contexts to further validate the MOSI. Additionally, examining variations in personnel roles and deployments could provide insights into how these factors influence socialization levels. Overall, MOSI offers a reliable and valid tool for assessing organizational socialization in military environments, with implications for enhancing integration processes and organizational effectiveness.
