In the present study, a model of relations is tested between the dimensions of socialization, personal resources such as optimism and self-efficacy, and the resources obtained during integration into the organization such as social support or collective efficacy in the prediction of the attitudes and behaviors of the Spanish National Police. Participants were members of the Spanish National Police (N = 123). The findings confirm some of the hypotheses, although other findings are contrary to the predictions. The percentage of variance explained in the regression analyses varies between 48% of the variance of stress and 24% of the variance of task commitment. The findings open new lines of research for the future given the positive impact of human resource management on satisfaction and commitment at work, as well as job stress and excellent performance.
