The Effect of Attitudinal and Behavioral Commitment on the Internal Assessment of Organizational Effectiveness: A Multilevel Analysis

Using a multilevel analysis including 207 volunteers and paid workers nested within 51 nonprofit organizations (NPOs), this study examines the effect of individual and group attitudinal and behavioral commitment on their assessment of organizational effectiveness. Drawing on classical attitude theories, our results indicate that individuals with higher affective organizational commitment tend to assess their NPO’s effectiveness higher, while individuals staying because of the lack of alternatives assess it lower. However, in line with behavioral commitment theories, both relationships are mediated by the effect of teamwork behavioral commitment. We also found a negative effect of normative attitudinal commitment partially nested at the group level. Overall, our results suggest that encouraging volunteers and paid workers to participate in concrete teamwork behaviors on a daily basis constitutes a twofold benefit: it adds to the effect of affective attitudinal commitment at the individual level, while counter balancing the negative effects related to normative individual and collective resistances.
