This study explores the multi-dimensionality of organizational commitment of volunteer chamber of commerce board members using the Meyer and Allen (1997) scale. The effect of organizational commitment on desirable board member roles is also tested. Theory is developed by uniting past research in both organizational commitment and employee motivation. A proposed scale is tested using Confirmatory Factor Analysis with data gathered from 616 respondents at 116 chambers of commerce in 36 states. Structural Equations Modeling is then used to examine the effects of organizational commitment on several critical roles the board member is hoped to perform. Unlike prior research using Meyer and Allen's (1997) scale that focused on paid employees, our results indicate that normative, affective, and continuance commitment based on low alternatives are the three distinct constructs applicable to volunteer employees. Moreover, these components have a positive effect on board member's roles.
