This study examined how motivations and justice perceptions affect volunteer’s psychological attachment to their voluntary organization. Samples were drawn from volunteers serving in an international humanitarian and non-governmental organization. A survey questionnaire was developed to collect data on the demographics and the study variables of organizational justices, volunteer motivations and affective commitment. A total of 432 valid questionnaires were received and analyzed. Hierarchical regression was adopted to test hypotheses, which found support for the relationship between intrinsic motivation and affective commitment, and partial support for the relationship between certain types of extrinsic motivations (self-esteem and understanding) and affective commitment. In addition, some forms of perceived organizational justices (distributive, procedural, and interactional justice) have a significant but partial moderating effect on the relationship between types of motivation (intrinsic, self-esteem, and understanding) and affective commitment. Implications for the relationship between perceived organizational justices, types of motivation, and affective commitment were discussed.
