Abstract
The purpose of this study is to explore the impact of involvement, constraints, benefits and commitment on career volunteers' engagement in serious leisure. The questionnaire was adopted as the research instrument and administered in Bliss and Wisdom Educational Park. 219 copies were collected as major data. The data were analyzed in One-Way ANOVA, Scheffe, and LISREL to investigate the logic relationship between the variables. The major findings of this study are summarized as the following. 1. Life value is the most important concern which influences career volunteers' involvement in serious leisure. Interpersonal relationship is the most frequently mentioned constraint for career volunteers' serious leisure. Religion is ranked the highest as career volunteer's belief in serious leisure. Emotional indulgence is the foremost commitment of career volunteers to serious leisure. 2. Involvement has negative influence on constraints. Involvement positively affects benefits. Constraints produce negative influence upon beliefs. Benefits lead to positive influence upon commitments. Constraints have negative influence upon commitments. Involvement generates positive influence upon commitments. 3. Life value, degree of importance, and core life are three positive indicators of involvement in serious leisure. Three most obvious indicators of restricting serious leisure are personal, interpersonal, and structural constraints. Religious blessing, physical health, social opportunity, and development of potential energy are four positive benefits of serious leisure. Emotional indulgence and behavioral accordance positively influence one's commitment to serious leisure.
