This study examined the relationship between child caregiver commitment and the caregiver's personal characteristics and work experience, the characteristics of the job, and the quality of the child care center. Questionnaires that included several measurement instruments were sent to 381 full-time child caregivers in 94 centers. Caregiver commitment was measured by means of the Organizational Commitment Questionnaire; job satisfaction was measured by the Job Descriptive Index; and job characteristics were measured by the Job Diagnostic Survey. Center quality was assessed by an analysis of four factors: staff-child ratio; amount of caregiver training; group size; and staff turnover. Results indicated that the most powerful predictor of caregiver commitment was the caregiver's job satisfaction. A relationship to commitment was also found for the caregiver's perception of job characteristics, the caregiver's age, and the caregiver's education. A relationship to commitment was not found for center quality, caregiver wages, and caregiver tenure. A 44-item bibliography is included. (BC)
