Purpose: To establish content validity of the ESBQ to measure employers' intention to support breastfeeding mother. Many mothers have difficulty sustaining breastfeeding after returning to work. The ESBQ was developed to measure employers' intention and influencing factors to support breastfeeding in working mothers. The 77 item ESBQ has eight subscales including: intention, attitudes, behavioral beliefs, outcome evaluation, overall subjective norms, normative belief, motivation to comply, and perceived behavioral control. Psychometric testing of the ESBQ was needed. Theoretical/conceptual framework: The theory of planned behavior (Ajzen, 1991) provided the theoretical framework for ESBQ development. Subjects: Three experts in the theory of planned behavior have worked with breastfeeding mothers. Methods: To establish content validity, a two-stage content validity process outlined by Lynn (1986) was applied: the Developmental Stage and Judgment-Quantification Stage. Three experts were asked to first, identify content domain and second, rate the content relevance of the items using a 4-point rating scale from 1 to 4 (1 - not relevant; 4 very relevant). The proportion of agreement among judges, content validity index (CVI) and scale-level index (S-CVI) showing the proportion of agreement among judges were calculated. Results: Thirty-one items with CVI of less than 0.66 were deleted. A total of 46 items of the ESBQ with 8 subscales were retained with CVI ranging from 0.85-1.00 and the overall CVI was .92. All experts agreed that the ESBQ will be useful for assessing employers' attention to support breastfeeding in working mothers. Conclusion: Overall content validity of the ESBQ was high. All eight ESBQ subscales revealed excellent CVI. Findings suggest the instrument can effectively assess and evaluate employers' support for breastfeeding in the workplace. However, further validation and reliability testing are needed.
