Construct validity and internal consistency of the Home and Family Work Roles Questionnaires: a cross-sectional study with exploratory factor analysis.

INTRODUCTION

Exploratory Factor Analysis (EFA) measures the underlying relationships between questionnaire items and the factors ("constructs") measured by a questionnaire. The Home and Family Work Roles Questionnaire has not been assessed using EFA; therefore, our objective was to identify the factors measured by this questionnaire.

METHODS

We recruited 314 persons to complete the questionnaire and to answer several demographic questions. We determined if the data was factorable by performing Bartlett's test of sphericity and the Kaiser-Meyer-Olkin measure of sampling adequacy. We used the Factor package in Jamovi statistical software to perform EFA. We employed an Oblimin rotation and a Principal Axis extraction method. We also calculated the internal consistency of the questionnaire as a whole as well as each individual question.

RESULTS

Our sample consisted of 265 (85%) women, 45 (14%) men, and 3 (1%) non-binary or other genders. The mean age of our participants was 34.65 (SD = 11.57, range = 18-65) years. EFA suggested a three-factor model. Questions 11, 13, 14, 15, and 16 measured one factor (we interpreted this as "Caregiving Roles"), questions 1, 3, 4, 8, 9, 10, 18, and 19 measured a different factor ("Traditionally Feminine Roles"), and questions 2, 5, 6, and 12 measured the "Traditionally Masculine Roles". The questionnaire and each individual question demonstrated excellent internal consistency (Cronbach's α > 0.90).

CONCLUSION

The Home and Family Work Roles Questionnaire may measure three distinct factors, which we have named Caregiving, Traditionally Feminine, and Traditionally Masculine Roles. This aligns with the theory used in developing the questionnaire. Separation of the Home and Family Work Roles Questionnaire into three sub-scales with distinct scores is recommended to measure each of the recommended constructs.
