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.
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.
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).
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.
探索性因素分析（EFA）衡量问卷项目与问卷所测“构念”（即“因素”）之间的潜在关系。家庭和工作角色问卷尚未采用 EFA 进行评估；因此，我们的目的是确定该问卷所测的因素。
我们招募了 314 人来完成问卷并回答几个人口统计学问题。我们通过进行巴特利特球形检验和凯泽-迈耶-奥尔金抽样充分性度量来确定数据是否可进行因子分析。我们使用 Jamovi 统计软件中的 Factor 包进行 EFA。我们采用斜交旋转和主成分提取方法。我们还计算了问卷整体以及每个问题的内部一致性。
我们的样本由 265 名（85%）女性、45 名（14%）男性和 3 名（1%）非二元性别或其他性别组成。参与者的平均年龄为 34.65 岁（标准差=11.57，范围=18-65 岁）。EFA 提示存在一个三因素模型。问题 11、13、14、15 和 16 测量一个因素（我们将其解释为“照顾角色”），问题 1、3、4、8、9、10、18 和 19 测量另一个因素（“传统女性角色”），问题 2、5、6 和 12 测量“传统男性角色”。问卷和每个问题都表现出极好的内部一致性（Cronbach's α>0.90）。
家庭和工作角色问卷可能测量三个不同的因素，我们将其命名为照顾角色、传统女性角色和传统男性角色。这与开发问卷时所采用的理论相符。建议将家庭和工作角色问卷分为三个具有不同得分的子量表，以分别测量每个推荐的构念。
