A scale of parent-to-child emotions: Adaptation, factor structure, and measurement invariance

Emotions that parents feel when they think about their own child are extremely important in determining parenting approaches toward a child. Parental emotions should be defined under the rubric of human emotions that include both basic and self-conscious emotions. The Scale for Parent-to-Baby Emotions (SPBE) was developed underlying this concept, whereas an applicable scale for parent-to-child emotions for a wider age range for both mothers and fathers is needed. This study is aimed at examining the measurement invariance of this adapted scale among Japanese families. In a cross-sectional internet survey, men and women who had a child/children (including a fetus), whose eldest was aged up to 12 years old (N = 4600), were recruited. The questionnaire, which included the Scale for Parent-to-Child-Emotions-62 (SPCE-62) created from the SPBE via a process of rigorous translation, focused only on the eldest child. The feasibility of the SPCE-62 was assessed by a panel of three researchers. Each domain of both basic and self-conscious emotions was examined both in terms of robust factor structure and stable measurement invariance by multi-group confirmatory factor analysis. Responses to individual items were examined via item response theory, including differential item functioning. This resulted in a 43-item SPCE consisting of 9 domains: Happiness (four items), Anger (six items), Fear (four items), Sadness (five items), Disgust (five items), Shame (five items), Guilt (seven items), Alpha Pride (three items), and Beta Pride (four items). An empirical construct of parental emotion toward a child was derived. The SPCE makes it possible to measure parent-to-child emotions across parents' gender and the three age ranges of the child.
