摘要:Objectives This study aimed to develop and validate the Maternal Overprotection Scale to measure the degree of maternal overprotective behaviors in child-rearing. Methods There were two parts in this study. In Study 1, the items and scale development was conducted and in Study 2, the scale evaluation was conducted. In Study 1, the sample consisted of 262 mothers with young children aged from five to six years. Mothers rated themselves on the degree of their overprotecting behaviors carried toward their children. The scale initially comprised 45 items, and it ended up with 18 items based on exploratory factor analysis and exploratory structural equation modeling. In Study 2, the data of additional 197 mothers who responded to these items were analyzed by means of confirmatory factor analysis and correlation analysis. Results In Study 1, the exploratory factor analysis and exploratory structural equation modeling of the scale identified three sub-scale factors: Intrusive Control (eight items), Permissive Indulgence (four items), and Anxious Protection (six items). In Study 2, the Cronbach’s α values ranged from .70 to .85, showing appropriate levels of internal consistency. The cross-validation was established using different samples. The concurrent validity was confirmed by the association with a maternal parenting attitude measured by the Parenting Dimensions Questionnaire (PBDQ). Conclusion The Maternal Overprotection Scale reliably and accurately measured degrees of overprotective maternal parenting with young children. This scale can be used as a tool for estimating individual differences in mothers’ overprotection for their young children, as well as correlations with other aspects of development.
