The Parent Overprotection Measure (POM) is a promising scale to measure parent overprotection toward a child from the parent's perspective. However, no Japanese translation of the scale has been developed, and whether the POM can be applied to a Japanese population is unknown. This study translated the POM into Japanese and examined its psychometric properties. Parents of 380 children aged 4 to 7 years (including 190 mothers and 190 fathers) completed online questionnaires. Exploratory and confirmatory factor analyses (CFA) indicated that the Japanese translation of the POM has a bi-factor structure, including one general factor (general overprotection) and two specific factors (care/attention and control/prevention). The measurement invariance of reports from mothers' and fathers' perspectives was confirmed by multiple group CFA. The McDonald's Omega was acceptable for all factors, but the general overprotection factor explained most scale variance. Pearson's correlation coefficients were more than .20 between the control/prevention factor and child anxiety symptoms in both mother and father reports. The correlation between the control/prevention factor and parent anxiety according to fathers' reports also exceeded .20. These results provided the factor structure and supported the reliability of the POM among a Japanese population; however, further investigation of the validity of the scale is needed.
