Parental competence is one of the essential components of raising ethical and healthy children. The mother's satisfaction with her maternal role significantly influences her cognitive responses and parenting behaviors. Having appropriate instruments to measure maternal satisfaction and identify and solve potential problems after childbirth can substantially contribute to maintaining and improving mother and infant health. This study aimed to evaluate the psychometric properties of the Parenting Sense of Competence (PSOC) Scale in mothers referring to the healthcare centers affiliated with Qazvin University of Medical Sciences. This cross-sectional psychometric study collected data from 254 mothers with 1.5-month-old infants referred to the healthcare centers in Qazvin Province. Data were analyzed using the item response theory (IRT) in SPSS 26 and Stata 17 software. The mean age (±standard deviation) of participants was 30.05 ± 5.7, and the overall Cronbach's alpha for the scale was 0.931. We used the graded response model (GRM) appropriate for Likert-type rating scales to fit the IRT. The discrimination parameter estimates showed that item 5 had a discrimination level <0.65, leading to its exclusion from the final analysis. In addition, the total information index confirmed that the scale was suitable in the trait range of -2.1 to 1.8. Compared with other common models for ordered responses based on general model fit indices, the GRM showed a better fit. The study results recommend applying the IRT models to improve and enhance the quality of questionnaires in various measurement fields.
父母育儿能力是培养有道德、健康孩子的重要组成部分之一。母亲对其母亲角色的满意度会显著影响她的认知反应和育儿行为。拥有合适的工具来衡量母亲的满意度，并识别和解决产后潜在问题，对于维持和改善母婴健康有很大帮助。本研究旨在评估在加兹温医科大学附属医疗中心就诊的母亲中，育儿胜任感（PSOC）量表的心理测量特性。这项横断面心理测量研究收集了254名有1.5个月大婴儿且在加兹温省医疗中心就诊的母亲的数据。使用SPSS 26和Stata 17软件中的项目反应理论（IRT）对数据进行分析。参与者的平均年龄（±标准差）为30.05±5.7，该量表的总体克朗巴哈系数为0.931。我们使用适合李克特式评分量表的等级反应模型（GRM）来拟合IRT。区分参数估计显示，第5项的区分度水平<0.65，因此在最终分析中将其排除。此外，总信息指数证实该量表在-2.1至1.8的特质范围内是合适的。与基于一般模型拟合指数的其他常见有序反应模型相比，GRM显示出更好的拟合度。研究结果建议应用IRT模型来改进和提高各个测量领域问卷的质量。
