<![CDATA[Introduction: This study aimed to conduct an initial psychometric evaluation of knowledge and attitude instruments, modified from existing validated community-based Nurturing Care instruments, measuring maternal knowledge and attitudes Methods: A methodological study with a cross-sectional psychometric validation design was conducted in three consecutive phases: (1) modifications of the instrument and content validation, (2) construct validation, and (3) assessment of reliability. A total of 105 mothers of children aged 6–59 months were recruited from the tertiary pediatric ward in Yogyakarta, Indonesia. To evaluate content validity, the Item-level Content Validity Index (I-CVI) and Content Validity Ratio (CVR) were computed. Knowledge items were evaluated for item discrimination using point-biserial correlation, and the attitude construct was evaluated using Confirmatory Factor Analysis (CFA) under a four-factor model. Results: The tools demonstrated excellent content validity (I-CVI = 1.00, CVR = 1.00, and S-CVI/Ave = 1.00). The knowledge instrument comprised 16 items and demonstrated adequate item-level discrimination, with 14 of the 16 items showing point-biserial correlations (rpb = 0.319–0.547) and a KR-20 of 0.646. The attitude instrument comprised 20 items and, following model revision, showed partial support for the hypothesized four-factor structure (χ²/df = 1.867, SRMR = 0.048, CFI = 0.874, TLI = 0.837, RMSEA = 0.091), with excellent internal consistency (Cronbach's alpha = 0.885). Conclusions: The instruments provide preliminary psychometric evidence to address an important measurement gap in pediatric nursing regarding maternal knowledge and attitudes towards Nurturing Care during child hospitalization, and they require further validation in larger and more diverse samples.]]>
