The Influence Of Maternal Knowledge Determinants According to The Theory of Reasoned Action on Adherence to Neonatal Congenital Hypothyroidism Screening
Abstract
Congenital hypothyroidism screening (CHS) is a crucial effort to detect thyroid disorders in newborns to prevent growth and developmental delays. This study aimed to analyze the influence of maternal knowledge determinants based on the Theory of Reasoned Action on adherence to congenital hypothyroidism screening among newborns in the working area of the Buleleng I Public Health Center, Buleleng Regency, in 2025. A cross-sectional design, involving 50 postpartum woman selected through purposive sampling. Data were collected using a questionnaire and was tested bivariately using Fisher exact test. The study was conducted from January to February 2025. Fisher's Exact test indicated that variables significantly associated with CHS adherence were parity (p=0.048; OR=5.17; 95% CI=1.19-22.39), maternal age (p=0.012; OR=7.07; 95% CI=1.57–31.85), maternal education (p=0.002; OR=0.1; 95% CI=0.16-0.63), maternal occupation (p=0.009; OR=9.33; 95% CI=1.72–50.61), source of CHS information (p=0.018; OR=7; 95% CI=1.48-33.1), and family support (p=0.000; OR=27.00; 95% CI=3.03–240.39). Additionally, components of the Theory of Reasoned Action, including attitude toward behavior (p=0.007; OR=8.50; 95% CI=1.83-39.42), subjective norm (p=0.000; OR=27.00; 95% CI=3.03–240.39), and behavioral intention (p=0.004; OR=9.33; 95% CI=1.96-44.36), also showed significant influence. Knowledge determinants and reasoned action theory can be used as measuring tools for maternal compliance in carrying out congenital hypothyroid screening in newborns.
