ObjectiveTo identify geographic, sociodemographic, and clinical factors associated with parental self‐efficacy in a diverse cohort of deaf or hard‐of‐hearing (DHH) children.Study DesignCross‐sectional study.SettingTertiary children's hospital.MethodsFour hundred forty parents of DHH children aged 0 to 17 completed the 25‐item Scale of Parental Involvement and Self‐Efficacy (SPISE) survey from 2014 to 2022. Residential addresses were geocoded and assigned Area Deprivation Index and Social Vulnerability Index rankings, and univariable and multivariable analyses were conducted using sociodemographic and clinical variables, including sex, race/ethnicity, insurance type, survey language, age at the survey, comorbidities, newborn hearing screening results, and hearing loss laterality and severity.ResultsCompared to English and Spanish‐speaking parents, Chinese‐speaking parents were associated with overall lower parental self‐efficacy and involvement (regression coefficient = −0.518, [−0.929, −0.106]), Cohen's d = 0.606) and lower scores on items related to their ability to affect multiple aspects of their child's development and expression of thoughts as well as competency in checking and putting on their child's sensory device. Across univariable and multivariable analyses, besides Chinese language, all other sociodemographic, clinical, and geographic variables were not associated with SPISE score.ConclusionTo achieve the best patient outcomes, care teams can use the SPISE to evaluate parental self‐efficacy and provide targeted support to parents at risk for having lower knowledge and confidence scores about critical skills necessary to facilitate their child's auditory access and language development. Notably, this study found similar reports of parental efficacy across various sociodemographic, clinical, and geographic variables but significantly lower SPISE scores in Chinese‐speaking families.
