Psychosocial predictors of parental participation in ultrasound screening for developmental dysplasia of the hip

摘要

Ultrasound screening for developmental dysplasia of the hip (DDH) is an innovation in preventive child health care in the Netherlands. Parental participation in the screening will be essential for the success of implementation of the screening. The aim of the current study was to investigate whether psychosocial factors (attitude, subjective norm, self-efficacy, perceived susceptibility, perceived severity, perceived effectiveness) predicted parental participation in the screening. A cross-sectional survey was conducted. Using a questionnaire, several background variables (organization, sociodemographic variables, and knowledge) and psychosocial variables were collected. Blockwise logistic regression was used to analyze the relations. A total of 703 questionnaires of participating parents (response 61.7%) and 393 questionnaires of nonparticipating parents were received (response 37.2%). When controlling for the background variables, attitude, subjective norm, self-efficacy, perceived susceptibility, and perceived effectiveness predicted parental participation in the screening (p < .05). Perceived severity of the dysplasia did not predict participation (p > .05). Psychosocial determinants influenced parental participation in the ultrasound screening for DDH. Emphasizing the positive aspects of the screening, highlighting the effectiveness, removing practical barriers, and being conscious of the influential role of child health care professionals on decision making are areas to focus on when organizing the ultrasound screening for DDH. Health care policy decision makers and child health care professionals should consider these determinants in order to stimulate parental participation.
