IntroductionA positive childbirth experience and satisfaction are the key indicators defining the quality of care pregnant mothers receive in a healthcare institution. Therefore, researchers have sought multiple strategies to improve childbirth experience and maternal satisfaction. In light of this background, the current research aims to evaluate the effectiveness of peanut ball intervention in improving maternal satisfaction and promoting positive childbirth experiences and behavioural responses. MethodsThe current research employed a randomised control trial in which 768 low-risk primigravid women were recruited into two groups: treatment (n = 384) and control (n = 384). A comparative evaluation of the outcomes was carried out between the peanut ball intervention provided to the treatment group and the standard care provided to the control group. Data was collected using an observation checklist for behavioural response and a questionnaire for childbirth experience and maternal satisfaction. ResultsThe study revealed a significant mean score difference in behavioural response, childbirth experience and maternal satisfaction, indicating the effectiveness of the peanut ball intervention in improving these outcomes. ConclusionThe peanut ball intervention can effectively improve positive behavioural response, childbirth experience and maternal satisfaction among low-risk primigravid women. The current study provides insight into healthcare providers' consideration of the peanut ball intervention among pregnant mothers as a safe and comfortable method of childbirth.
