Development and Psychometric Evaluation of a Questionnaire Based on the Nursing Outcomes Classification to Determine the Knowledge of Parents on Breast‐Feeding: Research Protocol

Purpose To develop and psychometrically evaluate a questionnaire based on the outcome “Knowledge: Breast‐feeding” of the Nursing Outcomes Classification ( NOC ) to determine the knowledge of parents on breast‐feeding. Background The NOC outcome “Knowledge: Breast‐feeding” allows for nurses/midwives to assess the efficacy of interventions aimed to improve the knowledge on breast‐feeding in parents thought the clinical interview/observation. However, the use of self‐administered questionnaires by patients could facilitate its evaluation. Methods Two‐phased study: (1) Development of the questionnaire based on experts' opinions; (2) Methodological design to assess its psychometric properties. Implications for Nursing Practice The availability of tools that enable the determination of the knowledge of patients would facilitate nurses/midwives to set objectives, individualize interventions, and measure their effectiveness.
