Development of Instrument to Assess School-age Children's Self-efficacy Related to Having Injection and Venipuncture

Abstract

The purpose of this study was to develop the instrument to assess the school-age children's self-efficacy related to having injections and venipunctures. An 15-item self-report instrument of "School-age Children's Self-efficacy for Painful Medical Procedures" was developed to measure children's beliefs of their own ability of how much they can conduct their behavior to deal with having repeated injections and venipunctures. Items were generated based on the result of the fieldwork and literature. Through content analysis, items were supported as relevant to the concept definition. Conceptual correlations between "School-age Children's Self-efficacy for Painful Medical Procedures" with "Stress Response Scale for Children (SRS-C)" (r = -.70, p< .01) and "Self-esteem Scale" (r = .39, p< .01) highly supported it's conceptual validity. Cronbach's a for the entire instrument was .95. The result of test-retest (r = .88, p< .01) supported the instrument's reliability.
