Consumers’ decision-making self-efficacy for service purchases: construct conceptualization and scale

Abstract

Purpose The purpose of this study is to develop and validate a scale to determine the consumer’s level of decision-making self-efficacy for a high-involved service purchase, specifically the purchase of medical insurance. One question to ask is how service providers can help consumers purchase the services that best meet their needs? Before interventions can occur, it is necessary to benchmark consumers’ perceptions of their own decision-making control and abilities. Design/methodology/approach A scale that measures consumers’ service decision-making self-efficacy was developed using the principles established for scale development validation. A four-study approach was used to reach the research objective. Findings The research consisted of four studies designed to: generate items to measure consumer service decision-making self-efficacy (CSDMSE); purify the scale and assess its dimensionality (second-order structure); establish the reliability and validity of the scale; and establish norms to provide details on its usefulness for aiding consumers with service purchases. The scale was found to be a higher-order construct, comprising three lower-order constructs. Originality/value Research suggests that consumer self-efficacy may affect their decision-making. The greater the consumer’s self-efficacy for decision-making tasks, the more efficient the decision-making process strategies are expected to be. This is the purpose for which the CSDMSE scale measure was created: to understand how, where and when service professionals can assist consumers with making appropriate service-related decisions and purchases.
