# Measuring the multidimensional reputation of a medicines regulatory agency: development and validation of a public-oriented scale

## TL;DR

This study creates and validates a survey to measure the public's perception of a medicines regulatory agency's reputation in South Korea.

## Contribution

A validated, public-oriented survey instrument for measuring the multidimensional reputation of regulatory agencies.

## Key findings

- A three-dimensional reputation structure was identified: performance, procedure, and technical competence.
- The agency's overall reputation score was 72 out of 100, with technical competence rated highest.
- The survey demonstrated strong validity and reliability for measuring public perception.

## Abstract

The reputation of public agencies, encompassing the dimensions of performance, morality, procedure, and technical competence, is fundamental to understanding their behavior. However, standardized, individual-level measures of reputation suitable for surveys targeting the general public are lacking. This study aims to develop and validate a survey instrument for the general public to measure the multi-dimensional reputation of public agencies, with a focus on South Korea’s medicines regulatory agency.

Survey items were developed based on previous literature, refined through expert consultation, and validated through a population survey. The validation study involved 1,000 participants from the public, selected using a quota sampling method stratified by age, sex, and region, according to the South Korean census. Validity was assessed through exploratory factor analysis and hypothesis testing, while reliability was evaluated using internal consistency.

Exploratory factor analysis identified a three-dimensional structure of reputation, encompassing performance, procedure, and technical competence, while morality was not distinctly identified as a separate dimension. Construct validity, including convergent and discriminant validity, was confirmed. The internal consistency of the three dimensions was acceptable, with Cronbach’s alpha coefficients ranging from 0.87 to 0.91. The overall reputation of the medicines regulatory agency was measured at 72 out of 100. The specific dimension scores were as follows: 74 for technical competence, 71 for performance, and 70 for procedure.

The agency should recognize the multidimensional nature of reputation and foster an environment that enables the public to observe and evaluate these dimensions. Reputation management strategies should emphasize not only technical expertise but also performance and procedural aspects to ensure a well-rounded reputation.
