다국어 초록 (Multilingual Abstract)

This study is a usability evaluation of “Solcounsel” an anonymous SNS-based mobile mental-health counseling service platform that comprehensively addresses mental-health issues and is directly developed, operated, and provided counseling services by mental-health social work expert. For the study, usability was assessed using the Mobile Application Rating Scale (MARS) with mental-health social-work experts, and an expert Focus Group Interview (FGI) was subsequently conducted based on these results.The findings indicated that, among the objective evaluation indicators, the domains related to behavior change—such as the reliability of information provided, the potential for behavior change, and the user’s help-seeking tendencies—received notably positive evaluations. In contrast, the objective indicators for engagement, interest, personalization, aesthetics, and functional usability showed clear limitations. It was found that experts generally rated the overall score for app use within the subjective quality assessment domain as average or below, indicating that the platform requires substantial overall improvement, particularly in its UI/UX aspects. Based on these findings, the study presents practical and policy recommendations aimed at supplementing existing qualitative research on platform developers and user experiences, exploring future directions for redesigning the platform into a more professional and mainstream mobile mental-health counseling service, and providing academic evidence to enhance its potential for broader public utilization.
