Korean Stigma Scale Validated; Linked to Later Distress

Researchers at Chungbuk National University have validated a Korean version of the Social Stigmatization Scale, providing evidence that perceived social stigmatization is prospectively associated with subsequent psychological distress among young adults. The study, published in Frontiers in Psychiatry, utilized a two-wave longitudinal design to examine the psychometric properties of the scale and its relationship with mental health outcomes over a seven-week period. The findings suggest that the instrument, available in both an original 18-item and a modified 13-item format, serves as a reliable measure for assessing how individuals perceive devaluation and social constraints within mainstream society.

The research focused on Korean young adults aged 20 to 39, a demographic identified in national policies as a priority group for youth support. The study recruited 400 participants from an online panel using quota sampling, ensuring representation across gender identity, age, and residential regions. All participants reported experiencing perceived social stigmatization in at least one social domain, such as employment status, income, or physical health. This specific inclusion criterion allowed the researchers to examine the scale’s validity among individuals actively navigating stigmatized identities, rather than the general population.

Social stigmatization, as conceptualized in the study, refers to an individual’s perception of being devalued or socially constrained by mainstream societal beliefs. It is distinct from enacted discrimination, which involves actual discriminatory acts, and internalized stigma, which involves adopting negative beliefs about oneself. The Social Stigmatization Scale assesses the extent to which individuals perceive negative judgment, dehumanization, and restricted opportunities due to prejudice. By focusing on these perceptions, the scale captures the subjective experience of stigma across multiple social domains, offering a broader perspective than measures limited to specific groups or conditions.

The psychometric evaluation involved exploratory and confirmatory factor analyses to determine the scale’s structural validity. The original 18-item scale, which includes five reverse-scored items, demonstrated acceptable fit when a method factor was applied to account for the shared variance among the reverse-worded items. Alternatively, a modified 13-item version, which excluded the reverse-scored items, showed a robust unidimensional structure with high internal consistency. Both versions exhibited strong correlations with related constructs, such as social exclusion and the thwarting of basic psychological needs, supporting their construct validity. The 13-item version was noted as a more parsimonious option for research contexts where shorter administration times are preferred.

In the longitudinal component of the study, 260 participants completed a follow-up survey approximately seven weeks after the initial assessment. The researchers employed a cross-lagged panel model to analyze the temporal relationships between social stigmatization, perceived stress, and psychological distress. This statistical approach allows for the examination of how baseline levels of one variable predict subsequent changes in another, while controlling for the stability of each variable over time. The model included gender identity, monthly income, and educational attainment as covariates to account for potential demographic influences on mental health outcomes.

The results indicated that social stigmatization scores demonstrated significant temporal stability, with a standardized autoregressive coefficient of 0.59. This stability suggests that perceptions of social stigmatization are not merely transient mood states but reflect relatively persistent views of one’s social position. More importantly, baseline social stigmatization was a significant predictor of psychological distress at the seven-week follow-up, with a standardized path coefficient of 0.11. This association remained significant even after accounting for the stability of psychological distress and other control variables, providing preliminary evidence for a prospective link between perceived stigma and later mental health difficulties.

Perceived stress was also included in the longitudinal model to determine if it mediated the relationship between stigmatization and distress. The analysis revealed that baseline social stigmatization was associated with subsequent perceived stress, with a coefficient of 0.21. However, perceived stress did not significantly predict later psychological distress in this model. This finding implies that the association between social stigmatization and psychological distress is not fully explained by general stress responses. Instead, the experience of being socially devalued may have a distinct impact on mental health that extends beyond typical stress pathways.

Participants most frequently reported feeling stigmatized due to their employment type and monthly income, with 41.0% and 40.0% of the sample endorsing these domains, respectively. These findings align with broader societal values in South Korea, where economic achievement is highly prioritized. The study noted that all participants in their 30s with monthly incomes below 3 million KRW reported experiencing social stigmatization, highlighting the pressure associated with meeting economic expectations in this age group. Appearance and educational attainment were also common domains of perceived stigma, reflecting the competitive and hierarchical nature of Korean society.

The study acknowledges several limitations that temper the interpretation of its findings. The use of quota sampling from an online panel may limit the generalizability of the results to the broader population, as the sample consisted only of individuals who already perceived themselves as stigmatized. Additionally, the longitudinal design, while useful for establishing temporal precedence, does not prove causation. The seven-week interval provides short-term evidence, and further research with longer follow-up periods is needed to understand the long-term impact of social stigmatization on mental health. The study also did not include individuals with diverse gender identities, which may affect the comprehensiveness of the findings regarding compounded stigma.

Despite these limitations, the study contributes valuable psychometric evidence for the Social Stigmatization Scale in a Korean context. The validation of both the 18-item and 13-item versions offers researchers and clinicians flexible tools for assessing perceived social devaluation. The preliminary longitudinal evidence suggests that social stigmatization is a meaningful psychosocial construct that may serve as a risk factor for psychological distress. Recognizing stigma as a socially embedded experience, rather than solely an individual vulnerability, could inform mental health services and research aimed at supporting young adults in competitive and hierarchical societies.

The distinction between economic stress and social stigmatization is crucial for understanding the mental health challenges faced by Korean young adults. While economic stress refers to the direct burden of insufficient income, social stigmatization involves the feeling of being socially devalued because of such conditions. This dual experience can exacerbate psychological vulnerability by limiting access to social capital and increasing feelings of isolation. The findings underscore the importance of addressing the social and cultural dimensions of economic hardship in mental health interventions.

The stability of social stigmatization over the seven-week period suggests that these perceptions are deeply rooted in societal definitions of normalcy and success. This persistence may make it difficult for individuals to disengage from stigmatizing beliefs without broader societal changes. The study highlights the need for interventions that address the structural and interpersonal factors contributing to stigma, rather than focusing exclusively on individual coping strategies. By validating a tool that captures these experiences, the research provides a foundation for future studies exploring the mechanisms through which social stigmatization impacts mental health.

Beyond broad eligibility criteria, the research team implemented stringent data-screening protocols across both waves of data collection. From an initial pool of 940 individuals who accessed the online survey platform, 268 failed baseline screening criteria and 192 discontinued their participation. The investigators subsequently excluded 80 respondents for careless engagement, which included 43 displaying repetitive patterns such as straight-lining, 24 failing embedded validity checks, nine completing responses too rapidly, and four endorsing all 13 listed stigma categories as potential indiscriminate responders. The resulting baseline cohort comprised 200 men and 200 women with an average age of 30.8 years, of whom 17.8 percent reported high school education or less, while the remaining participants held at least a community college degree.

Analysis of perceived stigma distributions revealed substantial variation across domains, with 30.8 percent reporting one domain, 26.8 percent identifying two, and remaining participants endorsing between three and seven. Outside occupational status, physical appearance was cited by 29.0 percent of respondents, educational attainment by 27.8 percent, and physical health status by 20.5 percent. Although reported by only 17.0 percent of the cohort, mental health status exhibited both the highest average social stigmatization score and the greatest frequency of co-occurrence with other domains. Construct validity evaluations using the Interpersonal Behaviours Questionnaire further demonstrated that stigmatization scores correlated more strongly with the thwarting of basic psychological needs, specifically competence, relatedness, and autonomy, than with the simple absence of supportive psychological fulfillment.

Follow-up retention dynamics also introduced important analytical considerations for the longitudinal model. Of the original 400 respondents, 284 completed the second assessment, and 24 were removed for careless responses, leaving 260 participants. Comparisons between these retained participants and the 140 individuals who did not participate in the retest revealed no significant demographic differences regarding age, educational level, monthly income, gender, or employment status. However, retained individuals exhibited significantly higher baseline scores for perceived stigmatization, total endorsed domains, psychological distress, and perceived stress. The final cross-lagged model accounted for 67.5 percent of the variance in psychological distress at follow-up, 34.5 percent in social stigmatization, and 4.8 percent in perceived stress, reflecting differential predictive capacity across constructs.

Finally, the authors noted specific structural constraints regarding the psychometric evaluation. Although translation and back-translation procedures were completed, the Korean instrument did not undergo broader cultural adaptation, which may be relevant given known measurement nuances of reverse-worded items in East Asian settings. Furthermore, while splitting the 400 participants into independent exploratory and confirmatory subsamples prevented overfitting within a single group, each subsample contained 200 respondents, representing a relatively modest size for evaluating an 18-item instrument.
