Abstract
The Stigma Scale (SS-Devaluation), formally and widely known in psychiatric epidemiology and medical sociology as the Perceived Devaluation-Discrimination Scale (PDD), was developed by Bruce G. Link in 1987 to operationalize the core tenets of modified labeling theory. The scale quantifies the extent to which an individual believes that society at large devalues, marginalizes, and discriminates against individuals who have received mental health treatment or been diagnosed with a psychiatric disorder. Comprising 12 self-report items, the instrument uses a balanced design consisting of six positively worded items (affirming social acceptance, trustworthiness, and competence) and six negatively worded items (affirming societal rejection, personal failure, and professional exclusion). Respondents rate their level of agreement on either a 6-point or 4-point Likert scale, with standardized reverse-scoring yielding a composite index where higher scores systematically reflect greater perceived societal devaluation and discrimination.
Psychometrically, the instrument demonstrates robust internal consistency reliability, with Cronbach’s alpha coefficients consistently falling between 0.82 and 0.89 across diverse psychiatric, clinical, community, and cross-cultural cohorts. Test-retest reliability across multi-month intervals demonstrates temporal stability ($r = 0.70$ to $0.84$), confirming its utility as a trait-like measure of internalized sociocultural expectations. Factor analytic studies largely endorse an overarching unidimensional construct of perceived public stigma, though some structural equation modeling investigations identify two closely correlated sub-dimensions: perceived devaluation of personal worth and perceived structural or interpersonal discrimination. Construct, convergent, and predictive validities are thoroughly documented; elevated scores correlate significantly with demoralization, diminished self-esteem, heightened social withdrawal, fear of disclosure, compromised quality of life, and treatment non-adherence. As one of the most cited measures in psychiatric stigma research, the SS-Devaluation remains foundational for evaluating intervention efficacy, public health anti-stigma campaigns, and the psychosocial trajectories of individuals living with mental illness.

Purpose
The primary purpose of the Stigma Scale (SS-Devaluation) is to measure an individual’s perception of the general public’s attitudes toward individuals with serious mental illness. Rather than soliciting an individual’s personal prejudices or endorsement of stereotypes (e.g., asking “Do you think people with mental illness are dangerous?”), the scale measures respondents’ appraisals of prevailing normative attitudes within their broader societal collective (e.g., asking “Most people think that someone who has been in a serious mental health facility is dangerous”). This third-person referent design (“most people”) serves critical methodological, psychometric, and theoretical functions.
Methodologically, inquiring about what “most people” believe circumvents the pervasive challenge of social desirability bias. When questioned directly regarding personal prejudices against psychiatric patients, respondents frequently provide egalitarian responses to conform to social norms. However, when evaluating the societal climate, participants report candidly on the structural and interpersonal devaluation they observe or anticipate. For psychiatric patients, this measure captures the precise cognitive lens through which they evaluate their own vulnerability to status loss, interpersonal rejection, and employment discrimination.
In clinical, psychiatric, and epidemiological contexts, the instrument serves multiple operational purposes:
- Assessing Anticipated Social Threat: For individuals newly diagnosed with mental health conditions or entering psychiatric treatment, the scale operationalizes the psychological threat of anticipated rejection, which frequently triggers maladaptive coping strategies such as social isolation, treatment non-disclosure, and therapeutic disengagement.
- Predicting Clinical and Functional Outcomes: High baseline levels of perceived devaluation-discrimination robustly predict declines in global self-worth, reductions in social network size, unemployment duration, depressive symptom exacerbation, and elevated demoralization.
- Program Evaluation and Policy Research: The scale provides a standardized metric to evaluate whether macro-level public health interventions, anti-stigma media initiatives, or psychiatric rehabilitation programs alter the perceived climate of rejection within communities or clinical cohorts.
- Differentiating Stigma Levels: When administered in parallel to psychiatric patients, their family caregivers, and the general public, the SS-Devaluation illuminates discrepancies between actual public attitudes and the anticipated discrimination feared by individuals with lived experience.
Psychological Construct
The construct captured by the SS-Devaluation is Perceived Devaluation and Discrimination, defined as an individual’s subjective appraisal of the degree to which typical members of society hold negative stereotypes about, withhold social acceptance from, devalue the moral worth of, and act restrictively toward people with psychiatric histories. This construct sits at the nexus of cognitive appraisal, social cognition, and social structural inequality. It represents an internalized cognitive schema regarding societal marginalization that develops long before any personal diagnosis through pervasive cultural socialization.
Core Sub-Dimensions of the Construct
Although typically evaluated as a consolidated unitary construct, the 12 items operationalize several distinct facets of social devaluation:
- Interpersonal Trustworthiness and Moral Character: Items 2, 3, and 8 interrogate assumptions regarding the intellectual, moral, and functional integrity of individuals who have experienced psychiatric hospitalization. The construct examines whether society views such individuals as essentially deficient in cognitive capacity, reliability, and fundamental trustworthiness compared to the average citizen.
- Social Distance and Relational Closeness: Items 1, 4, and 10 appraise the willingness of the social collective to integrate former patients into proximal and intimate social spheres. This dimension contrasts superficial tolerance with deep interpersonal integration, such as welcoming an individual as a close personal confidant or entrusting them with significant social roles, such as public school instruction.
- Status Loss and Diminished Social Standing: Items 5 and 6 measure the symbolic degradation and loss of prestige tied to psychiatric contact. This involves perceptions that psychiatric admission represents an indelible mark of personal failure or an irreversible compromise of social esteem.
- Appraisals of Dangerousness and Unpredictability: Item 9 probes the pervasive cultural stereotype linking mental illness with inherent peril, physical threat, or volatile behavior, which acts as a primary justification for exclusionary behavior.
- Structural and Economic Discrimination: Items 7, 11, and 12 assess institutional and instrumental exclusion, focusing heavily on childcare disqualification, labor market bias, hiring discrimination, and dismissive treatment in formal discourse. This reflects the realization that perceived stigma has tangible economic and material repercussions.
The construct differs fundamentally from endorsed stigma (personal prejudice held by the respondent) and experienced stigma (retrospective accounts of actual discriminatory events). Instead, perceived devaluation-discrimination represents an anticipatory cognitive schema. Even if an individual has never directly experienced overt hostility, a high score indicates the conviction that disclosure of a psychiatric status will inevitably trigger societal rejection, vocational compromise, and social death.
Theoretical Framework
The SS-Devaluation is directly anchored in Modified Labeling Theory, developed by Bruce G. Link and colleagues (Link, 1987; Link et al., 1989) as an extension of original sociological labeling theory (Scheff, 1966) and Erving Goffman‘s foundational conceptualization of stigma as a “spoiled identity” (1963).
The Five-Stage Architecture of Modified Labeling Theory
Modified Labeling Theory explains how institutional labels permanently reshape an individual’s identity, interpersonal behavior, and socioeconomic trajectory. The framework unfolds across five interdependent stages:
- Cultural Socialization of Stereotypes: Prior to developing any mental illness, individuals are thoroughly socialized into cultural norms via media representations, peer discussions, and institutional practices. Through this process, they acquire internal cognitive schemas regarding what “most people” think of “mental patients”—specifically, that society devalues and discriminates against them.
- Labeling Event (Official Diagnosis and Treatment): When psychological distress or behavioral disruption leads an individual into formal psychiatric care, official labeling occurs. Diagnostic categorization transforms abstract cultural beliefs into personally relevant vulnerabilities.
- Schema Activation and Anticipated Rejection: The previously passive cultural expectations measured directly by the SS-Devaluation become acutely salient. The labeled individual recognizes that the societal contempt they long recognized as applying to “those people” now directly applies to themselves.
- Maladaptive Coping Orientations: To defend against anticipated status loss and discrimination, individuals deploy defensive coping strategies, primarily: (a) Secrecy (concealing treatment history), (b) Social Withdrawal (restricting social circles exclusively to those who know and accept them, or becoming isolated), and (c) Education (attempting to enlighten others to preempt stigma).
- Negative Structural and Psychosocial Sequelae: Paradoxically, these defensive maneuvers often yield severe negative consequences. Concealment induces sustained anxiety and hypervigilance; withdrawal dismantles social capital, reduces social networks, exacerbates depressive symptoms, and limits employment opportunities. Ultimately, vulnerability to subsequent psychopathology increases, fulfilling a self-fulfilling prophecy initiated by the label.
Within this theoretical model, the SS-Devaluation measures the critical mediating cognitive variable: the magnitude of societal devaluation expected by the individual. Without this internalized cognitive representation, the application of a psychiatric label would lack its corrosive power over psychological well-being and social functioning.
Validity
The psychometric validity of the SS-Devaluation has been established across hundreds of empirical investigations encompassing clinical, epidemiological, community, and cross-cultural populations.
Construct and Convergent Validity
Construct validity is evidenced by robust correlations with related psychometric measures of psychological distress, identity impairment, and stigma. Extensive validation studies demonstrate that elevated scores on the SS-Devaluation correlate positively and significantly with:
- The Internalized Stigma of Mental Illness (ISMI) Scale ($r = 0.45$ to $0.62$), illustrating that high perceived devaluation operates as a key developmental precursor to internalized self-stigma.
- The Center for Epidemiologic Studies Depression (CES-D) Scale ($r = 0.28$ to $0.44$), supporting the theoretical link between anticipation of social devaluation and depressive symptom severity.
- Measures of demoralization, subjective isolation, and psychological vulnerability across both outpatient and residential psychiatric cohorts.
Conversely, the scale demonstrates strong negative correlations with the Rosenberg Self-Esteem Scale ($r = -0.30$ to $-0.48$) and generalized perceived social support ($r = -0.25$ to $-0.41$). Individuals who perceive intense societal rejection routinely display fractured self-worth and constricted interpersonal support networks.
Discriminant Validity
Discriminant validity has been confirmed by examining the scale’s distinction from symptom severity scales and generalized social anxiety. Although perceived devaluation correlates moderately with depressive symptomatology, confirmatory factor models confirm that items measuring societal devaluation load onto separate factors from psychiatric symptoms, general negative affectivity, and neuroticism. The scale specifically indexes appraisals of external sociocultural attitudes rather than generalized internal distress.
Predictive and Longitudinal Validity
Longitudinal studies demonstrate the predictive power of the SS-Devaluation. In prospective investigations tracking individuals following psychiatric discharge (Link et al., 1997; Markowitz, 1998; Perlick et al., 2001):
- Baseline scores on the scale predicted significant reductions in full-time employment status and lower median earnings over a 24-month follow-up period, controlling for baseline diagnosis, clinical severity, and educational attainment.
- High scores predicted increased rates of premature psychiatric treatment termination and clinic dropout, mediated by defensive avoidance of healthcare settings to prevent public labeling.
- In cohorts diagnosed with bipolar disorder and schizophrenia spectrum disorders, high perceived devaluation-discrimination prospectively predicted reduced adherence to psychopharmacological regimens, sustained social network attrition, and decreased quality of life over longitudinal observations.
Reliability
The reliability of the SS-Devaluation has been tested across varied experimental, clinical, and community designs.
Internal Consistency Reliability
Across validation literature, the internal consistency of the 12-item scale consistently meets or exceeds standard psychometric criteria ($\alpha ge 0.80$):
- Original Validation Cohorts (Link, 1987): Link reported an overall Cronbach’s alpha of $0.84$ in a comparative sample of psychiatric patients and community residents. Corrected item-total correlations ranged from $0.38$ to $0.63$.
- Subsequent Clinical Replications: In a major longitudinal study of 164 mental health consumers, Link, Struening, Rahav, Phelan, and Nuttbrock (1997) reported an alpha of $0.86$. Perlick et al. (2001) observed an alpha of $0.88$ among caregivers and patients managing affective disorders.
- Cross-Cultural Adaptations: Cross-national studies validate consistent internal consistency across diverse linguistic and cultural environments. The German validation (Matschinger et al., 1991) documented an alpha of $0.83$; the Swedish version (Björkman et al., 2008) yielded an alpha of $0.84$; the Chinese adaptation (Lee et al., 2007) demonstrated an alpha of $0.82$; and the Spanish adaptation (Muñoz et al., 2011) produced an alpha of $0.86$.
Temporal Stability (Test-Retest Reliability)
Because the scale measures deeply engrained cultural appraisals, it displays marked stability over time in the absence of targeted anti-stigma interventions. In community samples assessed across a six-week interval, the test-retest reliability coefficient was $r = 0.82$ ($p < 0.001$). Over broader six-month intervals among stable psychiatric outpatients, intraclass correlation coefficients (ICC) have consistently ranged between $0.70$ and $0.78$, demonstrating that the instrument measures a stable cognitive appraisal rather than transient affective fluctuations.
Factor Analysis
Extensive exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) have investigated the latent structure of the 12-item instrument.
Unidimensional Structure vs. Method Effects
Link’s original 1987 formulation conceptualized the scale as a unidimensional continuum of perceived devaluation-discrimination. Early principal components analyses yielded an initial primary eigenvalue accounting for substantial variance, with all 12 items demonstrating substantial loadings ($λ > 0.40$). However, several subsequent structural studies identified a two-factor solution that corresponds closely to item phrasing:
- Factor 1: Perceived Devaluation / Social Rejection: Defined by the negatively keyed items (Items 5, 6, 7, 9, 11, and 12), focusing directly on personal failure, danger, social dismissal, and employment discrimination.
- Factor 2: Perceived Acceptance / Social Competence: Defined by the positively keyed items (Items 1, 2, 3, 4, 8, and 10), reflecting societal willingness to accept individuals as friends, teachers, and trustworthy citizens.
Subsequent psychometric modeling (e.g., Brohan et al., 2010; Matschinger et al., 1991) using advanced confirmatory techniques demonstrated that this apparent two-factor structure largely represents a methodological artifact—specifically, an acquiescence method effect stemming from the balance between positively and negatively worded statements. When models include a general trait factor alongside orthogonal method factors for reverse-worded items (bifactor structure), the general factor of perceived devaluation accounts for the vast majority of common variance.
Confirmatory Factor Analytic Fit Indices
Modern CFA investigations evaluating the unidimensional model with correlated error terms or a bifactor structure report acceptable-to-excellent model fit across various samples:
- Comparative Fit Index (CFI): Consistently ranges from $0.93$ to $0.97$.
- Tucker-Lewis Index (TLI): Typically ranges from $0.91$ to $0.96$.
- Root Mean Square Error of Approximation (RMSEA): Standard estimates range from $0.045$ to $0.062$ ($90% \text{ CI } [0.038, 0.071]$).
- Standardized Root Mean Square Residual (SRMR): Commonly observed below $0.05$.
Factor loadings for individual items onto the primary perceived devaluation construct are detailed in the literature as ranging between $λ = 0.42$ (e.g., Item 2 regarding intelligence) and $λ = 0.74$ (e.g., Item 5 regarding thinking less of a person, and Item 11 regarding employment discrimination).
Instrument / Measurement Tool
The SS-Devaluation is structured for rapid administration, high interpretability, and methodological balance.
- Instrument Name: Stigma Scale (SS-Devaluation) / Perceived Devaluation-Discrimination Scale (PDD).
- Construct Assessed: Perceived societal devaluation, social rejection, and structural/interpersonal discrimination directed toward individuals with a history of serious mental illness or psychiatric hospitalization.
- Administration Format: Self-report paper-and-pencil or computer-assisted administration; can also be delivered via trained clinical interviewers.
- Target Population: Adults and adolescents (ages 15+), validated across individuals with psychiatric conditions, family caregivers, healthcare providers, and the general public.
- Completion Time: Approximately 3 to 5 minutes.
- Total Item Count: 12 items.
- Response Scale:
- Primary 6-point Likert scale: 1 = Strongly Agree, 2 = Agree, 3 = Agree somewhat, 4 = Disagree somewhat, 5 = Disagree, 6 = Strongly Disagree
- Alternative 4-point Likert scale: 1 = Strongly Disagree, 2 = Disagree, 3 = Agree, 4 = Strongly Agree
- Item Valence and Directionality:
- Positively phrased items (Acceptance): Items 1, 2, 3, 4, 8, 10. (These describe a society that accepts, respects, and trusts individuals who have experienced mental illness or psychiatric care.)
- Negatively phrased items (Devaluation/Discrimination): Items 5, 6, 7, 9, 11, 12. (These describe a society that devalues, fears, and discriminates against individuals who have experienced mental illness or psychiatric care.)
- Scoring Methodology:
- To compute a composite scale where higher scores reflect higher perceived devaluation and discrimination:
- When using the 6-point scale (1 = Strongly Agree to 6 = Strongly Disagree): Items indicating acceptance (1, 2, 3, 4, 8, 10) are retained in their natural coding ($1 = 1$ to $6 = 6$), where disagreement indicates perceived devaluation. Items indicating devaluation (5, 6, 7, 9, 11, 12) are reverse-coded ($1 = 6, 2 = 5, 3 = 4, 4 = 3, 5 = 2, 6 = 1$) so that agreement reflects high devaluation.
- When using the 4-point scale (1 = Strongly Disagree to 4 = Strongly Agree): Items indicating acceptance (1, 2, 3, 4, 8, 10) are reverse-scored ($1 = 4, 2 = 3, 3 = 2, 4 = 1$), while items indicating devaluation (5, 6, 7, 9, 11, 12) are scored directly ($1 = 1, 2 = 2, 3 = 3, 4 = 4$).
- Overall Composite Score: Calculated as the arithmetic mean of all 12 items (yielding a range of 1.0 to 6.0 on the 6-point version, or 1.0 to 4.0 on the 4-point version). A midpoint threshold ($> 3.5$ on the 6-point scale; $> 2.5$ on the 4-point scale) denotes an overall perception that society leans toward devaluing and discriminating against psychiatric service users.

Items of the Scale
Response Scale:
6-point Likert scale: 1 = Strongly Agree, 2 = Agree, 3 = Agree somewhat, 4 = Disagree somewhat, 5 = Disagree, 6 = Strongly Disagree (or commonly administered as a 4-point scale: 1 = Strongly Disagree, 2 = Disagree, 3 = Agree, 4 = Strongly Agree)
Reverse Scoring Rules:
Six items are worded such that agreement indicates perceived devaluation/discrimination (items 1, 2, 3, 4, 8, 10), and six items are reverse-coded such that disagreement indicates perceived devaluation/discrimination (items 5, 6, 7, 9, 11, 12). Higher scores reflect greater perceived devaluation and discrimination.
