A Psychometric Review of Measures Assessing Discrimination Against Sexual Minorities

"We Can Do Better": Developing Attitudinal Scales Relevant to LGBTQ2S+ Issues-A Primer on Best Practice Recommendations for Beginners in Scale Development

In this primer, following best practice recommendations and drawing upon their own expertise in psychometrics, the authors provide a step-by-step guide for developing measures relevant to sexual- and gender-marginalized persons (SGMPs). To ensure that readers operate from a uniform understanding, definitions for central elements of psychometric testing (e.g., reliability and validity) are provided. Then, detailed information is given about developing and refining scale items. Strategies designed to reduce a pool of items to a manageable number are also highlighted. The authors conclude this primer by discussing various forms of validation (e.g., convergent, discriminant, and known groups). To further readers' understanding, illustrative examples from measures designed for SGMPs are brought into focus throughout.

Use of the Heterosexist Harassment, Rejection, and Discrimination Scale With Different Sexual Orientation, Gender, and Racial/Ethnic Groups: An Examination of Measurement Invariance

The Heterosexist Harassment, Rejection, and Discrimination Scale (HHRDS) is one of the most commonly used measures of sexual orientation-related discrimination, but little is known about its psychometric properties across different sexual orientations, gender, and racial/ethnic groups. A three-factor model was initially obtained, but most studies treat the HHRDS unidimensionally. Therefore, we tested whether the HHRDS exhibited measurement invariance across sexual orientation, gender, and racial/ethnic groups among 792 sexual minority young adults (aged 18-29) who participated in an online study. Across models, the three-factor solution fit better than the one-factor solution. All models achieved configural invariance and most achieved metric invariance; none of the considered models achieved scalar invariance (1-3 items were not equivalent across groups, depending on the comparison). Findings suggest that the HHRDS generally functions equivalently across sexual orientation, gender, and racial/ethnic groups, but some caution in interpreting scores is warranted.

Review of Major Social Determinants of Health in Schizophrenia-Spectrum Disorders: II. Assessments

BACKGROUND AND AIMS

Social determinants of health (SDoHs) impact the development and course of schizophrenia-spectrum psychotic disorders (SSPDs). Yet, we found no published scholarly reviews of psychometric properties and pragmatic utility of SDoH assessments among people with SSPDs. We aim to review those aspects of SDoH assessments.

STUDY DESIGN

PsychInfo, PubMed, and Google Scholar databases were examined to obtain data on reliability, validity, administration process, strengths, and limitations of the measures for SDoHs identified in a paired scoping review.

STUDY RESULTS

SDoHs were assessed using different approaches including self-reports, interviews, rating scales, and review of public databases. Of the major SDoHs, early-life adversities, social disconnection, racism, social fragmentation, and food insecurity had measures with satisfactory psychometric properties. Internal consistency reliabilities-evaluated in the general population for 13 measures of early-life adversities, social disconnection, racism, social fragmentation, and food insecurity-ranged from poor to excellent (0.68-0.96). The number of items varied from 1 to more than 100 and administration time ranged from less than 5 minutes to over an hour. Measures of urbanicity, low socioeconomic status, immigration status, homelessness/housing instability, and incarceration were based on public records or targeted sampling.

CONCLUSIONS

Although the reported assessments of SDoHs show promise, there is a need to develop and test brief but validated screening measures suitable for clinical application. Novel assessment tools, including objective assessments at individual and community levels utilizing new technology, and sophisticated psychometric evaluations for reliability, validity, and sensitivity to change with effective interventions are recommended, and suggestions for training curricula are offered.

Development and Validation of the Military Minority Stress Scale

Despite affecting nearly 3% of active-duty service members, little is known about how LGBT-related stress experiences may relate to health outcomes. Thus, the present study sought to create a Military Minority Stress Scale and assess its initial reliability and construct validity in a cross-sectional study of active-duty LGBT service members (N = 248). Associations between 47 candidate items and health outcomes of interest were analyzed to retain those with substantial betas. Item response theory analyzes, reliability testing, invariance testing, and exploratory factor analysis were performed. Construct validity of the final measure was assessed through associations between the sum score of the final measure and the health outcomes. The final 13-item measure demonstrated an excellent reliability (ω = 0.95). Bivariate linear regressions showed significant associations between the sum score of the measure and overall health (β = -0.26, p < 0.001), overall mental health (β = -0.34, p < 0.001), physical health (β = 0.45, p < 0.001), life satisfaction (β = -0.24, p < 0.001), anxiety (β = 0.34, p < 0.001), depressive symptoms (β = 0.37, p < 0.001), suicidality (β = 0.26, p < 0.001), and PTSD (β = 0.42, p < 0.001), respectively. This study provides the first evidence that minority stressors in the military setting can be operationalized and measured. They appear to have a role in the health of LGBT service members and may explain the continued health disparities experienced by this population. Little is known regarding the experiences of LGBT active-duty service members, including experiences of discrimination. Understanding these experiences and their associated health outcomes during military service may therefore help and guide further etiological studies and intervention development.

The Development of Proud & Empowered: An Intervention for Promoting LGBTQ Adolescent Mental Health

Sexual and gender minority adolescents (SGMA) experience higher rates of internalizing psychopathology, including depression, anxiety, self-harm, and posttraumatic stress disorder. The primary explanation for these mental health disparities is minority stress theory, which suggests that discrimination, violence, and victimization are key drivers of chronic minority stress and place SGMA at higher risk of mental health concerns. To help address these concerns, the authors undertook a nearly 8-year process of developing Proud & Empowered, a school-based intervention to help SGMA cope with minority stress experiences. This manuscript details the intervention development process, including: (a) identifying the mechanisms of change (Stage 0), (b) building the intervention (Stage 1A, Part 1), (c) acceptability testing and program revision (Stage 1A, Part 2), (d) feasibility and pilot testing (Stage 1B, Part 1), (e) modification of the intervention to improve implementability (Stage 1B, Part 2), and (f) the final intervention.

Minority Stress and Loneliness in a Global Sample of Sexual Minority Adults: The Roles of Social Anxiety, Social Inhibition, and Community Involvement

Research suggests that loneliness among sexual minority adults is associated with marginalization, but it is unclear which processes may underlie this relationship. This cross-sectional study examined five possibilities: stigma preoccupation, internalized homonegativity, sexual orientation concealment, social anxiety, and social inhibition. The study also examined the possible protective role of LGBTQ community involvement. Respondents were 7856 sexual minority adults aged 18-88 years from 85 countries who completed an online survey. Results of structural equation modeling indicated that marginalization was positively associated with both social and emotional loneliness, and that part of this relationship was indirect via proximal minority stress factors (especially stigma preoccupation) and, in turn, social anxiety and social inhibition. Moreover, while LGBTQ community involvement was associated with greater marginalization, it was also associated with lower levels of proximal stress and both forms of loneliness. Among those who were more involved in the LGBTQ community, the associations between marginalization and proximal stress were somewhat weaker, as were those between stigma preoccupation and social anxiety, and between social inhibition and social loneliness. In contrast, the associations between concealment and social anxiety were somewhat stronger. Model fit and patterns of association were similar after controlling for the possible confounding effect of dispositional negative affectivity, but several coefficients were lower. Findings underscore the continuing need to counter marginalization of sexual minorities, both outside and within the LGBTQ community, and suggest possible avenues for alleviating loneliness at the individual level, such as cognitive-behavioral interventions targeting stigma preoccupation and social anxiety.

Sexual Minority Stressors and Intimate Partner Violence Among Same-Sex Couples: Commitment as a Resource

Accumulating evidence has been found for the associations from sexual minority stressors to intimate partner violence (IPV) among same-sex couples. Yet key gaps still exist, including the rare utilization of couple dyadic data, the understudied moderating and mediating mechanisms, and the few studies conducted during the transitional period of same-sex marriage legalization. To address these gaps, we used cross-sectional, dyadic data collected from 144 US same-sex couples during the 2014-2015 national campaign for the legalization of same-sex marriage. Guided by the systemic transactional model (STM), we examined associations from sexual minority stressors (including both internalized homophobia and discrimination) to same-sex IPV and tested whether commitment moderated or mediated these associations. Overall, we found evidence supporting the STM: (1) High internalized homophobia and discrimination were related to high prevalence and/or frequency of IPV perpetration; (2) high commitment attenuated positive associations between high discrimination and high prevalence and/or frequency of IPV perpetration; and (3) high internalized homophobia was related to low commitment, which in turn was related to high prevalence and/or frequency of IPV perpetration. Collectively, our study identified commitment as both a moderator and mediator in associations from sexual minority stressors to same-sex IPV. Further, the roles of commitment (i.e., moderator or mediator) depend on whether the focal sexual minority stressors are distal and more intermittent (i.e., heterosexist discrimination) or proximal and more constant (i.e., internalized homophobia).

Adolescent stress experiences over time study (ASETS) protocol: design and methods of a prospective longitudinal study of sexual minority adolescents in the USA

INTRODUCTION

Sexual minority adolescents (SMA) report higher rates of anxiety, self-harm, depression and suicide than heterosexual peers. These disparities appear to persist into adulthood and may worsen for certain subgroups, yet the mechanisms that drive these concerns remain poorly understood. Minority stress theory, the predominant model for understanding these disparities, posits that poorer outcomes are due to the stress of living in a violently homophobic and discriminatory culture. Although numerous studies report associations between minority stress and behavioural health in adolescence, no study has comprehensively examined how minority stress may change throughout the course of adolescence, nor how stress trajectories may predict health outcomes during this critical developmental period.

METHODS AND ANALYSIS

Between 15 May 2018 and 1 April 2019, we recruited a US national sample of diverse SMA (n=2558) age 14-17 through social media and respondent-driven sampling strategies. A subset of participants (n=1076) enrolled in the longitudinal component and will be followed each 6 months until 1 July 2022. Primary outcomes include symptoms of depression, anxiety and post-traumatic stress disorder; suicidality and self-harm and substance use. The key predictor is minority stress, operationalised as the Sexual Minority Adolescent Stress Inventory. We will use parallel cohort-sequential latent growth curve models to test study hypotheses within a developmental framework.

ETHICS AND DISSEMINATION

All participants provided assent to participate, and longitudinal participants provided informed consent at the first follow-up survey after reaching age 18. All study procedures were reviewed and approved by the University of Southern California Social-Behavioral Institutional Review Board, including a waiver of parental permission given the potential for harm due to unintentional 'outing' to a parent during the consent process. The final anonymous data set will be available on request, and research findings will be disseminated through academic channels and products tailored for the lay community.

Lifetime Prevalence and Sociodemographic Correlates of Multifactorial Discrimination Among Middle-Aged and Older Adult Men Who Have Sex with Men

This study describes multifactorial discrimination (discrimination attributed to multiple social identities) among middle-aged and older adult MSM. MSM aged 40+ years (N = 1,193) enrolled in the Multicenter AIDS Cohort Study completed behavioral surveys ascertaining experiences of discrimination and their social identity attributions. Non-proportional odds regressions assessed multifactorial discrimination by age, race/ethnicity, HIV status, and covariates. Twenty-seven percent of participants reported multifactorial discrimination. Adjusted models indicated that middle-aged men were more likely to report multifactorial discrimination compared to older adult men. Racial/ethnic minorities were more likely to report multifactorial discrimination compared to non-Hispanic white participants. These same patterns emerged among the sub-sample of participants living with HIV. To our knowledge, this is the first assessment of multifactorial discrimination in middle-aged and older MSM. Our findings support the deleterious association between multiple-marginalization and multifactorial discrimination. Multilevel interventions targeting interconnected experiences of stigma may improve the health of MSM in transition to older age.

Measuring the impact of legal recognition of same-sex marriage among sexual minority women

Reductions in structural stigma, such as gaining access to legalized same-sex marriage, is associated with positive psychological and physical health outcomes among sexual minority adults. However, these positive outcomes may be less robust among sexual minority women (SMW; e.g., lesbian, bisexual, queer) than sexual minority men and new measures are needed to develop a more nuanced understanding of the impact of affirming policies on the health and well-being of SMW. This study assessed the psychometric properties of measures developed to assess the psychosocial impacts of legalized same-sex marriage on the lives of SMW. Participants (N=446) completed an online survey assessing the psychosocial impact of legalized same-sex marriage in five domains: 1) personal impact, 2) stigma-related concerns, 3) couple impact, 4) LGBTQ community impact, and 5) political/social environment. Psychometric properties of the scales were examined using traditional and Rasch analyses. Personal, concerns, couple, and political/social environment scales demonstrated high internal consistency (α > 0.80), and acceptable levels of reliability even when scales reduced to five items each. The LGBTQ community scale demonstrated adequate internal consistency (α = 0.79) and could only be reduced to 9 items. These scales may be useful in future studies of SMW health and well-being.

Association between Discrimination and Depressive Symptoms Among 2,162 Lesbian, Gay, and Bisexual Adults in South Korea: Does Community Connectedness Modify the Association?

This study investigated the association between perceived discrimination and depressive symptoms among Korean lesbian, gay, and bisexual (LGB) individuals and explored the role of community connectedness in that association. We analyzed a nationwide cross-sectional survey of 2,162 LGB adults in Korea. Discrimination based on its types, including sexual orientation, over the past 12 months was classified into four categories: (1) 'never experienced discrimination,' experienced (2) 'only sexual orientation discrimination,' (3) 'any of the other types of discrimination,' and (4) 'both sexual orientation discrimination and any of the other types of discrimination.' Our findings suggest that there was a statistically significant association between 'only sexual orientation discrimination' and depressive symptoms among LGB individuals with a low-level of community connectedness, but not among those with a high-level. In the other two categories of discrimination, which included the other types of discrimination, the associations were statistically significant, regardless of the level of community connectedness.

Integrating Minority Stress Theory and the Interpersonal Theory of Suicide among Sexual Minority Youth Who Engage Crisis Services

OBJECTIVE

The present study sought to integrate minority stress theory (MST) and the interpersonal theory of suicide (ITS) to better understand high rates of suicide among sexual minority youth (SMY). To date, the ITS and MST have largely advanced independently from one another even though the research base for each theory contains gaps that the other theory may help fill.

METHOD

Using data from a national sample of 564 SMY (aged 12-24) recruited from an LGBTQ youth-focused suicide crisis prevention provider, we examined structural equation models to understand how perceived burdensomeness and thwarted belongingness mediate the relationship between minority stress and suicidal ideation and attempt.

RESULTS

Sexual minority stress was significantly associated with both perceived burdensomeness and thwarted belongingness in models predicting suicidal ideation and attempt. Moreover, minority stress had a direct effect on suicide attempt and an indirect effect on both suicidal ideation and suicide attempt through burdensomeness.

CONCLUSIONS

Given that minority stress is associated with greater thwarted belongingness, perceived burdensomeness, and suicide attempts, there should be greater demand for continuing education centered on sexual minority populations and population-specific services. Identifying burdensomeness as a minority stress-suicide mechanism highlights the potential gains of piloting recently developed burdensomeness interventions among SMY.

Effect of Discrimination on Presenteeism among Aging Workers in the United States: Moderated Mediation Effect of Positive and Negative Affect

This study aimed to examine how perceived everyday discrimination influences presenteeism and how conscientiousness moderates the relationship between discrimination and positive affect among older workers. Structural equation modeling (SEM) was used to examine the mediating effect. The moderated mediation model was examined by PROCESS. The results of the final SEM model showed that discrimination was directly positively associated with presenteeism. Furthermore, positive affect was significantly inversely correlated with discrimination and presenteeism. In addition, negative affect was significantly positively correlated with discrimination and presenteeism. The significant indirect effect between perceived everyday discrimination and positive affect was significantly mediated by positive and negative affect. In addition, the results of the moderated mediation model indicate that positive affect was more likely to be influenced by perceived everyday discrimination among older workers with less conscientiousness, as compared with those with greater conscientiousness. To enhance work outcomes of aging workers in the United States, managers should foster highly conscientious aging workers, award those who are hardworking and goal-oriented, and combine personal goals and organizational goals through bonuses, holidays, and benefits. Policymakers should be mindful of the negative impact of discrimination on presenteeism and should target lowly conscientious older workers.

Psychometric and Pragmatic Properties of Social Risk Screening Tools: A Systematic Review

CONTEXT

Health systems increasingly are exploring implementation of standardized social risk assessments. Implementation requires screening tools both with evidence of validity and reliability (psychometric properties) and that are low cost, easy to administer, readable, and brief (pragmatic properties). These properties for social risk assessment tools are not well understood and could help guide selection of assessment tools and future research.

EVIDENCE ACQUISITION

The systematic review was conducted during 2018 and included literature from PubMed and CINAHL published between 2000 and May 18, 2018. Included studies were based in the U.S., included tools that addressed at least 2 social risk factors (economic stability, education, social and community context, healthcare access, neighborhood and physical environment, or food), and were administered in a clinical setting. Manual literature searching was used to identify empirical uses of included screening tools. Data on psychometric and pragmatic properties of each tool were abstracted.

EVIDENCE SYNTHESIS

Review of 6,838 unique citations yielded 21 unique screening tools and 60 articles demonstrating empirical uses of the included screening tools. Data on psychometric properties were sparse, and few tools reported use of gold standard measurement development methods. Review of pragmatic properties indicated that tools were generally low cost, written for low-literacy populations, and easy to administer.

CONCLUSIONS

Multiple low-cost, low literacy tools are available for social risk screening in clinical settings, but psychometric data are very limited. More research is needed on clinic-based screening tool reliability and validity as these factors should influence both adoption and utility.

Measures of Racism, Sexism, Heterosexism, and Gender Binarism for Health Equity Research: From Structural Injustice to Embodied Harm-An Ecosocial Analysis

Racism. Sexism. Heterosexism. Gender binarism. Together, they comprise intimately harmful, distinct, and entangled societal systems of self-serving domination and privilege that structure the embodiment of health inequities. Guided by the ecosocial theory of disease distribution, I synthesize key features of the specified "isms" and provide a measurement schema, informed by research from both the Global North and the Global South. Metrics discussed include (a) structural, including explicit rules and laws, nonexplicit rules and laws, and area-based or institutional nonrule measures; and (b) individual-level (exposures and internalized) measures, including explicit self-report, implicit, and experimental. Recommendations include (a) expanding the use of structural measures to extend beyond the current primary emphasis on psychosocial individual-level measures; (b) analyzing exposure in relation to both life course and historical generation; (c) developing measures of anti-isms; and (d) developing terrestrially grounded measures that can reveal links between the structural drivers of unjust isms and their toll on environmental degradation, climate change, and health inequities.

Methodological Considerations for Advancing Research on the Health and Wellbeing of Sexual and Gender Minority Youth

Continued research with sexual and gender minority (SGM) youth is essential both to understand health disparities and to develop interventions targeting those disparities, but conducting rigorous, ethical research with these populations remains a substantial challenge. In addition to considerations for research with adolescents in general, such as utilizing developmentally appropriate measures and obtaining parental permission, factors unique to SGM youth must be addressed at every step of the research process. Defining the study population is complex, as is recruiting a sample once it is defined. Measurement is another challenge, given the paucity of measures developed for or validated with SGM samples. Key constructs, such as sexual orientation, gender identity, and family acceptance, are not amenable to randomization and involving minor participants' parents poses ethical concerns given the precarious home and safety situations that can arise from employing typical study procedures with youth who have a stigmatized identity. In this article, we examine some of these unique methodological challenges. Informed by theoretical and empirical literature, practical experience, and an ongoing dialogue with SGM youth themselves, we present a guide to best practices for ethical, productive research with SGM youth. By discussing existing approaches to studying SGM youth and suggesting innovative ways to approach the questions that remain, we hope to assist the research community in addressing methodological gaps to advance research on SGM youth in relation to families and schools.

Advancing Research on LGBTQ Microaggressions: A Psychometric Scoping Review of Measures

Understanding the nature and consequences of LGBTQ microaggressions is critical to fostering equity and wellbeing among sexual and gender minorities. Yet little guidance is available for researchers seeking psychometrically robust measures of subtle LGBTQ slights, invalidations, and insults. To address this gap, we conducted a scoping review of multi-item quantitative measures that included at least one question addressing LGBTQ microaggressions. This article reports the study characteristics and psychometric properties of 27 original measures we identified and their subsequent adaptations. The article concludes with an assessment of strengths and limitations of LGBTQ microaggression measurement, highlighting aspects of measurement innovation on which future researchers can build. As microaggressions remain a powerful and underexplored mechanism of sexual and gender minority oppression, this review will help to both advance methodological quality in this critical research area and enhance our understanding of how microaggressions manifest in the lives of LGBTQ individuals.

Development of the Sexual Minority Adolescent Stress Inventory

Although construct measurement is critical to explanatory research and intervention efforts, rigorous measure development remains a notable challenge. For example, though the primary theoretical model for understanding health disparities among sexual minority (e.g., lesbian, gay, bisexual) adolescents is minority stress theory, nearly all published studies of this population rely on minority stress measures with poor psychometric properties and development procedures. In response, we developed the Sexual Minority Adolescent Stress Inventory (SMASI) with N = 346 diverse adolescents ages 14–17, using a comprehensive approach to de novo measure development designed to produce a measure with desirable psychometric properties. After exploratory factor analysis on 102 candidate items informed by a modified Delphi process, we applied item response theory techniques to the remaining 72 items. Discrimination and difficulty parameters and item characteristic curves were estimated overall, within each of 12 initially derived factors, and across demographic subgroups. Two items were removed for excessive discrimination and three were removed following reliability analysis. The measure demonstrated configural and scalar invariance for gender and age; a three-item factor was excluded for demonstrating substantial differences by sexual identity and race/ethnicity. The final 64-item measure comprised 11 subscales and demonstrated excellent overall (α = 0.98), subscale (α range 0.75–0.96), and test–retest (scale r > 0.99; subscale r range 0.89–0.99) reliabilities. Subscales represented a mix of proximal and distal stressors, including domains of internalized homonegativity, identity management, intersectionality, and negative expectancies (proximal) and social marginalization, family rejection, homonegative climate, homonegative communication, negative disclosure experiences, religion, and work domains (distal). Thus, the SMASI development process illustrates a method to incorporate information from multiple sources, including item response theory models, to guide item selection in building a psychometrically sound measure. We posit that similar methods can be used to improve construct measurement across all areas of psychological research, particularly in areas where a strong theoretical framework exists but existing measures are limited.

A Systematic Review of the Psychometric Properties of Composite LGBT Prejudice and Discrimination Scales

Prejudice and discrimination against LGBT individuals is widespread and has been shown to have negative consequences for sexual and gender minority persons' physical and psychological wellbeing. A recent and problematic trend in the literature is to compositely measure prejudice toward and discrimination against LGBT persons. As such, a review of the psychometric properties of scales assessing, in a combinatory fashion, negative attitudes and/or behaviors toward LGBT persons is warranted. In the current study, 32 scales were identified, and their psychometric properties were evaluated. Most of the scales reviewed did not provide sufficient information regarding item development and refinement, scale dimensionality, scale score reliability, or validity. Properties of the reviewed scales are summarized, and recommendations for better measurement practice are articulated.

Criterion and Divergent Validity of the Sexual Minority Adolescent Stress Inventory

Sexual minority adolescents (SMA) consistently report health disparities compared to their heterosexual counterparts, yet the underlying mechanisms of these negative health outcomes remain unclear. The predominant explanatory model is the minority stress theory; however, this model was developed largely with adults, and no valid and comprehensive measure of minority stress has been developed for adolescents. The present study validated a newly developed instrument to measure minority stress among racially and ethnically diverse SMA. A sample of 346 SMA aged 14-17 was recruited and surveyed between February 2015 and July 2016. The focal measure of interest was the 64-item, 11-factor Sexual Minority Adolescent Stress Inventory (SMASI) developed in the initial phase of this study. Criterion validation measures included measures of depressive symptoms, suicidality and self-harm, youth problem behaviors, and substance use; the general Adolescent Stress Questionnaire (ASQ) was included as a measure of divergent validity. Analyses included Pearson and tetrachoric correlations to establish criterion and divergent validity and structural equation modeling to assess the explanatory utility of the SMASI relative to the ASQ. SMASI scores were significantly associated with all outcomes but only moderately associated with the ASQ (r = -0.13 to 0.51). Analyses revealed significant associations of a latent minority stress variable with both proximal and distal health outcomes beyond the variation explained by general stress. Results show that the SMASI is the first instrument to validly measure minority stress among SMA.

Validation Study of the Revised Version of the Scale of Prejudice Against Sexual and Gender Diversity in Brazil

In Brazil, there is a deficit of culturally adapted tools to assess prejudice against sexual and gender diversity with empirically demonstrable validity and reliability. Prejudice against non-heterosexual orientations is a strong problem within Brazilian culture and is particularly related to nonnormative expressions of gender. To address these issues, a scale was created. The objective of this article is to validate the revised version of this instrument developed for the specificities of Brazilian culture and establish its reliability. The revised version of Scale of Prejudice Against Sexual and Gender Diversity (PASGD) was completed by 8,184 undergraduate students from southern Brazil. Analysis was conducted using the item response theory (IRT) model for rating scale data, criterion validity, and confirmatory factor analysis (CFA). The scale showed good validity and reliability. The results indicate that the PASGD is a useful tool for assessing prejudice in the Brazilian context, adapted for the local Brazilian reality.

Spanish Validation of the Polymorphous Prejudice Scale in a Sample of University Students

The shortened version of the Polymorphous Prejudice Scale (PPS) analyzes new manifestations of prejudice toward gay men and lesbian women. Specifically, this instrument consists of 16 items distributed in four subscales: values gay progress, positive beliefs about gay men, positive beliefs about lesbian women, and resistance to heteronormative expectations. The aim of the current study is to add new evidence about the reliability and validity of the scale. The scale is administrated to 348 heterosexual university students from Spain with a mean age of 22.62 years (SD = 7.63). Reliability and factorial validity estimates are presented. A four-factor structure is supported using confirmatory factor analysis (short version). Our results can be useful in planning variables for intervention programs designed to foster the tolerance and normality of sexual diversity.
