Validation of the Mental Illness Sexual Stigma Questionnaire (MISS-Q) in a sample of Brazilian adults in psychiatric care
Abstract
Objective: We evaluated the psychometric properties of a new instrument "Mental Illness Sexual Stigma Questionnaire" (MISS-Q).
Methods: We interviewed 641 sexually active adults (ages 18-80) attending public outpatient psychiatric clinics in Rio de Janeiro about their stigma experiences.
Results: Nine factors were extracted through exploratory factor analysis (EFA) and labeled: 'individual discrimination by others'; 'staff willingness to talk about sexuality'; 'staff and family prohibitions'; 'sexual devaluation of self'; 'perceived attractiveness'; 'mental illness concealment'; 'perceived sexual role competence'; 'withdrawal'; and 'locus of social-sexual control'. 'Withdrawal' and 'locus of social-sexual control' showed poor psychometric properties and were excluded from further analysis. The remaining seven factors had high factorial loadings (.39 to .86), varying from sufficient to optimal reliability (Ordinal α ranged from .57 to .88), and good convergent and discriminant validity.
Conclusions: The resulting MISS-Q is the first instrument assessing mental illness sexual stigma with demonstrated psychometric properties. It may prove useful in reducing stigma, protecting sexual health, and promoting recovery.
Objetivo: Avaliamos as propriedades psicométricas de um novo instrumento “Mental Illness Sexual Stigma Questionnaire” (MISS-Q; Questionário de Estigma Sexual na Doença Mental).
Métodos: Entrevistamos 641 adultos sexualmente ativos (18 a 80 anos), frequentando clínicas psiquiátricas ambulatoriais públicas no Rio de Janeiro sobre suas experiências de estigma.
Resultados: Foram extraídos nove fatores por meio da análise exploratória fatorial e rotulados: ‘discriminação individual por parte de outros’; ‘disposição pessoal para falar sobre sexualidade’; proibições pessoais e familiares; ‘desvalorização sexual de si mesmo’; ‘percepção de atratividade’; ‘dissimulação da doença mental’; ‘percepção da competência de papel sexual’; ‘retirada’; e ‘locus de sociosexual ao controle’. ‘Retirada’ e ‘locus de controle social-sexual’ mostraram propriedades psicométricas fracas e foram excluídos da análise posterior. Os sete fatores restantes tinham altas cargas fatoriais (0,39 a 0,86), variando de suficiente até confiabilidade ótima (Ordinal α variou de ,57 a ,88), e boa validade convergente e discriminante.
Conclusões: O resultante MISS-Q é o primeiro instrumento que avalia o estigma sexual da doença mental com propriedades psicométricas demonstradas. Pode ser útil na redução do estigma, proteção da saúde sexual e promoção à recuperação.
Keywords: Stigma; psychometric assessment; severe mental illness; sexual and romantic relationships.
