Abstract(s)
A saúde sexual é uma dimensão essencial do bem-estar das pessoas e constitui um importante domínio da saúde pública. Jovens, especialmente estudantes do ensino superior, estão frequentemente expostos a comportamentos sexuais de risco que favorecem a transmissão de infeções sexualmente transmissíveis, gravidez não planeada, violência sexual e problemas de saúde mental. Neste contexto, instrumentos válidos e culturalmente adaptados são fundamentais para avaliar estes comportamentos e orientar estratégias de prevenção e intervenção.
Este estudo de Pós-Doutoramento teve como objetivo traduzir, adaptar culturalmente e validar a Sexual Risk Behaviors Scale para o contexto português, originando a versão SRBS-PT. A adaptação visou garantir a equivalência conceptual, linguística e cultural da escala, tornando-a aplicável à realidade dos estudantes do ensino superior em Portugal.
Seguindo as diretrizes da International Society for Pharmacoeconomics and Outcomes Research e a checklist COSMIN, foi conduzido um estudo metodológico transversal. O processo de adaptação incluiu: tradução dupla independente, retrotradução, reconciliação, avaliação por peritos e pré-teste cognitivo com 10 estudantes. A versão final foi aplicada online a estudantes de cursos da área da saúde de uma instituição de ensino superior.
Participaram 68 estudantes com idades entre 18 e 25 anos, que cumpriram os critérios de inclusão (início da vida sexual e atividade sexual nos últimos 30 dias). A maioria era do sexo feminino, solteira e heterossexual, predominando estudantes de Enfermagem.
A validade estrutural foi inicialmente explorada por análise de componentes principais, que revelou uma estrutura unidimensional, com um único fator a explicar 63,75% da variância. A rotação Varimax não foi aplicada, dado que apenas um fator foi extraído.
Posteriormente, uma análise fatorial confirmatória confirmou o ajustamento do modelo unidimensional, com índices muito satisfatórios (CFI = .992; TLI = .987; SRMR = .053) e um alfa de Cronbach de .881. As correlações item-total corrigidas variaram entre .438 e .847. A validade de construto foi testada com a SA-SH-PT, tendo-se verificado uma correlação fraca (r = .032), o que sugere validade discriminante entre os dois instrumentos.
A SRBS-PT demonstrou propriedades psicométricas adequadas e revelou-se culturalmente apropriada para estudantes portugueses da área da saúde. Para além da investigação, poderá ser útil em contextos educativos e clínicos, contribuindo para a promoção da literacia em saúde sexual e para a implementação de políticas públicas informadas. Estudos futuros deverão ampliar a amostra e testar a aplicabilidade da escala em diferentes grupos populacionais.
Sexual health is a key dimension of people well-being and represents a crucial area in public health. Young people, particularly higher education students, are often exposed to risky sexual behaviors that increase vulnerability to sexually transmitted infections, unplanned pregnancies, sexual violence, and mental health issues. In this context, valid and culturally adapted instruments are essential for assessing these behaviors and guiding prevention and intervention strategies. This Postdoctoral study aimed to translate, culturally adapt, and validate the Sexual Risk Behaviors Scale for the Portuguese context, resulting in the SRBS-PT version. The adaptation process sought to ensure conceptual, linguistic, and cultural equivalence, making the instrument suitable for the reality of Portuguese higher education students. Following the guidelines of the International Society for Pharmacoeconomics and Outcomes Research and the COSMIN checklist, a cross-sectional methodological validation study was conducted. The adaptation process included independent dual translation, back-translation, reconciliation, expert panel content review, and cognitive pre-testing with 10 students. The final version was administered online to students enrolled in health-related programs at a Portuguese higher education institution. A total of 68 students aged 18 to 25 participated, meeting the inclusion criteria (sexual debut and sexual activity within the past 30 days). Most participants were female, single, and heterosexual, with a predominance of nursing students. Structural validity was first explored through principal component analysis, which revealed a unidimensional structure, with a single factor explaining 63.75% of the total variance. The Varimax rotation was not applied, as only one factor was extracted. A subsequent confirmatory factor analysis confirmed the adequacy of the unidimensional model, with excellent fit indices (CFI = .992; TLI = .987; SRMR = .053) and a Cronbach’s alpha of .881. Corrected item-total correlations ranged from .438 to .847. Criterion validity was examined using the SA-SH-PT, yielding a very weak correlation (r = .032), suggesting discriminant validity between the two instruments. The SRBS-PT demonstrated adequate psychometric properties and was culturally appropriate for Portuguese health sciences students. Beyond its use in research, it may be a valuable tool in educational and clinical settings, supporting the promotion of sexual health literacy and the implementation of evidence-based public health policies. Future studies should expand the sample size and explore the applicability of the scale in different demographic and sociocultural groups.
