Abstract(s)
A importância crescente da expressão sexual entre as pessoas idosas exige uma compreensão mais abrangente do processo de envelhecimento sexual. O objetivo deste estudo foi validar a escala Successful Sexual Aging Scale (SSAS; Štulhofer, 2025) para a população portuguesa. Usando uma amostra de conveniência de 311 portugueses com mais de 60 anos (M_age=71,8; DP=9,1; 211 mulheres e 100 homens), validamos uma medida de 9 itens sobre envelhecimento sexual bem-sucedido. A Análise Fatorial Confirmatória (AFC) realizada na amostra portuguesa apoiou a estrutura tridimensional da Successful Sexual Aging Scale (SSAS; Stulhofer, 2025) que reflete dois processos internos (aceitação e adaptação às mudanças relacionadas ao envelhecimento) e um processo externo (oportunidades de expressão sexual). Um bom ajuste foi obtido após uma covariância de erro entre dois itens logicamente sobrepostos. A invariância de medida do SSAS foi examinada entre seniores com parceiro (n = 188) e seniores sem parceiro (n = 120) usando AFC multigrupo. A invariância configural e métrica foi suportada, indicando que a escala avalia o construto de forma semelhante entre os grupos nesses níveis. No entanto, a invariância escalar não foi estabelecida, sugerindo que o SSAS não mede o construto de forma idêntica em ambos os grupos. Isso implica que a comparação direta dos scores do SSAS entre indivíduos parceiros e não parceiros pode não ser apropriada. Globalmente, a versão portuguesa do SSAS apresentou boas propriedades psicométricas e pode ser considerada um instrumento válido para avaliar o envelhecimento bem-sucedido na população idosa portuguesa
The increasing importance of sexual expression among older people calls for a more comprehensive understanding of the process of sexual aging. The purpose of this study was to validate the Successful Sexual Aging Scale (SSAS; Štulhofer, 2025) for the Portuguese population. Using a convenience sample of 211 women and 100 men aged 60 + years (M_age=71.8; SD=9.1), we validated a 9-item measure of successful sexual aging. The confirmatory Factor Analysis (CFA) supported the 3-Dimensional SSAS, which reflects two internal processes (acceptance of and adaptation to aging-related changes) and one external process (opportunities for sexual expression). A good fit was obtained after an error covariance between two logically overlapping items. Measurement invariance of the SSAS was examined across partnered (n = 188) and non-partnered (n = 120) older adults using multi-group CFA. Configural and metric invariance were supported, indicating that the scale assesses the construct similarly across groups at these levels. However, scalar invariance was not established, suggesting that the SSAS does not measure the construct identically in both groups. This implies that direct comparison of SSAS scores between partnered and non-partnered individuals may not be appropriate. Overall, the SSAS Portuguese version showed good psychometric properties and can be considered a valid instrument for assessing successful aging in the Portuguese older adult population.
