Abstract(s)
Até o momento não encontrámos estudos para avaliar o efeito das crenças sexuais na
excitação sexual, ou a sua relação com dificuldades sexuais. Este estudo teve como objetivo
determinar a existência de uma relação entre as crenças sexuais, dificuldades sexuais e fatores
de excitação e inibição sexual numa amostra de respondentes de língua portuguesa. Também
foram identificadas as principais dificuldades sexuais relatados por homens e mulheres. As
propriedades psicométricas do Inventário de Excitação Sexual/Inibição Sexual para Mulheres
e Homens (SESII-W/M), e do Questionário de Crenças Sexuais Disfuncionais (SDBQ), foram
testadas. A amostra não-clínica de 1.878 homens e mulheres, com uma média de idade de
35,9 anos, cuja atividade sexual tinha sido exclusivamente com o sexo oposto (92,6%), foi
recrutada através da Internet. Os instrumentos incluíram informação sócio-demográfica, um
questionário sobre o estado do relacionamento, o SESII-W/M, o SDBQ e dificuldades sexuais
auto-relatadas. A análise dos dados considerou um nível de significância α < 0,05 e revelou
diferenças significativas em todos os testes aplicados. A dificuldade sexual mais
freqüentemente relatada referiu a "ejaculação precoce" nos homens e a "dificuldade em
conseguir o orgasmo" em mulheres. O SESII-W/M revelou-se um instrumento fraco, mas
aceitável. A fiabilidade de ambos os questionários sugeriu a exclusão de algumas dimensões.
Os resultados deste estudo indicam claramente uma associação entre as variáveis, embora
sejam necessários mais estudos para determinar a causa. A validação do SESII-W/M para o
português pode beneficiar estudos futuros de fatores de excitação e inibição sexual.
Up to date no studies can be found which evaluate the effect of sexual beliefs on sexual arousal, or their relationship with sexual difficulties. This study aimed to determine the existence of a relationship between sexual beliefs, sexual difficulties and factors of sexual excitation and inhibition in a Portuguese-speaking population. The main sexual difficulties reported by men and women were also identified. Psychometric properties of the Sexual Excitation/Sexual Inhibition Inventory for Women and Men (SESII-W/M), and of the Sexual Dysfunctional Beliefs Questionnaire (SDBQ), were tested. A non-clinical sample of 1,878 men and women, with a mean age of 35.9 years, whose sexual activity had been exclusively with the opposite sex (92.6%), was recruited through the Internet. Instruments included sociodemographic information, a relationship status questionnaire, the SESII-W/M, the SDBQ and self-reported sexual difficulties. Data analyses considered a significance level of α < 0.05 and revealed significant differences in all tests applied. The most frequently reported sexual difficulty referred to “premature ejaculation” in men and “difficulty in experiencing orgasm” in women. The SESII-W/M model fit proved to be weak, but acceptable. Reliability of both questionnaires suggested the exclusion of some dimensions. The findings in this study clearly indicate an association between variables, although further investigation is needed in order to determine causation. Validation of the SESII-W/M into Portuguese could benefit future studies regarding factors of sexual excitation and inhibition.
