Psychometric Properties and Gender Invariance of the Portuguese (European) Version of the Aging Sexual Knowledge and Attitudes Scale

In this sense, analysing people's sexual knowledge and attitudes towards older people is a challenge for theory and practice. The aim of this study is to translate and validate the Aging Sexual Knowledge and Attitudes Scale (ASKAS) for the Portuguese population. A sample of 994 Portuguese adults (70.9% women, n = 705) completed the ASKAS-PT a…

Previous research has also found that some factors might mediate the relationship between exposure to IPV in childhood and later IPV perpetration. As far as we know, no studies examined the role of aggression in this relationship. This study aimed to analyze the link bet…

Cognitive-Emotional Predictors of Sexual Functioning in Lesbians, Gays, and Heterosexuals

Research on male sexual desire and satisfaction according to sexual orientation remains insufficient. An online survey was fulfilled by 415 men (142 gay; 273 heterosexual), and participants completed the SDI-2 and the GMSEX. Main findings suggested that gay men scored significantly higher on both solitary sexual desire and attractive person-related dyadic sexual desire subscales, but not on a partner-related dyadic sexual desire subscale, compare…

The Activation of Incompetence Schemas in Response to Negative Sexual Events in Heterosexual and Lesbian Women
Personality traits and dysfunctional sexual beliefs have been described as vulnerability factors for sexual dysfunction in women, and have also been proposed as dispositional variables for the activation of incompetence schemas in response to negative sexual events. However, no study has tested the role of personality traits and dysfunctional sexual beliefs in the activation of incompetence schemas. The current study aimed to assess the moderator…
