- A cross-national investigation of psychosis-like experiences in five European countries included in the E-CLECTIC study: Psychometric challenges in studying their measurementPublication . Siddi, Sara; Ochoa, Susana; Larøi, Frank; Lincoln, Tania M.; Schlier, Bjorn; Zaytseva, Yuliya; Laloyaux, Julien; Kozáková, Eva; Cella, Matteo; Ntouros, Evangelos; Bozikas, Vasileios; Rocha, Nuno; Gawęda, Łukasz; Rocha, Susana Aguiar; Preti, AntonioPsychotic-like experiences (PLEs) are subtle, subclinical perturbations of perceptions and thoughts and are common in the general population. Their characterisation and unidimensionality are still debated. This study was conducted by the Electronic–halluCinations-Like Experiences Cross-culTural International Consortium (E-CLECTIC) and aimed at measuring the Community Assessment of Psychic Experiences (CAPE) factorial structure across five European countries (Belgium; Czech Republic, Germany; Greece, and Spain) and testing the adequacy of the unidimensional polytomous Rasch model of the tool via Partial Credit Model (PCM) of the CAPE to detect people with a high risk for developing psychosis. The sample included 1461 participants from the general population. The factorial analysis confirmed the best fit for the bifactor implementation of the three-factor model, including the positive, negative and depressive dimensions and a general factor. Moreover, the unidimensional polytomous Rasch analysis confirmed that CAPE responses reflected one underlying psychosis proneness. The study proved that the CAPE measures a single latent dimension of psychosis-proneness. The CAPE might help locate and estimate psychosis risk and can be used as a screening tool in primary care settings/education settings.
- The relationship between childhood abuse and adult attachment styles: the mediator role of sensory over-responsivityPublication . Silva, Alexandra; Ferreira, Simão; Pinto, Élia Silva; Rocha, Susana Aguiar; Rocha, Nuno BarbosaChild abuse portrays health and well-being issues that can last for several years, including altering interpersonal behavior. Evidence has shown that these early negative experiences may cause changes in sensory modulation. This study aimed to understand if sensory over-responsivity (SOR) plays an important role in mediating the association between childhood abuse (emotional abuse, emotional neglect, sexual abuse, physical abuse, physical neglect) and attachment-related anxiety or avoidance in adult romantic relationships. An online survey was conducted to examine these associations in a Portuguese community sample (N = 500) aged 18–62 years. The presented mediation models shown a higher mediation percentage for attachment-related anxiety rather than avoidance. All variables predicted the mediator, except sexual abuse which did not predict the overall model when the mediator was included. Our results have implications for individual treatment approaches regarding child abuse victims and can certainly influence intervention strategies.
