Several studies have shown that dyadic coping, that is, the way couples cope with stress, plays a unique role in intimate relationships. The aim of this study is to validate the Portuguese version of the Dyadic Coping Inventory (DCI; Bodenmann, 2008 ) by analyzing the factorial structure and psychometric properties of the DCI as well as its convergent and criterion validity. A multigroup confirmatory factor analysis was conducted in a community sample of 605 participants living in Portugal who had been in a close relationship for at least 2 years. The findings support the hypothesized five-factor structure for the DCI and self- and other-perception, and a two-factor structure for joint dyadic coping. The psychometric properties of the DCI and its criterion validity with other relationship measures (RAS and B-SRQ) were good. These results add an important contribution to the determination of the criterion validity of the DCI with measures of other crucial domains of couples’ functioning (Shared Meaning, Conflict Processes, and Quality of Sexuality, Passion, and Romance); to the cross-cultural validation of the DCI; and to the demonstration that negative DC has a significant effect on intimate relationship processes, which contradicts the findings of previous studies. Moreover, it provides an additional tool for working with Portuguese-speaking individuals all over the world.

The DSM-5 Section III proposes a hybrid dimensional-categorical model of conceptualizing personality and its disorders that includes assessment of impairments in personality functioning (criterion A) and maladaptive personality traits (criterion B). The Personality Inventory for the DSM-5 is a new dimensional tool, composed of 220 items organized into 25 facets that delineate five higher order domains of clinically relevant personality differences, and was developed to operationalize the DSM-5 model of pathological personality traits. The current studies address the internal consistency (study 1), the test-retest reliability (study 2) and the criterion validity (studies 3 and 4) of the Portuguese version of the PID-5 in samples of native speaking psychology students. Results indicated good internal consistency reliabilities and good temporal stability reliabilities for the majority of the PID-5 traits. The correlational pattern of the PID-5 traits with two measures of personality was in accordance with theoretical expectations and showed its concurrent validity.

The fibromyalgia syndrome (FM) is a chronic widespread pain condition whose etiology remains unknown and no treatment has satisfactory levels of success. A metaanalysis has identified a distinct Minnesota Multiphasic Personality Inventory-2 (MMPI-2) clinical profile between FM female patients and healthy controls, and differences between FM and other chronic pain condition with clear etiology have also been found. However, heterogeneity in this population has been suggested in several studies. We aim to assess clinical aspects in FM patients, based on personality psychopathology characteristics, in order to explore heterogeneity and the existence of core common aspects. In this cross-sectional study, a relatively homogeneous sample of 56 female FM patients (Mage = 45.95, SDage = 9.39) was assessed through MMPI-2. A K-Means cluster analysis identified two clusters, one (n = 24) with clinically significant levels in Negative Emotionality and Introversion scales. Subsequent MANOVAs identified important features of this cluster on several MMPI-2 dimensions. Moreover, several dimensions are clinically elevated in both clusters. In conclusion, the combination of psychopathological negative emotionality, interpersonal isolation, and low hedonic capacity, in a group of patients, has implications for the daily living and treatment of FM patients, and several core aspects of FM need to be addressed.

This study aimed to evaluate the relation of disability and physical and mental health status with potentially traumatic life events (PTLE) before the onset of fibromyalgia in women diagnosed with this syndrome. We also investigated causal attribution of fibromyalgia to a triggering event, physical or psychological in nature, and its relation with the health measures and the adverse life events. The impact of fibromyalgia, physical and mental health status, pain, PTLE in childhood and not in childhood, and causal attribution were assessed in a sample of 50 women with fibromyalgia, aged 25-70 (M = 46.96; SD = 10.96). There were no statistically significant relations between the health measures (disability, physical and mental health, and pain) and the PTLE. The predominant attribution was to a physical event. There were no significant differences neither in the health measures across causal attribution status (Pillai's Trace = 0.193; F(8,90) = 1.200; p = .308; η2 par = .096) nor in the PTLE not in childhood (F(2,47) = 1.063; p = .354; η2 par = .043). There were significant differences across causal attribution status in the PTLE in childhood (F(2,47) = 3.590; p = .035; η2 par = .133), specifically between the group that made a psychological attribution and the group that made no attribution (C.I. 95%) 0.1805; 14.0468; (p = .043), with the former having a higher score of PTLE in childhood. The results raise questions about the importance of psychological aspects in the appraisal of the adverse events and its possible relation to the psychological functioning in women with fibromyalgia.

ResumoA satisfação sexual é um indicador importante da saúde sexual, contudo, a sua defi nição não é consensual. A Global Measure of Sexual Satisfaction (GMSEX) é um instrumento que avalia a satisfação sexual global no contexto de uma relação íntima. Pretendeu-se avaliar o comportamento psicométrico deste instrumento em três amostras distintas da população portuguesa, constituídas por participantes comprometidos em relações de coabitação: duas amostras presenciais designadas por "grupo normativo" sem diagnóstico e percepção de problemas sexuais (n = 291), "grupo clínico" com problemas sexuais (n =84), e uma amostra online (n = 760). Confi rmou-se a estrutura unifactorial da escala, verifi cando-se uma adequada fi abilidade e validade do instrumento. Palavras-chave: Satisfação sexual, saúde sexual, coabitação, processo de validação. AbstractSexual satisfaction is an important indicator of sexual health, however, its defi nition is not consensual. Lawrence and Byers (1995) developed a conceptual model of sexual satisfaction for people in committed relationships and, within this model, the authors developed the Global Measure of Sexual Satisfaction (GMSEX) which assesses global sexual satisfaction in the context of an intimate relationship. In the present study we aimed to adapt and assess the psychometric properties of this scale with three distinct samples from the Portuguese population in cohabitation relationships. One was designated as "normative group" with no diagnosis and perception of sexual problems (n = 291), another called "clinical group", whose participants presented sexual problems (n = 84), and an "online" sample of participants with and without perception of sexual problems (n = 760). The scale proved to have a single factor structure as well as good reliability and validity.

In cluster analysis, it can be useful to interpret the partition built from the data in the light of external categorical variables which were not directly involved to cluster the data. An approach is proposed in the model-based clustering context to select a model and a number of clusters which both fit the data well and take advantage of the potential illustrative ability of the external variables. This approach makes use of the integrated joint likelihood of the data and the partitions at hand, namely the model-based partition and the partitions associated to the external variables. It is noteworthy that each mixture model is fitted by the maximum likelihood methodology to the data, excluding the external variables which are used to select a relevant mixture model only. Numerical experiments illustrate the promising behaviour of the derived criterion.
