The COVID-19 pandemic affected the mental health of people, especially adolescents. Although the negative impact of the pandemic has been described, studies on the role of protective factors in this population remain scarce. Using a mediation model approach, we examined the relationship between emotional well-being, self-compassion, and basic psychological needs in adolescents at school during the pandemic. Adolescents attending schools in northern Portugal (1092; 511 boys and 581 girls; aged 12 to 18 years) completed the Positive and Negative Affect Schedule, the Self-Compassion Scale – Youth Version, and the Adolescents’ Basic Psychological Needs at School Scale. Boys reported higher positive affect, emotional well-being, and self-compassion than girls. A significant positive association between adolescents’ self-compassion and satisfaction of basic psychological needs at school was mediated by emotional well-being. The findings highlight the protective role of emotional well-being, self-compassion, and basic psychological needs during challenging times, such as the COVID-19 pandemic.

This study examines the mediating role of repetitive negative thinking in the relationship between generalized anxiety symptoms and life satisfaction. A web survey was administered to 857 participants (365 men) who filled out a sociodemographic questionnaire, the Generalized Anxiety Disorder-7, the Persistent and Intrusive Negative Thoughts Scale, and the Satisfaction with Life Scale. Then, participants were divided into four groups according to levels of symptomatology. The results showed that scores for repetitive negative thinking increased due to the severity of generalized anxiety symptoms. For life satisfaction, individuals without generalized anxiety symptoms scored significantly higher than individuals with generalized anxiety symptoms. Furthermore, repetitive negative thinking mediates and explains over 54% of the relationship between generalized anxiety symptoms and life satisfaction when controlling for age, sex, clinical diagnosis, and current psychiatric medication. Overall, the current findings highlight the central role of repetitive negative thinking in the relationship between generalized anxiety symptoms and life satisfaction and reinforce a transdiagnostic process in the maintenance of anxiety symptomatology and well-being impairment.

Several studies demonstrated that intimate bidirectional violence (BV) is more common than unidirectional IPV. However, little is known about the phenomenon of BV during COVID-19 lockdowns. The present study focuses on BV during the second lockdown in Portugal to characterize the BV rates in an online sample from the community and identify the main psychosocial correlates associated with BV. Three hundred and thirty-six Portuguese adults, with a mean age of 35.02 years (SD = 11.67; 18–68 years), participated in this study. In addition to a sociodemographic questionnaire, IPV (victimization and perpetration), psychological distress, COVID-19-related anxiety, COVID-19 fear, and life satisfaction measures were used. BV (31.3%) emerged as the most reported pattern of violence. The BV group scored higher on psychological distress and depression than the nonviolence group. Being married/living in cohabitation, having a high level of education, working on the front line (during the COVID-19 pandemic), and having psychological distress emerged as important predictors of BV. Results emphasized the role of psychosocial dimensions, particularly marital status/cohabitation and educational levels, as relevant risk factors for BV during a worldwide crisis event. The assessment, prevention, and intervention of IPV should consider the possibility of BV, providing a response congruent with its specificities.

Although different studies have found that exposure to intimate partner violence (IPV) in childhood is linked to IPV perpetration in adulthood, others have revealed null effects. 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 between exposure to IPV in childhood and IPV perpetration in adulthood and verify whether this relationship was mediated by aggression and its components (verbal and physical aggression, anger, and hostility). Two hundred and forty five men convicted of domestic violence, from prison and community, were recruited. Correlation analysis revealed a positive link between exposure to IPV in childhood, aggression traits, and specifically physical aggression, and IPV frequency in adulthood. Overall aggression traits and physical aggression traits were statistically significant mediator variables explaining almost 15% of the overall effect of exposure to IPV in childhood on overall IPV frequency in adulthood. These findings unravel the role of aggression in the perpetration of physical and total IPV, claiming our attention to the need to include strategies to increase emotion regulation and problem-solving strategies in intervention programs.

More research is needed to understand the factors that contribute to low academic achievement in institutionalized children. The aim of this study was to investigate the relationship between cognitive and emotion regulation skills and academic performance, by comparing institutionalized and noninstitutionalized Portuguese children. The sample comprised 94 participants (46 institutional-ized (22 boys) and 48 noninstitutionalized (23 boys) children), aged between 6 and 10 years, matched for age and sex. We used Raven's Colored Progressive Matrices (RCPM) to measure cognitive abilities. Emotional regulation and negative lability were assessed using the Emotion Regulation Questionnaire (ERC). Academic performance was assessed with the Competence Academic Scale (CAS) of the Por-tuguese version of the Social Skills Rating System-Teacher Form (SSRS-T). Institutionalized children exhibited poorer academic performance than their noninstitutionalized counterparts (effect size, η 2 = 0.174). Cognitive ability (β = 0.28) and negative lability (β = −0.28) were significant predictors of academic performance. In addition to institutionalization, cognitive ability, and the challenges of managing negative emotions may contribute to the observed differences in academic performance. Interventions aimed at fostering cognitive and emotional competencies may play a protective role for institutionalized children facing academic and social difficulties.

Background Prison sentences are a particular type of penalty that aim to reintegrate individuals into society. Nonetheless, research suggests that prison sentences have a null or a criminogenic effect on recidivism and a critical impact on inmates’ mental health, negatively interfering with their successful reintegration into society and recidivism. Prevalence rates of mental health disorders among individuals who commit crimes are high, but little is known about how incarceration perpetuates and/or worsens mental health symptoms. In the Portuguese context, no studies focused on understanding the impact of imprisonment on prisoners’ mental health. Thus, this project aims to understand incarceration’s mental health and well-being impact on male and female individuals convicted to prison, both while incarcerated and after release. Methods The study will follow a quantitative cross-sectional design of male and female individuals in prison and parole, aiming to assess different samples at different moments of the prison sentence. It will also follow a longitudinal design in a subsample of male and female individuals sentenced to prison and on parole who will be followed for one year. Discussion This study intends to have a meaningful impact on the understanding of imprisonment effects, giving important clues for developing and implementing evidence-based prevention and intervention strategies to address prisoners’ and ex-prisoners’ mental health and improve their ability to successfully reintegrate into society and reduce recidivism.

The benefits of sexuality for physical and psychological health throughout life, including in old age, are widely reported in the literature. However, in Portugal, little is known about the attitude of health professionals toward sexuality. Therefore, the aim of this study is to investigate general attitudes toward sexuality and toward sexuality in older people among Portuguese health professionals and students. A sample of 424 different health professionals of both sexes completed a questionnaire that included sociodemo-graphic characteristics questions and general (Sexual Attitudes Scale-SAS) and aging (Aging Sexual Knowledge and Attitudes Scale-ASKAS) sexual attitudes scales. The results showed that physicians are the ones who reveal the greatest openness toward birth control issues. Regarding attitudes toward sexuality in older people, physicians and nurses are the ones with the most knowledge about this subject; and physical therapists are the ones with less permissive attitudes in this area. It is expected that this work will contribute to a reflection on the training of healthcare professionals regarding human sexuality, especially sexuality among older people.

The current study aimed at translating and validating the TSMQ into Portuguese-European (TSMQ-PT) and to investigate its psychometric properties. Three online studies were conducted with independent samples collected between September 2020 and March 2022. Study 1 tested the exploratory factorial structure (N = 325; 206 women); Study 2 explored the confirmatory factorial structure and construct validity (N = 450; 230 women); and Study 3 examined the temporal stability of the TSMQ-PT (N = 30; 15 women). Participants completed the TSMQ-PT for all three studies. In study 2, further completed the Sexual Compulsivity Scale, the Sexual Sensation Seeking Scale, and the Sexual Desire Inventory. Data revealed that the TSMQ-PT yielded a four-structure model, (i.e., Sexually Oriented, Comparison with Others, Seeking for Sexual Encounters, and Importance of Sex) comprising 13 items, with seven additional items for assessing existence and number of sexual partners, and frequency of sexual behaviors. The TSMQ-PT achieved good internal consistency levels (McDonald's omega ranged from .71 to .89) and construct validity, and temporal stability over 10-11 months (values ranged from .80 to .87) supporting the trait-dimension of sexual motivation. Current findings support a brief, valid, and reliable self-report instrument for assessing sexual motivation in the Portuguese context.

Background: Sexual satisfaction is a complex, multifaceted, and broad concept that is influenced by several factors. The minority stress theory posits that sexual and gender minorities are at a particular risk for stress due to stigma and discrimination at the structural, interpersonal, and individual levels. The aim of this systematic review and meta-analysis was to evaluate and compare the sexual satisfaction between lesbian (LW) and heterosexual (HSW) cisgender women. Methods: A systematic review and meta-analysis were conducted. We searched the PubMed, Scopus, Science Direct, Websci, Proquest, and Wiley online databases from 1 January 2013 to 10 March 2023 to identify the published observational studies on sexual satisfaction in women according to their sexual orientation. The risk of bias in the selected studies was assessed using the JBI critical appraisal checklist for the analytical cross-sectional studies. Results: A total of 11 studies and 44,939 women were included. LW reported having orgasms during a sexual relationship more frequently than HSW, OR = 1.98 (95% CI 1.73, 2.27). In the same direction, the frequency of women reporting "no or rarely" for having orgasms during their sexual relationships was significantly lower in the LW than the HSW, OR = 0.55 (95% CI 0.45, 0.66). The percentage of the LW who reported having sexual intercourse at least once a week was significantly lower than that of the HSW, OR = 0.57 for LW (95% CI 0.49, 0.67). Conclusions: Our review showed that cisgender lesbian women reached orgasm during sexual relations more often than cisgender heterosexual women. These findings have implications for gender and sexual minority health and healthcare optimization.

Repetitive negative thinking is a cognitive dimension of the onset and maintenance of psychopathology, and increased levels of psychopathology have been observed during COVID-19 lockdowns. The role of fear of COVID-19 and COVID-19 anxiety has been poorly explored in terms of psychopathology during lockdowns due to the pandemic crisis. This study examines the mediating role of fear of COVID-19 and COVID-19 anxiety in the relationship between repetitive negative thinking and psychopathology during the second lockdown in Portugal. Participants completed a web survey that included a sociodemographic questionnaire, the Fear of COVID-19 Scale, the COVID-19 Anxiety Scale, the Persistent and Intrusive Negative Thoughts Scale, and the Depression, Anxiety, and Stress Scale − 21. The results showed a positive and significant correlation between all variables and identified fear of COVID-19 and COVID-19 anxiety as significant mediators in the relationship between repetitive negative thinking and psychopathology during the second lockdown in Portugal, after controlling for being isolated, being infected, and working in first line response of COVID-19. Overall, the current findings highlight the role of cognitive dimensions such as anxiety and fear in the context of COVID-19, nearly a year after the pandemic outbreak and after the release of a vaccine. Mental health programs should consider improving coping strategies for emotion regulation, particularly fear and anxiety, during major catastrophic health-related events.
