- ItemDoes Professional Identity Mediate the Relationship between Emotional Labour and Work Engagement? A study with Portuguese police officers(Sage, 2024-11-19) Carvalho, Carla M. Santos de; Pinto, Ana; Oliveira, Soraia; Graça, Andreia; Moura, Rui Coelho dePolice officers work under demanding emotional, psychological and physical circumstances while interacting with victims, criminals and colleagues. They are faced daily with emotional demands to express positive emotions and, at the same time, are required to suppress negative emotions. Consequently, this influences the emotional regulation strategies (i.e., deep- or surface-acting) they choose to use, which impacts their professional identity and work engagement. We conducted a study to understand whether professional identity mediates the relationship between emotional labour (demands and strategies) and work engagement in a sample of Portuguese police officers. For this purpose, we used a set of four self-administered questionnaires: Emotional Work Requirements Scale (EWRS), Emotional Labour Scale (ELS), Social Identity Scale (SIS) and Utrecht Work Engagement Scale (UWES). 924 police officers from the Portuguese Public Security Police (PSP) participated voluntarily. Our results show that there is a mediating effect of professional identity on the relationship between surface-acting strategies, positive emotion expression and negative emotion suppression demands, and work engagement. Professional identity fully mediates the relationship between negative emotion suppression demands and work engagement. Nevertheless, there seems to be no mediating effect of professional identity on the relationship between deep-acting strategies and emotional variety and intensity demands, and work engagement. To the best of our knowledge, no other study has analysed the aforementioned variables in Portuguese police forces. Meaning that our study is ground-breaking, with clear implications. Further research is needed on this subject to understand better the relationship among these variables in the police population.
- ItemMeasuring Self-disgust in Adolescence: adaptation and validation of a new instrument for the Portuguese adolescent population(Taylor & Francis, 2023-06-02) Carreiras, Diogo; Guilherme, Mariana; Cunha, Marina; Castilho, PaulaSelf-disgust is a complex emotion related to feeling aversion or revulsion about internal and personal physical attributes, personality, functioning and behaviours. The aim of the present study was to adapt, validate and examine the psychometric properties of the Multidimensional Self-Disgust Scale, in a sample of Portuguese adolescents (MSDS-A). Participants were 540 adolescents (n = 308females, 57%), with ages between 13 and 18 years. Data were analysed through SPSS and MPLUS was used to perform a Confirmatory Factor Analysis (CFA). Self-report questionnaires were used to assess several indicators of psychopathology and self-compassion. Results from the CFA showed that a 4-factor model with a second order factor presented good fit indices. The full scale and its factors showed good internal consistency, adequate temporal stability, and good convergent, divergent and incremental validity. The MSDS-A seems a valid measure to assess self-disgust in adolescents, with important implications to clinical context and research.
- ItemEveryday Discrimination Scale: dimensionality in a Portuguese community sample and specific versions for sexual and gender minority(Springer, 2023-09-18) Seabra, Daniel; Gato, Jorge; Petrocchi, Nicola; Carreiras, Diogo; Azevedo, Julieta; Martins, Luís; Salvador, Maria do CéuPerceived everyday discrimination is a transversal phenomenon with a negative impact on people’s health. This study aimed to explore the factor structure and psychometric properties of three versions of the Everyday Discrimination Scale, with three different samples: the European Portuguese validation (EDS-PT, considering any reason for discrimination), using a sample of adults from the community (N = 610), a specific version for sexual minority (EDS-SM), with a sample of sexual minority individuals (N = 352), and a specific version for gender minority (EDS-GM), in a sample of gender minority individuals (N = 108). Factor structure and reliability of the different versions were examined. A second-order two-factor model (Everyday discrimination with factor 1 Unfair Treatment and factor 2 Personal Rejection) presented good adjustment and adequate reliability. Furthermore, all versions of EDS revealed weak to moderate correlations with indicators of convergent validity (mental health, satisfaction with life, social safeness, and social support). This study's outcomes provide insights into different types of everyday discrimination and suggest that the EDS-PT, EDS-SM and EDS-GM are valid and reliable measures useful in research and clinical contexts.
- ItemEfficacy and Cost-effectiveness of an ACT and Compassion-based Intervention for Women with Breast Cancer: study protocol of two randomised controlled trials {1}(Springer Nature | BMC Journals, 2025-01-03) Trindade, Inês A.; Soares, Andreia; Skvarc, David; Carreiras, Diogo; Pereira, Joana; Lourenço, Óscar; Sampaio, Filipa; Sousa, Bruno de; Martins, Teresa C.; Boaventura, Paula; Marta-Simões, Joana; Mind Project Team; Moreira, HelenaBackground: Breast cancer is the most diagnosed cancer in women worldwide and carries a considerable psychosocial burden. Interventions based on Acceptance and Commitment Therapy (ACT) and compassion-based approaches show promise in improving adjustment and quality of life in people with cancer. The Mind programme is an integrative ACT and compassion-based intervention tailored for women with breast cancer, which aims to prepare women for survivorship by promoting psychological flexibility and self-compassion. A pilot study of the Mind programme has shown acceptability and preliminary efficacy in improving quality of life and psychological health. This paper presents the study protocol of two randomised controlled trials that aim to test the efficacy and cost-effectiveness of an optimised version of the Mind programme in women with breast cancer. Methods: Participants will be women diagnosed with breast cancer randomly assigned to the Mind programme or a support group intervention (active control) in a 1:1 ratio for study 1, while study 2 includes one more arm (treatment as usual; inactive control) and a 2:2:1 ratio. Both interventions will be delivered weekly via an 8-session face-to-face or online group format. Data will be collected at baseline, post-treatment and 6-month follow-up. The efficacy and cost-effectiveness of the two interventions will be assessed. Treatment outcomes will comprise cancer-specific quality of life (primary outcome), anxiety and depressive symptoms, psychological flexibility, self-compassion, health-related quality of life, resource use, and intervention’s acceptability and feasibility. Study 1 will also include immunological and epigenetic markers associated with breast cancer prognosis and mental health. Outcome assessors will be blind to group allocation. Statistical analyses will be conducted using an intention-to-treat approach. Analyses of moderators and mediators of change will also be performed. Discussion: These trials examine the efficacy and cost-effectiveness of an integrative ACT and compassion-based intervention tailored for women with breast cancer. Greater improvements in psychosocial, biological and resource use are expected in the Mind group, when compared to the control group(s). Results will likely support the potential benefits of the Mind programme for breast cancer patients and highlight the clinical relevance of integrative and holistic interventions in oncology.
- ItemShame-Based Experiences of Homophobic Bullying and Mental Health: the mediating role of self-compassionate actions(MDPI, 2022-12-15) Seabra, Daniel; Gato, Jorge; Carreiras, Diogo; Petrocchi, Nicola; Salvador, Maria do CéuHomophobic experiences with traumatic characteristics related to shame are more frequent among sexual minority (SM) than heterosexual individuals. Concurrently, SM individuals present higher levels of psychopathology and transdiagnostic processes (e.g., shame) than heterosexual individuals. Self-compassion has been identified as a protective mechanism that counteracts the effects of shame. The current study aimed to analyse which components of self-compassion affect mental health and test the mediating role of self-compassion in the relationship between feelings of shame in traumatic homophobic bullying experiences (THBEs) and psychopathology indicators (depression, anxiety, and social anxiety symptoms). In this study, 190 Portuguese SM individuals (Mage = 28.3, SD = 7.5) completed self-report measures assessing traumatic experiences, self-compassion, and psychopathology. Data were explored with SPSS and AMOS. Regression analyses showed that internal shame felt during THBE and compassionate actions predicted psychopathology outcomes. Mediation analyses revealed that internal shame during a THBE had a significant indirect effect on all psychopathology outcomes through compassionate actions. In other words, internal shame during a THBEwassignificantlyassociated with depression, anxiety, and social anxiety, and these relationships were partially mediated by compassionate actions. Our results reinforce the importance of developing compassionate actions towards the self as a possible protective factor for psychopathology among SM individuals.
