Publicação Acesso Aberto Promover a literacia emocional em adultos: A raiva [material pedagógico/poster]2025-05-12 - Teixeira, Beatriz; Cerqueira, Eduarda; Pereira, Maria; Pais, Francisca; Soares, Beatriz; Xavier, Ana; Palmeira, Lara; Santos, SusanaPoster desenvolvido no âmbito da 3ª Edição da Semana da Sustentabilidade: O futuro é hoje.Publicação Acesso Aberto The Three-Factor Eating Questionnaire-R21: A confirmatory factor analysis in a Portuguese sample2020 - Duarte, Patrícia; Pinto-Gouveia, José; Palmeira, LaraThe Three-Factor Eating Questionnaire (TFEQ) is one of the most widely used instruments to study different eating behaviors. It measures three types of eating behaviors namely: cognitive restraint, uncontrolled eating and emotional eating. The present study aims to evaluate the factor structure and reliability of the Portuguese version of the TFEQ-R21, using a confirmatory factor analysis (CFA). The sample includes 468 participants from the general population, with ages ranging from 18 to 60 years. Results from the CFA confirmed the TFEQ-R21 three-factor structure and the model revealed an acceptable fit to the data (χ2(186) = 443.211, p < 0.001; χ2/df = 2.329; CFI = 0.933; TLI = 0.925; RMSEA = 0.054; SMRS = 0.053). Multigroup analysis results support strong measurement invariance across genders. Furthermore, all three dimensions presented adequate psychometric properties. Overall, results support that the Portuguese version of the TFEQ-R21 is a useful, reliable and robust instrument to assess relevant eating behaviors.Publicação Acesso Aberto Southampton mindfulness questionnaire: Confirmatory factor analysis and psychometric properties across portuguese clinical and non‐clinical samples2021-08-15 - Martins, Maria João; Marques, Cristiana C.; Guiomar, Raquel; Castilho, Paula; Xavier, Ana; Palmeira, LaraObjectives Southampton Mindfulness Questionnaire (SMQ) is one of the available instruments to assess mindfulness and has been described as particularly suited for clinical populations. The original study of the SMQ conceptualized it as having four facets, but yielded a single factor structure. The aim of this study was to confirm the SMQ factor structure and examine its psychometric properties in clinical and non-clinical Portuguese samples. Methods The community sample comprised 243 participants, ranging from 18 to 77 years. Additionally, to assess sensitivity, two distinct samples were used: individuals with meditation experience (n = 30) and a clinical sample (43 individuals with psychosis). Factor structure, reliability, validity, and sensitivity analyses were performed. Results Confirmatory factor analyses of the SMQ seem to support one overarching mindfulness construct containing four facets, revealing an acceptable fit through a parceling method. Significant correlations were obtained between SMQ and another mindfulness measure, and also with measures of cognitive fusion, and positive and negative affect. Results also indicated significant differences in SMQ non-judging facet between meditators and non-meditators and clinical samples. Conclusions The results indicate that although the SMQ has shown adequate reliability and validity, some limitations to the measure have been found. Further studies are needed, particularly with clinical samples, to determine how the current SMQ version could be improved and whether it should be revised.Publicação Acesso Restrito Positive emotional memories, stigma, and mental health in sexual and gender minority adults: The mediating role of self-compassion and social support2025-06-23 - Palmeira, Lara; Silva, Joana; Veloso, Bruna; Xavier, AnaLiterature reveals that memories of warmth and safeness, self-compassion, and social support are positively related to mental health. The present study aimed to analyze the impact of early memories of warmth and safeness and internalized homophobic stigma on mental health, through self-compassion and perceived social support, in sexual and gender minority adults. With a cross-sectional design, this study included a sample of 203 sexual and gender minority individuals (Meanage = 27.74; Standard Deviationage = 8.75). Data collection occurred online between March and June 2022. Self-report ques- tionnaires were administered to assess the constructs under study. Positive correlations were found between early positive memories, self-compassion, perceived social support, and mental health. On the contrary, internalized stigma showed significant and negative correlations with self-compassion, perceived social support, and mental health. In addition, results confirmed the indirect effects of memories of warmth and safeness on mental health through self-compassion and social support. Also, the impact of stigma on mental health occurred entirely through self-compassion and social support. These results suggest the importance of promoting self-compassion and social support to address internalized stigma and thus improve sexual and gender minority adult’s mental health.Publicação Acesso Aberto The longitudinal impact of psychological flexibility and compassion on mother-baby bonding: Care4mmmies study protocol [comunicação oral]2023-03-30 - Mateus, Vera; Palmeira, Lara; Xavier, Ana; Silva, Joana Ribeiro da; Vagos, PaulaBecoming a mother is a life-changing event that is often experienced in a positive way, but may also encompass great vulnerability and uncertainty, with the potential to hinder the mother’s well-being and foster disorganization, particularly for women with attachment difficulties dealing with a difficult infant. Risk factors to the quality of mother-infant emotional bonding are well documented, whereas research into the mothers’ protective and modifiable factors is scarcer. Psychological flexibility and compassion are adaptive emotional regulation strategies that have been linked to the wellbeing and mental health in diverse populations. The current work intends to present the Care4mommies project, which aims to examine whether prenatal maternal compassion (towards others and the self) and psychological flexibility play a protective role in the development of postpartum mother-infant bonding over time and whether this effect remains relevant regardless of mothers’ attachment style and infant temperament. Participants will be pregnant women to be assessed between 22 and 30 weeks of gestation (T0) and when the infant is three (T1) and nine months old (T2). Participants will respond to an online survey that includes sociodemographic information and questionnaires about their compassion and psychological flexibility to be completed at all three assessments. In addition, mothers’ own attachment style will be reported during pregnancy, and infant temperament and mother-infant bonding questionnaires will be administered at T1 and T2. Recruitment will take place through social media advertising, colleagues and acquaintances of the research team members, and family health units attending pregnant women. Data will be analysed using a structural equation modelling approach. Overall, we expect that higher levels of mother’s compassion and psychological flexibility will predict higher quality of mother-infant bonding. In addition, we expect that the impact of less adaptive maternal attachment styles and infant difficult temperament on mother-infant bonding will be moderated by mother’s compassion and/or psychological flexibility. Finally, we expect mother-infant bonding at T2 to be predicted by mothers’ attachment style, compassion and psychological flexibility, infant temperament, and mother-infant bonding previously assessed. The study findings will clarify whether mothers’ compassion and psychological flexibility may be protective for mother-infant bonding, which can inform future studies in designing and testing specific parental interventions to promote a secure mother-infant bond in the postpartum period.Publicação Acesso Restrito Online compassion focused therapy for overeating (CFT-OE): Feasibility and acceptability pilot study2023-12-21 - Marques, Cristiana; Castilho, Paula; Rodrigues, Dírcea; Mayr, Andreas; Soares Pina, Tiago; Pereira, Ana Telma; Castelo-Branco, Miguel; Goss, Kenneth; Palmeira, LaraObjective: This pilot study aims to investigate the feasibility, acceptability and potential effectiveness of online Compassion Focused Therapy for overeating (CFT-OE). Method: Eighteen Portuguese women seeking treatment for overeating enrolled in this study, and 15 participants completed the CFT-OE. This was a single-arm study. Participants were assessed at pre- and post-intervention and 3-month follow-up. All participants completed measures assessing binge eating, cognitive restraint, uncontrolled eating, emotional eating, general eating psychopathology, general and body shame, self-criticism, self-compassion and fears of self-compassion. Results: The treatment attrition rate was 16.7%, which is relatively low compared to other similar online interventions. Participants gave positive feedback on the program and indicated they would recommend it to people with similar difficulties. CFT-OE improved self-compassion and reduced eating psychopathology symptoms, general and body shame, self-criticism and fears of self-compassion. Clinical significance analysis showed that the majority of participants were classified as in recovery in all measures at post-intervention and 3-month follow-up. Discussion: Preliminary results suggest that the online CFT-OE program is an acceptable and feasible intervention. Results also suggest that CFT-OE is beneficial for the treatment of women with difficulties with overeating. A future randomized controlled trial is necessary to establish the effectiveness of the CFT-OE.Publicação Acesso Aberto eBEfree: Combining Psychoeducation, Mindfulness, and Self-Compassion in an App-Based Psychological Intervention to Manage Binge-Eating Symptoms: A Randomized Controlled Trial2025-03-29 - Senra, Hugo; Duarte, Cristiana; Carvalho, Sérgio A.; Simões, Luís; Ferreira, Cláudia; Palmeira, Lara; Matos, Marcela; Cunha, Marina; Castilho, Paula; Sousa, Bruno; Cordeiro, Luis; Pinto-Gouveia, JoséTo develop and test the effectiveness of the eBEfree program, a 12-session app-based version of a previously tested psychological intervention (BEfree) that combines psycho-education, self-compassion, mindfulness, and Acceptance and Commitment Therapy to reduce binge-eating symptoms. Two-hundred participants with recurrent elevated binge-eating symptoms and a higher body weight were enrolled in a remote parallel-group randomized trial, of which 142 completed the initial assessment (70 in the intervention group). The end-of-treatment and follow-up assessments were conducted 12 weeks after the initial assessment and 26 weeks after the end of treatment, respectively. Intention-to-treat (ITT) analyzes were undertaken using frequentist linear mixed models and Bayesian hierarchical models to test the intervention effectiveness. 43 (waitlist control) and 29 (intervention) participants completed the end-of-treatment assessment, showing a high attrition rate (51%). ITT analyzes showed the eBEfree program to be associated with a significant reduction in binge eating symptomatology from baseline to end-of-treatment (β = −9.49, ρ < 0.0001, g = −1.17), and from end-of-treatment to 26-weeks follow-up (β = −6.01, ρ = 0.04, g = −1.08). At end-of-treatment, the intervention was also associated with a decrease in body mass index and depression symptomatology, as well as an improvement in dimensions of self-criticism and mindfulness. More than 80% of participants rated the quality of the program as positive and helpful. This trial suggests potential benefits of the eBEfree program to help individuals manage symptoms of binge-eating more effectively, reduce weight, and improve well-being and mental health. The intervention benefits should be confirmed in future larger trials. Treating binge-eating (BE) symptoms and associated comorbidities might be challenging for mental health services. Digital and app-based interventions can be a valuable resource to help people manage symptoms and improve well-being and mental health. The current trial suggests the potential benefits of an app-based intervention (eBEfree program) to help people reduce BE symptoms and develop psychological strategies to promote well-being and mental health.Publicação Acesso Aberto A Theory- and Evidence-Based Digital Intervention Tool for Weight Loss Maintenance (NoHoW Toolkit): Systematic Development and Refinement Study2021-12-03 - Marques, Marta M.; Matos, Marcela; Mattila, Elina; Encantado, Jorge; Duarte, Cristiana; Teixeira, Pedro J.; Stubbs, R. James; Sniehotta, Falko F.; Ermes, Miikka; Harjumaa, Marja; Leppänen, Juha; Välkkynen, Pasi; Silva, Marlene N.; Ferreira, Cláudia; Carvalho, Sérgio; Horgan, Graham; Heitmann, Berit Lilienthal; Evans, Elizabeth H.; Palmeira, António L.; Palmeira, LaraMany weight loss programs show short-term effectiveness, but subsequent weight loss maintenance is difficult to achieve. Digital technologies offer a promising means of delivering behavior change approaches at low costs and on a wide scale. The Navigating to a Healthy Weight (NoHoW) project, which was funded by the European Union’s Horizon 2020 research and innovation program, aimed to develop, test, and evaluate a digital toolkit designed to promote successful long-term weight management. The toolkit was tested in an 18-month, large-scale, international, 2×2 factorial (motivation and self-regulation vs emotion regulation) randomized controlled trial that was conducted on adults with overweight or obesity who lost ≥5% of their body weight in the preceding 12 months before enrollment into the intervention. [...]Publicação Acesso Aberto An individual participant data meta-analysis investigating the mediating role of eating behavior traits in Acceptance and Commitment Therapy-based weight management interventions2025-06-02 - Kudlek, Laura; Mueller, Julia; Colombo, Patricia Eustachio; Stephen J. Sharp; Boothby, Clare E.; Griffin, Simon J.; Butryn, Meghan; Chwyl, Christina; Forman, Evan; Hagerman, Charlotte; Hawkins, Misty; Juarascio, Adrienne; Knäuper, Bärbel; Kolehmainen, Marjukka; Levin, Michael E.; Lillis, Jason; Maiz, Edurne; Manasse, Stephanie; Palmeira, Lara; Pietiläinen, Kirsi H.; Sherwood, Nancy E.; Ahern, AmyIdentifying mechanisms of action can aid the refinement of weight management interventions. Acceptance and Commitment Therapy (ACT)-based interventions may support long-term weight management by improving self-regulation of eating behavior traits (EBTs). However, it remains unclear if changing EBTs like emotional eating, external eating, internal disinhibition, and restraint during ACT causes improved weight management.Publicação Acesso Aberto Next-generation sequencing of 12 obesity genes in a Portuguese cohort of patients with overweight and obesity2023-04 - Manco, Licínio; Pereira, Janet; Fidalgo, Teresa; Cunha, Marina; Pinto-Gouveia, José; Padez, Cristina; Palmeira, LaraWe examined 12 monogenic obesity genes in 72 Portuguese individuals with overweight and obesity (class 1 and class 2), some of which with suspected genetic obesity, to identify known or unknown potential obesity variants. Genomic DNA was analyzed for variants in genes LEP, LEPR, MC4R, POMC, PCSK1, BDNF, NTRK2, SIM1, SH2B1, UCP3, GCG and ADCY3 through next generation sequencing (NGS). The impact of the rare variants was investigated in the ClinVar database and using in silico tools for prediction of pathogenicity. Four potential pathogenic missense variants were detected at the heterozygous state in five individuals: two in the ADCY3 gene, NM_004036.5:c.1153G > A (p.Val385Ile) (rs756783003) and NM_004036.5:c.1222G > A (p.Gly408Arg) (rs201606553), one in gene SH2B1, NM_001145795.1:c.127C > A (p.Arg43Ser) (rs547678855), and the fourth in gene POMC NM_000939.4:c.706C > G (p.Arg236Gly) (rs28932472), which was found in two individuals. Moreover, six rare variants near splicing sites were also identified, as well as eight rare synonymous variants. In summary, some potential pathogenic rare missense variants were identified, two of them in ADCY3 gene, the most recently identified gene as having a role in monogenic obesity. Further analysis should be performed to confirm the clinical relevance of these variants.
