- The Portuguese version of the Difficulties in Emotion Regulation Scale and its relationship with psychopathological symptomsPublication . Coutinho, Joana; Ribeiro, Eugénia; Raquel Ferreirinha; Dias, PauloBackground: Emotion dysregulation is a unifier dimension of several psychopathological symptoms thus an instrument that measures it is needed. Objectives: To adapt to Portuguese the Difficulties in Emotion Regulation Scale and study its psychometric qualities. A second goal was to explore the association between DERS dimensions and specific types of psychopathology symptoms. Method: The original measure was translated to Portuguese and completed by a sample of 324 individuals who also completed the Brief Symptom Inventory. Results: The results show a very similar factor structure to the original measure: good testretest stability, very good internal consistency (Cronbach’s α = ,93) and good external validity with BSI. The analysis performed with the subset of 115 individuals that composed the clinical sample showed that psychopathologic individuals present more difficulties in emotion regulation than normal individuals. Through the correlation analysis between the different DERS and BSI subscales, we found that the Strategies and Goals subscales present the highest level of association with all the psychopathological symptoms. Discussion: This may suggest that these two dimensions are present in various psychological disorders and could, therefore, be included in psychological interventions focused on emotion regulation skills.
- Vagal modulation of 1-month-old infants to auditory stimuli is associated with self-regulatory behaviorPublication . Cruz, Sara; Ferreira-Santos, Fernando; Oliveira-Silva, Patrícia; Ribeiro, Eugénia; Gonçalves, Óscar; Sampaio, AdrianaDuring infancy, cardiac vagal modulation has been associated with attentional and social engagement behaviors. While studies have shown that infants display a behavioral repertoire that enables them to interact with others by being able to regulate themselves in order to attend to and to discriminate emotional and social cues, vagal modulation to sensory stimuli and its association with behavioral outcomes at early ages remains to be addressed. In this study, we analyzed the cardiac vagal response of 1-month-old infants to two auditory stimuli intensities and whether vagal response was associated with social interactive and self-regulatory abilities. Therefore, we recorded cardiac and respiratory physiological responses in 28 infants using a Biopac System. Neurobehavioral assessment was performed using the Neonatal Behavioral Assessment Scale. We observed increased respiratory sinus arrhythmia (RSA) amplitude to both auditory stimuli intensities when compared to baseline. No intensity effect was found for the RSA response. Additionally, we observed that higher RSA amplitude to both auditory stimuli was positively correlated with adjusted self-regulatory behaviors, suggesting a convergence between multiple measures assessing infants' state regulation. Results are discussed in light of 1-month-old infants' auditory stimuli processing and its implications for regulatory behaviors and the emergent social-like behaviors.
