The difficulties in emotion regulation scale: Dimensionality, measurement invariance, and physiological correlates in community adolescents.

OBJECTIVE: Emotion regulation is a central construct for the study of mental health in adolescence. Although the Difficulties in Emotion Regulation Scale (DERS) has been vastly used, several issues remain unanswered (e.g., factor structure/dimensionality). This study aimed to validate the 36-items DERS in a sample of 989 Portuguese community adolescent (460 boys; 529 girls; age ranged from 14 to 18). METHOD: A bifactor-ESEM model, comprising a general and six specific factors (nonacceptance; goals; impulses; strategies; clarity; awareness) was explored and considered the best fitting model. RESULTS: Gender measurement invariance was established. When compared with boys, although differences were small in magnitude, girls presented higher emotion regulation difficulties. Evidence for reliability and construct/temporal validity were found, and significant associations between the DERS and physiological measures of emotion regulation (i.e., Heart Rate and Heart Rate Variability) were established. CONCLUSION: Findings support the use of the DERS in adolescent samples.

Proposed Specifiers for Conduct Disorder (PSCD): Factor Structure and Validation of the Self-Report Version in Community and Forensic Samples of Portuguese Youth.

The Proposed Specifiers for Conduct Disorder (PSCD) was developed as a measure to assess the multifaceted model of psychopathic traits in children/youth (i.e., grandiose-manipulative [GM], callous-unemotional [CU], and daring-impulsive [DI] traits) in addition to Conduct Disorder (CD) symptoms. This study aims to test the psychometric properties of the PSCD-self-report version across community (n = 648; 52.9% female) and forensic male youth (n = 258) from the Portuguese population. Results supported a general factor and four specific factors (GM, CU, DI, CD), which was invariant across gender and sample type. Evidence for reliability, construct, and temporal validity were also found. Overall, the PSCD appears to be a promising measure for assessing psychopathic traits in youth from both community and forensic settings, which may contribute to the discussion around the conceptualization, assessment, predictive value, and clinical usefulness of the multifaceted model of psychopathy in youthful populations, particularly in its association with CD.

Dimensionality and measurement invariance of the Social Safeness and Pleasure Scale in adolescents from community and residential youth care.

BACKGROUND: Social safeness has been proposed as the individual's perception of the social world as being warmth and soothing. The lack of social safeness has been suggested as a transdiagnostic socio-emotional vulnerability for several mental health difficulties. To date there was no study addressing experiences of social safeness in adolescents. OBJECTIVE: To validate and study the psychometric properties of the Social Safeness and Pleasure Scale to Portuguese adolescents from community and residential care homes. PARTICIPANTS AND SETTING: A total of 731 Portuguese adolescents from community and residential youth care homes participated on this study. The community sample was composed of adolescents recruited from regular schools (208 boys; 224 girls). The residential youth care sample was composed of adolescents placed in residential care homes (145 boys; 154 girls). METHODS: A confirmatory factor analysis was conducted, and measurement invariance investigated. RESULTS: A one-factor solution presented a good fit across all samples and proved to be invariant (configural, metric, scalar and strict measurement invariance). Moreover, internal consistency values were excellent for all samples (α > 0.93) and evidence for construct validity in relation to external variables was found. Means comparisons revealed significant differences between all tested groups. Community adolescents reported higher social safeness in comparison to the adolescents placed in residential care. Within both samples, boys scored higher in the SSPS-A when compared to girls. CONCLUSIONS: These findings provide evidence on the SSPS-A validity and its use across diverse adolescent samples.

Measuring compassion toward others: Dimensionality of the compassion scale in community adolescents and in adolescents with behavioral disorders.

Compassion toward others has been defined as the sensitivity to the suffering of others with the genuine commitment to relieve/prevent it. The Compassion Scale (CS) measures this construct and despite its relevance during adolescence, studies have been mostly conducted with adults. This study investigated the psychometric properties of the Compassion Scale-Adolescents (CS-A) in community adolescents (n = 658; 409 girls) and in boys with behavioral disorders (n = 183), from 14 to 18 years old. Results showed the adequacy of a hierarchical-CFA measurement model, with a general score of compassion and four specific factors (i.e., Kindness, Common Humanity, Mindfulness and Indifference). Measurement invariance was tested across samples. Community girls presented higher levels of compassion when compared to boys. Also, behaviorally disturbed boys presented decreased levels of compassion when compared to community boys. Evidence for reliability and construct validity is also provided. The CS-A allows future research between genders in community adolescents. Additionally, future research exploring compassion using the CS-A, between community boys and samples of behaviorally disturbed boys, is now possible.

At the heart of change: Differences in young offenders' HRV patterns after the delivery of the PSYCHOPATHY.COMP program.

Introduction: Literature has pointed the need for intervention programs specifically tailored to target the treatment needs of young offenders, as well as the need to test the efficacy of such programs through physiological indexes of emotion regulation (e.g., heart rate variability; HRV), complementing self-reports typically used as outcome measures. The PSYCHOPATHY.COMP is a 20-session individual intervention program based on Compassion Focused Therapy aiming to reduce psychopathic traits and disruptive behavior among young offenders through the development of a compassionate motivation, while stimulating the soothing system as a strategy to improve emotion regulation. Previous research with young offenders has shown decreases in vagally mediated HRV (vmHRV) when the soothing system is activated. This physiological pattern seems to mirror threat-like responses that contrast with relaxed states. Methods: To test the efficacy of the PSYCHOPATHY.COMP, a clinical trial was implemented encompassing a treatment (n = 56) and a control group (n = 53). Treatment participants attended the PSYCHOPATHY.COMP, while controls received the Treatment As Usual (TAU) delivered in Portuguese juvenile detention facilities. HRV data was collected throughout a standardized procedure (encompassing resting, reactivity and recovery phases) specifically designed to trigger the soothing system. Participants were assessed at pre-treatment, post-treatment and 6-months follow-up. Results: Although treatment participants continued to process the soothing system as unpleasant (with decreased vmHRV), they seem to become able to adaptively recover from the stimuli without avoiding it or resorting to maladaptive coping strategies. The physiological pattern was in line with participants' decreases in difficulties in emotion regulation across the assessment periods. In contrast, controls seemed to have actively employed coping strategies associated with increases in vmHRV not only when the soothing system was triggered, but also when recovering from the stimuli. Congruently, for controls, increases in difficulties in emotion regulation were found, with increases in the lack of emotional clarity across the assessment periods. Discussion: Findings offer new evidence for the efficacy of the PSYCHOPATHY.COMP program in improving emotion regulation in young offenders, assessed through both self-report and physiological measures. Additionally, findings support the assessment of the autonomic balance as a treatment efficacy index in future research, targeting the rehabilitation of these youth.

HRV patterns associated with different affect regulation systems: Sex differences in adolescents.

Evolutionary perspectives of human behavior propose the existence of three emotion regulation systems (i.e., threat, drive and soothing systems). An unbalanced functioning of the systems represents greater risk for emotion dysregulation and psychopathology. In recent years, heart rate variability (HRV) has been reported as an accurate index of emotion regulation, and although adolescence is characterized by multiple neurophysiological, psychological and social changes, there is no study exploring the HRV patterns of each emotion regulation system in this developmental stage. In Study 1, a standardized procedure (SP) aiming to elicit the three different systems was developed and validated by experts (n = 14) and community adolescents (n = 31). In study 2, differences in HRV patterns across the three emotion regulation systems and across sex, were investigated in a sample of community adolescents (n = 155; 70 males), aged between 14 and 18 years old. Results showed that the threat and drive systems were associated with decreases in HRV, while the soothing system was associated with decreased heart rate. Sex differences were found for the activation of the threat system: while males maintained a decreasing trend in HRV indexes, from resting to recovery, females did not show a decrease in HRV during the activation of this system. Overall, physiological correlates of each specific emotion regulation system corroborate the theoretical assumptions. Moreover, a SP able to trigger each system independently while measuring physiological data is now available and can be used in future research.

Light-Activated Antimicrobial Surfaces Using Industrial Varnish Formulations to Mitigate the Incidence of Nosocomial Infections.

Evidence has shown that hospital surfaces are one of the major vehicles of nosocomial infections caused by drug-resistant pathogens. Smart surface coatings presenting multiple antimicrobial activity mechanisms have emerged as an advanced approach to safely prevent this type of infection. In this work, industrial waterborne polyurethane varnish formulations containing for the first time cationic polymeric biocides (SPBs) combined with photosensitizer curcumin were developed to afford contact-active and light-responsive antimicrobial surfaces. SPBs were prepared by atom transfer radical polymerization, which allows control over the polymer features that influence antimicrobial efficiency (e.g., molecular weight), while natural curcumin was employed to impart photodynamic activity to the surface. Antibacterial testing against Gram-negative Escherichia coli revealed that glass surfaces coated with the new formulations displayed photokilling effect under white-light (42 mW/cm2) irradiation within only 15 min of exposure. In addition, it was observed a combined antimicrobial effect between the two biocides (cationic SPB and curcumin), with a higher reduction in the number of viable bacteria observed for the surfaces containing cationic SPB/curcumin mixtures in comparison with the one obtained for surfaces only with polymer or without biocides. The waterborne industrial varnish formulations allowed the formation of homogeneous films without the need for addition of a coalescing agent, which can be potentially applied in diverse surface substrates to reduce bacterial transmission infections in healthcare environments.

Development and Validation of the Current Experiences of Warmth and Safeness Scale in Community and Residential Care Adolescents.

Interpersonal experiences of warmth and safeness have a key role on emotion regulation and social development during childhood and adolescence. This paper presents a new and brief scale designed to assess the adolescents' perception of current experiences of warmth and safeness (CEWSS-A). Its dimensionality and psychometric properties were investigated using a Portuguese sample of 453 adolescents from the community and 319 adolescents from residential care facilities. A confirmatory factor analysis indicated that the 12-item scale has a one-factor measurement model. The CEWSS-A showed adequate internal consistency in the different samples (α > .92) and construct validity in relation to external variables. The CEWSS-A proved to be group invariant. Community adolescents reported a higher frequency of current experiences of warmth and safeness in comparison with residential care participants, and boys showed significantly higher scores than girls, within both samples. The CEWSS-A is an appropriate self-report measure for clinical and research purposes.

Unique characterization of complex endocarditic vegetations using 3D TOE.

A 31-year-old male was admitted with suspected infective endocarditis, given a history of i.v. drug use, lung and cerebral abscesses and Staphylococcus aureus bacteraemia. TTE imaging was limited given supine positioning and mechanical ventilation but suggested a posterior mitral valve leaflet (PMVL) mass. Three-dimensional TOE provided uniquely detailed assessment of two complex infective masses. The attachment of the presumed P2 mass on TTE was indeterminant even on 2D-TOE, appearing attached to the PMVL or AMVL depending on rotational view (Fig. 1). 3D-TOE imaging and subsequent multiplanar and volume-rendered reconstruction revealed this to be a complex, large vegetation attached to the anterior aspect of the anterolateral commissure with mobile heads prolapsing into the left atrium and causing mild mitral regurgitation through a small basal perforation (Figs 2, 3 and Video 1). The second mass was a filamentous vegetation attached to the LVOT, prolapsing towards but not contacting the aortic valve (Fig. 4 and Video 2). Comprehensive assessment of complex vegetations is crucial for optimal surgical planning. 3D-TOE allows rapid, accurate, unique assessment of such masses through unlimited multiplanar reconstructions, volume-rendered real-time imaging and colour full-volume regurgitation assessment which may not always possible on 2D-TTE or 2D-TOE. 3D imaging should be routinely used in TOE and in particular in suspected endocarditis.
