Emotion regulation unveiled through the categorical lens of attachment.

BACKGROUND: Emotion regulation, the process by which individuals manage and modify their emotional experiences, expressions, and responses to adaptively navigate and cope with various situations, plays a crucial role in daily life. Our study investigates the variations in emotion regulation strategies among individuals with different attachment styles (AS). Specifically, we examine how individuals with secure, anxious, avoidant, and fearful attachment styles effectively utilize cognitive reappraisal and expressive suppression to regulate their emotions. METHODS: A total of n = 98 adults were instructed to attend, reappraise, or suppress their emotions while viewing negative and neutral images from the International Affective Picture System (IAPS) in an experimental emotion regulation task. After completing the task, participants rated the valence and arousal elicited by the images. Attachment styles were measured using the ECR-12 questionnaire and then categorized into four AS. RESULTS: Our study revealed that individuals with secure AS (n = 39) effectively reduced displeasure through cognitive reappraisal but experienced levels of displeasure with expressive suppression. Anxious AS (n = 16) individuals successfully reduced displeasure using cognitive reappraisal but struggled to regulate arousal and effectively use expressive suppression. Avoidant AS (n = 24) individuals could reduce displeasure with both strategies but experienced high arousal during suppression attempts. Fearful AS (n = 19) individuals effectively regulated both displeasure and arousal using either strategy. However, Secure AS individuals showed superior reappraisal efficacy, significantly reducing arousal levels compared to the Fearful AS group. Both Secure and Avoidant AS groups experienced higher valence during reappraisal relative to a baseline, indicating a decrease in displeasure. CONCLUSIONS: Individuals with different AS exhibit variations in the effectiveness of their use of emotion regulation strategies. Our findings reinforce the significance of AS in shaping emotion regulation processes and emphasize the need for tailored approaches to support individuals with different attachment orientations.

Relationship between inspiratory muscle strength and balance in women: A cross-sectional study.

BACKGROUND: There is scarce evidence on changes at the functional level associated with the respiratory area in women. This study aims to analyse the relationship between inspiratory muscle strength and balance in women. MATERIAL AND METHODS: In this cross-sectional observational study, the sample consisted of groups according to the results obtained in the balance test. Inspiratory muscle weakness was defined as maximum inspiratory pressure (MIP) ≤ 80% of the predictive value. MIP was carried out using through a mouthpiece, with an electronic manometer. Logistic regression model was used to examine if MIP predicts balance. RESULTS: 159 women participated in the study. Approximately 20% of them achieved balance ≤ 2 seconds and 18% presented MIP≤80%. MIP was associated with the time achieved in the one-leg support test. Subjects with MIP ≤ 80% of the predictive value show 3 times more risk of having a lower performance in the balance test (OR = 3.26). CONCLUSIONS: Inspiratory muscle weakness is associated with deficient balance in this sample. It shows the need for multidimensional assessment and rehabilitation strategies for patients identified as having MIP weakness and/or balance disorders.

Latin American Attachment studies: A narrative review.

Attachment theory´s core hypotheses (universality, normativity, sensitivity, and competence) are assumed to be applicable worldwide. However, the majority of studies on attachment theory have been conducted in Western countries, and the extent to which these core hypotheses are supported by research conducted in Latin America has never been systematically addressed. The purpose of this systematic narrative literature review is to provide an integrative discussion of the current body of empirical studies concerning attachment theory conducted in Latin American countries. For that purpose, a search was conducted in four electronic databases (Web of Science, PsycInfo, SciELO, and Redalyc) and 82 publications on attachment and/or sensitivity met inclusion criteria. None of the studies reported cases in which an attachment relationship was absent, and a predominance of secure attachment patterns was found, mainly for non-risk samples (NRS). Sensitivity levels were generally deemed adequate in NRS, and related to attachment quality. Attachment security and caregivers' sensitivity were positively associated with child outcomes. Attachment-based intervention studies mostly showed efficacy. In conclusion, Latin American research supports the key theoretical assumptions of attachment theory, mainly in samples of urban middle-class NRS. However, the field of attachment-related research would be enriched by also investing in Latin American studies on caregiving rooted in local concepts and theories.

Background: in the university stage many young people increase the consumption of ultra-processed food(UPF). The aim was to analyze the association between the consumption of UPF, overweight and abdominalobesity in young people who begin higher education.Methods: Analytical cross-sectional study. 139 young people participated who entered to the Faculty ofHealth Sciences of a university in Valparaíso, Chile. Food consumption was assessed using a QuantifiedConsumption Trend Survey; the NOVA system was used to classify 26 UPF into 8 subgroups. Body weight,height and waist circumference were measured to determine the Body Mass Index and the diagnosis ofabdominal obesity.Results: Young people with overweight more frequently consumed margarine, sauces and spreadable fats(p=0,007), sausages and other reconstituted meat products (p=0,049), and fast food (p=0,003); and thosewith abdominal obesity more frequently consumed pastry products, cookies and chocolates (p = 0,037),margarine, sauces and spreadable fats (p = 0,001) and fast food (p <0,000).Conclusions: Some UPF subgroups were associated with overweight and abdominal obesity. Decrease theconsumption of UPF could improve the nutritional status of young people. (AU)

Using Exploratory Structural Equation Modeling (ESEM) to Examine the Internal Structure of Posttraumatic Stress Disorder Symptoms.

Several studies have reported the factor structure of posttraumatic stress disorder (PTSD) using confirmatory factor analysis (CFA). The results show models with different number of factors, high correlations between factors, and symptoms that belong to different factors in different models without affecting the fit index. These elements could suppose the existence of considerable item cross-loading, the overlap of different factors or even the presence of a general factor that explains the items common source of variance. The aim is to provide new evidence regarding the factor structure of PTSD using CFA and exploratory structural equation modeling (ESEM). In a sample of 1,372 undergraduate students, we tested six different models using CFA and two models using ESEM and ESEM bifactor analysis. Trauma event and past-month PTSD symptoms were assessed with Life Events Checklist for DSM-5 (LEC-5) and PTSD Checklist for DSM-5 (PCL-5). All six tested CFA models showed good fit indexes (RMSEA = .051-.056, CFI = .969-.977, TLI = .965-.970), with high correlations between factors (M = .77, SD = .09 to M = .80, SD = .09). The ESEM models showed good fit indexes (RMSEA = .027-.036, CFI = .991-.996, TLI = .985-.992). These models confirmed the presence of cross-loadings on several items as well as loads on a general factor that explained 76.3% of the common variance. The results showed that most of the items do not meet the assumption of dimensional exclusivity, showing the need to expand the analysis strategies to study the symptomatic organization of PTSD.

Non-Random Distribution and Ecophysiological Differentiation of Pyropia Species (Bangiales, Rhodophyta) Through Environmental Gradients.

Recently 18 Bangiales seaweed species were reported for the Chilean coast, including Pyropia orbicularis and Pyropia variabilis (large [LM] and green [GM] morphotypes). Porphyra/Pyropia spp. occur mainly in the upper intertidal where desiccation stress is triggered by tidal fluctuations. However, the influence of environmental and ecophysiological variables and seasonal differences on Porphyra/Pyropia (microhabitats) intertidal distributions is unknown. Accordingly, we determined (i) the effect of environmental variables (temperature [T], relative humidity [RH], and photosynthetically active radiation [PAR]) and season on distribution, and (ii) physiological (cellular activity and lipid peroxidation [LPX]) and molecular responses (antioxidant enzymes expression at biochemical and transcript level) to desiccation stress in both Pyropia species and morphotypes (common garden experiment, on flat rocky platforms). Multivariate analyses of coverage and abundance in relation to environmental variables revealed a significant effect of temperature on P. variabilis GM distribution, GM dominating almost exclusively on rocky walls (where lowest PAR and T values but maximum RH were registered). Conversely, Pyropia orbicularis and Pyropia variabilis LM were found in high abundance on flat rocky platforms in summer, LM and GM also dominating flat rocky platforms in winter and spring. LPX and catalase activity did not differed among species in summer, while in winter activity and transcription of cat were higher in P. orbicularis than P. variabilis. Results suggest that tolerance to environmental stresses such as temperature could regulate the occurrence of P. variabilis GM on rocky walls; conversely, abundances of P. variabilis and P. orbicularis on flat rocky platforms would be also regulated by other abiotic and/or biotic factors.

Does the Type of Abuse Matter? Study on the Quality of Child Attachment Narratives in a Sample of Abused Children.

Child abuse has been associated with the development of insecure-disorganized patterns of attachment. However, the way in which different types of abuse relate to variations in attachment representations is not entirely clear. Thus, the objective of this study was to determine the relationship between three types of abuse (sexual abuse, physical abuse, and neglect) and the quality of child attachment representation, as assessed through attachment narratives. The results indicate that abuse in general, as well as each of its typologies in particular, is associated with insecure-disorganized attachment narratives. No differences were observed in the association between each individual type of abuse and the quality of attachment narratives, as well as between the number of abuse experiences and the quality of attachment. The findings are discussed from attachment theory and the literature on child development and maltreatment.
