RESUMEN

BACKGROUND: Mindful eating is a concept that is increasingly being used to promote healthy eating. Observational studies have suggested associations with healthier eating behaviors, lower weight status, and favorable cardiovascular biomarkers. However, existing scales assessing mindful eating have some limitations. Our study aimed to develop and validate a scale assessing the level of mindful eating in a general population. METHODS: The Mind-Eat Scale was developed in four main steps: 1. Generating an initial item pool covering all aspects of mindful eating; 2. Reviewing items with experts and naive individuals; 3. Administering the scale to a large and representative sample from the NutriNet-Santé cohort (N = 3102); 4. Conducting psychometric analyses. Construct validity was assessed using exploratory (EFA) (N1 = 1302) and confirmatory (CFA) (N2 = 1302, N3 = 498) factor analyses. Content, discriminant, convergent, and divergent validity, internal consistency, and test-retest reliability were examined. RESULTS: The initial pool of 95 items was refined to 24 items using EFA. The EFA highlighted six dimensions: Awareness, Non-reactivity, Openness, Gratitude, Non-judgement, and Hunger/Satiety, consisting of four items per dimension. CFAs showed a good fit for first and second-order models. Adequate content validity was confirmed. Discriminant, convergent, and divergent validity were supported by significant differences between subgroups of individuals, and correlations with eating behaviors and psychological well-being scales. The Mind-Eat Scale showed good reliability for all six dimensions, with high McDonald's ω and adequate intraclass correlation coefficients (ICC). CONCLUSIONS: This study validated the first tool assessing a total mindful eating score and its sub-dimensions in a general population. This scale can be an asset for clinical and epidemiological research on dietary behavior and related chronic diseases.

RESUMEN

The Attentional Control Theory (ACT) posits that, while trait anxiety may not directly impact performance, it can influence processing efficiency by prompting the use of compensatory mechanisms. The specific nature of these mechanisms, which might be reflective, is not detailed by the ACT. In a study involving 110 students (M = 20.12; SD = 2.10), surveys were administered to assess the students' metacognitive beliefs, trait anxiety, and emotion regulation strategies (ERSs). The participants engaged in two working memory exercises: the digit span task from the WAIS-IV and an emotional n-back task. The findings indicated that anxiety, metacognitive beliefs, and maladaptive ERSs did not affect task performance but were correlated with increased response times. Several regression analyses demonstrated that a lack of confidence in one's cognitive abilities and maladaptive ERSs predict higher reaction times (RT) in the n-back task. Additionally, maladaptive ERSs also predict an increased use of strategies in the digit span task. Finally, two mediation analyses revealed that anxiety increases processing efficiency, and this relation is mediated by the use of maladaptive ERSs. These results underscore the importance of the reflective level in mediating the effects of trait anxiety on efficiency. They highlight the necessity of incorporating metacognitive beliefs and maladaptive emotion regulation strategies for a thorough comprehension of the Attentional Control Theory. Recognizing these factors offers valuable perspectives for enhancing cognitive capabilities and fostering academic achievement.

RESUMEN

BACKGROUND: Some studies have reported associations between self-esteem and weight status, but longitudinal data on adults remain scarce. The aim of this population-based study was to analyze the cross-sectional and longitudinal association between self-esteem and body mass index (BMI) and to investigate whether baseline BMI has an impact on this association. METHODS: In 2016, 29,735 participants aged ≥ 18 years in the NutriNet-Santé cohort completed the Rosenberg Self-Esteem Scale. BMI was self-reported yearly over a 4-year period. Association between self-esteem and BMI was assessed using mixed models and logistic regressions. Analyses were stratified by BMI (categorical) at baseline and adjusted on sociodemographic and lifestyle characteristics. RESULTS: At baseline, higher self-esteem was associated with higher BMI in normal weight individuals(p = 0.32), and with lower BMI in obese class II and III individuals (p = 0.13). In addition, higher baseline self-esteem was associated with BMI increase over time in normal weight individuals (p = 0.15). Among normal weight individuals, those with higher self-esteem were less likely to show a decrease in their BMI (p = 0.005), while no association was observed with BMI increase (p = 0.81). DISCUSSION: Our findings suggest that the association between self-esteem and BMI depends on the initial category of BMI, with a negligible effect of self-esteem.

RESUMEN

BACKGROUND: A significant number of individuals with alcohol use disorder remain unresponsive to currently available treatments, which calls for the development of new alternatives. In parallel, psilocybin-assisted therapy for alcohol use disorder has recently yielded promising preliminary results. Building on extant findings, the proposed study is set to evaluate the feasibility and preliminary clinical efficacy of psilocybin-assisted therapy when incorporated as an auxiliary intervention during inpatient rehabilitation for severe alcohol use disorder. Moreover, it intends to pinpoint the modifications in the two core neurocognitive systems underscored by dual-process models of addiction. METHODS: In this double-blind, randomized, placebo-controlled, 7-month parallel-group phase II superiority trial, 62 participants aged 21-64 years will be enrolled to undergo psilocybin-assisted therapy as part of a 4-week inpatient rehabilitation for severe alcohol use disorder. The experimental group will receive a high dose of psilocybin (30 mg), whereas the control group will receive an active placebo dose of psilocybin (5 mg), both within the context of a brief standardized psychotherapeutic intervention drawing from key elements of acceptance and commitment therapy. The primary clinical outcome is the between-group difference regarding the change in percentage of heavy drinking days from baseline to four weeks posthospital discharge, while safety and feasibility metrics will also be reported as primary outcomes. Key secondary assessments include between-group differences in terms of changes in (1) drinking behavior parameters up to six months posthospital discharge, (2) symptoms of depression, anxiety, trauma, and global functioning, (3) neuroplasticity and key neurocognitive mechanisms associated with addiction, and (4) psychological processes and alcohol-related parameters. DISCUSSION: The discussion outlines issues that might arise from our design. TRIAL REGISTRATION: EudraCT 2022-002369-14 and NCT06160232.

RESUMEN

Trait anxiety, emotion regulation strategies, and metacognitive beliefs influence executive functions (EFs) and academic achievement. This study examines their interplay and impact on academic success. In total, 275 adolescents (10-17 years) and parents completed an online questionnaire assessing trait anxiety, emotion regulation strategies, metacognition, parent-reported behaviors related to executive functioning, and overall school average. Preliminary analyses confirmed consistency with the existing literature for each variable and their interaction. Furthermore, we conducted a network analysis among the main variables. This analysis supports the need to pay more attention to reflective variables-maladaptive emotion regulation strategies and metacognitive beliefs about worry-when studying trait anxiety. These variables were linked to problematic executive functioning in adolescents, and the latter was negatively linked to academic achievement. This study offers innovative insights by investigating relationships less explored in the scientific literature. It reveals high and significant correlations between metacognitive beliefs, maladaptive emotion regulation strategies, and trait anxiety (r > 0.500, p < 0.001) but also between these variables and both executive functioning and academic achievement. These findings offer new perspectives for research and underscore the importance of holistically examining the psychological factors related to academic success.

RESUMEN

Context: Parental burnout increases the risk of deleterious consequences on parents’, couples’, and children's physical and mental health. Methods: The current study (N = 134) aimed to assess the effectiveness of a Cognitive Behavioural Stress Management (CBSM) group programme in terms of parental burnout reduction. In total 67 parents attended the 8-week CBSM intervention groups, and another 67 parents were assigned to the waiting-list control group. We compared the effectiveness of the CBSM intervention with a waiting-list control group directly after the end of the programme and at three-months follow-up. Results: The results showed that compared to the control group the CBSM programme contributed to the reduction of parental burnout symptoms with statistically significant and small effect size. Moreover, the contrast analyses showed that the reduction in parental burnout severity was maintained at 3 month-follow-up. The reduction in parental burnout scores was mediated by the decrease in stress and the increase in unconditional self-kindness. Conclusions: These results highlight the potential benefits of the CBSM programme for parental burnout prevention and reduction. (AU)

RESUMEN

Both creativity and responsibility are important higher-order skills to develop to meet the challenges of the Anthropocene, and both are related to attentional states of consciousness and to ethics. Meditation is a set of practices that trains attentional and emotional regulation. A few studies have shown that different kinds of meditation can foster different kinds of creative thinking, and others have begun to investigate the effect of the combination of meditation and ethics on ethical characteristics (but not yet on creativity or precisely on responsibility, so far). Here, we present a nonrandomized trial with an active control group among second-year science university students (n = 84) to test the effect of the secular Meditation-Based Ethics of Responsibility (MBER) program on creative potential, self-reported awareness, and sense of one's own responsibility. The results show a large effect of the program on sense of one's own responsibility and convergent and divergent creative writing tasks, both in conceptual-semantic and engineering-like verbal ideation. They also suggest that convergent conceptual-semantic thinking might moderate the effect of the MBER program on the awareness and sense of one's own responsibility. This work opens up new research and educational perspectives linked to necessary behavioral changes in the Anthropocene.

RESUMEN

Cold plasmas have found their application in a wide range of biomedical fields by virtue of their high chemical reactivity. In the past decades, many attempts have been made to use cold plasmas in wound healing, and within this field, many studies have focused on plasma-induced cell proliferation mechanisms. In this work, one step further has been taken to demonstrate the advanced role of plasma in wound healing. To this end, the simultaneous ability of plasma to induce cell proliferation and permeabilize treated cells has been examined in the current study. The driving force was to advance the wound healing effect of plasma with drug delivery. On this subject, we demonstrate in vitro the healing effect of Ar, Ar+N2 plasma, and their aerosol counterparts. A systematic study has been carried out to study the role of reactive oxygen species (ROS) and reactive nitrogen species (RNS) in cell adhesion, signaling, differentiation, and proliferation. An additional investigation was also performed to study the permeabilization of cells and the delivery of the modeled drug carrier fluorescein isothiocyanate (FITC) labeled dextran into cells upon plasma treatment. Short 35 s plasma treatments were found to promote fibroblast adhesion, migration, signaling, proliferation, and differentiation by means of reactive oxygen and nitrogen species (RONS) created by plasma and deposited into the cell environment. The impact of the plasma downstream products NO2- and NO3- on the expressions of the focal adhesion's genes, syndecans, and collagens was observed to be prominent. On the other hand, the differentiation of fibroblasts to myofibroblasts was mainly initiated by ROS produced by the plasma. In addition, the ability of plasma to locally permeabilize fibroblast cells was demonstrated. During proliferative cell treatment, plasma can simultaneously induce cell membrane permeabilization (d ∼ 7.3 nm) by the species OH and H2O2. The choice for a plasma or a plasma-aerosol configuration thus allows the possibility to change the spatial chemistry of drug delivery molecules and thus to locally deliver drugs. Accordingly, this study offers a pivotal step toward plasma-assisted wound healing advanced by drug delivery.

RESUMEN

Background: Understanding psychopathology in transitional age youth (TAY) requires a complex model, incorporating familial vulnerability and environmental factors. A trans-diagnostic and dimensional approach seems the most appropriate. Transition_psy study aims to assess factors playing a role in TAY psychopathology and to define predictors. Materials and methods: This article presents part of the Transition_psy study results, a case-control observational study. Youth aged 17 years old were recruited between June 2020 and December 2021, from both clinical [clinical population (CP) group] and non-clinical settings [non-clinical population (NCP) group]. Participants completed self-report questionnaires. The primary outcome to assess TAY psychopathology was the Youth-Self Report (YSR). We evaluated care needs with the Health of The Nation Outcome Scales For Children And Adolescents (HoNOSCA-SR) and quality of life with the World Health Organization Quality of Life - BREF (WHOQoL-BREF). Exposure factors included familial vulnerability, childhood, and present environmental factors, such as first-degree family history of psychopathology, the Childhood Trauma Questionnaire (CTQ) and the Family Assessment Device (FAD). YSR scores were compared, between groups, according to exposure factors with ANOVA and linear regression. We performed best subsets selection of multivariable analyses based on the Akaike Information Criterion. This study was registered with ClinicalTrials.gov (Identifier: NCT04333797). Results: A total of 220 TAY (CP = 106, NCP = 114) were included in the study. Participants were aged 17 years old. The majority were female (69.1%), single (96.8%), and born in Belgium (82.3%). Clinical data were all significantly different between CP and NCP groups. YSR scores were found statistically different according to group (p < 0.001), first-degree family history of psychopathology (p < 0.001), CTQ (p < 0.001), and FAD (p < 0.001). Predictive dimensional model suggested that TAY psychopathology can be predicted by group, CTQ and FAD. Significant positive correlation was found between YSR and HoNOSCA (rho = 0.81) and negative correlation between YSR and physical and psychological health (rho = -0.69 and -0.71, respectively). Conclusion: This study findings allowed to present a predictive dimensional model on TAY psychopathology, including belonging to a clinical population at transitional age, childhood trauma, and family dysfunction. Further research is needed to replicate Transition_psy study results in other samples. The proposed model could be used in clinical practice to improve assessment of TAY psychopathology.

RESUMEN

Self-compassion (SC) seems to play an important role in improving Emotion Regulation (ER). Nevertheless, the results of previous studies regarding the links between SC and ER are not consistent, especially facing diverse models of ER (strategy-based vs skill-based). The goal of this prospective study was to evaluate the links between these three concepts, by testing the predictive roles of SC and ER skills on both ER adaptive and maladaptive strategies, using standardised questionnaires and visual analogue scales. Results of regression analysis showed that self-compassion positively predicts cognitive reappraisal, acceptance, problem-solving, relaxation, self-support, tolerance and ER skills and negatively predicts behavioural avoidance, expressive suppression and ruminations. Results also showed that ER skills positively predict cognitive reappraisal, expression, acceptance, relaxation, self-support and tolerance and negatively predicts behavioural avoidance, expressive suppression and ruminations. Results from a mediation model are also promising regarding both the role of ER skills on the effect of SC on adaptive ER strategy use. Even if this study can be associated with common limits of self-report measures, it highlights the role of SC in a model of ER.

RESUMEN

Distinguishing between flexible and rigid cognitive restraint (CR) may be useful for understanding the role of CR in dietary behavior and weight status. This study aimed to translate and adapt the flexible and rigid CR scales to the French context and test their psychometric properties. Construct validity, internal consistency, and test-retest reliability were examined in a sample of 620 individuals. Confirmatory factor analysis of the scales found a two-factor structure (flexible CR: 12 items; rigid CR: 15 items) that provided a good fit and supported the initial solution (χ2 = 584.7, df = 322, CFI = 0.96, RMSEA = 0.052 [0.045, 0.059], TLI = 0.95). Higher flexible and rigid CR were associated with higher CR overall, emotional eating (TFEQ-R21) and eating disorders (SCOFF), and lower intuitive eating (IES-2). In addition, higher flexible CR was associated with lower impulsivity (BIS-11) while higher rigid CR was associated with higher uncontrolled eating (TFEQ-R21) and lower self-esteem (RSES), satisfaction with life (SWLS), and optimism (LOT-R). Flexible and rigid CR internal consistency was satisfactory (McDonald ω = 0.77 and 0.74, respectively) and test-retest reliability was good (ICC = 0.81 and 0.79, respectively). This study validated a flexible and rigid CR tool in a French population and confirmed that these two types of CR represent distinct eating behaviors.

RESUMEN

BACKGROUND: The promotion of multiple healthy lifestyles has been implemented as part of public health efforts to prevent and reduce the burden of non-communicable diseases. However, these interventions have shown a heterogeneity in their effectiveness. The pursuit of multiple daily goals may influence overall progress in achieving health goals. Horizontal inter-goal relations can be conflicting (due to time constraints) or facilitating (due to goal compatibility) and impact progress towards goal achievement. Personal values also play an important role in health promotion. Personal values direct attention towards accomplishing a higher-level goal through goal setting. Identifying the conflicting or facilitating relationships between health goals and personal values would provide insights in how individuals value health and the personal values that may support the adoption of a healthy behavior. The health goals that this study will focus on are physical activity and a healthy diet. METHODS: Participants between 18 and 30 years old residing in Belgium and interested in a healthy diet and/or physical activity, will be recruited. The study will be a mixed-methods research study based on an adapted personal project analysis for goal elicitation, goal appraisal, and rating of inter-goal conflicting or facilitating relations on a cross-impact matrix. The main objectives include examining the conflicting and facilitating relations between health goals and personal values. Secondary objectives include: examining correlations between horizontal and vertical goal relations; and the goal self-concordance score as a method of data triangulation of facilitating relations between goals and personal values. DISCUSSION: This study will provide insights into how the emerging adult population relate healthy behaviors, specifically physical activity and a healthy diet, to their personal values. The degree to which individuals are able to pursue a health goal is also influenced by other life goals, and therefore the conflicting and facilitating relations between health goals and other life goals will also be examined. This study contributes to multiple health behavior change theories and has implications for the formulation of interventions for the promotion of healthy behaviors.

RESUMEN

We agree that external validity of social psychological experiments is a concern, we disagree these models are useless. Experiments, reconsidered from a situated cognition perspective and non-linearly combined with other methods (qualitative and simulations) allow grasping decision dynamics beyond bias outcomes. Dynamic (vs. discrete) insights regarding these processes are key to understand missing forces and bias in real-world social groups.

RESUMEN

BACKGROUND: Resilience, the ability to bounce back or recover from stress, has been associated with several health-related behaviors. However, data on food intake and emotional eating are lacking. OBJECTIVES: The objective of this cross-sectional study was to analyze the associations between resilience and diet quality and ultraprocessed food (UPF) and food group consumption, and to assess whether emotional eating was a mediator of these associations. METHODS: In 2017, 17,840 participants (73.5% female, mean age = 55.4 ± 14.0 y) of the NutriNet-Santé study completed the Brief Resilience Scale, the revised 21-item Three-Factor Eating Questionnaire, and ≥3 self-administered 24-h dietary records. Diet quality was assessed with the modified French National Nutrition and Health Program Guideline Score. Foods and beverages consumed were categorized according to their degree of processing by the NOVA classification. We assessed the association between resilience and emotional eating using linear regression models. We also assessed the mediating role of emotional eating in the associations between resilience and diet quality, energy intake, and UPF and food group consumption, controlling for sociodemographic characteristics. RESULTS: In our study, resilience was negatively associated with emotional eating (P < 0.0001). More resilient participants had greater overall diet quality, greater intakes of seafood, whole-grain foods, fats, unsalted oleaginous fruits, and alcoholic beverages, and lower intakes of UPFs, starchy foods, dairy desserts, sugary fatty products, and sugar and confectionery (all P < 0.05). Emotional eating was a mediator of the inverse associations between resilience and intake of energy, UPFs, dairy desserts, sugary fatty products, and of the positive associations between resilience and alcoholic beverages (all P < 0.05), with a 20-70% mediation. CONCLUSIONS: Our findings showed that resilience was associated with an overall better diet quality in the NutriNet-Santé population-based study. These associations were partially explained by emotional eating. These findings suggest that resilience should be considered in the promotion of healthy dietary habits.The study is registered at clinicaltrials.gov as #NCT03335644.

RESUMEN

ABSTRACT: Anorexia nervosa (AN) is related to difficulties in emotion regulation, including a deficit in interoceptive awareness. The lack of interoceptive awareness is considered a vulnerability involved in the development and maintenance of anorexic symptoms. Surprisingly, no study has been conducted that focuses on these associations in an emotional context. This study measures the interoceptive awareness-using heartbeat self-counting and a sphygmomanometer-of 25 subjects suffering from AN and 25 control subjects, first at rest and then in an emotional situation. The results show that a deficit in interoceptive awareness was observed for the subjects suffering from AN at rest as well as when an emotional context was induced. This study encourages future investigations to focus on the impact of interoceptive deficit in AN to develop as efficient a care regimen as possible for these subjects.

RESUMEN

The possible benefits of an atmospheric pressure plasma jet skin treatment have been tested in vivo on mouse skin. Many studies have been conducted in vitro on mouse skin cells, but only a few in vivo where, due to the complexity of the biological system, plasma can cause severe damages. For this reason, we investigated how kHz plasma generated in a jet that is known to inflict skin damage interacts with mouse skin and explored how we can reduce the skin damage. First, the focus was on exploring plasma effects on skin damage formation with different plasma gases and jet inclinations. The results pointed to the perpendicular orientation of a He plasma jet as the most promising condition with the least skin damage. Then, the skin damage caused by a He plasma jet was explored, focusing on damage mitigation with different liquid interfaces applied to the treatment site, adding N2 to the gas mixture, or alternating the gas flow dynamics by elongating the jet's glass orifice with a funnel. All these mitigations proved highly efficient, but the utmost benefits for skin damage reduction were connected to skin temperature reduction, the reduction in reactive oxygen species (ROS), and the increase in reactive nitrogen species (RNS).

RESUMEN

Science education inclusive of learners' cultures requires understanding how students position scientific knowledge with regard to identity-laden beliefs, such as religions. To address this need, we developed a research tool administered across linguistic and societal contexts. In this article, we present the conceptual frameworks the instrument articulates and draws upon. We then test the construct validity and internal consistency of its dimensions based on data collected from a main sample of 238 English-speaking American, Dutch and Norwegian students, all in their final year of compulsory school education, as well as from a secondary sample of 372 French-speaking Belgian students that we use to further discuss the results from the main sample. The results obtained through exploratory and confirmatory factor analyses and by Cronbach's alpha analysis are consistent with our theoretical model. We discuss implications for the use of this instrument by researchers, as well as formal or informal science educators.

RESUMEN

Doctoral students face many challenges that were reinforced by COVID-19-related lockdowns. We assessed this impact over 1 year on doctoral students' depression, anxiety, stress, well-being, and doctoral engagement. We also investigated the potential protective role of self-compassion and savouring on mental health, well-being, and doctoral engagement. A total of 134 PhD students from several French universities responded to the three-time points of this longitudinal study. The results showed a significant increase in depression, anxiety and stress and a significant decrease in well-being and doctoral engagement during the first year of the pandemic. Self-compassion and savouring predicted lower levels of depression, anxiety, and stress, and higher levels of well-being over time. Savouring alone predicted higher doctoral engagement over time. This study reveals the significant impact of the pandemic year on the mental health of doctoral students, and the relevance of self-compassion and savouring as psychological resources to cope with adversity.

RESUMEN

Resilience is a positive psychological trait associated with a lower risk of some physical and mental chronic diseases and could be an important protective factor against eating disorders (EDs). The aim of this study was to assess cross-sectional and longitudinal associations between resilience and ED in a large cohort of French adults. In 2017, a total of 25,000 adults from the NutriNet-Santé cohort completed the Brief Resilience Scale (BRS). ED symptoms were measured in 2017 and 2020, with the Sick-Control-One-Fat-Food (SCOFF) questionnaire. Cross-sectional and longitudinal associations between resilience and EDs were analyzed using logistic regression, controlling for sociodemographic and lifestyle characteristics. Cross-sectional analyses showed that more resilient participants exhibited EDs less frequently than did less resilient participants (p < 0.0001). Longitudinal analyses showed that, during the three years of follow up, higher resilience was negatively associated with incident EDs (OR: 0.67, 95%CI: 0.61-0.74), persistent EDs (0.46 (0.42-0.51)), and intermittent EDs (0.66 (0.62-0.71)), compared with no ED. More resilient participants were also less likely to have a persistent ED than to recover from EDs (0.73 (0.65-0.82)). This study showed that resilience was associated with less ED symptoms and a higher chance of recovery.
