Suicidal behavior is a complex and multifactorial phenomenon whose characterization, assessment, prevention, intervention, and postvention require a comprehensive approach focused on the meaning in a person's life and their suffering in their biographical, social and cultural context. It is an extraordinarily variable phenomenon over time and highly dependent on contextual elements.Method: This editorial includes the social determinants of this phenomenon, key aspects linked to the dehumanization of healthcare settings, the problems of iatrogenic harm in universal prevention programs for schoolchildren and adolescents, and good clinical practices collected in the scientific literature.Results: The editorial highlights the importance of research for the prevention of suicidal behavior from any intervention level, whether educational, community, social, or health, as all are involved in prevention.Conclusions: The goal is to help improve the biographical circumstances of people with suicidal behaviors and the meaningfulness of their lives. This must be done through a collective scaffolding in which the most vulnerable can ask for help when they need it, as well as guide themselves towards life circumstances worth living.","PeriodicalId":48179,"journal":{"name":"Psicothema","volume":null,"pages":null},"PeriodicalIF":3.2,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142510553","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The scores explained the dimensions of sexual functioning, especially sexual arousal and erection/lubrication.

One widely-used mentalization questionnaire is the Mentalization Questionnaire (MZQ; Hausberg et al., 2012), which we aimed to adapt and validate for use in Spanish.Method: We adapted the MZQ to European Spanish and evaluated its psychometric properties in both adolescent (n = 389, ages 12-19, M = 14.5) and adult community samples (n = 382, M = 48).Results: Confirmatory factor analysis resulted in a unidimensional structure including all items. This model had better goodness of fit than the original and other adaptations. Invariance analysis showed the same structure in adolescents compared by sex and age, and additionally in the adult versus adolescent samples. Evidence for convergent and discriminant validity was found. Internal consistency values in both adolescents and parents were fair and in the adolescent sample the MZQ scores remained moderately stable after re-test.Conclusions: The Spanish adaptation of the MZQ presents similar evidence of reliability and validity in the adolescent and adult samples.

The microbiota and gut-brain axis have been proposed as playing a mediating role in the regulation of stress and emotion.Method: Young male rats were exposed to maternal separation (MS) together with maternal and postnatal consumption of a HFS diet (45%kcal saturated fat, 17%kcal sucrose). Anxiety-like behaviour was evaluated using an elevated zero-maze, and depression-like behaviour using the forced-swim and sucrose preference tests. Microbiota composition and derived metabolites were also analysed in faecal samples using a gas chromatograph and mass spectrometry.Results: Combined exposure to MS and lifelong consumption of a HFS diet partially reversed the abnormal anxiety-like and depression-like behaviours in early adulthood caused by each adverse factor alone. Diet composition had a greater negative impact than ELS exposure on the gut microbiota, and both environmental factors interacted with microbiota composition partially counteracting their negative effects.Conclusions: The effects of exposure to early life stress and a HFS diet independently are partially reversed after the combination of both factors. These results suggest that ELS and diet interact to modulate adult stress response and gut microbiota.","PeriodicalId":48179,"journal":{"name":"Psicothema","volume":null,"pages":null},"PeriodicalIF":3.6,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140853269","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Furthermore, most of the findings about the nomological network were in line with prior hypotheses: All four SD4 scales were associated with low levels of agreeableness and antagonism; psychopathy was also related to low conscientiousness, disinhibition and impulse-control problems; narcissism was positively associated with extraversion and negatively associated with internalizing symptoms; Machiavellianism was uncorrelated with impulsivity-related problems, which made it distinct from the psychopathy profile; finally, sadism showed a similar pattern of associations to psychopathy, albeit less strongly linked to impulsivity problems and externalizing behavior.Conclusions: Overall, the SD4 presents sound psychometric properties, although the overlap between psychopathy and sadism warrants some caution.","PeriodicalId":48179,"journal":{"name":"Psicothema","volume":null,"pages":null},"PeriodicalIF":3.6,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140866769","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We assessed pre-adoption and post-adoption factors and evaluated cross-informant discrepancies.Results: Internationally adopted adolescents exhibited more internalizing problems by parent-report than community adolescents, but there were no differences by self-report. Adopted youth showed no discrepancies between parent and self-report, whereas community adolescents reported more internalizing symptoms than their parents. Pre-adoption adversity-related factors predicted parent-reported internalizing problems, while post-adoption factors predicted self-reported internalizing problems.Conclusions: Parent-adolescent informant discrepancies in adopted adolescents from Eastern Europe for internalizing symptoms were lower than in community adolescents.

Subject matter experts (SMEs) are commonly employed to evaluate the relevance, representativeness, and appropriateness of the items. This article proposes incorporating item response theory (IRT) into model assessments conducted by SMEs. Using IRT allows for the estimation of discrimination and threshold parameters for each SME, providing evidence of their performance in differentiating relevant from irrelevant items, thus facilitating the detection of suboptimal SME performance while improving item relevance scores.Method: Use of IRT was compared to traditional validity indices (content validity index and Aiken's V) in the evaluation of items. The aim was to assess the SMEs' accuracy in identifying whether items were designed to measure conscientiousness or not, and predicting their factor loadings.Results: The IRT-based scores effectively identified conscientiousness items (R2 = 0.57) and accurately predicted their factor loadings (R2 = 0.45). These scores demonstrated incremental validity, explaining 11% more variance than Aiken's V and up to 17% more than the content validity index.Conclusions: Modeling SME assessments with IRT improves item alignment and provides better predictions of factor loadings, enabling improvement of the content validity of measurement instruments.","PeriodicalId":48179,"journal":{"name":"Psicothema","volume":null,"pages":null},"PeriodicalIF":3.6,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140872155","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
