Item type:Publication, Repensando la agresión entre adolescentes: una revisión de la teoría de estrategias de control de recursos en Latinoamérica(2021-08-22)La Teoría de Control de Recursos es un planteamiento con un poco más de 20 años en la literatura de la psicología del desarrollo. Esta sugiere que los seres humanos desplegamos estrategias coercitivas y/o estrategias prosociales para alcanzar nuestros objetivos sociales. Este marco conceptual ha logrado identificar que la conducta agresiva entre adolescentes es utilizada instrumentalmente para obtener estatus social. Sin embargo, estos estudios son escasos con poblaciones latinoamericanas, por lo que es necesario promoverlos para diseñar intervenciones contextualizadas para la agresión escolar. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Psychometric evaluation of the Brief-COPE Inventory and exploration of factors associated with perceived stress among Peruvian nurses(Multidisciplinary Digital Publishing Institute (MDPI), 2024-09-01)This study aimed to analyze the psychometric properties of the Brief-COPE Inventory and to determine its concurrent validity by examining its association with perceived stress among Peruvian nurses. Methods: A psychometric study was conducted with 434 Peruvian nurses to evaluate the psychometric properties of the Brief-COPE Inventory through confirmatory factor analysis. Three stepwise variable selection regression models were implemented. Results: The three-factor model of the Brief-COPE Inventory demonstrated adequate fit indices (root mean square error of approximation = 0.052, standardized root mean square residual = 0.068, and both the comparative fit index and the Tucker–Lewis index = 0.95). Additionally, the factors were significantly correlated (p < 0.001), and the reliability was adequate (ω = 0.90). Nurses reported a medium level of perceived stress, with associated factors including having received stress management training, fear of COVID-19, and problem-focused coping strategies (p < 0.05). Conclusion: This study confirms that the Brief-COPE Inventory is a valid tool for measuring coping strategies among Peruvian nurses due to its good model fit, excellent reliability, and concurrent validity with perceived stress. However, further research is needed to assess its validity in the specific areas of performance perceived by nursing professionals. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Psychometric assessment of the Communication Skills Scale among Peruvian nurses and factors associated with job insecurity(Multidisciplinary Digital Publishing Institute (MDPI), 2024-12-22)Background/Objectives: The aim of this study was to evaluate the psychometric properties of the Communication Skills Scale (CSS) among Peruvian nurses, as well as the factors associated with job insecurity during the COVID-19 pandemic. Methods: We explored five models of confirmatory factor analysis for the CSS and its four subscales and assessed the convergent validity and criterion validity of the scale by analyzing its connection with job insecurity through stepwise multiple regression. We used insights from a focus group for the cultural adaptation of the scale. In the psychometric phase, 225 nurses participated through a virtual survey. Results: The psychometric analysis revealed that the CSS and its subscales have a robust internal structure—similar to the original questionnaire—and are optimally reliable in the Peruvian population. Furthermore, the results show that job insecurity was associated with contract type, communication skills, empathy, and job satisfaction. Conclusions: The CSS and its subscales are valid and reliable to be applied to Peruvian nurses. Initiatives should be undertaken to strengthen communication skills and increase job satisfaction among nursing professionals by improving their working conditions, especially in times of crisis, to reduce job insecurity and promote well-being. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Emotional impact of COVID-19 and emotional eating and the risk of alcohol use disorder in Peruvian healthcare students(Multidisciplinary Digital Publishing Institute (MDPI), 2024-09-01)This study aimed to explore the association between the emotional impact of COVID-19 and emotional eating and the risk of alcohol use disorder among Peruvian health science students. Methods: We conducted a cross-sectional analytical study in which an online questionnaire was administered to 456 health science interns from four cities in Peru. We used the COVID-19 Emotional Impact Profile questionnaire, Mindful Eating Questionnaire, and Alcohol Use Disorders Identification Test. Spearman’s correlations were calculated and two multiple linear regression models were developed. Results: 68.4% of the participants were emotional eaters and 8.6% reported low-risk levels of alcohol use disorder. Based on the results of the first model, the overall emotional impact of COVID-19, being overweight or obese, depression and anxiety levels, and living with only one parent were factors associated with emotional eating. The results of the second model showed that the level of depression, living with just one parent, living alone, sex, and number of months as an intern were factors associated with the risk of alcohol use disorder. Conclusions: To reduce emotional eating and the risk of alcohol use disorder among interns, universities should implement interventions aimed at reducing the emotional impact of COVID-19 and provide nutritional counseling. - Some of the metrics are blocked by yourconsent settings

Methods: Psychometric study carried out in 434 Peruvian nurses to determine the psychometric properties by confirmatory factor analysis. Three stepwise variable selection regression models were implemented. Results: The three-factor of the Brief-COPE Inventory reported adequate fit (root mean square error of approximation = 0.052, standardized root mean square = 0.068, and both the comparative fit index and the Tucker–Lewis index = 0.95). Likewise, we found that its factors are correlated (p < 0.001) and that there is adequate reliability (ω= 0.90). Moreover, nurses showed a medium level of perceived stress and the following associated factors: sex, having received stress management training, fear of COVID-19, and problem-focused coping strategies (p < 0.05). Conclusion: This study proved that Brief-COPE Inventory is a valid tool for measuring coping strategies in Peruvian nurses because it has a good fit to the model, excellent reliability, and concurrent validity with perceived stress. However, further studies are required to evaluate its validity according to the nursing professionals’ perceived areas of performance. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Efectos de la pandemia y las medidas de confinamiento sobre la salud mental en población infantil de Chile(Pontificia Universidad Católica de Chile, 2023-07-03)The COVID-19 pandemic has evolved complex challenges especially for families with children and adolescents. The impact of the pandemics' confinement on mental health has been described as devastating, limiting the resources available to families and increasing caregivers' stress levels and demands on their efforts. This study showed the results of an online survey of caregivers, mothers or fathers, with at least one child between 0 and 11 years old who lived the first weeks of confinement throughout Chile. The variables associated with physical symptoms, anxiety, mood, disruptive behavior, sleep problems, low frustration tolerance, attentional difficulties, hyperactivity and regressive behaviors that are related to the psychological impact that the measure of confinement has had on children from 0 to 11 years of age were studied through a questionnaire quantifying their frequency by age group, identifying how these effects are expressed in relation to the vital stages of child development. The results indicate that the younger the age of the children (0 to 3 years) the greater the presence of disruptive behaviors, while the older the age (9 to 11 years) the greater the presence of symptoms such as sadness, anxiety, listlessness and sleep problems. The implications of these results are discussed in terms of policies and strategies to address them, which should consider both the developmental stage of the children and the main caregivers, given the protective role they can play in stressful situations. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, The impact of different adverse childhood experiences on the dimensions of emotional dysregulation in adults with major depression(Frontiers Media, 2025-01-01)Introduction: Adverse childhood experiences adversely affect the development of emotional regulation, yet their differential impact on discrete dysregulation dimensions in major depressive disorder remains underexamined. This study examines the relationship between adverse childhood experiences and emotional dysregulation, as well as its five dimensions. Methods: A total of 120 out-patients meeting the BDI-II cutoff for MDD completed the Childhood Trauma Questionnaire-SF (CTQ-SF) and the Difficulties in Emotion Regulation Scale (DERS). We first tested sex differences on DERS subscales (none emerged), then ran a multivariate multiple regression using Pillai's trace to assess the joint effects of the five CTQ-SF dimensions on the five DERS dimensions. Six follow-up linear regressions predicted each DERS subscale and the total DERS score from the CTQ-SF dimensions. Results: Physical abuse was the only CTQ dimension with a significant multivariate effect. In univariate models, emotional abuse predicted higher overall dysregulation and increased emotional dyscontrol, everyday interference, and emotional inattention, whereas greater physical abuse was associated with reduced everyday interference. Discussion: Emotional abuse appears to be the principal driver of both global and facet-specific emotion-regulation difficulties in adults with MDD, suggesting that interventions emphasizing impulse control, emotion awareness, and reduction of functional interference may be particularly beneficial for this subgroup. Limitations: The cross-sectional, selfreport design precludes causal inferences and may be subject to recall bias; future work should employ longitudinal, multimethod approaches to elucidate mechanisms and resilience factors.1
