La edad de inicio se ha señalado como un predictor crucial del consumo de alcohol en la adolescencia. Sin embargo, varios autores han advertido que se trata de un artefacto poco fiable que se explica por la tendencia a retrasar la edad de inicio a medida que aumenta la edad de los encuestados (forward telescoping o sesgo de memoria). Este estudio pretende comprobar si la edad de inicio es una medida aproximativa de la edad o un predictor del consumo de alcohol por sí mismo. Se utilizó un modelo de regresión jerárquica y la Macro Process para SPSS para probar el efecto de la edad de inicio (controlando la edad) en el consumo de alcohol y el papel mediador/moderador de la edad de inicio, el control parental y el sexo en el consumo de alcohol, respectivamente. Los resultados confirman el papel de la edad de inicio como predictor significativo del consumo de alcohol en los adolescentes ecuatorianos en lugar de artefacto. Además, la edad de inicio medió completamente el efecto de la edad en el consumo de alcohol, con frecuencia moderado por el sexo. Se discuten posteriormente las implicaciones prácticas.

Background: alcohol use is one of the main risk factors that leads to detrimental health effects and support for a transdiagnostic approach to alcohol use disorders is growing. However, the role of transdiagnostic predictors of problematic alcohol consumption in Ecuador are understudied. Objective: the aim of this study was to examine gender differences in psychological stress and inflexibility as transdiagnostic predictors of problematic alcohol consumption in a large sample of college students in Ecuador. Methods: a total of 7,905 college students (21.49years, SD=3.68; 53.75% females) were surveyed using the following standardized scales: alcohol Use Disorders Identification Test, Perceived Stress Scale-14, and Acceptance and Action Questionnaire (AAQ-7). Macro Process for SPSS (models 4 and 7) was used to analyze mediation and moderation effects. Results: reported alcohol consumption was significantly higher in men than women students. On the other hand, women reported significantly higher levels of perceived stress and psychological inflexibility than men students. Gender, age, psychological stress, and inflexibility were significant predictors of alcohol consumption. Moreover, psychological inflexibility mediated the impact of stress on alcohol consumption, particularly in women (for men b=0.065, 95% CI [0.048 to 0.083], for women b=0.070, 95% CI [0.051 to 0.089]). Discussion: results of this study support psychological stress and psychological inflexibility as critical transdiagnostic variables related to increased rates of alcohol consumption among Ecuadorian college students. These conclusions contribute to the development of transdiagnostic comprehensive programs, which encompasses promotive, preventive, and treatment services that allow to alleviate the burden of alcohol, as well as to enrich the growing research on alcohol consumption in this population from a gender perspective.

Prevention of alcohol consumption programs for children and youth: a narrative and critical review of recent publications
(Health Psychology, 2022) Sánchez Puertas, Rafael; Vaca Gallegos, Silvia; López Núñez, Carla; Ruisoto Palomera, Pablo; Ciencias de la Salud; Osasun Zientziak; Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa
Background: youth substance use is a public health problem globally, where alcohol is one of the drugs most consumed by children, and youth prevention is the best intervention for drug abuse. Objective: review the latest evidence of alcohol use prevention programs in empirical research, oriented to all fields of action among children and youth. Methods: a narrative and critical review was carried out within international databases (PsychInfo, Pubmed, Web of Science, and Scopus) in August 2021 and was limited to empirical studies that appeared in the last five years (2017-2021). A flow diagram was used according to the PRISMA statements. Empirical research articles in English with RCTs and quasi-experimental design that included alcohol, children, and young people up to 19 years of age (universal, selective, or indicated programs) were included. The authors examined the results and conceptual frameworks of the Prevention programs by fields of action. Results: twenty-two articles were found from four fields of action: school (16), family (2), community (2), and web-based (2), representing 16 alcohol prevention programs. School-based alcohol prevention programs are clinically relevant [Theory of Planned Behavior, Refuse, Remove, Reasons, Preventure, The GOOD Life, Mantente REAL, Motivational Interviewing (BIMI), Primavera, Fresh Start, Bridges/Puentes], they are effective in increasing attitudes and intentions toward alcohol prevention behavior, while decreasing social norms and acceptance of alcohol, reducing intoxication, and increasing perceptions with regards to the negative consequences of drinking. Discussion: This narrative and critical review provides an updated synthesis of the evidence for prevention programs in the school, family, community, and web-based fields of action, where a more significant number of programs exist that are applied within schools and for which would have greater clinical relevance. However, the prevention programs utilized in the other fields of action require further investigation.

Transdiagnostic model of psychological factors and sex differences in depression in a large sample of Ecuador
(Asociación Española de Psicología Conductual, 2022) Ruisoto Palomera, Pablo; López Guerra, Victor Manuel; López Núñez, Carla; Paladines Costa, María Belén; Sánchez Puertas, Rafael; Pineda Cabrera, Nairoby Jackeline; Ciencias de la Salud; Osasun Zientziak
Background/Objective: depression represents a leading cause of disability and a major contributor to the overall global burden of disease with women systematically reporting a higher prevalence than men. This study aimed to examine the predictive value and relation of three transdiagnostic psychological factors (perceived stress, psychological inflexibility and loneliness) on depression and its sex differences for the general population in a large sample of Ecuador. Method: a non-probabilistic and non-clinical sample of 16.074 people from across Ecuador were online surveyed using a cross-sectional design. The structural equation model was based on scores from standardized questionnaires as measures of depression, psychological perceived stress, psychological inflexibility, and loneliness. Results: women reported significantly higher levels of depression, mediated by differences in perceived stress, psychological inflexibility and loneliness. Perceived stress was the most important predictor of depression and mediated the effect of loneliness on depression. Complementarily, psychological inflexibility partially mediated the effect of perceived stress and loneliness on depression. The overall model accounted for the 78% of the total variance in depression. Conclusions: results of this study provide a novel and robust transdiagnostic model of sex differences on depression and insights on how to design effective programs for preventing depression targeting modifiable transdiagnostic risk factors.
