Changes in cannabis use in Spanish consumers during the COVID-19 lockdown according to gender, age, living situation and addiction level. / Cambios en el consumo de cannabis en consumidores españoles durante el confinamiento por la COVID-19 según sexo, edad, situación de convivencia y nivel de adicción.

The objective was to analyze the changes in cannabis use during lockdown considering sex, age, living situation and level of addiction. This descriptive and non-probabilistic study used a convenience sample of 208 participants with ages between 18-57 years (64.3% men; mean age = 31.39 years), that reported consuming cannabis. The frequency of distinct typologies of cannabis use was analyzed and the level of addiction with the Cannabis Abuse Screening Test (CAST). An online survey was used to collect the variables under study. A total of 25% consumers increased their spliff (marijuana mixed with tobacco) consumption, 11.9% increased their joint (marijuana cigarette) consumption and 11.8% increased their hashish spliff consumption. Men had higher levels of cannabis addiction, however, during lockdown they reduced their marijuana spliff consumption while both men and women increased their joint consumption. Marijuana spliff consumption showed a greater increase in the 25-29 age group, in those living with people other than relatives or a partner, alone, or with a partner and was reduced mainly in those living with parents or other relatives. The living alone 18-24 years old group, and the living with parents 35-44 years old group showed higher levels of cannabis addiction (CAST). The rate of dependent consumers who increased their marijuana spliff consumption (49%) doubled compared to consumers with no addiction and moderate addiction. Regarding joints, consumption was 1.5 times higher than for moderate addiction consumers and three times higher than those with no addiction. The risk of cannabis addiction increased in certain groups during lockdown.

El objetivo fue analizar el consumo de cannabis durante el confinamiento según sexo, edad, situación de convivencia y nivel de adicción. Estudio descriptivo no probabilístico con una muestra de conveniencia de 208 participantes con edades entre 18-57 años (64,3% hombres; edad media = 31,39 años) que reportaron consumir cannabis. Se analizó la frecuencia de distintas tipologías de consumo de cannabis y el nivel de adicción con el Cannabis Abuse Screening Test (CAST). La recogida de datos se realizó mediante encuesta online. El 25% de consumidores aumentó su consumo de porros de marihuana mezclada con tabaco; el 11,9% de cigarros de marihuana; y el 11,8% de porros de hachís mezclado con tabaco. Los hombres presentaron mayor nivel de adicción al cannabis. Sin embargo, redujeron su consumo de porros durante el confinamiento. Hombres y mujeres incrementaron su consumo de cigarros de marihuana. El consumo de porros se incrementó mayormente en el grupo de 25-29 años, entre quienes convivían con personas distintas a familiares y pareja, vivían solas, o en pareja; y se redujo entre quienes vivían con progenitores o familiares. Mostraron mayor nivel de adicción al cannabis (CAST) el grupo entre 18-24 años que vive solo y el grupo entre 35-44 años que convive con sus progenitores. Los consumidores con dependencia que incrementan su consumo de porros (49%) fue dos veces superior respecto a los grupos sin adicción y con adicción moderada. El consumo de cigarros de marihuana (20,8%) fue 1,5 veces superior que para adicción moderada y más del triple que para sin adicción. El riesgo de adicción a cannabis aumentó en ciertos grupos durante el confinamiento.

Age slowing down in detection and visual discrimination under varying presentation times.

The reaction time has been described as a measure of perception, decision making, and other cognitive processes. The aim of this work is to examine age-related changes in executive functions in terms of demand load under varying presentation times. Two tasks were employed where a signal detection and a discrimination task were performed by young and older university students. Furthermore, a characterization of the response time distribution by an ex-Gaussian fit was carried out. The results indicated that the older participants were slower than the younger ones in signal detection and discrimination. Moreover, the differences between both processes for the older participants were higher, and they also showed a higher distribution average except for the lower and higher presentation time. The results suggest a general slowdown in both tasks for age under different presentation times, except for the cases where presentation times were lower and higher. Moreover, if these parameters are understood to be a reflection of executive functions, these findings are consistent with the common view that age-related cognitive deficits show a decline in this function.

The Effect of Corrective Feedback on Performance in Basic Cognitive Tasks: An Analysis of RT Components.

The current work examines the effect of trial-by-trial feedback about correct and error responding on performance in two basic cognitive tasks: a classic Stroop task (n = 40) and a color-word matching task (n = 30). Standard measures of both RT and accuracy were examined in addition to measures obtained from fitting the ex-Gaussian distributional model to the correct RTs. For both tasks, RTs were faster in blocks of trials with feedback than in blocks without feedback, but this difference was not significant. On the other hand, with respect to the distributional analyses, providing feedback served to significantly reduce the size of the tails of the RT distributions. Such results suggest that, for conditions in which accuracy is fairly high, the effect of corrective feedback might either be to reduce the tendency to double-check before responding or to decrease the amount of attentional lapsing.

The effects of age and emotional valence on recognition memory: an ex-Gaussian components analysis.

The aim of this work was to study the effects of valence and age on visual image recognition memory. The International Affective Picture System (IAPS) battery was used, and response time data were analyzed using analysis of variance, as well as an ex-Gaussian fit method. Older participants were slower and more variable in their reaction times. Response times were longer for negative valence pictures, however this was statistically significant only for young participants. This suggests that negative emotional valence has a strong effect on recognition memory in young but not in old participants. The τ parameter, often related to attention in the literature, was smaller for young than old participants in an ex-Gaussian fit. Differences on the τ parameter might suggest poorer attentional performance in old participants.

Risk and Protective Factors Associated with Drug Use in Healthcare Professionals: A Systematic Review.

Healthcare professionals are exposed to stressful situations that may favor substance use vulnerability. This systematic review aims to synthesize the risk and protective factors associated with use, abuse, and dependence of alcohol, tobacco, psychoactive drugs, and cannabis in healthcare professionals. Following PRISMA recommendations, a systematic search was performed in PsycINFO, Web of Science, PubMed/MEDLINE, Embase, Scopus, and Cochrane Library. The search yielded 1523 studies, of which 19 were selected. The identified risk factors were demographic factors (i.e. male gender, and single/divorced marital status), psychopathological factors, social factors, positive attitudes toward drugs, unhealthy lifestyle habits, the COVID-19 pandemic, and the coexistence of the use of several substances. The protective factors were demographic factors (i.e. ethnicity and having dependent children), healthy lifestyle habits, and workplace anti-drug policies (i.e. restriction of tobacco use). These findings highlight the need for preventive actions against drug use in healthcare professionals to improve their health and reduce the possible negative impact on their healthcare practice. Knowledge of modifiable risk and protective factors allows their incorporation as components in preventive actions, and non-modifiable factors (e.g. demographic variables) may contribute to the detection of groups of greater vulnerability to propose selective prevention actions in this population.

Changes in tobacco and e-cigarette consumption in Spanish university students during the COVID-19 lockdown: Identification of vulnerable groups.

INTRODUCTION: The objective of this study was to determine the changes in tobacco consumption in Spanish university students during the lockdown in 2020, and to identify vulnerable groups based on gender, age, and living situation. METHODS: This was a cross-sectional descriptive study. From a sample of 1540 Spanish university students, 19.9% (n=306; 77.6% women; mean age=30.9 years; SD=8.3) reported having consumed tobacco. The frequency and average daily consumption of cigarettes and electronic nicotine delivery systems (ENDS) before the pandemic and during lockdown were analyzed. RESULTS: A total of 97.1% of students consumed only cigarettes, 2.9% only ENDS, and 3.3% were dual consumers. During lockdown, cigarette consumption was significantly reduced (5.3 before; 4.0 during; t(71)=3.6255; p<0.001) in the youngest group (aged 18-24 years). However, women daily users significantly increased their consumption (t(149)= -2.5461; p<0.05) and so did the 35-44 years age group (t(32)= -2.2285; p<0.05). Cigarette consumption significantly increased in those who were living alone (5.6 to 7.2; Z= -2.351; p<0.05) and with a partner (7.2 to 8.0; t(97)= -2.3771; p<0.05), but decreased in those who were living with their parents or other relatives (6.2 to 4.5; t(101)=3.4298; p<0.001). A total of 17.0% ceased consumption during lockdown, mainly women, younger students (aged 18-24 years), and those who lived with their parents. None of the people who used cigarettes daily during the pre-pandemic period stopped smoking during lockdown. CONCLUSIONS: Younger university students and those living with their parents decreased their tobacco use during the lockdown. Potentially vulnerable groups at risk of increasing their consumption were women who consumed tobacco daily before the pandemic and students aged 35-44 years who lived alone or with their partner.

Problematic Internet Use, Depressive Symptomatology and Suicidal Ideation in University Students During COVID-19 Confinement.

BACKGROUND: The aim was to estimate the rate of PIU in Spanish university students during the lockdown, taking sex and age into account, and to analyze its relationship with depression and suicidal ideation. METHOD: 921 university students (55% women) from 18 to 30 years old (M = 24.8 years; SD = 3) participated. RESULTS: The results showed that 21% of the participants presented PIU, 25.1% moderate depression, 2.1% severe depression, and 6.6% suicidal ideation. The 18 to 21-year-old age group presented the highest rate of PIU (37.8%). A positive correlation was observed between PIU and depression (r = .38; p (241.813) = -8.21; < d = .78) in university students with PIU (M = 9.8; SD = 5.1) than those without it (M = 6.4; SD = 4.1). The rate of severe depression was six times greater (χ2 (3) = 73.25; p < .001) in undergraduates with PIU (6.2%) than those without PIU (0.8%). Moreover, 3.6% of university students with PIU presented suicidal ideation. CONCLUSIONS: These findings establish the association between PIU and depression and suicidal ideation in the university population, providing novel contributions for prevention policies.

Cannabis Use in Young and Adult University Students Before and During the COVID-19 Lockdown, According to Gender and Age.

The objectives were: (a) to establish cannabis use prevalence in university students; (b) to determine the changes in consumption of cannabis between prior to and during lockdown. Problematic consumption, gender, and age were taken into account to establish risk groups. Of 1,472 participants between 18-54 years (M = 27.51), 8.01% reported using cannabis before and/or during lockdown (56.6% male). The Cannabis Abuse Screening Test (CAST) was used to detect cannabis abuse. The main form of consumption was spliffs (89.9%). The mean of spliffs consumed per day decreased during lockdown, but was only significant in male and in the 18-24 group. This decrease was also significant for all three levels of CAST problematic use. Users with moderate addiction and dependence reduced their average number of spliffs consumed per day during lockdown to a greater extent than those without addiction. These findings establish target groups of prevention interventions in the university.

[Effects of cannabis use on attention and memory in adolescent population: a systematic review.] / Efectos del consumo de cannabis en la atención y la memoria en población adolescente: una revisión sistemática.

OBJECTIVE: Cannabis is an illegal drug whose use has increased in recent years, especially among adolescents. Despite its popularity, its use and abuse brings with it health consequences, being greater if consumption occurs in the adolescent stage, since the brain is in full development. The objective of this systematic review was to determine the effects of cannabis use on cognitive functions of attention and memory in adolescent population. METHODS: A systematic review of the literature was carried out in the main search portals (Pubmed, Web of Science, SciELO, Cochrane) referring to the last 10 years, following the PRISMA criteria. The systematic search strategy was carried out in the period from March to May 2021, applying the PICO method and the PEDro scale to guarantee the methodological quality of the included studies. RESULTS: Both attention and memory are affected by cannabis use; however, memory functions improve with abstinence, not being so for attention. Memory deficits are an indicator of therapeutic abandonment of addiction treatment. In relation to psychosocial interventions aimed at improving memory, the contingency management, educational interventions and motivational interviewing have not been shown to be effective on the effects of substances. Working memory training offers positive results, although not clinically significant. Finally, memory deficits are an indicator of therapeutic abandonment of pharmacological treatment for cannabis addiction. Therefore, research is needed aimed both at reducing the side effects of drugs on memory processes and at establishing to what extent memory deficits associated with cannabis use can facilitate therapeutic abandonment. CONCLUSIONS: More research is necessary, considering the dual consumption of cannabis-tobacco and the effects that both substances may have jointly and separately on attention and memory processes.

OBJETIVO: El cannabis es una droga ilegal cuyo consumo se ha visto incrementado en los últimos años, especialmente en población adolescente. A pesar de su popularidad, su uso y abuso trae consigo consecuencias para la salud, siendo mayores si el consumo se produce en la etapa adolescente, ya que el cerebro se encuentra en pleno desarrollo. El objetivo de esta revisión sistemática fue determinar los efectos del consumo de cannabis en las funciones cognitivas de atención y memoria en población adolescente. METODOS: Se llevó a cabo una revisión sistemática de la literatura en los principales portales de búsqueda (Pubmed, Web of Science, SciELO, Cochrane) referida a los últimos diez años, siguiendo los criterios PRISMA. La estrategia de búsqueda sistemática se realizó en el periodo de tiempo comprendido entre los meses de marzo a mayo de 2021, aplicándose el método PICO y la escala PEDro para garantizar la calidad metodológica de los estudios incluidos. RESULTADOS: Tanto la atención como la memoria se ven afectadas por el consumo de cannabis; sin embargo, la memoria mejora su funcionamiento con la abstinencia, no ocurriendo lo mismo con la atención. Los déficits de memoria son un indicador de abandono terapéutico del tratamiento para la adicción. En relación con las intervenciones psicosociales orientadas a la mejora de la memoria, tanto el manejo de contingencias como las intervenciones educativas y la entrevista motivacional no se han mostrado efectivas sobre los efectos de las sustancias. El entrenamiento en la memoria de trabajo ofrece resultados positivos, aunque clínicamente no significativos. Finalmente, los déficits de memoria son un indicador de abandono terapéutico del tratamiento farmacológico para la adicción al cannabis, por lo que se precisa investigación orientada tanto a reducir los efectos secundarios de los fármacos sobre los procesos mnésicos como a establecer en qué medida los déficits de memoria asociados al consumo de cannabis pueden facilitar el abandono terapéutico. CONCLUSIONES: Se precisa mayor investigación, considerando el consumo dual de cannabis-tabaco y los efectos que ambas sustancias pueden tener, conjuntamente y por separado, sobre los procesos de atención y memoria.

Depression, Suicidal Ideation, and Consumption of Psychotropic Drugs During Lockdown by COVID-19 According to Gender and Age.

The objective was to analyze the relationship between depression and suicidal ideation and psychotropic drugs use during COVID-19 lockdown in adult population considering gender and age. The method used is a descriptive and non-probabilistic study, with a convenience sampling of 3780 participants (70.1% female), aged 18-64 years (M = 37.8). 18.3% participants presented depression and 5.1% exhibited suicidal ideation. The depression rate for female was double (21.4%) than male and 5 times higher (30.2%) for the youngest participants (18-24 years old) compared to oldest (55-64 years old), being this rate triple in suicidal ideation (9%). Depression correlated positively with tranquilizers and sleeping pills' consumption; and suicidal ideation did so with tranquilizers and sedatives. The rate of tranquilizer users was 8 times higher for severe depression compared to those who did not present depression, 5 times higher for sleeping pills, and 6 times higher for sedatives. The rate of tranquilizer users exhibiting suicidal ideation was more than triple than those who did not present suicidal ideation, between 3 and 4 times higher for sleeping pills, and almost 7 times higher for sedatives. The higher the level of depression and suicidal ideation during lockdown, the greater the consumption of psychotropic drugs. The consumption of psychotropic drugs should be monitored in people with depression and suicidal ideation during periods of crisis.

[Impact of confinement measures on the Covid-19 pandemic on alcohol risk consumption.] / Impacto de las medidas de confinamiento durante la pandemia de Covid-19 en el consumo de riesgo de alcohol.

OBJECTIVE: The public health strategies adopted for the containment of COVID-19 have generated psychosocial stressors that act as risk factors for alcohol consumption. The objectives of this study were to establish whether alcohol risk consumption varied during COVID-19 confinement, and how these variations manifested as a function of different sociodemographic variables. METHODS: The study was conducted during confinement with 3,779 participants in Spain. We used an online survey with sociodemographic variables (sex, age and employment situation) and AUDIT-C. Frequency and mean difference analysis were performed (Student t, ANOVA and Kruskal-Wallis) to establish intra-group variations before the pandemic compared to during confinement, and intergroup for each time period, reporting effect size. RESULTS: Alcohol risky consumption presented high prevalence rates before confinement (25,9% of alcohol consumers), showing a general decrease during confinement (15,1%), both in men (X2=224,829; p<0,001) and women (X2=214,324; p<0,001). Women had higher risk consumption rates both before the pandemic (X2=13,124; p<0,001; d=1,067) and during confinement (X2=26,316; p<0,001; d=2,85); however, men reported higher score in AUDIT-C before the pandemic (t(2343)=-7,887; p<0,001; d=0,322) and during confinement (t(2343)=-5,664; p<0,001; d=0,231). Considering age, significant differences in prevalence among groups were found before the pandemic (X2=22,889; p<0,001) and during confinement (X2=38,302; p<0,001), with the age range 18-24 showing less prevalence. Differences among age groups were also found in the risky consumption scores during confinement (F(5,2338)=43,849; p=0,001), increasing with age. With regards to the employment situation, differences before the pandemic (KW(5,2933)=13,467; p=0,019; E2R=0,44), and during confinement (KW(5,2933)=149,818; p<0,001; E2R=0,51) were also found. Self-employed workers showed a higher score in alcohol risky consumption with respect to full-time employees (p=0,047). CONCLUSIONS: The alcohol risky consumption decreased in a generalized way during the confinement by COVID-19, but the changes in prevalence and risk index were dependent on sociodemographic variables. It is recommended that these findings are considered in the design of public health policies and strategies.

OBJETIVO: Las estrategias de salud pública adoptadas para la contención del COVID-19 han generado estresores psicosociales que actúan como factores de riesgo del consumo de alcohol. Los objetivos del estudio fueron establecer si el consumo de riesgo de alcohol varió durante el confinamiento por COVID-19 durante los meses de abril y mayo de 2020, y cómo estas variaciones se manifestaban en función de distintas variables sociodemográficas. METODOS: El estudio se desarrolló durante el confinamiento con 3.779 participantes en España. Se utilizó una encuesta online con variables sociodemográficas (sexo, edad y situación laboral) y el AUDIT-C. Se realizó análisis de frecuencias y diferencia de medias (t de Student, ANOVA y Kruskal-Wallis) para establecer las variaciones a nivel intragrupo entre antes de la pandemia y durante el confinamiento, e intergrupo para cada periodo temporal, reportando tamaño del efecto. RESULTADOS: El consumo de riesgo de alcohol presentó una prevalencia elevada antes del confinamiento (25,9% de los consumidores de alcohol), mostrando un descenso durante el confinamiento (15,1%), tanto en hombres (X2=224,829; p<0,001) como en mujeres (X2=214,324; p<0,001). Las mujeres presentaron una mayor prevalencia de consumo de riesgo antes de la pandemia (X2=13,124; p<0,001; d=1,067) como durante el confinamiento (X2=26,316; p<0,001; d=2,85); sin embargo, los hombres reportaron mayores puntuaciones que las mujeres en el AUDIT-C antes de la pandemia (t(2343)=-7,887; p<0,001; d=0,322) y durante el confinamiento (t(2343)=-5,664; p<0,001; d=0,231). A nivel de edad, se encontraron diferencias significativas de prevalencia entre los distintos grupos antes de la pandemia (X2=22,889; p<0,001) y durante el confinamiento (X2=38,302; p<0,001), siendo el rango de 18-24 años el de menor prevalencia. También se observaron diferencias entre los grupos de edad en las puntuaciones de consumo de riesgo durante el confinamiento (F(5,2338)=43,849; p=0,001), aumentando conforme es mayor la edad. Respecto a la situación laboral, existen diferencias tanto antes de la pandemia (KW(5,2933)=13,467; p=0,019; E2R=0,44), como durante el confinamiento (KW(5,2933)=149,818; p<0,001; E2R=0,51). Ser trabajador autónomo mostró una mayor puntuación de consumo de riesgo de alcohol con respecto a ser trabajador a tiempo completo (p=0,047). CONCLUSIONES: El consumo de riesgo de alcohol desciende de manera generalizada durante el confinamiento por COVID-19, pero los cambios en prevalencia y probabilidad de ser consumidor de riesgo de alcohol son dependientes de variables sociodemográficas. Se recomienda contemplar estos hallazgos en el diseño de políticas y estrategias de salud pública.

Age and Living Situation as Key Factors in Understanding Changes in Alcohol Use during COVID-19 Confinement.

(1) The aim of the present study was to evaluate and characterize changes in alcohol use during the COVID-19 confinement in a sample of Spanish adults, analyzing their age and living situation as defining life cycle variables. (2) Method: Data from 3779 individuals were collected through a set of online surveys. AUDIT-C was used to measure the frequency of consumption, the average daily consumption, intensive consumption, risky consumption, and Standard Drink Units. (3) Results: Although alcohol consumption during confinement showed a significant general decline, age revealed important differences, with the decline being more pronounced in adults from 18 to 29 years old. The living situation also showed significant differences. The largest decreases in alcohol consumption were found in those who lived with their parents or other relatives, whereas those who lived alone or with a partner even increased their level of consumption. In addition, the data show a significant interaction between these two variables and gender. (4) Conclusions: Age and cohabitation processes are key factors in understanding the life situation of each individual during confinement and, consequently, in explaining consumption patterns. The results obtained provide interesting recommendations for designing prevention policies in both normal and crisis circumstances, emphasizing the need to understand alcohol use from a psychosocial perspective.

Changes in Alcohol Consumption Pattern Based on Gender during COVID-19 Confinement in Spain.

(1) The goal of this study was to analyze the prevalence and pattern of alcohol consumption (frequency of consumption, average daily consumption, and risky consumption) before and during confinement due to the coronavirus disease (COVID-19) in the adult population and based on gender. (2) Methods: Data from 3779 individuals were collected via a set of online surveys. The AUDIT alcohol consumption questions (AUDIT-C) were used to measure the frequency of consumption, the average daily consumption, intensive consumption, risky consumption, and standard drink units. (3) Results: During confinement, the prevalence of alcohol consumption declined in both males and females, but only intensive consumption showed significant differences, with a greater reduction in males. The number of females who consumed alcohol four or more times per week doubled, whereas the number of males who did so was multiplied by a factor of 1.5; in both females and males, the percentage who presented intensive consumption doubled. The percentage of females with risky consumption was higher than that of males both before and during confinement. In addition to gender, the interaction between age and the employment situation explain consumption before and during confinement. (4) Conclusions: During confinement due to COVID-19, alcohol consumption declined in both sexes, but alcohol-risk consumers increased their frequency of use. The interaction between gender, age, and employment situation was related to these changes. These findings are relevant for guiding public health and health-risk management policies related to alcohol consumption in environmental situations similar to COVID-19.

Consumo de alcohol durante el COVID-19 en Latinoamérica según edad y situación de empleo / Alcohol consumption during COVID-19 in Latin America according to age and employment situation

Esta investigación evaluó el consumo de alcohol en población adulta Latinoamericana y del Caribe latino durante el confinamiento por COVID-19, atendiendo a la edad y situación laboral. Diseño no probabilístico con muestreo por conveniencia, con una muestra de 4975 participantes. Se analizó edad, situación laboral y consumo de alcohol durante el confinamiento y retrospectivamente antes de la pandemia. Los resultados muestran que independientemente del país, los jóvenes de 18-29 años disminuyeron el consumo durante el confinamiento; mientras que el mayor aumento fue en adultos de 45-54 años. Los trabajadores a tiempo completo consumieron más que las personas desempleadas. Empleados a tiempo completo y a tiempo parcial, disminuyeron su consumo durante el confinamiento. Trabajadores por cuenta propia mostraron un consumo de alcohol significativamente superior al de empleados a tiempo completo y a tiempo parcial, durante el confinamiento. Es importante impulsar políticas de prevención del consumo de alcohol en el ámbito laboral. (AU)

This research evaluated alcohol consumption in the Latin American and Latin Caribbean adult population during COVID-19 confinement, taking into account age and employment status. Non-probabilistic design with convenience sampling, with a sample of 4975 participants. Age, employment status and alcohol consumption were analyzed during confinement and retrospectively before the pandemic. The results show that regardless of the country, young people aged 18-29 decreased consumption during confinement; while the largest increase was in adults aged 45-54 years. Full-time workers consumed more than unemployed people. Full-time and part-time employees decreased their consumption during confinement. Self-employed workers showed significantly higher alcohol consumption than full-time and part-time employees during confinement. It is important to promote policies to prevent alcohol consumption in the workplace. (AU)

Background: The aim was to estimate the rate of PIU in Spanish university students during the lockdown, taking sex and age into account, and to analyze its relationship with depression and suicidal ideation. Method: 921 university students (55% women) from 18 to 30 years old (M = 24.8 years; SD = 3) participated. Results: The results showed that 21% of the participants presented PIU, 25.1% moderate depression, 2.1% severe depression, and 6.6% suicidal ideation. The 18 to 21-year-old age group presented the highest rate of PIU (37.8%). A positive correlation was observed between PIU and depression (r = .38; p < .001), with a significantly higher mean score on the PHQ-9 (t(241.813) = -8.21; p < .001; d = .78) in university students with PIU (M = 9.8; SD = 5.1) than those without it (M = 6.4; SD = 4.1). The rate of severe depression was six times greater (χ2(3) = 73.25; p < .001) in undergraduates with PIU (6.2%) than those without PIU (0.8%). Moreover, 3.6% of university students with PIU presented suicidal ideation. Conclusions: These findings establish the association between PIU and depression and suicidal ideation in the university population, providing novel contributions for prevention policies.(AU)

Antecedentes: El objetivo fue estimar la tasa de PIU en universitarios españoles durante el confinamiento, considerando sexo y edad, y analizar su relación con depresión e ideación suicida. Método: Participaron 921 estudiantes universitarios (55% mujeres) de 18 a 30 años (M = 24.8 años; SD = 3). Resultados: Los resultados mostraron que el 21% presentaron PIU; 25.1% depresión moderada; 2.1% depresión severa; y 6.6% ideación suicida. El grupo de 18 a 21 años presentó la mayor tasa de PIU (37.8%). Se observó una correlación positiva entre PIU y depresión (r = .38; p < .001), con una puntuación media significativamente mayor en el PHQ-9 (t(241.813) = -8.21; p < .001; d = .78) en universitarios con PIU (M = 9.8; SD = 5.1) frente a los que no la tienen (M = 6.4; SD = 4.1). La tasa de depresión severa fue seis veces mayor (χ2(3) = 73.25; p < .001) en los universitarios con PIU (6.2%) en comparación con los que no tenían PIU (0.8%). El 3.6% de los universitarios con PIU presentó ideación suicida. Conclusiones: Estos hallazgos establecen la asociación entre PIU y depresión e ideación suicida en población universitaria, brindando aportes novedosos para las políticas de prevención.(AU)
