The role of interpretation biases and safety behaviours in social anxiety: an intensive longitudinal study.

BACKGROUND: Interpretation bias and safety behaviours (Safe-B) have been proposed as factors perpetuating social anxiety (SA). However, longitudinal research on how they contribute to SA in everyday life is scarce. AIM: The aim was to examine whether interpretation bias predicts daily Safe-B and SA. A mediated moderation was hypothesized, where the relationship between daily social stressors and Safe-B would be moderated by interpretation bias, and Safe-B, in turn, would mediate the association between stressors and SA levels. In addition, it was hypothesized that prior levels of SA would predict higher Safe-B use, especially in co-occurrence with stressors. METHOD: An intensive longitudinal design was employed, with 138 vocational training students (51% men, mean age 20.15 years). They completed initial measures of SA and interpretation bias and 7-day diaries with measures of social stressors, Safe-B, and SA. They reported SA levels two months later. RESULTS: Both stressors and interpretation bias in ambiguous situations predicted Safe-B, which in turn predicted daily SA levels. However, neither interpretation bias nor Safe-B predicted SA levels at the follow-up, and interpretation bias did not moderate the association between stressors and daily SA. In addition, the relationship between stressors and Safe-B was stronger in people with higher initial SA levels. CONCLUSIONS: The results suggest that Safe-B are a mechanism through which earlier SA levels and interpretation bias contribute to higher SA levels in daily life.

Negative self-talk in runners: Emotional intelligence and perceived stress as explanatory factors.

To optimize in the cognitive and emotional processes that appear in stressful situations in sports contexts is a relevant aspect to achieve a high level of performance. The present study aimed to analyze the relationship between perceived stress, emotional intelligence and negative self-talk in runners. It also aimed to determine whether emotional intelligence factors could play a protective role in this relationship. The sample consisted of 1071 runners from a race held in the Basque Country (Spain). The age of the participants was between 18 and 75 years (Mean = 41.59; SD = 9.95; 71.4% men). Participants completed an online survey days after the race. The results showed that perceived stress would be related to greater use of negative self-talk. In addition, evaluation of others' emotions and emotional regulation would also explain the occurrence of negative self-talk. Likewise, the interaction between perceived stress and appraisal of one's own emotions would explain the occurrence of negative self-talk, this relationship being stronger among those with lower scores on appraisal of one's own emotions. Results and practical implications of the findings are discussed.

Psychological Symptoms in Parents Who Experience Child-to-Parent Violence: The Role of Self-Efficacy Beliefs.

Previous research suggests that parents involved in child-to-parent violence (CPV) experience shame, judgment, and a lack of social support, often accompanied by feelings of self-blame and helplessness as well as a deterioration in their perception of self-efficacy and their parenting skills. All of these factors may impact parents' mental health. However, there is a research gap concerning the consequences of CPV among parents. Therefore, the objective of this study was to examine the relationship between CPV and psychological symptoms (i.e., depression, anxiety, hostility, obsessive-compulsive, interpersonal sensitivity, and somatization) in parents based on their perceptions of self-efficacy. The sample was composed of 354 participants: 177 parents (83.1% mothers) and their 177 children (53.4% boys; Mage = 13.27). CPV was reported by both parents and their children. In addition, parents reported their self-efficacy beliefs and psychological symptoms. The results showed that CPV was negatively associated with parents' psychological symptomatology, except for somatization. Moreover, self-efficacy beliefs explain part of the indirect association between CPV behaviors and psychological symptoms in parents. Overall, our findings provide evidence for the potential impact of CPV on mental health in parents and suggest the relevance of reinforcing their self-efficacy beliefs.

Dispositional mindfulness profiles in pregnant women: relationships with dyadic adjustment and symptoms of depression and anxiety.

Introduction: Pregnancy is a time of major transition that can be stressful for women. Dispositional mindfulness may protect individuals when they face stress. Recent studies have adopted a person-centered approach to examine the role of mindfulness by identifying subtypes of individuals based on their scores in five mindfulness facets. Latent profile analysis was used to identify different mindfulness profiles in a sample of pregnant women, and we explored the relationships between these profiles, depression and anxiety symptoms, and whether dyadic adjustment mediated these relationships. Method: A total of 535 women aged 18-45 years in their 26th week of pregnancy completed questionnaires regarding mindfulness, dyadic satisfaction and cohesion, and depression and anxiety symptoms. Results: Three profiles were identified: (1) low mindfulness (53.8%), (2) moderate mindfulness (34.3%), and (3) non-judgmentally aware (11.9%). The most adaptive profile was the non-judgmentally aware profile. Compared to the low mindfulness profile, the non-judgmentally aware profile and the moderate mindfulness profile were related to fewer symptoms of depression and anxiety, and these relationships were partly mediated by dyadic satisfaction. Discussion: These results suggest that analyzing each pregnant woman's mindfulness profile can improve the prevention of and interventions for anxiety and depression.

Longitudinal Associations Between Nonsuicidal Self-Injury, Depressive Symptoms, Hopelessness, and Emotional Dysregulation in Adolescents.

Nonsuicidal self-injury (NSSI) in adolescents has been associated with increased depressive symptomatology, hopelessness, and emotional dysregulation; however, few studies have examined longitudinal associations between NSSI and these problems. This study examines the longitudinal relationships among these variables in community adolescents and whether the pattern of relationships varies between boys and girls. The participants were 785 adolescents (57.1% girls) aged 13 to 18 years (M = 15.64; SD = 1.08) who completed self-reported measures of NSSI, depression, hopelessness, and emotional dysregulation at least once at two moments separated by 1 year. The longitudinal model was tested through structural equation modeling and multiple group analysis. NSSI predicted increased depressive symptoms, hopelessness, and emotional dysregulation; depressive symptoms predicted NSSI; hopelessness predicted depressive symptoms; and emotional dysregulation predicted depressive symptoms and hopelessness. The pattern was similar for girls and boys, although girls scored higher on all variables. The results underscore the important bidirectional associations between NSSI and other risk factors throughout adolescence. These findings will support prevention and interventions for NSSI and internalizing symptoms in adolescents in school and clinical settings.

HighlightsSometime in the last year, 38.4% of the participating adolescents reported nonsuicidal self-injury (NSSI). The girls scored significantly higher than the boys in NSSI annual presence, depression, hopelessness, and emotional dysregulation.NSSI in the past year increased depressive symptoms, hopelessness, and emotional dysregulation 1 year later; depressive symptoms predicted NSSI; hopelessness predicted depressive symptoms, and emotional dysregulation predicted an increase in depressive symptoms and hopelessness.The predictive model did not differ according to gender.

Are All Child-to-Parent Violence Profiles Associated with Exposure to Family Violence? Findings from a Sample of Spanish Adolescents.

Exposure to family violence (EFV) is proposed as a relevant antecedent of child-to-parent violence (CPV). However, both previous research and practitioner experience suggest that not all cases of CPV involve EFV. This study aimed to identify profiles of adolescents according to their degree of involvement in CPV and their EFV. A sample of 1647 adolescents (mean age = 14.30, SD = 1.21; 50.5% boys) completed measures of CPV, witnessing family violence, victimization by parents, permissive parenting, parental warmth, and several measures of cognitive and emotional characteristics. Latent profile analyses based on measures of CPV and family characteristics supported a four-profile solution. Profile 1 (82.2%) consisted of adolescents with very low scores on both CPV and exposure to family violence. Profile 2 (6.2%) was characterized by medium scores on psychological CPV and high EFV. Profile 3 (9.7%) was characterized by severe psychological CPV and very low EFV. Profile 4 (1.9%) included adolescents with the highest scores on CPV, including physical violence, and high EFV. These profiles were found to differ from each other according to several cognitive and emotional variables of the adolescents. Therefore, not all CPV profiles were associated with a history of EFV. The obtained profiles have implications for interventions.

The Protective Role of Dispositional Mindfulness on Cyber Dating Abuse: A 6-Month Longitudinal Study.

Dispositional mindfulness has been related to a decreased propensity to aggressive behaviors toward others, including dating partners. Nevertheless, research in the context of romantic relationships is scarce, based on cross-sectional designs and offline (face to face) aggression. Thus, this 6-month longitudinal study seeks to fill a gap in the literature by examining the predictive role of dispositional mindfulness facets (observing, describing, acting with awareness, non-judging, and non-reacting) in the perpetration of cyber dating abuse (CDA) behaviors in adolescents. The moderator role of the dispositional mindfulness facets in the perpetuation over time of cyber aggression toward the partner was also explored. Participants were 501 high school students (54.1% girls; mean age: 14.17 years, SD = 1.39) from different regions of Spain who completed self-report measures about CDA and dispositional mindfulness at two time points with a 6-month interval between them. Path analysis showed that the acting with awareness mindfulness facet predicted a decrease in the perpetration of CDA 6 months later. Moreover, non-reacting showed a moderator role in the perpetuation over time of CDA. In particular, adolescents with higher scores on non-reacting, evidenced a lower perpetuation of CDA. Mindfulness-based interventions can be a valuable tool in preventing cyber aggression that occurs in adolescent dating relationships.

Do testosterone and cortisol levels moderate aggressive responses to peer victimization in adolescents?

Aggressive reactions to peer victimization may be tempered by hormone levels. Grounded on the dualhormone hypothesis (DHH), which proposes that testosterone (T) is associated with aggressive behavior only when cortisol (C) is low, this study assessed whether the combination of T and C moderated adolescents' aggressive responses to peer victimization. The study involved 577 adolescents (50.4% girls, aged 12-17 years), who completed measures of online and offline victimization and perpetration of aggressive behavior in three waves over the course of one year. Moreover, they provided salivary samples to measure T and C levels. Multilevel analyses showed a three-way interaction between T, C, and victimization levels for both online and offline aggressive behaviors. In both cases, the adolescents with high T and high C or low T and low C responded with more aggressive behaviors when victimized or provoked by peers. The T/C ratio was only associated with aggressive behavior in the girls' sample. The results are opposite to those predicted by the DHH, but they are consistent with the findings of other studies that examined aggressive behaviors as reactions to provocations. These results suggest that some combinations of T and C predict higher aggressive reactions to peer victimization.

Longitudinal associations between dispositional mindfulness and addictive behaviors in adolescents. / Asociaciones longitudinales entre el rasgo de mindfulness y conductas adictivas en adolescentes.

Adolescence is a vulnerable period for the development of addictive behaviors, and substance use (SU) and problematic Internet use (PIU) typically start during this developmental stage. Dispositional Mindfulness (DM) has been proposed as a protective factor for adolescents against numerous psychological problems. Previous studies have suggested that the Observing facet of DM may moderate the other facets' roles. The objective of this study was to longitudinally analyze whether the facets of DM could predict lower levels of PIU and SU among adolescents, and to assess whether the Observing facet moderated the associations between the other facets of DM and addictive behaviors. A total of 836 participants aged 11 to 18 completed measures of PIU, SU, and the five facets of DM. The results indicated that Acting with Awareness predicted lower SU, Describing predicted an increase in both PIU and SU, and Non-judging marginally predicted lower PIU. Furthermore, Observing was beneficial against PIU when combined with high levels of Acting with Awareness, but was not when combined with high levels of Describing. The implications and future directions for the empirical study of DM against addictive behaviors are discussed.

La adolescencia es un período vulnerable para el desarrollo de conductas adictivas. El uso de sustancias (US) y el uso problemático de Internet (UPI) generalmente comienzan durante esta etapa de desarrollo. El mindfulness rasgo (MD) se ha propuesto como un factor protector para los y las adolescentes frente a numerosos problemas psicológicos. Estudios previos sugieren que la faceta Observar de MD puede moderar los roles de las otras facetas. El objetivo del presente estudio fue analizar longitudinalmente si las facetas de MD podían predecir niveles más bajos de UPI y US entre los y las adolescentes, y evaluar si la faceta Observar moderaba las asociaciones entre las otras facetas de MD y las conductas adictivas. Un total de 836 participantes de entre 11 y 18 años completaron medidas de UPI, US y las cinco facetas de MD. Los resultados indicaron que Actuar con conciencia predijo niveles más bajos de US, Describir predijo un aumento tanto de UPI como de US y No juzgar predijo marginalmente niveles más bajos de UPI. Además, la faceta Observar fue beneficiosa frente a UPI cuando se combinó con altos niveles de Actuar con conciencia, pero no fue beneficiosa cuando se combinó con altos niveles de Describir. Se discuten las implicaciones y direcciones futuras para el estudio empírico de MD frente a conductas adictivas.

The Association between exposure to COVID-19, internalizing symptoms, and Dispositional Mindfulness in Adolescents: a longitudinal pre- and during-pandemic study.

This study examined the association between contact with COVID-19 and internalizing symptoms in Spanish adolescents, and the moderation and mediation roles of dispositional mindfulness. Adolescents (N = 383; 58% female; Mage = 15.62, SD = 1.32) completed measures of dispositional mindfulness (MAAS-A) and internalizing symptoms (DASS-21), other stressors different from COVID-19, and contact with COVID-19 twice, in October 2019 and 2020. Three profiles emerged according to their contact with COVID-19: (1) little/no contact, (2) knowing someone close (outside home) who was infected, hospitalized, or died, and (3) being or someone at home being infected and/or hospitalized. Compared to little/no contact, both contact profiles predicted dispositional mindfulness and anxiety; and profile 2 predicted stress. Dispositional mindfulness mediated the association between both contact profiles and depression and stress. This study suggests that contact with COVID-19 predicts increased internalizing symptoms in adolescents, which could be partially explained by the decrease in mindfulness levels.

Problematic Internet use and Internet gaming disorder: Overlap and relationship with health-related quality of life in adolescents. / Uso problemático de Internet y trastorno de juego por Internet: Solapamiento y relación con la calidad de vida relacionada con la salud en adolescentes.

General Problematic Internet Use (GPIU) is a dysfunctional use of Internet handling and management in general. In contrast, Internet Gaming Disorder (IGD) is a specific behaviour linked to online videogames. Both problems are becoming common in adolescents, but they have hardly been studied simultaneously, and the joint relationship of the two constructs with Health-Related Quality of Life (HRQoL) is unknown. The general objective of this study is to analyse the relationship between GPIU and IGD and their association with HRQoL. The study is analytical and cross-sectional with 2,024 participants (46.4% boys, n = 939) from 16 schools of 7 Spanish regions. The mean age and standard deviation were 14.20±1.42, with a range of 11-18 years. The Spanish versions of the KIDSCREEN-10, the Revised Generalized and Problematic Internet Use Scale 2 and the Internet Gaming Disorder Scale were used. Of the total sample evaluated, 15.5% of the participants had high levels of GPIU, and 3.3% of video game players presented IGD. The dimensions of GPIU are strongly associated with those of IGD. HRQoL correlated significantly and negatively with all the dimensions of GPIU and IGD (p <.001). Participants who reported problems with GPIU or IGD, individually or conjointly, had significantly lower scores in HRQoL than those with no problems.

El Uso problemático general de Internet (GPIU) supone un uso disfuncional del manejo y la gestión de Internet en general. En cambio, el Trastorno de juego por Internet (IGD) es una conducta específica vinculada a los videojuegos en línea. Ambos problemas comienzan a ser frecuentes en adolescentes, pero apenas han sido estudiados simultáneamente ni se conoce el papel conjunto de ambos constructos sobre Calidad de vida relacionada con la salud (CVRS). El objetivo general de este estudio es analizar la relación entre el GPIU y el IGD y su asociación con la CVRS. El estudio es analítico y transversal con 2024 participantes (46,4% chicos, n = 939) procedentes de 16 colegios en 7 regiones españolas. La media de edad y desviación típica fue de 14,20±1,42 en un rango de 11-18 años. Se usaron las versiones españolas del KIDSCREEN-10, del Revised Generalized and Problematic Internet Use Scale 2 y del Internet Gaming Disorder Scale. Un 15,5% del total de la muestra evaluada reportó niveles altos de GPIU y un 3,3% de los jugadores de videojuegos presentó IGD. Las dimensiones del GPIU están altamente asociadas a las del IGD. La CVRS correlacionó significativa y negativamente con todas las dimensiones del GPIU y del IGD (p <,001). Los participantes que reportaron problemas en el GPIU o el IGD, individual o conjuntamente, presentan puntuaciones significativamente más bajas en la CVRS.

A Growth Mindset and Self-Affirmation Intervention to Reduce Violent and Risky Online Behaviors: The Moderating Role of Previous Victimization.

The Internet is the setting for several forms of violent and risky behavior among adolescents, such as cyberbullying, sexualized interactions with adults, sexting, and online dating violence. Often, these behaviors are responses to experiences of online victimization. This study examined the differential effects of a wise intervention (WI), combining growth mindset and self-affirmation strategies, on these behaviors for adolescents who had experienced victimization and those who had not. A sample of 1,085 adolescents (54.3% girls; ages 11-18 years) were randomized into two intervention conditions (WI and an anti-stress control intervention). They completed measures of violent and risky behaviors at pretest and at 3- and 6-month follow-ups and measures of victimization at pretest. The results of multilevel analyses indicated that the WI was beneficial for adolescents without experiences of victimization at pretest, as they displayed smaller increases in online peer aggressions, sexualized interactions with adults, and sexting than the adolescents in the control condition. However, the WI was not beneficial for adolescents with experiences of victimization at pretest. Moreover, the adolescents under the anti-stress control condition displayed better outcome. These findings suggest that previous victimization experiences of adolescents should be considered to select an appropriate intervention.

The Revised Child-to-Parent Aggressions Questionnaire: an Examination During the Covid-19 Pandemic.

Purpose: Child-to-parent violence (CPV) is an important type of family violence that has been relatively understudied. This study examined the main psychometric properties of the revised Child-to-Parent Aggression Questionnaire (CPAQ-R), which examines both violent behaviors against parents and reasons for these behaviors. The aims included identifying the dimensions of CPV and examining the magnitude of CPV during the COVID-19 pandemic. Methods: A sample of 1,244 adolescents (aged from 12 to 17) from several schools in the Basque Country completed the CPAQ-R. Several confirmatory factor analyses were conducted, including exploratory, confirmatory, exploratory structural equation modeling (ESEM), and bifactor analyses. Results: The data supported a bifactor ESEM model in which a general factor of violence against parents explained aggressions against both mothers and fathers. In addition, three reasons for the violence emerged: instrumental, reactive, and defensive reasons. Rates of CPV during the COVID-19 pandemic were high, with 16.5% of adolescents reporting reiterative aggressions against their parents. There were no differences between aggressions against mothers and fathers. Conclusions: The CPAQ-R is an adequate questionnaire for assessing CPV in adolescents. The confinement and restrictions placed on families during the COVID-19 pandemic may explain the high prevalence of CPV and shed light on possible differences related to the sex of the parents.

Interpretation Biases in Social Scenarios and Social Anxiety: The Role of Safety Behaviors.

BACKGROUND: Interpretation bias (IB) and safety behaviors (SB) are maintenance mechanisms of social anxiety (SA). However, few studies have examined the role of IB and SB together in explaining SA. The objective of this study was to determine whether SB explains the association between IB and SA. To evaluate these variables, the Adolescents' Interpretation and Beliefs Questionnaire (AIBQ 2.0) and the Social Phobia Safety Behaviors Scale (SPSBS) needed to be adapted for Spanish adolescents and young people. METHOD: 826 Spanish vocational training students (60% males, 14-28 years old) completed a measure of SA and the AIBQ 2.0 and SPSBS. RESULTS: Path analysis showed that IB in offline scenarios was associated with SA through SB. IB in offline situations, but not in online situations, was directly associated with SA. As expected, the AIBQ 2.0 showed a two-dimensional structure and good internal consistency. The SPSBS demonstrated a unidimensional structure and good internal consistency. CONCLUSIONS: In the absence of longitudinal studies, the data are compatible with the possible mediating role of SB in the association between IB and SA. Both instruments (AIBQ 2.0 and SPSBS) exhibited good psychometric properties for Spanish students.

Nonsuicidal Self-Injury Thoughts and Behavior in Adolescents: Validation of SITBI-NSSI.

BACKGROUND: The lack of knowledge about Nonsuicidal Self-Injury (NSSI) in Spanish adolescents, especially NSSI thoughts may be due to the paucity of NSSI assessment instruments with validity evidence in this sample. The aim of this study was to assess NSSI thoughts and behavior. In addition, the study examined the association between various NSSI features and suicidal behavior and included a preliminary validation of the new Self-Injurious Thoughts and Behaviors Interview - Non-Suicidal Self-Injury (SITBI-NSSI). METHOD: 685 Spanish adolescents between 13 and 18 years old (M = 15.58, SD = 1.08; 60.9% girls) completed measures of NSSI features and suicidal behavior. RESULTS: Among adolescents, 19% thought about self-injury, and 16.8% presented NSSI behaviors. The girls had higher levels of NSSI, as well as greater frequency, number of functions, methods, and suicidal thoughts and desire. Some of the functions, methods, and precipitants differed by sex. Those with ANS had a higher risk of suicidal behavior than the comparison group. The association of SITBI-NSSI with other measures supports the validity of the data. CONCLUSIONS: Most features of NSSI are similar to those found in Spanish and internationally. The SITBI-NSSI could facilitate the evaluation of NSSI in Spanish adolescents.

Emotion dysregulation and mindfulness in non-suicidal self-injury.

This study examined the association between mindfulness and engagement in non-suicidal self-injury (ENSSI) and whether emotion dysregulation explains this association. A secondary objective was to explore the difference between participants who engaged in a suicide attempt and those who only engaged in non-suicidal self-injury. A sample of 201 psychiatric patients (62.7% female; age range: 18-71 years old) participated in the study. The path analysis indicated that trait mindfulness was negatively associated with all emotion dysregulation dimensions and that one of these dimensions, impulse control difficulty, was associated with higher ENSSI. Moreover, impulse control difficulty was associated with increased odds of having attempted suicide. These findings suggest that mindfulness is a relevant construct to ENSSI with and without a suicide attempt. Future studies should investigate mindfulness-based interventions for ENSSI and the role played by the capacity to control impulses when experiencing negative emotions.

Understanding the Perpetuation of Cyberbullying Victimization in Adolescents: The Role of Executive Functions.

The consequences of cyberbullying victimization can lead to its perpetuation over time, initiating a vicious cycle. Thus, it is important to identify the factors that contribute to the persistence of victimization. This study aimed to examine some longitudinal mechanisms involved in the perpetuation of cyberbullying victimization in adolescents. The secondary aim was to study the protective role of executive functions (cognitive flexibility and selective attention) in this process, filling a gap in the literature. Sex differences were also studied. The sample consisted of 698 adolescents between 12 and 17 years of age (M = 14.59, SD = 1.36; 40.83% girls) from the Basque Country (Spain). Adolescents participated in a longitudinal study with three waves, in which 5-6 months elapsed between waves. The participants completed measures of executive functions in wave 1, of cyberbullying perpetration and depressive symptoms in waves 1 and 2, and of cyberbullying victimization in all three waves. The findings indicated that cyberbullying victimization was perpetuated through an increase of cyberbullying perpetration and depressive symptoms. Concerning executive functions, cognitive flexibility attenuated the impact of cyberbullying victimization on cyberbullying perpetration and depressive symptoms, and these in turn predicted lower levels of future victimization. Sex differences revealed that selective attention acted as a risk factor for cyberbullying victimization in girls and as a protective factor in boys. The results highlight the importance of considering mediating mechanisms involved in the perpetuation of cyberbullying victimization as well as the beneficial role played by cognitive flexibility in reducing the stability of cyberbullying victimization.

A Preventive Intervention to Reduce Risk of Online Grooming Among Adolescents.

Sexual abuse of adolescents by adults on the Internet is a severe risk with negative consequences for the victims. However, there is an important gap in the development of preventive interventions to address this problem. This study evaluated the efficacy of a brief (less than one hour) educational intervention on online grooming (less than one hour) in reducing adolescents' sexual interaction behaviors with adults when they are sexually solicited. A sample of 856 Spanish adolescents (48% girls, ages 11-17 years) was randomized into two intervention conditions (educational intervention about online grooming and a resilience control intervention). Adolescents completed measures of online sexual solicitation by adults and sexualized interactions with adults at pretest and at three- and six-month follow-ups. Measures of their knowledge about online grooming were taken at pretest, postintervention, and at three- and six-month follow-ups. The results of multilevel analyses indicated that the intervention reduced sexualized interactions when adolescents were sexually solicited by adults (ß = -.16, SD = .07, t = -2.44, p = .015). Moreover, the intervention increased adolescents' knowledge about online grooming over time (ß = 1.95, SD = .19, t = 10.52, p < .001). These findings suggest that a brief educational intervention about online grooming may be a promising, low-cost intervention to reduce the risks of sexual abuse on the Internet.

El abuso sexual de adolescentes por parte de adultos en Internet (grooming online) es un riesgo grave con consecuencias negativas para las víctimas. Sin embargo, existe un importante vacío en el desarrollo de intervenciones preventivas para abordar este problema. Este estudio evalúa la eficacia de una intervención educativa breve (menos de una hora) sobre el grooming online para disminuir las conductas de interacción sexual de los adolescentes con adultos cuando son solicitados sexualmente. Una muestra de 856 adolescentes españoles (48% chicas; edades entre 11 y 17 años) fue aleatorizada en dos condiciones de intervención (intervención educativa sobre el grooming online y una intervención control de resiliencia). A los adolescentes se les aplicaron medidas de solicitud sexual online por parte de adultos e interacciones sexualizadas con adultos en la línea base y en los seguimientos a tres y seis meses. Además, se tomaron medidas sobre conocimiento del grooming online en la línea base, después de la intervención y en los seguimientos a tres y seis meses. Los resultados de los análisis multinivel indicaron que la intervención redujo las interacciones sexualizadas cuando los adolescentes eran solicitados sexualmente por adultos (ß = -.16, SD = .07, t = -2.44, p = .015). Por otra parte, la intervención aumentó los conocimientos de los adolescentes sobre grooming online a lo largo del tiempo (ß = 1.95, SD = .19, t = 10.52, p < .001). Estos resultados sugieren que una breve intervención educativa sobre grooming online puede ser prometedora y de bajo coste para reducir los riesgos de abuso sexual en Internet.

Developmental Moderators of a Single-Session Incremental Theory of Personality Intervention on Aggressive Behavior.

This study examines two indicators of developmental level (testosterone and grade) as moderators of the effects of a single-session incremental theory of personality intervention on both traditional and online aggressive behaviors. A sample of 535 Spanish adolescents (boys: 50%; age: 12-17 years) participated in a double-blind, randomized controlled trial. Participants were randomized to receive the incremental theory of personality intervention or an alternative educational control condition. The intervention consisted of teaching the belief that people can change. Aggressive behaviors were measured at baseline, one-week posttest, and six-month and twelve-month follow-ups. Testosterone level moderated the effectiveness of the intervention for online aggressive behavior so that, among adolescents with low and medium testosterone levels, those in the control group increased online aggressive behavior, whereas adolescents receiving the intervention remained at similar levels of perpetration. Grade moderated the effectiveness of the intervention on both forms of aggressive behavior, being only effective in Grade 8. Overall, the findings indicate that some preventative interventions can be more effective among adolescents with lower levels of development.

Cyberbullying victimization and nonsuicidal self-injury in adolescents: The role of maladaptive schemas and dispositional mindfulness.

BACKGROUND: Previous research has found associations between cyberbullying victimization and nonsuicidal self-injury (NSSI) in adolescents. Exploration of the possible mediating variables involved is necessary to support intervention with victims. OBJECTIVE: This study examined whether depression and early maladaptive schemas (EMS) mediate the association between cyberbullying victimization and NSSI, along with the potential protective role of dispositional mindfulness. PARTICIPANTS AND SETTING: A total of 742 Spanish adolescents (50.20% girls) between 12 and 17 years old (M = 14.58; SD = 1.00) participated in the final sample. METHOD: Participants completed measures of cyberbullying victimization, NSSI, EMS, depression, and mindfulness facets. Mediational models moderated by facets of mindfulness were tested. RESULTS: Cyberbullying victimization was associated with NSSI through increased depression and EMS. Acting with awareness buffered the association between cyberbullying victimization and NSSI, whereas non-judging increased the association between cyberbullying victimization and depression. CONCLUSIONS: Cybervictimization is associated with NSSI. The mindfulness facet of acting with awareness plays a protector role. Interventions in NSSI and cyberbullying could benefit from these findings.
