BACKGROUND AND OBJECTIVE: This study investigated: (1) the prevalence and development of 2 receptive (sexually explicit Internet material [SEIM] use and sexual information seeking) and 2 interactive (cybersex and general social networking site [SNS] use) online behaviors in adolescence; (2) whether development of these behaviors predict adolescents’ body and sexual self-perceptions; and (3) whether parental strategies regarding adolescents’ Internet use reduce engagement in sex-related online behaviors. METHODS: Four-wave longitudinal data among 1132 seventh- to 10th-grade Dutch adolescents (mean age at wave 1: 13.95 years; 52.7% boys) were collected. Developmental trajectories of sex-related online behaviors were estimated by using latent growth curve modeling. Self-perception outcomes at wave 4 and parental strategies predicting online behaviors were investigated by adding regression paths to growth models. RESULTS: Boys occasionally and increasingly used SEIM. Patterns for girls’ SEIM use and boys’ and girls’ sexual information seeking and cybersex were consistently low. SNS use, however, was a common, daily activity for both. Higher initial levels and/or faster increases in sex-related online behaviors generally predicted less physical self-esteem (girls’ SNS use only), more body surveillance, and less satisfaction with sexual experience. Private Internet access and less parental rule setting regarding Internet use predicted greater engagement in sex-related online behaviors. CONCLUSIONS: Although most sex-related online behaviors are not widespread among youth, adolescents who engage in such behaviors are at increased risk for developing negative body and sexual self-perceptions. Particular attention should be paid to adolescents’ SNS use because this behavior is most popular and may, through its interactive characteristics, elicit more critical self-evaluations. Prevention efforts should focus on parents’ role in reducing risky sex-related online behaviors.

This study used a person-centered approach to examine whether different developmental trajectories of boys’ and girls’ use of sexually explicit Internet material (SEIM) exist, which factors predict these trajectories, and whether sexual behavior develops differently for adolescents in these trajectories. A combination of latent class growth analysis on SEIM use and latent growth curve analysis on sexual behavior was used on four-wave longitudinal data of 787 eighth through tenth grade Dutch adolescents. Among boys, four SEIM use trajectories were identified, which were labeled Nonuse/Infrequent Use, Strongly Increasing Use, Occasional Use, and Decreasing Use. Among girls, a large Stable Nonuse/Infrequent Use and smaller Strongly Increasing Use and Stable Occasional Use trajectories were distinguished. Higher initial levels and/or stronger increases in SEIM use were predicted by demographic, social contextual, personal, and media use characteristics, including a stronger sexual interest, a higher degree of perceived realism regarding sexualized Internet content, and more permissive sexual attitudes. Moreover, initial levels of and, to some extent, developmental changes in sexual behavior varied for boys and girls in the different SEIM use trajectories. Whereas some adolescents showed concurrent low levels, or parallel strong increases in SEIM use and sexual behavior, a subgroup of boys decreased their SEIM use while increasing their sexual behavior.

Sex-Related Online Behaviors, Perceived Peer Norms and Adolescents' Experience with Sexual Behavior: Testing an Integrative Model

Suzan M. Doornwaard; Tom ter Bogt; Ellen Reitz; Regina J. J. M. van den Eijnden

Research on the role of sex-related Internet use in adolescents’ sexual development has often isolated the Internet and online behaviors from other, offline influencing factors in adolescents’ lives, such as processes in the peer domain. The aim of this study was to test an integrative model explaining how receptive (i.e., use of sexually explicit Internet material [SEIM]) and interactive (i.e., use of social networking sites [SNS]) sex-related online behaviors interrelate with perceived peer norms in predicting adolescents’ experience with sexual behavior. Structural equation modeling on longitudinal data from 1,132 Dutch adolescents (Mage T1 = 13.95; range 11-17; 52.7% boys) demonstrated concurrent, direct, and indirect effects between sex-related online behaviors, perceived peer norms, and experience with sexual behavior. SEIM use (among boys) and SNS use (among boys and girls) predicted increases in adolescents’ perceptions of peer approval of sexual behavior and/or in their estimates of the numbers of sexually active peers. These perceptions, in turn, predicted increases in adolescents’ level of experience with sexual behavior at the end of the study. Boys’ SNS use also directly predicted increased levels of experience with sexual behavior. These findings highlight the need for multisystemic research and intervention development to promote adolescents’ sexual health.

This study gives an overview of Project STARS (Studies on Trajectories of Adolescent Relationships and Sexuality), a four-wave longitudinal study of 1297 Dutch adolescents. First, the sample, measures and four sub-projects are described. Second, hierarchical regression analyses were conducted to examine how key variables from the individual domain (impulsivity), parent domain (parent–adolescent relationship quality), peer domain (involvement with peers) and media domain (time spent on social networking sites), and their interactions predict changes in the experience with sexual behaviour of adolescents across time. Results showed that higher levels of impulsivity, lower quality of relation with parents, more frequent involvement with peers and more time spent on social networking sites at baseline predicted increases in sexual experience of adolescents over a subsequent 1.5-year time period. No interaction effects among the domains were found. The findings highlight the significance of a multi-domain approach to the study of adolescent sexual development.

This study aimed at determining whether adolescents and young adults use music as an agent of consolation when dealing with daily sorrow and stress. We furthermore tested whether three aspects of music listening, i.e., the music itself, its lyrics, and experiences of closeness to artists and fans, were experienced as comforting. Third, we explored whether consolation through music listening was related to music use and psychological problems. Overall, 1,040 respondents, age 13–30 years (M = 20.3, 70.7% female), responded to items measuring listening hours, music importance, music preferences, positive and negative affects elicited by music (PANAS), internalizing and externalizing problems, and consolation through music. Slightly over 69% reported that they (definitely) use music as a source of consolation. Furthermore, female respondents and respondents with higher levels of anxiousness/depression and lower levels of aggression sought consolation by music more often. The same result emerged for respondents with a preference for chart pop music, for those who found music important, and for those with stronger emotional reactions to music. Music’s consoling effects were reported as resulting particularly from the sound and texture of the music itself, from attribution of personal meaning to music’s lyrics, and, to a lesser extent, from perceptions of closeness to artists and other listeners.

Experiment to test how sexualized media exposure affects later attention allocation.Participants watched a sexual or control video before completing dot and word tasks.All participants showed selective attention for explicitly displayed sexual cues.Participants in sexual video conditions were quicker to detect hidden sexual cues.Results may contribute to a better understanding of how sexual schemas are formed. This study examined whether exposure to sexualized media influences the subconscious process of attention allocation to subsequently encountered stimuli. One hundred twenty-three participants (61females) between 18 and 23years (Mage=19.99years) watched a 3-min video clip containing either neutral, sexually more explicit, or sexually less explicit imagery, before completing a dot detection task measuring selective attention for explicitly displayed sexual stimuli and a word search task measuring attention toward hidden sexual cues. Results of the dot detection task indicated that participants in all conditions were slower to detect the dot in trials including sexual stimuli, suggesting absorption by these stimuli. Results of the word search task indicated that participants in the two sexual video conditions, compared to participants in the neutral video condition, were quicker to detect a sexual word in the matrix, albeit only if they completed this task before the dot detection task. There were no differences in the number of sexual words found between video conditions. Our findings point out the importance of studying effects of sexualized media exposure on subconscious cognitive processes in young people, as such effects can provide us insights into how sexualized media content is processed and how sexual schemas are formed and strengthened.

The Internet offers adolescents unique opportunities to actively shape their own sexual media environment. The aim of this study was to gain in-depth insight into Dutch adolescents’ motives, perceptions, and reflections toward Internet use for (a) finding information or advice related to romance and sexuality; (b) searching for and viewing pornographic or erotic material; and (c) romantic and sexual communication (i.e., cybersex/sexting). Data were collected through 12 Web-based focus groups (36 adolescents aged 16 to 19 years, 72.2% girls) and analyzed through three stages of open, axial, and selective coding. The themes that emerged from the focus-group discussions suggest that sex-related Internet use is a complex and ambivalent experience for adolescents. Sex-related Internet use seems an increasingly normalized and common phenomenon. Participants perceived the Internet as a useful source of sexual information, stimulation, inspiration, and communication. Yet they discussed a range of negative consequences and risks related to sex-related online behaviors, particularly concerning pornography’s potential to create unrealistic expectations about sex and sexual attractiveness. Participants generally believed they had the necessary skills to navigate through the online sexual landscape in a responsible way, although they believed other young people could be influenced inadvertently and adversely by sex-related online content.

Research on how dark personality traits develop and relate to risky behaviors and family relations during adolescence is scarce. This study used a person-oriented approach to examine (a) whether distinct groups of adolescents could be identified based on their developmental profiles of callous-unemotional (CU), grandiose manipulative (GM), and dysfunctional impulsivity (DI) traits and (b) whether these groups differ in their problem behaviors and parent–adolescent relationship quality. Latent class growth analyses on 4-wave data of 1,131 Dutch adolescents revealed 3 personality profiles: (1) a dark impulsive group (13.9%), with high scores on all 3 traits (CU, GM, and DI) that were stable over time; (2) an impulsive group (26.1%), with high and increasing levels of impulsivity and relatively low scores on CU and GM; and (3) and a low risk group (60.0%), with relatively low levels on all 3 personality characteristics, with impulsivity decreasing over time. Compared with adolescents in the low risk group, adolescents in the dark impulsive and impulsive groups reported higher initial levels of substance use, sexual risk behaviors, permissive sexual attitudes, parent–adolescent conflict, and lower parent–adolescent satisfaction, as well as greater increases in sexual risk behavior over time. Compared with adolescents in the impulsive group, those in the dark impulsive group showed the highest levels of risk behaviors. Hence, dark personality traits coupled with impulsivity may be indicative of an earlier and more severe trajectory of problem behaviors that may differ from the trajectory of youth who are only impulsive.

Aim To extend the scholarly debate on (a) whether or not the compulsive use of games and social media should be regarded as behavioral addictions (Kardefelt-Winther et al., 2017) and (b) whether the nine DSM-5 criteria for Internet gaming disorder (IGD; American Psychiatric Association [APA], 2013) are appropriate to distinguish highly engaged, non-disordered users of games and social media from disordered users, this study investigated the impact of engaged and disordered use of games and social media on the psychosocial well-being and school performances of adolescents. Methods As part of the Digital Youth Project of the University of Utrecht, a three-wave longitudinal sample of 12- to 15-year-old adolescents (N = 538) was utilized. Three annual online measurements were administered in the classroom setting, including IGD, social media disorder, life satisfaction, and perceived social competence. Schools provided information on students’ grade point average. Results The symptoms of disordered use of games and social media showed to have a negative effect on adolescent’s life satisfaction, and the symptoms of disordered gaming showed a negative impact on adolescents’ perceived social competence. On the other hand, heavy use of games and social media predicted positive effects on adolescents’ perceived social competence. However, the heavy use of social media also predicted a decrease in school performances. Several gender differences in these outcomes are discussed. Conclusion The findings propose that symptoms of disordered use of games and social media predict a decrease in the psychosocial well-being and school performances of adolescents, thereby meeting one of the core criteria of behavioral addictions.

Abstract Aim: The aim of the present study was to document the relationship between automatic and explicit parenting cognitions and alcohol use in adolescents. In addition, we examined whether this relationship was dependent on parental alcohol use. Method: A convenience sample of 59 parents (57.63% mothers, 59.32% younger than 50 years) with children between 14 and 18 years (58.93% girls) completed the Relational Responding Task (RRT) prior to a paper-and-pencil questionnaire. Results: The relationship between automatic parenting cognitions as measured by the RRT and the frequency of adolescent alcohol intake among drinkers was significant, χ²(1) = 7.74, p < 0.01, even after controlling for the predictive validity of explicit parenting cognitions. The prevalence of alcohol use was related to explicit parenting cognitions (OR = 0.223, p < 0.001) but not automatic parenting cognitions. Conclusion: This study is the first to demonstrate that automatic parenting cognitions as measured by the RRT can be used as a predictor of alcohol use in adolescents who have initiated drinking, even after controlling for explicit parenting cognitions. This study provides the starting point of a much broader research program aimed at uncovering the relationship between automatic parenting cognitions and offspring behavior, also beyond the domain of alcohol use.
