RESUMO

Although media effect studies have quite extensively investigated the association between pornography use and gendered attitudes, some questions remain. The present study aimed to address two of these questions by exploring how gendered attitudes and gender beliefs may be influenced by gender typicality and pornography use. First, the literature has not yet accounted for individual differences based on gender typicality. Second, the influence of pornography use on gender beliefs going beyond pornography's script application is understudied. This online cross-sectional study (N = 1,440, Mage = 23.86, SD = 4.79) contributes to the field by investigating the indirect association between pornography use and acceptance of gender norm violation through gendered attitudes and the moderating role of gender typicality. Acceptance of gender norm violation was measured via vignettes describing a school context in which a teacher and a student violated gender norms. Findings indicated that gendered attitudes negatively relate to the acceptance of gender norm violation. Moreover, compared to women, men's pornography use indirectly relates to lower acceptance rates through gendered attitudes. Additionally, for men, specific levels of gender typicality and atypicality form a strengthening and buffering role, respectively. This applies to the association between pornography use and gendered attitudes as well as to the indirect relationship of pornography use with acceptance of gender norm violation. These findings suggest that pornography use may also affect gender beliefs that are unrelated to the scripts present in pornography. Future studies should take into account the type of preferred pornography and unravel the specific impact of women's pornography use.

RESUMO

Trait negative affectivity and trait extraversion/positive affectivity are predictive of both responses to affect and depressive symptoms in adolescence. Furthermore, differences in the use of responses to affect are associated with different levels of depressive symptoms. Despite the central role of media content in adolescents' daily lives, responses to affect have not yet been extended to affect in this media content. It is thus unclear whether trait affectivity is predictive of responses to affective media content, and whether such media response styles are predictive of depressive symptoms. A 3-wave longitudinal panel study with 3-month intervals among 318 adolescents (Mage = 16.5 years, SDage = 1.11, 72.5% boys) investigated the mediating role of media response styles in associations between trait affectivity and depressive symptoms. Trait negative affectivity predicted media rumination and media dampening, yet only media rumination predicted greater levels of depressive symptoms over time. Trait positive affectivity was associated with concurrent media distraction and media-enhancing. The media response styles did not mediate the associations between trait affectivity and depressive symptoms over time. These findings suggest that individuals higher in trait negative affectivity tend to engage in maladaptive emotion regulation strategies during sad media content consumption, whereas adolescents higher in trait positive affectivity turn to more adaptive strategies during sad or happy media content consumption. Yet, media response styles are not robustly associated with depressive symptoms over time.

RESUMO

Emerging evidence highlights the intricate link between identity and one's body, however, integrative longitudinal research on this identity-body interplay is lacking. The current study used three-wave longitudinal data (Time 1: N = 403; 52.1% female; Mage = 14.85, SD = 0.89, range = 13-19 years) spanning two years (2019-2021; T1 and T2 being pre-pandemic, T3 peri-pandemic) to identify identity trajectory classes and examine their co-development with negative and positive body image and various body-related variables (i.e., sociocultural pressures, internalization of appearance ideals, self-objectification, appearance comparison, and eating disorder symptoms). First, four identity classes emerged using latent class growth analysis (achievement, moratorium, carefree diffusion, and troubled diffusion). Second, using multigroup latent growth curve modeling, adolescents in less adaptive identity trajectory classes (i.e., engaging less in pro-active processes and more in ruminative processes) displayed higher levels of negative body image and body-related symptoms. The current study testified to the clinically meaningful associations linking identity formation to adolescents' body image and other body-related symptoms.

RESUMO

Entertainment media consumed by adolescents have been criticized for their stereotyped depictions of sexual relationships. This longitudinal study among 182 boys and 218 girls from Belgium tests reciprocal relationships between adolescents' acceptance of gendered sexual roles and their exposure to music television and online pornography over three waves. The study innovates by including a fourth wave, approximately 5 years after Wave 3, when the participants had reached emerging adulthood, allowing to study long-term associations across the two developmental stages. Results first showed that adolescents who watched more music television than their same-aged peers reported a stronger acceptance of rape myths in emerging adulthood. Second, the link between adolescents' music television viewing and acceptance of rape myths in emerging adulthood was an indirect relationship through adolescents' acceptance of gendered sexual roles during adolescence. Third, adolescents' exposure to online pornography relative to their same-aged peers did not predict their acceptance of gendered sexual roles or rape myths in emerging adulthood. Fourth, gender and age differences could not be investigated due to model fit problems and are suggested to be examined in future research. Implications of the long-term consequences of adolescents' media use are discussed.

RESUMO

INTRODUCTION: Scholars suggest that social networking sites such as Facebook offer adolescents an ideal setting for engaging in relationship maintenance behaviors. Despite these suggestions, it remains an open question whether adolescents' online relationship maintenance behaviors can improve aspects of positive friendship quality, such as feelings of closeness. Additionally, it is unclear whether adolescents' feelings of closeness can motivate them to engage in online relationship maintenance behaviors. The aim of this two-wave longitudinal panel study was to investigate the reciprocal relations between Facebook relationship maintenance behaviors (FRMB) and adolescents' closeness to friends. METHOD: A sample of 12- to 18-year-old Flemish adolescents (NTime1 = 1840) filled out a paper-and-pencil survey twice within a six month-interval. We estimated cross-lagged structural equation models in AMOS to test the reciprocal relations between FRMB, closeness to friends, and receiving positive Facebook reactions. To test whether the hypothesized relations were moderated by gender and/or age, we conducted multiple group comparison tests. RESULTS: Findings revealed that FRMB and adolescents' closeness to friends were reciprocally related over time: FRMB positively predicted adolescents' closeness to friends and closeness to friends positively predicted FRMB. In addition, receiving positive Facebook reactions mediated these reciprocal relations. CONCLUSION: By revealing that receiving positive Facebook reactions mediates the reciprocal relationships between FRMB and adolescents' closeness to friends, we now better understand how FRMB can increase adolescents' closeness to friends and how increased closeness to friends can enhance adolescents' FRMB. The discussion focuses on the understanding of these findings, directions for future research, and key limitations.

RESUMO

OBJECTIVE: Adolescents' snacking habits are driven by both explicit reflective and implicit hedonic processes. Hedonic pathways and differences in sensitivity to food rewards in addition to reflective determinants should be considered. The present study evaluated the feasibility and impact of a mobile phone-delivered intervention, incorporating explicit reflective and implicit rewarding strategies, on adolescents' snack intake. DESIGN: Adolescents (n 988; mean age 14·9 (sd 0·70) years, 59·4 % boys) completed a non-randomized clustered controlled trial. Adolescents (n 416) in the intervention schools (n 3) were provided with the intervention application for four weeks, while adolescents (n 572) in the control schools (n 3) followed the regular curriculum. Outcomes were differences in healthy snacking ratio and key determinants (awareness, intention, attitude, self-efficacy, habits and knowledge). Process evaluation data were collected via questionnaires and through log data of the app. RESULTS: No significant positive intervention effects on the healthy snack ratio (b=-3·52 (se 1·82), P>0·05) or targeted determinants were observed. Only 268 adolescents started using the app, of whom only fifty-five (20·5 %) still logged in after four weeks. Within the group of users, higher exposure to the app was not significantly associated with positive intervention effects. App satisfaction ratings were low in both high and low user groups. Moderation analyses revealed small positive intervention effects on the healthy snack ratio in high compared with low reward-sensitive boys (b=1·38 (se 0·59), P<0·05). CONCLUSIONS: The intervention was not able to improve adolescents' snack choices, due to low reach and exposure. Future interventions should consider multicomponent interventions, teacher engagement, exhaustive participatory app content development and tailoring.

RESUMO

Sociocultural models of body image posit that the media and peers play a role in early adolescents' body dissatisfaction. Introducing a sociocultural perspective on youth sexualization, the present three-wave panel study (N = 968, Mage  = 11.30) sought to examine the role of tween television and peer appearance conversations in early adolescents' body surveillance and self-objectification over time. Special attention was given to the mediating role of media internalization in these relationships. The results showed evidence for a reciprocal interaction between media internalization and peer appearance conversations and identified this reciprocal interaction as the underlying mechanism linking tween television exposure to higher levels of body surveillance and self-objectification 1 year later. Implications for body image and media literacy programs are discussed.

RESUMO

Inconsistent results have been reported concerning the relationships between SNS usage and loneliness. The current two-wave panel study with a one year interval examined the possibility of reciprocal and curvilinear relationships between active public Facebook use and adolescents' social/emotional loneliness. Belgian adolescents from fifteen high schools participated (N = 1188, 55% male). The results showed a U-shaped relationship between (1) active Facebook use and social/emotional loneliness and (2) emotional loneliness and active Facebook use. Specifically, active Facebook use predicted decreased social/emotional loneliness among low to moderate users, while among heavy users, increased levels of social/emotional loneliness were predicted by active Facebook use. Emotional loneliness predicted higher active Facebook use among lonely adolescents. At the same time, emotional loneliness predicted decreased active Facebook use among adolescents who did not feel lonely. These findings stress to consider different types of loneliness, and reciprocal and curvilinear relationships in future social media research.

RESUMO

Although media exposure has been related to cognitive preoccupation with appearance, research rarely investigated adolescents' behavioral self-sexualization. To address this gap, the present study among 12- to 16-year-olds (N = 1527; 50.2% girls) in Austria, Belgium, Spain, and South-Korea (1) investigates whether different types of media use relate to self-sexualization, (2) explores the explanatory value of rewarded appearance ideals, and (3) considers culture and gender as moderating factors. Despite cultural variation, a general trend of increasing self-sexualization with social media use and magazine reading appeared across the countries. Moreover, women's magazine reading and rewards were related to self-sexualization among all the girls across the countries, which suggests that girls may be more vulnerable to the examined effects. Overall, this study provides a better understanding of the unique contribution of specific media genres to youth's self-sexualization and points at the importance of social media use in girls' and boys' engagement in sexualizing appearance behaviors across four countries.

RESUMO

Adolescents' snack choices could be altered by increasing the reinforcing value (RV) of healthy snacks compared with unhealthy snacks. This study assessed whether the RV of fruit increased by linking it to a reward and if this increased RV was comparable with the RV of unhealthy snacks alone. Moderation effects of sex, hunger, BMI z-scores and sensitivity to reward were also explored. The RV of snacks was assessed in a sample of 165 adolescents (15·1 (sd 1·5) years, 39·4 % boys and 17·4 % overweight) using a computerised food reinforcement task. Adolescents obtained points for snacks through mouse clicks (responses) following progressive ratio schedules of increasing response requirements. Participants were (computer) randomised to three experimental groups (1:1:1): fruit (n 53), fruit+reward (n 60) or unhealthy snacks (n 69). The RV was evaluated as total number of responses and breakpoint (schedule of terminating food reinforcement task). Multilevel regression analyses (total number of responses) and Cox's proportional hazard regression models (breakpoint) were used. The total number of responses made were not different between fruit+reward and fruit (b -473; 95 % CI -1152, 205, P=0·17) or unhealthy snacks (b410; 95 % CI -222, 1043, P=0·20). The breakpoint was slightly higher for fruit than fruit+reward (HR 1·34; 95 % CI 1·00, 1·79, P=0·050), whereas no difference between unhealthy snacks and fruit+reward (HR 0·86; 95 % CI 0·62, 1·18, P=0·34) was observed. No indication of moderation was found. Offering rewards slightly increases the RV of fruit and may be a promising strategy to increase healthy food choices. Future studies should however, explore if other rewards, could reach larger effect sizes.

RESUMO

Sexualizing media content is prevalent in various media types. Sexualizing media messages and portrayals emphasize unattainable body and appearance ideals as the primary components of sexual desirability. The internalization of these ideals is positively related to self-objectification and sexual body consciousness. In turn, self-objectification and sexual body consciousness affect adolescents' sexual behavior, albeit in opposing directions. While objectifying self-perceptions are linked to higher levels of sexual behavior, body consciousness during physical intimacy is linked to lower levels of sexual behavior. Based on this knowledge, the present three-wave panel study of 824 Belgian, predominant heterosexual adolescents (M age = 15.33; SD = 1.45) proposes a dual-pathway model that investigates two different pathways through which the internalization of media ideals may impact adolescents' sexual behavior. An inhibitory pathway links media internalization to lower levels of sexual behavior through sexual body consciousness, and a supportive pathway links media internalization to higher levels of sexual behavior through self-objectification. Structural equation analyses supported the proposed dual-pathway, showing that the impact of media internalization on adolescents' sexual behavior proceeds through an inhibitory pathway and a supportive pathway. Regarding the supportive pathway, media internalization (W1) positively predicted sexual behavior (W3), through valuing appearance over competence (W2). Regarding the inhibitory pathway, media internalization (W1) positively predicted body surveillance, which, in turn, positively predicted sexual body consciousness (all W2). Sexual body consciousness (W2) is negatively related to sexual behavior (W3). From a sexual developmental perspective, these findings emphasize the importance of guiding adolescents in interpreting and processing sexualizing media messages.

RESUMO

Research suggests that sexualizing media messages are present in teen media and negatively affect young girls' body image. Yet, it is unknown whether exposure to teen television programs is associated with girls' engagement in appearance management behaviors. Two-wave longitudinal data among 785 girls (Mage = 11.65 years) were collected. Results show that teen television exposure was longitudinally related to appearance management, while the reverse relation was not supported. Approximately half of the girls indicated to manage their appearance to some extent, and 13- to 14-year-old girls were more likely to invest in their appearance than younger girls. Thirty percent of those who did not manage their appearance at the start of the study indicated to have initiated appearance management 6 months later. Frequent viewers were four times, three times, and twice as more likely to style their hair, wear heels, and apply make-up compared to non-viewers. CONCLUSION: The current study showed that teen media exposure plays a role in young girls' appearance management. The findings point to a need to teach young girls about stereotypical messages in media content directed towards them. Prevention efforts should focus on girls who frequently watch teen media. What is Known: • Sexualizing media messages are present in teen media. • Gender identity development is one of the key tasks during adolescence. What is New: • Tween television exposure predicts 9- to 14-year-old girls' engagement in appearance management over time. • Engagement in appearance management behaviors did not predict 9- to 14-year-old girls' exposure to tween television programs.

RESUMO

Three-and-a-half decades on, no cure or vaccine is yet on the horizon for HIV, making effective behavior change communication (BCC) the key preventive strategy. Despite considerable success, HIV/AIDS BCC efforts have long been criticized for their primary focus on the individual-level field of influence, drawing on the more reductionist view of causation at the individual level. In view of this, we conducted a series of studies that employed a household survey, field experiment, and textual content analysis, and explored the macro-social-level effects of HIV/AIDS-related media and messages on HIV/AIDS cognitive and affective outcomes in Ethiopia. Against a backdrop of epidemiological and socioecological differences, urban versus rural residence has emerged as an important community-level factor that impacts HIV/AIDS-related media and message consumption processes and associated outcomes. The central thread crossing through the six studies included in this paper demonstrates that urban and rural people in high HIV prevalence contexts differ in their concern about and information needs on HIV/AIDS, HIV/AIDS-related media use, and HIV/AIDS-related cognitive and affective outcomes, as well as in their reaction to differently designed/framed HIV prevention messages. This paper proposes that HIV prevention media and message effects in high epidemic situations should be considered from a larger community-level perspective and calls for a socioecological approach to AIDS communication in the hard-hit sub-Saharan Africa. With a number of concrete recommendations to current and future HIV/AIDS BCC efforts in the region, the study joins an emerging body of health communication literature and theorizing that suggests the need to consider media and message effects from a macro-social perspective.

RESUMO

Early adolescents (N = 1,591; Mage  = 11.698; SD = 0.892) participated in a two-wave panel study (6-month interval) to examine the longitudinal association between appearance-focused magazine exposure and social appearance anxiety. We revealed that magazine exposure positively correlated with the internalization of appearance ideals and the attribution of social rewards to attractiveness which, in turn, related to social appearance anxiety. Internalization and attribution of social rewards formed a reinforcing spiral; once internalized, early adolescents associate positive things with appearance ideals (e.g., peer acceptance) and the perception of rewards increases early adolescents' inclination to internalize ideals. Given the adverse consequences of social appearance anxiety, the findings warrant research on the role of media in the occurrence of social appearance anxiety.

RESUMO

Individuals who are more strongly invested in their appearance, appearance schematics, have a tendency to engage in appearance-related comparison. Appearance schematicity consists of two components. The self-evaluative component concerns the degree to which appearance is central to self-worth, referred to as dysfunctional appearance beliefs. Motivational salience refers to the engagement in behaviors designed to enhance appearance, such as body surveillance. Based on a three-wave panel survey of 973 Flemish preadolescents (Mage = 11.15, SD = 1.13) we found that the motivational and self-evaluative components had a different impact on media internalization. For preadolescents who engaged in more body surveillance, watching television resulted in more media internalization. For preadolescents who had fewer dysfunctional appearance beliefs, watching television resulted in more media internalization. These findings suggest that appearance schematicity is an important susceptibility variable in the relationship between TV-exposure and media internalization, and emphasize the importance of investigating individual dispositions beyond gender differences.

RESUMO

BACKGROUND: Although previous research found a positive association between sensitivity to reward (SR) and adolescents' unhealthy snacking and drinking behavior, mechanisms explaining these associations remain to be explored. The present study will therefore examine whether the associations between SR and unhealthy snack and/or sugar-sweetened beverage (SSB) intake are mediated by external and/or emotional eating and if this mediation is moderated by availability at home or at school. METHODS: Cross-sectional data on snacking, availability of snacks at home and at school, SR (BAS drive scale) and external and emotional eating (Dutch eating behavior questionnaire) of Flemish adolescents (n = 1104, mean age = 14.7 ± 0.8 years; 51 % boys; 18.0% overweight) in 20 schools spread across Flanders were collected. Moderated mediation analyses were conducted using generalized structural equation modeling in three steps: (1) direct association between SR and unhealthy snack or SSB intake, (2) mediation of either external or emotional eating and (3) interaction of home or school availability and emotional or external eating. RESULTS: Partial mediation of external eating (a*b = 0.69, p < 0.05) and of emotional eating (a*b = 0.92, p < 0.01) in the relation between SR and intake of unhealthy snacks was found (step 2). The relation between SR and SSB intake was not mediated by external or emotional eating (step 2). No moderation effects of home or school availability were found (step 3). CONCLUSION: Our findings indicate that the association between SR and the consumption of unhealthy snacks is partially explained by external and emotional eating in a population-based sample of adolescents irrespective of the home or school availability of these foods.

RESUMO

PURPOSE: High intake of palatable foods, such as energy-dense snacks and sugar-sweetened beverages (SSBs), is common among adolescents. An individual's sensitivity to reward (SR) may influence these intakes. The main objective of this study was to investigate the association between SR and both snack and SSB intake among adolescents. METHODS: A representative cross-sectional survey was conducted among 1104 14- to 16-year-olds (mean age = 14.7 ± 0.8 years; 50.9 % boys; 18.0 % overweight) in Flanders. Daily intakes were measured by a food frequency questionnaire. SR was assessed using the behavioral activation system (BAS) scales. Multilevel regression analyses (two level: adolescent school) were conducted using STATA version 13. RESULTS: BAS drive was positively associated with daily intakes of SSBs (13.79 %, p < 0.01), unhealthy snacks (5.42 %, p < 0.001), and energy and nutrients derived from SSBs (p < 0.001) and snacks (p < 0.01). BAS reward responsiveness (RR) was only positively associated with intake of unhealthy snacks (3.85 %, p < 0.05), healthy snacks (6.41 %, p < 0.05), and fat (4.05 %, p < 0.01) and Na (3.89 %, p < 0.05) from snacks. Interaction effects of gender and BAS RR (p < 0.05) were found. Significant positive associations between BAS RR and daily intakes of energy from snacks (6.48 %, p < 0.01) and fat from snacks (7.22 %, p < 0.001) were found only for girls. CONCLUSION: SR was associated with snack and SSB consumption in adolescents, especially in girls. These findings suggest that SR should be taken into account when designing interventions to improve the snack and SSB intake of adolescents.

RESUMO

UNLABELLED: Online communication is associated with offline romantic and sexual activity among college students. Yet, it is unknown whether online communication is associated with the initiation of romantic and sexual activity among adolescents. This two-wave panel study investigated whether chatting, visiting dating websites, and visiting erotic contact websites predicted adolescents' initiation of romantic and sexual activity. We analyzed two-wave panel data from 1163 Belgian adolescents who participated in the MORES Study. We investigated the longitudinal impact of online communication on the initiation of romantic relationships and sexual intercourse using logistic regression analyses. The odds ratios of initiating a romantic relationship among romantically inexperienced adolescents who frequently used chat rooms, dating websites, or erotic contact websites were two to three times larger than those of non-users. Among sexually inexperienced adolescents who frequently used chat rooms, dating websites, or erotic contact websites, the odds ratios of initiating sexual intercourse were two to five times larger than that among non-users, even after a number of other relevant factors were introduced. CONCLUSION: This is the first study to demonstrate that online communication predicts the initiation of offline sexual and romantic activity as early as adolescence.

RESUMO

Despite increasing evidence that specific types of Facebook use (i.e., active private, active public, and passive Facebook use) are differently related to adolescents' well-being, little is known how these types function over the course of adolescence and whether gender and Facebook motives may predict the initial level and changes in these types over time. To address these gaps, Flemish adolescents (ages 12-19) were questioned at three different time points, with six months in between (NTime1 = 1866). Latent growth curve models revealed that active private Facebook use increased over the course of adolescence, whereas public Facebook use decreased. Passive Facebook use, however, remained stable. In addition, gender and Facebook motives were related to initial levels of specific types of Facebook use, and predictive of dynamic change in specific types of Facebook use over time. The discussion focuses on the understanding and implications of these findings.
