A Prospective Study of High-School Adolescent Sexting Behavior and Psychological Distress

Abstract

Relying on conceptualization of sexting as a deviant behavior, which appear to be related with mental health problems, we examined the relationship between sexting and psychological distress. A one-year longitudinal study was performed among 216 girls and 143 boys, aged from 15 to 17?years (M?=?16.32, SD = .64). Participants completed the Sexting Behavior Questionnaire and the Depression Anxiety and Stress Scale at both time points of the study. The results showed that the prevalence for receiving sexts between the two time points was around 30%, and for sending sexts around 60%. The prevalence rates of receiving and sending sexually explicit context were quite stable over time, though they varied significantly across gender. Participants usually had sexted with a current or (ex)partner or friends. The number of person with whom participants exchange sexts did not exceed five. Anxiety and stress symptoms were more prevalent among sexters who receive sexts at the baseline than follow-up study (p < .05). Stress has been found to be significant predictors of sending sext at the baseline study (p < .05), while depression of receiving and sending at the follow-up study (p < .001). This study confirms that sexting is common among youth, and appears to be associated with negative consequences.     

How to address the caveat of avoiding direct contact: Reducing prejudice towards gay and lesbian people in five Balkan countries

ABSTRACT

In the Balkans, contact with gays and lesbians is typically hostile or avoided. Drawing from probability samples of young people from five Balkan countries (N = 1046), we examined whether it is possible to transfer the effects of contact with other marginalized outgroups (largest ethnic minority in every country, Roma, the extremely poor and physically disabled) to acceptance of gays and lesbians (secondary outgroup), and whether this relationship could be explained by attitude generalization and increased intergroup trust. Path analyses supported the secondary transfer effect: it confirmed that, while controlling for direct contact, contact with other marginalized groups was related to more acceptance of a secondary group; this relationship was mediated by trust. This was found across all primary groups in the combined samples, while the effect varied for different groups in country samples. The results add to the value of intergroup contact as a mean of prejudice-reduction.     

Objective and epistemic gradability: Is the new angle on the Knobe effect empirically grounded?

According to the New Angle, any explanation of the Knobe effect must be gradable and asymmetric. It has been argued that only Hindriks’ approach meets both criteria. First, we argue that Holton’s hypothesis also meets the criteria. Second, we show that the authors are not justified in taking the criteria to be empirically justified. We have failed to replicate the asymmetry result in two experiments. Moreover, gradability can be objective or epistemic. We show that the New Angle presupposes objective gradability. In our experiments, the patterns of responses to questions about epistemic and objective gradability are the same, irrespective of whether the feature is objectively gradable (e.g., blameworthiness) or not (e.g., intentionality). Our results thus question the extent to which the New Angle is empirically grounded. Moreover, they raise doubt whether the answers to questions about epistemic and objective gradability can be taken at face value at all.

Differences between girls and boys in emerging language skills: Evidence from 10 language communities

The present study explored gender differences in emerging language skills in 13,783 European children from 10 non‐English language communities. It was based on a synthesis of published data assessed with adapted versions of the MacArthur‐Bates Communicative Development Inventories (CDIs) from age 0.08 to 2.06. The results showed that girls are slightly ahead of boys in early communicative gestures, in productive vocabulary, and in combining words. The difference increased with age. Boys were not found to be more variable than girls. Despite extensive variation in language skills between language communities, the difference between girls and boys remained. This suggests that the difference is caused by robust factors that do not change between language communities.     

Twin study of laboratory-induced aggression

The aim of this study was to explore genetic and environmental contributions to laboratory-induced aggressive behavior. On a sample of 478 adult twins (316 monozygotic), the Competitive Reaction Time Task was used for aggression induction. The results showed that the initial, basic level of aggression could be explained by both shared (45%) and nonshared environmental factors (55%), while only nonshared environmental factors (100%) had a significant influence on changes in aggression as provocation increased. Genetic factors had no influence on laboratory-induced aggression. The results highlight the importance of environmental factors in shaping situation-specific aggressive responses to provocation.     

Tryptophan Hydroxylase 1 Variant rs1800532 is Associated with Suicide Attempt in Serbian Psychiatric Patients but does not Moderate the Effect of Recent Stressful Life Events

Tryptophan hydroxylase 1 (TPH1) gene, coding for serotonin synthesizing enzyme, and recent stressful life events (SLEs) have been commonly associated with suicidal behavior. TPH1 has been also hypothesized to be involved in stress–response mechanisms. The aim of this study was to assess TPH1 variant rs1800532 and its possible interaction with recent SLEs as risk factors for suicide attempt (SA) in Serbian psychiatric patients, including 165 suicide attempters and 188 suicide nonattempters. rs1800532 and recent SLEs were independently associated with SA, while rs1800532 did not moderate the effect of recent SLEs on SA vulnerability among Serbian psychiatric patients.
