SUMMARY
Objective: The aim of this cross-sectional study was to examine the relationship between sexting, risky sexual behaviour, and features of borderline personality disorder.Subject and methods: The study, conducted in Bosnia and Herzegovina and Croatia, involved 265 people (70 males and 195 females) ranging in age from 17 to 25 years, with an average age of M = 23.57 (SD = 3.2). Participant completed The Intimate Images Diffusion Scale among Adolescents, the Sexual Risk Behaviour Scale, and a Borderline Symptom Questionnaire (BSL-23).Results: The results of this study show that individuals who reported participating in sexting scored higher on the BSL-23. Those who participate in sexting are less likely to use protection during sexual activity, are more likely to change sexual partners, and they are more likely to engage in sexual activity under the influence of alcohol and narcotics. The features of borderline personality disorder, the number of sexual partners in the last 6 months, use of condoms, and sexual activity under the influence of alcohol have been shown to be significant predictors of participation in sexting.Conclusion: The results obtained indicate that mobile phones and internet make it easier the development of problematic patterns of behaviour, and for experiencing negative psychological consequences.
