AbstractThere are today only a few population-based studies in the world investigating the prevalence of and associated risk-factors with adolescents selling sex and so far no earlier populationbased study has been found investigating adolescents motives for selling sex. Further, to use sex in means of self-injury (SASI) is a behaviour that has been highlighted in Sweden the last years but it is a new field of research and a behaviour in need of conceptualizationThe aim of this thesis was to investigate the prevalence of, associated risk factors with, motives for and manifestations of adolescents selling sex and the use of sex as self-injury (SASI). For the thesis, two nationally representative cross-sectional population surveys with third year students at Swedish high schools were collected in 2009 (n = 3498, mean age 18.3 +/-0.6 years, response rate 60.4%) and in 2014 (n = 5839, mean age 18.0 +/-0.6 years, response rate 59.7%). Further, the motives and manifestations of SASI were investigated in an anonymous self-selected, open-ended questionnaire published on websites of nongovernmental organizations offering help and support to women and adolescents (n = 199, mean age 27.9 +/-9.3 years). Quantitative and qualitative methods were used for data analyses.In the 2009 population-based survey, 1.5% (n = 51) of the adolescents reported having sold sex on at least one occasion, but in 2014 the prevalence was slightly lower at 0.9% (n = 51). SASI was reported by 3.2% of girls (n = 100) and 0.8% of boys (n = 20). Both selling sex and SASI were associated with various adverse factors such as experience of sexual abuse, emotional and physical abuse, poor mental health and self-injury. Adolescents selling sex had sought help and support for different problems and worries to a greater extent compared to peers. Contact with healthcare for various psychiatric problems such as suicide attempts, depression and eating disorders was common for adolescents using SASI. Further analysis showed that adolescents selling sex are a heterogeneous group in regard to underlying motives for selling sex, which included emotional and material reasons as well as pleasure.Depending on their underlying motives, adolescents selling sex were found to differ in regard Abstract 2 to compensation received, age of the buyer, means of contact with the buyer, sexual orientation, experience of sexual abuse and the use of SAS...
