Exposure to more types of Adverse Childhood Experiences (ACEs) has been associated with a greater likelihood of general and sexual offending behaviors. However, few studies exist that consider both the impact of varied ACE exposures and community correlates on pathways to offending behaviors in adolescents who have engaged in sexually abusive behaviors. The current study examined these pathways using data collected from archival records of male adolescents (N= 285) who had received treatment for sexually abusive behavior at a youth facility. Structural equation modeling revealed a three-factor model for ACEs, which included: nonsexual abuse and neglect; household dysfunction; and sexual abuse and more passive indicators of sexual boundary problems in the home of origin. Direction and significance of paths between ACEs and the onset, persistence, and nature of maladaptive behaviors differed. Household dysfunction was related to an earlier onset and more persistent nonsexual delinquent offending and contact sexual offending. Conversely, sexual abuse and exposure to sexual boundary problems were associated with an earlier onset of sexually abusive behavior as well as indicators of adolescent-onset, less persistent, and nonviolent delinquency. Nonsexual abuse and neglect were uniquely associated with contact sexual offending. Thus, these findings suggest variations in ACE exposures differentially influence the development, severity, and continuance of nonsexual delinquent and sexually abusive behaviors among these youths. Socioecological variables associated with participants’ counties of origin, including social and economic environment and percentage of rurality, were not retained as covariates due to producing a poor model fit for the data. Additional study with regard to the role of community characteristics on delinquent and sexual offending behaviors is warranted.

Denna studie syftar till att undersöka sambandet mellan kriminalitet, viktimisering och exponering för kriminogena situationer. Självrapporterad data samlades in vid tre tillfällen från 525 Malmöungdomar, varav 320 uppfyllde studiens inkluderingskriterier. Resultaten visar att mycket tid spenderad oövervakad, mycket tid ägnad åt ostrukturerade aktiviteter, mycket tid i sällskap med vänner samt alkoholkonsumtion samvarierar med brottslighet och viktimisering i varierande utsträckning. Sambanden varierar dock i förhållande till de båda utfallsvariablerna och deltagarnas ålder. Livsstils-rutinaktivitetsteorin kan förklara resultaten men behöver i framtiden ta större hänsyn till ålder. Studiens två slutsatser är att (1) brottslighet och viktimisering bör betraktas som två olika men klart relaterade företeelser i förhållande till exponering för kriminogena situationer och att (2) ålder måste tas i beaktande i forskning om exponering för kriminogena situationer eftersom sambanden mellan exponering och de båda utfallsvariablerna varierar från tidiga till sena tonår. / This study aims to examine offending and victimization in relation to situational criminogenic exposure. Self-reported data was collected at three occasions from a sample of 525 adolescents in Malmö, of which 320 fulfilled the study’s inclusion criteria. The results show that spending a lot of time unsupervised, pursuing unstructured activities, spending a lot of time with peers, and alcohol use, are associated with offending and victimization to various extent. However, the associations vary according to outcome and in relation to the participants’ age. Lifestyle-Routine Activities Theory may explain the findings, but needs to consider age as an important factor in the future. The two conclusions from this study are that (1) offending and victimization should be treated as two different, yet related concepts in relation to situational criminogenic exposure, and that (2) it is important to add an age dimension to the study of situational criminogenic exposure because the associations between the exposure variables and the outcome variables vary from early to late adolescence.

Research in life-course criminology has been studying turning points away from criminality. There is although a limited amount of research that has been focusing on parenthood and especially on fatherhood as a potential turning point. The available studies show mixed results in this topic and the findings suggest that there are factors that can both form and restrict fatherhood as a potential turning point towards desistance. The aim for the present thesis is therefore to get a better understanding of fatherhood as a potential turning point from persistent offending and to examine the role and meaning of fatherhood in the criminal careers of Swedish former criminals. Qualitative method in the form of retrospective semi- structured interviews has been used to collect data and five former offenders that became fathers during their criminal career participated in the study. The data have been analysed with systematic text condensation and the results indicate that the men did not desist after becoming fathers. They did however have both intended and unintended breaks from criminality when their child was born, but the criminal lifestyle was their first choice and their children were put on the second place. Relationships to friends and in some cases to the mother of the child was a restricting factor for fatherhood to become a turning point. Another factor that restricted fatherhood from being a potential turning point was human agency. The men concluded that an offending father can not receive help from society if there is no will for the father to desist.

Persons with traumatic brain injuries (TBI) who have engaged in problematic or illegal sexual behavior present with complex assessment and intervention needs yet remain understudied within the empirical literature. In the current exploratory analysis, important differences in adaptive and clinical functioning, adverse childhood experiences, and criminal offense history are examined in 25 persons with previous brain injury, 118 persons with intellectual disability but no known TBI, and 103 persons with no history of brain injury or intellectual disability, all of whom have engaged in problematic sexual behavior and who were residing in secure forensic inpatient care. Group differences were examined using comparisons of means and chi-squares. Results highlight important differences in education and employment experiences, diagnostic presentation, exposure to childhood maltreatment, and justice system involvement and characteristics of their sexual offense victims. Associations with prior literature and future research directions are discussed.

The thesis was aimed to investigate the structure of a criminal network and how the EncroChat-communication- and co-offending-structure differs. To study this, a network analytical method was applied that resulted in four networks: co-offending according to the verdict, co-offending according to the prosecution, Encrochat-communication and a network where these three networks were merged. The results showed that the cooffending networks obtained a more compact composition than the EncroChatcommunication network. All networks had a dense core containing the most central actors, although some exceptions existed in the co-offending networks. The results of the network analysis indicated that the actors who committed the most crimes also communicated the most. The results also showed a partly different composition of other prominent actors in the network analysis than what the prosecutor presented. Therefore, network analysis can be used as an extra dimension in law enforcement work due to its function in identifying structures.
