Research program I: Deliberate self-harm, impulse control, emotion regulation and violence: Intervention and epidemiological studies
Deliberate self-harm (DSH) refers to both non-suicidal self-injury (such as cutting or burning one’s skin to manage emotional distress) as well as intentional self-poisoning or self-injury regardless of intent. DSH is a serious global health problem and is common also in Sweden; recent Swedish studies indicate that the frequency of those who had self-harmed >5 times is close to 8%. Common comorbid conditions are neuropsychiatric disorders, eating disorders, substance use, depression and anxiety.
Anger, aggression and impulsivity are psychological traits associated with several psychiatric diagnoses, e.g. ADHD, conduct disorder, and antisocial personality disorder. Such traits are also associated with both attempted and completed suicide as well as violent behaviours. Previous studies have identified higher prevalence of self-harm in prison populations; our recent study (see below) have now pointed to increased levels of violent behaviours among those who have received care for self-harm within the health care system. Theoretical and empirical literature emphasizes the central role of emotion regulation in the development and maintenance of self-injury; thus, several of our projects involve aspects of emotion regulation.
This project combines epidemiological and intervention studies. The register-based studies will hopefully help us understand more of the development of these conditions, e.g. the characteristics of those seeking care for self-harm, short and long term interactions with the health care system, possible risks associated with certain pharmacological interventions, and what other conditions are associated with self-harm.
We have completed one intervention study for adults with self-harm; ERGT or Emotion Regulation Group Therapy. For self-harming youth, few interventions have yielded significant and consistent positive outcomes. We are now testing an early intervention targeting 13-17 year olds and their caregivers; Emotion Regulation Individual Therapy for Adolescents (ERITA).

Research program II: Empathy disorders in children and youth
In this program, we investigate psychopathic traits with a focus on “callous-unemotional” (CU)-traits in different youth populations. CU-traits reflect deviant personality traits and behaviors including lack of empathy and guilt, unconcern about own performance and shallow affect. CU-traits could constitute a risk factor for antisocial behaviour, poor treatment adherence and distinct emotional difficulties. The latest edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), includes the specifier “with Limited Prosocial Emotions” to encourage assessment of CU-traits in children and youth with deviant behaviors. In register-based studies, we investigate prevalence and correlates of CU-traits, including associations with trauma exposure – in large community samples of youth. This program also includes an ongoing clinical study where CU-traits are investigated in relation to empathy, fear responding, anxiety and attention in youth with different psychiatric disorders.

Research program III: Interventions for problem gambling
Problem gambling (as opposed to gaming, where money is not involved) is characterized by the failure to control the amount of gambling despite negative financial, social and personal consequences. Approximately 2% of the Swedish population is estimated to be either problem gamblers or moderate risk gamblers. However, in association to each problem gambler there may be a higher number of significant others who are affected. These two studies both involve interventions that involve significant others. The “Spelfrihet tillsammans”-project (“Gambling free together”) compares internet mediated cognitive behavioural therapy with a joint intervention for couples (involving either a spouse, an adult relative or someone else who is close to the gamber). The “Anhörigstudien” (“The significant other-project”) focuses solely on those close to the gambler, comparing an intervention directed to the significant other to just providing brief information about gambling. The outcome in this project is whether the gambler will be more motivated to participate in treatment.
