Research

My research group Turku Psychosis and Substance Use (TuPSU) focuses on epidemiology of substance use and psychosis. 

Research questions under study include e.g.: 

Does adolescent substance use associate with increased risk for subsequent psychotic disorders or other severe outcomes in adulthood?
What is the prognosis of incident substance-induced psychosis and is it different from other types of first-episode psychosis?




We aim to utilize national register-based datasets, which enable to study substance-induced psychosis and co-occuring substance use among persons with psychotic disorders with minimal attrition, in these otherwise difficult-to-reach populations.  

The ongoing reserarch projects include: 


  • Prognosis of adolescent substance use in the Northern Finland Birth Cohort 1986. A general population study with ongoing register-linkage follow-up. (PI)
  • Substance-induced psychosis in Swedish national registeries (SIP-project). A register-linkage study of 7320 cases with substance-induced psychosis. In collaboration with A/Prof Heidi Taipale from the Karolinska Instute, Stockholm. Sweden. (PI)
  • Substance use in the Turku University Hospital Datalake. Extensive patient record -based dataset with over 34,000 persons with substance-use-related admission at the Turku University Hospital. (PI)
  • Substance use and dual diagnosis in the Finnish SUPER study including 10, 470 patients with psychotic disorders. In collaboration with Molecular Medicine Finland (FIMM), University of Helsinki and the Finnish Institute for Health and Welfare (THL). 
  • COVALC-consortium to study alcohol-related service use during the COVID19-pandemia. In collaboration with National Health Instutute (THL). 
  • Health Survey of Finnish Prisoners (WATTU IV). In collaboration with National Health Instutute (THL).
