Studies in pathways to care - duration of untreated psychosis and its determining factors in early psychosis
(Doctoral thesis; Doktorgradsavhandling, 2018-11-23)Mange pasienter med en førstegangspsykose får behandling sent i forløpet og har en lang varighet av ubehandlet psykose (VUP). Forsinket behandling kan skyldes både indre (lidelse og pasient relaterte) og ytre (tjeneste og systemrelaterte) faktorer. Til tross for at nyere forskning har dokumentert at en stor del av forsinkelsen skjer mens pasienten mottar behandling i spesialisthelsetjenesten, så er ... -
Sex differences in pain, fear of pain and placebo analgesia
(Doctoral thesis; Doktorgradsavhandling, 2018-11-13)The hypothesis that males are more responsive to placebo treatment than females was tested experimentally in this thesis.
