This research aimed to describe the inner dialogues of psychiatrists in the context of the Need-Adapted treatment of psychosis. It strived to show that the experiences of professionals can have an impact on the treatments offered. In addition, the research aimed to clarify how the phenomenon of professionals' inner dialogues may be studied.The data for the three studies of the research consisted of eight videotaped and transcribed stimulated recall interviews with psychiatrists, who recalled their inner dialogues, assisted by videos from co-research interviews. The dialogues took place in multi-agent discussions with patients, with the family members of patients, and with other professionals. The first study provided an overall picture of the research material, with a focus on psychiatrists' inner dialogues concerning their workmates. The second study focused on how the psychiatrists viewed their agency. The third study dealt with the impact of psychosis on the treatment, the psychiatrists, and other professionals. The first two studies used adaptations of dialogical-narrative analysis, while the third study used an adaptation of qualitative content analysis.From the perspective of real-world clinical practice the studies suggested the following: (i) since psychiatrists interact with the clients and with other professionals, they respond as embodied individual human beings with possibly strong emotions; this suggests that the experiences and inner dialogues of the participants may be interdependent; (ii) clinician-clinician relationships can be of crucial importance in the treatment; (iii) especially in the inpatient setting, institutional forces can have an enormous impact on psychiatrists' agency by reducing professional creativity, and occasionally, by leading to a kind of agentless situation; (iv) psychiatrists seem to be more or less aware of the many harmful effects of (in particular) inpatient treatment; (v) the interview methods used in the research increased professionals' reflective opportunities, indicating that such interviews could be helpful in the dilemmas professionals encounter in practice. Tämän tutkimuksen tavoite oli kuvata psykiatrien sisäistä keskustelua psykoosien tarpeenmukaisen hoitomallin kontekstissa. Se pyrki osoittamaan, että ammattilaisten kokemuksilla voi olla vaikutusta tarjottuun hoitoon, ja selvittä-mään, miten ammattilaisten sisäistä keskustelua voidaan tutkia. Kolmen osatutkimuksen aineisto koostui kahdeksasta videolle tallennetusta ja transkriptoidusta stimulated recall -haastattelusta, joissa psykiatrit yhteisen tutkimisen haastattelun kuvanauhan avulla palauttivat mieleensä sisäistä keskusteluaan. Yhteisen tutkimisen haastattelu oli ryhmäkeskustelu, jossa oli lääkärien ohella läsnä potilas, hänen perheenjäseniään sekä muita ammattilaisia. Ensimmäisessä osatutkimuksessa kuvattiin tutkimusaineistoa kokonaisuudessaan ja keskityttiin psykiatrien työtovereita koskevaan sisäiseen keskusteluun. Toisessa osatutkimuksessa paneuduttiin psykiatrien kokemukseen toimijuudestaan....
