The aim was to investigate the knowledge and the attitude regarding recovery among practitioners working in the Swedish mental health system, Personligt Ombud (PO), Supported Housing Team (SHT) and Psychiatric Out Patient Service (POPS), to determine whether and how knowledge and attitude regarding recovery differ between the three services. A web-based questionnaire based on the Recovery Knowledge Inventory was sent to the participants. Participant selection ensured that different parts of Sweden were represented. A multiple linear regression was used to examine the result under control of Sex, Age, Educational Level, Further Education, Relevant Work Experience and Training in Recovery. The result of the regression showed that POs had higher scores than both SHT and POPS on the subscales, even under control of other variables. The SHT differed significantly from POs on two of the subscales and POPS differed significantly from POs on all subscales. Personnel with university education, more work experience or specific training in recovery also had a higher mean score. Swedish practitioners need to learn more about certain aspects of the recovery process. The differences between the services may possibly be due to the services' organization, assignment and role. Other important aspects were the level of education and having specific training in recovery; the combination of these elements could facilitate the development of a recovery-oriented mental health system.
