Desire for information of people with severe mental illness

To assess (1) the desire of people with severe mental illness for information on their treatment and (2) whether the desire for information is associated with socio-demographic variables, diagnosis, illness duration, therapeutic relationship, needs and symptom severity.

588 outpatients with severe mental illness were recruited in six European countries (Germany, Denmark, Hungary, Italy, Switzerland, United Kingdom) during the "Clinical decision making and outcome in routine care of people with severe mental illness (CEDAR)" study (ISRCTN75841675). Desire for information was assessed by the Information subscale of the Clinical Decision Making Style Scale. Study participants with high desire for information were compared with those with moderate or low desire for information.

80 % of study participants (n = 462) wanted to receive information on all aspects of their treatment (management, prognosis, alternative options for care). Participants with a high desire for information had less severe symptoms (OR = 0.988, CI = 0.977-1.000) and a better self-rated therapeutic alliance (OR = 1.304, CI = 1.130-1.508) with their clinician.

Most, but not all, people with severe mental illness have a high desire for information. Desire for information is associated with variables, such as therapeutic relationship and symptom severity, which are amenable to change during treatment.
