| Peters Delusion Inventors (PDI-21) - A 21-item scale that assesses the degree of expression of psychotic beliefs. Three dimensions of delusional beliefs are investigated: the degrees of preoccupation, of conviction, and of related anxiety. This scale has notably been used to investigate the benefits of cognitive and behavioural therapies of psychoses (Garety et al., 1997 and Kuipers et al., 1997 and 1998). Measured at baseline, Months 3 (post Michael's Game Treatment) and six months later | — |

| All measured at baseline, Months 3 (post Michael's Game Treatment) and six months later 1. The BPRS (Brief psychiatry rating scale) (Overall et al. 1961) An 18-item scale that measures the severity of the symptoms in functional psychoses. Comes in the form of a semi-structured interview. 2. The BCIS (Beck Cognitive Insight Scale (Beck et al. 2004) A 15-item scale that assesses self-reflectiveness (insight and desire to recognize its fallibility) and self-certainty (certainty regarding patients? beliefs and judgement) regarding the interpretation patients have for their experience.This self-report questionnaire enables the research units to access the patients? ability to evaluate their abnormal experiences and their erroneous inferences. 3. PDI 21 Peters and al. Delusions Inventory Peters et al. (1999) A 21-item scale that assesses the degree of expression of psychotic beliefs. Three dimensions of delusional beliefs are investigated: the degrees of preoccupation, of conviction, and of related anxiety. This scale has notably been used to investigate the benefits of cognitive and behavioural therapies of psychoses (Garety et al., 1997 and Kuipers et al., 1997 and 1998) 4. The GAF [Global Assessment of Functioning] (DSM-IV) A scale that allows for an evaluation of the level of global functioning (psychological, social, and professional) of a person by means of a unique score. It can be divided into ten levels of functioning. The description of each level has two components: the first one corresponds to the severity of the symptoms, and the second one to functioning. This scale has good psychometric qualities and is a tool frequently used in clinical routine. 5. The SOFAS [Social and Occupational Functioning Assessment Scale] (DSM-IV) In contrast with the GAF, the SOFAS focuses on the individual's level of social and occupational functioning while excluding severity of symptoms. | — |
