The Positive And Negative Syndrome Scale is a scale hetero-evaluation of positive and negative symptomatology and general psychopathology in schizophrenia, consisting of 30 items, sides 1 to 7. The higher the score, the more severe the symptomatology. This scale provides scores on three syndromic dimensions: positive (7 items), negative (7 items) and positive (7 items), and general psychopathology (16 items) from a categorical and dimensional perspective.

Participants will be asked to list the goals they wish to achieve in 6 months or less, and the percentage of goals achieved will be assessed by the question "Were you able to achieve your goals? "to determine whether or not each personal goal was achieved. The expected response is yes vs. no for each personal goal. This methodology corresponds to the one classically used in CM-II studies (Fritzsche et al., 2016).

Participants will be asked to report on their perception of the effort associated with goal attainment as assessed by the question "Did achieving personal goals require you to make an effort? ". Responses will be on a 10-points Likert scale ranging from 1 ("no effort at all") to 10 ("a lot of effort").
