Outcome Measures

Primary Outcomes (12)

  • Brief Negative Symptom Scale (BNSS)

    There are 13 items that are scored from 0 to 6 (0 = no impairment; 1 = very slight; 2 = mild; 3 = moderate; 4 = moderately severe; 5 = marked; 6 = severe). The Expressive deficit factor includes the following subscales: Blunted affect (facial expression, vocal expression, expressive gestures) and Alogia (quantity of speech, spontaneous elaboration).Each item is scored from 0 to 6 (0 = no impairment; 1 = very slight; 2 = mild; 3 = moderate; 4 = moderately severe; 5 = marked; 6 = severe).

    6 months (follow-up)

  • Lille Apathy Rating Scale (patient version) (LARS-p)

    The LARS is a semi-structured interview designed to evaluate the different dimensions (cognitive, emotional and behavioural) of apathy in schizophrenia, through the following subscales: Everyday productivity, Interests, Taking initiatives, Novelty seeking, Voluntary actions, Emotional responses, Concern, Social life and Self-awareness. The total score ranges from -36 to 36 (\[-36; -22\] = absence of apathy; \[-21; -17\] = tendency towards apathy; \[-16; -10\] = moderate apathy; \[-9; 36\] = severe apathy).

    The LARS is a semi-structured interview designed to evaluate the different dimensions (cognitive, emotional and behavioural) of apathy in schizophrenia, through the following subscales: Everyday productivity, Interests, Taking initiatives, Novelty seeking, Voluntary actions, Emotional responses, Concern, Social life and Self-awareness. The total score ranges from -36 to 36 (\[-36; -22\] = absence of apathy; \[-21; -17\] = tendency towards apathy; \[-16; -10\] = moderate apathy; \[-9; 36\] = severe apathy).

    6 months (follow-up)

  • Schizophrenia - Quality of Life questionnaire

    The S-QoL is a 41-item questionnaire that evaluates life satisfaction regarding psychological wellbeing, self-esteem, family relationships, relationships with friends, resilience, physical wellbeing, autonomy and sentimental life. Items are rated on a 5-point Likert scale (1 = much less satisfied than expected; 2 = less satisfied; 3 = slightly less satisfied; 4 = as satisfied; 5 = more satisfied). The total score ranges from 0 to 100, higher scores indicating better subjective quality of life.

  • Functional Remission of General Schizophrenia (FROGS)

    The FROGS is a measure of daily life outcomes, which evaluates level of functioning in 5 different domains: Daily life, Activities, Relationships, Quality of adaptation, and Health and treatment. The total score ranges from 19 to 95. The threshold score for remission is 61.

Interventions

Participants follow the Switch intervention through individual sessions (1 hour, twice a week, for around 2 months). Participants are provided with a folder which presents the rational for each strategy. Take-home assignments are given and stored in the same folder. Participants are also given small cards (that can fit in their wallet) containing the key elements of each strategy. The intervention manual can be obtained from the main investigator (in French).

Switch - i

Participants follow the Switch group programme (2 hours, twice a week, for around 2 months). During the group sessions, a powerpoint presentation and different media are used to present the different parts of the motivation model. Participants learn the different strategies (e.g., cognitive defusion, pleasure anticipation, problem solving) through individual and group exercises. Participants are provided with a folder which presents the rational for each strategy. Take-home assignments are given and stored in the same folder. Participants are also given small cards (that can fit in their wallet) containing the key elements of each strategy. The intervention manual and the presentation material can be obtained from the main investigator (in French).
