Clinical Trial Summary

This study aims to investigate the effects of the Switch intervention on motivation and associated processes and explore the dynamics between the processes.

A single case approach is followed, with a pre-post and follow-up assessment design, and continuous ambulatory assessments (experience sampling method (ESM) and step count).


Description:

Motivational negative symptoms hinder quality of life and daily functioning of individuals with schizophrenia spectrum, bipolar and major depressive disorders.

A recently developed intervention, Switch, has shown promising effects on negative symptoms and functional outcomes. Switch is based on a model that identifies various cognitive, behavioural and emotional processes related to motivation and goal-directed behaviours: pleasure anticipation, value-effort-probability computation, (dys)functional attitudes (e.g., discouraging thoughts, self-efficacy), planning, initiation, in-the-moment enjoyment, reminiscence. The intervention combines a person-centred and recovery approach with cognitive, behavioural and 3rd wave techniques to tackle the obstacles related to motivation and goal-directed behaviours (i.e., targetting the various cognitive, behavioural and emotional processes listed above). Thus, an important part of the intervention focuses on the person's strengths, needs, goals and values. Furthermore, various strategies (e.g., cognitive defusion, pleasure anticipation, problem solving, reminiscence) are used to encourage engagement in meaningful personal goals and values.

The Switch intervention is provided either in individual (one-hour sessions), or in a group setting (two-hour sessions), twice a week for around two months.

There are three types of evaluation: traditional assessment scales of motivational deficits, apathy, quality of life and daily functioning (pre, post and follow-up at 3 months); ambulatory assessment including ESM (i.e., daily questionnaires); actigraphy (step count).

The aims of this study is to evaluate the efficacy of Switch in two different settings (i.e., individual sessions and a group programme) on motivation/apathy and functional outcomes/quality of life. Furthermore, we wish to explore the effects of Switch on process related to motivation and goal-directed behaviours (e.g., pleasure anticipation, reminiscence, defeatist beliefs, activities' meaningfulness) and on activity (i.e., step count). Finally, we wish to evaluate the dynamics between the different cognitive, behavioural and emotional processes related to motivation and goal-directed behaviours.

Study Design


Intervention

Behavioral:
Switch - Individual sessions
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 - Group programme
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).

Type Measure Description Time frame Safety issue
Primary 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).

Primary 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). Baseline

Primary 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. Baseline (month 0)
