- Target number of participants150
- InterventionsParticipants in the daily-life ACT group will receive five standard group ACT sessions, embedded in an six-week period during which they are trained to apply the skills learned during the sessions to their daily lives with help of a PsyMate®. Participants in the standard ACT group will only receive the five ACT sessions. All three groups will receive TAU from the clinic or institution they are admitted to.
- Primary outcomeThe study’s main parameters are (sub-)clinical symptoms and general and social functioning, as measured with questionnaires and interviews.
- Secondary outcomeSecondary parameters are stress-reactivity, momentary cortisol fluctuations, reward-experience, and overall positive affect, as measured with the experience sampling method (ESM).

- Brief summaryRationale: Despite attempts to prevent or delay transition to psychosis with antipsychotic medication or traditional cognitive behavioural therapy (CBT), individuals with an at-risk mental state (ARMS) present with poor functioning and high levels of general psychopathology, even in the absence of transition. Acceptance and commitment therapy (ACT; a next generation CBT) is aimed at changing the relationship between the individual and his complaints through detachment and acceptance. Clinical improvement is achieved as a result of reduced distress and impairment, rather than the other way around. As such, ACT could be a particularly interesting candidate treatment for this vulnerable group. A promising new intervention method includes integration of the treatment in the daily-lives of the individuals using mobile technology, which could substantially increase the treatment effects.

Objective: The current project aims to investigate the efficacy of a new form of treatment that integrates ACT in the daily-lives of ARMS individuals using a small digital device (PsyMate®). We hypothesise the ARMS individuals who receive the experimental treatment to improve on measures of clinical and general functioning, stress-reactivity, and reward-experience compared to individuals who receive a standard ACT treatment and those who receive a control treatment.

Study design: A multi-centre randomised controlled trial (RCT) with three arms i) daily-life ACT, ii) standard ACT, and iii) treatment as usual (TAU), with measurements at pre-intervention, post-intervention, and follow-up at six, 12, and 24 months post-intervention.

Study population: ARMS individuals who seek help at a clinic or institution for sub-clinical psychotic complaints.

Intervention: Participants in the daily-life ACT group will receive five standard group ACT sessions, embedded in an six-week period during which they are trained to apply the skills learned during the sessions to their daily lives with help of a PsyMate®. Participants in the standard ACT group will only receive the five ACT sessions. All three groups will receive TAU from the clinic or institution they are admitted to.

Main study parameters/endpoints: The study’s main parameters are (sub-)clinical symptoms and general and social functioning, as measured by questionnaires and interviews, and stress-reactivity, momentary cortisol fluctuations, reward-experience, and overall positive affect, measured with the experience sampling method (ESM).
