NCT06207526

Brief Summary

The project aims to investigate the feasibility and acceptability of a blended face-to-face and smartphone intervention for distressing thoughts and experiences in people with schizophrenia spectrum disorders. A secondary aim is to assess the outcomes of the intervention at baseline (T0) and post-intervention (T1) (single-arm feasibility design). The study design is primarily based on Bell et al.'s (2018, 2020) blended face-to-face and smartphone intervention for hallucinations. The participants receive four face-to-face therapy sessions, using a smartphone between sessions employing elements of Ecological Momentary Assessment (EMA) and Intervention (EMI).

Outcome Measures

Primary Outcomes (3)

  • Feasibility and acceptability of the intervention

    Feasibility will be indexed by completion rates of the EMA questionnaires (minimum threshold of \>33% of completed EMA questionnaires), by whether participants use the application between sessions (\>80% of clients) and whether the target level of ecological momentary assessment data for analysis is recorded (\>80% of clients).

    Post-Intervention (after completion of 4 face-to-face psychotherapy sessions; 4-6 weeks from baseline)

  • Acceptability of the intervention

    Acceptability will be assessed by using the Client Satisfaction Questionnaire (Attkisson \& Zwick, 1982) and a series of open-ended questions about elements of the intervention, in addition to the rate of intervention completion (\>80% complete all sessions).

    Post-intervention (after completion of 4 face-to-face psychotherapy sessions; 4-6 weeks from baseline)

  • Side effects

    Negative effects will be recorded by using the Negative Incidents and Effects Questionnaire (Rozental et al., 2019).

    Post-intervention (after completion of 4 face-to-face psychotherapy sessions; 4-6 weeks from baseline)

Secondary Outcomes (7)

  • Objective intensity of delusions

    At baseline and post-intervention (after completion of 4 face-to-face psychotherapy sessions; 4-6 weeks from baseline)

  • Subjective intensity of delusions

    At baseline and post-intervention (after completion of 4 face-to-face psychotherapy sessions; 4-6 weeks from baseline)

  • Psychological distress

    At baseline and post-intervention (after completion of 4 face-to-face psychotherapy sessions; 4-6 weeks from baseline)

  • Stress, anxiety and depression

    At baseline and post-intervention (after completion of 4 face-to-face psychotherapy sessions; 4-6 weeks from baseline)

  • self-assessed recovery

    Post-intervention (after completion of 4 face-to-face psychotherapy sessions; 4-6 weeks from baseline)

  • +2 more secondary outcomes

Study Arms (1)

Blended face-to-face and smartphone intervention for delusional thoughts and experiences

EXPERIMENTAL

The blended face-to-face and smartphone intervention is implemented as a four-session intervention that is primarily based on an intervention from Bell et al. (2018/2020) which focused on hallucinations and is now being tailored to delusions. The intervention itself builds on the "Coping Strategy Enhancement" - program by Tarrier and colleagues (CSE; (Tarrier et al., 1990) by systematically build upon already applied coping strategies and therefore improve coping with psychotic symptoms. Participants receive four therapy sessions in person, while the app is used to collect data between sessions to be used in therapy and to record and train coping strategies between sessions. All participants are allowed to continue parallel implemented standard scheduled treatment.

Behavioral: Blended face-to-face and smartphone intervention

Interventions

The intervention comprises two phases: an initial stage involves baseline assessment, in-depth app training, psychoeducation, and EMA monitoring for functional analysis. The subsequent phase focuses on identifying and implementing individual coping strategies, forming the basis for daily personalized EMI reminders. Over six days, participants receive ten daily surveys to gauge fluctuations in paranoia and delusional ideation. EMA-derived feedback, considering antecedents and coping responses, shapes a personalized EMI. Four sessions with a psychologist involve discussing app feedback, emphasizing functional analysis, coding coping strategies into the app, assessing utility, and adapting as needed. Post-session two, five coping reminders and an eight-item evening survey are sent daily for two blocks of ten days to monitor delusional ideations and coping strategy effectiveness.
