NCT06311084

Brief Summary

This study aims to investigate acceptability and feasibility of a new version of the Imaginator intervention, Imaginator 2.0, targeting self-harm behaviour in young people aged 12-25 under mental health services in the UK. Following an initial proof-of-concept study of Imaginator (Di Simplicio et al., 2020), a new version of the app that supports consolidation and practice of the techniques learnt in therapy was co-designed, and the protocol was adapted to be extended to younger adolescents. Imaginator 2.0 uses 'functional imagery training', training in individuals to develop and use functional (that is, helpful) mental images to support an alternative behaviour instead of self-harm. Mental imagery is the process of picturing something in the mind, and mental images have strong emotional and motivational characteristics. Functional Imagery Training (FIT) within Imaginator helps young people imagine adaptive behaviours as an alternative to self-harm when dealing with distressing emotions.

Outcome Measures

Primary Outcomes (4)

  • Number of Patients Lost to Attrition

    Percentage of eligible enrolled participants not completing outcome assessment

    1 year

  • Number of Patients Adhering to Treatment

    Percentage of participants completing number of sessions as per-protocol (five sessions) out of the 27 participants who started therapy.

    3 months

  • User Experience Questionnaire

    This is an acceptability measure of app use designed to assess perceptions of the app, with items rated on a 7-point Likert scale ranging from -3 to +3. A score of -3 reflects the poorest user experience, while a score of +3 represents the highest level of satisfaction. A score of 0 indicates a neutral experience. The questionnaire consists of 26 items divided across six subscales: Attractiveness (overall impression), Perspicuity (ease of understanding), Efficiency (task completion speed), Dependability (reliability), Stimulation (engagement and enjoyment), and Novelty (innovation and creativity). For each of the six dimensions, the mean score of the items that correspond to that dimension is calculated. Higher scores across these subscales reflect a better overall user experience, while lower scores highlight specific areas for improvement. For the purposes of this analysis, the average of all dimensions mean scores were calculated for each participant.

    3 months

  • Client Satisfaction Questionnaire (CSQ)

    This is an 8 item version (Attkisson \& Zwick, 1982) designed to provide a sensitive and comprehensive assessment of patient satisfaction with the therapy received. This was only administered post-treatment and sum scores were calculated for each participant. Each item is rated on a 4-point Likert scale, where responses range from 1 (very dissatisfied) to 4 (very satisfied). The individual scores from each item are summed to produce a total score for each participant, with a possible range of 8 (indicating low satisfaction) to 32 (indicating high satisfaction). Higher scores on the CSQ reflect greater overall satisfaction with the therapy received.
