- Registration Number
- NCT03625206
- Lead Sponsor
- Institute of Psychiatry, London
- Brief Summary
Adolescents who have experienced adversity (childhood maltreatment and other forms of broader victimisation experiences) will be randomly allocated to receive a 5-session cognitive bias modification training (with attention and interpretation bias modification modules) or a control condition. Outcome measures include measures of cognitive biases and symptoms of psychopathology; in addition, in a subset of adolescents, brain activity data will be acquired. All adolescents will complete a feedback form, upon which acceptability of the intervention will be assessed.
- Detailed Description
Up to 80 adolescents aged 12-18 years who have experienced adversity (childhood maltreatment and other forms of broader victimisation experiences) from India and Nepal will be randomly allocated to receive a 5-session cognitive bias modification training (with attention and interpretation bias modification modules) or a control condition over a 2-week period.
Pre and post-assessment measures include measures of attention and interpretation biases and symptoms of internalising and externalising psychopathology. In addition, in a subset of adolescents, brain activity data acquired using EEG will be acquired either during resting or viewing emotional face stimuli. Data from these measures will be used to generate effect sizes of changes for each group as well as being used in a limited number of significance-testing analysis. All adolescents will complete a feedback form, upon which acceptability of the intervention will be assessed.

- Primary Outcome Measures
Name Time Method Attention biases for threatening stimuli Immediately after the intervention (post-intervention) The investigators will use an experimental measure (a visual search task) that uses reaction times (RTs) to different experimental conditions to index the degree to which attention is captured by a threatening over a non-threatening stimulus.
Interpretation biases for threatening explanations Immediately after the intervention (post-intervention) The investigators will use an experimental measure (an ambiguous scenarios task) that uses ratings to different experimental trials to index the degree to which individuals endorse threatening over benign interpretations
- Secondary Outcome Measures
Name Time Method Symptoms of emotional, behavioural and social problems Immediately after the intervention (post-intervention) 5 subscales of the Strength and Difficulties questionnaire
Acceptability of intervention Immediately after the intervention (post-intervention) The investigators have developed a 19-item self-report feedback, comprising quantitative ratings and qualitative responses. Across eleven items, young people rate on a 4-point Likert scale whether they found the training useful, satisfying, engaging, realistic, whether it impacted anxiety, mood, coping strategies, and other difficulties , and whether they would feel motivated to complete the sessions, including without a researcher present. Higher scores reflect greater endorsement. Each of these items will be reported separately rather than used to create composite scores. There are also 8 open ended questions for young people to leave their feedback on aspects they found helpful, unhelpful, liked, disliked, improvements they would want, and other general comments.
