patients with schizophrenia who suffer from persistent delusions participated in cognitive defusion techniques on individual base through sex sessions twice weekly with homework assignments between sessions and skills demonstration by simulation and psychodrama.

patients with schizophrenia who suffer from persistent delusions participated in usual routine care in the hospital.

Defusing from your delusions helps to lessen their negative impact on your behaviour. So defusion is a vital step towards being able to act flexibly, in accordance with core values, instead of being dictated to by inflexible rules, reasons, judgments etc. There are numerous exercises in ACT Companion with a focus on identifying unhelpful thoughts which would benefit from defusion, or building defusion skills, most of which are found in the open up section of the app. Some of these are reading and writing exercises, and some are guided meditation audio recordings.

It is a seven-item self-reported scale developed to measure of psychological flexibility, with items targeted to several of the six key processes: defusion, acceptance, and committed action (example item: 'I worry about not being able to control my worries and feelings'.). Each item is followed by a seven-category response scale, started from never true (1), very seldom true (2), seldom true (3), sometimes true (4), frequently true (5), almost always true (6) to always true (7). Higher scores indicate greater psychological inflexibility (total score range: 7-49, calculated as the sum of the item responses). Previous research has reported a Cronbach's of 0.84.

It is designed to elicit one's level of cognitive fusion (example item: 'I find it easy to view my thoughts from a different perspective'.). Respondents rate each of 7 items on a 7- Likert scale ranging from 1 'Never true' to 7 'Always true'. Higher scores on the CFQ indicate greater cognitive fusion (total score range: 7-49, calculated as a sum of the responses). Studies demonstrate satisfactory reliability with a Cronbach's of 0.86.

Southampton Mindfulness Questionnaire is a 16-item scale that assesses the relationship one establishes with distressing thoughts and images (e.g., "I am able just to notice them without reacting"). Items are scored on a 7-point Likert scale, ranging from strongly disagree (0) to strongly agree (6). In the original study, the Cronbach's alpha obtained was 0.89.

It consists of 17 items divided into two subscales designed to rate auditory hallucinations and delusions. In this study, only the delusion subscale (PSYRATS-D) was used. The Delusion subscale measures various dimensions of delusion through 6 items divided into emotional characteristics (distress) and cognitive interpretation subscales. The first subscale is for cognitive interpretation (4 items) includes Amount of preoccupation with delusions, Duration of preoccupation with delusions, Conviction, and Disruption to life caused by beliefs. The second subscale is for emotional distress of delusions (2 items) Amount of Distress, and Intensity of Distress. The PSYRATS-AH was rated on a five-point Likert scale ranging from 0 (not endorsing the item) to 4 (fully endorsing the item). With a total score range from 0 to 24. The PSYRATS-D has been found to have high inter-rater reliability (0.99-1) and test-retest reliability (r = 0.70).
