RESUMEN
BACKGROUND: Individuals experiencing psychosis can present with elevated levels of depression and anxiety. Research suggests that aspects of depression and anxiety may serve an avoidant function by limiting the processing of more distressing material. Acceptance and Commitment Therapy suggests that avoidance of aversive mental experiences contributes to psychological inflexibility. Depression and anxiety occurring in the context of psychosis have a limiting effect on quality of life. No research to date has investigated how levels of psychological flexibility and mindfulness are associated with depression and anxiety occurring following psychosis. AIMS: This study investigated associations psychological flexibility and mindfulness had with depression and anxiety following psychosis. METHOD: Thirty participants with psychosis were recruited by consecutive referral on the basis that they were experiencing emotional dysfunction following psychosis. The Hospital Anxiety and Depression Scale (HADS), Positive and Negative Syndrome Scale (PANSS), Acceptance and Action Questionnaire (AAQ-II) and the Kentucky Inventory of Mindfulness Skills (KIMS) were used. A cross-sectional correlational design was used. RESULTS: The depression and anxiety subscales of the HADS both had significant correlations with psychological flexibility (as assessed by the AAQ-II) and aspects of mindfulness (as assessed by the KIMS). Hierarchical regression analyses indicated that psychological flexibility, but not mindfulness, contributed significantly to models predicting 46% of variance in both depression and anxiety scores. CONCLUSIONS: Although aspects of mindfulness are associated with depression and anxiety following an episode of psychosis, psychological flexibility appears to account for a larger proportion of variance in depression and anxiety scores in this population.

The experience of psychosis can lead to depression, anxiety and fear. Acceptance and Commitment Therapy (ACT) facilitates individuals to accept difficult mental experiences and behave in ways that are consistent with personally held values. This study was a single (rater) blind pilot randomised controlled trial of ACT for emotional dysfunction following psychosis. Twenty-seven participants with psychosis were randomised to either: ten sessions of ACT plus treatment as usual (TAU) or TAU alone. The Hospital Anxiety and Depression Scale, Positive and Negative Syndrome Scale, Acceptance and Action Questionnaire, Kentucky Inventory of Mindfulness Skills and Working Alliance Inventory were used. Individuals were assessed at baseline and 3 months post-baseline. The individuals randomised to receive ACT found the intervention acceptable. A significantly greater proportion of the ACT group changed from being depressed at time of entry into the study to not being depressed at follow-up. The ACT group showed a significantly greater increase in mindfulness skills and reduction in negative symptoms. Results indicated that individuals randomised to ACT had significantly fewer crisis contacts over the study. Changes in mindfulness skills correlated positively with changes in depression. ACT appears to offer promise in reducing negative symptoms, depression and crisis contacts in psychosis.
