How does attachment style affect psychosis? A␣systematic review of causal mechanisms and guide to future inquiry.

The relationship between attachment and psychosis is now well established, and studies have started to examine mediating mechanisms. Affective and cognitive factors mediate the attachment-psychosis relationship. Affective factors differ by attachment style. There is limited evidence for the duration of untreated psychosis and negative psychotic symptoms as mediating mechanisms, and research replication is needed. Cognitive factors are routinely targeted in recommended psychological therapies for psychosis, but affective factors and attachment style are less commonly considered. Research should be conducted into the effectiveness of psychological therapies which calibrate cognitive and affective interventions, according to attachment style.
