Suicidal ideation was associated with depressed mood, anxiety, low self-esteem, negative illness perceptions, negative evaluative beliefs about the self and others and daily alcohol consumption. Frequency of auditory hallucinations and preoccupation with delusions were not associated with suicidal ideation; however, positive symptom distress did relate to suicidal thoughts.Conclusion: Affective dysfunction, including distress in response to hallucinations and delusions, was a key factor associated with suicidal ideation in individuals with psychotic relapse. Suicidal ideation in psychosis appears to be an understandable, mood-driven process, rather than being of irrational or 'psychotic' origin. %J ACTA PSYCHIAT SCAND %V 114 %A L Fialko %A D Freeman %A PE Bebbington %A E Kuipers %A PA Garety %A G Dunn %A D Fowler %D 2006 %N 3 %T Understanding suicidal ideation in psychosis: findings from the Psychological Prevention of Relapse in Psychosis (PRP) trial %L discovery2181 %P 177 - 186
