Psychosis is a mental or psychiatric disorder characterized by hallucinations, delusions, chaotic behavior, and accompanied by poor insight. A systematic review and meta-analysis study showed that individuals with a diagnosis of psychosis have a high prevalence of suicide. One of the psychotherapies given to psychosis clients with suicide risk is cognitive therapy (CT). Objective: To determine the effect of cognitive therapy (CT) on psychosis clients with suicide risk Articles discussed in this literature review were obtained through article searches in electronic journal databases, namely Science Direct, ProQuest, Wiley Online Library, EBSCOhost, Sage Journals, and ClinicalKey. The inclusion criteria of this journal review were human studies, English, and free fulltext. The results showed that CT in clients at risk of suicide has a significant effect in reducing suicide risk through mechanisms to correct thought distortions and build positive thoughts and beliefs to produce adaptive coping mechanisms. This study has implications for the importance of applying cognitive therapy as part of psychotherapeutic interventions for clients with psychosis who are at risk of suicide. This therapy not only helps reduce symptoms associated with psychosis, but also plays a role in reducing suicidal tendencies by correcting maladaptive thoughts and beliefs.
