There are many risk factors that can contribute to suicidal behavior for individuals experiencing psychosis. The risk factors include age, gender, marital status, employment status, previous suicide attempts, presence of psychotic symptoms, depression, social functioning and social isolation and substance use. The time of greatest risk for individuals with psychosis is during the first year of illness which usually occurs during the late teens to early twenties. Risk of suicide is generally high after an episode of psychotic symptoms or up to 6 months after discharge from inpatient treatment. Although young age and early phase of illness are key high-risk factors, suicidal ideation and behavior can happen throughout the lifespan for individuals with psychotic disorders.
Key risk factors for suicide for people experiencing psychosis:
- Males with psychosis are at higher risk than females for completing suicide.
- Females with psychosis are at higher risk for suicide than females in the general population or other high-risk groups.
- Single individuals with psychosis die by suicide more than do individuals who are in relationships which is important because most individuals with psychosis are single.
- Risk of suicide is greater when the individual is unemployed or not engaged with a regular activity such as school or volunteer work. Most individuals with psychosis are unemployed.
- Over 50% of individuals with schizophrenia who die by suicide have made a previous attempt and 50% or more make more than one attempt.
- There is no evidence that suicidal behavior occurs more frequently in response to psychotic symptoms. Rather, suicidal behavior occurs mostly because individuals are distressed or overly preoccupied by the psychotic symptoms they are experiencing.
- About 20% of individuals with psychosis experiencing command hallucinations to kill themselves will act on them.
- Risk for suicidal behavior is increased during a depressive episode, but depressed mood alone is a risk factor. Hopelessness is key risk factor in first-episode psychosis.
- Individuals with poor social functioning may be at greater risk due to lack of problem-solving skills, impulsiveness and aggression, poor social skills, and social isolation.
- Loss of social support especially of family or of a therapist, is a large risk factor.
- Not being able to return home after hospitalization also increases risk.
- Substance use and abuse increases risk especially when combined with a psychotic disorder
- Cognitive inflexibility (“tunnel vision”) and ineffective decision which can interfere with the person’s ability to think of alternatives to suicide, increases risk of suicide.
Research has shown that protective factors are associated with reduced risk of suicide in people with psychotic disorders. Experts have identified several important protective factors.
- An accepting and supportive social environment including family support and acceptance
- Effective problem-solving skills which can help reduce stress
- Feeling like there is a reason for living
- Possessing a positive attitude toward mental health providers and accessibility to care
- Limited access to lethal or deadly means of suicide
- Skills and abilities associated with good pre-morbid functioning
