Objectives

• Review descriptive epidemiology of suicidal ideation, attempts, and completion

• Review risk factors for suicidality across the life span and diagnostic groups

• Use risk factors for purposes of suicide risk assessment

• Review management and treatment of patients who are suicidal or at high risk for suicide

Assessment of Suicidal Patients

• Characteristics of suicidality

• Current and lifetime psychopathology

• Psychological characteristics

• Family and environmental factors

• Availability of lethal agents

Page 10: Suicide Risk: Comprehensive Assessment and Clinical Management David A. Brent, M.D. Western Psychiatric Institute and Clinic March 28, 2006

Characteristics of Suicidality

• Intent / current ideation

• Lethality

• Precipitant

• Motivation

• Environmental response

Page 11: Suicide Risk: Comprehensive Assessment and Clinical Management David A. Brent, M.D. Western Psychiatric Institute and Clinic March 28, 2006

Suicidal Intent• “Wish to die”— based on self-report of

observable behavior

• Belief about intent

• Preparatory behavior

• Prevention of discovery

• Communication of intent

• Higher in completers than attempters

• Predicts reattempt and completion

Page 12: Suicide Risk: Comprehensive Assessment and Clinical Management David A. Brent, M.D. Western Psychiatric Institute and Clinic March 28, 2006

Assessment of Suicidal Ideation

• Have you ever thought you would be better off dead?

• Do you have thoughts of wanting to hurt yourself? (intensity and frequency)

• Do you have a plan?

• Do you intend to carry it out?

• What things keep you from acting on your thoughts (Reasons for Living)?

• What things would increase the likelihood of trying to hurt yourself?

Page 13: Suicide Risk: Comprehensive Assessment and Clinical Management David A. Brent, M.D. Western Psychiatric Institute and Clinic March 28, 2006

Current Suicidal Ideation / Past Behavior

• Intensity, now and worst ever

• Frequency

• Presence of active plan

• Wish to carry out plan

• Past history of attempt particularly within the past 6 months

Page 14: Suicide Risk: Comprehensive Assessment and Clinical Management David A. Brent, M.D. Western Psychiatric Institute and Clinic March 28, 2006

Progression of Suicidality*

Ideation to plan 34%

Ideation to attempt 26% (90% in 1 yr)

Plan to attempt 72% (60% in 1 yr)

*Kessler et al., 1999

Page 15: Suicide Risk: Comprehensive Assessment and Clinical Management David A. Brent, M.D. Western Psychiatric Institute and Clinic March 28, 2006

Lethality• Modestly associated with intent

• But impulsive acts can be very lethal

• Children can have high intent and low lethality

• High lethality is associated with higher risk of completion

• Availability of lethal agents important in younger, impulsive suicides

• Ratio of attempts to completions drops with age

Page 16: Suicide Risk: Comprehensive Assessment and Clinical Management David A. Brent, M.D. Western Psychiatric Institute and Clinic March 28, 2006

Non-Suicidal Self-Harm

• Self-cutting, repetitive and stereotypical

• To relieve distress/anger, pain, loneliness rather than to die

• Often co-occurs with suicidal behavior

Page 17: Suicide Risk: Comprehensive Assessment and Clinical Management David A. Brent, M.D. Western Psychiatric Institute and Clinic March 28, 2006

Precipitants

• Abuse

• Family discord

• Romantic attachment disruption

• Legal/disciplinary problems

• Disruption of relationship very high risk for alcoholic suicides

• Bereavement very important factor in geriatric suicidal behavior

• Assess likelihood of recurrence

Page 18: Suicide Risk: Comprehensive Assessment and Clinical Management David A. Brent, M.D. Western Psychiatric Institute and Clinic March 28, 2006

Motivation• Wish to die or permanently escape

psychological painful situation(1/3 in younger individuals, but increases with age)

• To influence others

• Get attention

• Express hostility

• Induce guilt

Page 19: Suicide Risk: Comprehensive Assessment and Clinical Management David A. Brent, M.D. Western Psychiatric Institute and Clinic March 28, 2006

Psychopathology

• Over 80% of attempters and 90% of completers have at least one Axis I disorder

• Most commonly mood disorder

• High risk for bipolar disorder, particularly mixed state

• Substance abuse

• Cluster B disorders

• Schizophrenia

• Comorbidity, chronicity, severity

Page 20: Suicide Risk: Comprehensive Assessment and Clinical Management David A. Brent, M.D. Western Psychiatric Institute and Clinic March 28, 2006

Age and Suicide• Suicide attempts and ideation more common in

the young

• Younger suicides more often involve Cluster B, substance abuse, impulsivity, aggression

• Depression, schizophrenia-- suicide occurs relatively early in course

• “Pure” depression and planned suicide more common in older adults

• Alcoholics tend to commit suicide later in the course of the disorder

Page 21: Suicide Risk: Comprehensive Assessment and Clinical Management David A. Brent, M.D. Western Psychiatric Institute and Clinic March 28, 2006

Prediction of Suicide Attempt in Community

Samples*• Demographic: Age 15-24, female, <12 years old

• Psychiatric: Mood disorder, psychoses, PTSD, substance abuse, ASP

• Those with 3+ risk factors are 9.2% of population, but make up 55.1% of all attempters

*Kessler et al., 1999

Page 22: Suicide Risk: Comprehensive Assessment and Clinical Management David A. Brent, M.D. Western Psychiatric Institute and Clinic March 28, 2006

Psychological Characteristics

• Hopelessness (dropout, poor treatment response, attempt)

• Impulsivity and aggression (strong predictor of suicidal behavior, especially in presence of a mood disorder, familial component) - More important in suicide earlier in life

• Social skills deficits (interpersonal problems)

• Homosexuality, bisexuality (bullying, family rejection)

• Inflexibility (in older suicides)

Page 23: Suicide Risk: Comprehensive Assessment and Clinical Management David A. Brent, M.D. Western Psychiatric Institute and Clinic March 28, 2006

Family and Social Factors

• Parental history of psychiatric illness and suicidal behavior

• Abuse and neglect

• Discord

• Disruption of interpersonal relationships

• Grief

• Disconnection and “drifting”

Abuse and Neglect• Related to attempt and completed suicide

• Sexual abuse prominent in early-onset disorders and attempts

• Parental history of sexual abuse increases risk of attempt in offspring

• Risk related to severity of abuse

• Leads to cascade of mental health difficulties: early sexual activity, sexual assault, early pregnancy, marriage, divorce

• Adversely affects course, adherence to treatment, response to treatment

Page 27: Suicide Risk: Comprehensive Assessment and Clinical Management David A. Brent, M.D. Western Psychiatric Institute and Clinic March 28, 2006

Page 28: Suicide Risk: Comprehensive Assessment and Clinical Management David A. Brent, M.D. Western Psychiatric Institute and Clinic March 28, 2006

Protective Factors in Adults• Supportive family

• Live with other people (spouse, child)

• Children at home

• Sense of connection and support

• In older people, “pride in aging”

• Sense of purpose

Page 29: Suicide Risk: Comprehensive Assessment and Clinical Management David A. Brent, M.D. Western Psychiatric Institute and Clinic March 28, 2006

Why Target Depression?

• 80% of attempters and 60% of completers are depressed

• Depression increases the risk for suicidal behavior 10- to 50-fold

• Quality improvement studies also suggest that improved treatment of depression reduces suicidality risk (Asarnow et al., 2005; Wells et al., 2001; Brown et al., 2001)

• Pharmacoepidemiological studies show reduction in suicide with SSRI use

Page 57: Suicide Risk: Comprehensive Assessment and Clinical Management David A. Brent, M.D. Western Psychiatric Institute and Clinic March 28, 2006

Treatment of Depression Reduces Suicidal Risk

• Gotland study – Improvement in GPs ability to treat depression resulted in decreased suicide rate

• PROSPECT – Collaborative care for depressed suicidal elders was more effective than TAU for reducing suicidality

• Pharmaco-epidemiology studies – Increase in SSRI prescription related to decline in suicide, particularly in 15-24 year-olds

Treatment of Depression May NotReduce Suicidal Risk

• The most suicidal individuals are excluded from clinical trials of depression

• Suicidality is associated with other factors that also predict treatment non-response of depression (chronicity, severity, comorbidity, personality disorder)

Changes in Mood and Suicidality Not

Always Closely Related

• Suicidal behavior is multifactoral

• Studies of CBT, IPT, antidepressants differentially decrease depression, but not suicidal ideation, attempts (Brent, 1997; Lerner, 1990; Mufson, 1999; Khan et al., 2000; Storosum et al., 2001)

• Studies that decrease suicidal ideation / attempts do not affect mood (Linehan, 1991; Harrington, 1998; Wood, 2001)

• SSRIs may increase suicidal risk

SSRIs and Suicidality: A Summary of the FDA Findings

• Rate of “suicidality” increased 1.78-fold

• On average drug vs. placebo, 4% vs. 2%

• Mostly new or worsened ideation, few attempts, no completions – question clinical significance

• Early in treatment

• Most common in trials that also showed increase in hostility

• No difference in ideation on standard measures

• More pronounced in non-depressed (e.g., anxious, OCD) subjects

Treatment Studies with Suicidal Youth

Harrington et al. (1998) – Home-based family intervention no better than TAU for adolescent overdose attempts. In non-depressed group family treatment reduced ideation

Wood et al (2001) – 6-session group treatment >TAU for reducing single (OR=.6) and recurrent attempts (OR=.16), anger, and conduct disorder, but not depression. More of experimental treatment better, more of TAU worse.

TASA (Treatment of Adolescent Suicide Attempters) CBT

• Safety plan

• Case management

• Chain analysis of attempt

• Focus on cognitions leading to attempt

• Two-fold reduction in re-attempt in Brown et al. (2005)

• Now being tested in multi-site study of adolescent attempters funded by NIMH

Page 83: Suicide Risk: Comprehensive Assessment and Clinical Management David A. Brent, M.D. Western Psychiatric Institute and Clinic March 28, 2006

Chain Analysis of Suicide Attempt

• Precipitant

• Motivation

• Negative affect

• Hopelessness

• Emotion regulation

• Environmental response

In setting treatment priorities, ask

(collaboratively):

• What will yield the greatest risk reduction for the least effort?

• Is it something that can be changed?

• Does the patient want to / have the capability to change this factor?

Page 87: Suicide Risk: Comprehensive Assessment and Clinical Management David A. Brent, M.D. Western Psychiatric Institute and Clinic March 28, 2006

Relapse Prevention Session

• Imagine situation that led to attempt

• Role play how would cope now

• Identify skills and resources necessary to stay well

Page 88: Suicide Risk: Comprehensive Assessment and Clinical Management David A. Brent, M.D. Western Psychiatric Institute and Clinic March 28, 2006

Treatment Guidelines

• Establish safety plan

• Increase likelihood of adherence

• Determine appropriate level/intensity of care

• Increase hopefulness about treatment

• Conduct chain analysis of the attempt

• Target most relevant individual and environment factors to the suicide attempt

• Increase protective factors (family connection)

• Coping plan, hope kit

Page 89: Suicide Risk: Comprehensive Assessment and Clinical Management David A. Brent, M.D. Western Psychiatric Institute and Clinic March 28, 2006

Safety Plan

• Will try to implement coping plan

• Promises family and clinician not to engage in suicidal behavior OR

• Will contact clinician/family/responsible adult if suicidal thoughts reoccur

• Need 24-hour availability or back-up

• Review precipitants, develop truce and conduct brief training in emotional regulation

• Secure lethal agents

Page 90: Suicide Risk: Comprehensive Assessment and Clinical Management David A. Brent, M.D. Western Psychiatric Institute and Clinic March 28, 2006
Page 91: Suicide Risk: Comprehensive Assessment and Clinical Management David A. Brent, M.D. Western Psychiatric Institute and Clinic March 28, 2006

Secure Lethal Agents

• Find out motivation for gun ownership

• Find out who owns the gun

• Negotiate most secure situation possible

• Parental regulation of medication

Page 92: Suicide Risk: Comprehensive Assessment and Clinical Management David A. Brent, M.D. Western Psychiatric Institute and Clinic March 28, 2006

Hopelessness

• Address hopelessness about treatment first

• On a scale of 1-10, how hopeful are you that we can help you? What would increase/decrease it?

• Establish concrete, realistic, achievable goals

• Reasons for Living

• Predict “bumps in the road” to prevent undue discouragement

Page 93: Suicide Risk: Comprehensive Assessment and Clinical Management David A. Brent, M.D. Western Psychiatric Institute and Clinic March 28, 2006

Education• Educate parents and families about depression

as a chronic and recurrent illness

• Depression is nobody’s fault

• Help set reasonable expectations regarding chores, school, work

• Often family members are worried and want information and reassurance from a withdrawn and secretive patient

• Goal to teach family and patient how to monitor for treatment response, side effects, and long-term course

Page 94: Suicide Risk: Comprehensive Assessment and Clinical Management David A. Brent, M.D. Western Psychiatric Institute and Clinic March 28, 2006

Recognize Intercorrelation of Health Risk Behaviors

• Unprotected sex

• Alcohol, drug, tobacco use

• Weapon-carrying

• Binge eating and obesity

• Bullying/being bullied

Page 95: Suicide Risk: Comprehensive Assessment and Clinical Management David A. Brent, M.D. Western Psychiatric Institute and Clinic March 28, 2006

Increase Protective Factors

• Improve family-patient connection, supervision, expectations

• Improve school connection (when relevant)

• Choice of friends and romantic attachments / marriage

• Connection to social groups and institutions

Page 96: Suicide Risk: Comprehensive Assessment and Clinical Management David A. Brent, M.D. Western Psychiatric Institute and Clinic March 28, 2006

Education and Anticipation: Relapse and Recurrence

Prevention• Sleep hygiene

• Avoidance of tobacco, alcohol and drugs

• Pleasurable activities

• Self-talk and practice of skills

• Exercise

• Detection of relapse

Page 97: Suicide Risk: Comprehensive Assessment and Clinical Management David A. Brent, M.D. Western Psychiatric Institute and Clinic March 28, 2006
