Warning Signs…
Risk factors…

Males•Suicide is the eighth leading cause of death for all U.S. men.•Males are four times more likely to die from suicide than females. •Suicide rates are highest among Whites and second highest among American Indian and Native Alaskan men. •Of the 24,672 suicide deaths reported among men in 2001, 60% involved the use of a firearm.Females•Women report attempting suicide during their lifetime about three times as often as men.
SUICIDE: Male v. Female
•Overall rate of suicide among youth has declined slowly since ‘92.
•However, rates remain unacceptably high.
•Adolescents and young adults often experience stress, confusion, and depression from situations occurring in their families, schools, and communities.
•Such feelings can overwhelm young people and lead them to consider suicide as a “solution.”
•Few schools and communities have suicide prevention plans that include screening, referral & crisis intervention programs for youth.
SUICIDE: Youth
•Suicide is the third leading cause of death among young people ages 15 to 24.
•Of the total number of suicides among ages 15 to 24 in 2001, 86% were male and 14% were female.
•American Indian and Alaskan Natives have the highest rate of suicide in the 15 to 24 age group.
•In 2001, firearms were used in 54% of youth suicides.
SUICIDE: Youth
•Previous suicide attempt(s) •History of mental disorders, particularly depression •History of alcohol and substance abuse •Family history of suicide •Family history of child maltreatment •Feelings of hopelessness •Impulsive or aggressive tendencies •Barriers to accessing mental health treatment

•Loss (relational, social, work or financial) •Physical illness •Easy access to lethal methods •Unwillingness to seek help due to stigma•Local epidemics of suicide •Isolation - feeling cut off from other people
The first step in preventing suicide is to identify and understand the risk factors.
SUICIDE: Risk Factors
•Effective clinical care•Easy access to clinical interventions & support•Family and community support •Medical & mental health care relationships•Problem solving, conflict resolution skills•Cultural & religious beliefs/support
SUICIDE: Protective FactorsProtective factors buffer people from the risks associated with suicide. A number of protective factors have been identified:
III. Somatoform Disorders
Also know as Hysteria (Freud)
Conditions involving physical complaints or disabilities that occur without physical pathology
NOT psychosomatic disorders…
Conversion Disorder Hypochondriasis
Conversion Disorder
Conversion of emotional difficulties into the persistent loss of a physiological function

Not faking a physical problem
Cannot be explained physically
Hypochondriasis & Somatization Disorders

IV. Dissociative Disorders
Dissociation…the human mind’s capacity to mediate complex mental activity in channels split off from or independent of conscious awareness

VII. Other Axis I Disorders
Eating DisordersSleep DisordersDisorders of childhood and adolescence Autism, ADHD, Tourette’s, Conduct Disorder

Ego-syntonic…not a problem for the person A problem for others
Resistant to treatment (only behavioral)
FOCUS Antisocial, Narcissistic, OCPD
OCPD symptoms tend to appear early in adulthood and are defined by inflexibility, close adherence to rules, anxiety when rules are transgressed, and unrealistic perfectionism. A person with obsessive compulsive personality disorder exhibits several of the following symptoms:
•abnormal preoccupation with lists, rules, and minor details
•excessive devotion to work, to the detriment of social and family activities
•miserliness or a lack of generosity
•perfectionism that interferes with task completion, as performance is never good enough
•refusal to throw anything away (pack-rat mentality)
•rigid and inflexible attitude towards morals or ethical code

Disorder
Psychopathology & The Law
Competence to Stand Trial Can individual participate in own defense at
time of trial?

will due to imminent danger? Suicidal or homicidal Decided by doctor, then court; need evidence
More Legal Issues…State-level
Insanity Plea Should individual not be held accountable due
to their mental state at the time of the crime? Could not determine right from wrong
Determined by judge before actual trial Difficult to prove, but prevalent in media Sent for treatment, then released
*Insanity is a LEGAL term…!
More Legal Issues…State-level
Guilty but Mentally Ill Alternative to insanity plea in some states Adopted by Pennsylvania… 1st trial determines guilt or innocence 2nd trial determines sanity or insanity Sent for treatment, then to prison to complete
sentence…get treatment as well as punishment
•Cognitive therapy identifies habitual ways in which patients distort information (e.g. automatic thoughts) and teaches patients to identify, evaluate, and respond to their dysfunctional thoughts and beliefs, using a variety of techniques to change thinking, mood, and behavior. Cognitive therapy is a structured, goal oriented, problem focused, and time limited intervention.
TYPES OF PSYCHOTHERAPY — A number of types of psychotherapy are used to treat psychological disorders:
•Behavioral therapy attempts to alter behavior by systematically changing the environment that produces the behavior. Behavioral changes are believed to lead to changes in thoughts and emotions.
•Exposure-based behavioral treatments utilize gradual, systematic, repeated exposure to the feared object or situation to allow patients with anxiety disorders to become desensitized to the feared stimulus.
TYPES OF PSYCHOTHERAPY
•Cognitive Behavioral therapy (CBT) combines principles of both behavioral and cognitive therapy, focusing simultaneously on the environment, behavior, and cognition. Cognitive behavioral therapy is also structured, goal directed, problem focused. Patients learn how their thoughts contribute to symptoms of their disorder and how to change these thoughts. Increased cognitive awareness is combined with specific behavioral techniques.
TYPES OF PSYCHOTHERAPY
•Problem Solving therapy, a short-term, cognitive behavioral intervention, teaches a systematic method for solving current and future problems. Patients acquire new skills for successfully resolving interpersonal difficulties. These skills include the following sequential steps: 1) Problem definition; 2) Goal setting; 3) Generating, choosing, and implementing solutions; and 4) Evaluating outcomes.
TYPES OF PSYCHOTHERAPY
•Interpersonal therapy addresses issues such as grief, role transitions, interpersonal role disputes, and interpersonal deficits as they relate to the patient's current symptoms.
•Family therapy attempts to correct distorted communications and relationships as a means of helping the entire family, including the identified patient. In patients with serious mental illness, such as schizophrenia, family therapy helps family members learn about the disorder, solve problems, and cope more constructively with the patient's illness.
TYPES OF PSYCHOTHERAPY
•Psychoeducation provides patients with information about their diagnosis, its treatment, how to recognize signs of relapse, relapse prevention, and strategies to cope with the reality of prolonged emotional or behavioral difficulties.
•The goal of psychoeducation is to reduce distress, confusion, and anxiety within the patient and/or the patient's family to facilitate treatment compliance and reduce the risk of relapse.
•Psychoeducation is often particularly helpful for patients and the families of patients with chronic, severe psychiatric disorders such as schizophrenia and bipolar disorder.
