The DSM-IV Definition of Trauma: • “Criterion A.: The person has been exposed to a[n]…event in which both of the following were present: • “1. The person experienced, witnessed, or was confronted with an event or events that involved actual or threatened death or serious injury, or a threat to the physical integrity of self or others….
DSM-IV Trauma: • “2. The person’s response involved intense fear, helplessness or horror…” • from: American Psychiatric Association, Diagnostic and Statistical Manual, 4th Edition--Text Revision, 2000.
DSM-IV Post-traumatic Stress Disorder (PTSD) • At least 1 re-experiencing symptom: • “Classic” PTSD Symptoms • Nightmares (or evidence thereof) • Flashbacks • Intrusive memories • Physiological reactivity with reminders • Cue-related distress
DSM-IV Post-traumatic Stress Disorder (PTSD) • At least 3 symptoms of avoidance, numbing and estrangement: • Avoidance of internal or external cues • Emotional estrangement • Emotional numbing
DSM-IV Post-traumatic Stress Disorder (PTSD) • Avoidance symptoms, cont’d: • Decreased interest in pleasurable or usual activities • Psychogenic amnesia • Sense of a foreshortened future
DSM-IV Post-traumatic Stress Disorder (PTSD) • At least 2 symptoms of hyperarousal; • Sleep disturbances • Hyperstartle • Irritability or anger outbursts • Hypervigilance • Decreased concentration
DSM-IV Post-traumatic Stress Disorder (PTSD) • Duration and Impairment Criteria: • Occurring > 1 month post-trauma • Lasting > 1 month • Interfering with function
Subsyndromal PTSD • Also known as “partial PTSD” • No single, agreed-upon definition, but most commonly: • 2 out of 3 symptom cluster criteria, or • 1 intrusive-cluster symptom and meeting full criteria for another symptom cluster • Stein et al (1997) Am J Psychiatry,154(8):1114-1119
Diagnostic Instruments • Interviews: • Clinician Administered PTSD Scale • Structured Clinical Interview for DSM-IV (SCID) PTSD module • Structured Interview for PTSD
Diagnostic Instruments • Self-administered questionnaires: • Posttraumatic Diagnosis Scale • Coffey et al (1998): validation among detox patients • Impact of Event Scale-Revised • Davidson Traumatic Stress Scale • PTSD Checklist
Outline of Presentation: • I. Terminology • II. Epidemiology and Comorbidity • III. Neurobiology and Treatment Approaches
National Comorbidity Survey • PTSD prevalence: 5% males,10% female • Among those with PTSD: • Alcohol use disorders prevalence: 51.9% (OR=2.06) among males; 27.9% among females (OR=2.48) • Drug use disorders (excl nicotine): 34.5% (OR=2.97) among males, 26.9% (OR=4.46) among females Kessler et al. (1995) Arch Gen Psychiatry 52:1048-1060
Rates of PTSD-Substance Use Disorders in Specific Samples • 14% among community Gulf war veterans • 20% among mixed-gender substance abuse outpatients (Triffleman, et al 1995) • Typically cited rates:30-50% • 59% among community women in the South Bronx (Fullilove, 1993)
Rates of PTSD, Cigarette Use • Beckham et al (1997): N=445 male VN Vets: • Combat vets with PTSD smoked more cigarettes than combat vets without PTSD • 48% of PTSD+ vets vs 28% of PTSD- vets smoked >25 cigs per day
Medical problems and PTSD • Higher rate of medical problems, including: • HTN • Chronic pain disorders • Heart disease • GI disorders
Medical problems and PTSD • Higher rate of HIV risk behaviors • Kimmerling, et al (1998): Higher than expected rates of PTSD among HIV+ women • Higher rate of mortality
Disorders co-occuring with PTSD and addiction • Major depression and dysthymia • Anxiety disorders (panic disorder, social phobia) • Psychotic disorders • Borderline, antisocial personality disorders • Dissociative disorders
Outline of Presentation: • I. Diagnosis and Screening • II. Epidemiology and Comorbidity • III. Neurobiology and Treatment Approaches
Neurobiology of PTSD • Increased catecholamines, decreased alpha-2 adrenergic receptors • HPA disturbances: decreased glutocorticoid levels, increased glutocorticoid receptors • Increased central corticotropin-releasing factor
Neurobiology of PTSD • Serotonergic dysfunction • Reduced beta-endorphin levels and increased pain thresholds
Brain Activation Changes in PTSD Hendler et al (2003) NeuroImage, 19: 587-600
Psychopharmacotherapy for the Dually Diagnosed • Treating the nonsubstance Axis I disorder: • The nonsubstance Axis I disorder improves • The substance use disorder may improve, but does not go into remission • Treatment retention improves • May have a durable effect, even after discontinuation
Psychopharmacotherapy for the Dually Diagnosed • Treating the Substance Use Disorder: • Any medication useful for the treatment of addiction is useful in the treatment of dually diagnosed individuals • But that does not mean there is a specific psychotropic effect beyond anti-addiction mechanism and decrease in substance-induced psychiatric symptoms
Psychopharmacological Approaches • In PTSD, medications are part of an integrative strategy • As with psychotherapy, everything has been tried
Psychopharmacological Approaches • Antidepressants • RCT’s done in PTSD on: • SSRI’s (Fluoxetine, Paroxetine, Sertraline) • SSNRI (Mirtazapine) • TCA (Amitryptyline, Imipramine) • MAOI (Phenelzine, brofaromine)
Psychopharmacological Approaches • Mood-stabilizing anticonvulsants (anti-glutaminergic): • RCT on lamotrigine • Atypical antipsychotics • RCT’s on risperidone, quetiapine
Psychopharmacological Approaches • Anti-adrenergic agents • RCT on Prazosin • Clonidine used frequently in children
Psychopharmacological Approaches • Benzodiazepines: • 1 RCT: Alprazolam vs placebo, 3.75 mg qD: no effect on core PTSD symptoms
Benzodiazepines in PTSD • depends on the setting, the disorder and the patient • Appropriate for use in intensive settings for treatment of acute exascerbations of PTSD and for detoxification—but still must make a clear decision regarding continuation prior to discharge • Should be used with caution in other settings and for other purposes
Pharmacotherapy for PTSD-SUDs: • A case series regarding sertraline (Zoloft): • N=9 civilian male and female subjects • Current alcohol dependence+PTSD • The severity of both PTSD and alcohol dependence symptoms declined significantly over the course of the 12-week trial in 6 treatment-completers. • Brady et al (1995) J Clin Psychiatry 56:502-505
Research Trials in PTSD: without SUDs? • Many of the trials have included those with concurrent PTSD-SUDs • Marks et al (1998): 17% of subjects were alcohol dependent • Resick (2002): excluded subjects with substance dependence, advised substance abusing subjects not to use while in treatment • Outcomes for those with SUDS unknown
Impact of Concurrent Treatment of PTSD-SUDs • Male veterans were at least partially in alcohol use remission if they had attended PTSD specialty clinics > 2x/month in addition to regularly attending substance-abuse treatment facilities at 2 years’ follow-up. • Ouimette PC et al (2000). J Stud Alcohol, 61:247-253.
Impact of Concurrent Treatment of PTSD-SUDs • Remission for SUDs was 3.7 times more likely in those subjects in treatment for PTSD during Year 1, after controlling for outpatient addiction treatment • Ouimette PC et al (2003) Journal of Consulting and Clinical Psychology, 71:410-414
Psychosocial Approachesin PTSD with SUDs • How does one address the trauma? • Discuss the trauma-related deficits • Discuss the events of the trauma • Discuss the meaning of the trauma • All or some
Psychosocial Approachesin PTSD with SUDs • When does one address the trauma? • Never • First • Last • Throughout
Integrated Treatments for PTSD –Substance Use Disorders • Several clinical approaches described, most for outpatients, 1 residential-based treatment • Donovan et al (2001): male vets; completed rehab for SUDS prior to treatment entry; multiple treatment techniques used • Decreases in PTSD severity and number of days of substance use • Donovan, Padin-Rivera, &Kowaliw (2001) J Traumatic Stress, 14:757-772.
Research-based Psychosocial Treatment for PTSD-SUDS • A few have been rigorously tested: • Triffleman et al: Substance Dependence PTSD Therapy (SDPT)=Assisted Recovery from Trauma and Substances • Najavits et al: Seeking Safety • Back, Brady et al: Concurrent Treatment of PTSD and Cocaine Dependence
Research-based Psychosocial Treatment for PTSD-SUDS • Assisted Recovery from Trauma and Substances (ARTS; as SDPT, Triffleman et al 1998, 2000, 2001) Manualized Cognitive-Behavioral Treatment with careful attention to transference and countertransference issues
Assisted Recovery from Trauma and Substances • Phased, sequential treatment • Throughout: weekly – twice weekly urine toxicology screening
ARTS • Phase I (week 1-12): • Substance use-focused, trauma-informed, with emphasis on reduction of substance use, based on Carroll’s (1993) Cognitive-Behavioral Coping Skills Therapy • PTSD psychoeducation • PTSD and addiction-related coping skills, including relaxation training, anger management, assertiveness among others • Tacit motivational enhancement
ARTS • Phase II (weeks 13 and on): • Stress Inoculation • Prolonged exposure, adapted for work with the actively addicted by a) fewer repetitions each session; b) active discussion after each PE; c) no tapes for homework.
ARTS • In-vivo exposure (homework) • Could be started before or after onset of prolonged exposure, based on individual needs and comprehension • Continued urine tox testing, continued therapist active query and attention to substance use, craving, triggers (including treatment sessions) etc.
ARTS • 5 months duration • Twice-weekly hour-long sessions • Individual therapy • Outpatients
Research-based Psychosocial Treatments for PTSD-SUDs • Najavits et al 1996: Seeking Safety • Integrative method based on Judith Herman’s work • 12-week, group therapy, 1.5 hours 2x/week • Emphasis on cognitive and coping skills approaches • No direct discussion of the specifics of traumatic events
