What is the CSSA? Cocaine Selective Severity Assessment - It is a measure of cocaine withdrawal - It is a measure of cocaine withdrawal - 18 Item each measured on a 0-7 scale - 18 Item each measured on a 0-7 scale - Signs and symptoms measured include: - Signs and symptoms measured include: appetite changessleep changes appetite changessleep changes cocaine cravingdepressed mood cocaine cravingdepressed mood anxiety irritability anxiety irritability lethargy inattention lethargy inattention paranoia heart rate changes paranoia heart rate changes

Where did the CSSA come from? CSSA written by Joe Volpicelli at Penn CSACSSA written by Joe Volpicelli at Penn CSA Modeled on the Selective Severity Assessment for alcohol (Gross 1973)Modeled on the Selective Severity Assessment for alcohol (Gross 1973) Intended to assist in the management of cocaine withdrawal syndromeIntended to assist in the management of cocaine withdrawal syndrome

Cocaine withdrawal as a syndrome Gawin and Kleber Arch Gen Psychiatry 1986;43:

Cocaine withdrawal and subjective effects Depression increases cocaine high (Uslaner, 1999; Sofuoglu, 2001) Irritability increases cocaine high (Newton, 2003) Cocaine Withdrawal Increases the Cocaine High

Cocaine withdrawal and subjective effects Cocaine Withdrawal Increases the Cocaine High Sofuoglu et al. Drug Alcohol Depend 2003; 69:

Cocaine withdrawal and hedonic dysregulation Several studies report that the presence of severe cocaine withdrawal symptoms at baseline predicts poor clinical outcome Craving Hedonic Dysregulation WD

The CSSA 18 Items Interviewer administered 2 craving scales One total score

Psychometric testing Initial reliability and validity testing 1.Test retest reliability 2.Interrater reliability 3.Internal consistency 4.Concurrent validity 5.Predictive validity Kampman et al. Addict Behav (4):

CSSA: concurrent validity Individual items correlate with DSM-IV criteria Depressed moodDepressed mood LethargyLethargy Increased appetiteIncreased appetite Increased sleepIncreased sleep IrritabilityIrritability

CSSA: concurrent validity Individual items correlate with ASI severity measures –More days of cocaine use –Longer lifetime history of cocaine use –Higher ASI Severity scores for drug problems

CSSA: concurrent validity Specific to cocaine withdrawal Specific to cocaine withdrawal

CSSA: concurrent validity Scores decline over time if a patient becomes abstinent Scores decline over time if a patient becomes abstinent

CSSA as an outcome measure CSSA Scores in Treatment Mean CSSA scores tend to decline over time in medication trials No differences in CSSA scores over time in several trials topiramate modafinil acamprosate naltrexone (oral) naltrexone (extended release injectable) varenicline piracetam disulfiram olanzapine ginko biloba theobromine amantadine *propranolol – reduced withdrawal symptoms in 1 st trial not 2 nd

Discussion The CSSA is an good predictor of outcome in outpatient cocaine dependence treatmentThe CSSA is an good predictor of outcome in outpatient cocaine dependence treatment The CSSA may identify subgroups responsive to particular medications – propranolol and topiramate for exampleThe CSSA may identify subgroups responsive to particular medications – propranolol and topiramate for example No medication tested has shown a differential response in reducing CSSA scores.No medication tested has shown a differential response in reducing CSSA scores.
