An Eval of Neurocognitive Function, Oxidative Damage, and Their Association With Outcomes in METH and Cocaine Abusers.

An Evaluation of Neurocognitive Function, Oxidative Damage, and Their Association With Treatment Outcomes in Methamphetamine and Cocaine Abusers

The purpose of this study is to determine whether performance on neurocognitive measures predicts treatment outcomes in individuals with substance abuse disorders. A second purpose is to compare the risk of damage, as well as actual damage, to DNA and other cell parts in people with substance abuse disorders to that of people who do not have substance abuse disorders.

Descrição detalhada

The primary objective of this study is to replicate the finding that performance on the Stroop color-word interference task is predictive of treatment completion in participants with cocaine use disorders and to extend this finding to participants with Methamphetamine use disorders. Secondary objectives include evaluating whether:

performance on various neurocognitive measures, including the Stroop, Rey Auditory-Verbal Learning Test (RAVLT), Iowa Gambling Task (GT), Wisconsin Card Sorting Task (WCST), the Barratt Impulsiveness Scale version -11 (BIS-11), and the Frontal Systems Behavior Scale (FrSBe) is predictive of treatment attrition and stimulant use outcomes in METH/cocaine abusers;
neurocognitive test performance is associated with oxidative damage, a severe consequence of oxidative stress, in METH/cocaine abusers;
oxidative damage is predictive of treatment attrition and substance use outcomes in METH/cocaine abusers,
oxidative damage in METH/cocaine abusers is significantly greater than that of a normal comparison group and
exploratory analyses reveal a significant relationship among oxidative stress, neurocognitive function, and treatment outcomes in METH/cocaine abusers.

Coortes e Intervenções

Grupo / Coorte
METH and/or cocaine dependent group The METH and/or cocaine dependent group were also enrolled in CTN0031 (NCT00573183) and seeking treatment. This group will be analyzed based on whether or not they completed treatment as defined by the study.
Non METH and/or cocaine dependent group The Non METH and/or cocaine dependent group participants are normal controls recruited from the community.

O que o estudo está medindo?

Medidas de resultados primários

Medida de resultado	Descrição da medida	Prazo
Stroop Color-word Task Prazo: Single study visit	The primary objective of this study was to replicate the finding that performance on the Stroop color-word interference task is predictive of treatment completion in participants with cocaine use disorders (Streeter et al., 2007) and to extend this finding to participants with methamphetamine use disorders. In the Stroop, the participant is required to name the color of the ink in which a word is printed while inhibiting the overlearned response of reading the word (e.g., the word ''red'' might be printed in blue ink). The number of errors were subtracted from the time required (RT; Reaction Time) for each of the 3 trials, yielding three summary scores. The derived interference score is obtained by subtracting the RT for the first trial from the RT for the third trial.	Single study visit

Medidas de resultados secundários

Medida de resultado	Descrição da medida	Prazo
Barrett Impulsiveness Scale Version 11 (BIS-11) Prazo: Single study visit	The BIS-11 consists of 30 self-report items, with responses in a four-point Likert-type scale (0 - 3)ranging from "Rarely/Never" to "Almost Always/Always" and comprises three domains: Attentional impulsiveness (AI), Motor impulsiveness (MI), and Non-planning impulsiveness (NP); these three domains are summed to yield a total score; higher scores reflect greater impulsivity. The total score was utilized as the BIS-11 predictor measure (possible score range 0 - 90).	Single study visit
Tail Length From the Comet Assay for Oxidative Damage Prazo: Single study visit	The test for oxidative damage was derived from a blood sample which was analyzed for tail length from the comet assay; higher scores reflect greater oxidative damage.	Single study visit
