Outcome measures
Primary outcome
Comparing implicit cognitions at temptation assessments vs. random assessments.
Secondary outcome
The feasibility of the methodology will be ascertained from the 1) mean
response rate (compliance) on random assessments; 2) mean assessment completion
time; 3) participants* reports on ease of completion; and 4) rate of loss of
PDAs (if any).
Background summary
There has been much recent interest in the role of cognitive processes
underlying addiction. Research among smokers showed that these are important
predictors of relapse. At the same time, there has been growing interest in the
use of handheld computers (PDAs) to collect behavioral data in an Ecological
Momentary Assessment (EMA) setting. EMA has been used successfully in a variety
of psychiatric populations, including impulsive patients, depressives, and
schizophrenics (Moskowitz, & Young, 2006). In the present study, implicit
cognitive assessments (the modified Stroop task and the Implicit Association
Test) will be implemented on PDAs in an EMA setting (clinic).
Study objective
Aim 1: To examine whether implicit cognitions are associated with temptations
to use heroin during a week in the detoxification department.
Aim 2: To ascertain the feasibility of measuring implicit/explicit cognitions
on PDAs in heroin-abusing participants in a clinical setting.
Study design
The study will take place on a detoxification department of an addiction
treatment center. After 4 days, when the physical withdrawal symptoms have
waned, participants will be trained how to use the PDA and will carry this
around for 1-week during detoxification. They will be required to respond to
four random assessments (on a random list) per day, including the modified
Stroop task and the Implicit Association Test (IAT). For the Stroop task,
participants are required to classify the colors of neutral and
addiction-related words as quickly and as accurately as possible. The IAT is
used to investigate automatic affective associations in memory, where
participants are required to categorize a concept (e.g., heroin + pleasant).
Participants will also be required to complete assessments when they experience
temptations to use heroin (*temptation assessments*).
