Instrumentation Of The Abstinence's Likelihood Scale In Drug Addiction (ALSDA- ACREDA)

Purpose of the study: This article attempts to explain the procedures to a self-developed scale on how to identify one’s protective factors and risk factors integral to his or her likelihood of abstinence journey.
Methodology: The 99 items in 5 domains constructed in this scale were incorporated from the insights of library search and one-to-one and group interviews executed with recovering drug addicts in a rehabilitation institution. To establish the scale to be scientifically reliable, the scale was tested its reliability and validity before it was administered for the real population. The validity of this scale was conducted through face validity
with few potential populations to confirm its feasibility while the content validity was done by 2 experts from psychology and drug addiction counselling respectively. Meanwhile, the reliability test of this scale was
undergone through a pilot study upon 132 respondents and some tests in Statistical Package of Social Science Version 21.0 (SPSS) were used to measure the internal consistency of the scale.
Main findings: The consistency of the overall items of this scale was confirmed to be highly reliable with the value of Cronbach’s Alpha, 0.951. The result of the split- half score for the first cluster of the scale recorded
as 0.94 whereas the second cluster was 0.95. The internal consistency also could be glimpsed from its ‘if items deleted’ analysis where the scores are ranged in a small gap of values between 0.929 to 0.934 signifying the
scale was well-constructed in term of its language clarity and balanced distribution of items between dimensions and constructs. Applications of this study: This Abstinence’s Likelihood Scale in Drug
Addiction (ALSDA-ACREDA) instrument is developed by researchers in which the purpose is to measure the likelihood level of drug addicts towards abstinence.
