Summary
The Turkish Alcohol, Smoking, and Substance Involvement Screening Test (ASSIST) demonstrated strong validity and reliability. This validated screening tool can effectively identify substance use disorders in clinical settings.
Area of Science:
- Psychiatry
- Addiction Medicine
- Psychometrics
Background:
- Substance use disorders pose a significant global health burden, contributing to mortality and morbidity.
- Preventable diseases linked to alcohol, smoking, and substance use are among the top ten causes of death.
- Effective screening tools are crucial for early identification and intervention.
Purpose of the Study:
- To evaluate the Turkish validity and reliability of the Alcohol, Smoking, and Substance Involvement Screening Test (ASSIST) v3.1.
- To assess the correlation of ASSIST scores with established measures of nicotine, alcohol, and drug use.
- To determine the suitability of ASSIST for screening in Turkish psychiatric settings.
Main Methods:
- The study involved two independent sample groups (n=339) interviewed by clinicians.
- The Alcohol, Smoking, and Substance Involvement Screening Test (ASSIST) was administered.
- Correlations were examined using the Fagerstrom Nicotine Dependence Test (FNDT), Alcohol Use Disorder Identification Test (AUDIT), and Drug Use Disorder Identification Test (DUDIT).
- Internal consistency (Cronbach's alpha) and factor structure (Exploratory Factor Analysis, KMO, Bartlett's Test) were analyzed.
Main Results:
- High internal consistency was found for ASSIST (Cronbach's alpha: 0.70–0.98).
- Exploratory factor analysis supported a single-factor structure for most items, with specific groupings for sedatives/hallucinogens.
- Significant correlations were observed between ASSIST scores and FNDT, AUDIT, and DUDIT scores, confirming construct validity.
Conclusions:
- The Turkish version of the Alcohol, Smoking, and Substance Involvement Screening Test (ASSIST) v3.1 is a valid and reliable instrument.
- ASSIST is suitable for screening cigarette, alcohol, and substance use/abuse in Turkish psychiatric and counseling centers.
- Further research in diverse populations can enhance understanding of ASSIST's effectiveness in clinical practice.

01:22Self-Report Tests of Personality
Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.
01:29Reliability and Validity
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.
02:05Self-Presentation: Self-Monitoring and Self-Handicapping
People can go to great lengths to protect their self-image and present themselves in ways that they want others to see them. Sociologist Erving Goffman presented the idea that a person is like an actor on a stage. Calling his theory dramaturgy, Goffman believed that we use “impression management” to present ourselves to others as we hope to be perceived. Each situation is a new scene, and individuals perform different roles depending on who is present (Goffman, 1959). Think about the way you...
