What type of instrument is the POSIT?

The POSIT, or Problem Oriented Screening Instrument for Teenagers, is classified as a self-administered questionnaire. This tool is specifically designed for adolescents to evaluate their substance use and related problems. By allowing individuals to answer questions on their own, the POSIT empowers them to express their thoughts and experiences in a comfortable setting, often leading to more honest and accurate results.

Self-administered questionnaires are valuable in counseling and assessment because they can provide insights into the individual's experiences and behaviors without the potential biases or influences that might arise in an interview or observational setting. Additionally, this format allows for easier data collection and analysis compared to other methods like laboratory tests, which measure physiological criteria rather than self-reported behaviors or feelings.
