With aims to fill this gap, we previously developed a ketamine/esketamine drug liking and craving questionnaire (DLCQ), which primarily considered level of drug liking as a risk factor for potential future misuse or abuse. In adapting this for use with psychedelics, several considerations arose, including the likelihood that the psychedelic experience may be more universally pleasurable, and that desire to use psychedelics again may carry several underlying reasons. Here, we describe the Liability for Abuse of Psychedelics Questionnaire (LAPQ), which provides a framework incorporating 3 domains; substance use history, liking and craving for the drug in question, and subsequent changes in substance use patterns after exposure to the drug.

In this study, 502 university students completed assessments including the Schizotypal Personality Questionnaire-Brief and the Internalized Stigma of Mental Illness scale, alongside measures of repetitive negative thinking (RNT), social phobia, anxiety, and depression.

The most influential feature was the engineered difference between peak active hours, which along with other activity and age features classified all diagnostic groups with 91.5 % accuracy. Results indicated that daily activity levels, especially the variability between peak activity hours, showed potential for improving diagnostic precision in psychiatric settings. Actigraphy, combined with machine learning, offers a promising approach for classifying diagnostic groups among inpatient adolescent populations and engineered maximum and minimum hourly activity features may provide objective markers to improve diagnostic accuracy.
