Initial clinical intake: The PADDI‐5 is an ideal adolescent friendly interview for performing a mental health and substance use disorder assessment as part of any routine clinical intake specifically designed to address common issues among adolescents.

Juvenile Justice Evaluations: In addition to clinical settings, the PADDI-5 is ideal for conducting a detailed assessment of adolescents processed at juvenile detention centers or juvenile court settings.

Documentation of severity: The DSM‐5 defines severity for both substance use and mental health disorders in terms of the number of positive diagnostic criteria.

Verification of improvement: Reviewing disorders with positive diagnostic findings can determine if the conditions have improved or if recovery can be documented.

Informing Dimensions 1 and 3 of the ASAM Criteria:

Dimension 1: The PADDI‐5 questions on recent use patterns can identify possible withdrawal

Dimension 3: The extensive coverage of mental health conditions provides substantial information
on commonly occurring co‐occurring conditions.

Motivational enhancement: Reviewing PADDI‐5 results with clients may aid in motivational enhancement. Individuals who are presented with the detailed behaviors and symptoms of their conditions may be more likely to accept referral and become engaged in their treatment plans.
