Measuring and understanding "quality of life" among emerging adults in a substance use program.

Objective: This work focuses on understanding quality of life and evaluating a brief quality of life measure in an outpatient emerging adult (17-25 years of age) substance use program.

Method: Mixed methods were used including: (a) psychometric evaluation of the adapted MyLifeTracker (MLT) based on assessments completed four times throughout treatment ( = 100) and (b) qualitative interviews with 12 emerging adults in the program. The study was codesigned, cofacilitated, and cointerpreted with emerging adults with lived experience.
