Objective: The Maryland Assessment of Recovery in Serious Mental Illness
(MARS) is a 25-item, 5-point Likert recovery scale that has been validated for use with adult
clients. The present study examined the psychometrics of the MARS in an adolescent
Methods: Adolescents (n = 121, 60% male, 52% Caucasian, 42% African American) were
assessed periodically during residential treatment using MARS, K-SADS-PL diagnostic
interviews, Youth Self Report (YSR), and Personal Well-Being Index (PWI-SC).
Results: T tests (MARS x gender) and one-way ANOVA (MARS x age, race, primary
diagnosis) showed no differences in MARS scores for normative data. Reliability was strong
using test retest (r = .914) and internal consistency (Chronbach’s a = .952). Repeated
measures ANOVAs found significant main effects and interactions; as number of diagnoses
declined from admission (M = 3.13) to discharge (M = 1.70), MARS scores significantly
increased from admission (M = 93.97) to discharge (M = 105.90); as symptom severity (YSR
total Problems) decreased from admission (M = 66.55) to discharge (M = 60.55), MARS
scores increased showing sensitivity to change validity. Construct validity revealed a
moderate correlation with PWI-SC (r =.42).
Conclusion: The present study provides preliminary evidence that the MARS is a
psychometrically sound instrument for use in assessing recovery in adolescents. Several
limitations of the study are discussed in the interest of further research on use of the MARS
with adolescent clients.
