Psychometric Evaluation of the Symptoms and Functioning Severity Scale (SFSS) Short Forms with Out-of-Home Care Youth.

BACKGROUND There is a need for brief progress monitoring measures of behavioral and emotional symptoms for youth in out-of-home care. The Symptoms and Functioning Severity Scale (SFSS; Bickman et al., 2010) is one measure that has clinician and youth short forms (SFSS-SFs); however, the psychometric soundness of the SFSS-SFs with youth in out-of-home care has yet to be examined. OBJECTIVE The objective was to determine if the psychometric characteristics of the clinician and youth SFSS-SFs are viable for use in out-of-home care programs. METHODS The participants included 143 youth receiving residential treatment and 52 direct care residential staff. The current study assessed internal consistency and alternate forms reliability for SFSS-SFs for youth in a residential care setting. Further, a binary classification test was completed to determine if the SFSS-SFs similarly classified youth as the SFSS full version for low- and elevated-severity. RESULTS The internal consistency for the clinician and youth SFSS-SFs was adequate (α = .75 to .82) as was the parallel forms reliability (r = .85 to .97). The sensitivity (0.80 to 0.95), specificity (0.88 to 0.97), and overall accuracy (0.89 to 0.93) for differentiating low and elevated symptom severity was acceptable. CONCLUSIONS The clinician and youth SFSS-SFs have acceptable psychometrics and may be beneficial for progress monitoring and additional research should clarify their potential for progress monitoring of youth in out-of-home programs.
