BACKGROUND: The concurrent validity of subclinical ratings for psychiatric symptoms can help refine symptom definitions and threshold criteria. However, virtually no research has examined subclinical ratings for DSM-IV symptoms in psychiatric diagnostic interviews. This study examined the frequency, reliability, and concurrent validity of subclinical ratings for 11 symptoms of alcohol use disorders among adolescents. METHODS: Subjects were 239 male and 164 female adolescents ages 14 to 18 recruited from treatment and community sources. Symptoms and diagnoses were made with an adapted version of the Structured Clinical Interview for the DSM-IV. RESULTS: Subclinical ratings showed acceptable to high interrater reliability. The proportion of subclinical ratings tended to decrease with increasing levels of alcohol problems. For 10 of the 11 symptoms, subjects with subclinical ratings were distinguished from those with absent and/or those with present ratings. Subjects with subclinical ratings were often distinct from those with present ratings but less often distinct from those with absent ratings. CONCLUSIONS: For most of the DSM-IV alcohol use disorder symptoms, subclinical ratings appear to be reliable and valid and provide information beyond dichotomous symptom classifications for adolescents. Threshold criteria appear to be appropriate in many cases, but boundaries between absent and subclinical ratings are "fuzzy." Practical and research implications are discussed.
