This study compares 30\u2010day self\u2010reported service use for homeless individuals (N = 229) randomly recruited from a single urban environment (St Louis, Missouri) with similar data collected from a broad array of service agencies providing homeless, substance abuse and outpatient mental health services across the same environment. Comparisons were made between self\u2010report and agency\u2010based data on shelter use, outpatient mental health service use (case management, psychiatric treatment, group therapy), outpatient substance abuse service use (case management, counselling, group therapy) and drop\u2010in\/day treatment use. Consistently low levels of kappa scores (all under 0.4) and correlation coefficients (only shelter use demonstrated significant agreement) were found. Findings demonstrated that the two methods of collecting service data are generally not concordant at the individual level. Certain demographic characteristics (increased age, being male, non\u2010white ethnicity) and diagnoses (cocaine abuse\/dependence, mania, schizophrenia) were associated with decreased reliability between the two methods of data collection. The two methods of assessment appeared to capture overlapping but not identical information. Each method of assessment has different utility to researchers and providers wishing to assess service use.
