“…The ability of the HoNOS to discriminate between consumer groups differentiated on a range of treatment- and service-based indicators has also been used to test its concurrent validity. Several studies have found high total scores on the HoNOS to be associated with diagnoses of drug and alcohol, psychotic and bipolar disorders, high scores on items relating to hallucinations/delusions and social and cognitive problems to be associated with a diagnosis of schizophrenia, high scores on items relating to aggressive behaviour, drinking/drug taking and anxiety to be associated with a diagnosis of mania, and high scores on items relating to suicidal thoughts/behaviours, physical illness and depressed mood to be associated with a diagnosis of depression [ 16 , 20 , 24 , 26 , 37 , 38 ]. Similarly, a number of studies have found that the HoNOS can discriminate between consumers with differing levels of need or disability, as indicated by their current or expected location of treatment – e.g., those receiving standard case management versus those assertive case management [ 39 ], those in residential/nursing home, day patient, outpatient and inpatient settings [ 14 , 15 , 28 ], and those in long-stay settings with low, medium and high expectations of discharge [ 40 ].…”
