Screening for mental disorders can increase help seeking and directly link individuals with appropriate services. However, there is a need to develop brief, accurate screening instruments for assessing multiple mental disorders. Two-stage hierarchical screening, consisting of brief pre-screening followed by a battery of disorder-specific scales for those who meet diagnostic criteria, may increase the efficiency of screening without sacrificing precision. Four hierarchical methods to rapidly identify individuals who would benefit from comprehensive screening will be presented. These methods were tested using two online community-based adult Australian cohorts (N = 2028). Results indicate that using the Kessler-6 psychological distress scale is an inefficient method of identifying candidates for full screening. However, two decision tree approaches and an item gating approach increased screening efficiency considerably, with a reduction in mean items presented of up to 54% and close to 100% sensitivity. Findings will be discussed in the context of the development of adaptive screening methods using Item Response Theory and similar approaches. Hierarchical screening and other adaptive screening methods show potential for considerable increases in the efficiency of screening for multiple mental disorders.
