On a practitioner's need of further development of Wechsler scales. Adaptive Intelligence Diagnosticum (AID 2).

Wechsler's intelligence test-batteries are still popular yet suffer from psychometric shortcomings and lack a certain content improvement and enlargement. In this paper a new approach will be presented that suits traditional Wechsler-testing. The approach in question is the Adaptive Intelligence Diagnosticum (AID 2; Kubinger & Wurst, 2000). Due to it's "branched testing" design, AID 2 works out to be more economical and in this regard also offers other advantages, such as parallel tests and short forms. AID 2 offers a method of survey for identifying specific developmental disorders or learning disabilities. It includes an optional non-verbal instruction and a schedule for retrograde observation support of behavioral misfits. It also offers discriminative indicators for intellectual neglect vs. intellectual advancement.
