The speeded IQ test items have been generated using the Sandia Matrix Generation Software. The items have been scientifically validated by Matzen and colleagues (2010). Because this is a speeded IQ test, there is a greater emphasis on working memory relative to fluid reasoning (Gf).
Anxiety and Depression Scores
Working Memory Test
The working memory capacity test is an implementation of the Operation Span (Ospan) test – a complex span task – developed by Turner and Engle (1989).
Anxiety and Depression Scales
The validated Depression and Anxiety tests are the PHQ-9 and the GAD-7 developed by Spitzer and colleagues with a grant from Pfizer Inc.
The battery also includes the following self-report scales that have been developed and validated for internal consistency and normality by Dr Mark Ashton Smith (HRP Lab). A technical report can be downloaded here.
