Background: Clock-drawing tests are popular components of dementia screens but no single scoring system has been universally accepted. We sought to identify an optimal subset of clock errors for dementia screening and compare them with three other systems representative of the existing wide variations in approach (Shulman, Mendez, Wolf-Klein), as well as with the CDT system used in the Mini-Cog, which combines clock drawing with delayed recall.

Methods: The clock drawings of an ethnolinguistically and educationally diverse sample (N = 536) were analyzed for the association of 24 different errors with the presence and severity of dementia defined by independent research criteria.

The psychological reactions and coping strategies used in response to a behavioral contingency (confinement in a magnetic resonance imaging [MRI] scanner) during a biological challenge (sodium lactate infusion) were systematically studied in 13 subjects with panic disorder (PD) and 11 control subjects using the Claustrophobia Questionnaire (CQ) and the Revised Ways of Coping Checklist (RWCCL). All participants were able to successfully complete the experimental procedure. Findings suggest between-group coping strategy differences in response to general stressors, but relative convergence of coping strategies in response to the experimental procedure, with relatively greater emphasis on problem-focused coping approaches.
