The Influence of Psychiatric Symptoms and Cognitive Abilities on Competence-Related Abilities

Ryba, NancyL., Zapf, PatriciaA.·2011·International Journal of Forensic Mental Health

Abstract

This study evaluated the influence of psychiatric symptoms (psychoticism, withdrawal, depression, hostility) and cognitive abilities (executive functioning, working memory, attention, processing speed) on competence-related abilities (understanding, reasoning, appreciation). Seventy-seven male forensic patients were administered the MacCAT-CA, the BPRS, and several cognitive measures. Results revealed that, when considered as a group, the cognitive abilities accounted for more variance in the scores for all three competence-related abilities than did the psychiatric symptoms although there was an additive effect when these groups of variables were considered collectively. Both the psychiatric symptoms and cognitive abilities accounted for a substantial portion of the variance in understanding and reasoning scores, but less so for appreciation. Psychoticism and attention were important factors across all aspects of competence, while working memory was associated with understanding and reasoning, but not appreciation. The presence of symptoms of psychosis had a moderating effect on all four cognitive variables with regard to reasoning, but not understanding or appreciation. The knowledge gained from these results can be used by practitioners to help improve the consistency and accuracy of competency evaluations.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Executive functioning may be a potentially useful target for treatment planning for patients who lack capacity.

    “This may suggest that executive functioning is a potentially useful target for treatment planning for patients who lack capacity, although some authors have challenged this approach (Ryba & Zapf, 2011).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
