The Rorschach Coping Deficit Index as an Indicator of Neurocognitive Dysfunction

Abstract

Abstract. Despite a conceptual link between the Rorschach Coping Deficit Index (CDI) and a loss of cognitive and functional capacity, no published study has explored whether or how the CDI relates to these characteristics as measured by other neuropsychological test instruments. We examined the relationship between the CDI and neurocognitive abilities of language skills, perceptual organization, memory, and executive functioning separately in adolescent psychiatric inpatients (n = 267), as well as in adults with first episode schizophrenia or severe affective disorder (n = 117), and healthy adults (n = 94). We found a significant link between the CDI and limited cognitive capacity. Impaired comprehension predicted the elevated CDI in adolescents whereas perseveration tendency and impaired delayed memory in adult patients and impaired memory functions in healthy people predicted the elevated CDI. The CDI seems to include neurocognitive aspects, and may reflect persistent deterioration associated with neurocognitive dysfunction.
