How does awareness of cognitive impairment impact motivation and treatment outcomes during cognitive remediation for schizophrenia?

ABSTRACT:

Background

There is concern that awareness of cognitive deficit among people with schizophrenia receiving Cognitive Remediation (CR) might undermine motivation, engagement, and CR outcomes. We therefore examined the relationship of subjective awareness of cognitive deficit to aspects of motivation and cognitive learning during an efficacious CR program.

Methods

Individuals with schizophrenia/schizoaffective disorder who completed 30 sessions of CR (N = 67) were evaluated on cognitive performance, self-reported cognitive difficulties, intrinsic motivation and perceived competency for cognitive training tasks at the beginning and end of treatment.

Results

We found no relationship between actual and perceived cognitive functioning when measured cross-sectionally or as difference scores, pre/post treatment. Greater awareness of cognitive problems was associated with lower perceived competency for cognitive tasks at treatment beginning and end-point (p-values < .05). The significant relationship between awareness of cognitive problems and perceived value of the treatment at end-point was fully mediated by perceived competency. While greater perceived competency was associated with shorter time to treatment completion (p = .0025), it was intrinsic motivation measured at end-point that was associated with cognitive change (p = .02).

Discussion

While awareness of cognitive problems may not be a prerequisite for cognitive improvement during CR, it could impact engagement in, and how one values treatment via its effect on perceived competency. Results also highlighted the importance of intrinsic motivation for doing cognitive learning activities, given its relationship to cognitive gain. Further study is needed to understand how best to assess and address awareness of cognitive abilities within the CR setting.

Project description:BackgroundMany bipolar patients (BP) are affected by cognitive impairments and reduced psychosocial function even after complete remission. In the present naturalistic study, we developed a tailored cognitive remediation program (CR) to evaluate the effect on objective and subjective neuropsychological performance, psychosocial functioning and quality of life.MethodsThe CR program used a cognitive training software combined with group sessions to educate cognitive skills. 102 BP were screened by a neuropsychological test battery. Of those, 39 BP showed distinct cognitive impairments and 26 patients of them participated in the CR program for 12 weeks and then were retested. A matched control group consisting of 10 BP was measured at baseline and follow-up after three months (treatment as usual).ResultsWithin the training group, a significant improvement of cognitive performance after CR was observed in working memory (p = .043), problem solving (p = .031) and divided attention (trend, p = .065). The control group did not improve in any test measure. In addition, we detected a significant reduction of sub-depressive symptoms (p = .011) after the CR program. However, there was no change in psychosocial functioning and quality of life. Subjective cognitive complaints were not associated with objective test performance.LimitationsAs we included exclusively BP with objectively assessed neurocognitive deficits, recruitment was difficult and subsequently we had a small sample size and were not able to implement a randomized group design.ConclusionsOur results suggest that BP with objective cognitive impairments could benefit from CR potentially with regard to executive functioning. Furthermore, there is preliminary evidence that CR could have a positive effect on subthreshold residual symptoms. However, to fully identify the possible implications of CR in bipolar disorder, larger randomized-controlled trials are needed in this new field of research.
