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.
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.
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).
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.
人们担心,接受认知康复(CR)的精神分裂症患者对认知缺陷的认识可能会削弱其动机、参与度和CR效果。因此,我们在一个有效的CR项目中,研究了认知缺陷的主观意识与动机和认知学习各方面之间的关系。
对完成30节CR课程的精神分裂症/分裂情感性障碍患者(N = 67)在治疗开始和结束时进行认知表现、自我报告的认知困难、内在动机以及对认知训练任务的感知能力评估。
在横断面测量或治疗前后差异分数测量中,我们发现实际认知功能与感知认知功能之间没有关系。在治疗开始和结束时,对认知问题的更高认识与对认知任务的更低感知能力相关(p值<0.05)。认知问题意识与治疗结束时治疗感知价值之间的显著关系完全由感知能力介导。虽然更高的感知能力与更短的治疗完成时间相关(p = 0.0025),但与认知变化相关的是治疗结束时测量的内在动机(p = 0.02)。
虽然认知问题意识可能不是CR期间认知改善的先决条件,但它可能会影响参与度,以及通过其对感知能力的影响来影响人们对治疗的重视程度。结果还强调了内在动机对于进行认知学习活动的重要性,因为它与认知收获有关。需要进一步研究以了解如何在CR环境中最好地评估和处理对认知能力的认识。
