Abstract

People with severe mental illness (SMI) frequently experience cognitive difficulties, negatively impacting quality of life. This study investigates two cognitive interventions, cognitive remediation combined with transcranial direct-current stimulation, and focuses on the association between subjective, objective and observer-rated cognitive functioning. Literature suggests that the results of these three different measures do not consistently correlate with each other. This study explores these relationships and how to use these data types to evaluate cognitive interventions. The sample comprised 29 service users with SMI and cognitive impairments. The participants were randomised to CR + active tDCS or CR + sham tDCS. Training sessions were done twice weekly for 16 weeks. A neuropsychological test battery, the CFQ and the NOSCA were taken four times. Correlations were computed between the different types of cognitive functioning. The results showed no consistent pattern between the outcome measures; we cannot conclude that there are linear relationships between the data types. This either signifies a lack of insight into cognition or a conceptual distinction between subjective and objective and observer-rated cognitive functioning. Overall, the results show the uncertain nature of the relationship between the three cognitive measures. In clinical practice, it is important to explore all three measures, as this will provide a more complete image of an individual’s cognitive functioning.
