Computer-Assisted Cognitive Training for Patients with Severe Mental Illness: a Retrospective Study

East Asian Arch Psychiatry. 2021 Sep;31(3):71-80. doi: 10.12809/eaap2097.


OBJECTIVES: To investigate the effectiveness of eight 45-minute sessions of computer-assisted cognitive training programme (CCTP) on improving the cognitive and functional performance of patients with Severe Mental Illness (SMI).

METHODS: Medical records of 16 women and 13 men aged 26 to 62 (mean, 46.34) years who participated a CCTP were reviewed. The CCTP lasted a total of 6 hours in eight sessions over 8 weeks and comprised a series of mobile applications customised to patients’ specific impaired cognitive domains. Pre- and post-test performance of cognition and functioning were assessed using the Montreal Cognitive Assessment Hong Kong version (HK-MoCA) and the Brief Assessment of Prospective Memory (BAPM), respectively.

RESULTS: After the CCTP, the mean HK-MoCA score increased significantly (23.62 ± 5.34 vs 25.48 ± 3.75, d = 0.403, p = 0.001), with a significant increase in delayed recall (3.14 ± 1.75 vs 3.93 ± 1.44, d = 0.493, p = 0.003), and the mean BAPM score decreased significantly (1.44 ± 0.47 vs 1.26 ± 0.23, d = 0.486, p = 0.012). The improvement was greater in participants with primary-level education than in participants with secondary- or tertiary-level education in terms of the HK-MoCA score (3.83 ± 3.06 vs 1.35 ± 2.12, d = 0.942, p = 0.046) and the BAPM scores (-0.49 ± 0.43 vs -0.10 ± 0.29, d = 1.063, p = 0.035).

CONCLUSION: Our shortened CCTP effectively enhanced the cognitive performance and daily functioning of patients with SMI. Verbal episodic memory showed the most improvement. The improvement was greater in those with primary-level education than in those with secondary- or tertiary-level education.
