Background:
Schizophrenia is characterised by pervasive cognitive deficits that significantly impair daily functioning and quality of life. Pharmacological treatments have limited efficacy in addressing these deficits, highlighting the need for adjunctive interventions like computerised cognitive training (CCT).
Aims:
This study aimed to evaluate the effects of a 30-session CCT programme on mental well-being and cognitive performance in individuals with schizophrenia. Additionally, it assessed the usability and acceptability of CCT in this population.
Methods:
A double-blind, randomised clinical trial was conducted with 54 participants assigned to intervention and control groups. Cognitive and mental health outcomes were assessed using validated tools such as the Depression Anxiety Stress Scale 21, the Warwick-Edinburgh Mental Wellbeing Scale and the Cambridge Neuropsychological Test Automated Battery. Usability was measured with the System Usability Scale (SUS). Assessments were conducted at baseline, post-intervention and 3 months post-follow-up.
Results:
The CCT intervention significantly improved mental well-being, reduced stress and enhanced working memory (paired associate learning, spatial working memory and spatial span) compared with controls. However, no significant effects were observed for anxiety, depression or executive function. Usability scores were high (SUS=83.51), and compliance rates were strong (92.7%), indicating favourable participant engagement.
Conclusion:
CCT demonstrated potential as an adjunctive treatment for schizophrenia, with significant improvements in targeted cognitive and mental health domains. The high usability and compliance rates support its feasibility for broader implementation. Further research is needed to optimise protocols and explore long-term benefits. CCT offers a promising approach to addressing mental health and cognitive challenges in schizophrenia, particularly for stress and working memory. Its usability and acceptability suggest it could be seamlessly integrated into clinical practice.

Negative Symptoms
Negative symptoms of schizophrenia manifest as deficits in normal emotional and behavioral functioning, profoundly impacting daily life. Individuals with schizophrenia often display a flat affect, characterized by a near-total absence of emotional expression,...
