This research is a pre-registered individual-level metaanalysis to identify factors contributing to cognitive training efficacy for anxiety and depression symptoms. Machine learning methods, alongside traditional statistical approaches, were employed to analyze 22 datasets with 1544 participants who underwent working memory training, attention bias modification, interpretation bias modification, or inhibitory control training. Baseline depression and anxiety symptoms were found to be the most influential factor, with individuals with more severe symptoms showing the greatest improvement. The number of training sessions was also important, with more sessions yielding greater benefits. Cognitive trainings were associated with higher predicted improvement than control conditions, with attention and interpretation bias modification showing the most promise. Despite the limitations of heterogeneous datasets, this investigation highlights the value of large-scale comprehensive analyses in guiding the development of personalized training interventions. |  |  |\n| Interventions targeting the cognitive mechanisms underlying anxiety and depressive symptoms have gained significant research interest in recent decades due to the high prevalence of these symptoms and the potential of online and remote treatment delivery.\u003Cbr>Computerized cognitive interventions target the neurobiological mechanisms underlying cognitive and emotional domains by means of a demanding and engaging task that is repeatedly performed on a technological device1,2. Studies that have tested the efficacy of different cognitive training interventions in alleviating maladaptive symptoms of anxiety and depression have yielded contradictory outcomes (for a more thorough review see refs. 3,4).\u003Cbr>Evidence suggests that specific characteristics of computerized cognitive training (such as the number of training sessions5) influence training efficacy. Moreover, some studies indicate that specific types of training methods are more effective in certain situations and/or for specific populations (e.g., greater improvements from attention bias modification for | individuals dealing with generalized anxiety or depression, but lower improvements for those dealing with social anxiety and post-traumatic stress disorder6). Comparing the effectiveness of computerized training techniques, as well asthe effect ofindividual differenceson training efficacy, is highly valuable for several reasons: (a) they can provide guidelines to determine the optimal conditions and characteristics of effective training regimes1; (b) they can advance knowledge on central mechanisms underlying successful training7; and (c) they can promote individually tailored training programs8. Anxiety and depression are the most prevalent mental health disorders globally, imposing a substantial individual and economic burden that exceeds many other conditions9, 10.
