Although we have evidence that cognitive remediation is effective we have not yet persuaded service providers to adopt it into their treatment packages. This paper outlines the cognitive remediation literature that has sculpted the field. It is not a systematic review but an expert’s opinion of the research required to influence treatment decisions so that our patients are offered the best options for fulfilling their goals. The gaps in research include defining the benefits in terms of those that service providers and service users value. These include costs against the effects of treatment and fulfilling individual recovery goals. These are not rocket science and only require extra and least burdensome (on participants) measures to be added to studies. We also need to use data we already possess to carry out further analyses to indicate how different therapies work and to compare across studies in large individual participant level databases.
