While treatment aimed at the improvement of social cognition is available for other neuropsychiatric disorders, no such interventions yet exist for NS patients. In this study, the development of the first social cognitive training for NS patients is described and its applicability and feasibility evaluated. Methods: Eleven adult patients with NS participated in this controlled proof-of-principle study. Six patients were included in the treatment group and five in the control group. Neuropsychological testing was performed in both groups at baseline and posttreatment. Social cognition was a primary outcome measure and nonsocial cognition and psychopathology secondary outcome measures. Differences between pre- and posttest were investigated with Wilcoxon signed-rank tests, and a process evaluation was performed to aid interpretation of the results. Results: Both groups were comparable with regard to age, estimated intelligence, and baseline performance. Although no significant differences were found between pre- and posttest scores on primary and secondary outcome measures in either group, a medium–large effect size was found on emotion recognition in the treatment group. Also, the process evaluation demonstrated the feasibility of the training. Conclusion: This first social cognitive training for adult patients with NS has proven to be feasible for this population and showed some encouraging results regarding emotion recognition, although the training protocol could be optimized. Further investigation is required using a randomized controlled design in a larger sample, in order to substantiate the overall effectiveness of the training.
