Tourette's syndrome (TS) is a neurodevelopmental disorder linked with frontostriatal dysfunction. Previous work has shown some evidence of mild performance deficits on a range of different tasks that involve inhibitory processes. The present study evaluated this in adult participants with uncomplicated TS. Interference control was measured using the Stroop and flanker tasks and a Stroop-flanker task that combined the inhibitory demands of both. Motor inhibition was measured using a letter continuous performance test (CPT) task and word CPT tasks that manipulated the inhibitory demands using compatible and incompatible words. The TS group was found to be slower than the control group on most measures, but showed differential slowing under conditions with enhanced inhibitory demands on the combined Stroop-flanker and the incompatible CPT tasks. The findings suggest that TS-alone is linked to mild impairments in aspects of inhibitory function, and that these can be detected by relatively powerful inhibitory manipulations. A range of different types of inhibitory tasks may be sensitive to TS-alone, and this may depend on both the type of inhibition and the strength of the inhibitory manipulation.

Despite an emerging evidence base for the efficacy of supported computerized cognitive behavioural therapy (eCBT), uptake in services has been slow. Therapists’ beliefs about eCBT may constitute a barrier to offering eCBT to clients, but little research has investigated this topic. The aim of this study was to investigate therapist attitudes towards eCBT in one inner-city Improving Access to Psychological Therapies (IAPT) service using a survey design. Data were analysed using descriptive statistics. Thirty-three therapists took part in the study. Although 97% of participants reported that they knew ‘what eCBT involves’, and 62% reported that they were ‘confident to offer eCBT to clients’, only 10% endorsed that ‘there is a strong evidence-base to support the use of eCBT’. Two-thirds of the sample believed that eCBT ‘could be effective for mild and moderate mental health difficulties’, but most participants believed that eCBT would perform ‘worse’ or ‘much worse’ than face-to-face interventions for a range of disorders. Barriers to offering eCBT related predominantly to assumptions about client expectations of therapy, and perceived lack of a therapeutic relationship. Participants identified the provision of training on eCBT for those recommending treatment options to clients as a potential solution. Results from this study highlight therapists’ attitudes to eCBT that might contribute to low uptake rates of eCBT. Particularly, misperceptions about the evidence base for eCBT may be prevalent. Appropriate training and ongoing supervision for therapists are considered as interventions that may increase acceptance of eCBT as a valid treatment option.

TS-alone is linked to a mixed pattern of preserved and impaired performance on social cognition measures, and further work is needed to determine the contributions of social and/or executive contributions to everyday functioning.

Tourette's syndrome (TS) is predominantly a childhood disorder, with many of those who meet diagnostic criteria in childhood experiencing a remission of symptoms in adulthood. This indicates that the influence of TS on cognitive and emotional processing can best be understood by examining performance in both adults and children with TS. The present study examined emotional processing using a battery of face and prosody tasks with increasing levels of difficulty (same-different emotion discrimination, emotion naming, and emotion naming with conflict for prosody only). Experiment 1 compared the performance of children with TS-alone (n = 16) or TS+ADHD (n = 15) to healthy matched control children (n = 27). Compared to healthy control children, no significant group differences were found for those with TS-alone. Children with TS+ADHD showed subtle impairments on the more difficult emotion processing tasks relative to healthy control children, and differences were more pronounced for anger items (voice emotion naming, p < .05; voice emotion naming with conflict, p < .01). Experiment 2 compared the performance of adults with TS-alone (n = 23) to healthy matched controls (n = 21). No significant group differences were found, other than evidence of subtle impairment in the adults with TS-alone on the most complex task, again particularly for anger items (p < .05). Separate measurement of executive skills detected no evidence of impairment in children or adults with TS and little in the way of correlational evidence linking emotion recognition and executive skills. Implications of the findings for our understanding of emotion processing in TS are discussed.
