Treatment of social phobia:: randomised trial of internet-delivered cognitive-behavioural therapy with telephone support

Background Although effective therapies for social phobia exist, many individuals refrain from seeking treatment owing to the embarrassment associated with help-seeking. Internet-based cognitive-behavioural self-help can be an alternative, but adherence is a problem. Aims To evaluate a 9-week programme of internet-based therapy designed to increase treatment adherence by the addition of short weekly telephone calls, nine in all, with a total duration of 95 min. Method In a randomised controlled trial the effects of internet-based cognitive-behavioural therapy in the treatment group (n=29) were compared with a waiting-list control group (n=28). Results Compared with the control group the treated participants experienced greater reductions on measures of general and social anxiety, avoidance and depression. Adherence to treatment was high, with 93% finishing the complete treatment package. One year later all improvements were maintained. Conclusions This study provides evidence to support the use of internet-based treatment supplemented by short, weekly telephone calls. Declaration of interest None.
