This article describes a case study that demonstrates an innovative combination of predominantly behavioural techniques in the treatment of trichotillomania (TTM) preceded by social phobia. Outcomes are reported to 4-year follow-up. A master's qualified cognitive–behavioural nurse therapist administered the course of treatment over 1 year and followed the client for 4 years. A combination of exposure and response prevention, habit reversal and serial photography for TTM urges, exposure for social phobia, cognitive restructuring and problem solving were utilised. These treatments were provided sequentially and concurrently. Pre and posttreatment and repeated outcome measures were applied in three domains. The client received a total of 23 treatment sessions over 1 year and follow-up over 4 years. During treatment, discharge and follow-up improved outcomes in TTM and social phobia were achieved and maintained at 4 years. Benefits accrued beyond the presenting conditions to have a major positive impact on the client's life. Theoretical implications for the classification of TTM are discussed.
