Validation of the genital herpes treatment satisfaction questionnaire (GHerpTSQ) in status and change versions.

A new measure of treatment satisfaction (GHerpTSQ) for recurrent genital herpes simplex virus (HSV) was validated and used to evaluate two therapeutic strategies widely used for the management of HSV: episodic treatment, where individual herpes outbreaks are treated as they arise; suppressive therapy, where treatment is taken daily to prevent HSV outbreaks. Satisfaction with treatment is important since daily dosing with suppressive therapy is necessary in the absence of symptoms. A 12-item questionnaire was designed using a modified form of the Diabetes treatment satisfaction questionnaire (DTSQ). The psychometric properties of the GHerpTSQ were evaluated within a sample of 125 Canadians with a history of HSV (type 1, 2) infection participating in a 48 week randomised cross-over trial. Factor analysis suggested that the items can be analysed as two separate subscales corresponding to Control/effectiveness, and Convenience/lifestyle; the single item concerning side effects was retained for separate analysis. Forced one-factor analysis showed that the two subscales can be combined to obtain a total score relating to overall treatment satisfaction. The GHerpTSQ has good internal reliability, clear structure with little overlap of subscales and evidence of good sensitivity to changes in treatment.
