Public title
Enhancing cognitive-behavioural therapy for recurrent headache by integrating into it a new approach to the management of headache triggers (Learning to Cope with Triggers)
Scientific title
Evaluating the impact of incorporating a learning to cope with triggers compared to avoidance of triggers as part of cognitive behavioural therapy for tension-type headache and migraine sufferers by measuring the primary outcomes of (a) daily headache activity; (b) headache medication usage: (c) the presence of triggers and (d) the impact of headache on daily living.

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Intervention 1: 12 weekly sessions of cognitive behavioural therapy, relaxation therapy and exposure as an opportunity to practice coping skills or when not possible the use of avoidance of triggers. Each 50 minute session will be administered in an individual format by a registered psychologist.

Intervention 2: 12 weekly sessions of cognitive behavioural therapy, relaxation techniques including components on the avoidance of triggers. Each 50 minute session will be administered in an individual format by a registered psychologist.

Comparator / control treatment
Wait list Control no treatment. The wait list control group will be offered treatment following the post assessment period (12 weeks of treatment and 4 week followup). The wait list control group will be offered either treatment 1 (learning to cope with triggers) or treatment 2 (Avoidance of triggers). Treatment type will be according to the participants preference.

Outcomes
Primary outcome [1] 291897 0
Self-monitoring of daily headache activity using a headache diary
Timepoint [1] 291897 0
The diaries will be assessed at baseline (for 4 weeks prior to commencement of treatment), throughout treatment, immediately post treatment (for 4 weeks), four and 12 month follow-up (for 4 weeks).
“Throughout treatment” means monitoring this on a daily basis over the 12 weeks of treatment.

Statistical methods / analysis
The design of the proposed study will focus on the interaction test of a mixed factorial design. Data will be tested for assumptions underlying both univariate and multivariate parametric analysis.
The power analysis is based primarily on the effect sizes generated in previous clinical trials of f = 0.33 to 0.42. Based on previous results an effect size of f =.25 (commonly accepted convention for a medium effect) can be confidently predicted. Power analysis using a G-Power software package indicates that for a three-group mixed factorial design with 40 participants per group and alpha = .05, moderate effects (f =.25) would be reliably identified with power .93 and a large effect (f = 0.4)would have an almost certain probability of being reliably identified.
Any missing data will be considered on an ‘intention-to-treat’ basis and fully analysed for the presence of MAR, MCAR, and NMAR patterns. In addition to exploratory descriptive and correlational analyses, group by phase factorial ANOVAs using a Linear Mixed Models approach will be the main method of analysis for assessing treatment outcome. These will be supplemented by analyses of simple main effects and trend analysis (ie. analysis of orthogonal polynomials) to examine the pattern of change over time for the experimental group. A linear mixed modelling approach has been chosen in order to permit: flexible structuring of the repeated covariance associated with the phase effect; more options for dealing with missing values; the analysis of individual change via growth curves; and options for analysing multi-level models, should they be theoretically or clinically relevant. For all inferential tests, measure of effect size (ie. either d or eta 2) will be calculated, including confidence intervals around those measures. A range of clinical significance measures will also be considered. Finally, regression analyses will be used to examine predictors of response to treatment, and the approach of Preacher and Hayes (2008) to moderation analysis will be used to examine the client-treatment matching hypotheses.
