Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
In the first of three studies that aim to the efficacy of psychotherapies focused on the expression of emotion, Pennebaker & Beal's (1986) written disclosure methodology will be applied to an individual psychotherapeutic context. In an extension of the Pennebaker & Beal (1986) paradigm; and in accord with recent theoretical developments (i.e., A to D Emotion Theory; Pennebaker & Chung (In-Press)), Participants allocated to the Treatment group will be encouraged to use emotion labels when expressing their deepest thoughts and feelings with respect to the following topics: Diagnosis (weeks 1 & 6); Treatment/Waiting for Results (weeks 2 & 7); Living in Remission (weeks 3 & 8); Most Distressing/Traumatic Experience (weeks 4 & 5). Participants randomly allocated to the Treatment group will attend 8 x 1 hour, individual sessions.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The Randomisation to control and intervention groups will be handled by administrative personnel at the Royal Adelaide Hospital, to ensure researchers involved in the trials are removed from this process. Given the nature of the study, however, it is not possible to conceal whether or not one receives psychotherapy.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Administrative personnel at the Royal Adelaide Hospital will use the facility available on the Microsoft Excel Program to allocate Participants to the Routine Care Group or the Treatment Group.
Masking / blinding
