Different therapies have different theoretical backgrounds which makes their comparison
difficult. Process research seeks to understand what the common mechanisms are at work
which contribute to successful outcome. The current study sought to compare the content of
two therapies (Cognitive Behaviour Therapy and Interpersonal Therapy) in the treatment of
depression and measure any changes that participants reported.
Taped therapy sessions of IPT and CBT were transcribed and a coding scheme measuring
content of therapy was developed. Participants’ accounts of therapeutic change were
recorded between the two models of therapy across three time periods using a mixed
design. The times periods were divided into: beginning, middle and end of therapy.
Quantitative content analysis was used to measure frequency of occurrence of categories in
therapy. Qualitative Content Analysis was used to compliment quantitative findings and to
compare participants' accounts of change between the beginning and end of therapy.
The results indicated that differences in content reflected the theoretical background of both
therapies. The categories: affect expression, task activation and review, behavioural change
and cognitive change, solution generation, discussion of the model, homework and assumptions occurred significantly more in CBT compared to IPT. All other differences
between the models were not significant.
Differences in content of therapy occurred between the beginning, middle and end of
therapy. There was a reduction in symptoms of depression for participants in both groups as
measured by the BDI but this reduction was not significant.
The discussion related the findings to the current literature and presented ideas for future
