Types and mechanisms of idiographic change during guided self-help for anxiety.

OBJECTIVES

To compare idiographic change during two formats of guided self-help (GSH); cognitive-behavioural therapy guided self-help (CBT-GSH) and cognitive analytic therapy guided self-help (CAT-GSH).

DESIGN

Qualitative inductive thematic analysis.

METHODS

Semi-structured interviews with N = 17 participants with a reliable change outcome on the GAD-7 after completing GSH for anxiety. Changes were categorised and themes extracted.

RESULTS

No differences between CAT-GSH and CBT-GSH were found regarding types of change reported. The five overarching themes found were personal qualities of success, enlightenment through understanding, specific tools and techniques, changes to relationships and tailoring support. Four themes maximally differentiated between the two different types of GSH; CAT-GSH enabled relational insight and change whilst CBT-GSH enabled better understanding of anxiety, new coping techniques and supportive relationships.

CONCLUSIONS

Both common and model-specific factors contribute to patient change during GSH. Whilst all forms of GSH are grounded in the psychoeducational approach, separate theoretical foundations and associated methods facilitate different types of ideographic change.
