Indices of Change: Analysing the Indexical Properties of Data from Psychotherapy Case Work to Discern Patterns of Therapeutic Change Over Time

With reference to semiotic theory, a form of data analysis is proposed that explicitly unpacks the indexical properties of data from psychotherapy case studies. The approach is observed to happen within the therapeutic hour as a co-production between the client and their therapist. Thus analysing the data in this way seeks to address two common charges against traditional research into psychotherapy processes: that it fails to capture the true value of the therapy and lacks the sensitivity to measure outcomes. Two case vignettes will demonstrate the utility of this approach in lived context, with meaning emerging as therapy continues.
