Objectives:
This contribution looks at the factorial structure of the Therapy Process Questionnaire (TPQ), which is used for daily self-ratings of patients tested by internet-based ambulatory assessment devices.
Methods:
A combined explorative and confirmatory factor analysis of the TPQ. The time-series data were generated by 149 patients treated in an inpatient setting.
Results:
23 out of 42 items included in the explorative version of the TPQ are represented onto five factors, which were identified by a first explorative factor analysis and then validated by a confirmative factor analysis. We report on the psychometric data of the subscales: internal consistency (Cronbach's α), mean of item-intercorrelation, and mean of item discrimination indices.
Conclusion:
The TPQ is useful for a high-frequency and equidistant (daily) assessment of psychotherapeutic change processes.
