A script questionnaire and associated checklist developed by Ohlsson, Johnsson & Björk (1992) was used by the author and two professional colleagues to independently assess ten clients of a year-long transactional analysis therapy group conducted by the author. Ratings based on written responses at start of therapy were compared to ratings based on videotape interviews conducted by the author six years after termination of therapy. Moderately high inter-assessor reliability was found but intra-assessor reliability was low for the independent assessors; agreement increased for script components ‘primary injunction from father,’ ‘racket feeling’, ‘escape hatch’, ‘driver from father’ and ‘driver from mother’.
