Assessing objective countertransference with a computer-delivered Impact Message Inventory (IMI-C).

The circumplex version of the Impact Message Inventory (IMI-C) is one of the few existing diagnostic devices for the assessment of 'objective' (inter-subjective) countertransference. The IMI-C purports to assess eight categories of countertransference reactions along the circumference of the interpersonal circle, conceptualized as blends of the two basic dimensions of affiliation (AFF) and control (CON): dominant (D), hostile-dominant (HD), hostile (H), hostile-submissive (HS), submissive (H), friendly-submissive (FS), friendly (F) and friendly-dominant (FD). As a measure of objective (or 'inter-subjective') countertransference, a crucial test for the IMI-C is its ability to produce scores that are generalizable across different therapists involved with the same patients. In four previous psychometric studies, the 'objectivity' of countertransference reactions was examined with a Dutch paper-and-pencil IMI-C version. In the present study, the generalizability of countertransference reactions across therapists was tested with a computer-delivered IMI-C. Results obtained with the electronic IMI-C format were compared with the findings of the paper-and-pencil version. Similar to the four prior studies, D and HD were the comparatively most generalizable classes of countertransference reactions among the eight categories. Both the AFF and CON main dimensions scores were substantially generalizable across therapists. From different perspectives of analysis, more favorable results were obtained with the computer-delivered IMI-C in comparison to the paper-and-pencil-version for (a) five of the eight countertransference classes (D, HD, F, FS, FD) and also for (b) the AFF main dimension. The computer-based IMI-C appears to be a promising tool for assessing objective countertransference reactions.
