Alexithymia. The development of a valid and reliable projective measure (the objectively scored Archetypal9 Test).

The aim of this study was to examine whether the Archetypal9 Test (AT9) could meet the need for a valid and reliable test with which to measure the alexithymic trait cluster. Participants in this study included 61 patients drawn from pain clinics in Montreal (Royal Victoria Hospital) and Detroit (Henry Ford Hospital) and 30 patients undergoing minor surgery at the Royal Victoria Hospital in Montreal. All 91 subjects took both the AT9 Test and the Clarke Vocabulary Scale. The results of the attempts at validation reveal that the objectively scored AT9 Test (SAT9) is a highly internally consistent instrument, that it has demonstrated construct validity, and that it can significantly discriminate between patient groups (pain patients and medical patients). The SAT9 is positively related to age, inversely related to occupational level, and uncorrelated with IQ (as measured by the Clarke Vocabulary Scale). The authors concluded that thus far, the SAT9 has proven to be a valid instrument which can be used to measure a central feature of alexithymia.
