Abstract. Background: The goal of this study was to investigate whether the results of assessments of alexithymia based on a
self-report questionnaire, the Toronto Alexithymia Scale (TAS), correlates with those based on drawing content in the Wartegg
Drawing Completion Test (WZT). It was hypothesized that high alexithymia scores in theTAS are negatively correlated to the
number of human drawings in the WZT. Method: Subjects were 83 patients of the Oulu Deaconess Institute, Oulu, Finland.
Results: The TAS mean score for subjects with no human drawings was 56.0 compared to 45.4 for those with one or more human
drawings (p < .001). Conclusions: The results can be considered encouraging concerning the overall usefulness and validity of
the WZT. It is concluded that efforts to develop a psychometrically valid and reliable method of interpreting the WZT should be
continued.

Mattlar, Lindholm, Haasiosalo, and Vesala (1991) inves-
tigated whether the Wartegg Drawing Completion Test
(WZT), a projective drawing test developed by Ehrig
Wartegg (1939), may be used to detect alexithymia. On
the basis of the definition of alexithymia by Von Rad
(1983), Mattlar et al. hypothesized that alexithymic sub-
jects would favor conformistic, noncreative solutions in
their drawings and prefer to draw inanimate objects,
while nonalexithymic subjects would favor human or an-
imal drawings. In Mattlar’s study, the interrater agree-
ment between assessments of alexithymia based on War-
tegg drawings was as high as 0.77 for four independent
judges. However, correlations of scores obtained with
the WZT with those of scores obtained using other in-
struments were not studied. Validity studies involving
comparisons between structured personality tests and
projective drawings have generally shown low correla-
tion (Kahill, 1984). While projective drawing tests con-
tinue to enjoy widespread popularity among clinical psy-
chologists, some personality assessment researchers (Li-
lienfeld et al., 2000) have suggested that the use of
projective drawings should be discontinued due to their
lack of reliability and validity.
In Wartegg’s test, the respondent draws eight draw-
ings, deciding freely the topic of each drawing, while in
other projective drawing tests the topic of the drawing,
such as a tree or a person, is given by the tester. Because
of the freedom of choice in the WZT, qualitative aspects
of the drawings are less important in the interpretation of
Wartegg drawings than in the other tests. Very few valid-
ity studies exist for the WZT. The existing interpretation
methods devised for the WZT by Wartegg (1939), Crisi
(1998), and Gardziella (1985) are based on clinical ex-
perience and have not been empirically validated. Roi-
vainen (1997) found a weak correlation between extra-
version as measured by Cattell PF10 (Factors A and E)
and the total number of human drawings in the WZT.
Tamminen and Lindeman (2000) failed to find a signifi-
cant correlation between Wartegg drawings and a per-
sonality profile based on Jackson’s Personality Research
Form (1997).
The purpose of this study was to investigate whether
alexithymia scores based on a psychometrically valid
and reliable self-report questionnaire, the Toronto Alex-
ithymia Scale (TAS; Bagby et al., 1986), correlate with
those obtained based on drawing content in the WZT.
Hypothesis
We hypothesized that high scores in the TAS would be
negatively correlated to the number of human drawings
in the WZT.
