ABSTRACT
Compared a suicide-completion group to a psychiatric control sample on the 13 traditional MMPI scales, three experimental item pools, and eight profile patterns earlier described as indicative of suicidal tendencies (N = 84). Also compared the frequencies with which the groups endorsed each of the 566 MMPI items. The number of resulting significant differences was less than chance. The results argue against the use of the MMPI to predict suicide at this time.

Administered the 1973 revision of the Henmon-Nelson and the WAIS to 100 psychiatric patients. The correlation of Henmon-Nelson raw scores with WAIS Full Scale scaled score was .83, which compared favorably with correlations run between several other short IQ tests and the WAIS in similar samples drawn from the same setting in earlier studies. However, the Henmon-Nelson did not appear able to estimate the WAIS IQs of low-intelligence Ss or aged persons with consistent accuracy. The validities of short IQ tests and current practices in the selection of WAIS surrogates were discussed.
