The WISC-R and WRAT as indicators of arithmetic achievement in juvenile delinquents.

The relationship of the WISC-R Arithmetic and WRAT Arithmetic scales to grades was determined for a sample of 8 female and 14 male juvenile delinquents. The WISC-R correlated .538 with grades and .302 with the WRAT, while the WRAT correlated .289 with grades. The WISC-R also correlated .508 with sex (females scoring higher). While WRAT Arithmetic is questioned as an indicator of academic achievement, WISC-R accounts for 29% of grades variance and may be a useful correlate.

MMPI profile predictors for successful and expired open heart surgery patients.

A total of 31 patients (17 females, 14 males) who were scheduled for open heart surgery were administered an MMPI within 1 week prior to surgery. Of the 31 patients, 20 (13 females, 7 males) survived and 11 (4 females and 7 males) did not survive the operation. MMPI scale T-score comparisons were made within sex between survivors and nonsurvivors. Surviving and expired males did not differ on any MMPI scales, while expired females had much higher average scale 1 and 3 elevations than did their surviving counterparts (p less than .05). Subsequent comparisons of expired and surviving female patients with 1-3 profiles revealed that females with 1-3 profiles who expired had a higher average L scale T-score and a lower average scale 6 T-score (p less than .05). Cutting scores established to divide 1-3 female profiles into success and expired groups yielded two results: (1) an L scale T-score of 50 or above identified 100% of the expired females while it generated 40% false positives and no false negatives; and (2) a scale 6 T-score of 57 and below identified 100% of the expired females while it generated no false negatives and no false positives. These results are consistent with previous research and may be used to predict mortality for prospective female open heart surgery patients with implications for psychotherapeutic assistance prior to surgery to increase prospects for success.
