In order to provide clinicians with a more thorough understanding of child's performance on Block Design, Digit Span and Cancellation, seven process scores are included in the Wechsler Intelligence Scale for Children-Four edition (WISC-IV): Block Design No Time Bonus (BDN), Digit Span Forward (DSF), Digit Span Backward (DSB), Longest Digit Span Forward (LDSF), and Longest Digit Span Backward (LDSB). For relevance of prognostic statements, it is essential to rely on test scores that are stable across time. The goal of this study was to explore the long-term stability of the WISC-IV process scores (BDN, DSF, DSB, LDSF, and LDSB). The sample consisted of 277 nonclinical French-speaking Swiss children aged between 7 and 12 years (at first testing: mean age = 8.87 and SD = 0.82; at second testing: mean age=10.64 and SD = 1.11). The WISC-IV were administered twice in an average test-retest interval of 1.77 years (SD = 0.56).
