“…Once the WAIS-III protocols were scored in the standardized manner, the protocols were then rescored according to the procedures outlined in Axelrod et al (2001) and Pilgrim, Meyers, Bayless, and Whetstone (1999) for the seven-subtest short form of the WAIS-III. Two methods of scoring were chosen to account for the two methods of weighting the seven-subtest short forms.…”

“…Two methods of scoring were chosen to account for the two methods of weighting the seven-subtest short forms. The method advocated by Axelrod et al (2001) prorates the scaled scores obtained from the administration of the WAIS-III to obtain the index and summary IQ scores. This was accomplished by summing the age-scaled scores for the verbal subtests (Information, Similarities, Arithmetic, Digit Span) and multiplying the resulting sum by 6/4.…”

Intellectual functioning remains an important domain of functioning to be measured. To reduce the lengthy administration time, numerous short forms of the WAIS-III have been devised. The present study aimed to compare two methods of applying short forms of the WAIS-III within a clinical population. The results revealed that both item-reduced and selected subtest short forms provide excellent predictions of full administration WAIS-III summary and index scores. The Satz-Mogel short form appeared to provide higher predictive power than the seven-subtest short forms and accounted for a higher number of cases within 6 points of the obtained scores from the full administration. However, the Satz-Mogel short form was inferior to the seven-subtest short forms in terms of the reliability of the index and summary IQ scores. As found in previous research, a trade-off occurs between the predictive power and the reliability of a short form.

Background. Recent clinical investigations showed impaired episodic future thinking (EFT) abilities in multiple sclerosis (MS) patients. On these bases, the aim of the current study was to explore the structural and functional correlates of EFT impairment in nondepressed MS patients. Method. Twenty-one nondepressed MS patients and 20 matched healthy controls were assessed with the adapted Autobiographical Interview (AI), and patients were selected on the bases of an EFT impaired score criterion. The 41 participants underwent a functional magnetic resonance imaging (fMRI) session, distinguishing the construction and elaboration phases of the experimental EFT, and the categorical control tests. Structural images were also acquired. Results. During the EFT fMRI task, increased cerebral activations were observed in patients (relative to healthy controls) within the EFT core network. These neural changes were particularly important during the construction phase of future events and involved mostly the prefrontal region. This was accompanied by an increased neural response mostly in anterior, and also posterior, cerebral regions, in association with the amount of detail produced by patients. In parallel, structural measures corroborated a main positive association between the prefrontal regions' volume and EFT performance. However, no association between the hippocampus and EFT performance was observed in patients, at both structural and functional levels. Conclusion. We have documented significant overlaps between the structural and functional underpinnings of EFT impairment, with a main role of the prefrontal region in its clinical expression in MS patients.

“…It comprised the following functions, general verbal abilities, tested with the Verbal IQ, short form [4] of the WAIS-111 [61], and nonverbal reasoning assessed using the Advanced Progressive Matrices Set 1 [41]. Anterograde memory was examined with the Rey Auditory Verbal Learning Test (RAVLT; [42]), and the Rey-Osterrieth Complex Figure (ROCF; [36,43]).…”

The aims of the present study were (i) to explore autobiographical memory and episodic future thought in multiple sclerosis (MS), using Levine's Autobiographical Interview; (ii) to investigate the influence of the Interview's high retrieval support condition (the specific probe phase) on MS patients' past and future simulations and (iii) to obtain the patients' estimations of their own difficulties, during the test, and in everyday life. To that end, we examined 39 non-depressed relapsing-remitting MS patients and 34 healthy subjects matched for gender, age and education level. The 73 participants underwent an adapted version of the Autobiographical Interview in two conditions: remembering and imagining personal events. The group of patients also underwent an extended neuropsychological baseline, including particularly, anterograde memory and executive functions. The results showed that the MS patients' scores on the baseline were mildly or not impaired. On the contrary, the Autobiographical Interview measure, i.e., the mean number of internal details, for each of the two phases of the test -free recall and specific probe -was significantly lower in simulated past and future events in comparison with the healthy controls. Within each group, autobiographical memory performance was superior to episodic future thought performance. A strong positive correlation was observed between past and future mental simulation scores in both groups.In conclusion, our results showed, for the first time, the co-occurrence of deficit of remembering the past and imagining the future in MS patients. They also showed more difficulty in imagining future events than remembering past events for both patients and normal controls. MS being a neurological condition very frequent in the young adult population, the clinical considerations of our study might be of interest. Indeed, they give rise to new insights on MS patients' daily life difficulties related to impaired mental simulation of personal events despite general abilities, including anterograde memory, only mildly or not impaired.
