Reliable Change Indices and Regression-Based Measures for the Rey-Osterreith Complex Figure Test in Partial Epilepsy Patients

Abstract

The Rey-Osterreith Complex Figure (ROCF) is commonly used in evaluations of patients undergoing epilepsy surgery. We assessed test-retest performance on ROCF in 30 partial epilepsy patients (mean interval = 33.7 months) to derive reliable change indices (RCIs) and regression-based measures for change. ROCF reproductions were rescored by three raters (IRR Copy: 0.963; Delayed Recall: 0.986). The derived adjusted RC (90% CI) cutoff values for the ROCF Copy were (<or=-6.5, >or=8.4) and were (<or=-6.8, >or=10.0) for the Delayed Recall. Results from regression-based analyses were negative, using age, education, seizure duration, and age of onset, whereas a baseline score was a significant predictor of a follow-up score. The results provide a means to evaluate long-term outcome in epilepsy patients using the ROCF.

“…Determination of reliable change cutoff values was established by published criterion derived for patients with medication-refractory epilepsy. 51 , 53 Adhering to common neuropsychology practice, reliable change is inferred for any individual that obtains a pre/postsurgery difference score that meets or exceeds established RCI 90% confidence interval (CI) score for each test/measure. 51 , 53 Scores that exceed a 90% CI indicate that the change in test in pre/postoperative test scores is reliable and not due to measurement error.…”

Wada asymmetry in patients with drug‐resistant mesial temporal lobe epilepsy: Implications for postoperative neuropsychological outcomes

“…Contrary to prior research among patients undergoing temporal lobectomies, we found no decline in semantic fluency regardless of dominant or nondominant resection using the selective procedures utilized for these patients. This finding likely reflects sparing of semantic networks within the anterior and lateral neocortex in selective AH via ITG procedure, as compared to more traditional ATL procedures . Within the group of patients with No‐WMA, there was a decline in immediate and delayed verbal recall compared to their counterparts with WMA.…”

“…34 The ROCFT 90% CI with practice was À7 or +10 points. 36 Reliable change scores were calculated for neuropsychological measures that were observed to significantly change postoperatively for each participant. Table 5 summarizes the proportion of participants in each group exceeding the 90% CI RCI score for a reliable change in neuropsychological score following surgery.…”

Memory outcome following left anterior temporal lobectomy in patients with a failed Wada test

“…A p-value of less than 0.05 was considered significant. In order to verify whether individual patients experienced a statistically significant deterioration in their post-ATL cognitive and memory scores, we used published reliable change indices (RCIs) for all the cognitive and memory tests [30][31][32]. Changes in scores that fell beyond the 90% RCI range were considered as those that occurred beyond test-retest variability and practice effects.…”
