WRAP Data Dictionary: AVLT Position Scores

This article describes the "AVLTPositionScores" freeze table and some historical issues that have been identified.

Prior to migration to OpenClinica (OC) for WRAP Cognitive Testing data storage, AVLT Position Scoring data was located in multiple locations (Access (SQL Server) and RedCap). During migration to OC, data from both Access and RedCap was combined and loaded into a new item level tracking form in OC (AVLT).

During the process of migration and data clean-up, several different issues were identified with the item level data (issues documented below). To handle data entry for these issues, a new field "Additional Correct Responses (Not included in item level data)" was created in OC to handle counting values that were not entered into item level data. In either of these cases, when partial item level data is available it is still entered.

Issue 1: "+" used to indicator correct word (only existed in Legacy data)

In the past, some testers did not write the actual word that was said by the participant, instead they indicated a correct word was said using a "+" value. This data could not be converted into item level data, so only total counts are possible on these records. Examples below from different charts.
