CMINDS® Test Design and Structure

 

CMINDS® tests are designed to achieve nearly identical face validity and structure in relation to their antecedent, paper-based counterparts. Moreover, equivalent face validity ensures test/retest reliability indistinguishable from, or even superior to, the paper-based antecedents. Accordingly, CMINDS® tests exhibit excellent construct validity and concurrent validity when compared to traditional versions of these established assessment instruments.

Importantly, content (i.e. test instructions and stimulus materials) for some CMINDS® tests is either in the public domain (e.g. Controlled Oral Word Association and Category Instances) or is new content created by NeuroComp in consultation with expert psychometrists. New content utilized in CMINDS® includes: alternate word lists for the CMINDS® Semantic Verbal Learning Test (SVLT), based on the HVLT-RTM* and alternate card materials for the WCSTTM*, alternate patterns for Trails A&B, alternate letter-number sequences for the Letter-Number Ordering Test and alternate symbols for the Symbol Digit Modalities Test**.

Thus, CMINDS® tests are not unique or "proprietary" designs that have been created or "adapted" to enable implementation on a single-display computerized system. Rather, the flexibility and response capture range of the CMINDS® examiner-assisted schema enables computerized versions of common tests utilizing the same structure (e.g. presentation, number of trials) and procedures (e.g. administration and scoring).


Comparison of Paper-Based Trial Making (A & B) with CMINDS®
Paper Version CMINDS® Computerized Version
  • The examiner presents a paper form comprised of circled numbers (A)/letters & numbers (B).
  • The computer presents an electronic form comprised of circled numbers (A) / letters & numbers (B).
  • The subject is instructed to draw lines connecting the circles, starting with #1 and connecting them in order until the end.
  • The subject is instructed to draw lines connecting the circles, starting at #1 and connecting in order, until the end.
  • The examiner visually detects errors committed by connecting circles out of sequence. The examiner then immediately advises the subject verbally by saying: “Stop and go back to the previous circle and connect the circles in order”.
  • The computer automatically detects errors committed by touching circles out of sequence. In CMINDS®, the previously touched circle begins to flash and a digitized human voice prompts: “Stop and go back to the flashing circle and connect the circles in the correct order."
  • The subject is instructed not to lift the tip of the pencil from the paper while connecting the circles.
  • The subject is instructed not to lift the tip of the pen from the screen while connecting the circles. CMINDS® automatically detects if the subject lifts the tip of the pen from the screen and a prompt is given.
