Of the ten MCCB tests, three
have alternate forms: BVMT-R, HVLT-R, and NAB Mazes. The
BVMT-R and HVLT-R have six forms, and NAB Mazes has two
forms. The MCCB test kit includes all six forms of the
BVMT-R, HVLT-R Form 1, and NAB Mazes Form 1 with accompanying
administrator forms and respondent booklets for 25 administrations.
For clinical trials in which the MCCB will be administered
multiple times to each participant, the use of alternate
forms for these three tests is an option that may minimize
practice effects. Alternate forms for the HVLT-R and NAB
Mazes can be ordered as part of the MCCB Retest Packets.

The table above shows the alternate forms recommended
for studies that plan to use two or more alternate forms.
Form 4 of the HVLT-R and Form 5 of the BVMT-R were the
alternate forms used in the MATRICS Psychometric and
Standardization Study with schizophrenia participants.
The recommendations for studies using three to five alternate
forms are based on discussions with the test developers
about the comparability of test forms and their use in
clinical trials with persons with schizophrenia. Form
2 for both measures was slightly less suitable for clinical
trials, and is not recommended for use as part of the
MCCB.
