Three items measure the extent to which a person believes their brand preferences align with those of their romantic partner. Brick et al. (2018) used the scale as a manipulation check in Study 2, recruiting 415 U.S. MTurk participants who were in relationships of at least six months and cohabiting for at least three months. The scale appears to have been created by the authors.
