 People devote considerable effort to retaining their mates. Mate retention tactics range from vigilance to
violence, and are linked to variables such as marital satisfaction and relationship aggression. The Mate
Retention Inventory (MRI; 104 items comprising 19 tactics) has proven to be reliable and valid. Given
the importance of assessing mate retention in various contexts, there is a need for a briefer version of
the MRI. In Study 1 (N = 1032), we develop a short form of the MRI (the MRI-SF), which assesses performance
of 19 mate retention tactics using two items per tactic. The tactic scales show internal consistency,
high correlations with the MRI long-form tactic scales, and links with assessments of controlling behavior,
relationship violence, and an assessment of injury. Study 2 (N = 625) replicates the MRI-SF reliability and
high correlations with the MRI long-form tactic scales, and shows links to a sexual coercion measure. We
conclude that the MRI-SF is sufficiently reliable and valid that it can be used in basic and applied research
in place of the MRI long-form for most purposes.
