HR & WorkReliability: alpha 0.43–0.71 across 5 modes1 sample item
About this scale
A 30-pair forced-choice instrument measuring five conflict-handling styles: competing, collaborating, compromising, avoiding, and accommodating, organized along the assertiveness × cooperativeness axes.
Sample item(s)
“A) There are times when I let others take responsibility for solving the problem (avoiding) | B) Rather than negotiate the things on which we disagree, I try to stress those things upon which we both agree (smoothing)”
Reliability
Reported internal consistency: alpha 0.43–0.71 across 5 modes. As a rule of thumb, Cronbach’s α ≥ .70 is considered acceptable, ≥ .80 good, and ≥ .90 excellent for established measures.
