mo = month; wk = week; min = minutes; CT = change talk; MI = motivational interviewing; MICO = MI consistent; MIIN = MI inconsistent; MI+SO = MI with significant-other participation; MIF =MI with feedback; MIO = MI other.
Session length in minutes based on published report or target session length.
Trimmed estimate with study removed due to less than fair interrater reliability is (r = −.04, 95% CI [−.10, .03]; p = .242, k = 18, Q > .05).
Study used a measure to code in-session behaviors other than MISC [e.g. MITI 2.0 (Moyers et al., 2005), 3.0 (Moyers et al., 2007), 3.1.1 (Moyers et al., 2010), PEPA (Mastroleo, 2009)].
Included study as part of a larger observational measurement development project (Atkins et al., 2014).
