Note: CI = confidence interval, IPV = intimate partner violence, MCID = minimally important clinical difference, MD = mean difference, SD = standard deviation.
↵* For each subscale, the potential range of scores and the estimated MCID (where MCID was estimated as half the SD for that subscale at baseline,10 based on the 139 participants who responded to the survey at baseline8) were as follows: actual knowledge, potential range of scores 0 to 38, MCID 2.42; perceived preparation to manage IPV, potential range 1 to 7, MCID 0.55; perceived knowledge of important IPV issues, potential range 1 to 7, MCID 0.55; practice issues, potential range 0 to 58, MCID 3.06; preparation, potential range 1 to 7, MCID 0.59; legal requirements, potential range 1 to 7, MCID 0.77; workplace issues, potential range 1 to 7, MCID 0.45; self-efficacy, potential range 1 to 7, MCID 0.22; alcohol and drugs, potential range 1 to 7, MCID 0.28; and victim understanding, potential range 1 to 7, MCID 0.35.
↵† MD was based on multivariable linear regression model comparing baseline score with 12-month score.
↵‡ Data for the workplace issues domain are based on 108 responses (1 participant missed all questions that were part of the workplace issues domain).
