Lack of adherence after one month of treatment predicted by baseline hostility and lack of insight. Predictive relationship of hostility and lack of insight at baseline with medication adherence at 1 month of treatment in the study. Logistic regression analysis indicated that both predictor variables reached significance (hostility , lack of insight ). The figure illustrates the combined effect of the two predictors, that is, the probability of lack of full adherence at 1 month (any score of <7 on the Hayward scale) both as a function of lack of insight at baseline (-axis) and hostility (-axis strata depicting additive effects with increasing severity of hostility). Display and computations were provided by Pal Czobor, PhD, who used data collected in the EUFEST study [95, 97].
