Abstract

Highlights: We mapped patients' judgments of satisfaction with pre- to posttreatment changes. Proportion of change outperformed other metrics in modeling patient satisfaction. 50% change in pretreatment HRSD corresponded with our a priori satisfaction level. Abstract: Within mental health, approaches to determine whether a patient experienced "meaningful" change from treatment have predominantly involved imposing thresholds on three types of metrics derived from assessments of symptom severity: end score (posttreatment score), absolute change (pre- minus posttreatment score), and proportion of change. However, none of these approaches have considered input from the consumer. This study examined correspondences between various reductions from pre- to posttreatment symptom severity levels and patients' judgments of satisfaction with change. Former or currently depressed patients were asked to provide judgments of their satisfaction reflected in vignettes that used descriptions from the Hamilton Rating Scale for Depression. Judgments from 108 female participants were fit using four metrics: end score, absolute change, proportion of change, and the combination of end score and absolute change. Akaike information criteria (AICs) and Akaike weights were used to determine the best-fitting model. Cutoffs were calculated for the five levels of satisfaction with change. Proportion of change best accounted for variation in the patients' ratings. For "slightly …, " "somewhat …, " "moderately …, " and "very …, " the proportions of reduction that corresponded with each of these ratings of satisfaction were, respectively: 17%, 39%, 62%, and 84%. Our a priori level of satisfaction (between "somewhat" and "moderately") corresponded to a 50% reduction in pretreatment severity. This study may provide services some insight into their female patients' satisfaction with change from treatment for depression using only the proportion of reduction from pretreatment severity. A similar procedure could be applied to other diagnostic groups, as well as other constructs that attend to the patient's perspective.
