TY - JOUR TI - Measuring progress DO - https://doi.org/doi:10.7282/t3-7cb7-8d32 PY - 2018 AB - The successful proliferation of evidence-based measures has left researchers and practitioners the challenge of sifting through a “dizzying array of measures” (Kazdin, 2005, p. 549) in order to select which measures might be appropriate for tracking client progress. The current study used a receiver operating characteristics (ROC) approach in order to investigate how well three common measures of differing breadth were able to classify the outcomes of treatment response, and diagnostic remission, following a 16-week treatment for youth with anxiety (n=165). The three measures included in the study were: a narrow, idiographic measure (Target Problems), a general measure of youth distress (State-Trait Anxiety Inventory for Children-Trait- Child/Parent versions; STAIC-T-C/P), and a broad measure of youth internalizing symptoms (Child Behavior Checklist; CBCL). The measures were first assessed on their ability to classify treatment outcomes over the full course of treatment. Measures that were found to be significant classifiers of each outcome were then compared across three treatment intervals (i.e., intake to week 4, intake to week 8, and intake to week 12) in order to determine how measures performed across time and the earliest point at which each measure was able to classify treatment outcomes. The results of the study found that youth-reported measures were able to classify (1) youth-reported response (2) parent-reported response and (3) diagnostic remission above chance levels. Parent-reported measures classified (1) youth- and (2) parent-reported response above chance levels, but not (3) diagnostic remission. Follow-up ROC analyses revealed that youth-reported STAIC and TP measures performed similarly across treatment when predicting remission but youth-reported STAIC scores outperformed all other measures for the outcome of youth-reported response. Similarly, the outcome of parent-reported response was best classified by parent-reported STAIC scores and the CBCL internalizing scale. The study discusses the advantages and disadvantages of each measure as a classifier of treatment response and diagnostic remission.
