A novel use for an established measure: using the Beck Depression Inventory-II to raise insight in patients with schizophrenia

The following study sought to use the Beck Depression Inventory-II (BDI-II) as a means of decreasing depression and delusional ideation, and increasing insight and coping skills in adults with schizophrenia or schizoaffective disorder. Using the BDIII as the independent variable, participants in the experimental group took the BDI-II once per week over the course of six weeks, in order to see if regular exposure to the instrument would lead to significant changes in scores on the Beck Cognitive Insight Scale (BCIS), Peters Delusions Inventory-21 (PDI-21), the Ways of Coping Questionnaire (WAYS), and the BDI-II itself. The control group completed a distraction task in place of the BDI-II for five weeks, and then took the BDI-II during week six for the purpose of comparing depression between groups. At the end of the study, many of the researcher’s hypotheses were weakly supported: the experimental group was less depressed (based on BDI-II scores) at week six than the control group; the experimental group showed slightly greater improvements in insight and moderately greater improvements in delusional ideation compared to the control group; those in the experimental group were marginally more likely to use Planful Problem Solving and slightly more likely to use Positive Reappraisal coping strategies at the end of six weeks than were those in the control group.
