Abstract

This study examined the accuracy of depression cross-walk tables in a sample of people with multiple sclerosis (MS). The tables link scores of two commonly used depression measures to the Patient Reported Outcome Measurement Information System Depression (PROMIS-D) scale metric. We administered the 8-item PROMIS-D (Short-Form 8b; PROMIS-D-8), the 20-item Center for Epidemiologic Studies Depression Scale (CESD-20), and the 9-item Patient Health Questionnaire (PHQ-9) to 459 survey participants with MS. We examined correlations between actual PROMIS-D-8 scores and the scores predicted by cross-walks based on PHQ-9 and CESD-20 scores. Intraclass correlation coefficients were used to assess correspondence. Consistency in severity classification was also calculated. Finally, we used Bland–Altman plots to graphically examine the levels of agreement. The correlations between actual and cross-walked PROMIS-D-8 scores were strong (CESD-20 =.82; PHQ-9 =.74). The intraclass correlation was moderate (.77). Participants were consistently classified as having or not having at least moderate depressive symptoms by both actual and cross-walked scores derived from the CESD-20 (90%) and PHQ-9 (85%). Bland–Altman plots suggested the smaller differences between actual and cross-walked scores with greater-than-average depression severity. PROMIS cross-walk tables can be used to translate depression scores of people with MS to the PROMIS-D metric, promoting continuity with previous research.
