Abstract

Abstract: The Mobilization-Observation-Behavior-Intensity-Dementia (MOBID) Pain Scale is an observational tool in which raters estimate pain intensity on a 0–10 scale at rest and following five standardized movements. The tool has been shown to be valid and reliable in Norwegian samples only. The purpose of this study was to examine the validity and reliability of the MOBID among English-speaking US NH residents. Validity was examined by correlations 1) between the MOBID overall pain intensity score completed by trained research assistants and an expert clinician's pain intensity rating, and 2) between the MOBID overall pain intensity score and known correlates of pain: agitation, depression, and sleep disturbances. We assessed reliability by calculating Cronbach's alpha. The sample of NH residents observed (n=197) consisted of 51.8% males, 71.1% white, with mean age 84 (SD=10) and mean of 2.9 (SD=2.2) painful diagnoses. Spearman correlation between the MOBID overall scores and expert clinician's rating of worst pain in the past week was statistically significant (rho = 0.51; p <0.001). The correlation between the overall MOBID score and the Cornell Scale for Depression in Dementia was low but statistically significant (rho = 0.19; p = 0.007). No significant correlations were found with agitation or sleep disturbance. Internal consistency was good with a complete data set (n=57; α=0.83), and with imputation methods (n=197; predictive mean matching α=0.69 and random forest α=0.80). Study findings support use of the MOBID in US English speaking populations. Feasibility of completing all movements in a clinical setting will be discussed.
