![[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],INTRODUCTION A growing body of research supports the utility of monitoring and using client feedback about treatment progress (Anker, Duncan, Sparks, 2009; Lambert, 2010). One increasingly popular method of soliciting client feedback is the Outcome Rating Scale (ORS), an ultra brief (4-item) measure of client functioning (Miller & Duncan, 2000). The ORS assesses psychological functioning along four dimensions: symptom distress, interpersonal relationships, social role functioning, and overall well-being. The ORS offers the reliability and validity of longer measures, but with more feasibility for use in clinical settings (Miller, Duncan, Brown, Sparks, & Claud, 2003). When used in conjunction with the Session Rating Scale, an ultra brief alliance measure, the ORS has been shown to improve therapy outcomes (Anker, et al., 2009; Miller, Duncan, Brown, Sorrell, & Chalk, 2006; Reese, Norsworthy, Rowlands, 2009). Only one study to date has investigated the reliability and validity of the ORS among a non-clinical sample (Bringhurst, Watson, Miller, and Duncan, 2006). The purpose of the present study was to investigate five psychometric characteristics of the ORS: internal consistency, test-retest reliability, factor structure, convergent validity, and discriminant validity. ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],Psychometric Properties of the Outcome Rating Scale in a Non-Clinical Sample Danielle Smith, B.S., Laura Crocker, B.S., Cathy Staton, M.A., Art Gillaspy, Ph.D., and Shawn Charlton, Ph.D. University of Central Arkansas Means, Standard Deviations, and Reliability Coefficients for Study Measures for Administration 1 Factor Pattern Coefficients for ORS Items Bivariate Correlations between ORS, QOLS, and IPAQ for Administration 1 Reliability Coefficients for ORS ORS Items Factor Pattern Coefficients Symptom Distress .69 Interpersonal Relationships .62 Social Role Functioning .76 Overall Well-Being .98 Scale Mean Standard Deviation Cronbach’s Alpha ORS 30.54 5.83 .83 QOLS 86.72 10.92 .85 IPAQ 40.27 22.23 .84 ORS Items ORS Total QOLS IPAQ Symptom Distress .76 .45 .17 Interpersonal Relationships .78 .50 .01 Social Role Functioning .85 .53 .15 Overall Well-Being .91 .53 .14 ORS Total .61 .14 Test-Retest Estimates Individual Functioning .41 Interpersonal Relationships .65 Social Role Functioning .53 Overall Well-Being .40 ORS Total .53](https://image.slidesharecdn.com/orsnonclinicalsample-100511203353-phpapp02/85/ors-in-nonclinical-sample-1-320.jpg)
