Our primary outcome was the measure ’s minimal important difference ( MID ) .
Conclusions In this focused evidence review , the most evidence on key psychometric properties in chronic musculoskeletal pain population s was found for the ODI , RMDQ , SF-36 BPS , NRS , and VAS .
Background Developing successful interventions for chronic musculoskeletal pain requires valid , responsive , and reliable outcome measures .
The Minneapolis VA Evidence -based Synthesis Program completed a focused evidence review on key psychometric properties of 17 self-report measures of pain severity and pain-related functional impairment suitable for clinical research on chronic musculoskeletal pain .
Reliability and Construct Validity of the Patient-Reported Outcomes Measurement Information System (PROMIS) Instruments in Women with Fibromyalgia
Objective The Patient-Reported Outcomes Measurement Information System ( PROMIS ) was developed to st and ardize measurement of clinical ly relevant patient-reported outcomes . This study evaluated the reliability and construct validity of select PROMIS static short-form ( SF ) instruments in women with fibromyalgia . Design Analysis of baseline data from the Fibromyalgia Activity Study with TENS ( FAST ) , a r and omized controlled trial of the efficacy of transcutaneous electrical nerve stimulation . Setting Dual site , university-based outpatient clinics . Subjects Women aged 20 to 67 years diagnosed with fibromyalgia . Methods Participants completed the Revised Fibromyalgia Impact Question naire ( FIQR ) and 10 PROMIS static SF instruments . Internal consistency was calculated using Cronbach alpha . Convergent validity was examined against the FIQR using Pearson correlation and multiple regression analysis . Results PROMIS static SF instruments had fair to high internal consistency ( Cronbach α = 0.58 to 0.94 , P < 0.05 ) . PROMIS ' physical function ' domain score was highly correlated with FIQR ' function ' score ( r = -0.73 ) . The PROMIS ' total ' score was highly correlated with the FIQR total score ( r = -0.72 ) . Correlations with FIQR total score of each of the three PROMIS domain scores were r = -0.65 for ' physical function , ' r = -0.63 for ' global , ' and r = -0.57 for ' symptom ' domain . PROMIS ' physical function , ' ' global , ' and ' symptom ' scores explained 58 % of the FIQR total score variance . Conclusions Select PROMIS static SF instruments demonstrate convergent validity with the FIQR , a legacy measure of fibromyalgia disease severity . These results highlight the potential utility of select PROMIS static SFs for assessment and tracking of patient-reported outcomes in fibromyalgia
