OBJECTIVES: To determine interrater reliability of a classification system for @entity1118 in @entity1 with @entity1566 ( @entity1566 ) and to determine the frequency and characteristics of various @entity158 types as categorized by this system. DESIGN: Independent categorization (based on questionnaires; for 15 @entity1 , questionnaires plus personal interviews) by 2 investigators. SETTING: Community. @entity1 : A total of 163 individuals aged >or=18 years with @entity1566 and @entity158 . INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Pain categories, Short-Form McGill Pain Questionnaire, and @entity1118 Grade questionnaire. RESULTS: Among 41 (25%) questionnaires categorized independently by 2 investigators, strength of agreement in categorizing 68 @entity158 problems was substantial (kappa=.68). For 15 @entity1 whose @entity158 was categorized in @entity1 by 2 investigators, strength of agreement was also substantial (kappa=.66). Among 163 survey respondents with @entity158 , the most common @entity158 was @entity1566 (31.9%). Mean characteristic @entity158 intensity +/- standard deviation for @entity158 , regardless of type, was 61.02+/-18.5 on a scale from 0 to 100. On average, for @entity158 , respondents reported moderate @entity158 (43.70+/-29.4; scale range, 0-100). Although certain @entity158 descriptors were more often associated with a specific type of @entity158 , none was pathognomonic. CONCLUSIONS: Substantial interrater reliability was achieved in determining @entity158 categories by use of responses to a questionnaire with a classification system based on presumed pathology. Adding interviews with @entity1 increased our ability to classify @entity158 but did not improve overall interrater reliability.
