AB  - INTRODUCTION: People with rheumatoid arthritis (RA) frequently suffer from 
      compromised physical and psychological health, however, little is known about 
      positive indicators of health, due to a lack of validated outcome measures. This 
      study aims to validate a clinically relevant outcome measure of positive 
      psychological well-being for people with RA. The first study examined the 
      reliability and factorial validity of the Subjective Vitality Scale (SVS), whilst 
      study 2 tested the instruments convergent validity. METHODS: In study 1, National 
      Rheumatoid Arthritis Society members (N = 333; M age = 59.82 years SD = 11.00) 
      completed a postal questionnaire. For study 2, participants (N = 106; M 
      age = 56 years, SD = 12 years) were those recruited to a randomized control trial 
      comparing two physical activity interventions who completed a range of 
      health-related questionnaires. RESULTS: The SVS had a high level of internal 
      consistency (alpha = .93, Rho = .92). Confirmatory factor analysis supported the 
      uni-dimensional factor structure of the questionnaire among RA patients [chi = 1327 
      (10), CFI = 1.0, SRMSR = .01 and RMSEA = .00 (.00 - .08)]. Support for the scales 
      convergent validity was revealed by significant (p < .05) relationships, in 
      expected directions, with health related quality of life (r = .59), physical 
      function (r = .58), feelings of fatigue (r = -.70), anxiety (r = -.57) and 
      depression (r = -.73). CONCLUSIONS: Results from two studies have provided 
      support for the internal consistency, factorial structure and convergent validity 
      of the Subjective Vitality Scale. Researchers and healthcare providers may employ 
      this clinically relevant, freely available and brief assessment with the 
      confidence that it is a valid and reliable measure of positive psychological 
      well-being for RA patients. TRIAL REGISTRATION: ClinicalTrials.gov ISRCTN04121489
