  Reliability: Internal Consistency

  Cronbach's Alpha for all subscale (ɑ>.88)

  Reliability: Other Evidence

  The consistently low standard errors across most the measurement continuum provides confidence in the precision of score estimates, even at the individual level.

  Validity: Construct (Convergent and Discriminant)

  Construct validity is based on correlations between scores on item banks, item bank short forms, and legacy measures:
  (1) Physical function full bank is correlated at r = 0.96 with the short form and -0.80 to -0.88 with legacy measures;
  (2) Fatigue full bank is correlated at r = 0.76 with the short form and .89 to .95 with legacy measures;
  (3) Pain full bank is correlated at r = .98 (behavior) and .95 (interference) with the short form and -.86 to .85 with legacy measures; banks are correlated at r = 0.69
  (4) Sleep full bank is correlated at r = .96 (disturbance) and .98 (sleep-related impairment) with the short form and .25 to .85 with legacy measures; The banks are correlated at r = 0.75
  (5) Emotional distress: correlated at r = .96 (Anger), .96 (anxiety), and .96 (depression); from .51 to .83 with legacy measures; banks are correlated from .51 to .81;
  (6) Social health: correlated at .99 with short forms (for both satisfaction with participation in discretionary social activities and satisfaction with participation in social roles); .44 to .76 with legacy measures; banks are correlated at .93
