The standard error in the Jacobson and Truax Reliable Change Index: The classical approach to the assessment of reliable change

Abstract: Researchers and clinicians using Jacobson and Truax's index to assess the reliability of change in patients, or its counterpart by Chelune et al., which takes practice effects into account, are confused by the different ways of calculating the standard error encountered in the literature (see the discussion started in this journal by Hinton-Bayre). This article compares the characteristics of (1) the standard error used by Jacobson and Truax, (2) the standard error of difference scores used by Temkin et al. an… Show more

“…17 In addition to providing a behavioral covariate for correlation with treatment-mediated changes in PDCP expression, this measure was used to divide the subjects into 2 cognitive response categories. This was accomplished by computing the Reliable Change Index (RCI) 19,20 for the verbal learning performance measure as described in appendix e-1 on the Neurology ® Web site at www.neurology.org. An observed verbal learning response above the RCI cannot be ascribed to measurement imprecision (testretest variability) or to between-session practice effects.…”

“…41 To determine that a change was meaningful, we corrected each individual difference in score on each domain by dividing the difference by the standard error (SE) of the difference. If the corrected difference exceeded the 1.65 threshold, we considered this difference meaningful (reliable).…”

“…A French version of the NEO PI-R elaborated by Rolland (Costa, McCrae, Rolland, 1998-2004) which appears to be largely equivalent to the original language version (Rolland, Parker, & Stumpf, 1998) was used in that study. The inventory consisted of 240 items with 30 facet scales and 5 domain scores (N: Neuroticism, E: Extraversion, O: Openness to experience, A: Agreeableness, and C: Conscientiousness).…”
