6.2 Confirmatory Factor Analysis for the Disabilities Context
We performed a new Confirmatory Factor Analysis utilizing a modified vignette that accounts for a scenario
where users are augmenting their skills to offset disability-related impairments instead of augmenting to increase
their skills. The original two-factor thirteen items model revealed a sub-optimal fit to this new scenario; the
Root Mean Square Error of Approximation (RMSEA) value was greater than 0.1 and the Comparative Fit Index
(CFI) had a value of 0.96 with a Standardized Root Mean Square Residual (SRMR) of 0.06. Given these values, we
examined the correlations between items using modification indices [50] , which indicate a potential change in
𝜒2 when adding or removing items, We subsequently deleted S2, S11, and, S12 which were highly skewed and
thus had a reduced variance for a disabilities context (more positively valenced responding patterns).
