A psychometric examination of the cognitive flexibility scale and its association with Orthorexia Nervosa.

Sample size calculations were based on three criteria: (a) to test dimensionality and internal consistency of the CFS, 10 participants for each item of the scale were guaranteed (n min = 120; [ 31 ]) (b) to detect a practically significant effect size in correlation analyses (ρ = 0.2; [ 32 ]), 193 subjects were required (power = 0.80, α = 0.05); (c) to detect the same effect size in SEM analysis assessing the structural relationship between cognitive flexibility and ON, according to the procedure described in Westland [ 33 ], a minimum of 342 subjects were required (power = 0.80, α = 0.05).
