PCA Results Factor loadings of KiddyCAT items (Vanryckeghem & Brutten, 2007) for all participants (N = 114), CWNS (n = 62), and CWS (n = 52). Shaded areas represent loadings that met the criteria (i.e., values ≥ |0.40|) for retention within the factor

Item numbers correspond with their respective questions on the KiddyCAT.

Cronbach’s alpha=0.734 (the estimated internal consistency for all children’s factor loading); Eigenvalue=3.059; percent of variance= 25.491%

Cronbach’s alpha=0.738 (the estimated internal consistency for CWNS’ factor loading); Eigenvalue=3.092; percent of variance=25.766%

Cronbach’s alpha=0.768 (the estimated internal consistency for CWS’ factor loading); Eigenvalue=3.382; percent of variance=28.184%
