Note.

a

Factor loadings are directly obtained from RRR analysis; these are the loadings of each symptom on the latent symptom factor.

b

Standard score parameters are obtained from multiple linear regression of symptoms on total symptom score; these are regression coefficients describing the strength of association of each symptom with the total symptom score.

c

Pearson’s correlation coefficient is the correlation of each individual symptom with the total symptom score.

d

Explained variation is the total variation in the latent symptom factor (symptom score) explained by each symptom; it is calculated by multiplying standardized parameters with the Pearson’s correlation coefficient x 100.
