Sentences with phrase «polychoric ordinal»

The SDQ subscales obtained from the online administration showed high internal consistency (polychoric ordinal alpha), and confirmatory factor analysis of the SDQ five factor model resulted in excellent fit.

Due to some skewness and / or kurtosis on some items on the SDQ and the DBD, polychoric ordinal alpha (Gadermann et al. 2012) was calculated instead of Cronbach's alpha when more appropriate.

The internal consistency (polychoric ordinal alpha) of the subscales of the DBD ranged between 0.94 and 0.99.

These studies have not used polychoric ordinal alpha, but instead Cronbach's alpha, which might explain some of the differences.

The internal consistency of the SDQ (polychoric ordinal alpha) ranged between 0.84 and 0.91 (emotional problems: 0.89, hyperactivity — inattention: 0.88, peer problems: 0.84, prosocial behaviour: 0.91, and conduct problems: 0.88).

Given the large skewness and kurtosis of three of its items, polychoric ordinal alpha was used to investigate the internal consistency.

The internal consistency (polychoric ordinal alpha: Please see Statistical analysis) of the subscales of the DBD varied between.97 and.99.

Not exact matches

Due to the ordinal and categorical nature of the response options, reliability was assessed using polychoric correlation - based version of the reliability coefficients.45 These analyses suggested satisfactory internal consistency for the SDQ total difficulties scale (α = 0.86) and for all subscales (α emotional problems = 0.82, conduct problems = 0.71, hyperactivity — inattention = 0.76, peer problems = 0.75 and prosocial behaviours = 0.77).

Because of the multivariate nonnormality of the data and the ordinal, noncontinuous nature of the item data, the CFA model was specified via a polychoric correlation matrix and asymptotic covariance matrix and an unweighted least squares estimation method.39, 40 The matrices were generated in PRELIS 9.2 and analyzed with LISREL 9.241 and are available on request.
