xxx/ellauri104.html on line 665: The Restructured Clinical scales were designed to be psychometrically improved versions of the original clinical scales, which were known to contain a high level of interscale correlation, overlapping items, and were confounded by the presence of an overarching factor that has since been extracted and placed in a separate scale (demoralization). The RC scales measure the core constructs of the original clinical scales.
xxx/ellauri104.html on line 667: Critics of the RC scales assert they have deviated too far from the original clinical scales, the implication being that previous research done on the clinical scales will not be relevant to the interpretation of the RC scales. However, researchers on the RC scales assert that the RC scales predict pathology in their designated areas better than their concordant original clinical scales while using significantly fewer items and maintaining equal to higher internal consistency, reliability and validity; further, unlike the original clinical scales, the RC scales are not saturated with the primary factor (demoralization, now captured in RCdem) which frequently produced diffuse elevations and made interpretation of results difficult; finally, the RC scales have lower interscale correlations and, in contrast to the original clinical scales, contain no interscale item overlap.
