Item-item correlations were moderate and suggested that the individual question items measured distinct constructs.
In addition, subscale reliabilities should be larger that inter-scale correlations to support that scales measure distinct constructs.
Thus, correcting for the attenuation effect did not result in a nearly perfect association, which indicates that the factors measure distinct constructs.
However, the correlations were not unreasonable given the proximity of the constructs in each of the subscales (see Figure 1) and scale reliabilities were larger than inter-scale correlations supporting that CDIP-58 subscales measure distinct constructs.
Others have argued that studies that measure PCB are actually measuring two distinct constructs: self-efficacy, i.e. an individual's belief in his ability to perform certain behaviors, and perceived control, i.e. the individual's belief a behavior is, in general, controllable by an actor (Armitage & Conner 1999; Terry & O'Leary 1995).
42 The Scale of Psychological Well-Being (SPWB) and the QOLS have been differentiated as measuring two distinct constructs.
Examination of convergent and discriminant validity indicated that the two scales measured distinct and specific constructs.
These findings provide evidence to support the validity of the MSRMS as they imply that the four MSRMS subscales were measuring related but distinct constructs, were unrelated to age and disease duration, and were measuring concepts distinct from those measured by the other rating scales.
Moreover, further analyses have revealed that the scale measures a distinct construct of human aggression (for further details see [ 37]).
Because the facets are assumed to measure related but distinct constructs, it was hypothesized that the facets should be significantly, but only moderately, correlated (r = 0.30 0.50).
