Abstract

Definition The relationship (correlation) between separate scales or subscales. Description The value between +1 and −1 that represents the correlation between two scales is the interscale correlation. In quality of life literature, interscale correlations are used frequently (Aaronson et al., 1993; Borghede & Sullivan, 1996; Fekkes et al., 2000; Hearn & Higginson, 1997). A researcher may choose to determine the interscale correlation in situations in which she/he has multiple scales and wants to investigate the relationship between the variables that those scales are measuring. Depending on the nature of the research, a high or low interscale correlation could be sought after. In the case of a validity study, a researcher may want to examine how similar a newly created scale is to another scale that is deemed to be a “gold standard.” Finding that the researcher’s scale has a high correlation with the other scale would lend itself to evidence of
