Summary. There is extensive literature on the development and validation of multi-item measurement scales. Much of this is based on principles derived from psychometric theory and assumes that the individual items form parallel tests, so that simple weighted or unweighted summation is an appropriate method of aggregation. More recent work either continues to promulgate these methods or places emphasis on modern techniques centred on item response theory. In fact, however, clinical measuring instruments often have different underlying principles, so adopting such approaches is inappropriate. We illustrate, using health-related quality of life, that clinimetric and psychometric ideas need to be combined to yield a suitable measuring instrument. We note the fundamental distinction between indicator and causal variables and propose that this distinction suf®ces to explain fully the need for both clinimetric and psychometric techniques, and identi®es their respective roles in scale development, validation and scoring.

Psychometric properties of the Portuguese version of the beck depression inventory on Brazilian college students

et al. 1999

The psychometric properties of the Portuguese version of the Beck Depression Inventory were studied on a large Brazilian college student sample (N = 1,080; 845 women, 235 men). The BDI scores according to sociodemographic characteristics and mean individual item scores for total sample and by gender were compared. BDI scores tend to be higher for women, for those who work, and for the younger participants. The reliability of the inventory estimated by alpha coefficient was high for the total sample (.86) and subgroups. Factor analysis showed three factors for the total sample (low self‐esteem, cognitive‐affective, and somatic) and two for each gender. Women combined affective and low self‐esteem whereas men combined somatic and low self‐esteem in the same dimension. Discriminant analysis showed that BDI highly discriminates depressive symptomatology in college students and measures specific aspects of depression. © 1999 John Wiley & Sons, Inc.
