S. Priebe et al., DO DIFFERENT SUBJECTIVE EVALUATION CRITERIA REFLECT DISTINCT CONSTRUCTS, The Journal of nervous and mental disease, 186(7), 1998, pp. 385-392
Four subjective evaluation criteria-self-rated symptoms, subjective qu
ality of Life, self-rated needs, and patients' assessment of treatment
-were examined to determine whether they reflect distinct constructs a
nd to what extent they are correlated. The four criteria were assessed
in 90 newly admitted schizophrenia patients, 170 long-term-hospitaliz
ed schizophrenia patients, 154 patients with alcoholism admitted for t
he short term, and 68 patients with alcoholism in long-term rehabilita
tion, using identical instruments. The four criteria show substantial
intercorrelations, except for assessment of treatment in the two acute
treatment groups. One general factor explains between 43% and 55% of
the variance in each group. Factor scores are associated with observer
-rated psychopathology and objective data. The four criteria overlap i
n different patient groups, except in the assessment of treatment in a
cute groups. The use of more than one subjective criterion should occu
r only with specific hypotheses. A better theoretical framework is nee
ded to explain the differences between and interrelationships of subje
ctive evaluation criteria.
