  1. Assessing quality of life in patients with cancer : A comparison of a visual-analogue and a categorical model.

    Article - En anglais

    A simple instrument for self-assessment of quality of life (QL) in patients with cancer was elaborated using a linear analogue scale (LAS).

    The instrument was based on five questions, exploring different functional areas ; the same questions were also addressed in a parallel format, where problems were seen from an opposite point of view (positive/negative).

    The LAS was given to 222 patients, for a total of 372 tests collected.

    Internal consistency was satisfactory (Cronbach's alpha=0.75) ; QL score was significantly correlated to parameters of disease.

    Concordance between scales, as judged by comparison of parallel formats, was statistically significant but poor.

    A questionnaire was then elaborated with similar items, based on a categorical scale.

    A direct comparison between LAS and our questionnaire was made on a group of 41 patients.

    Internal consistency was poor for the LAS (alpha=0.58) and good for the questionnaire (alpha=0.93) ; Spearman's rank correlation coefficients were disappointing for the LAS and good for the questionnaire ; the questionnaire was judged reliable in 82.9% ofcases, the LAS in 29.3% only ; the questionnaire score, and not the LAS score, was significantly correlated with PS and disease status.
