The Quality of Well-being (QWB) Scale is a preference-weighted
measure of individual general health status that may
be summed to produce an average population health status.
It combines a measure of Symptom/Problem Complexes with
three Scales of functioning (Mobility, Physical Activity
and Social Activity) to produce an expression of Well-being
on a scale of 0.0 (for death) to 1.0 (for asymptomatic
full function). The QWB instrument uses interviewer-administered
questions, with standardized follow-up probes to verify
initial responses, for obtaining data. From these data,
a single QWB score for an individual for a 6 day time
period is computer-generated for analysis. These individual
scores can then be combined into general or specific
population scores.
Interviewer-administered questionnaires have been shown,
overall, to provide a better correlation with actual
state of health (determined by established procedures)
than do self-administered questionnaires. QWB scores
have been used, for example, for monitoring change in
individual health status over time or evaluating the
effect of a particular health treatment, policy or program
on the health of a patient population.
The QWB package includes the questionnaire, an interviewer’s
manual, examples of training interviews and
the software required for entry of QWB data into data
files and the derivation of QWB Scale scores. The software
is available as QWB-DOS Application, as well as SPSS-PC,
SPSS-MAC and SPSS Windows programs for running on standard
PC or MAC desktop computers.
