The AQoL-8D is a questionnaire used to measure a person's quality of life across eight areas, including mental health and social well-being. It helps compare health outcomes for different treatments, especially when looking at cost-effectiveness.
At a glance
Use when
Evaluating interventions with significant mental health or psychosocial impacts; conducting cost-utility analysis requiring utility weights
Avoid when
Needing a brief screening tool; working in populations where cultural or linguistic validation is lacking
Inputs
Responses to 35-item patient-reported questionnaire across 8 dimensions
Outputs
Utility scores for health states, suitable for QALY calculation in economic evaluations
How it works
The AQoL-8D is a 35-item, 8-dimension multi-attribute utility instrument developed by Monash University Centre for Health Economics. It uses a time trade-off (TTO)-based scoring algorithm to generate utility weights for use in cost-utility analyses. It is distinguished by comprehensive coverage of mental health and psychosocial domains.
- HTA domains
- Clinical Effectiveness, Patient and Social Aspects
- Categories
- HRQoL
- Assumptions
- Respondents can reliably self-report on health dimensions; utility values derived from TTO reflect societal preferences
- Strengths
- Strong psychometric properties; detailed mental health and psychosocial domain coverage; validated for use in cost-utility analysis
- Limitations
- Longer administration time compared to shorter instruments; primarily validated in Australian populations
