Objectives(i) to demonstrate a method which ameliorates the problem of self-selection in the estimation of population norms from web-based data and (ii) to use the method to calculate population norms for two multi-attribute utility (MAU) instruments, the AQoL-6D and AQoL-8D, and population norms for the sub-scales from which they are constructed.MethodsA web-based survey administered the AQoL-8D MAU instrument (which subsumes the AQoL-6D questionnaire), to members of the public along with the… 
General population norms for the EQ-5D-3 L in Norway: comparison of postal and web surveys
TLDR
The distribution of scores for the EQ-5D descriptive system and its derived utility scores were rather similar in a postal survey and a panel web survey, and these values were combined into a norm set for Norway.
Validation of AQoL-8D: a health-related quality of life questionnaire for adult patients referred for otolaryngology
TLDR
A AQoL-8D provides valid and reliable measures of HRQoL in patients undergoing otolaryngological treatment and because it is a generic questionnaire, it is possible to make general comparisons of otolARYngology outcomes with those from other subspecialties.
Is the Validity of Cost Utility Analysis Improved When Utility is Measured by an Instrument with ‘Home-Country’ Weights? Evidence from Six Western Countries
TLDR
Convergent validity of multi attribute utility instruments with and without home-country weights was compared and it was concluded that the choice of an MAUI for economic evaluation in culturally similar countries should not be based upon the country in which utility weights were estimated but upon a broader consideration of an instrument’s construct validity.
Australian adolescent population norms for the child health utility index 9D—results from the young minds matter survey
Patient-reported outcomes of health-related quality-of-life (HRQoL) are important descriptors of population health. A recent Australian adolescent population survey provided a unique opportunity to
An Exploratory Study: A Head-to-Head Comparison of the EQ-5D-5L and AQoL-8D for Long-Term Publicly Waitlisted Bariatric Surgery Patients Before and 3 Months After Bariatric Surgery
TLDR
AQoL-8D more fully captured the impact of obesity and bariatric surgery on HRZoL (particularly psychosocial impacts) for long-term waitlisted bariatric Surgery patients, even 3 months postoperatively.

HEALTH RELATED QUALITY OF LIFE (HRQOL) – WHAT IT IS AND HOW IT IS MEASURED: STUDIES FROM THE WORLD AND COMPARISON WITH PAKISTAN
TLDR
It is evident that disease-specific studies have been conducted in Pakistan by using various tools, however, no population norms ever reported in Pakistan.
Adult Measures of General Health and Health‐Related Quality of Life
TLDR
This report provides reviews of 4 generic health profiles and 4 health utility measures, including the EuroQol 5-domain, which is also frequently used in rheumatology and is included in Measures of Disability article in this issue.
Exploring health state utility values of parents of children with a serious illness
TLDR
Having a child with a severe illness has an impact on the psychosocial aspects of parental HRQoL regardless of the type of illness, and Psychosocial health factors of trait anxiety, depression and family beliefs were important predictors of parental HSUV.

Modelling utility weights for the Assessment of Quality of Life (AQoL)-8D
TLDR
The AQoL-8D is a suitable instrument for researchers conducting cost utility analyses generally but, in particular, for the analysis of services affecting psycho-social health.

TLDR
The construction of a short HRQoL measure, the Assessment of Quality of Life-8 from the original AQoL, which was a weak scale but reliable and was as sensitive to six common health conditions as the AQeL, EQ5D, and SF6D, including direct comparisons with other short utility measures.
Mapping between 6 Multiattribute Utility Instruments
TLDR
Transformations presented here align the measurement scales of MAU instruments and will increase confidence in the comparability of evaluation studies, which have employed differentMAU instruments.
The SF36 Version 2: critical analyses of population weights, scoring algorithms and population norms
TLDR
There are statistical artefacts associated with T-scores that have implications for how SF36V2 data are analysed and interpreted, and the proportions of cases within T-score deciles show there are important data distribution issues.
Increasing the sensitivity of the AQoL inventory for the evaluation of interventions affecting mental health
This paper presents the rationale and psychometric analysis for extending the inventory of the Assessment of Quality of Life (AQoL)-6D instrument. The resulting AQoL-8D has an 8 dimensional, 35 item
Utility Weights for the Vision-related Assessment of Quality of Life (AQoL)-7D Instrument
TLDR
The AQoL-7D can detect changes in health states affecting people with impaired vision which are likely to be overlooked by other generic instruments due to content insensitivity and its utilities are generated using a “mainstream” methodology, the TTO.
Comparing and Explaining Differences in the Magnitude, Content, and Sensitivity of Utilities Predicted by the EQ-5D, SF-6D, HUI 3, 15D, QWB, and AQoL-8D Multiattribute Utility Instruments
TLDR
Differences between the utilities predicted by the EQ-5D-5L, SF-6D, HUI 3, 15D, QWB, and AQoL-8D imply that commonly used instruments systematically discriminate against some classes of services, most notably mental health services.
The Assessment of Quality of Life (AQoL) instrument: a psychometric measure of Health-Related Quality of Life
TLDR
Preliminary results indicate the AQoL has the prerequisite qualities for a psychometric HRQoL instrument for evaluation; replication with a larger sample is needed to verify these findings.
Multiattribute and Single‐Attribute Utility Functions for the Health Utilities Index Mark 3 System
TLDR
The HUI3 scoring function has strong theoretical and empirical foundations and performs well in predicting directly measured scores and provides a practical way to obtain utility scores based on community preferences.
