Introduction: Quality of life is included in the economic evaluation of health services by measuring the preference for health states, i.e. health state utilities. However, most intervention studies include a disease-specific, not a utility, instrument. Consequently, there has been increasing use of statistical mapping algorithms which permit utilities to be estimated from a disease-specific instrument. The present paper provides such algorithms between the MacNew Heart Disease Quality of Life Questionnaire (MacNew) instrument and six multi-attribute utility (MAU) instruments, the Euroqol (EQ-5D), the Short Form 6D (SF-6D), the Health Utilities Index (HUI) 3, the Quality of Wellbeing (QWB), the 15D (15 Dimension) and the Assessment of Quality of Life (AQoL-8D). Methods: Heart disease patients and members of the healthy public were recruited from six countries. Non-parametric rank tests were used to compare subgroup utilities and MacNew scores. Mapping algorithms were estimated using three separate statistical techniques. Results: Mapping algorithms achieved a high degree of precision. Based on the mean absolute error and the intra class correlation the preferred mapping is MacNew into SF-6D or 15D. Using the R squared statistic the preferred mapping is MacNew into AQoL-8D. Implications for research: The algorithms reported in this paper enable MacNew data to be mapped into utilities predicted from any of six instruments. This permits studies which have included the MacNew to be used in cost utility analyses which, in turn, allows the comparison of services with interventions across the health system.

This paper focusses on coping strategies employed by children and adolescents with diagnosed short stature, assesses the impact of socio-demographic and clinical characteristics on coping, examines the relationship between coping and health related quality of life (QoL) and investigates the role of coping strategies in mediating the relationship between height and QoL. Coping with a disease (CODI) and quality of life in short stature youth (QoLISSY-QoL) questionnaires were completed by 137 short-statured children and adolescents between 8 and 18 years, participating in the crosssectional European QoLISSY study. Clinical and socio-demographic data were collected to examine differences in coping via variance and regression analyses, associations between CODI and QoLISSY were inspected using correlation and mediation analyses. Most frequently employed coping strategies in the CODI were 'Acceptance' and 'Wishful Thinking', with 'Emotional Reaction' used least. Significant effects of age, diagnosis and treatment status on coping strategies were detected. CODI scales 'Acceptance' and 'Distance' were associated with higher QoLISSY-QoL scores, 'Emotional Reaction' and 'Wishful Thinking' with lower scores. Coping strategies predicted 60 % of the QoLISSY-QoL variance. Relationships between height deviation and QoLISSY-QoL were mediated by the coping strategies of 'Wishful Thinking' and 'Distance'. Findings suggest that coping efforts vary with socio-demographic and clinical characteristics, that protective coping strategies in terms of QoL can be identified and that coping mediates the relationship between short stature and QoL. Future longitudinal research should focus on the adaptive function of coping in relation to QoL over time. [ABSTRACT FROM AUTHOR]
