“…The primary outcome measures were the PCS and MCS; these were converted to Australian weighted T-scores where scores range from 0 (worst possible health) to 100 (best possible health), with 50 as the mean score for the general Australian population. 19 The primary analysis investigated a difference between baseline and time point 1 (1-3 months) scores, and for this paired t-tests were used. Further time points were analyzed using one-way analysis of variance to look for differences between the baseline and additional follow-up time points.…”

Purpose: A genetic diagnosis is an extremely useful tool in the management and care of families with inherited heart diseases, particularly in allowing clarification of risk status of asymptomatic family members. The psychosocial consequences of genetic testing in this group are poorly understood. This longitudinal pilot study sought to determine changes in health-related quality of life in patients and asymptomatic family members undergoing genetic testing for inherited heart diseases.methods: Individuals attending two specialized multidisciplinary cardiac genetic clinics in Australia were invited to participate. Patients undergoing proband or predictive genetic testing for an inherited cardiomyopathy or primary arrhythmogenic disorder were eligible. The Medical Outcomes Short Form-36 (version 2) was administered before the genetic result was given, and follow-up surveys were completed 1-3, 6, and 12 months after the result was given.Results: A total of 54 individuals with hypertrophic cardiomyopathy, familial dilated cardiomyopathy, arrhythmogenic right ventricular cardiomyopathy, and long QT syndrome completed baseline and at least one follow-up survey, including 33 probands and 21 asymptomatic relatives. Physical and mental component scores analyzed at baseline and 1-3 months were found to be unchanged in all groups. Furthermore, no significant differences were observed up to 12 months after result. conclusion:In this longitudinal pilot study, no change in healthrelated quality of life was observed up to 12 months after the result was given in patients and their asymptomatic family members undergoing genetic testing for an inherited heart disease.

“…Die Validität, Reliabilität und Veränderungssensitivität des Instrumentes wurden nachgewiesen [5,6,7,8,9], die internationale Vergleichbarkeit ist gegeben, und es wurde in über 20 verschiedene Sprachen übersetzt [10,11,12]. Eine Suche in der Literaturdatenbank Scopus im Januar 2013 ergab 13.820 Referenzen [13]. Die Version 2 des SF-36 (SF-36V2) misst die gleichen Bereiche wie die Version 1, enthält aber teilweise Veränderungen in der Sprache und den Antwortkategorien und soll verständlicher sein und eine noch bessere interkulturelle Vergleichbarkeit gewährleisten [14,15,16].…”

Mittlerweile wurde der SF-36V2 außer in den USA [17,18,19,20] in weiteren englischsprachigen Ländern wie Australien [13], Neuseeland [21] und Großbritannien [14] und in nicht-englischsprachigen Ländern wie Brasilien [22], China [23], Schweden [24] und Spanien [25] angewendet.

“…Auf das sog. "norm-based scoring" wurde in den einzelnen Skalen verzichtet, um nicht auf die Gewichte der amerikanischen Normstichprobe von 1998 zurück-greifen zu müssen, da diese aufgrund kultureller Unterschiede nicht eins zu eins auf die deutsche Bevölkerung übertragbar sein dürften [13,26,37]. Insgesamt weisen die Ergebnisse des DEGS1 auf eine gute Akzeptanz des SF-36V2 unter den befragten Personen hin.…”

“…Using Australian data to calculate norm-based scores (from the 1995 Australian National Health Survey (n ¼ 18 468)) 21 helps to account for cultural differences in the way in which health and health-related quality of life are viewed between populations. 22 Based on the 36 included items, scores were calculated for each of eight domains (physical functioning, role-physical, bodily pain, general health, vitality, social functioning, roleemotional and mental health). 20 'Role-physical' and 'roleemotional' refer to the presence of problems with work or other daily activities as a result of physical health and mental health, respectively.…”

A bi-directional relationship between obesity and health-related quality of life: evidence from the longitudinal AusDiab study

et al. 2011

Objective: To assess the prospective relationship between obesity and health-related quality of life, including a novel assessment of the impact of health-related quality of life on weight gain. Design and setting: Longitudinal, national, population-based Australian Diabetes, Obesity and Lifestyle (AusDiab) study, with surveys conducted in 1999/2000 and 2004/2005. Participants: A total of 5985 men and women aged X25 years at study entry. Main outcome measure(s): At both time points, height, weight and waist circumference were measured and self-report data on health-related quality of life from the SF-36 questionnaire were obtained. Cross-sectional and bi-directional, prospective associations between obesity categories and health-related quality of life were assessed. Results: Higher body mass index (BMI) at baseline was associated with deterioration in health-related quality of life over 5 years for seven of the eight health-related quality of life domains in women (all Pp0.01, with the exception of mental health, P40.05), and six out of eight in men (all Po0.05, with the exception of role-emotional, P ¼ 0.055, and mental health, P40.05).Each of the quality-of-life domains related to mental health as well as the mental component summary were inversely associated with BMI change (all Po0.0001 for women and Pp0.01 for men), with the exception of vitality, which was significant in women only (P ¼ 0.008). For the physical domains, change in BMI was inversely associated with baseline general health in women only (P ¼ 0.023). Conclusions: Obesity was associated with a deterioration in health-related quality of life (including both physical and mental health domains) in this cohort of Australian adults followed over 5 years. Health-related quality of life was also a predictor of weight gain over 5 years, indicating a bi-directional association between obesity and health-related quality of life. The identification of those with poor health-related quality of life may be important in assessing the risk of future weight gain, and a focus on health-related quality of life may be beneficial in weight management strategies.

The SF36 Version 2: critical analyses of population weights, scoring algorithms and population norms

Abstract: The procedures reported here may be used by other researchers where local effects are suspected. The population norms presented may be of interest. There are statistical artefacts associated with T-scores that have implications for how SF36V2 data are analysed and interpreted.
