“…Several authors have demonstrated the reliability and validity of SF-36 questionnaire and their two factors structure in patients suffering from different diseases (Alonso et al 1995;Lam et al 2005;Vilagut et al 2005;Lugo et al 2006;Wollmerstedt et al 2006;Mohammadpour and Yousefi 2008). Furthermore, studies performed in USA, Australia, UK and China have demonstrated the reliability and validity of SF-36 questionnaire and their two factors structure in older people (Syddall et al 2009;Bohannon and DePasquale 2010;Walters et al 2001;Bartsch et al 2011;Hu et al 2010). In the present study, the two summary measures explained 65.3 % of the total variance and 74.2 % of the reliable variance.…”

“…Important gender inequalities were observed in all of these results, being consistently less favourable in women than in men. Bartsch et al (2011) reported that men had better health than women, with the exception of the vitality scale. Similar results were found by Chan et al (2006) and Chachamovich et al (2008) where depression was an important predictor of impairments in quality of life and attitudes towards ageing for older adults.…”

“…However only in the USA, UK, Australia and China, SF-36 was validated for older people (Syddall et al 2009;Bohannon and DePasquale 2010;Walters et al 2001;Bartsch et al 2011;Hu et al 2010).…”

To validate short-form-36 health survey (SF-36) with specific scoring algorithm obtained in a large sample of Chilean older people and to associate quality of life in this sample with social and health related factors. A cross-sectional study on 2,143 community-living subjects aged 60-92 years (33 % men and 67 % women) conducted in Santiago, Chile. Scores in 8 scales of SF-36-physical function (PF), role physical (RP), bodily pain (BP), general health (GH), vitality (VT), social functioning (SF), role emotional (RE) and mental health (MH)-, were calculated. Factor analysis was used to extract two principal factors and logistic regression model was applied to estimate its association with socio-demographic and health variables. The internal consistency of scales was high (Cronbach's alpha 0.86-0.87). Factor analysis retained two factors: mental (MCS) and physical (PCS) components accounting for 65.3 % of total variance (55.3 and 10.0 % respectively). High correlations (0.61-0.94) between MCS and MH, V, RE and SF were obtained. PCS correlated highest (0.72-0.86) with RP, PF and BP. Self-perceived symptoms of depression (GDS-15 C5) was the main variable explaining low scores in both MCS and PCS (adjusted OR = 26.9; 95 % CI: 15.3-47.2; OR = 3.4; 95 % CI: 2.1-5.5, respectively). We have demonstrated the reliability and validity of SF-36 questionnaire to evaluate health related quality of life, reporting Chilean-Specific factor score coefficients for MCS and PCS based in national Chilean means and standard deviations for older people. After adjusting by age and gender, the main predictors of low health related QoL in Chilean older people were selfperceived symptoms of depression, the presence of two or more chronic diseases and illiteracy. Important gender inequalities were observed in all of these results, being consistently less favorable in women than in men.

“…Analyses of depression prevalence [18] and dementia prevalence [19] in DYNOPTA do not suggest a healthy cohort effect. Bartsch and colleagues [20] recently reported that Short Form (SF-36) scores in DYNOPTA were similar to those in the 1995 NHS. It is difficult to make direct comparisons given the nationally used age bands may hide any variations in health.…”

“…In the first Australian national household panel survey involving 13,055 respondents, SF-36 was shown to be psychometrically sound, with good internal consistency, discriminant validity and high reliability across its eight scales [28]. The psychometric properties of SF-36 were further established in Australia from the data drawn from five studies with 41,338 participants aged 45 to 97 years in the Dynamic Analyses to Optimise Ageing (DYNOPTA) project [29]. These results confirmed the structural validity and good internal consistency reliability of SF-36, and were comparable with those found in younger Australian and international samples.…”

Enhancing quality of life in people with disordered eating using an online self-help programme

BackgroundEating disorders are serious mental illnesses that have a significant effect on afflicted individuals’ quality of life. Evidence has shown that they can be improved with treatment. Internet-based interventions are useful in engaging individuals with eating disorders in self-management and treatment. This study aimed primarily to identify the change in quality of life of individuals with disordered eating after participating in an open trial of an Internet-based self-help programme, and compared their quality of life at assessment with that of healthy controls. Factors affecting their quality of life were examined. Secondary outcomes related to symptom improvement were also reported.MethodsThis study included 194 individuals with disordered eating and 50 healthy controls. The former group was recruited from eating disorder outpatient clinics and treatment units, as well as via information disseminated through various Internet websites, while the healthy controls were recruited from university student newspapers and university campuses. The Medical Outcomes Study Short Form Survey (SF-36v2) was used to assess participants’ quality of life. Other measures were used to assess their symptoms and motivational stages of change to recover from an eating disorder. The Wilcoxon signed ranks test and one-way repeated measures ANOVA were used to identify the change in quality of life of individuals with disordered eating from baseline to 1-, 3- and 6-month follow-ups. The Mann–Whitney U test was employed to compare the difference in quality of life between participants with disordered eating and the healthy controls. Spearman rank order correlations were performed to examine the factors associated with quality of life.ResultsThe participants with disordered eating had significantly poorer quality of life than the healthy controls in both physical and psychological domains. The factors associated with their poor quality of life included dieting behaviour, use of laxatives, severe eating disorder psychopathology, depression and anxiety. Over a six-month follow-up period, a significant number of participants engaged in self-help behaviours using the Internet-based programme. They experienced improvements in their quality of life, eating disorder psychopathology, depression severity, anxiety level and motivational stages of change.ConclusionsInternet-based self-help programmes have the potential to enhance quality of life in individuals with disordered eating and could be useful adjuncts to professional treatment.

Abstract: The results confirm the structural validity and internal consistency of the eight scales from the SF-36 with an older population and support its use to assess the health of older Australian adults.
