“…All SF-36 mean scale scores (not shown) were lower than the respective general population scores reported in the instrument validation study. 25 Scale internal consistency reliability was high (Cronbach's alpha range: 0.79-0.94) and comparable to (or even exceeding) the corresponding coefficients reported in the developmental study of the instrument 20 and other DFS-SF validations. 36 Item internal consistency and discriminant validity were also high, providing evidence to confirm the hypothesized scale structure of the DFS-SF and to suggest that the translation of the items and the response choices are appropriate.…”

“…It was found to have high internal consistency reliability, convergent and discriminative validity and was able to distinguish between groups of respondents in the expected manner (known-groups' validity) on the basis of gender, age, and socioeconomic status. 25 The SF-36 has been shown to discriminate well between perceptions of people with or without one or more chronic diseases 26 and has previously been used to measure HRQoL in greek studies of people with diabetes 27,28 and as a "gold standard" for the validation of the greek diabetes treatment satisfaction questionnaire (DTSQ).…”

ObJECTIvE: Diabetic foot ulcer is a critical and costly complication of diabetes mellitus. The aim of this study was to assess the psychometric properties of the greek version of the diabetic foot ulcer scale -short form (DFS-SF). DESIgN: a sample of patients with diabetic foot ulcer (N=110) was surveyed with the DFS-SF and various demographic and disease-related questions. The validated greek SF-36 instrument was used as a "gold standard" for health-related quality of life comparisons. hypothesized scale structure, internal consistency reliability (Cronbach's alpha) and various forms of construct validity (convergent, discriminative, concurrent and known -groups) were assessed. RESUlTS: multitrait scaling confirmed the scale structure of the DFS-SF, with 32 excellent item convergence (100%) and good discrimination (84.1%) rates. Cronbach's alpha was >0.70 for all scales. Spearman's correlations between similar DFS-SF and SF-36 scales ranged between 0.39-0.79 (p<0.001). Expected interscale correlations and knowngroups comparisons supported construct validity. CONClUSIONS: The observed psychometric properties of the greek DFS-SF imply suitability for assessing health-related quality of life in patients with diabetic foot ulcer. Future studies should focus on generalizability of the results, as well as on specific issues such as longitudinal validity and responsiveness.

“…19 The Greek version of SF-36 has been found to be valid and reliable for HD patients. 13 Many large studies have demonstrated that QoL is a consistent and powerful predictor of death and hospitalization in HD patients. 20 The Dialysis Outcomes and Practice Patterns Study showed that the PCS score of the SF-36 predicts mortality better than the serum albumin levels.…”

“…This version has been found to be valid and reliable. 13 Patients completed the SF-36 questionnaire [International Quality Of Life Assessment Project (IQOLA) SF-36v1 Standard, Greece (Greek)] after every trimester of the study, just before the first dialysis session of the new modality, following the instructions we provided.…”

Can Dialysis Modality Influence Quality of Life in Chronic Hemodialysis Patients? Low-Flux Hemodialysis versus High-Flux Hemodiafiltration: A Cross-Over Study

et al. 2012

Background: Hemodiafiltration with online preparation of the substitution [online high-flux hemodiafiltration (OHDF)] and hemodiafiltration with prepared bags of substitution (HDF) are important, recently widely used renal replacement therapies in patients with end-stage renal disease. However, there is little information on the comparative impacts of these modalities versus conventional low-flux hemodialysis (HD) on the quality of life (QoL) of HD patients. This study investigates the effect of dialysis modality on QoL in chronic HD patients. Methods: In this prospective, randomized, cross-over, open label study, 24 patients were enrolled. Their age were 62 AE 13.34 years (mean AE SD), with the duration of dialysis of 31 AE 23.28 months (mean AE SD). Five of the patients were women. QoL was measured by the Short-Form Health Survey with 36 questions (SF-36) and subscale scores were calculated. Each patient received HD, OHDF, and HDF for 3 months, with the dialysis modality subsequently being altered. They completed the questionnaire of QoL at the end of each period. Results: There were statistical significant differences in QoL for the total .7) and 40.7 (30.2-62.8)], for classic low-flux HD and high-flux hemodiafiltration, for bodily pain [45 (26.9-66.9) and 55 (35.6-87.5)], and for role limitations due to emotional functioning [0 (0-33.3) and 33.3 (0-100)], respectively. The scores did not differ significantly between the two types of hemodiafiltration. Conclusions: Our study indicates that QoL differs significantly among patients receiving low-flux HD and high-flux hemodiafiltration, on total SF-36, bodily pain, and role limitations due to emotional functioning. Convective modalities may offer better QoL than diffusive HD.

“…Quality of life was assessed by means of the Short-Form Health Survey questionnaire [13, 14]. All patients were asked to report (a) any history of syncope in lifetime and (b) the number of their syncopal episodes during the last 12 months, as suggested by the European Society of Cardiology and the American College of Cardiology [15, 16].…”

Background: A high prevalence of minor psychiatric disorders (MPDs) has been reported in patients with vasovagal syncope (VVS). However, the relationship between the psychiatric substrate and syncope remains unclear. Methods: In order to test the hypothesis that MPDs may predispose to VVS, we assessed the prevalence of syncope, the response to head-up tilt test (HUTT) and the efficacy of psychiatric drug treatment in reducing syncopal episodes, in patients with recently diagnosed MPDs. The response to HUTT was compared with that in an equal number of matched (a) patients with VVS and (b) healthy controls. Results: A high rate of patients with MPDs (58%) had a positive HUTT. Additionally, 45% had a history of syncope; among them, the rate of positive HUTT was identical to that in the VVS group (83%). Following psychiatric drug treatment, the number of patients with syncope decreased in the MPD group (6/67 from 30/67, p < 0.01). Psychiatric symptoms and quality of life were also improved. The number of syncopal spells decreased equally in the MPD and VVS groups (0.6 ± 0.5 from 2.5 ± 1.4, p < 0.01, and 0.7 ± 0.5 from 2.7 ± 1.3, p < 0.01, respectively). Conclusion: A high proportion of patients with MPDs experience syncope, associated with a high rate of positive HUTT, comparable to that observed in VVS. Psychiatric treatment results in the improvement of syncopal and psychiatric symptoms. These findings suggest involvement of co-occurring MPDs in the pathogenesis of VVS. Therefore, the diagnosis and treatment of MPDs, when present, may be crucial for the effective therapy of vasovagal syndrome.
