Objectives: Since the study on the elderly people and recording related data requires more accuracy, the calculation of measurement error is very important. This study aims to introduce a simple formula to obtain and interpret the Total Deviation Index (TDI) and encourage researchers to use it as a suitable tool to determine the reliability in psychometrics studies. Methods & Materials: In this cross-sectional study conducted in 2019, participants were 105 older adults living in Tehran, Iran. The 36-Item Short Form Health Survey (SF-36) questionnaire was completed by them within two weeks. The Intraclass Correlation Coefficient (ICC) and TDI values were calculated and compared for each subscale of the SF-36. Results: The lowest TDI value belonged to the “physical functioning” subscale, while the “emotional problems” subscale had the highest TDI value. At a 95% confidence interval, the maximum measurement errors in physical functioning and emotional problems were reported 22 and 34 (out of 100), respectively. Conclusion: Since the ICC cannot determine how much of the difference in the subscale scores is related to the measurement error, and given the simple interpretation of the TDI, it is recommended that researchers use the proposed formula and obtain the TDI value for the reliability in psychometrics studies.

Abstract Purpose Pituitary diseases severely affect patients’ health-related quality of life (HRQoL). The most frequently used generic HRQoL questionnaire is the Short Form-36 (SF-36). The shorter 12-item version (SF-12) can improve efficiency of patient monitoring. This study aimed to determine whether SF-12 can replace SF-36 in pituitary care. Methods In a longitudinal cohort study (August 2016 to December 2018) among 103 endoscopically operated adult pituitary tumor patients, physical and mental component scores (PCS and MCS) of SF-36 and SF-12 were measured preoperatively, and 6 weeks and 6 months postoperatively. Chronic care was assessed with a cross-sectional study (N = 431). Mean differences and agreement between SF-36 and SF-12 change in scores (preoperative vs. 6 months) were assessed with intraclass correlation coefficients (ICC) and limits of agreement, depicting 95% of individual patients. Results In the longitudinal study, mean differences between change in SF-36 and SF-12 scores were 1.4 (PCS) and 0.4 (MCS) with fair agreement for PCS (ICC = 0.546) and substantial agreement for MCS (ICC = 0.931). For 95% of individual patients, the difference between change in SF-36 and SF-12 scores varied between −14.0 and 16.9 for PCS and between −7.8 and 8.7 for MCS. Cross-sectional results showed fair agreement for PCS (ICC = 0.597) and substantial agreement for MCS (ICC = 0.943). Conclusions On a group level, SF-12 can reliably reproduce MCS in pituitary patients, although PCS is less well correlated. However, individual differences between SF-36 and SF-12 can be large. For pituitary diseases, alternative strategies are needed for concise, but comprehensive patient-reported outcome measurement.

ABSTRACT Objective: To evaluate the properties of the Identity-Consequence Fatigue Scale (ICFS) in patients with lung cancer (LC), assessing the intensity of fatigue and associated factors. Methods: This was a cross-sectional study involving LC patients, treated at a teaching hospital in Brazil, who completed the ICFS. Patients with chronic heart disease (CHD) and healthy controls, matched for age and gender, also completed the scale. Initially, a Brazilian Portuguese-language version of the ICFS was administered to 50 LC patients by two independent interviewers; to test for reproducibility, it was readministered to those same patients. At baseline, the LC patients were submitted to spirometry and the six-minute walk test, as well as completing the Epworth Sleepiness Scale (ESS), Hospital Anxiety and Depression Scale (HADS), Medical Outcomes Study 36-item Short-Form Health Survey (SF-36), and Fatigue Severity Scale (FSS). Inflammatory status was assessed by blood C-reactive protein (CRP) levels. To validate the ICFS, we assessed the correlations of its scores with those variables. Results: The sample comprised 50 patients in each group (LC, CHD, and control). In the LC group, the intraclass correlation coefficients for intra-rater and inter-rater reliability regarding ICFS summary variables ranged from 0.94 to 0.76 and from 0.94 to 0.79, respectively. The ICFS presented excellent internal consistency, and Bland-Altman plots showed good test-retest reliability. The ICFS correlated significantly with FSS, HADS, and SF-36 scores, as well as with CRP levels. Mean ICFS scores in the LC group differed significantly from those in the CHD and control groups. Conclusions: The ICFS is a valid, reliable instrument for evaluating LC patients, in whom depression, quality of life, and CRP levels seem to be significantly associated with fatigue.

Abstract Background: We sought to assess the associations between nutrition and ambulation, daily activity, quality of life (QOL), and fatigue in individuals with mild-to-moderate disability with multiple sclerosis (MS). Methods: This cross-sectional pilot study included 20 ambulatory adult volunteers with MS (14 women and 6 men; mean ± SD age, 57.9 ± 10.2 years; mean ± SD Expanded Disability Status Scale score = 4.1 ± 1.8). Primary outcome variables included dietary assessment and the 6-Minute Walk Test (6MWT). Secondary measures included the Timed 25-Foot Walk test, Timed Up and Go test, daily activity, and three self-report questionnaires: the 12-item Multiple Sclerosis Walking Scale, the 36-item Short Form Health Survey (SF-36), and the Modified Fatigue Impact Scale. Results: Significant correlations were seen between the percentage of diet comprising fats and the 6MWT (r = 0.51, P = .02) and the physical functioning component of the SF-36 (r = 0.47, P = .03). The percentage of carbohydrates was significantly correlated with the 6MWT (r = −0.43, P = .05), daily activity (r = −0.59, P = .005), and the physical functioning component of the SF-36 (r = −0.47, P = .03). Cholesterol, folate, iron, and magnesium were significantly positively correlated with the physical functioning component of the SF-36 and the 6MWT. Conclusions: These findings indicate better ambulation, daily function, and QOL with increased fat intake, decreased carbohydrate intake, and increased intake of the micronutrients cholesterol, folate, iron, and magnesium in people with mild-to-moderate MS. This pilot study highlights the potential impact of diet on function and QOL in MS.

Introduction. The Manchester Foot Pain and Disability Index (MFPDI) is a 19-item questionnaire for the assessment of disability caused by foot pain. The aim was to develop a Danish language version of the MFPDI (MFPDI-DK) and evaluate its reproducibility and construct validity. Methods. A Danish version was created, following a forward-backward translation procedure. A sample of 84 adult patients with foot pain was recruited. Participants completed two copies of the MFPDI-DK within a 24- to 48-hour interval, along with the Medical Outcomes Study Short Form 36 (SF-36), and a pain Visual Analog Scale (VAS). Reproducibility was assessed using the intraclass correlation coefficient (ICC) and 95% limits of agreement (Bland-Altman plot). Construct validity was evaluated with Pearson’s Rho, using a priori hypothesized correlations with SF-36 subscales and VASmean. Results. The MFPDI-DK showed very good reliability with an ICC of 0.92 (0.88–0.95). The 95% limits of agreement ranged from −6.03 to 6.03 points. Construct validity was supported by moderate to very strong correlations with the SF-36 physical subscales and VASmean. Conclusion. The MFPDI-DK appears to be a valid and reproducible instrument in evaluating foot-pain-related disability in Danish adult patients in cross-sectional samples. Further research is needed to test the responsiveness of the MFPDI-DK.

CONTEXT AND OBJECTIVE: Quality of life (QoL) is considered important as an outcome measurement, especially for long-term diseases such as chronic renal failure. The present study searched for predictors of QoL in a sample of patients undergoing dialysis in southern Brazil. DESIGN AND SETTING: This was a cross-sectional study developed in three southern Brazilian dialysis facilities. METHODS: Health-related QoL of patients on hemodialysis or peritoneal dialysis was measured using the generic Short Form-36 (SF-36) health survey questionnaire. The results were correlated with sociodemographic, clinical and laboratory variables. The analysis was adjusted through multiple linear regression. RESULTS: A total of 140 patients were assessed: 94 on hemodialysis and 46 on peritoneal dialysis. The mean age was 54.2 ± 15.4 years, 48% were men and 76% were white. The predictors of higher (better) physical component summary in SF-36 were: younger age (β-0.16; 95% confidence interval, CI: -0.27 to -0.05), shorter time on dialysis (β-0.06; 95% CI: -0.09 to -0.02) and lower Khan comorbidity-age index (β 5.16; 95% CI: 1.7-8.6). The predictors of higher mental component summary were: being employed (β 8.4; 95% CI: 1.7-15.1), being married or having a marriage-like relationship (β 4.56; 95% CI: 0.9-8.2), being on peritoneal dialysis (β 4.9; 95% CI: 0.9-8.8) and not having high blood pressure (β 3.9; 95% CI: 0.3-7.6). CONCLUSIONS: Age, comorbidity and length of time on dialysis were the main predictors of physical QoL, whereas socioeconomic issues especially determined mental QoL.

Objective Osteochondral allograft transplantation is a procedure to treat focal osteochondral lesions (OCLs), but is limited by tissue availability, the quality of transplanted tissue, and inconsistent storage protocols. The objective of this study was to assess the clinical outcomes of a novel tissue procurement, storage, and quality control protocol in treating OCLs. Design Prospective case series. Donor cadaveric tissue was processed, stored, and the tissue quality analyzed using the unique tissue preservation protocol developed at our institution. Advanced cross-sectional imaging was used to size match donor tissue with recipient patients. Osteochondral allografts were transplanted using the Arthrex Allograft OATS. Patients were evaluated with the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Knee injury and Osteoarthritis Outcome Score (KOOS), visual analog scale (VAS), and 36-Item Short Form Survey (SF-36) preoperatively and at 1 year and 2 years postoperatively. Results Twenty patients (17 knees, 3 shoulders) were included in the study. There was a significant improvement in the following scores: overall WOMAC score, WOMAC function and pain subcategories; KOOS pain, knee-related symptoms, activities of daily living, sports and recreation, and quality of life; SF-36 physical functioning, physical role, pain, and social functioning subcategories; and VAS at all time points postoperatively. There was a significant improvement in WOMAC stiffness at 2 years postoperatively. There were 2 failures, defined by graft subsidence and persistent pain requiring reoperation. Conclusion The protocol developed at our institution for OAT resulted in significant clinical improvement in patients with OCLs and is an improvement on existing tissue storage techniques.

ABSTRACT Objective: To evaluate clinical and functional results of patients with lumbar degenerative spondylolisthesis treated with operatively or nonoperatively. Methods: Patients with degenerative spondylolisthesis treated either nonoperatively or operatively from 2004 to 2014 were selected from databases and a cross-sectional evaluation was performed. Outcome measures included back and leg visual analogue scales (VAS), Fischgrund criteria, Short Form-36 (SF-36) function score, and the modified Oswestry Disability Index (ODI). Results: 43 patients were evaluated: 20 with nonoperative treatment and 23 with operative treatment. Baseline characteristics were similar without significant differences between groups. Mean follow-up time was 43 months (range 10 - 72) for the nonoperative group and 36 months (range 6-80) for the operative group. Significant statistical difference in favor of operative group were found in back VAS (mean 4 versus 8, p = 0.000), leg VAS (mean 3 versus 6, p = 0.0015), SF-36 function score (mean 77 versus 35, p = 0.000), and ODI (mean 17 versus 46, p = 0.000). On the basis of the Fischgrund criteria, only 10 % of patients reported excellent or good health post nonoperative treatment versus 83% for those treated operatively (p = 0.000). Conclusion: In this cross-sectional study, we observed that symptomatic patients with degenerative spondylolisthesis who underwent operative treatment have superior clinical and functional scores compared to those that underwent nonoperative treatment.

The Minnesota Living with Heart Failure Questionnaire (MLHFQ) has been developed to measure health-related quality of life (HRQoL) status of Heart Failure (HF) patients. The aim of this study was to translate MLHFQ into the Persian version and assess the validity and reliability of the translated version. We used a forward-backward procedure for translation. In a cross-sectional study, 105 HF patients and 50 healthy subjects were selected to assess the reliability and construct validity of the instrument. The face and content validity were used to assess the questionnaire validity. Validity was examined on the HF patients group, using the Persian version of the Short form-36 health survey (SF-36) Questionnaire. In order to assess the questionnaire’s reliability, the Intraclass correlation coefficient (ICC) and Cronbach’s alpha were calculated. Test-retest reliability was examined by re-administering the MLHFQ after 2 weeks. Test-retest results demonstrated that the Persian version has excellent reliability (ICC for all 2 domains were higher than 0.91, P≤0.000). Internal consistency for Physical domain (PD), emotional domain (ED) and total scores using Cronbach’s alpha were 0.90, 0.84 and 0.92, respectively. ICC for PD, ED and total scores were 0.95, 0.94, and 0.97, respectively. Good and very good Pearson's Correlation Coefficient was seen between MLHFQ and SF-36 (r= -0.47 to -0.775, P≤0.000 for PD; r= -0.47 to -0.65, P≤0.000 for ED). The Persian version of the MLHFQ had satisfactory reliability and validity for assessing HRQoL status of Iranian HF patients. © 2019 Tehran University of Medical Sciences. All rights reserved.

Background: The prevalence of sleep disorders increases as pregnancy progresses, which affects the health of pregnant women, fetal health, and the outcomes of pregnancy. The aim of this study is to evaluate the quality of sleep and life in pregnant women in Korea.Methods: This study is a prospective cross-sectional, case-control study of pregnant women and age-matched controls. From July to September 2019, all participants completed Korean-language versions of the sleep questionnaires including Pittsburgh sleep quality index (K-PSQI), Insomnia severity index, Epworth sleepiness scale, Back’s depression inventory-2(K-BDI), STOP (Snoring, Tiredness, Observed apneas, and high blood Pressure), and short-form 36 (K-SF-36).Results: A total of 422 participants consisted of 385 pregnant women and 137 controls. Second and third trimester were 200 and 185, respectively. K-PSQI scores were higher in pregnant women compared with the controls (7.87±3.49 and 8.50±3.55 vs. 5.79±2.76, <i>p</i><0.001). Total score of K-SF-36 was lowest in third trimester (62.07±17.72) and highest in the control group(79.41±13.36). There was no statistical difference between groups in K-BDI.Conclusions: This study demonstrated worsening of sleep quality as well as life quality during pregnancy. More attention to sleep of pregnant women is needed.

Object. The aim of this study was to assess whether outcomes from excision of acoustic neuroma vary among patients and have a material impact on their quality of life (QOL). Methods. A questionnaire concerning postoperative symptoms and the Short Form 36 (SF-36) QOL instrument were mailed to 97 consecutive patients who had undergone acoustic neuroma surgery via the translabyrinthine approach. The survey response rate was 78% and the symptomatology was consistent with other reports, supporting the representativeness of the sample. The respondents' QOL was rated significantly below published norms and their work capacity was reportedly reduced. Specifically, the following SF-36 dimensions were reduced: physical functioning and role-physical, together with vitality, general health, and social functioning. Greater numbers of postoperative symptoms and larger tumors were associated with a worse rating of physical functioning. More severe balance problems were associated with lower ratings of social functioning. The disparity between the patient's self-estimate and self-measurement and the clinician's assessment of the patient's facial functioning raises doubts about the validity of subjective reports and assessment. Conclusions. The present study supports the use of generic QOL measures to assess outcome and to draw comparisons between different populations.
