Abstract Background The Short Form 36 (SF-36) is a scoring system comprising of 36 items categorized into eight constructs corresponding to patients’ health-related quality of life. It has been used extensively in various countries on different sub-populations and used to indicate the health status and help to ascertain the effect of clinical interventions on the particular population. Objective To examine the psychometric properties of the Malay version of SF-36 (Malay SF-36) summated rating scales and validate the scale among post-coronary artery bypass grafting surgery (CABG) patients at the National Heart Institute (IJN), Kuala Lumpur. Methods Five hundred and nine post-CABG patients at the IJN, Malaysia completed the questionnaires between 1 July and 31 December 2017. Psychometric tests endorsed by the “International Quality of Life Assessment Project” were utilised. Results The data quality was excellent with a high questionnaire completion rate (100%). As hypothesized, the ordering of item means within scales was clustered. In unison, scaling assumptions were satisfied. Good discriminant validity was shown between subsets of patients with various levels of health status. Notwithstanding, there were probably translation issues of the Physical Functioning scale which showed small ceiling effects. We clearly observed high ceiling and floor effects in both Role Physical and Role Emotional scale most probably attributed to the dichotomous style of their choice of responses. Cronbach alpha values of the eight scales ranged from 0.73 to 0.90, showing good internal consistency reliability. Confirmatory Factor Analysis (CFA) confirmed the 8-factor solution and Composite Reliability revealed internal consistency reliability except for Vitality and Social Functioning. Based on the Average Variance Extracted (AVE), convergent validity was adequate except for two domains. Discriminant Validity is good for the eight constructs as the √AVE are generally higher than the correlation coefficients between the latent constructs. Conclusion The scoring for the Malay SF-36 based on the summated ratings method was proven to be valid to be applied in our local clinical population. The CFA, fitness estimates, reliability and validity assessments suggest that the Malay version of SF36 is a valid and reliable instrument. However, further work is warranted to further refine the convergent validity and reliability of some scales.

Teamwork is one of the most important factors for business success in the modern economy. In almost every area of business, teams receive more and more attention, since it has been found that teamwork leads to greater individual, group, and even organizational performance. The aim of this research is to investigate the effectiveness of teamwork and its relationship with team performances. Specifically, the authors tried to investigate which factors of teamwork effectiveness have a positive relationship with teamwork performance and the sustainability of teams in the future. The subject of the research is the effectiveness of teamwork as a construct that is widely presented in the scientific field of organizational behavior and human resource management, but is still underexplored in empirical research, especially in the banking sector. An investigation with a self-audit questionnaire on teamwork effectiveness was conducted on a sample of 401 employees in the banking sector in Serbia, in 16 out of the 26 existing banks in the country. The authors used SmartPLS software in order to test the questionnaire (indicator loadings, internal consistency reliability, convergent validity, and discriminant validity) and proposed research question (PLS-SEM). The results showed that factors such as innovative behavior of the team members, the quality of teamwork, and teamwork synergy have positive relations to teamwork performance. This paper contributes to the better understanding of the factors of teamwork effectiveness that contribute to team performances, with respect to the banking industry in Serbia. The limitation of the paper is the size of the sample, with respect to the total population.

Rationale and aims: The MacNew questionnaire is a disease-specific health-related quality of life (HRQL) measure designed for patients with heart disease. We aimed to assess the psychometric properties of the Russian MacNew heart-disease health-related quality of life (HRQL) scale in patients undergoing coronary artery bypass grafting (CABG) surgery.Methods: The sample comprised of 226 Russian-speaking CABG patients. Patients were assessed before CABG surgery and 12 months thereafter. They completed the MacNew, the Short Form-36 Health Survey (SF-36), the Hospital Anxiety and Depression Scale and a questionnaire on demographic and lifestyle habits.Results: Of the 226 patients who completed the questionnaires at study entry, 188 (83%) also provided data after 12 months. The internal consistency of the MacNew scales was high (alpha coefficients: 0.88-0.93). There were moderate to high correlations between similar sub-scales of the MacNew and the SF-36 domains (0.69-0.80). The MacNew scales discriminated between patients varying on four variables: gender, depression, anxiety and congestive heart failure. The original 3-factor structure was generally supported. Patients’ scores on the MacNew scale improved over 12 months suggesting it was responsive to change.Conclusions: The Russian version of MacNew was found to be a reliable and valid HRQL tool which is sensitive to change. This instrument offers clinicians and researchers a useful tool for understanding patient’s perspective of the impact of heart disease and its treatment.

BackgroundQuality of life is the subject of growing interest and investigation.AimsTo develop and validate a short, self-report quality of life questionnaire (the Schizophrenia Quality of Life Scale, SQLS).MethodPeople with schizophrenia in Liverpool were recruited via the NHS. Items, generated from in-depth interviews, were developed into an 80-item self-report questionnaire. Data were factor analysed, and a shorter form measure was tested for reliability and validity. This measure was administered together with other self-report measures – SF–36, GHQ–12 and HADS – to assess validity.ResultsData were analysed to produce a final 30-item questionnaire, comprising three scales (‘psychosocial’, ‘motivation and energy’, and ‘symptoms and side-effects’) addressing different SQLS dimensions. Internal consistency reliability of the scale was found to be satisfactory. There was a high level of association with relevant SF–36, GHQ–12 and HADS scores.ConclusionsThe SQLS was completed within 5–10 minutes. It possesses internal reliability and construct validity, and promises to be a useful tool for the evaluation of new treatment regimes for people with schizophrenia.

Abstract Background In order to predict social, mental and health care needs we must measure Quality of life of residents. In Afghanistan there was no assessment to measure quality of life of people. The aim of this study was to culturally adapt the WHOQOL-BREF into Dari language of Afghanistan and present its psychometric properties. Methods Cultural adaptation of the WHOQOL-BREF into Dari has consisted of two stages: translation stage, and the cognitive debriefing (pilot) stage following the translation stage. The process of translation of WHOQOL-BREF included recommended methodology, mandating forward translation, backward translation was followed. A total number of 1473 people did participate in this research. Psychometric analyses consisted of item analyses; reliability and validity analyses. Internal consistency analyses were done by Cronbach's alpha value and validity analyses consisted of construct validity (convergent validity by SF-36 and confirmatory factor analyses) and criterion validity (multiple linear regression by overall QoL item (item1)) analyses. Acceptable type 1 error was considered as 0.05 in all analyses. Analyses were done by using Lisrel v8.05 statistical package. Results Item domain correlations and -if item deleted- Cronbach alpha values no problematic item in Afghan version of the WHOQOL-BREF. Internal consistency of the scale was in acceptable limits for all domains (alpha values = 0.79–0.80) except for the social relations domain (alpha = 0.41). Using overall QoL item (item q1) as the dependent variable, multiple regression analysis revealed a R2 value of 57% and all of the four domains of the WHOQOL except that of Social relation domain (beta = 0.03) could explain the variance of the q1, the best domain is the environmental domain with a beta value of 0.30. Construct validity is tested by known groups validity; factorial validity and the convergent validity. All of the known categories of the age, gender, education, social class and economic status, having chronic illness were significantly sensitive to the domain scores of the WHOQOL (p < 0.001). Physical and Psychological domains of the WHOQOL-BREF was highly correlated with the related domains of the SF-36 (r = 0.60 and 0.64). Social and environmental domains showed poor correlations with the SF36. Confirmatory factor analyses showed acceptable goodness of fit results. Chi-square = 2174,748 and Degrees of freedom = 246; GFI: 0.88, CFI: 0.83; RMR: 0.066 and RMSEA: 0.073. Conclusion Afghan Dari version of the WHOQOL-BREF can confidently be used in clinical setting and in population level to assess the QoL of the people. The results of the social relations domain should be interpreted with caution due to its poor psychometric power. Further studies are needed to address the social aspects of quality of life in Afghan population.

Aims: The purposes of this study were (1) to compare body composition, physical function, and quality of life (QOL) between patients after coronary artery bypass grafting (CABG) with and without chronic kidney disease (CKD) and (2) to analyze the factors associated with physical function and QOL domains in these patients. Methods: Thirty male post-CABG patients with CKD and 30 matched controls were recruited. All subjects underwent dual-energy X-ray absorptiometry for body composition evaluation. Physical function tests included the grip strength test, 30-second chair stand test (30CST), and 6-min walk test (6MWT). Physical activity and QOL were assessed using the long form of the International Physical Activity Questionnaire and the World Health Organization Quality of Life Instrument (WHOQOL)-BREF, respectively. Results: Post-CABG patients with CKD exhibited a lower arm lean mass and higher percent leg fat mass than those without CKD (p < 0.05). The patients with CKD also had lower 30CST scores, 6MWT distances, and QOL domain of social relationships scores than those without CKD after adjusting for covariates (p < 0.05). If NYHA class was considered in the model, NYHA class became the most important factor associated with 6MWT distances (β = -0.647, p < 0.001) and the QOL domains of psychological health (β = -0.285, p = 0.027) and environment (β = -0.406, p = 0.001). Conclusion: Post-CABG patients with CKD had worse body composition, physical function, and QOL than those without CKD, and this might be associated with a worse NYHA class.

Aim. To analyze quality of life (QOL) of patients with coronary artery disease (CAD) in combination with long-standing persistent atrial fibrillation (AF) in the long-term postoperative period, depending on chosen surgical strategy for concomitant pathology.Material and methods. The analysis of QOL changes in the long-term postoperative period (12 and 24 months) in 116 patients with CAD and concomitant long-term persistent AF who selectively underwent biatrial (BA) or isolated left atrial (LA) ablation with simultaneous on-pump coronary artery bypass grafting. To assess QOL, a non-specific Medical Outcomes Study 36-Item Form Health Status Survey (SF-36) questionnaire was used. Patients were questioned in preoperative and long-term postoperative periods (12 and 24 months).Results. All SF-36 parameters significantly improve after open surgical treatment in the long-term postoperative period (24 months) with both treatment strategies (BA and LA ablation) for AF. In the BA ablation group, 74% of patients did not have arrhythmia after 12 months, and only 38,5% of patients in the LA ablation group belonged to European Heart Rhythm Association (EHRA) score class 1 (p=0,001). After 24 months, a comparison revealed a significant diff erence between the two groups in arrhythmia symptoms (p=0,014), with maintaining the advantage of the BA ablation group. After 12 and 24 months, none of the patients in both compared groups had severe class IV angina.Conclusion. SF-36 parameters were improved 24 months after surgical treatment of CAD and long-standing persistent AF, regardless of the ablation strategy. Elimination of angina symptoms and long-term maintenance of sinus rhythm can improve the QOL  of patients in the long-term postoperative period.

Summary: The aim of this study was to validate the use of short, generic, quality-of-life (QoL) questionnaires in a population of myocardial infarction survivors. The feasibility, reliability, and validity of two short questionnaires (the MOS-24 and the COOP/WONCA charts) were evaluated and compared with a long questionnaire (the Sickness Impact Profile). The study population consisted of 99 myocardial infarction survivors some years after the event and 101 referents without a history of heart or brain infarction. The feasibility of the short questionnaires was good. Both instruments covered the most important domains of QoL, similar to the Sickness Impact Profile. In addition, the two short questionnaires measured “pain” and the MOS-24 also covered “vitality.” The MOS-24 had a smaller floor effect than the COOP/WONCA charts. The MOS-24 was shown to be a reliable test. Both short instruments were able to detect between-group differences (especially MOS-24) although at different rates. Convergent validity of the MOS-24 was high compared with the COOP/WONCA charts. In contrast, the discriminant validity of the COOP/WONCA charts was better. The discriminant validity of the MOS-24 was, nevertheless, reasonable. In conclusion, both instruments are suitable for measuring the QoL of myocardial infarction survivors. The multi-item MOS-24 questionnaire however, is slightly preferable.

The aim of this study was to examine the quality of life and to report on the utility and QALY measures in patients before and after coronary artery bypass grafting (CABG); to investigate whether the SF-12 is comparable with the SF-36 for measuring health-related quality of life of patients with CABG; and to determine the impact of individual predictors on poor quality of life assessment after rehabilitation. This prospective study was conducted between January 2017 and December 2018 at the University Hospital Center Osijek, at three time points: pre-operation, 1 month after surgery, and after rehabilitation. The study was conducted with the SF-36 and SF-12 health questionnaires on 47 participants. After rehabilitation, there was a significant improvement in all domains of quality of life. The highest score was given to the change in pain (BP); mean scores were 63.8 (95% CI 56.9 to 70.6) (p = 0.001). The lowest grade (the lowest quality) after rehabilitation was in the domain of limitations due to physical difficulties (RP); arithmetic mean was 48.5 (95% CI 41 to 55.9) (p < 0.001). Quality-adjusted life-year was 0.41 (95% CI 0.38–0.44) after the CABG. The results of this study show that patients with coronary heart disease have poor quality of life before surgery. One month after the surgery, the quality of life improved, but was still inadequate. One year after surgery, satisfactory results were obtained in almost all subscales. The SF-36, SF-12, and its components, can be used effectively in patients with CABG. Age, gender, lifestyle, and risk factors in our sample of participants are not predictors of poor quality of life assessment after rehabilitation.
