“…It was because the domains BP, GH, VT, and SF used a single‐item question, in contrast to the α coefficient that was based on the correlation among the items (Maruish, ; Ware et al, ; Ware et al, ). The satisfactory findings were comparable with the Russian (Hoffmann et al, ), Iranian (Montazeri et al, ), Chinese (Lam et al, ), Malay (Noor & Aziz, ), and Korean versions (Kim et al, ). The reliability indicators for the PCS and MCS of the ISF12v2 were closed to the Malay, Iranian, and Korean versions.…”

“…The association between the items and the hypothesized components evidently indicated the results of the discriminant validity of the ISF12v2. These similar trends were also found on the Korean (Kim et al, ), Greek (Kontodimopoulos et al, ), Malay (Noor & Aziz, ), and Iranian versions (Montazeri et al, ), which have coefficient results of more than or equal to 0.30, showing a solid bonding.…”

“…The α coefficient for the MH domain exposed the lowest results. This finding was similar to the Korean version (Kim et al, ). Providentially, the reliability outcome of MH in the ISF12v2 was higher than the Korean version.…”

Aim The aim of this study is to examine psychometric properties of the Indonesian version of Medical Outcome Survey Short Form 12 version 2 (SF12v2). Methods A cross‐sectional study was conducted in three primary healthcare units in Yogyakarta, Indonesia. Patients with cardiovascular diseases who were able to respond to questionnaires and provide their consent were invited. The validity test included face, content, discriminant, and construct validity. The internal consistency was used as the reliability indicator. Results The item and subscale of content validity index were 0.97 and 0.83, respectively. The instrument had 100% for equivalence and clarity outcomes, whereas the readability outcome was 91.7%. More than 80% of participants agreed and considered SF12v2 understandable. The correlations among physical and mental subscales were substantial, supporting discriminant validity. The Bartlett test of sphericity was significant with the Kaiser‐Meyer‐Olkin test of 0.74. The principal component analysis resulted in eight components, explaining 88.4% of total variance. α coefficients for subscale were ranging from.58 to.81, whereas the physical and mental component summaries were.77 and.67, respectively. Conclusions The Indonesian version of SF12v2 indicated a reliable and valid instrument. The SF12v2, available in a Bahasa Indonesia version, is an applicable instrument to assess quality of life on patients with cardiovascular diseases.

“…[22][23][24][25][26][27][28][29][30] The SF-12v2 was used because it was less time consuming to fill questionnaire and has comparable accuracy to the longer SF-36. 31 The scores range from 0 to 100: scores of 100 signify optimal health, while scores that are more or less than 50 are more or less healthy than the American population mean.…”

Background: The aim of this research is to assess the level of physical activity (PA) in relation to different socio-economic factors and to examine the effect of the recommended level of PA on the domains of quality of life (QoL) among residents of low-income housing in the metropolitan area of Kuala Lumpur, Malaysia. Methods: This was a cross-sectional study that included 680 respondents from community housing projects. Reported PA was assessed using the Global Physical Activity Questionnaire (GPAQ) short form version 2. The SF-12v2 was administered to assess the health-related QoL (HRQoL) among the study population. Respondents were grouped into "active" and "insufficient" groups according to reported weekly PA level. One-way analysis of variance, analysis of co-variance, and multiple linear regression were used in the analysis. Results: Overall, 17.6% (95% CI, 14.3-20.9) of the respondents did not achieve the recommended levels of PA (≥600 metabolic equivalent [MET]-minutes week −1 ). Level of achieving recommended PA was higher among younger participants, females, members belonging to nuclear families, and in self-employed participants. The group that fulfilled recommended PA levels (active) has higher levels of QoL in all domains except physical functioning. Conclusions: Almost one out of five low-income urban residents were physically inactive. In addition, individuals who attained recommended PA levels had better scores on some domains of HRQOL than those who did not. Our findings call for tailormade public health interventions to improve PA levels among the general population and particularly for low-income residents.

“…Quality of life was assessed using the Short Form of the Health the Survey Questionnaire (SF-12) developed by Ware, Kosinski, and Keller (1996) and translated into Korean by Han, Lee, Iwaya, Kataoka, and Kohzuki (2004). The validity and reliability of the Korean version of the SF-12 have been well established (Han et al, 2004;Kim et al, 2014). Higher scores on this scale indicate higher levels of quality of life.…”

Aims To examine the presence of symptom clusters and synergistic effects of symptom clusters on quality of life in rheumatoid arthritis patients. Background Rheumatoid arthritis patients frequently experience multiple concurrent symptoms of pain, fatigue, and depression. Design A nonexperimental, cross‐sectional correlation design. Methods The study participants were 179 rheumatoid arthritis patients. Data were collected between August and December 2016. A hypothetical model was developed based on the Theory of Unpleasant Symptoms Model: physiological antecedents included disease activity and obesity; symptoms of pain, fatigue, and depression were hypothesized as being clustered, and quality of life was taken as the outcome variable. Results Disease activity had significant direct effects on pain, fatigue, and depression and indirect effects on fatigue and depression, whereas obesity had a significant direct effect on fatigue alone. Three symptom clusters, namely, pain fatigue, fatigue depression, and pain‐fatigue depression were identified and found to have significant synergistic effects on quality of life. Conclusions Our findings support the importance of managing clusters of symptoms simultaneously, that is, collective symptom management. Inter‐cluster dynamics between symptoms should be considered when nurses develop symptom management strategies or self‐management programs to improve the quality of life of rheumatoid arthritis patients.
