“…The GQ includes six items such as, “I feel thankful for what I have received in life,” and “I sometimes feel grateful for the smallest things.” In the study by McCullough et al (2002) , confirmatory factor analyses (CFA) showed that a robust one-factor structure of the GQ existed, which was replicated in many other studies ( Froh et al, 2009 ; Yüksel and Oguz Duran, 2012 ; Caputo, 2016 ; Langer et al, 2016 ). Furthermore, McCullough et al (2002) found that the GQ was positively related to life satisfaction, affective well-being and prosocial traits, and negatively related to psychological symptoms and materialism.…”

“…Compared with the other two scales, the GQ has become the most widely used instrument for assessing dispositional gratitude in healthy populations, and is extensively used around the world. To our knowledge, the scale has been validated in many countries such as America, Italy, Chile, and Turkey ( Froh et al, 2011 ; Yüksel and Oguz Duran, 2012 ; Jans-Beken et al, 2015 ; Caputo, 2016 ; Langer et al, 2016 ). Therefore, the aim of the present research was validate the scale in a Chinese population.…”

“…However, to our knowledge, they only reported the internal consistency reliability of the Chinese GQ, and did not systematically test its psychometric properties such as factorial validity, which is important and necessary. For example, Langer et al (2016) found that item 6 (“Long amounts of time can go by before I feel grateful to something or someone”) was appropriate only in Chilean adults, rather than Chilean adolescents. Therefore, one aim of this study was to test the factorial validity and criterion-related validity in relation to subjective well-being of the Chinese version of the GQ in a large sample of Chinese adults.…”

The Gratitude Questionnaire (GQ; McCullough et al., 2002) is one of the most widely used instruments to assess dispositional gratitude. The purpose of this study was to validate a Chinese version of the GQ by examining internal consistency, factor structure, convergent validity, and measurement invariance across sex. A total of 1151 Chinese adults were recruited to complete the GQ, Positive Affect and Negative Affect Scales, and Satisfaction with Life Scale. Confirmatory factor analysis indicated that the original unidimensional model fitted well, which is in accordance with the findings in Western populations. Furthermore, the GQ had satisfactory composite reliability and criterion-related validity with measures of life satisfaction and affective well-being. Evidence of configural, metric and scalar invariance across sex was obtained. Tests of the latent mean differences found females had higher latent mean scores than males. These findings suggest that the Chinese version of GQ is a reliable and valid tool for measuring dispositional gratitude and can generally be utilized across sex in the Chinese context.

“…Clinical trials have demonstrated that evaluation of QOL and making changes leads to treatment improvement, increasing survival in cancer patients. 26 It has been shown that numerous disease processes associated with CoQ 10 deficiency can benefit from CoQ 10 supplementation, including cancer. In this study, we evaluated the efficacy of CoQ 10 on QOL in breast cancer patients.…”

Background: Survival rates among breast cancer patients and the number of patients living with treatment side effects have improved, leading to increased focus on quality of life (QOL). The objective of this study was to determine the efficacy of CoQ 10 on QOL scores among breast cancer patients in Iranian undergoing tamoxifen therapy. Methods: Thirty breast cancer patients were randomized into two groups. The first group received 100 mg CoQ 10 , and the second group took fplacebo once a day for 8 weeks. QOL was evaluated by a standard QOL questionnaire and a specific questionnaire on QOL of breast cancer patients at baseline and the end of the study. Also, physical activity of patients was assessed with the IPAQ questionnaire and dietary intake determined by a 3-day dietary record. Results: The data of 30 subjects were analyzed. According to QOL C30 data, CoQ 10 led to a significant increase in physical functioning (P=0.029), emotional functioning (P=0.031), and cognitive functioning (P=0.023) compared to placebo. Symptom scales revealed a notable reduction in appetite loss in the first group (P=0.01). Global health status showed no significant changes in either study arm. On the QOL BR23, progress in functions and decline in symptoms were not statistically significant. Arm symptoms showed significant reduction (P=0.022) in patients that received placebo. Conclusion: This trial indicates that CoQ 10 supplementation has effects in ameliorating some dimensions of QOL in breast cancer patients. To generalize the results, larger and longer intervention studies are needed. Clinical Trial Registration: IRCT2015042021874N1.

“…Following the steps outlined by Paap et al [ 14 ], we first established which domains of HRQL are most important to patients with COPD, using relevant literature (articles and existing questionnaires), as well as interviews with patients and HCPs [ 14 , 15 ]. Based on these findings, three generic domains/item banks from the PROMIS (Patient-Reported Outcomes Measurement Information System) framework were selected (fatigue, physical functioning, and ability to participate in social roles and activities) and a new COPD-specific domain/item bank (COPD-SIB) was developed [ 16 ]. This approach ensures comparability with other patient groups (generic domains), while providing additional sensitivity for measuring change within the specific patient group (disease-specific domain).…”

PurposeExamining item usage is an important step in evaluating the performance of a computerized adaptive test (CAT). We study item usage for a newly developed multidimensional CAT which draws items from three PROMIS domains, as well as a disease-specific one.MethodsThe multidimensional item bank used in the current study contained 194 items from four domains: the PROMIS domains fatigue, physical function, and ability to participate in social roles and activities, and a disease-specific domain (the COPD-SIB). The item bank was calibrated using the multidimensional graded response model and data of 795 patients with chronic obstructive pulmonary disease. To evaluate the item usage rates of all individual items in our item bank, CAT simulations were performed on responses generated based on a multivariate uniform distribution. The outcome variables included active bank size and item overuse (usage rate larger than the expected item usage rate).ResultsFor average θ-values, the overall active bank size was 9–10%; this number quickly increased as θ-values became more extreme. For values of −2 and +2, the overall active bank size equaled 39–40%. There was 78% overlap between overused items and active bank size for average θ-values. For more extreme θ-values, the overused items made up a much smaller part of the active bank size: here the overlap was only 35%.ConclusionsOur results strengthen the claim that relatively short item banks may suffice when using polytomous items (and no content constraints/exposure control mechanisms), especially when using MCAT.Electronic supplementary materialThe online version of this article (doi:10.1007/s11136-017-1624-3) contains supplementary material, which is available to authorized users.
