St George's Respiratory Questionnaire

Tuberculosis (TB) is one of the disease as the highest contributor to the disease burden in Indonesia. Tuberculosis can affect the patients’ quality of life, such as psychological, physical, and social functioning. St. George's Respiratory Questionnaire (SGRQ) is a special instrument which was widely used to measure the patients’ quality of life with respiratory disease. The objective of this study was to validate the Indonesian version of the SGRQ as instrument to collect data. A descriptive cross section design with 61 subjects was conducted at the Pulmonary Clinics and Primary Health Centers in the region of Yogyakarta within 3 months. The validation process included the known group validity, convergent and discriminant validity and factor analysis. There were 14 items question numbers which did not meet the criteria for convergent validity and 9 items which did not meet the criteria for discriminant validity. Known group validity analysis on gender showed that of the three domains of SGRQ, the activity domain gave statistically significant result. The factor analysis showed the result of Kaiser Meyer Olkin analysis (KMO) was less than 0.5. With a few modifications, the Indonesian version of SGRQ is valid and reliable for measuring quality of life in tuberculosis patients.

Abstract Background and Objective: There is no comprehensive instrument for the assessment of postpartum quality of life (QOL). This study was conducted to develop the Maternal Postpartum Quality of Life Instrument (MPQOLI) and assess its psychometric properties.Materials and Methods: This methodological study was conducted in 2019–2020 using an exploratory sequential mixed-method design. A qualitative study and a literature review were conducted to generate MPQOLI items. Through purposeful sampling, 590 postpartum women were recruited to respond the instrument. Face and content validity were assessed qualitatively and quantitatively and construct validity was assessed through exploratory and confirmatory factor analyses and convergent and discriminant validity assessments. Reliability was also assessed through different methods, including Cronbach’s alpha and McDonald’s Omega.Results: Eight items were deleted in content validity assessments and eighteen items were deleted in item analysis. Participants responded the 31-item MPQOLI. During exploratory factor analysis, fifteen items were deleted and the remaining sixteen items were loaded on five factors labeled perceived support, sexual relationship, bonding with newborn, breastfeeding and newborn care, and satisfaction with postpartum transition. These five factors explained 53.26% of the total variance. Confirmatory factor analysis confirmed the five-factor structure of MPQOLI with a CMIN/DF of 2.192, an RMSEA of 0.057, a χ2 of 206.087, a PCFI of 0.738, a PNFI of 0.705, a CFI of 0.942, and an IFI of 0.943. Average variance extracted was more than 0.5 and more than maximum shared squared variance, confirming convergent and discriminant validity, respectively. Reliability was also confirmed with Cronbach’s alpha values of 0.70–0.907 and an intraclass correlation coefficient of 0.919.Conclusion: The sixteen-item MPQOLI is a valid and reliable instrument for postpartum QOL assessment. It includes items on the different aspects of postpartum QOL and can be used for the early diagnosis of impaired postpartum QOL. Further studies are needed to assess the psychometric properties of MPQOLI in different cultures and communities.

The aim of the study is to determine the reliability and validity of the Greek version of the Food Allergy Quality of life Questionnaire- Child Form (FAQLQ-CF). After linguistic validation, the Greek FAQLQCF, Food Allergy Independent Measure (FAIM) and Pediatric Quality of Life Inventory (PedsQL™) were used by a physician to interview children diagnosed with food allergy and aged 8-12 via telephone. Cronbach’s alpha was used to evaluate reliability, and factor analysis to assess construct validity. The correlation between FAQLQ-CF and FAIM was moderate (rho=0.509, P<0.001) and internal consistency was strong (Cronbach’s alpha 0.905). FAQLQ-CF discriminated well each question’s contribution to children’s quality of life deterioration (32- 80%), each child’s quality of life (17-89%), children differing in doing things with others (total score 3.55 vs 2.57, difference =0.98 > minimal clinical importance difference = 0.5; P<0.001), but not children differing in reporting anaphylaxis. The total FAQLQ-CF score correlated with the total PedsQL™ score and with the score of one of PedsQL™ subscales, demonstrating convergent validity. Factor analysis uncovered an underlying structure of four factors, explaining 50% of the variance. We can conclude that Greek FAQLQ-CF is a reliable, valid, discriminant tool for interviewing food allergic children aged 8- 12, detecting those in need for immediate care.

Purpose: Psychological well-being and health are closely linked at older ages. It is widely recognized that adapted regular physical exercise improves drastically both the physical and emotional well-being and allows older adults to stay healthy longer, with a better quality of life. In the framework of a European project (MOTION) to increase the life expectancy, independence and quality of life of older adults, the aim of the current research was to develop and validate a brief, multi-faceted, self-report measure of well-being in older adults. Method: The aim of Study 1 was to establish the factor structure of the newly developed measure using Exploratory Factor Analysis (EFA). The aim of Study 2 was to replicate the measure's factor structure using Confirmatory Factor Analysis (CFA), and to evaluate test-retest reliability and convergent validity. Results: Analyses allowed generating a model of well-being comprising four dimensions: Perceived physical value, self-esteem and self-efficacy, socialization, and emotional reactions. Conclusion: The findings suggest that the SMWQ is appropriate for use with older adults and can help researchers and health professionals to assess the effects of APA programs.

ABSTRACT Objective To evaluate the psychometric properties of the seven theoretical models proposed in the literature for European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30), when applied to a sample of Brazilian cancer patients. Methods Content and construct validity (factorial, convergent, discriminant) were estimated. Confirmatory factor analysis was performed. Convergent validity was analyzed using the average variance extracted. Discriminant validity was analyzed using correlational analysis. Internal consistency and composite reliability were used to assess the reliability of instrument. Results A total of 1,020 cancer patients participated. The mean age was 53.3±13.0 years, and 62% were female. All models showed adequate factorial validity for the study sample. Convergent and discriminant validities and the reliability were compromised in all of the models for all of the single items referring to symptoms, as well as for the “physical function” and “cognitive function” factors. Conclusion All theoretical models assessed in this study presented adequate factorial validity when applied to Brazilian cancer patients. The choice of the best model for use in research and/or clinical protocols should be centered on the purpose and underlying theory of each model.

This methodological study aimed to adapt the Neuropathy - and Foot Ulcer - Specific Quality of Life instrument - NeuroQol to Brazilian Portuguese and to analyze its psychometric properties. Participants were 50 people with peripheral diabetic neuropathy and foot ulcers. The floor and ceiling effects, the convergent and discriminant validity and the reliability were analyzed. The Cronbach’s alpha coefficient was used to test the reliability and the Pearson’s correlation coefficient to estimate the convergent validity, the Student’s t test was used to evaluate the discriminant validity in the comparison of the NeuroQol scores between participants with and without ulcers. Floor and ceiling effects were found in some domains of the NeuroQol. The reliability was satisfactory. The correlations between the domains of the NeuroQol and the SF-36 were negative, significant and of moderate to strong magnitude. The findings show that the Brazilian version of the NeuroQol is reliable and valid and may be employed as a useful tool for improving nursing care for people with DM.

The Impact

The Prolapse Quality of Life Questionnaire (P-QoL) is a specific questionnaire created to assess the impact of pelvic organ prolapse on women’s quality of life. The aim of the present study was to cross-culturally adapt and assess the psychometric properties of the P-QoL for Spanish women. The cross-cultural adaptation was conducted by a standardized translation/back-translation method. Psychometric analysis was performed by assessing the validity, reliability, responsiveness and feasibility. A total of 200 Spanish women were recruited and assigned to symptomatic and asymptomatic groups. The Spanish P-QoL version demonstrated good content validity. Convergent validity showed high intercorrelations with the Pelvic Floor Distress Inventory short form and the Pelvic Floor Impact Questionnaire short form. The discriminant validity showed statistically significant differences between the symptomatic and the asymptomatic groups. The internal consistency was high and of acceptable values. The test-retest reliability was shown to be high in all the cases. Regarding responsiveness, the effect size and standardized response mean demonstrated moderate values. The average time for administration was 10 (3) min. The Spanish P-QoL showed considerable support for the appropriate metric properties of validity, reliability, responsiveness and feasibility to evaluate the symptom severity and its impact on the quality of life in Spanish women with urogenital prolapse.
