Enhancing the multi-dimensional assessment of quality of life: introducing the WHOQOL-Combi

Psychometric evaluation of the WHOQOL-BREF and its shorter versions for general Thai population: confirmatory factor analysis and Rasch analysis

PURPOSE

Rasch analysis was employed to validate the World Health Organization Quality of Life-BREF (WHOQOL-BREF) and its existing shorter versions in the general Thai population.

METHODS

1200 respondents were randomly selected to complete the questionnaire. Confirmatory factor analysis (CFA) was employed to test the structure of the WHOQOL-BREF and its shorter versions with the random sub-sample of 900 respondents, while Rasch analysis was performed with a random sub-sample of 300 respondents.

RESULTS

The CFA confirmed the factor structure of WHOQOL-BREF and its shorter versions. The Rasch analysis revealed that the WHOQOL-BREF, when a four-domain structure was tested using a subtest approach, achieved acceptable model fit to the Rasch model and met the expectations of unidimensionality with high reliability (PSI = 0.87). Individual domain models were also unidimensional, but reliability of the 3-item social domain was inadequate. While the 8-item EUROHIS-QOL-8 and 5-item WHOQOL-5 achieved an overall acceptable fit and met the expectations of unidimensionality, the reliability of the WHOQOL-5 was below the acceptable threshold (PSI = 0.66). Reliability of the EUROHIS-QOL-8 was satisfactory (PSI = 0.79).

CONCLUSIONS

The WHOQOL-BREF is a valid instrument for use in the Thai general population, both as a total score as well as individual subscales. Rasch analysis also supports the use of EUROHIS-QOL-8, but the WHOQOL-5 lacks good reliability. While the reliability of the EUROHIS-QOL-8 is sufficiently high for between-group analysis, the Thai WHOQOL-BREF total score can also be used for within-participant analyses. Rasch investigation with a more varied health conditions of general Thai samples or patient groups is encouraged for future studies.

Measuring population health and quality of life: Developing and testing of the significant quality of life measure (SigQOLM)

Quality of life (QOL) should ideally be determined by a broader spectrum of measurable parameters. This study aims to develop and validate a study instrument that is designed to determine a holistic measure of health and non-health aspects of QOL, and it is called the 'Significant Quality of Life Measure' (SigQOLM). This study involves five phases which aim to (i) explore and understand the subject matter content, (ii) develop a questionnaire, (iii) assess its content validity and face validity, (iv) conduct a pilot study, and lastly (v) perform a field-test by using the questionnaire. For the field-testing phase, a cross-sectional study was conducted which elicited responses from healthcare workers via a self-administered survey for all the SigQOLM items. Based on the results, the overall framework of the SigQOLM consists of four elements, 18 domains with 69 items. The element of "Health" is measured by nine domains, while "Relationships", "Functional activities, and "Survival" are measured by three domains respectively. The SigQOLM has been developed successfully and then validated with a high level of reliability, validity, and overall model fit. Therefore, the SigQOLM will provide researchers and policymakers another viable option to elicit a more comprehensive outcome measure of QOL which shall then enable them to implement specific interventions for improving the QOL of all the people, both healthy or otherwise.

What is the outcome of late-onset infected mesh removal after open tension-free inguinal hernioplasty: 3-year follow-up

PURPOSE

Reports of mesh infections following open tension-free inguinal hernioplasty are gradually increasing. Recent research has focused on identifying and managing mesh infections. However, studies examining the long-term outcomes and quality of life following mesh removal for late-onset infections are few. This study aimed to analyze the short and long-term outcomes after maximal removal of the implanted mesh in patients with late-onset mesh infection after open tension-free inguinal hernioplasty.

METHODS

Data of 105 patients who developed late-onset mesh infection after open tension-free inguinal hernioplasty and were admitted to our hospital from January 2014 to January 2019 were retrospectively analyzed. Patients were followed up by telephone or outpatient consultation for 3 years, focusing on hernia recurrence and mesh infection recurrence. Quality of life was assessed preoperatively and postoperatively using our developed scale; postoperative inguinal area pain was assessed using the visual analog score, and postoperative anxiety was assessed using the anxiety self-assessment scale.

RESULTS

Of the 105 patients who experienced late-onset mesh infection following open inguinal hernioplasty, 100 underwent mesh plug repair. The mean follow-up time was 58 months, and 10.5% (95/105) of the patients were lost to follow-up. Recurrence of infection was observed in 28.6% of patients (2/7) who underwent partial mesh removal and in 3.4% of patients (3/88) who underwent complete mesh removal. One inguinal hernia recurred 12 months after mesh removal (1.0% recurrence rate). In the third year following surgery as compared to the preoperative period, there were significant improvements in quality of life.

CONCLUSIONS

Hernia plugs may not be a good choice in tension-free inguinal hernia repair in view of the risk of late infections and fistulas. Remove all mesh at the time of the first operation for mesh infection. Hernia recurrence after late-onset infected mesh removal following open inguinal tension-free hernioplasty is rare. The post-operative quality of life, pain, and anxiety are gradually steadily improving.

Associations between perceived stress and quality of life in gynaecologic cancer patient-family caregiver dyads

PURPOSE

This study aims to explore the level of stress perceived and quality of life (QOL) by gynaecologic cancer (GC) patients and family caregivers' dyads.

METHODS

In this cross-sectional study, 86 dyads were recruited from the gynaecological oncology department of a general hospital in Taichung City, Taiwan. The patients and family caregivers completed a sociodemographic information sheet, the Perceived Stress Scale, and the Taiwanese version of World Health Organization Quality of Life-BREF questionnaire. Data were analysed using descriptive statistics and Pearson's correlations. This study used the actor-partner interdependence model (APIM) with distinguishable dyads to examine the effect of patients' and caregivers' perceived stress on QOL in patient-caregiver dyads.

RESULTS

GC patients' and caregivers' level of QOL was influenced by their own stress level (actor effect). Caregivers' stress was statistically negatively associated with the patients' QOL (partner effect); however, there were no partner effect from GC patients to caregivers. Both patients and family caregivers with higher perceived stress had poorer QOL. Therefore, we identified that stress has some level of actor and partner effects on QOL in GC patient-family caregiver dyads.

CONCLUSIONS

Family caregivers' stress displayed both actor and partner effects within the first year of the cancer diagnosis; therefore, patient-and caregiver-based interventions, such as stress reduction strategies, should be developed to enhance patients' and caregivers' QOL and stress management ability.

Validation of the multidimensional WHOQOL-OLD in Ghana: A study among population-based healthy adults in three ethnically different districts

OBJECTIVES

Study of well-being of older adults, a rapidly growing demographic group in sub-Saharan Africa, depends on well-validated tools like the WHOQOL-OLD. This scale has been tested on different populations with reasonable validity results but has limited application in Africa. The specific goal of this paper was to examine the factor structure of the WHOQOL-OLD translated into three Ghanaian languages: Ga, Akan, and Kasem. We also tested group invariance for sex and for type of community (distinguished by ethnicity/language).

METHODS

We interviewed 353 older adults aged 60 years and above, selected from three ethnically and linguistically different communities. Using a cross-sectional design, we used purpose and convenience methods to select participants in three geographically and ethnically distinct communities. Each community was made up of selected rural, peri-urban, and urban communities in Ghana. The questionnaire was translated into three languages and administered to each respondent.

RESULTS

The results showed moderate to high internal consistency coefficient and factorial validity for the scale. Using confirmatory factor analysis, we found that the results supported a multidimensional structure of the WHOQOL-OLD and that it did not differ for males and females, neither did it differ for different ethnic/linguistic groups.

CONCLUSIONS

We conclude that the translated versions of the measure are adequate tools for evaluation of quality of life of older adults among the respective ethnic groups studied in Ghana. These results will also enable comparison of quality of life between older adults in Ghana and in other cultures.
