Psychometric Evaluation of the Brunei-Malay SF-36 version 2 Health Survey

Health-related quality of life in Chinese medical staff: a latent profile analysis

Objective

To investigate subgroups of health-related quality of life (HRQoL) in the Chinese medical staff and identify the demographic factors associated with these profiles.

Methods

574 Chinese medical staff were surveyed online. HRQoL was measured by using the 36-Item Short Form Health Survey, Version 2. Latent profile analysis (LPA) was used to identify the profiles of HRQoL. The associations between HRQoL profiles and covariates were assessed using multinomial logistic regression.

Results

Three HRQoL profiles were developed: low HRQoL at 15.6%, moderate HRQoL at 46.9%, and high HRQoL at 37.6%. Multinomial logistic regression showed night shift times, aerobic exercise conditioning, and personality type significantly predicted the profile membership.

Conclusion

Our findings develop earlier approaches that only used total scores to evaluate this group's HRQoL and help them with tailored interventions to promote better HRQoL.

Improvement of health-related quality of life and psychological well-being after HCV eradication with direct-acting antiviral agents. Real life setting data of an Italian cohort valued by Hepatitis Quality of Life Questionnaire (HQLQv2)

HCV (Hepatitis C Virus) decreases Health-Related Quality of Life with detriments to physical, mental and social health domains. Interferon and Ribavirin treatment is associated with depression and anxiety that further impairs HRQoL (Health- Related Quality of Life). IFN-free (interferon-free) regimes (Direct Acting Antivirals, DAAs) are safe and highly effective drugs, with improvement also of HRQoL and related Psychological Well-Being. Our aim is to describe how the latest generation IFN-free treatment can change quality of life and related Psychological Well-Being in Italian Chronic Hepatitis C/Cirrhosis affected patients. SF-36v2 (Short Form Health Survey is a 36-item, patient-reported survey of patient health) – HQLQv2 (Hepatitis Quality of Life Questionnaire) was administered at two time points: baseline (n=72) and 12 weeks after the end of therapy [n=72, SVR=72 - Sustained Virologic Response (SVR)]. Patients with chronic HCV undergoing DAAs treatment from two Italian centers were enrolled. The overall average of the answers is configured for most of the domains that make up the questionnaire, with scores above 50. The quality of life of this sample is very close to the average of the US population, with a minimum average score of 45.9 for the Role Emotional scale and an average maximum score of 56.4 for the Vitality scale. Both are significant results from statistical analysis. It seems that DAAs treatment therapy does not affect but improves the general quality and psychological state of adult patients with Chronic HCV infection.

What is the Quality of Life of Transtibial Amputees in Brunei Darussalam?

Introduction:

Lower limb amputations have a profound impact on the quality of life (QoL) of the patients. This study was done to assess the QoL of patients with transtibial (below-the-knee) amputations (TTA) and transtibial amputees fitted with prosthesis.

Material and Methods:

A case-control study of patients who had undergone TTA from 2015 to 2018 was conducted in Raja Isteri Pengiran Anak Saleha Hospital (RIPAS). Complete data was available for 30 subjects and it was compared with 30 diabetic, non-amputee patients matched for age and gender. QoL was assessed using the RAND 36-Item Health Survey (SF-36) and the functional outcome of prosthesis-fitted transtibial amputees was assessed using the Houghton Scale.

Results:

Almost all cases of TTA were a result of vascular problems related to diabetes and chronic renal disease (n=29; 97%). Eighteen (60%) participants were fitted with prosthesis and 15 (50%) reported having phantom pain. QoL of participants was found to be significantly lower than that of age and sex-matched diabetic non-amputees with regards to physical functioning, role limitation due to physical health, emotional well-being, social functioning, and bodily pain. The mean Houghton Score for participants fitted with prosthesis was 4.89 (SD= 2.83) suggesting low functional outcome.

Conclusion:

TTA has a negative impact on the QoL of patients, especially in terms of functionality. The availability of prosthesis does not significantly improve the quality of life except in the physical functioning domain. Emotional well-being should be emphasised more in the rehabilitation process as this study found poor emotional well-being among participants.

Verification of the Reliability and Validity of the Short Form 36 Scale in Indonesian Middle-aged and Older Adults

Objectives

The Short Form 36 (SF-36) questionnaire is increasingly being used to measure health-related quality of life (HRQoL) in Indonesia. However, evidence that it is valid for use in Indonesian adults is lacking. This study assessed the validity and reliability of the SF-36 in Indonesian middle-aged and older adults.

Methods

Adults aged 46-81 years (n=206) in Yogyakarta, Indonesia completed the SF-36, another measure of HRQoL (the EuroQoL visual analogue scale [EQ-VAS]), and measures assessing their demographic characteristics. Fifty-four percent (n=121) completed the SF-36 measure again 1 week later. Confirmatory factor analysis was conducted to confirm the factor structure of the SF-36. Internal consistency reliability was estimated using Cronbach’s alpha, and test-retest reliability was assessed using intraclass correlations. Convergent and discriminant validity were assessed by computing correlations among SF-36 subscales, between subscales and the 2 component scores, and between component scores and EQ-VAS scores.

Results

Most scaling assumptions were met. The hypothetical factor structure fit the data poorly (root mean square error of approximation [RMSEA]=0.108) and modification was required for a good fit (RMSEA=0.060). Scores on all subscales demonstrated acceptable internal consistency (α>0.70) and test-retest reliability (r>0.70). Divergent validity was supported by weak to moderate interscale correlations (r=0.19 to 0.64). As expected, the 2 summary scores were moderately to strongly correlated with the EQ-VAS (r>0.60).

Conclusions

The findings adequately support the use of SF-36 in Indonesian middle-aged and older adults, although the optimal algorithm for computing component scores in Indonesia warrants further investigation.
