Psychometric properties of the Korean version of the medical outcomes study HIV health survey: results from a multicenter survey in Korea

Abstract

BackgroundPrecise assessment of health-related quality of life (HRQOL) with a reliable and valid measure is a prerequisite to the enhancement of HRQOL. This study examined the psychometric properties of the Korean version of the Medical Outcomes Study HIV Health Survey (K-MOS-HIV).MethodsThe reliability and validity of the K-MOS-HIV were examined in a multicenter survey involving 201 outpatients with human immunodeficiency virus (HIV)/ acquired immunodeficiency syndrome (AIDS) from four teaching hospitals throughout Korea.ResultsCeiling effects were observed in six subscales scores, particularly, for the role functioning (71.1%), social functioning (63.2%), and pain (48.8%) scores. The Cronbach’s α for the physical health summary and mental health summary were 0.90 and 0.94, respectively, and it ranged from 0.78 to 0.95 for the subscales. The results of the exploratory structural equation modeling supported the two-factor structure of the K-MOS-HIV (physical health summary and mental health summary). An examination of the mean square statistics values from the Rasch analysis showed that the information-weighted fit and outlier-sensitive fit statistics were within the acceptable ranges of 0.6–1.4 except for two items in the mental health summary. The convergent validity of the K-MOS-HIV was supported by its significant positive correlations with the World Health Organization Quality of Life-HIV-BREF subscale scores. Its known-group validity was proven with its ability to detect significant differences in several K-MOS-HIV subscale scores among participants with different sociodemographic and clinical characteristics.ConclusionsThe K-MOS-HIV health survey appears to be a reliable and valid measure of HRQOL.

Psychometric properties of self-reported measures of health-related quality of life in people living with HIV: a systematic review

“…Fifteen PROMs were rated as insufficient (-) for content validity [ 11 , 17 , 48 , 49 , 53 , 57 , 59 – 61 , 77 – 82 ]. There were 19 PROMs [ 19 , 24 , 26 , 37 – 40 , 45 , 51 – 54 , 57 , 59 , 60 , 64 , 70 , 74 , 75 ] rated as sufficient (+) for construct validity, and 31 [ 10 – 12 , 14 – 17 , 21 , 34 – 36 , 41 , 42 , 44 , 46 – 48 , 50 , 53 , 55 , 56 , 58 , 59 , 67 , 68 , 76 – 79 , 81 , 82 ] were rated as insufficient (−). The internal consistency was rated as sufficient (+) for 59 PROMs [ 9 – 19 , 22 – 25 , 34 , 36 – 49 , 51 – 72 , 74 , 76 – 82 ] and as insufficient (−) for 4 PROMs [ 20 , 21 , 35 , 50 ].…”

“…The reliability and validity of the instrument were likely to decrease in the different translated versions due to their cultural adjustment. For these versions, mixed findings on the hypothesis testing of the MOS-HIV were reported [34][35][36][37][38][39][40][41][42][43][44][45][46][47]. As data on the psychometric properties of many studies were missing or indeterminate, we can draw only preliminary conclusions.…”

“…Five PROMs were strongly recommended based on the methodological quality of each psychometric property, including MOS-HIV, WHOQoL-HIV-BREF, SF-36, MQoL-HIV, and WHOQoL-HIV. Among the seven language versions of the MOS-HIV [21,[34][35][36][37][38][39][40][41][42][43][44][45][46][47], six were rated as "high" for internal consistency [21,34,35,[41][42][43][44][45][46][47], and one was rated as "moderate" [36][37][38][39][40]. There were three versions rated as "high" for cross-cultural validity/translation [34,41,44,46].…”

The Medical Outcome Study‐HIV Health Survey: A systematic review and reliability generalization meta‐analysis

“…The MOS‐HIV has been widely applied in both clinical practice and research studies (Cooper et al, 2017). In effect, it has been published in different cultures and languages such as Chinese (Huang, Tian, Dai, & Ye, 2013), Dutch, Italian, German, French, UK English (Scott‐Lennox, Wu, Boyer, & Ware, 1999), Korean (Shim et al, 2018), Greek (Stasinopoulou et al, 2010), Persian (Alamolhoda, Jafari, Ayatollahi, & Kazerooni, 2017) and Spanish (Badia, Podzamczer, Garcia, & Consiglio, 1999), showing good psychometric properties. Most studies that have applied the MOS‐HIV have reported good internal consistency for the total scale and also for the subscales (coefficients α higher than .70; Burgess, Dayer, Catalan, Hawkins, & Gazzard, 1993; Revicki, Sorensen, & Wu, 1998; Revicki, Swartz, Wu, Haubrich, & Collier, 1999; Revicki, Wu, & Murray, 1995; Safrin et al, 1996; Wu et al, 1997).…”
