Adaptation and psychometric testing of the hoarding rating scale (HRS): a self-administered screening scale for epidemiological study in Chinese population

Abstract

Background: Hoarding disorder is a chronic and debilitating illness associated with restrictions on activities of daily living, compromised social and occupational functioning, and adverse health outcomes. However, researchers lack a brief and self-administered screening measurement to assess compulsive hoarding in the Chinese speaking population. This study aimed to adapt and validate the Hoarding Rating Scale-Interview (HRS-I) to as a tool for screening compulsive hoarding behavior in Chinese population. Methods: This study comprised two phases. During Phase 1, the English-language HRS-I was translated into Chinese (CHRS) (comprehensible for most Chinese speaking population, e.g., Cantonese & Mandarin) and subjected to an equivalence check. In Phase 2, the CHRS was validated by examining internal consistency, stability, and construct validity. Different samples were used appropriately to verify the items and reflect the psychometric properties. Results: In Phase 1, the CHRS yielded satisfactory content (S-CVI = 0.93) and face validity ratings (comprehensibility = 100%, N = 20 participants of general public with age 18-72) and the English and Chinese versions were found to be equivalent (ICC = 0.887; N = 60 university staff and students). Phase 2 revealed satisfactory levels of internal consistency (Cronbach's α = 0.86; corrected item-total correlation = 0.60-0.74; N = 820 participants of general public), 2-week test-retest reliability (ICC = 0.78; N = 60 university students), and construct validity (onefactor CFA solution matched with the hypothesized model, χ 2 /d.f. = 2.26, RMSEA = 0.049, CFI = 0.99, IFI = 0.99, NFI = 0.99; n = 520 participants of general public). Conclusions: This study provides sufficient evidence of the reliability and validity of the CHRS for compulsive hoarding behavior screening in the Chinese population through self-administered method.

Adaptation of Hoarding Rating Scale Interview in Urdu for Use in Pakistan

“…Validity estimates of the scale as measured by the correlation between HRS-I and other measures were also found to be in acceptable range. These results are consistent with previous studies 13,14,15 on adaptation of hoarding rating scale interview.…”

The Association Between Physical and Mental Health and Face Mask Use During the COVID-19 Pandemic: A Comparison of Two Countries With Different Views and Practices

“…The Chinese respondents had significantly higher IES-R scores than Poles. It is important to note that the Cronbach’s alpha value of Chinese version of IES-R was higher than 0.90 and it might suggest redundancy of items ( 41 , 42 ).…”

“…The Chinese respondents had significantly higher IES-R scores than Poles. It is important to note that the Cronbach's alpha value of Chinese version of IES-R was higher than 0.90 and it might suggest redundancy of items (41,42). Prior to the COVID-19 pandemic, the two countries had similar age standardized prevalence of depression and anxiety (18).…”

The Relationship Between Compulsive Buying and Hoarding in China: A Multicenter Study

“…CHRS has been used in a large-scale population survey (N = 1028) (Li, 2017). Based on the data, the reliability of CHRS was satisfactory (Cronbach's α = 0.86, corrected item-total correlation coefficients = 0.60-0.74, intraclass correlation coefficient of 2-week test-retest reliability = 0.78) (Liu et al, 2020). The content validity (Content Validity Index (CVI) = 0.80-1.00, ratings from six healthcare and social science experts in compulsive behaviors), face validity (100% comprehensibility from 20 public samples), and construct validity (verified by the exploratory and confirmatory factor analyses) were satisfactory (Liu et al, 2020).…”
