Evaluation of the psychometric properties and the clinical feasibility of a Chinese version of the Doloplus-2 scale among cognitively impaired older people with communication difficulty

Validation of a Causal Model of Agitation Among Institutionalized Residents With Dementia in Taiwan

“…Each item is rated on a four-point scale ranging from 0 to 3, with higher scores indicating more serious pain symptoms; total scores !5 indicate the presence of pain (Lafebvre-Chapiro & Doloplus group, 2001). The reliability of the Doloplus-2 Scale has been demonstrated by previous studies in French and Chinese populations (Chen, Lin, & Watson, 2010). The internal consistency of the French version of the Doloplus-2 Scale was a ¼ .84, and the concurrent validity was demonstrated by significant correlations between the F-Doloplus-2 Scale and the Visual Analog Scale (VAS; r ¼ .46; Pautex et al, 2007).…”

“…The internal consistency of the French version of the Doloplus‐2 Scale was α = .84, and the concurrent validity was demonstrated by significant correlations between the F‐Doloplus‐2 Scale and the Visual Analog Scale (VAS; r = .46; Pautex et al, ). In Taiwan, the internal consistency of the Chinese version of the Doloplus‐2 Scale ranges from α = .67 to 0.87, and the construct validity was confirmed by factor analysis, in which 65% of the variance in total score explained by three factors (Chen et al, ). For this study, the internal consistency was α = .73.…”

Validation of Doloplus-2 among nonverbal nursing home patients - an evaluation of Doloplus-2 in a clinical setting

“…Another study estimating internal consistency in 501 older adults from centres participating in the Doloplus Group [22] found a Cronbach's alpha of 0.82 for the total scale. Chen et al [34] found a Cronbach's alpha between 0.67 (psychosocial reaction subscale) and 0.87 (psychomotor reactions subscale) on the different subscale. The Cronbach's alpha for the total scale was 0.74 [34].…”

Assessing measurement in health: Beyond reliability and validity

“…In the assessments of inter-rater reliability, intraclass correlation coefficients were computed in only one of three studies with continuous scores (Chen, Lin, & Watson, 2010); the other two papers relied on correlation coefficients. In the one paper with Two parameters of measurement error can be estimated.…”
