BACKGROUND/AIM: A scale for behavioural pain assessment is useful for the detection and determination of pain in the elderly with dementia. This study aimed to translate and evaluate the psychometric properties of Doloplus-2 in the elderly with dementia in Iran.
In this methodological study, after translation and evaluating the face and content validity of Doloplus-2, 100 elderly people were selected by the convenience sampling method in Kashan, 2018–2019. Exploratory factor analysis, convergent validity, and known-groups comparison were applied to determine construct validity. Reliability was also assessed through internal consistency, equivalence, and stability methods were used. The ceiling and floor effects were also examined. Data were analyzed using the SPSS-v16 and via Mann-Whitney U test, Cronbach’s alpha, Spearman-Brown, and intraclass correlation coefficient (ICC).
The scale’s content validity index was 0.95%, and the item impact of each item was above 1.5. Factor analysis identified 2 “social- functional” and “conventional subjective-objective” factors in scale that altogether were able to explain 76% of the total variance. The results revealed that P-Doloplus-2 could discriminate between the 2 groups of elderly with and without known chronic painful diseases (P < 0.0001). There was a significant positive correlation between P-Doloplus-2 and PACSLAC-II-IR scores (r = 0.878, P < 0.0001). Cronbach’s alpha, ICC, and standard error of measurement for the scale were 0.950, 0.864, and ± 1.759, respectively. The frequency of minimum and maximum possible score of scale was less than 15%.
The Persian version of Doloplus-2 can be considered as a valid and reliable scale for pain assessment in the elderly with dementia.
背景/目的：行为疼痛评估量表可用于检测和确定痴呆老年人的疼痛。本研究旨在翻译并评估 Doloplus-2 在伊朗痴呆老年人中的心理测量学特性。
在这项方法学研究中，在翻译和评估了 Doloplus-2 的表面和内容效度后，2018-2019 年通过便利抽样法在卡尚选择了 100 名老年人。应用探索性因子分析、收敛效度和已知群体比较来确定结构效度。还通过内部一致性、等效性和稳定性方法评估了可靠性。还检查了天花板和地板效应。使用 SPSS-v16 分析数据，并通过 Mann-Whitney U 检验、Cronbach’s alpha、Spearman-Brown 和组内相关系数（ICC）进行分析。
该量表的内容效度指数为 0.95%，每个项目的项目影响均大于 1.5。因子分析确定了量表中的 2 个“社会-功能”和“传统主观-客观”因子，总共能够解释总方差的 76%。结果表明，P-Doloplus-2 能够区分有和无已知慢性疼痛疾病的 2 组老年人（P < 0.0001）。P-Doloplus-2 与 PACSLAC-II-IR 评分之间存在显著正相关（r = 0.878，P < 0.0001）。该量表的 Cronbach’s alpha、ICC 和测量标准误差分别为 0.950、0.864 和 ± 1.759。量表的最小和最大可能评分的频率均小于 15%。
Doloplus-2 的波斯语版本可被视为评估痴呆老年人疼痛的有效且可靠的量表。
