People with dementia (PWD) may exhibit symptoms that negatively affect their relationships with their families or friends which could cause social strain. The Negative Relationship Quality (NRQ) questionnaire can be used to measure social strain in PWD. There has never been an Indonesian adaptation of the NRQ. This preliminary study aimed to measure the validity and reliability of the NRQ among PWD in Indonesia (NRQ-INA). This study used a cross-sectional design. Forward−backward translation methods were conducted first. Pearson’s correlation and factor analysis were employed for the validity test. Cronbach’s alpha and test−retest were used to determine reliability. The NRQ-INA has four parallel items related to social strain that are divided into three subscales and asked to spouse/partner, family members, and friends, leading to a total of 12 questions. The results of validity testing from 60 respondents showed that all items in the NRQ-INA were strongly valid with correlation coefficients (r) of >0.8 (p < 0.01). Factor analysis showed a convergence with the variance explained of more than 50% for all items in each subscale, which also indicated that NRQ-INA had acceptable construct validity to measure social strain. Cronbach’s alpha values (α) were 0.926, 0.942, and 0.938 for the subscales of spouse, friends, and family members, respectively. The correlations of test−retest reliability for all items were >0.7 (p < 0.01), demonstrating a reliable NRQ-INA measurement. In conclusion, NRQ-INA had a good validity and reliability to measure social strain in PWD. Further study of the concurrent validity among PWD is still needed.
患有痴呆症的人（PWD）可能会表现出一些症状，这些症状会对他们与家人或朋友的关系产生负面影响，进而可能导致社会压力。负面关系质量（NRQ）问卷可用于衡量PWD的社会压力。此前从未有过NRQ的印度尼西亚语版本。这项初步研究旨在评估印度尼西亚PWD群体中NRQ（NRQ-INA）的有效性和可靠性。本研究采用横断面设计。首先进行了前后翻译法。有效性检验采用皮尔逊相关性分析和因子分析。采用克朗巴赫α系数和重测法来确定可靠性。NRQ-INA有四个与社会压力相关的平行项目，分为三个子量表，分别向配偶/伴侣、家庭成员和朋友进行询问，共12个问题。60名受访者的有效性测试结果表明，NRQ-INA中的所有项目都具有很强的有效性，相关系数（r）>0.8（p<0.01）。因子分析表明，每个子量表中所有项目的方差解释率均超过50%，这也表明NRQ-INA在测量社会压力方面具有可接受的结构效度。配偶、朋友和家庭成员子量表的克朗巴赫α值（α）分别为0.926、0.942和0.938。所有项目的重测信度相关性均>0.7（p<0.01），表明NRQ-INA测量具有可靠性。总之，NRQ-INA在测量PWD社会压力方面具有良好的有效性和可靠性。仍需要对PWD群体的同时效度进行进一步研究。
