Measuring family caregivers' quality of life plays a significant role in improving the quality, efficiency, development, and provision of efficient services for patients with COVID-19. As a result, evaluating the quality of life requires the use of valid and reliable measures that are culturally appropriate. This study was conducted to determine the psychometric properties of the Persian version of the Quality of Life in Life-Threatening Illness-Family Carer Version (QOLLTI - F) in patients with COVID-19.
This methodological study was carried out in 2021 at Baqiyatallah Hospital in Tehran. After gaining approval from the tool creator, the translation was carried out utilizing the forward-backward approach. Cognitive interviews with 10 family caregivers of COVID-19 patients were used to demonstrate face validity. Moreover, construct validity was identified by performing exploratory factor analysis (EFA) ( = 251), confirmatory factor analysis (CFA) ( = 200), and convergent validation using Zarit Burden Interview (ZBI) questionnaire. For scale reliability, internal consistency and stability were performed using Cronbach's Alpha Coefficient and test-retest, respectively.
451 family caregivers of patients with COVID-19 were enrolled in this study. Three factors with a cumulative variance of 51.85% were extracted during EFA: (1) Caregiver's physical-emotional status, (2) Satisfaction with the situation, and (3) Caregiver's concerns. CFA showed that the model enjoyed a moderate to a good fit of information (RMSEA: 0.087; NFI: 0.98; CFI: 0.91; IFI: 0.91; GFI 0.89; standardized RMR: 0.070). A significant correlation was found between the Persian version of the ZBI and participants' total scores of QOLLTI - F v3 ( = -0.196, = 0.000). Cronbach's Alpha Coefficient = 0.719 and ICC stability reliability = 0.71 of the questionnaire were confirmed.
The Persian version of the QOLLTI - F v3 is a valid and reliable scale that can measure family caregivers' quality of life during a Life-Threatening illness in patients with COVID-19. This instrument may be utilized in clinical trials and research to enhance the quality of life for family carers in Iranian society.
评估家庭照顾者的生活质量对于提高为新冠肺炎患者提供的服务的质量、效率、发展及有效性具有重要意义。因此，评估生活质量需要使用有效、可靠且文化适宜的测量工具。本研究旨在确定新冠肺炎患者中波斯语版《危及生命疾病中的生活质量 - 家庭照顾者版》（QOLLTI - F）的心理测量特性。
本方法学研究于2021年在德黑兰的巴奇亚塔拉医院开展。在获得工具创建者的批准后，采用前后翻译法进行翻译。对10名新冠肺炎患者的家庭照顾者进行认知访谈以证明表面效度。此外，通过进行探索性因子分析（EFA）（n = 251）、验证性因子分析（CFA）（n = 200）以及使用扎里特负担访谈（ZBI）问卷进行收敛效度验证来确定结构效度。对于量表信度，分别使用克朗巴哈α系数和重测法进行内部一致性和稳定性分析。
本研究纳入了451名新冠肺炎患者的家庭照顾者。在探索性因子分析过程中提取了三个累计方差为51.85%的因子：（1）照顾者的身心状况，（2）对现状的满意度，（3）照顾者的担忧。验证性因子分析表明该模型对信息的拟合度为中等至良好（RMSEA：0.087；NFI：0.98；CFI：0.91；IFI：0.91；GFI 0.89；标准化RMR：0.070）。发现波斯语版ZBI与参与者的QOLLTI - F v3总分之间存在显著相关性（r = -0.196，p = 0.000）。问卷的克朗巴哈α系数 = 0.719，组内相关系数稳定性信度 = 0.71得到确认。
波斯语版QOLLTI - F v3是一个有效且可靠的量表，可用于测量新冠肺炎患者在危及生命疾病期间家庭照顾者的生活质量。该工具可用于临床试验和研究，以提高伊朗社会家庭照顾者的生活质量。
