Family caregivers of psychiatric patients often experience various negative psychosocial consequences, with a decline in quality of life being the most prevalent. This study was conducted with the aim of evaluating the psychometric indices of the Persian version of the Family Caregiver-Specific Quality of Life Scale (FAMQOL).
This cross-sectional study was conducted in 400 family caregivers of patients with chronic psychiatric diseases in Iran in 2024 using convenience sampling. Using a forward-backward translation procedure, the face and content validity of the FAMQOL were assessed through both qualitative and quantitative methods. After face and content validity, in order to determine construct validity, exploratory (n = 200) and confirmatory (n = 200) factor analysis was performed. To determine reliability, internal consistency (Cronbach's alpha coefficient and Macdonald's omega coefficient) and stability (intraclass correlation coefficient) were estimated.
A total of 400 participants were evaluated, comprising 184 males (46.0%) and 216 females (54.0%). In content validity, one item was removed and during exploratory factor analysis, the remaining 15 items were loaded on four factors including social, spiritual, physical and psychological, which described 61.74% of the total variance. Confirmatory factor analysis showed that the obtained model has a good fit. All obtained factors had convergent and discriminant validity. Cronbach's alpha (0.783 to 0.932), Macdonald's omega (0.817 to 0.934) and intraclass correlation coefficients (0.953 to 0.971) showed acceptable internal consistency and stability of the factors of the Persian version of FAMQOL.
Findings from this study confirm that the Persian version of the FAMQOL is a valid and reliable instrument for evaluating the quality of life among family caregivers of patients with chronic psychiatric disorders. This scale holds significant potential for both research and clinical applications, facilitating the identification of caregivers' needs and guiding the creation of targeted interventions to enhance their quality of life.
精神科患者的家庭照顾者常常会经历各种负面的心理社会后果，其中生活质量下降最为普遍。本研究旨在评估《家庭照顾者特定生活质量量表》（FAMQOL）波斯语版本的心理测量指标。
本横断面研究于2024年在伊朗采用便利抽样法，对400名慢性精神疾病患者的家庭照顾者进行。通过前后翻译程序，采用定性和定量方法评估FAMQOL的表面效度和内容效度。在表面效度和内容效度之后，为了确定结构效度，进行了探索性（n = 200）和验证性（n = 200）因素分析。为了确定信度，估计了内部一致性（克朗巴哈α系数和麦克唐纳ω系数）和稳定性（组内相关系数）。
共评估了400名参与者，其中男性184名（46.0%），女性216名（54.0%）。在内容效度方面，删除了一个项目，在探索性因素分析中，其余15个项目加载在包括社会、精神、身体和心理在内 的四个因素上，这四个因素解释了总方差的61.74%。验证性因素分析表明，所获得的模型拟合良好。所有获得的因素都具有收敛效度和区分效度。克朗巴哈α系数（0.783至0.932）、麦克唐纳ω系数（0.817至0.934）和组内相关系数（0.953至0.971）表明，FAMQOL波斯语版本各因素具有可接受的内部一致性和稳定性。
本研究结果证实，FAMQOL波斯语版本是评估慢性精神疾病患者家庭照顾者生活质量的有效且可靠的工具。该量表在研究和临床应用方面都具有巨大潜力，可以帮助识别照顾者的需求，并指导制定有针对性的干预措施以提高他们的生活质量。
