One of the key psychosocial factors that impact mental and emotional health is social support. While much research has been conducted on the role of social support in the lives of cancer patients, there is a lack of studies that consider populations who need specific tools to assess this concept.
The aim of this study was to evaluate the psychometric properties of the MOS Social Support Scale (1991) in 499 Peruvian cancer patients between the ages of 18 and 87 (M= 46.30, SD = 15.747).
In this study, three models of the MOS were analyzed based on 19-item versions (four factor, second order and bifactor model).
The results showed a better psychometric fit in the 19-item bifactor model with optimal fit indices through the structural equation method (SB-χ2/df = 1.94, CFI = 0.966, TLI= 0.955, SRMR = 0.038 and RMSEA = 0.058). Additionally, there was evidence of configural, metric and scalar invariance with this instrument according to the gender of the surveyed cancer patients. Convergent validity using a network analysis approach revealed positive associations between social support dimensions and quality of life.
Emotional support and positive interactions dimensions were found to be important interconnections in the overall network, as indicated by their greater centralities. Therefore, this instrument could be suggested as a reliable way to evaluate cancer patients and their perceived support.
影响心理和情绪健康的关键社会心理因素之一是社会支持。虽然已经对社会支持在癌症患者生活中的作用进行了大量研究，但缺乏针对需要特定工具来评估这一概念的人群的研究。
本研究旨在评估499名年龄在18至87岁之间（M = 46.30，SD = 15.747）的秘鲁癌症患者中，医学结局研究社会支持量表（1991年版）的心理测量特性。
在本研究中，基于19个条目的版本（四因素模型、二阶模型和双因素模型）对医学结局研究量表的三种模型进行了分析。
结果表明，通过结构方程法，19个条目双因素模型的心理测量拟合度更好，具有最佳拟合指数（SB-χ2/df = 1.94，CFI = 0.966，TLI = 0.955，SRMR = 0.038，RMSEA = 0.058）。此外，根据接受调查的癌症患者的性别，该工具存在构型不变性、度量不变性和标量不变性的证据。使用网络分析方法的收敛效度揭示了社会支持维度与生活质量之间的正相关关系。
情感支持和积极互动维度在整个网络中被发现是重要的相互联系，这体现在它们更高的中心性上。因此，可以建议将该工具作为评估癌症患者及其感知支持的可靠方法。
