This study compared the perceived social support of young and older adult cancer patients, examining possible influencing factors as well as associations with health-related quality of life. A total of 179 young patients (18–39 years) and 200 older adult patients (> 70 years) with haematological malignancies completed questionnaires on their perceived social support (ISSS-8, scales: Positive Support and Detrimental Interactions, range 0–16) and health-related quality of life (EORTC QLQ-C30). Tests for mean differences, correlations and regression analyses to determine associated variables of social support were performed. No difference was reported between young (M = 13.40, SD = 2.81) and older adult patients (M = 13.04, SD = 3.82; p = .313) for Positive Support. However, young patients (M = 4.16, SD = 3.10) reported having had more Detrimental Interactions than older patients did (M = 1.63, SD = 2.42; p < .001, Cohen’s d = .910). Comparison of the EORTC QLQ-C30 Function scales showed poorer outcomes for young patients on Emotional, Cognitive and Social Functions and a higher outcome on Physical Function compared with older adult patients. Regression analyses indicated that age (young vs. older adult patients) significantly explained proportions of variance in all models, with young age having a negative impact on Emotional, Cognitive and Social Functions and a positive impact on Physical and Role Functions compared with old age. Significant associations between Detrimental Interactions and all the scales examined except Cognitive Function were found. The difference in negative perceptions of social support in young vs. older adult patients and its impact on health-related quality of life emphasises the necessity of differentiating between positive and negative social support. Negative interactions should be addressed through psychosocial care, particularly with young cancer patients.

年轻人与老年人血液系统恶性肿瘤患者的感知社会支持以及与健康相关的生活质量的关联

这项研究比较了年轻和年长的成年癌症患者的感知社会支持，研究了可能的影响因素以及与健康相关的生活质量的关联。共有179名年轻（18-39岁）的血液病患者和200名年龄较大的血液系统恶性肿瘤（> 70岁）患者完成了关于他们所感知的社会支持的问卷调查（ISSS-8，量表：积极支持和有害相互作用，范围0-16）。与健康相关的生活质量（EORTC QLQ-C30）。进行了均值差异，相关性和回归分析的测试，以确定相关的社会支持变量。阳性支持的年轻患者（M = 13.40，SD = 2.81）和成年患者（M = 13.04，SD = 3.82； p = .313）之间没有差异。但是，年轻患者（M = 4.16，SD = 3。10）报告说比老年人患者具有更多的有害相互作用（M = 1.63，SD = 2.42; p <.001，Cohen's d = .910）。EORTC QLQ-C30功能量表的比较显示，与老年患者相比，年轻患者在情感，认知和社会功能方面的结局较差，在身体机能方面的结局较高。回归分析表明，年龄（年轻患者与成年患者）在所有模型中均能很好地解释方差的比例，与年龄相比，年轻人年龄对情感，认知和社会功能有负面影响，对身体和角色功能有积极影响。发现有害互动与除认知功能外的所有量表之间均存在显着关联。青少年对社会支持的负面看法差异 老年患者及其对健康相关生活质量的影响强调了区分正面和负面社会支持的必要性。负向互动应通过社会心理护理来解决，尤其是对于年轻的癌症患者。
