The aim of this longitudinal study was to examine the consistency of health-related quality of life (HRQoL) among people living with HIV (PLWH) by breaking down the variance of repeated HRQoL measures into trait, state, and method components and to test the stability of HRQoL over time. In addition, we wanted to examine whether HRQoL trait components are related to personality traits, while controlling for selected socio-medical variables.
Three assessments were performed with a six-month lag on each assessment. Each participant filled out a World Health Organization (WHO) Quality of Life-BREF to assess HRQoL and a NEO-FFI to measure Big Five personality traits. Overall, 82 participants out of 141 (58.2% of the initial sample) participated in all the assessments.
The HRQoL among PLWH represented a stable trait to a somewhat greater extent than a situational variability, although the proportions were domain and time variant. More specifically, psychological domain appeared to be the most consistent, whereas social domain appeared to be the most prone to situational influences. The trait component of HRQoL was positively related to being in a relationship, being employed, and being extraverted, and negatively related to neuroticism, which altogether explained 26% of the trait variance.
HRQoL among PLWH is rather distinct from personality and socio-medical data, which indicates its uniqueness in a clinical practise. Thus, there is a need for a more comprehensive assessment of HRQoL among this patient group to capture an additional source of variance in this important theoretical construct.
本纵向研究旨在通过将重复的 HRQoL 测量的方差分解为特质、状态和方法成分，来检验 HIV 感染者（PLWH）的健康相关生活质量（HRQoL）的一致性，并测试 HRQoL 随时间的稳定性。此外，我们还想检验 HRQoL 特质成分是否与人格特质相关，同时控制选定的社会医学变量。
在每次评估之间间隔六个月进行了三次评估。每位参与者都填写了一份世界卫生组织（WHO）生活质量简表（WHOQOL-BREF）来评估 HRQoL，以及一份大五人格量表（NEO-FFI）来测量大五人格特质。总共，在 141 名参与者中，有 82 名（初始样本的 58.2%）参加了所有评估。
PLWH 的 HRQoL 在某种程度上比情境变异性更能代表稳定的特质，尽管比例因领域和时间而异。更具体地说，心理领域似乎是最一致的，而社会领域似乎最容易受到情境影响。HRQoL 的特质成分与处于恋爱关系、就业和外向有关，与神经质呈负相关，这些因素总共解释了特质方差的 26%。
PLWH 的 HRQoL 与其人格和社会医学数据相当不同，这表明其在临床实践中的独特性。因此，对于这一患者群体，需要更全面地评估 HRQoL，以捕捉这一重要理论构建中额外的方差来源。
