The assessment of child and adolescent quality of life (QoL) is increasingly incorporated into practice and research within health and social care. However, little is known about the stability of the conceptualisation of QoL in the face of normative developmental processes against which to compare changes in response to non-normative events, such as chronic illness. The present study examined the stability of the QoL construct over 1 year in a cohort of healthy community-dwelling adolescents through applying the response shift (RS) model.
A cohort of 356 adolescents (M age = 14.05 years) completed the Kidscreen QoL measure on two occasions, 1 year apart. Both research-design and statistical techniques were employed to assess three types of RS: recalibration, reprioritisation and reconceptualisation.
A significant recalibration of small effect size was found for three QoL domains using a then-test, which was confirmed in the domain of autonomy through statistical modelling. No evidence was found for reprioritisation or reconceptualisation RS using either analytical approach.
The findings support the assumption that the conceptualisation of QoL is stable during adolescence in the absence of significant health threats. However, researchers and clinicians should be aware of potential recalibration effects of some life domains.
儿童和青少年生活质量(QoL)的评估越来越多地纳入健康和社会护理的实践与研究中。然而,面对正常发育过程,人们对生活质量概念化的稳定性知之甚少,而正常发育过程可用于比较因慢性疾病等非规范性事件而产生的变化。本研究通过应用反应转移(RS)模型,考察了健康社区青少年队列中生活质量结构在1年内的稳定性。
356名青少年(平均年龄 = 14.05岁)组成的队列在相隔1年的两个时间点完成了儿童生活质量量表的测评。采用研究设计和统计技术来评估三种类型的反应转移:重新校准、重新排序和重新概念化。
使用事后检验发现三个生活质量领域存在显著的小效应量重新校准,通过统计建模在自主性领域得到证实。两种分析方法均未发现重新排序或重新概念化反应转移的证据。
研究结果支持以下假设:在没有重大健康威胁的情况下,青少年时期生活质量的概念化是稳定的。然而,研究人员和临床医生应意识到某些生活领域可能存在的重新校准效应。
