PURPOSE
To investigate the construct validity of the ICECAP-A capability wellbeing measure.
METHODS
A face-to-face interview-administered survey was conducted with 418 members of the UK general population, randomly sampled from the Postcode Address File. Pre-specified hypotheses were developed about the expected associations between individuals' ICECAP-A responses and their socio-economic circumstances, health and freedom. The hypotheses were investigated using statistical tests of association.
RESULTS
The ICECAP-A responses and scores reflected differences across different health and socioeconomic groups as anticipated, but did not distinguish individuals by the level of local deprivation. Mean ICECAP-A scores reflected individuals' perceived freedom slightly more closely than did measures of health and happiness.
CONCLUSION
This study suggests that the ICECAP-A measure can identify expected differences in capability wellbeing in a general population sample. Further work could establish whether self-reported capabilities exhibit desirable validity and acceptability in sub-groups of the population such as patients, social care recipients and informal carers.
目的
研究 ICECAP-A 能力福利衡量标准的结构效度。
方法
对英国普通人群的 418 名成员进行了面对面的访谈式调查，这些成员是从邮政编码档案中随机抽取的。针对个人的 ICECAP-A 反应与他们的社会经济环境、健康和自由之间预期的关联，制定了预先确定的假设。使用关联的统计检验来检验这些假设。
结果
如预期的那样，ICECAP-A 的反应和分数反映了不同健康和社会经济群体之间的差异，但并没有根据当地贫困程度来区分个体。平均 ICECAP-A 分数比健康和幸福测量更能反映个人的感知自由。
结论
本研究表明，ICECAP-A 衡量标准可以识别一般人群样本中能力福利的预期差异。进一步的工作可以确定自我报告的能力在患者、社会护理接受者和非正式照顾者等人群亚组中是否表现出理想的有效性和可接受性。
