There is some evidence that housing accessibility, external housing-related control beliefs (HCB) and activities of daily living (ADL) are associated in complex ways; however, these pathways have not been explored in younger old. The aim was to assess the role of external HCB in the relationship between housing accessibility and ADL by applying moderation and mediation models. This was a cross-sectional study involving 366 community-living 67–70 years old participants from the Skåne part of the Swedish National Study of Aging and Care. We assessed moderation by including an interaction term in a logistic regression analysis (significant if p value < 0.05). We assessed mediation with a series of regression analyses with effect size measures expressed as proportion mediated and its 95% confidence interval (CI). In the absence of statistically significant interaction there was no support for external HCB as a moderator. There was evidence for partial mediation as external HCB was associated with ADL when controlled for housing accessibility, while housing accessibility remained associated with independence in ADL when adjusted for external HCB. The proportion mediated was 6% (95% CI 1; 14). While the results did not support external HCB as a moderator, external HCB mediated the association between housing accessibility and ADL. These results were different from previous findings suggesting that external HCB plays a marginally significant moderating and mediating role among very old. Such differences call for further studies that would allow further exploration and validation of the findings at different stages of the ageing process, preferably utilizing longitudinal study designs.

住房可及性，与住房有关的控制信念与日常生活活动的独立性之间的关联：瑞典年轻人中的横断面研究

有证据表明，住房可及性，与住房相关的外部控制信念（HCB）和日常生活活动（ADL）之间的联系复杂。但是，这些途径尚未在更年轻的年龄中探索。目的是通过应用仲裁和调解模型来评估外部六氯代苯​​在住房可及性与ADL之间的关系中的作用。这是一项横断面研究，涉及来自瑞典国家老龄和护理研究国家斯科讷地区的366位67-70岁社区生活参与者。我们通过在逻辑回归分析中包括一个交互项来评估审核的适度性（如果p值<0.05）。我们通过一系列回归分析对调解进行了评估，效果大小的度量表示为介导的比例及其95％置信区间（CI）。在没有统计学上显着的相互作用的情况下，不支持外部六氯代苯​​作为主持人。有证据表明部分调解是因为在控制住房可及性时，外部六氯苯与ADL有关，而对外部HCB进行调整后，住房可及性仍与ADL中的独立性有关。介导的比例为6％（95％CI 1; 14）。尽管结果不支持外部HCB作为主持人，但外部HCB调节了房屋可及性与ADL之间的联系。这些结果与以前的发现不同，这表明外部HCB在非常老的人群中起着重要的调节和调节作用。
