Informal caregivers experience daily hassles - a form of persistent stress, as a consequence of caregiving. This study aimed to develop and test a new theoretical model of health information-seeking behaviour, the Knowledge Hassles Information Seeking Model (KHISM). KHISM hypothesized that the knowledge hassles of caregivers - daily stressors experienced while dealing with tasks which require knowledge about the safety and effectiveness of the care-recipients' medicines - would influence caregivers' willingness to assist their care-recipient to use an Australian medication management service, Home Medicines Review (HMR).
A cross-sectional postal survey was conducted among 2350 members of Carers (NSW, Australia). Respondents were included in the study if they were involved in medication-related tasks for their care-recipient and were not paid as caregivers. Also, their care-recipient needed to be taking more than five medicines daily or more than 12 doses daily and had not yet experienced HMR. Structural equation modelling was used to test the model.
A total of 324 useable surveys were returned yielding a response rate of 14%. Respondents were quite willing to assist their care-recipient to use HMR (willingness). The model predicted 51% of the variation in willingness. Knowledge hassles increased positive outcome expectancy (β = 0.40, P < 0.05) and indirectly increased willingness.
The more caregivers experience hassles with medication knowledge, the more they perceive HMR to be a helpful information source and the more willing they are to use it. Targeted marketing centred on HMR as an information source may increase caregivers' demand for HMR. Further exploration of the phenomenon of knowledge hassles is warranted.
非正式照料者会经历日常困扰——一种持续压力的形式，这是照料行为的结果。本研究旨在开发并测试一种新的健康信息寻求行为理论模型，即知识困扰信息寻求模型（KHISM）。KHISM假设，照料者的知识困扰——在处理需要了解受照料者药物安全性和有效性知识的任务时所经历的日常压力源——会影响照料者协助其受照料者使用澳大利亚药物管理服务“家庭药物审查”（HMR）的意愿。
对澳大利亚新南威尔士州照料者协会的2350名成员进行了横断面邮寄调查。如果受访者参与了为其受照料者进行的与药物相关的任务且未领取照料报酬，则纳入本研究。此外，其受照料者每天需服用五种以上药物或每天服药超过12剂，且尚未接受过HMR服务。采用结构方程模型对该模型进行测试。
共收回324份可用调查问卷，回复率为14%。受访者非常愿意协助其受照料者使用HMR（意愿度）。该模型预测了意愿度变化的51%。知识困扰增加了积极结果预期（β = 0.40，P < 0.05），并间接增加了意愿度。
照料者在药物知识方面遇到的困扰越多，就越认为HMR是一个有用的信息来源，也就越愿意使用它。以HMR作为信息来源进行有针对性的营销可能会增加照料者对HMR的需求。有必要进一步探索知识困扰这一现象。
