Abstract

BACKGROUND

Improving adherence to self-protective behaviours is a public health priority. We aimed to assess the potential effectiveness and ease of use of an online version of the Risk Acceptance Ladder (RAL) in promoting help-seeking for cigarette smoking, excessive alcohol consumption, insufficient physical activity, or low fruit and vegetable consumption.

METHODS

843 UK adults were recruited, of whom 602 engaged in at least one risky behaviour. Those with no immediate plans to change (n = 171) completed a behaviour specific RAL. Participants were randomised to one of two conditions; a short message congruent (on-target, n = 73) or incongruent (off-target, n = 98) with their RAL response. Performance of the RAL was assessed by participants' ability to select an applicable RAL item and reported ease of use of the RAL. Effectiveness was assessed by whether or not participants clicked a link to receive information about changing their target behaviour.

RESULTS

Two thirds (68.9%, 95% CI = 61.8%-75.3%) of participants were able to select an applicable RAL item that corresponded to what they believed would need to change in order to alter their target behaviour, with 64.9% (95% CI = 57.5%-71.7%) reporting that it was easy to select one option. Compared with the off-target group, participants allocated to the on-target group had greater odds of clicking on the link to receive information (31.5% vs 19.4%; OR = 2.07, 95% CI = 1.01-4.26).

CONCLUSION

The Risk Acceptance Ladder may have utility as a tool for tailoring messages to prompt initial steps to engaging in self-protective behaviours.

摘要

背景

提高对自我保护行为的依从性是公共卫生的重点。我们旨在评估在线版风险接受梯（RAL）在促进对吸烟、过度饮酒、缺乏身体活动或低水果和蔬菜摄入等行为的求助方面的潜在效果和易用性。

方法

招募了 843 名英国成年人，其中 602 人从事至少一种危险行为。那些没有立即改变计划的人（n = 171）完成了特定行为的 RAL。参与者被随机分配到两种条件之一；与他们的 RAL 反应一致（目标一致，n = 73）或不一致（目标不一致，n = 98）的短消息。通过参与者选择适用的 RAL 项的能力以及报告 RAL 的易用性来评估 RAL 的性能。有效性通过参与者是否点击链接以获取有关改变目标行为的信息来评估。

结果

三分之二（68.9%，95%CI=61.8%-75.3%）的参与者能够选择与他们认为需要改变以改变目标行为相对应的适用 RAL 项，其中 64.9%（95%CI=57.5%-71.7%）报告说选择一个选项很容易。与目标不一致组相比，分配到目标一致组的参与者点击链接以获取信息的可能性更大（31.5%比 19.4%；OR=2.07，95%CI=1.01-4.26）。
