Incentive Amounts-Prolific

Studies demonstrate that financial incentive programmes increase smoking cessation. However, there is little guidance on which incentive magnitudes will ensure optimal enrolment and motivation levels. This study investigates current smokers’ perceptions of varying incentive magnitudes to identify whether there is evidence for optimal amount(s), and whether perceptions differ by income group. Studies 1 (N = 56) and 2 (N = 147) were conducted online via Prolific.co. Current smokers were randomly shown multiple hypothetical incentive programmes which differed only in the incentive amount offered. For each programme, smokers rated its appeal, their likelihood of enrolling, and predicted their motivation to quit if enrolled.多项研究表明，经济激励计划可有效提升戒烟成功率。然而，目前尚无明确指南可说明何种规模的激励金额能够确保最优的招募人数与参与动机水平。本研究旨在调查当前吸烟者对不同金额激励方案的认知，以探明是否存在最优激励金额的相关证据，同时分析吸烟者的认知是否因收入群体不同而存在差异。 本研究包含两项实验：实验1（样本量N=56）与实验2（样本量N=147）均通过Prolific.co在线平台开展。研究人员向当前吸烟者随机展示多款仅激励金额存在差异的假设性戒烟激励计划，针对每款计划，吸烟者需对其吸引力、自身参与该计划的可能性以及若参与后预计的戒烟动机进行评分。
