Abstract

BACKGROUND

Pretesting is the key to understanding how the intended audience will react to the message. Resistant reactions affect message processing or can lead to undesirable boomerang effects. The objective of this study was to develop a rating scale for measuring active (reactance) and passive (disengagement) resistance to persuasive health messages.

METHODS

Six candidate items (3 items for disengagement and 3 items for reactance) were generated based on literature review. A web-based survey was conducted among Japanese adults aged 25-64 years to verify the reliability and validity of the 6-item resistance scale. Participants were asked to rate one of the advance care planning (ACP) promotion messages. All scale items were scored on a 1-to-5 point Likert scale and they were averaged to produce the resistance score.

RESULTS

Explanatory factor analysis revealed a two-factor solution that agreed with the disengagement and reactance domains, respectively. Correlation coefficients between each set of items ranged between 0.30-0.69. Cronbach alpha (0.86) indicated satisfactory internal consistency of the set of items. Confirmatory factor analysis showed a good fit of the two-factor model with CFI = 0.998, SRMR = 0.011, and RMSEA = 0.041. The resistance score showed a moderate positive correlation with negative emotional responses (displeasure γ = 0.55, anger γ = 0.53) and was significantly inversely related to the persuasiveness score (γ = -0.50). Multivariable logistic regression analysis showed that the odds ratio for ACP intention per 1-point increase in the resistance score was 0.47 (95% confidence interval 0.40-0.56) with adjustment for the persuasiveness score.

CONCLUSION

The 6-item resistance scale exhibited adequate reliability and validity for measuring audience resistance when applied to the ACP promotion messages in Japanese people. The scale will be useful for pretesting health messages to make them more acceptable to the intended audience.

摘要

背景

预测试是了解目标受众对信息反应的关键。抵触反应会影响信息处理，或者导致不良的回旋镖效应。本研究的目的是开发一种测量对有说服力的健康信息的主动（抵触）和被动（脱逸）抵抗的评分量表。

方法

根据文献回顾，生成了 6 个候选项目（脱逸 3 项，抵触 3 项）。对 25-64 岁的日本成年人进行了基于网络的调查，以验证 6 项抵抗量表的可靠性和有效性。参与者被要求对一个预先护理计划（ACP）推广信息进行评分。所有量表项目均按 1-5 分的李克特量表评分，并取平均值得出抵抗得分。

结果

解释性因素分析显示出与脱逸和抵触领域分别对应的双因素解决方案。每一组项目之间的相关系数在 0.30-0.69 之间。克朗巴赫阿尔法（0.86）表明项目集具有令人满意的内部一致性。验证性因素分析显示，双因素模型拟合良好，CFI = 0.998，SRMR = 0.011，RMSEA = 0.041。抵抗得分与负面情绪反应（不悦 γ = 0.55，愤怒 γ = 0.53）呈中度正相关，与说服力得分呈显著负相关（γ = -0.50）。多变量逻辑回归分析显示，在调整说服力得分后，抵抗得分每增加 1 分，ACP 意向的比值比为 0.47（95%置信区间 0.40-0.56）。
