To synthesise theory of planned behaviour (TPB) relationships, using meta-analysis, and test the predictive utility of the model for sun protection behaviour.
Thirty-eight samples were identified via database/manual searches and academic society posts based on the criteria: measuring sun-protective intentions and/or prospective behaviour; using the TPB/theory of reasoned action as a basis of measurement; and providing bivariate correlations for at least one relevant TPB association.
Sun-protective intentions and behaviours.
The sample-weighted average effects were moderate-to-strong with attitudes showing the strongest association with intention (r+ = 0.494), followed by perceived behavioural control (PBC; r+ = 0.451), and subjective norm (r+ = 0.419). Intentions showed a stronger association with prospective behaviour (r+ = 0.486) compared to PBC (r+ = 0.314). A total of 39% of variance in intentions and 25% of variance in behaviour were explained. Publication bias was not evident. Moderator analyses showed that TPB associations were stronger when measures specified the Target, Action, Context and Time; in non-student samples; and when follow-up exceeded two weeks.
Despite recent criticism, this review shows that the TPB explains a large amount of variance in sun protection and that TPB associations are robust across different populations.
运用元分析综合计划行为理论（TPB）关系，并检验该模型对防晒行为的预测效用。
通过数据库/手动检索以及学术协会发布的内容，根据以下标准确定了38个样本：测量防晒意图和/或预期行为；以TPB/理性行动理论作为测量基础；并提供至少一种相关TPB关联的双变量相关性。
防晒意图和行为。
样本加权平均效应为中度至强度，态度与意图的关联最强（r+ = 0.494），其次是感知行为控制（PBC；r+ = 0.451）和主观规范（r+ = 0.419）。与PBC（r+ = 0.314）相比，意图与预期行为的关联更强（r+ = 0.486）。意图的39%的方差和行为的25%的方差得到了解释。发表偏倚不明显。调节分析表明，当测量明确了目标、行动、背景和时间时；在非学生样本中；以及随访超过两周时，TPB关联更强。
尽管最近受到批评，但本综述表明TPB解释了防晒方面的大量方差，并且TPB关联在不同人群中具有稳健性。
