To provide a preliminary test of a theory of planned behavior (TPB) belief-based intervention to increase adolescents' sun-protective behaviors in a high risk area, Queensland, Australia.
In the period of October-November, 2007 and May-June, 2008, 80 adolescents (14.53 ± 0.69 years) were recruited from two secondary schools (one government and one private) in Queensland after obtaining student, parental, and school informed consent. Adolescents were allocated to either a control or intervention condition based on the class they attended. The intervention comprised three, one hour in-school sessions facilitated by Cancer Council Queensland employees with sessions covering the belief basis of the TPB (i.e., behavioral, normative, and control [barrier and motivator] sun-safe beliefs). Participants completed questionnaires assessing sun-safety beliefs, intentions, and behavior pre- and post-intervention. Repeated Measures Multivariate Analysis of Variance was used to test the effect of the intervention across time on these constructs.
Students completing the intervention reported stronger sun-safe normative and motivator beliefs and intentions and the performance of more sun-safe behaviors across time than those in the control condition.
Strengthening beliefs about the approval of others and motivators for sun protection may encourage sun-safe cognitions and actions among adolescents.
初步检验基于计划行为理论（TPB）信念的干预措施，以提高澳大利亚昆士兰州高风险地区青少年的防晒行为。
在 2007 年 10 月至 11 月和 2008 年 5 月至 6 月期间，在获得学生、家长和学校同意后，从昆士兰州的两所中学（一所公立和一所私立）招募了 80 名青少年（14.53±0.69 岁）。根据他们所在的班级，将青少年分配到对照组或干预组。干预措施包括由昆士兰癌症委员会员工进行的三次、每次一小时的校内课程，课程涵盖 TPB 的信念基础（即行为、规范和控制[障碍和激励]防晒信念）。参与者在干预前后完成了评估防晒信念、意图和行为的问卷。采用重复测量多元方差分析来检验干预措施在时间上对这些结构的影响。
完成干预的学生报告称，他们具有更强的防晒规范和激励信念以及意图，并且在整个时间内表现出更多的防晒行为，而对照组的学生则没有。
增强对他人认可和防晒激励因素的信念可能会鼓励青少年采取防晒的认知和行动。
