Adolescents put themselves at risk of later skin cancer development and accelerated photo-aging due to their high rates of ultraviolet radiation exposure and low rates of skin protection. The purpose of the current study was to determine which of the Integrative Model constructs are most closely associated with sunscreen use among high school students.
The current study of 242 high school students involved a survey based on the Integrative Model including demographic and individual difference factors, skin protection-related beliefs and outcome evaluations, normative beliefs, self-efficacy, sunscreen cues and availability, intentions, and sunscreen use. Our analyses included multiple linear regressions and bootstrapping to test for mediation effects.
Sunscreen use was significantly associated with female gender, greater skin sensitivity, higher perceived sunscreen benefits, higher skin protection importance, more favorable sunscreen user prototype, stronger skin protection norms, greater perceived skin protection behavioral control, and higher sunscreen self-efficacy. Intentions to use sunscreen mediated the relationships between most skin protection-related beliefs and sunscreen use.
The current study identified specific variables that can be targeted in interventions designed to increase sunscreen use among adolescents.
青少年由于紫外线辐射暴露率高、皮肤保护率低,使他们处于日后罹患皮肤癌和加速光老化的风险之中。本研究旨在确定综合模型结构中哪些与高中生使用防晒霜的相关性最大。
本研究对 242 名高中生进行了一项基于综合模型的调查,其中包括人口统计学和个体差异因素、与皮肤保护相关的信念和结果评估、规范信念、自我效能感、防晒霜线索和可用性、意图以及防晒霜的使用。我们的分析包括多元线性回归和自举检验以测试中介效应。
防晒霜的使用与女性性别、更高的皮肤敏感性、更高的防晒霜益处感知、更高的皮肤保护重要性、更有利的防晒霜使用者原型、更强的皮肤保护规范、更强的皮肤保护行为控制以及更高的防晒霜自我效能感显著相关。使用防晒霜的意图中介了大多数与皮肤保护相关的信念与防晒霜使用之间的关系。
本研究确定了可以在干预措施中针对的特定变量,以增加青少年使用防晒霜的意愿。
