Abstract：
UNASSIGNED: Although previous research has examined the risk factors for drowning behavior among adolescents, it is unclear whether this association is influenced by water safety knowledge. This study aimed to examine whether water safety knowledge is associated with adolescents\' drowning risk behaviors and whether drowning risk perceptions and attitudes could have a chain mediating role in the association between water safety knowledge and adolescents\' drowning risk behaviors.
UNASSIGNED: This study included 7,485 adolescents from five Chinese provinces and cities. We used the Drowning Risk Behaviors Scales (DRBS) to evaluate the risk of drowning behaviors. The Water Safety Knowledge Scale (WSKS) was used to evaluate the competence level of water safety knowledge. The Drowning Risk Perceptions Scale (DRPS) was used to evaluate the risk level of perceptions, and the Drowning Risk Attitudes Scale (DRAS) was used to evaluate the risk level of attitudes.
UNASSIGNED: The results of the mediating effect test showed that water safety knowledge (WSK) affected drowning risk behaviors (DRB) through three indirect paths. Drowning risk perceptions (DRP) and attitudes (DRA) have significantly mediated the association between WSK and DRB. In conclusion, DRP and DRA can act as mediators between WSK and DRB, not only individually, but also as chain mediators, where the direct effect is-0.301, the total indirect effect is-0.214, and the total mediated indirect effect is 41.5%.
UNASSIGNED: Water safety knowledge negatively predicts adolescents\' drowning risk behaviors; water safety knowledge has an inhibitory effect on drowning risk perceptions. Water safety knowledge can directly influence adolescents\' drowning risk perceptions and indirectly affect drowning risk behaviors through the mediation of drowning risk perceptions and attitudes comprising three paths: (1) the drowning risk perceptions mediation path, (2) the drowning risk attitudes mediation path, and (3) the drowning risk perceptions and attitudes mediation paths.

摘要：
■尽管以前的研究已经调查了青少年溺水行为的危险因素，目前尚不清楚这种关联是否受到水安全知识的影响。这项研究旨在研究水安全知识是否与青少年溺水风险行为相关，以及溺水风险认知和态度是否在水安全知识与青少年溺水风险行为之间的关联中具有连锁中介作用。
■这项研究包括来自中国五个省市的7485名青少年。我们使用溺水风险行为量表（DRBS）来评估溺水行为的风险。采用水安全知识量表(WSKS)评价水安全知识能力水平。溺水风险感知量表(DRPS)用于评估感知的风险水平，溺水风险态度量表(DRAS)用于评估态度的风险水平。
■中介效应测试的结果表明，水安全知识（WSK）通过三种间接路径影响溺水风险行为（DRB）。溺水风险感知(DRP)和态度(DRA)显著介导了WSK和DRB之间的关联。总之,DRP和DRA可以充当WSK和DRB之间的调解人，不仅是个人,而且作为链条中介，其中直接效应为-0.301，总间接效应为-0.214，总介导间接效应为41.5%。
■水安全知识对青少年的溺水危险行为有负面影响；水安全知识对溺水危险感知有抑制作用。水安全知识可以通过溺水风险感知和态度的中介作用直接影响青少年溺水风险感知，间接影响溺水风险行为，包括三个路径：（1）溺水风险感知中介路径，(2)溺水风险态度调解路径,(3)溺水风险感知和态度调解路径。
