BACKGROUND/PURPOSE: Every year, unintentional injury claims thousands of children's lives and causes disabilities in many more. For very young children, these injuries often occur at home. The risks of domestic injury can be reduced through proper implementation of injury preventive measures. In this study, we investigated the motivational and belief processes underlying childhood domestic injury prevention in grandparent caregivers based on the integrated model of self-determination theory and theory of planned behaviour.
Grandparents (n=299, mean age=62.61 years, SD=5.91, men=20.07%) of 0-2-year-old infants and toddlers self-reported their perceived psychological need support, autonomous motivation, perceived behavioural control (PBC), subjective norms, attitude, intention and adherence with regard to domestic injury prevention for their children at two time points (T1: baseline, T2: 4-month follow-up).
RESULTS/OUTCOMES: Data were analysed with structural equation modelling, and the proposed model yielded an acceptable fit with the data: χ=905.09 (df=531), Comparative Fit Index=0.94, Tucker-Lewis Index=0.93, root mean square error of approximation=0.05 and standardised root mean square residual=0.078. Our results supported our hypothesis, demonstrating significant and positive associations between the following key constructs: (1) psychological need support from family and autonomous motivation; (2) autonomous motivation and social-cognitive beliefs; (3) social-cognitive beliefs and intentions; and (4) intention and behavioural adherence. Subjective norms and PBC, but not attitudes, were also found to significantly mediate the indirect effects of psychological need support and autonomous motivation on intention and behavioural adherence.
Overall, the integrated model seems to be a feasible framework for explaining grandparents' domestic injury prevention behaviour.
背景/目的：每年，意外伤害夺走成千上万儿童的生命，并导致更多儿童残疾。对于幼儿来说，这些伤害通常发生在家中。通过正确实施伤害预防措施，可以降低家庭伤害的风险。在本研究中，我们基于自我决定理论和计划行为理论的综合模型，调查了祖父母照顾者预防儿童家庭伤害背后的动机和信念过程。
0至2岁婴幼儿的祖父母（n = 299，平均年龄 = 62.61岁，标准差 = 5.91，男性占20.07%）在两个时间点（T1：基线，T2：4个月随访）自我报告他们对为孩子预防家庭伤害的感知心理需求支持、自主动机、感知行为控制（PBC）、主观规范、态度、意图和依从性。
结果/成果：采用结构方程模型对数据进行分析，所提出的模型与数据拟合良好：χ = 905.09（自由度 = 531），比较拟合指数 = 0.94，塔克 - 刘易斯指数 = 0.93，近似误差均方根 = 0.05，标准化残差均方根 = 0.078。我们的结果支持了我们的假设，表明以下关键构念之间存在显著的正相关：（1）来自家庭的心理需求支持与自主动机；（2）自主动机与社会认知信念；（3）社会认知信念与意图；（4）意图与行为依从性。还发现主观规范和PBC，而非态度，显著中介了心理需求支持和自主动机对意图和行为依从性的间接影响。
总体而言，综合模型似乎是解释祖父母家庭伤害预防行为的一个可行框架。
