Toddlers are vulnerable to unintentional injuries. A safety intervention targeting low-income families of toddlers, was effective at improving home safety. The current study examined whether the effect varies by initial home safety problems.
277 mother-toddler dyads recruited in the Mid-Atlantic region of the United States during 2007-2010 were randomized into safety promotion (n = 91) or attention-control groups (n = 186). Observers rated participants' homes with a 9-item safety problem checklist at baseline, and at 6- and 12-months follow-up. Initial home safety problems were categorized as multiple (≥ 4 problems) and none/few (< 4). Linear mixed models assessed the moderating effect with a three-way interaction (time, intervention, and initial safety problems).
At 12 months, the intervention effect was stronger among families with multiple initial problems than no/few initial problems, with a reduction of 1.55 more problems among the families with multiple problems, compared to the families with no/few problems (b = - 1.55, SE = 0.62, p = 0.013).
Interventions targeting families with multiple safety problems may be more effective than universal programming.
幼儿容易受到意外伤害。一项针对低收入家庭幼儿的安全干预措施在提高家庭安全性方面非常有效。本研究旨在探讨这种效果是否因初始家庭安全问题而异。
2007 年至 2010 年期间，在美国中大西洋地区招募了 277 对母婴二人组，随机分为安全促进组（n=91）和对照组（n=186）。观察者在基线、6 个月和 12 个月随访时使用 9 项安全问题检查表对参与者的家庭进行评估。初始家庭安全问题分为多种（≥4 个问题）和无/少（<4 个）。线性混合模型使用三因素交互作用（时间、干预和初始安全问题）评估了调节效应。
在 12 个月时，与初始问题较少的家庭相比，初始问题较多的家庭的干预效果更强，在存在多种初始问题的家庭中，问题减少了 1.55 个，而在初始问题较少的家庭中，问题减少了 0.62 个（b=-1.55，SE=0.62，p=0.013）。
针对存在多种安全问题的家庭的干预措施可能比通用方案更有效。
