Validated instruments that measure intimate partner violence (IPV) following separation from an abusive co-parent ("post-separation abuse" (PSA)), are needed to understand and mitigate risks to child health. Items for the Healthcare, Economic, and Legal Post-Separation Abuse and Coercive Tactics (HELP-T) Scale were generated based on qualitative interviews with maternal survivors ( = 33) and expert review. Reliability, construct validity, and concurrent validity were tested in a sample ( = 497) of maternal survivors experiencing PSA in the US. Exploratory factor analysis assessed construct validity, and Cronbach's alpha assessed subscale reliability. Iterative principal factor analysis revealed 3 subscales for 22 items that were labeled (1) Healthcare PSA, (2) Legal PSA, and (3) Economic PSA, and demonstrated strong reliability with Cronbach's alphas from 0.82 to 0.89. The three subscales exhibit strong preliminary psychometric properties and provide insights to help health and legal professionals measure and establish PSA tactics.
为了了解并降低对儿童健康的风险，需要有经过验证的工具来测量与有虐待行为的共同父母分居后发生的亲密伴侣暴力（IPV，即“分居后虐待”（PSA））。医疗、经济和法律方面的分居后虐待及强制手段（HELP-T）量表的条目是根据对母亲幸存者（n = 33）的定性访谈和专家评审生成的。在美国，对497名经历分居后虐待的母亲幸存者样本进行了信度、结构效度和同时效度测试。探索性因素分析评估结构效度，克朗巴哈系数评估子量表信度。迭代主成分分析揭示了22个条目的3个子量表，分别标记为（1）医疗保健方面的分居后虐待，（2）法律方面的分居后虐待，以及（3）经济方面的分居后虐待，并显示出很强的信度，克朗巴哈系数在0.82至0.89之间。这三个子量表表现出很强的初步心理测量特性，并为帮助健康和法律专业人员测量和确定分居后虐待策略提供了见解。
