Although the Child Abuse Potential (CAP) Inventory is generally considered to be a reliable screening tool for assessing child physical abuse risk, there is concern that it may lack internal consistency when completed by adolescents (Blinn-Pike and Mingus, J Adolesc 2000;23:107-11). This concern has been reflected in subsequent reviews summarizing the CAP's psychometric properties (Walker and Davies, J Fam Violence 2010;25:215-27), and calls for data on the reliability of the CAP Inventory as completed by adolescents have been issued (Blinn-Pike, J Adolesc Health 2002;30:148). The purpose of this study was to provide additional data examining the internal consistency of the CAP Inventory as completed by adolescents in a variety of contexts.
This study included five samples comprising 3,281 adolescent and adult respondents who completed the CAP Inventory. Two samples included at-risk mothers who were enrolled in home-visiting services and were participating in program evaluations. Three samples included college students the majority of whom were nonparents participating in the research to explore the risk of physical abuse among children.
The analyses showed high internal consistency estimates for the CAP Inventory abuse scale as completed by adolescent mothers (Kuder-Richardson reliability coefficient range = .90-.96). Moreover, regardless of the sampling technique, parental status, or demographic characteristics, our analyses revealed overall good to excellent internal consistency estimates for the CAP Inventory abuse scale as completed by adolescent respondents. Indeed, the internal consistency estimates obtained from adolescent respondents were similar to the estimates obtained for adult respondents in each of these same samples.
Our results provide strong support for a claim of good to excellent internal consistency of the CAP Inventory with adolescent samples.
尽管儿童虐待倾向（CAP）量表通常被认为是评估儿童身体虐待风险的可靠筛查工具，但人们担心当由青少年完成时，它可能缺乏内部一致性。这种担忧反映在随后的综述中，这些综述总结了 CAP 的心理测量特性（Walker 和 Davies，J Fam Violence 2010；25：215-27），并呼吁提供有关青少年完成 CAP 量表可靠性的数据（Blinn-Pike，J Adolesc Health 2002；30：148）。本研究的目的是提供更多数据，以检查在各种情况下由青少年完成的 CAP 量表的内部一致性。
本研究包括五个样本，共有 3281 名青少年和成年受访者完成了 CAP 量表。两个样本包括参加家访服务并参与方案评估的高危母亲。三个样本包括大学生，其中大多数是非父母，他们参与研究是为了探索儿童身体虐待的风险。
分析结果表明，青少年母亲完成的 CAP 量表虐待量表具有较高的内部一致性估计值（Kuder-Richardson 可靠性系数范围为.90-.96）。此外，无论采用何种抽样技术、父母身份或人口统计学特征，我们的分析都表明，青少年受访者完成的 CAP 量表虐待量表的整体内部一致性估计值良好到优秀。事实上，从青少年受访者获得的内部一致性估计值与在这些相同样本中的成年受访者获得的估计值相似。
我们的结果为 CAP 量表在青少年样本中的良好到优秀的内部一致性提供了有力的支持。
