The Child Abuse Potential Inventory (CAP) is a widely used instrument to assess the potential for child abuse. The brief version of the CAP (BCAP) is a proven time-efficient screener tool. This investigation aims to propose a Spanish BCAP version by analyzing the factor structure of its Abuse Scale (aim 1) and, if needed, developing a valid BCAP Lie Scale (aim 2). Study 1 comprised 205 mothers with problems coping with their children’s behavior recruited from family support and treatment programs. Confirmatory factor analysis (CFA), internal consistency, and convergent validity were conducted. Study 2 applied an experimental between-subject design to assess a convenience sample of the Spanish population (N = 260) with 124 participants in Condition 1 (honest) and 136 in Condition 2 (lie). Differences between conditions were analyzed. Study 1: CFA showed adequate fit indices for the seven-factor model (RMSEA = .04 CFI = .98, TLI = .98). Internal consistency and convergent validity were adequate for the Abuse Scale. Findings also showed that the BCAP Lie Scale does not accomplish the main requirements to detect participants answering in a socially desirable way. Study 2: A new set of six items showing significant differences between conditions (U = 15,481.00, z = 11.14, p < .001, r = .77) is proposed to compose the Lie Scale. The findings support that the Spanish BCAP is a valid instrument to assess mothers recruited from Child Protection Services. The new BCAP Lie Scale could be useful to select valid inventories. Further research with more representative samples is recommended.

潜在的虐待儿童清单（CAP）是评估虐待儿童潜力的一种广泛使用的工具。CAP的简短版本（BCAP）是一种行之有效的筛选工具。这项调查旨在通过分析其滥用量表（目标1）的因素结构，并在需要时制定有效的BCAP说谎量表（目标2）来提出西班牙语的BCAP版本。研究1包括205名母亲，他们从家庭支持和治疗计划中招募到了解决孩子行为问题的母亲。进行了验证性因素分析（CFA），内部一致性和收敛效度。研究2应用实验对象间设计评估了 条件为1的124名参与者的西班牙人口（N = 260）便利样本（诚实）和条件2中的136 （说谎）。分析条件之间的差异。研究1： CFA对七因素模型显示出足够的拟合指数（RMSEA  = .04 CFI  = .98，TLI  = .98）。内部一致性和收敛效度足以用于滥用量表。研究结果还表明，BCAP测谎量表不能满足检测参与者以社会期望的方式回答的主要要求。研究2：一组新的六个项目显示出条件之间的显着差异（U  = 15,481.00，z  = 11.14，p  <.001，r = 0.77）建议组成李氏量表。调查结果支持西班牙BCAP是评估从儿童保护服务局招募的母亲的有效工具。新的BCAP Lie量表可能有助于选择有效的库存。建议进一步研究具有代表性的样品。
