Adolescence has received particular attention given its unique risk factors, which contribute to the onset and progression of problem behaviour and its development with varying levels of seriousness. Although much adolescent problem behaviour is exploratory, a screening tool is required to identify early problem behaviour, to enable the use of preventive strategies to prevent more serious or persistent behaviour. The problem behaviour frequency scale developed by Farrell et al. (2000) was adapted and validated for this purpose. Method: A sample of Spanish adolescents was obtained comprising 508 subjects, made up of two groups: 318 in the study group (62.7%) and 189 in the comparison group (37.3%). The sample was made up of 62.9% males and 37.1% females, aged between 12 and 18. Various structural models were evaluated and the evidence for reliability, structural validity, sensitivity and specificity was calculated. A cut-off point was established for diagnosis, and differences between case and control groups were identified. Result: The bifactor model obtained the best fit, affirming the hypothesis on unidimensionality of PBFS and supporting the concept of problem behaviour syndrome. Discussion: Results suggest that PBFS is a reliable and valid instrument for identifying problem behaviour

鉴于其独特的风险因素，青春期受到了特别的关注，这些因素导致问题行为的发生和发展及其严重程度不同的发展。尽管许多青少年问题行为是探索性的，但需要一种筛查工具来识别早期问题行为，以便能够使用预防策略来防止更严重或持续存在的行为。Farrell 等人开发的问题行为频率量表。（2000）为此目的进行了改编和验证。方法：获得西班牙青少年样本，包括 508 名受试者，分为两组：研究组 318 人（62.7%）和对照组 189 人（37.3%）。样本由 62.9% 的男性和 37.1% 的女性组成，年龄在 12 至 18 岁之间。评估了各种结构模型，并计算了可靠性、结构有效性、敏感性和特异性的证据。为诊断建立了一个截止点，并确定了病例组和对照组之间的差异。结果：双因子模型获得最佳拟合，证实了PBFS的一维假设，支持了问题行为综合征的概念。讨论：结果表明，PBFS 是识别问题行为的可靠且有效的工具 肯定 PBFS 的一维性假设，支持问题行为综合征的概念。讨论：结果表明，PBFS 是识别问题行为的可靠且有效的工具 肯定 PBFS 的一维性假设，支持问题行为综合征的概念。讨论：结果表明，PBFS 是识别问题行为的可靠且有效的工具
