To evaluate CADRI's configural and metric structures and explore its performance from the perspective of the respondents as perpetrators and victims. In the process, we present shorter versions for both roles.
The sample consisted of 561 adolescents aged 15 and 19, enrolled in public and private schools in Rio de Janeiro, Brazil. Initially, confirmatory factor analyzes (CFA) tested the originally proposed dimensional structure. Since this model was rejected, the second step analyzed the data via Exploratory Structural Equation Models (ESEM) to reassess the instrument's structure. Applying a decision algorithm on a new dimensional structure, we proceeded to reduce the number of items to establish separate sets for victimization and perpetration. These final models were then analyzed via CFA to assess their psychometric properties.
The final solutions contained 15 items comprising four and three factors for victimization and perpetration, respectively. Thirteen items were common to both models, but two were unique to their respective sets. Regardless of their small differences, the final solutions fitted adequately, held factorial item pertinence and unambiguity, contained reliable and non-redundant items, and sustained factor-based convergent and discriminant validities.
The four and three-factor models were within the dimensional bounds proposed in the original CADRI, the shorter scales still succeeding in partially capturing what was envisaged in the first version of the instrument. However, the shorter versions suggested here are still tentative, thus requiring further examination.
评估 CADRI 的组态和度量结构，并从加害者和受害者的角度探讨其性能。在此过程中，我们为这两个角色呈现了更简短的版本。
该样本包括来自巴西里约热内卢公立和私立学校的 561 名 15 岁和 19 岁的青少年。最初，验证性因子分析（CFA）测试了最初提出的维度结构。由于该模型被拒绝，第二步通过探索性结构方程模型（ESEM）分析数据，重新评估该工具的结构。在新的维度结构上应用决策算法，我们继续减少项目数量，为受害和加害建立单独的集合。然后通过 CFA 分析这些最终模型，以评估其心理测量特性。
最终解决方案包含 15 个项目，分别为受害和加害各包含四个和三个因素。这两个模型有 13 个项目是共有的，但各自的集合中有两个是独特的。无论它们的差异很小，最终的解决方案都适配得很好，具有因子项目相关性和明确性，包含可靠且不冗余的项目，并维持基于因素的收敛和区分效度。
四因素和三因素模型都在 CADRI 最初提出的维度范围内，较短的量表仍然成功地部分捕捉到了工具最初版本的预期。然而，这里提出的较短版本仍然是暂定的，因此需要进一步的检验。
