The 26-item version of the Metacognitive Anger Processing Scale (MAP) has shown good psychometric properties in previous studies. However, there is a need for a shorter version of the scale.
The aim of the present study is to psychometrically evaluate the 9-item Metacognitive Anger Processing Scale - Short Version (MAP-SV) in comparison with the original, 26-item version.
The 26-item MAP includes three subscales: rumination, positive beliefs and negative beliefs. Three items from each subscale were selected based on clinical validity to constitute the 9-item MAP-SV. A previous sample used for validation of the 26-item MAP was used for clinimetric testing. The sample included psychiatric patients (n = 88) and male forensic inpatients (n = 54). The MAP-SV was assessed according to scalability, convergent validity with general metacognition, and concurrent validity with anger measures.
The scalability of the 9-item MAP-SV was comparable to that of the original 26-item MAP in most psychometric tests. The Loevinger's coefficient of homogeneity for the total score of the MAP-SV items was 0.29 for the combined sample compared with 0.36 in the original MAP, indicating close to acceptable scalability. The alpha coefficient for the MAP-SV total score was 0.79. For the combined sample, Pearson inter-correlations between the subscales of the MAP-SV were highly correlated with the MAP-SV total score (ranging from .66 to .84).
The 9-item MAP-SV showed good psychometric properties and can be used as a reliable tool for assessing self-reported metacognitive anger processing.
26 项版本的元认知愤怒处理量表（MAP）在先前的研究中表现出了良好的心理测量特性。然而，我们需要一个更简短的版本。
本研究旨在心理测量评估 9 项元认知愤怒处理量表-短版（MAP-SV）与原始的 26 项版本的区别。
26 项 MAP 包括三个分量表：反刍、积极信念和消极信念。根据临床有效性从每个分量表中选择三个项目，构成 9 项 MAP-SV。一个用于验证 26 项 MAP 的先前样本被用于临床测试。该样本包括精神科患者（n=88）和男性法医住院患者（n=54）。根据可扩展性、与一般元认知的收敛效度以及与愤怒测量的同时效度来评估 MAP-SV。
在大多数心理测量测试中，9 项 MAP-SV 的可扩展性与原始的 26 项 MAP 相当。MAP-SV 项目总分的 Loevinger 同质性系数在合并样本中为 0.29，而原始 MAP 中为 0.36，表明接近可接受的可扩展性。MAP-SV 总分的 alpha 系数为 0.79。对于合并样本，MAP-SV 各分量表之间的 Pearson 相关系数与 MAP-SV 总分高度相关（范围从 0.66 到 0.84）。
9 项 MAP-SV 表现出良好的心理测量特性，可以作为评估自我报告的元认知愤怒处理的可靠工具。
