To evaluate the psychometric properties of the Italian translation of the Schedule for Nonadaptive and Adaptive Personality-2 (SNAP-2) diagnostic scales, 837 Italian community-dwelling adults and 429 consecutively admitted Italian psychiatric adults were administered the SNAP-2. The 12 SNAP-2 diagnostic scales yielded reliable scores in both community (median ω value = .90) and psychiatric (median ω value = .92) samples. The 6-month temporal stability was adequate for all SNAP-2 diagnostic scales (median test-retest r-value = .84) in a subsample of the community-dwelling adults (n = 97). When we examined the correlations between the SNAP-2 diagnostic scales and the Five-Factor Model Rating Form trait scales among the community-dwelling adults, the double-entry intraclass correlation values (median ICCDE = .94) indicated a marked similarity between our correlation profiles and the correlation profiles that were reported in Samuel and Widiger (2008) meta-analysis. In our psychiatric-adult sample, the SNAP-2 diagnostic scales showed adequate convergent-validity coefficients (median r-value = .61) with criterion measures of DSM-IV axis II/DSM-5 Section II personality disorders (PDs). Finally, relative-weight analysis results showed that selected Personality Inventory for DSM-5 trait-scale scores explained a substantial amount of variance in SNAP-2 antisocial, avoidant, borderline, narcissistic, obsessive-compulsive, and schizotypal PD scale scores (median R 2 value = .55). As a whole, our data suggest that the Italian SNAP-2 diagnostic scales have adequate reliability and construct validity in the Italian culture.

意大利社区居民和精神病患者中非适应性和适应性人格表 2 (SNAP-2) 诊断量表的可靠性和有效性。

为了评估非适应性和适应性人格表 2 (SNAP-2) 诊断量表的意大利语翻译的心理测量特性，对 837 名意大利社区居民和 429 名连续入院的意大利精神病成年人进行了 SNAP-2。12 个 SNAP-2 诊断量表在社区（中值 ω 值 = .90）和精神病（中值 ω 值 = .92）样本中均产生了可靠的分数。6 个月的时间稳定性足以满足社区居民子样本 (n = 97) 中所有 SNAP-2 诊断量表（中值测试-再测试 r 值 = .84）的需求。当我们检查社区居民中 SNAP-2 诊断量表和五因素模型评定表特征量表之间的相关性时，复式类内相关值（中值 ICCDE = . 94) 表明我们的相关性特征与 Samuel 和 Widiger (2008) 荟萃分析中报告的相关性特征之间存在显着的相似性。在我们的精神病学-成人样本中，SNAP-2 诊断量表显示出足够的收敛效度系数（中值 r 值 = .61）以及 DSM-IV 轴 II/DSM-5 第二节人格障碍 (PD) 的标准度量。最后，相对权重分析结果表明，所选的 DSM-5 特质量表分数的人格量表解释了 SNAP-2 反社会、回避、边缘、自恋、强迫症和分裂型 PD 量表分数（中位数 R 2 值 = .55）。总的来说，我们的数据表明意大利 SNAP-2 诊断量表在意大利文化中具有足够的可靠性和结构效度。（PsycInfo 数据库记录 (c) 2021 APA，
