Affect lability, an important aspect of emotion dysregulation, characterizes several psychiatric conditions. The short Affective Lability Scales (ALS-18) measures three aspects of changeability between euthymia and affect states (Anxiety/Depression, AD; Depression/Elation, DE; and Anger, Ang). The aim of our study was to investigate the psychometric characteristics of an Italian version of the ALS-18 in a sample of adults recruited from the general population. The sample was composed of 494 adults (343 women and 151 men) aged 18 and higher (mean age = 31.73 years, = 12.6). All participants were administered a checklist assessing socio-demographic variables, the ALS-18 and measures of depression and difficulties in emotion regulation. Confirmatory factor analyses indicated adequate fit of the three-factor model (RMSEA = 0.061, 95% CI = 0.054/0.069; CFI = 0.99; SRMR = 0.055), and the presence of a higher-order general factor. Internal consistency was satisfactory for all the lower-order dimensions and the general factor (ordinal α > 0.70). The ALS-18 was significantly associated with concurrent measures of depression and difficulties in emotion regulation. These findings indicate that the ALS-18 is a valid and reliable instrument for measuring affect lability, although discriminant validity of subdimensions scores could be problematic.
情感易激惹是情绪调节障碍的一个重要方面，是几种精神疾病的特征。简短情感易激惹量表（ALS - 18）测量了心境正常与情感状态之间的三个可变性方面（焦虑/抑郁，AD；抑郁/欣快，DE；愤怒，Ang）。我们研究的目的是在从普通人群中招募的成年人样本中，调查意大利语版ALS - 18的心理测量特征。样本由494名18岁及以上的成年人组成（343名女性和151名男性）（平均年龄 = 31.73岁，标准差 = 12.6）。所有参与者都接受了一份评估社会人口统计学变量的清单、ALS - 18以及抑郁和情绪调节困难的测量。验证性因素分析表明三因素模型拟合良好（RMSEA = 0.061，95% CI = 0.054/0.069；CFI = 0.99；SRMR = 0.055），并且存在一个高阶一般因素。所有低阶维度和一般因素的内部一致性都令人满意（顺序α > 0.70）。ALS - 18与抑郁和情绪调节困难的同时测量显著相关。这些发现表明，ALS - 18是测量情感易激惹的有效且可靠的工具，尽管子维度分数的区分效度可能存在问题。
