Psychometric Properties and Factor Structure of the Short Form of the Affective Lability Scale in Adult Patients With ADHD.
Objective:Affective lability is an important dimension of adult ADHD, associated with marked impairments and worse outcomes. A valid and quick tool to measure affective lability may therefore be of interest.Method:In 187 adult ADHD patients, we explored psychometric properties of the Affective Lability Scale-Short Form (ALS-18 items). We analyzed the construct validity and the external validity of the scale. Patients were compared with 48 healthy adult controls.Results:The three-factor structure of the ALS-18 presented a good fit and a good internal consistency. The correlations between the ALS-18 and ADHD symptoms and other psychological dimensions were, respectively, low and moderate. ALS-18 scores were higher in patients than in healthy adults.Conclusion:ALS-18 showed good psychometric properties in ADHD adult patients, allowing us to recommend the implementation of ALS-18 in assessing affective lability for clinical and research purposes. Use of ALS-18 should improve the clinical assessment of affective lability in adult ADHD patients.
