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.
