Impulsivity Scale-12 and its utilization in alcohol use disorder

Area of Science:

• Psychiatry
• Psychology
• Neuroscience

Background:

• Impulsivity is a core symptom of alcohol use disorder (AUD).
• The Impulsivity Scale 12 (IS-12) is a new, simple tool for assessing impulsivity.
• IS-12 has subscales for cognitive and behavioral impulsivity, relevant to AUD.

Purpose of the Study:

• To adapt the IS-12 for Polish-speaking AUD patients.
• To test the utility and psychometric properties of the Polish IS-12.
• To explore the relationship between IS-12 subscales and clinical symptoms in AUD.

Main Methods:

• Confirmatory Factor Analysis (CFA) compared Polish IS-12 and BIS-11 models in 615 AUD patients.
• Structural Equation Modeling (SEM) examined associations between IS-12 subscales and symptoms in 450 AUD patients.
• Reliability and model fit were assessed for both scales.

Main Results:

• The IS-12 showed better model fit and reliability than the BIS-11.
• Cognitive impulsivity predicted suicidal ideation; behavioral impulsivity predicted AUD severity.
• Both IS-12 subscales predicted depressive symptoms.

Conclusions:

• The IS-12 is a reliable and valid measure for AUD patients.
• The IS-12 demonstrates satisfactory model fit and predicts clinical symptomatology.
• IS-12 is a beneficial tool for clinicians and researchers working with AUD.
