Abstract
Introduction: The objectives of this study were to develop a multidimensional, clinician-rated scale that assess impaired insight into illness in patients with alcohol use disorder (AUD) and to examine its reliability, validity and internal structure. Moreover, we investigated the relationships of overall insight and its dimensions with demographic and clinical characteristics in AUD. Methods: We developed the Schedule for the Assessment of Insight in Alcohol Dependence (SAI-AD), based on scales that has already been used in psychosis and other mental disorders. Sixty-four patients with AUD were assessed with SAI-AD. Hierarchical cluster analysis and multidimensional scaling were used to identify insight components and assess their inter-relationships. Results: The SAI-AD demonstrated good convergent validity (r = −0.73, p < 0.001) and internal consistency (Cronbach's alpha = 0.72). Inter-rater and test-retest reliabilities were high (intra-class correlations 0.90 and 0.88, respectively). Three subscales of SAI-AD were identified which measure major insight components: awareness of illness, recognition of symptoms and need for treatment, and treatment engagement. Higher levels of depression, anxiety and AUD symptom severity were associated with overall insight impairment but not with recognition of symptoms and need for treatment, or with treatment engagement. Illness duration was specifically and positively associated with the treatment engagement component of insight. Conclusions: Insight is a multidimensional construct in AUD and its major components appear to be associated with different clinical aspects of the disorder. The SAI-AD is a valid and reliable tool for the assessment of insight in AUD patients.
