Impaired illness awareness or inability to recognize that one has a substance use disorder can be a barrier to treatment seeking and rehabilitation. A validated scale is needed to better understand ...the clinical impact of impaired substance use disorder awareness. This study aimed to examine the psychometric properties of the Substance Use Awareness and Insight Scale (SAS), a novel scale to assess impaired illness awareness in individuals with substance use disorder.
We developed the SAS, a 7-item self-report measure to assess the theoretical constructs of illness awareness in substance use disorder (www.illnessawarenessscales.com). Participants 18 years of age or older with a score of 8 or more on the Drug Use Disorders Identification Test (DUDIT) were included. Data were collected via Dynata, an online survey platform.
A total of 299 participants were included (mean (SD) age = 47.3-years (15.4), 54% women). The SAS demonstrated good convergent (r = 0.82, p < 0.001) and discriminant validity (r = −0.23, p < 0.001) with a measure of illness recognition and positive affect, respectively. SAS also demonstrated good internal consistency (Cronbach’s alpha = 0.86) and one-month test-retest reliability (intra-class correlation = 0.87). An exploratory factor analysis suggested the retention of two components. Separate analyses of the SAS in individuals with cannabis, opioid, and other substance use showed similar results.
The results of this study provide initial support for the psychometric validation of the SAS in adults with substance use disorder. The SAS holds promise for use in research and clinical settings to assess the influence of impaired substance use disorder awareness on treatment outcomes.

Impaired illness awareness in individuals with alcohol use disorder can negatively affect treatment adherence, rehabilitation, and other clinical outcomes. However, the construct of illness awareness in alcohol use disorder and its clinical implications remain to be better conceptualized and understood. The objective of this study was to develop and psychometrically test a scale designed to assess impaired illness awareness in individuals with alcohol use disorder.
We developed the Alcohol Use Awareness and Insight Scale (AAS), a self-report measure that assesses the core theoretical domains of illness awareness, including general disorder or problem awareness, accurate symptom attribution, awareness of the need for treatment, and the negative consequences of the disorder in individuals with alcohol use disorder (www.illnessawarenessscales.com). Data from 99 participants was obtained using a web-based survey platform, Dynata.
The AAS displayed good convergent (r = 0.88, p < 0.001) and discriminant validity with measures of illness recognition and affect states, respectively. The AAS also exhibited good internal consistency (Cronbach’s α = 0.89) and one-month test-retest reliability (intra-class correlation = 0.84). Exploratory factor analysis resulted in the retention of a single component.
The AAS is a novel instrument developed to measure impaired illness awareness in individuals with alcohol use disorder. The AAS may be useful in clinical or research settings in evaluating the influence of subjective alcohol use disorder awareness on interventions to promote treatment adherence and other clinical outcomes.
Abstract
Introduction
Impaired illness awareness or the inability to recognize that one has a dependence on nicotine may be a major barrier to seeking cessation treatment. To better understand the ...role of impaired illness awareness on treatment-seeking behavior and clinical outcomes, we developed and examined the psychometric properties of a novel scale measuring illness awareness in individuals with dependence on nicotine.
Aims and Methods
We developed the Nicotine Use Awareness and Insight Scale (NAS), a 7-item self-report measure to assess the theoretical construct of illness awareness in individuals with dependence on nicotine (www.illnessawarenessscales.com). Data from participants 18 years of age or older were collected via a web-based survey company, Dynata. Participants with moderate dependence on nicotine were included, defined by a score of four or more on the Fagerström Test for Cigarette Dependence (FTCD) or the FTCD adapted for electronic cigarettes (eFTCD).
Results
A total of 100 participants (mean SD age = 49.1 16.1 years, 52% women) that met the inclusion criteria for either FTCD (n = 50) or eFTCD (n = 50) were included. The NAS demonstrated good convergent (r = .74, p < .001) and discriminant validity (r = .03, p = .786). It also demonstrated good internal consistency (Cronbach’s alpha = 0.78) and one-month test-retest reliability (intra-class correlation = 0.86). An exploratory factor analysis yielded the retention of two components.
Conclusions
The NAS is a novel scale to asses illness awareness in individuals with dependence on nicotine. This study provides initial support for the psychometric validity and reliability of NAS.
Implications
The NAS may be used in research and clinical practice to evaluate the impact of impaired illness awareness on treatment-seeking behavior and clinical outcomes.
