Background: Substance use disorders present with multiple drug-related problems that need to be evaluated with a view to planning and administering holistic interventions that could potentially improve addiction treatment outcomes. Many valid instruments are available for assessing the problems that occur in addiction but most of them require some training and they take a lot of time to administer. This study validates a shorter self-administered version of the Addiction severity Index (ASI) against the Clinician-administered ASI with a view to cutting the time needed to administer the instrument. Methods: The study recruited 142 patients in a residential treatment center. Correlation coefficient and t-test were used to assess for the convergence of the two version. Results: The correlation coefficients ranged from 0.52 to 0.97 for the different domain of the ASI with higher endorsement of problems in the self-administered than clinician administered version in most domains. Conclusion: The self-administered ASI is a valid alternative to the clinician-administered ASI and it saves valuable time especially in resource-constrained settings.

Introduction

The use of psychoactive substances is a ubiquitous problem globally with alcohol and substance use disorders accounting for over 20 per cent of Disability Adjusted Live Years caused by mental and substance use disorders, next only to depressive and anxiety disorders.[1] Substance use disorders are common problems in Nigeria, and the most commonly used substances include alcohol, cannabis, tobacco, and sedatives.[2],[3],[4] A hospital-based study in northeast Nigeria suggests that tramadol is also commonly abused with up to about 50% of patients using it.[5]

Substance use disorders are chronic and relapsing conditions because of which patients with addiction may develop various complications and problems that require comprehensive evaluation and assessment.[6],[7] Medical problems affecting many organ systems as well as psychiatric disorders have been documented among patients with substance use disorders.[8],[9],[10],[11] Patients with these disorders have problems in various areas including physical and mental health, legal and employment domains that are associated with drug and alcohol abuse. Evaluating patients for these problems is an invaluable aspect of addiction treatment that allows for various domains of problems to be elicited with a view to giving patients a holistic treatment. Indeed evidence is unequivocal in suggesting that identifying, evaluating, and attending to these myriad problems improve the outcomes of addiction treatment.[12],[13]

A number of instruments are currently in use for the evaluation of patients with substance abuse such as Addiction Severity Index (ASI),[14],[15],[16] Global Appraisal of Individual Needs,[17] and Maudsley Addiction Profile.[18] The ASI is the most widely used worldwide for treatment planning and outcome evaluation. It is a clinician-administered (CA) multidomain instrument consisting of seven domains (legal status, family/social status, drug use, alcohol use, medical status, psychiatric status, and employment status). It has been validated in different languages and it is being used in addiction treatment in many countries of the world including Nigeria.[19],[20],[21],[22]

Other formats of the ASI, which include the self-report form and the computer-based or telephone-based interactive voice...
