Everyday young people are introduced to alcohol and this early introduction to alcohol consumption eventually leads to abuse. The burden of diseases caused by the abuse of alcohol, the harm done to their social life and the decimation of their finances are some of the motivation for this work. This paper aims at providing an alternative and better approach to solving the problem of alcohol addiction using behavioral change theories and persuasive software. It has been found that many people are extremely open and motivated when talking to a computer about personal problems. The system is designed making with human behaviour theories; Trans theoretical Model (TTM), Goal Setting Theory, Reinforcement Theory, Social Learning Theory and Knowledge-Attitude-Behaviour Model (KAB). This was done bearing in mind that proper understanding of human behaviour theories enables designers to know which theory to apply and how the application of the theory will help the user. In addition to human behaviour theories, persuasive strategies were incorporated in the design of the system. Object-Oriented Analysis and Design Methodology (OOADM) was employed. Implementation was achieved using Hypertext Preprocessor scripting language and MySQL server. The resulting system is a web-based application that provides users with not just the requisite information needed about alcohol addiction but also exercises and activities that persuades them to think deep about their addiction and work hard towards overcoming them.
