Functional Analysis of Substance Abuse Behavior: A Case Study
This paper applies functional assessment and functional analysis frameworks to substance abuse behavior, using a real case study involving a young man with chronic alcohol dependence and a history of family violence. Drawing on the World Health Organization's definition of substance abuse and established behavioral assessment procedures, the paper walks through the five core steps of functional analysis — interview, direct observation, experimental manipulation, summary, and behavioral lesson plan — across two related behaviors: the subject's assault on his father, and his broader pattern of alcohol abuse. The analysis reveals deep-rooted antecedents including childhood trauma, parental alcoholism, domestic violence, and a diagnosis of chronic schizophrenia, and concludes with recommendations for treatment and intervention.

What makes this paper effective
- The paper grounds its case analysis in established behavioral science methodology, clearly defining functional assessment and functional analysis before applying them step by step.
- It maintains a parallel structure across both analyzed behaviors — assault and alcohol abuse — applying the same five-step framework consistently, which aids clarity and comparison.
- The paper integrates multiple sources of evidence (interview, direct observation, CCTV footage, psychiatric records) to support its functional summaries, demonstrating evidence-based reasoning.
Key academic technique demonstrated
The paper demonstrates applied case analysis using a structured behavioral framework. Rather than diagnosing by symptom, it identifies environmental antecedents and maintaining conditions for each behavior, then derives targeted interventions — a hallmark of applied behavior analysis methodology.
Structure breakdown
The paper opens with a definitional and statistical introduction to substance abuse, then defines functional assessment and functional analysis as methodological tools. It proceeds through two sequential functional analyses — first the assault incident, then the broader alcohol dependence — each subdivided into interview, direct observation, experimental manipulation, summary, and behavioral lesson plan. The paper closes with prognosis and treatment considerations, including the limitations posed by chronic schizophrenia.
Introduction to Substance Abuse and Functional Assessment
The World Health Organization (2015) defines substance abuse as the harmful use of psychoactive substances such as drugs and alcohol, which can lead to dependence and a loss of control. Dependence can be physiological, cognitive, or behavioral, to the point of neglecting important responsibilities and relationships (WHO, 2015). In the United States, substance abuse costs more than $700 billion a year, accounting for crime, healthcare, and lost work productivity (NIH, 2015).
Functional assessment consists of procedures that aim to identify the cause or causes of maladaptive or socially unacceptable behavior in order to control or reduce it (Carbone & Zecchin, 2015; Hanley et al., 2003; CECP, 2001; EOHHS, 2015; Webster, 2015; Maclino, n.d.; Opioidrisk, 2015). Assessment seeks out causes in the person's immediate environment and learning history. The findings of an assessment form the basis of an analysis of how the person learned or developed the maladaptive behavior and how his current environment supports or maintains it. Unlike a medical diagnosis, functional assessment does not classify behavior according to symptoms, but by its function. It then selects the appropriate and precise treatment or intervention to reduce that behavior (Carbone & Zecchin, 2015; CECP, 2001; EOHHS, 2015; Webster, 2015; Maclino, n.d.; Opioidrisk, 2015).
Functional analysis identifies the controlling environmental functions of a person's behavior (Carbone & Zecchin, 2015; Hanley et al., 2003; EOHHS, 2015; Webster, 2015). These functions are then manipulated in order to change the maladaptive behavior. A functional analysis concludes with the least restrictive and most effective interventions for reducing or modifying the maladaptive behavior. The five general steps used in functional analysis of behavior are: a functional interview with knowledgeable or involved persons, direct observation of the behavior, experimental manipulations, a summary, and a behavioral lesson plan. Functional analyses of two behaviors are illustrated below using an anonymized case involving a substance user and his father.
