PTSD and Alcoholism: Correlation, Trauma, and Co-Morbidity
This research proposal examines the relationship between post-traumatic stress disorder (PTSD) and alcoholism/addiction through a comprehensive literature review. The paper surveys existing studies to evaluate whether a direct correlation exists between PTSD and alcohol or substance abuse, with particular attention to the role of trauma, childhood abuse, gender differences, emotional deficits, and genetic and environmental influences. Evidence drawn from multiple peer-reviewed studies consistently supports the hypothesis that PTSD and alcoholism co-occur at significantly elevated rates compared to the general population. The paper concludes by proposing a quantitative correlation study using randomized sampling from alcohol treatment programs to establish empirically grounded, externally valid findings on this co-morbid relationship.

What makes this paper effective
- The paper organizes a broad literature review into clearly delineated thematic subsections — trauma, childhood abuse, gender, emotion, and genetics — allowing cumulative evidence to build toward a well-supported conclusion.
- The author explicitly states both a directional hypothesis and a null hypothesis early in the paper, grounding the literature review in a clear research question and maintaining scientific rigor throughout.
- Contradictory evidence (e.g., Op Den Velde et al., 2002) is acknowledged and contextualized rather than dismissed, demonstrating intellectual honesty and strengthening the overall argument.
Key academic technique demonstrated
The paper demonstrates effective use of a hypothesis-driven literature review. Rather than summarizing sources in isolation, the author frames each study in relation to the central research question — whether PTSD and alcoholism are causally or correlationally linked — and uses the cumulative findings to justify a proposed quantitative methodology. This technique shows how literature reviews can function as both evidence synthesis and research design rationale.
Structure breakdown
The paper follows a formal research proposal structure: an abstract is followed by an introduction that states the hypothesis, a background section establishing the problem's significance, a methods section outlining the proposed study design, a multi-part literature review organized by theme, and a concluding section on assessment models and validity. This progression moves logically from problem identification through evidence review to proposed empirical action.
Introduction
The purpose of this study is an examination of the relationship between post-traumatic stress disorder (PTSD) and alcoholism/addiction, in an effort to determine whether a correlation exists between the two conditions.
There is a large body of evidence suggesting that alcohol abuse is common in patients diagnosed with PTSD (Thornton, 2003; Weinstein, 1999; Jaycox et al., 2004). Much of the research conducted in the past has focused on the co-morbidity of traumatic disorders, other psychological disorders, and the presence of alcohol abuse or other substance abuse problems in patients seeking treatment for alcohol abuse.
This study is important because it will link past research and data in order to develop a scientifically grounded explanation for the co-existence of such disorders, further clarifying the body of research conducted thus far. A majority of the evidence available on PTSD and addiction-related disorders is qualitatively based. The intent of this research is to find empirically based relationships that demonstrate a statistical link between PTSD and addiction; thus, the study will be quantitatively based.
The researcher will examine the historical literature available with regard to PTSD and alcoholism/addiction in order to derive a hypothesis grounded in theory and supported by scientific data. Based on the preliminary results of the literature review, the researcher proposes the following:
Hypothesis A: A direct correlation between post-traumatic stress disorder and alcoholism/addiction exists.
Null Hypothesis: A direct correlation between post-traumatic stress disorder and alcoholism/addiction does not exist.
The proposed hypotheses are grounded in a large body of evidence suggesting a direct link between alcoholism and other addictive behaviors and the occurrence of traumatic experiences in youth and/or adulthood (Thornton, 2003; ISTSS, 2003; Weinstein, 1999; Jaycox, Ebener, Damesek & Becker, 2004).
The author proposes that a correlation does exist between alcoholism/addiction and post-traumatic stress disorder. To confirm this hypothesis, the author proposes an in-depth examination of the historical literature and case studies available on PTSD and alcoholism/addiction — specifically, whether a relationship exists between the two, and if so, what the extent of that relationship is.
This research will help confirm the relationship that may exist between PTSD and substance abuse, and will hopefully assist researchers and medical authorities in developing more targeted treatment programs that acknowledge the relationship (if any) between alcohol or chemical dependency and post-traumatic stress disorder.
Background to the Problem and Statement of the Problem
Studies suggest that the use of alcohol or other drugs may provide patients dealing with trauma with a temporary distraction and relief from the thoughts, feelings, and negative emotions associated with a traumatic event (ISTSS, 2003), and that substance abuse is generally chronic because the relief provided is only temporary. There is further evidence to suggest that alcohol abuse may be utilized as a means of self-medication against traumatic memories and experiences (ISTSS, 2003; Thornton, 2003).
Given this information, it is critical to examine whether a specific relationship exists between substance abuse and PTSD in order to identify treatment methods most likely to benefit patients demonstrating co-morbid PTSD and substance abuse problems.
The aim of this study is to assess whether a correlation exists between alcohol/substance abuse and PTSD. Studies suggest that patients with PTSD are diagnosed with lifetime alcoholism at a rate two to three times that of the typical population, and that patients seeking treatment for alcoholism are three times more likely to demonstrate symptoms of PTSD (Thornton, 2003; Kessler, Sonnega, Bromet, Hughes & Nelson, 1995).
Research also suggests a strong link between exposure to trauma and substance abuse problems (ISTSS, 2003). Trauma-related disorders including PTSD are found to occur more frequently in people with substance abuse disorders such as alcohol abuse (ISTSS, 2003). Gender links have also been associated with PTSD and alcoholism, with some studies confirming that women are five times more likely to receive a dual diagnosis of alcoholism and PTSD (Thornton, 2003; Kofoed, Friedman & Peck, 1993).
More than 50% of adults with co-occurring alcohol abuse problems and PTSD are also thought to have other serious behavioral or psychological problems, including anxiety disorders, mood disorders, disruptive behavioral disorders, and other addictive behaviors (ISTSS, 2003).
Methods
A comprehensive literature review will be compiled examining the nature of PTSD and substance abuse problems. Specifically, the research will first broadly examine PTSD with regard to alcoholism, then investigate the role of trauma in the co-morbidity of PTSD and alcoholism, then examine childhood influences and gender differentiation in patients with a dual diagnosis, then attempt to identify whether a relationship exists between PTSD, alcohol abuse, and emotional disturbances, and finally examine whether genetic and environmental factors influence the relationship between alcohol abuse and PTSD.
There is a large body of evidence suggesting that a quantitative approach to behavioral analysis and PTSD is appropriate (McKeehan & Martin, 2002; Weinstein, 1999). A majority of the studies conducted on PTSD and substance abuse are qualitatively based (Jaycox, Ebener, Damesek & Becker, 2004; Langeland, Van Den Brink & Draijer, 2002; Brown, 2001). This study aims to provide more empirical data related to the phenomena of alcoholism and PTSD; thus, a correlation study will be conducted.
The author proposes development of a questionnaire to be distributed to patients attending alcohol treatment programs. The questionnaire will assess whether patients have experienced some level of trauma during their lives that may be directly linked to their substance abuse problems. It will also investigate whether patients undergoing treatment for alcohol abuse demonstrate underlying PTSD symptoms, and whether patients with co-morbid PTSD are more likely to relapse or fail to complete a program than those without a dual diagnosis. The research proposes that anonymity be provided to all participants given the sensitive nature of the topics being discussed.
