Week 9.1 Gambling Comorbidities and Clinical Implications

Introduction to Gambling Comorbidities

The correlation between gambling problems and mental illness is a significant challenge for clinicians. Individuals presenting with gambling disorders often exhibit high prevalence rates of other mental health issues, which can frequently be undiagnosed. Understanding these comorbidities is essential for determining where to assess problem gambling and how to design mental health services.

Conceptual Issues: Causality and Diagnosis

A primary issue in studying comorbidity in addiction is the direction of causality. This involves determining to what extent comorbid conditions are the cause or the consequence of gambling activities.

• Primary versus Secondary Diagnosis: In some instances, gambling is the primary problem driving secondary issues such as depression or anxiety. Conversely, gambling may be a secondary problem built upon existing psychological conditions.

• Clustering of Conditions: Multiple comorbid conditions often occur together. It is rare to find a patient suffering from only a single isolated problem; typically, conditions such as depression and anxiety cluster alongside the gambling disorder.

Selection versus Exposure Effects

There are two main conceptual effects used to explain why certain populations develop gambling problems:

1. Selection Effects: This theory posits that individuals with pre-existing conditions—including genetic and neurophysiological differences or psychological vulnerabilities—are more prone to addiction. In this view, gambling is a coping mechanism for existing problems rather than the cause.

2. Exposure Effects: This theory suggests that an otherwise normally functioning person may become a problem gambler simply through exposure to the activity.

Research suggests that both factors are likely at play. For example, recent SOUTH AUSTRALIA prevalence studies indicate that internet gambling is associated with higher problem rates. While this may imply it is a more "dangerous" product, it may also be a selection effect, as internet gamblers tend to be younger males with higher impulsivity and pre-existing risk factors. Such individuals often seek a wider range of activities to achieve a thrill, a pattern seen across other addictions like drug use and sex addiction.

Stakeholder Perspectives and the Interactionist View

Different stakeholders hold varying views on the cause of gambling problems:

• The Industry View: Often emphasizes the selection effect and "individual responsibility." They argue that the product (e.g., poker machines) is not the problem, but rather the individuals using them are blaming the machines for their own pre-existing issues.

• The Left-Wing/Marxist View: Argues that people are helpless victims of capitalist consumer culture and that the products are designed to take money from ill-informed consumers.

• The Psychological/Medical View (Interactionist): This is considered the most sensible view, suggesting an interaction between product characteristics and individual traits.

  • Product Factors: Certain features make products more addictive. For example, the speed of poker machines (electronic gaming machines or EGMs) and the ability to spend money quickly increases the probability of impaired control.

  • Individual Factors: Because relatively few people out of the thousands who play actually develop problems, individual motivation and help-seeking behaviors are critical for recovery.

Australian Evidence of Temporal Sequencing

A study funded by Gambling Research Australia examined $267$ treatment-seeking gamblers to determine when comorbid problems emerged.

• Gender Differences in Causality:

  • Men: Generally report that comorbidities occur after the gambling problem. For men, $48\%$ said problem gambling came first, $23\%$ said they occurred simultaneously, and $30\%$ said gambling followed depression.

  • Women: Often use gambling to cope with pre-existing issues. Specifically, $61\%$ of women reported being depressed before the onset of problem gambling. This is consistent with research showing women often use EGMs (pokies) as "escape activities" to distance themselves from existing life problems.

• Smoking: Smoking typically precedes the gambling problem. Approximately $60\%$ of problem gamblers are smokers, indicating a vulnerability to multiple forms of addiction.

Categories and Prevalence of Comorbidity

Comorbidity is generally categorized into three areas: affective disorders (anxiety/depression), cross-addictions (drugs/alcohol), and psychiatric or personality disorders. A review by Lorraine Zetel (2011) published in Addiction provided the following statistics for problem gamblers:

• Nicotine dependence: $60\%$

• Anxiety disorders: $40\%$

• Major depression: $23\%$ (though general depression levels may be as high as $80\%$

• Alcohol disorders: approximately $33\%$ ($1/3$)

• Personality disorders: approximately $33\%$ ($1/3$)

The Pathways Model of Problem Gambling

The Blaszczynski and Nower pathways model identifies two significant routes to problem gambling involving comorbidity:

1. The Vulnerability Pathway: Driven by depression, anxiety, and a need for escape. Jerome Jacobs’ "Generalized Theory of Addictions" suggests gambling is a psychological addiction for these individuals. They often have histories of early abuse, trauma, family dysfunction, and an emotional avoidant-based coping style. These individuals gravitate toward "escape" activities like EGMs.

2. The Pathology Pathway: Involves individuals with physiological or neurophysical differences. They often exhibit antisocial personality disorders and high impulsivity. They may make impulsive decisions and misread information in a way that confirms their belief that they can win.

South Australian Study on Vulnerability

A study of nearly $200$ regular community gamblers (primarily EGM users) using the Problem Gambling Severity Index (PGSI) found:

• Systematic increases in depression, anxiety, and stress as gambling risk levels increased.

• Higher risk gamblers were more likely to report childhood trauma, including the death of parents, marital stress, domestic violence, and psychological, physical, or sexual abuse.

• Dissociation: This refers to the tendency to lose track of reality while gambling. The study found that trauma history leads to psychological vulnerability, which increases the need for escape/sensations (dissociation), ultimately leading to problem gambling.

The Pathology Model and Psychiatric Assessment

A study of $150$ regular EGM gamblers using detailed psychiatric assessments found significant differences between pathological and non-pathological gamblers:

• Suicidality: Pathological gamblers have much higher rates of suicidal ideation and intent. CycMed (North Terrace) operates a suicide treatment service specifically because of this link.

• Clinical Disorders: High rates of Bipolar disorder, panic disorders, and social phobias.

• Overall Pathology: Approximately $91\%$ of the help-seeking sample had evidence of a psychiatric disorder, whereas only $9\%$ had no evidence of one.

• Personality Clusters: Strong markers for paranoid, schizotypal, and antisocial personality disorders were found in the pathological group.

Borderline Personality Disorder (BPD) and Gambling

BPD is a common, often undiagnosed, comorbid condition in gambling clinics. It is characterized by:

• Problems with emotional regulation.

• Persecution and conspiracy complexes.

• Bouts of extreme optimism and pessimism (vacillation of emotion).

• Perfectionism and obsessiveness.

Cognitive Links: Individuals with BPD symptoms often engage in "black and white" thinking and are prone to magical thinking and superstitious beliefs. The study found that BPD symptomology correlates with irrational gambling beliefs and "delusion-proneness." This mirrors patterns seen in ADHD (resistance to punishment) and Autism Spectrum Disorder (fixed obsessive thinking and systems for winning).

Clinical and Service Delivery Implications

The high rate of comorbidity necessitates a multidisciplinary approach to treatment.

1. Integrated Services: Successful services require psychiatric input and a strong clinical psychology focus to address the underlying depression, anxiety, or personality disorders driving the gambling.

2. Screening: Mental health services and drug/alcohol services must routinely screen for problem gambling, as about $25\%$ of those populations may have a gambling problem.

3. Cross-Referral: Linkages between dedicated gambling services and general mental health services are essential to ensure all aspects of the patient's condition are treated simultaneously.
