Gambling Disorder Identification Test (PGSI)
Gambling Disorder Identification Test · Also known as: Problem Gambling Severity Index, PGSI, Gambling Disorder Screen
The PGSI (Problem Gambling Severity Index) is a 9-item self-report questionnaire measuring problem gambling severity and gambling disorder risk. Developed by Ferris and Wynne in 2001 for the Canadian Centre on Substance Use and Addiction, it is one of the most widely used screening tools for gambling disorder in English-speaking countries. The PGSI assesses gambling frequency, loss of control, negative consequences, and harm from gambling. It is available freely and has been translated into multiple languages.

When to use it
The PGSI is recommended for population screening of gambling disorder, assessment in treatment-seeking samples, and monitoring of treatment outcome. It is appropriate for adolescents (15+) and adults. The PGSI is particularly valuable in primary care, emergency departments, and mental health clinics as a brief screening tool to identify individuals with gambling problems. It is less appropriate as a diagnostic tool on its own (clinical interview is required for diagnosis) or as a detailed assessment of gambling cognitions and motivations (specialized gambling disorder interviews provide more detail).
Strengths & limitations
- Extreme brevity — 9 items, 3–5 minute completion, suitable for rapid screening in high-volume settings.
- Practical public domain — free, no licensing fees, available in printed form and online.
- Strong psychometric properties — good internal consistency (Cronbach's α ≥ 0.84), test-retest reliability (r ≥ 0.80 over 2–4 weeks), and external validity against gambling disorder diagnosis.
- Clear classification system — straightforward score ranges identifying non-problem, low-risk, moderate-risk, and problem gambling.
- Extensively translated and validated — 20+ language versions and validation across diverse countries and cultures.
- Does not diagnose gambling disorder formally — requires clinical interview to confirm DSM-5 criteria (loss of control, tolerance, withdrawal, continuation despite harm, deception/concealment).
- Limited assessment of motivations — does not distinguish escape-motivated gambling from thrill-seeking or social gambling; all may score similarly despite different etiologies.
- Potential underreporting — social desirability bias and shame may lead to underreporting of gambling problems, particularly in conservative cultural contexts.
- Does not assess gambling-related cognitions — does not measure irrational beliefs (near-miss fallacy, illusion of control) that maintain gambling disorder.
- No assessment of comorbidity — does not evaluate depression, anxiety, substance use, or other disorders often co-occurring with gambling disorder.
Frequently asked
I scored 4 on the PGSI. Do I have gambling disorder?
A PGSI score of 4 suggests moderate-risk gambling. This does not diagnose gambling disorder but indicates concerning patterns warranting attention. Examine: Are you unable to control how much you gamble? Are you chasing losses (gambling more to recover money)? Is gambling affecting your finances, relationships, or work? If yes to these, discuss with a healthcare provider. Possible interventions include setting betting limits, self-exclusion programs, or brief counseling.
What's the difference between PGSI and a diagnosis of gambling disorder?
PGSI is a screening tool measuring gambling problem severity (0–27 score). Gambling disorder is a clinical diagnosis requiring: loss of control, tolerance (needing to gamble more), withdrawal symptoms, chasing losses, deception/concealment, repeated unsuccessful attempts to cut back, and risk of relationship/job/education loss. PGSI ≥8 is necessary but not sufficient for diagnosis; a clinical interview confirming DSM-5 criteria is required for formal diagnosis.
My partner scored 15 on the PGSI. What should I do?
A PGSI score of 15 indicates probable problem gambling. Encourage your partner to seek professional assessment with a gambling disorder specialist. Treatment options include cognitive-behavioural therapy, financial counseling, self-exclusion programs, and support groups (Gamblers Anonymous). Family involvement (family therapy, education about problem gambling) can be helpful. Consider seeking family therapy to address relationship and financial consequences.
Is the PGSI available in my language?
The PGSI has been translated into 20+ languages including Spanish, French, German, Portuguese, Italian, Dutch, Swedish, Chinese, Japanese, Korean, Polish, and others. Check the original publication (Ferris & Wynne 2001) or contact gambling research centers for available translations and validated versions in your language.
