The Victorian Gambling Screen: reliability and validation in a clinical population

Area of Science:

• Psychometrics
• Clinical Psychology
• Addiction Research

Background:

• Reliability and validity are crucial for accurate assessment tools in diverse settings.
• The Victorian Gambling Screen (VGS) is a measure used in problem gambling assessment.
• Specific validation data for the VGS, especially its Harm to Self (HS) sub-scale, is needed.

Purpose of the Study:

• To evaluate the reliability and validity of the Victorian Gambling Screen (VGS).
• To specifically assess the reliability and validity of the Harm to Self (HS) sub-scale of the VGS.
• To explore the utility of the VGS in specialist problem gambling treatment services.

Main Methods:

• Sixty-seven gamblers in a specialist treatment service were assessed.
• The Victorian Gambling Screen (VGS) was administered alongside a validated clinical interview.
• Internal consistency (Cronbach's alpha) and convergent validity were examined.

Main Results:

• The VGS demonstrated strong internal consistency (Cronbach's alpha = .85).
• The Harm to Self (HS) sub-scale showed excellent internal consistency (Cronbach's alpha = .89).
• Satisfactory convergent validity was evidenced by moderate correlations with the South Oaks Gambling Screen and other psychopathology measures.

Conclusions:

• The Victorian Gambling Screen (VGS) is a reliable and valid measure for assessing problem gambling.
• The Harm to Self (HS) sub-scale is a reliable component of the VGS.
• The VGS is appropriate for use in clinical settings for problem gambling assessment.
