About the measure

A "yes" to any of the questions means that the person is at risk for developing a gambling problem; continue with full screen to assess risk level.

If negative, reinforce healthy decisions and continue with appointment.

Measure Characteristics

  • Sensitivity = 0.98
  • Specificity = 0.90
  • Positive predictive value = 0.54
  • Negative predictive value = 0.99

The high sensitivity and positive predictive value displayed by the five-item BPGS suggests that it is a quick and effective tool for identifying clients with any level of problem gambling.

  • A sensitivity of 98 per cent suggests that the BPGS detects 98 per cent of people with problem gambling (true positives) but that two per cent go undetected (false negatives).
  • A specificity of 90 per cent suggests that the BPGS correctly reports 90 per cent of people without problem gambling as negative (true negatives) but that 10 per cent without problem gambling are incorrectly identified as positive (false positives).
  • A positive predictive value of 0.54 suggests that 54 per cent of people who screen positive on the BPGS will be identified as a problem gambler.
  • A negative predictive value of .99 suggests that 99 per cent of people who screen negative on the BPGS will be correctly identified as a non-problem gambler.
