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 = 0.87
Specificity = 0.96
Positive predictive value = 0.74
Negative predictive value = 0.98
A sensitivity of 87 per cent suggests that the BBGS detects 87 per cent of people with problem gambling (true positives) but that 13 per cent go undetected (false negatives).
A specificity of 96 per cent suggests that the BBGS correctly reports 96 per cent of people without problem gambling as negative (true negatives) but that three per cent without problem gambling are incorrectly identified as positive (false positives).
A positive predictive value of 0.74 suggests that 74 per cent of people who screen positive on the BBGS will be identified as a problem gambler.
A negative predictive value of 0.98 suggests that 98 per cent of people who screen negative on the BBGS will be correctly identified as a non-problem gambler.
