Provincial alcohol index and its relationship to alcohol-related harm in Thailand: implications for subnational alcohol policy development

Table 1 National estimates and a provincial example of five indicators and PAI scores

	National estimates			Bangkok’s estimates
	Average	Minimum	Maximum	Actual value	Method 1	Method 2	Method 3
Indicator
Prevalence of adult drinkers	0.299	0.022	0.545	0.212	0	0.212	0.364
Prevalence of underage drinkers	0.127	0.070	0.332	0.074	0	0.074	0.224
Proportion of regular drinkers	0.558	0.363	0.727	0.572	1	0.572	0.575
Proportion of binge drinkers	0.164	0.030	0.353	0.184	1	0.184	0.477
Proportion of drink-drivers	0.347	0.121	0.629	0.121	0	0.121	0
PAI score					40.0	23.3	32.8

Note: The PAI scores were scaled up from 1 to 100. For method 3 calculation using Bangkok as an example, score for the indicator of adult drinker prevalence is that (Bangkok actual value – minimum value)/(maximum value – minimum value) = (0.212–0.022)/(0.545–0.022) = 0.363. (The numbers in Table 1 may be different from calculation due to rounding methods.)
