Safety Culture State Review Index calculation

The calculation of the Safety Culture State Review – Index is based on an easy-to-use calculation formula. In the first step, an index is calculated for each individual subject area. In the second step, an average value is calculated across all 20 subject areas. This value is defined as the Safety Culture State Review – Index.

Step 1. Calculation of the index for a subject area – Index(i)

To calculate the index value for a subject area – Index(i) -, the following calculation formula is to be used:

Index(i) = (count(A) * 3pt + count(B) * 5pt + count(C) * 8pt + count(D) * 0pt) / (count(A) + count(B) + count(C) + count(D))

Example: Total participants: 25, of this: count(A): 10, count(B): 4, count(C): 2, count(D): 9

Index(i) = ((10 * 3) + (4 * 5) + (2 * 8) + (9 * 0)) / 25
Index(i) = 66 / 25 = 2,6

Step 2. Calculation of the Safety Culture State Review – Index

In order to calculate the Safety Culture State Review – Index, the average is formed across all 20 subject areas.

Index = average(Index(1) … Index(20))

Example – Index calculated for each subject area (1 to 20) acc. to step 1 –
(1): 4, (2): 4.9, (3): 2.2, (4): 4.2, (5): 2.4, (6): 4.3, (7): 2.9, (8): 3.7, (9): 4.3, (10): 3.5, (11): 3.8, (12): 3.7, (13): 3.9, (14): 3.4, (15): 2.9, (16): 3.7, (17): 4.9, (18): 2.3, (19): 1.8, (20): 4.3

Index = average(4, 4.9, 2.2, 4.2, 2.4, 4.3, 2.9, 3.7, 4.3, 3.5, 3.8, 3.7, 3.9, 3.4, 2.9, 3.7, 4.9, 2.3, 1.8, 4.3) = 3.6
