Industrial Relations Event Scale – IRES
Measures the occurrence and perceived positive or negative impact of stressful industrial relations events in the workplace.
Scale Development & Technical Details
Scale Overview
The Industrial Relations Event Scale – IRES was developed by E. Kevin Kelloway, Julian Barling, & A. Shah (1993). It is designed to measure Industrial relations stress. The scale is intended for use with Working adults.
Scale Structure
This instrument consists of 25 items organized into 3 factors/subscales: Occurrence of Industrial Relations Events, Perceived Negativity of Events, Positive Perception of Industrial Relations.
| Factor / Subscale | Items | N |
|---|---|---|
| Occurrence of Industrial Relations Events | 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25 | 25 |
| Perceived Negativity of Events | 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25 | 25 |
| Positive Perception of Industrial Relations | 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25 | 25 |
Response Format
Respondents rate each item using a custom response format.
Response anchors: -3 = Extremely negative impact, -2 = Moderate negative impact, -1 = Mild negative impact, 0 = Occurred, but no impact, 1 = Mild positive impact, 2 = Moderate positive impact, 3 = Extremely positive impact.
Scoring
Items are scored by subscale, with each subscale sum representing a distinct dimension.
Total scores range from 0 to 25. Interpretation guidelines:
- Low exposure to industrial relations events: 0 – 5
- Moderate exposure to industrial relations events: 6 – 15
- High exposure to industrial relations events: 16 – 25
Psychometric Properties
Internal Consistency: The scale has demonstrated good to excellent internal consistency with reported Cronbach’s alpha values of N/A (customary internal consistency measures are inappropriate due to the life events methodology).
Administration
The scale is self-administered and typically takes approximately 5 minutes to complete. It can be administered individually or in group settings. No special training is required for administration.
