This cross sectional study investigated the test –retest reliability of the Malay Version Job Content
Questionnaire (M- JCQ) among electricity linemen. The M-JCQquestionnaire was administered to 10
electricity linemen working in private sub-contract company. The data were collected at two occasions
with one week interval of time between each sessions. Intraclass Correlation Coefficient (ICC) and Bland
Altman plot were used to analyze the reliability of the M-JCQ. The ICC for the ‘psychological demand’,
‘decision latitude’, ‘work related social support’ and ‘job insecurity’ scale were 0.96, 0.52, 0.99 and 0.55
respectively. The Bland Altman plot indicated that the tests and retest score for all the four scales had an
acceptable agreement. These findings indicated that the M- JCQ is reliable and consistent for assessing
work related psychosocial risk factors among electricity linemen.
