Strength and Limitation
The key strength of this study lies in the fact that it is the first
empirical study assessing quality of life among quarry workers across
Nigeria using a valid and reliable tool. The use of standard tool is the
major strength of this study in that it avoided trial and error chance
and its findings are reliable [45]. It is also the first empirical
study that modelled the socio-demographic factors, workplace factors and
WRMSDs with quality of life among the quarry workers in Nigeria.
The key limitation of this study lies in the cross-sectional design
employed which may not have allowed for detailed exploration of the
quality of life among the quarry workers. This study also focused on the
quarry workers in Ebonyi state, Nigeria and therefore, the result may
not be generalized to other quarry workers in other states in Nigeria.
