ABSTRACT

Various research methods such as observation, interview, survey, experiment, or quasi-experiment have been utilized to advance the literature in occupational health psychology (OHP) with the goal of improving the quality of work life and promoting healthy workplaces (Chen, DeArmond, & Huang, 2007). Among these methods, experiments are likely considered the most robust method to investigate causal relationships between variables of interest. The unique strength of experiments is attributed to the fact that “causes” are manipulated (either deliberately or not) and their “effects” or “impacts” are systematically assessed in a controlled setting.
