The objective of the study
The study’s objective was to establish the risk factors for reduced cognition during midlife and the likely effects of working for long hours on the mental health of middle-aged people (Virtanen, Singh-Manoux, Ferrie, Gimeno, Marmot, Elovainio & Kivimäki, 2009, pp. 596).
Study design
The study employed the cohort study design.
Why this design was chosen (advantages and disadvantages).
The cohort study design is the ideal design to measure the effects of a suspected risk factor, and it allows for the selection of specific subjects exposed to a particular factor, in this case, middle-aged individuals. On the other hand, it forces a researcher to follow a large group of people for an extended period. Also, it is time-consuming and expensive as you have to test different variables from numerous subjects.
How participants were selected
The Whitehall II study recruited men and women thirty-five to fifty-five years old, working in London’s twenty Civil Service departments offices (Virtanen et al., 2009, pp.597).
