The study, conducted by Dr Demid Getik, explores how mental health is related to income make-up within couples by examining the link between annual income rises for women and the number of clinical mental health diagnoses over a set period of time.
The study finds that as more women take on the breadwinner role in the household, the number of mental health related incidences also increases.
As wives begin earning more than their husbands, the probability of receiving a mental health diagnosis increases by as much as 8% for all those observed in the study, but by as much as 11% for the men.
That assumption is based upon the idea that working with a broad range of strangers means you can’t trust people specifically, so you have to work towards your goals. From that you will end up cooperating naturally with anyone who shares your goals, but you will also have to compete fiercely with those who have goals antagonistic to your own.
