Description: Read just the title of the article linked below. Now, what questions or hypotheses pop up for you with just the title in mind? If you have had a psychology or a statistics course you will recognize the title as a typical example of a statement of correlation. Psychiatric disorders and type 2 diabetes, the title suggests, are related to one another, or they co-occur. Interesting but what questions do you have? How about “But why?” Now there is the important question. Think about what you can come up with in the way of possible answers to the “but why” question and then read the article linked below to see if your hypotheses match any of those examined by the researchers.

So, having read the linked article are you satisfied that you know have a clear answer to the “but why?” question?  The research in question was a meta-analytic study in that it looked at what 245 separate studies had to say about the relationship between the disorder or disorders they studied and type 2 diabetes. While a number of disorders were linked to levels of type 2 diabetes above the population average the strongest relationship (40%) was seen in relation to sleep disorders. The main focus on sleep disorders from that point on in the article suggests that sleep difficulties may be the critical point of correlational connection, though it does not clearly suggest a causal direction hypothesis: does lack of good sleep cause type 2 diabetes or does type 2 diabetes cause a lack of sleep? And what about the other disorders with elevated levels of type 2 diabetes? Given these uncertainties it is fitting that their closing statement I a version  of “further research is needed”.

Questions for Discussion:

  1. Are type 2 diabetes and psychological disorders related and if so to what extent?
  2. Why might such correlations exist?
  3. What sorts of studies need to be done if we are to be able to unpack and better understand the causal factors involved in the observed relationships between type 2 diabetes and psychological disorders?
