Describe the diathesis-stress model. Use it to explain how one identical twin can suffer from clinical depression while the other twin does not.

Solutions

Expert Solution

The Diathesis-stress model explains that the psychological disorders emerge when a diathesis [ biological predisposition to the disorder] is set off by a stressful situation. Three components:-

  • There is a diathesis
  • Diathesis carrying vulnerability
  • Presence of pathogenic stressors.

One twin develops clinical depression and other twins do not.

Both have the same biological predisposition towards developing a disorder, but there is a difference in a stressful event[pathogenic stressors]. One twin might be exposed to a stressful event but another might not be.

A study comparing children’s reading age (in months) was developed using identical twin toddlers. One set of 6 twins played for 2 hours each day with educational toys (experimental group), the corresponding set of 6 twins played for 2 hours each day with non-educational toys (control group). The mean difference in reading age between the experimental group and control group of 6 sets of twins was -2.33 months and the standard deviation of the sample difference was 2.16 months. Set...
