Document Summary

Research on etiology in psychopathology: genetically informed designs. Problem: disorders are likely caused by multiple (unknown) genesnew approach: genome-wide association. Problem: people probably inherit vulnerability genes not disorder genes (endophenotypes); more and more people are looking for genes that shape depression not ones that cause depression. Problem: gxe may be present (diathesis stress model)aka gene environment interaction is an example of a diathesis stress model. Observational measures are probably much better to use than questionnaires because questionnaires are bias. If negative outcomes decrease based on an intervention/prevention strategy, causal mechanism can be supported. Prevention designs are generally rare (go in before an try and prevent depression by trying to change children"s attitudes before they develop depression and follow them throughout life) Non clinical samples: mood induction studies where you make one group sad and one happy aka changing their moods and implying results. Prior to 1980"s, quality of info was poor.
