The perceived and predicted implications of psychiatric genetic knowledge among persons with multiple cases of depression in the family.

OBJECTIVE: Psychiatric genetic research raises hope regarding better treatment and prevention, but also regarding a possible de-stigmatizing effect of attributing mental illness to genetics. This study explores i) the impact on family relations of participating in a genetic study; ii) the impact of biogenetic attributions on perceptions of depression and stigma and iii) the perceived benefits and concerns regarding psychiatric genetic testing.
METHOD: Focus groups were conducted with 17 participants suffering from depression, with multiple cases of depression in the family, and previously participating in a genetic study.
RESULTS: Participating in a genetic study caused more openness about depression in most families. A biogenetic explanation of depression was perceived as having the potential of diminishing self stigma. Testing of self and children was widely accepted, whereas prenatal testing raised concern.
CONCLUSION: Persons suffering from depression may benefit from endorsing a biogenetic explanation, especially in relation to self-understanding and self-stigma.
