Interaction of gene x parenting style in predicting depression

This is the reason why parents play a significant role in influencing the well-being of children. Other than the interaction of parent’s work stress and child’s psychological adjustments, Ecological systems Theory of Development has expanded into many related fields like depression study. In fact, I remember a psychology research article in a local newspaper a few years ago, which reported that the main stressor of key person in adolescent is ironically from his/her mother. Personally, I agree with this because my mother always has the greatest demand/expectation from me in becoming an ideal individual.

Psychologist, Gerald Haeffel, and colleagues examined whether a gene associated with dopamine interacted with maternal parenting style to predict episodes of depression. The sample consisted of 177 male adolescents from a juvenile detention center in Russia. Depression was diagnosed by employing a structured diagnostic interview; while aspects of maternal parental rearing (i.e. physical punishment, hostility, lack of respect for the child’s point of view, and unjustified criticism in front of others) were assessed by a questionnaire. It was reported that neither genes nor maternal parenting style alone can be used to predict depression. However, depression can be determined by a combination of the following factors: (1) The male adolescents with especially rejecting mothers, and (2) a specific form of the dopamine transporter gene. Therefore, it is suggested that the use of psychosocial interventions to increase dopamine activity in the brain (Association for Psychological Science, 2008). Most importantly, we need to aware of the impact of parenting styles on parents as part of a child’s immediate environment.
