Numerous studies have shown that children of divorced parents are more likely to get divorced when compared to those who grew up with parents who remained married.
But this pattern may not hold true for adopted children, a new study suggests.
According to the research, genetic factors are the primary explanation for the divorce trend, and the new findings could have implications for the advice provided by marriage counselors or therapists.
The study's findings suggest that, instead, it might be useful for therapists to target some of the more basic personality traits that previous research has suggested are genetically linked to divorce - for example, traits such as high levels of negative emotionality and low levels of constraint. 'For example, other research shows that people who are highly neurotic tend to perceive their partners as behaving more negatively than they objectively are [as rated by independent observers],' Dr Salvatore said. 'So, addressing these underlying, personality-driven cognitive distortions through cognitive-behavioral approaches may be a better strategy than trying to foster commitment.'
