Spousal Correlation of Mental Illness (EXCERPT)

Assortative Mating in Mental Health

• People tend to select partners who are consciously or unconsciously similar to themselves in profound ways that reflect their essence and identity, including mental health status. Thus, individuals with mental illness are more likely to partner with others who have similar predispositions or conditions. This phenomenon is described as assortative mating. [00:00]

Filtering Mechanism in Partner Selection

• There exists a filtering mechanism where people tend to exclude partners who are dramatically different from themselves, leading to couples initially being similar in mental health traits. This similarity sets the stage for shared vulnerabilities within the relationship. [00:25]

Impact of Partner’s Mental Health on Specific Disorders

• When one partner has a psychiatric condition such as personality disorders, schizophrenia, or bipolar disorder, they tend to select partners who have latent vulnerability to mental illness. However, the specific type of mental illness that develops in the partner depends largely on the other partner’s condition. This indicates a contagion effect influencing the specificity of the mental disorder rather than a general vulnerability. [00:50]

Contagion Effect and Specificity of Mental Disorders

• The specificity of the mental health disorder a person develops is influenced by their partner’s mental health condition, meaning a narcissistic partner increases the likelihood of narcissism in the other partner, while a partner with a mood disorder increases the likelihood of the same mood disorder. This suggests that partners play a determining role in shaping specific psychiatric outcomes. [01:25]

Genetic vs Environmental Influences on Mental Illness

• Genetics provide a hereditary predisposition to general susceptibility to mental illness but do not determine which specific disorder will manifest. The environment, particularly significant long-term social exposure to others with specific psychiatric conditions, mainly influences the type of mental illness developed. This highlights the interaction between genetic vulnerability and environmental factors, emphasizing the role of partner influence in mental health outcomes. [02:05]
