Insights
Spouses of individuals with mental health disorders, particularly serious conditions like schizophrenia, experience higher rates of stress, anxiety, and depression. These findings highlight significant within- and cross-disorder correlations in married couples.
Area of Science:
- Psychiatry
- Public Health
- Sociology
Background:
- Mental health disorders significantly impact relationships and are heritable.
- A notable prevalence of mental illness exists in spouses of individuals with mental health conditions.
- Understanding these correlations is crucial for family well-being.
Purpose of the Study:
- To assess within- and cross-mental health disorder correlations in husband-and-wife pairs.
- To quantify the increased risk of mental health issues in spouses based on the partner's diagnosis.
- To investigate the influence of specific mental illnesses on spousal mental health.
Main Methods:
- Cross-sectional study utilizing medical claims data (DMBA) and employee eligibility files (2020).
- Analysis of 21,027 contract holders (aged 18-64) and sub-analyses on 16,543 married individuals.
- Calculation of adjusted rates and rate ratios for stress, anxiety, and depression in spouses.
Main Results:
- Spouses of contract holders showed rates of stress (19.2%), anxiety (26.4%), and depression (23.6%) mirroring the contract holder's condition.
- The highest rates of spousal mental illness occurred when the contract holder had schizophrenia.
- Spousal mental illness rates were generally higher for wives of male contract holders compared to husbands of female contract holders.
Conclusions:
- Mental health disorders in spouses are elevated when the contract holder has a mental health disorder, especially severe ones.
- Significant within- and cross-disorder correlations were observed between partners.
- Findings have implications for relationship quality and the mental health of offspring.
Background:
Mental health disorders can adversely affect relationships and are heritable. Yet, there is a high prevalence of mental illness in spouses and partners of those with mental illness. This study will assess within- and cross-mental health disorder correlations in husband-and-wife pairs.
Methods:
A cross-sectional study design was employed using medical claims data from the Deseret Mutual Benefit Administrators (DMBA), linked to demographic information from employee eligibility files, 2020. Analyses involved 21,027 contract holders aged 18-64 (68.6% male, 31.4% female), with sub-analyses on 16,543 married individuals. Summary statistics, as well as rates, and rate ratios adjusted for age, sex, and dependent child status were calculated to describe the data.
Results:
The rate of stress is 19.2%, anxiety is 26.4%, and depression is 23.6% in spouses of contract holders with the same respective disorders. Rates of stress, anxiety, and depression in a spouse are greatest if the contract holder has schizophrenia. Rates of mental illness in wives of male contract holders experiencing mental health disorders tend to be greater than the rates of mental illness in husbands of female contract holders experiencing mental health disorders. Rates of stress, anxiety, and depression in spouses of contract holders tend to be 2-3 times greater when the contract holder has a mental health disorder, after adjusting for the contract holder's age, sex, dependent child status, and difference in age within husband-and-wife pairs. However, differences in the magnitude of observed associations vary. The rate of a spouse having stress is 5.5 times greater if the contract holder has schizophrenia (vs. does not have schizophrenia), whereas the rate of a spouse having stress is 1.4 times greater if the contract holder has sleep apnea (vs. does not have sleep apnea).
Conclusion:
Mental health disorders in spouses of contract holders are greater if the contract holder has a mental health disorder, more so when the contract holder has more serious mental illness. Both within- and cross-mental disorder correlations exist. These results have implications on relationship quality and the mental health of offspring.
