ABSTRACT:

A quantitative approach descriptive study was conducted to assess marital satisfaction among 60 spouses of patients diagnosed with severe mental illness. The objectives of the study were to; assess the marital satisfaction among spouses of patients with severe mental illness, find the association between marital satisfaction of spouses and their selected demographic variables and find the association between marital satisfaction of spouses and selected patient variables. The data was collected using socio demographic sheet of both spouses and patients, Couples Satisfaction Index (structured interview). The major findings of the study were, the marital satisfaction among spouses of 60 patients with severe mental illness was assessed. Satisfaction in marital relationship was found in 41(68.3%) of the spouses and 19(31.7%) were unsatisfied in their marital relationship. It was found that among the 60 subjects, 48(80%) were unhappy with their relationships and only 12(20%) of the subjects were happy in their marital relationship. Also it was found that, only 5% of the subjects feels the relationship as interesting, 1.7% as good, 3.3% as full, 3.3% as full and friendly, 8.3% as sturdy and 5% as hopeful and enjoyable. These findings reveals that the spouses of mentally ill clients are themselves at risk for psychological distress due to the burdens associated with caring for someone with mental illness; burdens such as the feelings of helplessness, hopelessness, fear, uncertainty, the possibility of re-occurrence of disease, the emotional strain on the spouse, and the individual’s lack of energy.

INTRODUCTION:

Marriage is one of the most important events of life affecting social status as well as the psyche of an individual. It not only serves to satisfy the fundamental biological need of sexual gratification through a socially acceptable way but also helps the individual to achieve a higher level of personality maturation.1Marital satisfaction is a mental state that reflects the perceived benefits and costs of marriage to a particular person.2 Marital satisfaction not only makes people happier, healthier, and more joyful life but also contributes in the health of both partners , life durability and rearing the next generation.3 Moreover, a spouse may provide emotional intimacy and support, fulfilling an essential human need for connection.4

 

Mental and physical health problems of a spouse can be difficult and upsetting for both patient and partner.2There is a sizable body of literature showing an association between psychiatric illnesses and marital dissatisfaction.4 Research suggests that partners of mentally ill individuals are themselves at risk for psychological distress due to the burdens associated with caring for persons with mental illness; burdens such as the feelings of helplessness, hopelessness, the possibility of re-occurrence of illness, fear, uncertainty, the emotional strain on the spouse, the endless worrying, and the individual’s lack of energy.5

The data presented in Table 5. shows that calculated x2 values are more than the table value for age (χ2(1)= 5.398, p<0.05),gender (χ2(1)= 6.213, p<0.05), occupation (p<0.01), intercaste marriage (p<0.05) presence of illness(χ2(1)= 4.408, p<0.05) So there is statistically significant association between marital satisfaction and their and selected socio demographic variables such as age, gender, occupation, intercaste marriage an presence of any illness. No significant association was observed between marital satisfaction and other selected socio demographic variables.

 

The data presented in Table 6. shows that calculated χ2 values are more than table value for gender (χ2 ((1)= 6.213, p<0.05), diagnosis (χ2 (1)= 5.287, p<0.05) and months of illness in past 2years (χ2 (1)= 5.287, p<0.05) So there is a significant association between  subjects marital satisfaction and selected patient variables such as gender, diagnosis and months of illness in past 2 years. No significant association was found between marital satisfaction of spouses and other patient variables.

 

DISCUSSION:

In the present study, the marital satisfaction among spouses of 60 patients with severe mental illness was assessed. Satisfaction in marital relationship was found in 41(68.3%) of the spouses and 19(31.7%) were unsatisfied in their marital relationship. It was found that among the 60 subjects, 48(80%) were unhappy with their relationships and only 12(20%) of the subjects were happy in their marital relationship. Also it was found that, only 5% of the subjects feels the relationship as interesting, 1.7% as good, 3.3% as full, 3.3% as full and friendly, 8.3% as sturdy and 5% as hopeful and enjoyable. These findings reveals that the spouses of mentally ill clients are themselves at risk for psychological distress due to the burdens associated with caring for someone with mental illness; burdens such as the feelings of helplessness, hopelessness, fear, uncertainty, the possibility of re-occurrence of disease, the emotional strain on the spouse, and the individual’s lack of energy. This study was also supported by Whisman, M. A. (2007) in his study on Marital distress and DSM-IV psychiatric disorders in a population-based national survey, stated that there is a sizable body of literature showing an association between psychiatric illnesses and marital dissatisfaction.4  Matthias C.(2006) in his study on Quality of life of spouses of mentally ill also stated that, spouses of people with mental disorder experience various forms of objective and subjective burden. This should negatively affect their quality of life. Compared with the general population, the quality of life of the spouses of mentally ill people was lower in the domains ‘psychological well-being’ and ‘social relationships. There was a significant association between the patient's functional level and the spouse's quality of life.6

 

The current study shows that there is a statistically significant association between marital satisfaction of the spouses and their selected demographic variables such as age (χ2 (1)= 5.398, p<0.05),gender (χ2 (1)= 6.213, p<0.05), occupation (p<0.01), intercaste marriage (p<0.05) presence of any  illness(χ2 (1)= 4.408, p<0.05). It was found that the spouses above the age group of 45 experienced good marital satisfaction compared to the age group below 45 years. This may because that, the age group above 45 years may  have more marital adjustment, understanding, good coping skills etc. compared to the age group below 45 years. This was par with a study conducted by Robert W.(1997) in a study Long term marriage: age, gender and satisfaction, he stated that couples, some of who at are middle aged and on the threshold of old age, have the potential for providing emotional support and increasing affective positivity.7 Gender also plays a significant role in marital satisfaction. From the study it was found that spouses of female patients experienced more satisfaction in marital relationship than that of spouses of male patients. This may because, the female spouses may have fear, hopelessness, helplessness, dependent, uncertainty, poor coping skills compared to that of the male spouses. This was supported by a study by Sandhya C. has revealed that women experience and respond to stress in distinctive ways compared to men. Women's stress response process is both qualitatively and quantitatively different in terms of hormonal profile, activation of the sympathetic, adrenal, medullary and hypothalamic-pituitary-adrenal-cortical response pathways, and in emotional quality. In addition, the nature of women's lives and realities render them at risk for stress-related effects more often than men.8 Being unemployed, experiencing a drop in socio-economic level were associated with a poor marital outcome. The unemployed individuals lack sociological functions such as time structure, status and identity, social contacts and regular activity. They may be residing in home only, which in turn could develop many illnesses. Moreover they have financial constraints in meeting the medical cost. It was found that a significant association existed between type of marriage and marital satisfaction. Individuals with arranged marriage experienced more satisfaction than that of intercaste marriage. This may because in intercaste marriage the individuals may have less family support, poor coping skills etc. compared to that individuals with arranged marriage. Presence of illness in spouses also showed significant association between marital satisfaction. This was in par with a study conducted by Coyne J on Couples coping with chronic and catastrophic illness. It stated that the associations between different physical health problems of a spouse and the participant’s marital satisfaction were evaluated in a United States population-based survey of married individuals. It was found that compared to people whose spouse did not have the corresponding health problem, marital satisfaction was lower for people with a spouse suffering from various physical illness.9

 

In the study, it was also found out that there was a significant association between marital satisfaction and selected patient variables such as gender (χ2 (1)= 6.213, p<0.05), diagnosis(χ2 (1)= 5.287, p<0.05) and months of illness in past 2years ( (χ2(1)= 5.287, p<0.05).  Gender plays a important role in marital satisfaction. In the study it was found that marital satisfaction was high in female patients compared to that of male patients. This may because, the male spouses has more adjustment, good coping skills etc. than that of female spouses This was supported by a study by Sandhya C. has revealed that women experience and respond to stress in distinctive ways compared to men. Women's stress response process is both qualitatively and quantitatively different in terms of hormonal profile, activation of the sympathetic, adrenal, medullary and hypothalamic-pituitary-adrenal-cortical response pathways, and in emotional quality. In addition, the nature of women's lives and realities render them at risk for stress-related effects more often than men.8. In this study it was found that, diagnosis of the patient has an effect on marital relationship. This study was par with a study conducted by Coyne et al. stated that a significantly high association was also found between a spouses diagnosed with mood disorders and the participant’s decreased marital satisfaction. One possible reason for this finding is that living with a spouse diagnosed with mood disorder is a source of considerable psychological burden. Living with a depressed spouse may also affect a person’s mood making it difficult to function well in the relationship5. A study conducted by  Shahrokh A et.al (2012 )also stated that mood disorders such as depression has a direct influence on lowering marital satisfaction.10 It was also fund in the study that months of illness also have a significant association with marital satisfaction. In study it revealed that, patients with months of illness less than 6 months experienced more marital satisfaction than that of patients with more than 6 months. This may because due to the duration of illness, increased relapse rates, non-compliance to treatment etc.

 

CONCLUSION:

Marital satisfaction is a special case of relationship satisfaction, and is the degree to which partners in marriages assess their approval of different aspects of their marital relations. Mental and physical health problems of a spouse can be difficult and upsetting for both patient and partner. As a couple learns to cope with the consequences of illness, the relationship changes and the sick individual is likely to turn to his or her spouse for emotional and tangible support.
