Depression, though generally episodic, results in lasting disability, distress, and burden. Rising prevalence of depression and suicide in the context of epidemiological transition demands more attention to social dimensions like gender related stresses, dysfunction, and their role in outcome of depression. Cross-sectional and follow-up assessment of men and women with depression at a psychiatric tertiary centre was undertaken to compare their illness characteristics including suicidal ideation, stresses, and functioning on GAF, SOFAS, and GARF scales ( = 107). We reassessed the patients on HDRS-17 afer 6 weeks of treatment. Paired t-test and chi-square test of signifcance were used to compare the two groups, both before and afer treatment. Interpersonal and marital stresses were reported more commonly by women ( < 0.001) and fnancial stresses by men ( < 0.001) though relational functioning was equally impaired in both. Women had sufered stresses for signifcantly longer duration ( = 0.0038). Men had more impairment in social and occupational functioning compared to females ( = 0.0062). History of suicide attempts was signifcantly associated with more severe depression and lower levels of functioning in case of females with untreated depression. Signifcant cross-gender diferences in stresses, their duration, and types of dysfunction mandate focusing on these aspects over and above the criterion-based diagnosis. 1. Introduction Major depressive disorder (MDD) is a common and treatable psychiatric disorder with high morbidity and mortality. Complex interplay between mind, body, society, and cul- ture has been implicated in the incompletely understood pathophysiology of depression [1]. Antecedent stresses and resulting disabilities interact with each other to worsen the depression, whichinitself becomes additional stress. Patients reports of stresses and adjustment problems frequently do not get due importance in understanding and managing depression, which may explain partial or delayed treatment response and frequent relapses. Very few diferences in the course of depression have been detected across gender. Factors like time taken for recovery, time for frst occurrence, and number and severity of recurrences did not difer [2]. Background social contexts and support systems are important for understanding the contributing determinants of disease and for planning of treatment [3]. Depression has been identifed as signifcant cause of morbidity and mortality [4]. Ferreira et al. (2013) [5] showed how rural India may be topping the list for depression and disability following organic disorders like stroke. Bromet et al. (2011) [6] in their exhaustive and impressive survey of cross- national epidemiology of depression showed how social conditions distinguish prevalence, disability, and burden of depression across ranges of income. Seedat et al. (2009) [7] showed the temporal narrowing of gender role traditionality in case of MDD among cohorts across the globe, which explains changing trends observed in Indian clinical practice and popular newspapers. Epidemiological transition [8, 9], globalization, and rapid urbanization [10] have contributed to changing social and family structure and function.

However, generally family is a source of immense social support as well as of stress in Indian culture. Stresses experienced by males and females difer in nature and perception. Stress is known to precipitate or exacerbate episodes of depression. Mitigating stress by efective stress management has proved to be efective inpreventionof MDD [11]. Te nature of these stresses needs scrupulous assessment if preventive strategies have to be devised. 2. Subjects and Methods Tis is a hospital-based study conducted at a tertiary hospital of a medical college. Tis hospital caters free medical ser- vices for the community. Patients predominantly from lower socioeconomic strata fromin and around city, as well as from out-station, beneft from this hospital. A signifcant minority also comes from higher middle income social circles of the hospital staf. Outpatients in psychiatry department clinically diag- nosed to have depression were screened for inclusion in this study. Data collection was completed in a period of twelve months fromJanuary 2011 onwards. Te study was completed over a period of two years. Prior permission of ethics committee of the institute was obtained and informed written consent taken from each patient. Consecutive patients with depression (current major depressive episode, with or without dysthymic dis- order and/or major depressive disorder) without signifcant biomedical illness were informed about the study and those willing to participate were included. A total of 107 such patients, 66 females and 41 males, were interviewed by authors (Sharmishtha S. Deshpande, Poonam N. Patil, and Bhalchandra Kalmegh) in the stipulated period of time. Find- ings about clinical characteristics of depression, presence of atypical features and comorbid psychiatric disorders in major depression fromthis study have been reported elsewhere [12]. Tis paper focuses on the gender diferences in these patients stresses and in functioning in various spheres. Afer initial screening, SCID-I (Structured Clinical Inter- view for DSM IV axis I disorders) was administered to confrmthe diagnosis of MDD[13]. HDRS (17 itemHamilton Depression Rating Scale) [14] was administered to note the severity of depression. Te patients were asked if they were undergoing any kind of stress in their life that may or may not be responsible for their depressed mood. Stresses reported by these patients were recorded verbatim(with duration) as perceived by these patients, which were later classifed as per SCID-I axis IV guidelines and analyzed. Teir suicidal ideation was recorded using Paykels scale [15]. Te patient was then asked about any attempt of self- harm along with its details in the past. Any accidental poisoning or injury was also probed to rule out possibility of suicide attempt. Te patients were asked to follow up at 3 and 6 weeks for review. Attrition was signifcant and the patients ofen returned afer symptom exacerbation following drug dropout. Te number of patients taking regular treatment for six weeks or more ( = 40) was included in the second part of study. HDRS (17 item Hamilton Depression Rating Scale) was administered and level of functioning was also assessed in these patients. Level of functioning was assessed and recorded with the help of GAF (Global Assessment of Functioning) scale, SOFAS (Social and Occupational Functioning Assessment Scale), and GARF (Global Assessment of Relational Func- tioning) scale. Tese are the scales for assessment and rating of axis V in DSM IV [16]. A semistructured questionnaire to score on SOFAS and GARF has been prepared by the author (Sharmishtha S. Deshpande) and used in an earlier study [17]. Interrater reliability of these scores has been reported in literature [18] and was also confrmed by the investigators in this study. Data obtained was entered in Microsof Excel sheets and later imported in suitable format for analysis. Bio- Medical Data Processor (BMDP 2.0) was used for statistical analysis. Data were analyzed for gender-wise comparison of various illness characteristics, namely, severity, stresses, suicidal ideation and functioning using -test and chi-square tests of signifcance. 3. Results Tis study assessed 107 patients with depression who were newly diagnosed to have depression or old patients who were of treatment for at least a month and had developed recurrence of symptoms. In addition, forty patients who had received regular treatment with antidepressants for six weeks or more were also reviewed for improvement in depressive symptoms and functioning. Initial sample included 66 females and 41 males rep- resenting all age groups though mean age for females was higher than for males (Table 1). More males were single than females, whereas illiteracy and rural background in females were much higher compared to males. Patients coming from urban, semiurban, and rural areas were well represented in the sample. Majority of patients were servants or lower class workers and 40.9%women were homemakers, though we see representation of all types of occupations. In Table 2 we see the improvement in mean HDRS score from 21 to 11.5. Mean HDRS score was comparable among males and females before as well as afer treatment (Table 2). Mean duration of ongoing stress reported was much higher in women though duration of illness revealed from the history was comparable. Te numbers of men and women with past history of suicide attempt as well as extent of suicidal ideation as measured by Paykels score were comparable. However, mean duration of sufered stress was signif- cantly higher in females. Tis is the duration of prominent stress as reported by the patient during clinical interview ( = 0.0038). However, the nature of stresses perceived was signifcantly diferent as mentioned in Table 3. Women in this study had frequent problems with primary support group than men (Table 3). Relationship problems in the family, especially with husband, were commoner Depression Research and Treatment 3 Table 1: Sociodemographic characteristics of the 107 patients with MDD.

Conficts with in-laws and children were also reported by many women. Males reported fnancial problems as the commonest stress. Tis was not seen in case of women ( < 0.001). Problems related to social environment and occupational problems, though not statistically signifcant, were more among men. Also, other stresses and no stresses were reported more by men. Other stresses reported were academic failure, death of close relative, failure in romantic relationship, social isolation, and so forth. When we considered the married subgroup of the sample, 5 out of 22 men and 39 out of 53 women had reported problems with primary support group ( 2 = 14.5518, = 0.00013). Table 3 also refects on high number of women (31 out of 53 married women) and few men (4 out of 22 married men) reporting problems with spouse as the source of stress ( 2 = 8.5942, = 0.00337). Te diference in the number of married men (13/22) and women (13/53) reporting economic problems was also statistically signifcant ( 2 = 6.7448, = 0.0094). Afer 6 weeks of treatment, 38.4% women and 42.8% men patients were in remission (HDRS-17 score < 7). Among women with persistent depression, 43.7% reported interpersonal problems with spouse as predominant stressor and additional 31.2% variety of problems with other family members. Among women in remission, 70% had reported stress due to problems with children or daughters-in-law. Other sources of stress reported were own physical illness or fnancial problems, proportionately much less in either group. Half of the males in remission had not reported any stress, whereas the other half had stress due to separation from various family members. Among men with persistent depressive features, no stress was reported by 25%, fnan- cial stress by 37.5%, and some familial stress like dispute with brother, infertility, and separation from parents by the remaining 37.5%. We have assessed social, occupational, and relational functioning of these patients in detail. Functioning of an indi- vidual in the sphere of household relationships is very impor- tant but seldom assessed systematically. Global Assessment of Relational Functioning scale (GARF) addresses issues like problem solving, organization, and emotional climate in the family which refect on the quality of relationships. Te functioning as a family rated from daily routines, warmth, and conficts is rated in the range from optimal functioning to dysfunctionality, which are to be rated by psychiatrist in 1000 scale. Te scale has been used for a study in Brazil on validity of GARF; cut of of 70 was found to have acceptable validity coefcients [18]. Relational functioning (GARF score) was maximally afected functioning in this disorder, equally in males and females. It remained so even afer treatment (score < 70) especially in case of females. Social and occupational func- tioning was more impaired in men than women at the time of presentation to psychiatrist. We see that 28 (42.4%) of women in this sample were housewives; many were working as maid, farmer, labourer, and so forth. Tey seem to have continued to do their work despite distress caused by illness. Global and mainly social and occupational functioning is afected signifcantly to a greater extent in males. When we compared GAF and GARF scores before and afer 6 weeks of treatment by paired -test, improvement was signifcant ( < 0.001) in males as well as females, which refects on comparable response to treatment in terms of improvement in functioning in these spheres across gender. However, improvement in social and occupational functioning score (SOFAS) before and afer treatment was signifcant in females ( < 0.001) but not signifcant in males ( = 0.120). Women but not men with past history of self-harm had worse HDRS scores as well as worse functioning in all the spheres. Tis indicates further suicide risk in these patients and explains more frequency of suicide attempts among females. Te time interval between suicide attempt and interview was variable from 1 month up to 10 years. However, it was comparable in males and females. Some patients also had history of more than one attempt. Afer treatment scores for females show signifcantly higher HDRS score with past suicide attempt (16.85 +/ 8.21) than those without past history of suicide attempt (8.94 +/ 6.01). But the functioning scores were comparable to those without history of suicide attempt in females as well as males. 4. Discussion In routine psychiatry practice, we see depressed men and women with varied stresses and diferential impact of illness on their functioning. Tere seems to be intimate and complex 4 Depression Research and Treatment Table 2: Comparison of duration of stress and illness characteristics across gender.

Tis study attempted to objectively assess this relationship. In the last three decades suicide rate has increased by 43% in India and ratio of males to females is stable at 1.4 : 1 [19]. Major depressionis the commonest among contributors. Importance of social and public health aspects of suicide prevention in India has been emphasized in literature [20, 21]. Gender diferences in suicide attempters are succinctly reported in a study fromSouth India [22]. Females were more illiterate, rural and had less psychopathology. Signifcant numbers of females in our study were also from rural background and illiterate, but they reported sufering from stresses for signifcantly longer time (Table 1). Tis sample had patients with varied educational level and occupations represented, which can be seen as a limitation of this study. Comparable illness characteristics in males and females have been confrmed (Table 2) as reported in previous studies [2, 2325]. However, females readily afrmed stresses, especially in the family domain (Table 3). Duration of these stresses was signifcantly prolonged in females as seen in Table 2. Tis could be due to more sensitivity of women towards problems in relationships as well as a function of dual importance of home in their lifeas a work place and as an intimate group. Social factors indepressionhave beenextensively studied. Social variables are reported to difer across gender though there is no diference in overall course or severity of depres- sion [2, 2325]. Tis has been confrmed in the present study. Long term follow-up studies in women have reported persistent efect of depression on their social interactions and relationships [25]. We see modest degree of improvement in mean scores of social-occupational, relational, and global functioning afer treatment of depression (Table 4). Tis study assessed functioning using DSM-IV axis V scales. SOFAS and GARF are diferent constructs but related to GAF [14]. GARF has been correlated with clinician-assessed axis II pathology [26]. Tese scales are useful in assessing changes in personality psychopathology, social adjustments, and relationship skills. All these are important in prognosis and outcome of major depressive disorder. Gender diferences in stress experiences and stress vul- nerability have been elaborately discussed by Eisenberg [1], in which fndings mainly indicate protective efect of marriage against depression in males, but more negative efect on females. In animal research the opposite efect of same stress on male and female hippocampus has been documented indicating probable biological aspect of these fndings [27]. Recent large systematic study Predict D has reported that preventive measures will achieve a greater reduction in the prevalence of depression than measures undertaken to eliminate risk factors afer onset [7]. Our study has highlighted perceived stresses of local Indianpopulations and their diferential impact across genders and marital status. In an Indian study, signifcantly more women with features of neurasthenia spectrum disorder had identifed marital problem as the most important perceived cause for their sufering, while none of the men did so [28]. Similar results from this study can be explained as patients are from the similar cultural background (Table 3). Tough depression is the third leading cause of disability, it is seldomquantifed. We measured it clinically (HDRS) and also indirectly interms of functional impairment (Table 4). In a 10-year follow-up study of depression, impairment in social functioning (housework, social interactions, and leisure) was known to persist for years afer recovery though work functioning improved signifcantly [29]. Functional disability in females, especially housewives, is seldom noticed till it Depression Research and Treatment 5 Table 3: Various stresses reported by male and female patients with MDD categorized as per axis IV from SCID I.

Tough they sufer great distress, they continue to do household work and try their best to conform to role expectations embodied by social norms. Concern about conforming to social expectations in females is also reported in other studies [30]. Difculties in social and relational functioning are likely to lead to secondary distress inwomenwhichcouldbe the perpetuating factors for depression and suicidality. Inour study 24 (60%) patients hadfailedto achieve remis- sion afer treatment (HDRS scores > 7).

Tis may explain the observation that risk of self-harm persists afer apparent clinical improvement. As the concept of quality of life ofen difers across various sociocultural groups, assessing their functioning in various spheres seems to be more pertinent. Also, it is hard to fnd indigenously validated quality of life scales for depression suitable across heterogeneous patient groups in diverse Indian culture. Most Indian women are also known to equate their quality of life with their perceived adequacy in rolefunctioning [19]. In an Indian study, the most common reasons for suicidal attempts were marital and interpersonal problems followed by psychiatric and physical illnesses in females [21]. 71% of suicide attempters in India are below the age of 44 years [21]. Assessment of relational functioning is thus crucial in MDD patients. We see that this was the most afected sphere of functioning and least to improve with routine outpatient treatment for depression (Table 4). Tough very few males reported stresses in the primary support group (Table 3), their GARF score is comparable with females as depicted in this table. Tis could also be due to underreporting of relational stresses by men. Te relational functioning is likely to have worsened due to depressed or irritable mood and resultant depressive cognitions. It needs to be explored fur- ther by undertaking a longitudinal study to see if enhancing relational functioning helps in improving depressive features in either gender. Severity of depression and dysfunction in women with history of suicide attempts are higher as depicted in our study (Table 5) highlighting that establishing diagnosis on axis I is not equivalent to full description of psychopathology. Role of axis IV (stresses) and V (functioning) in perpetuating axis I disorder needs to be understood individually in every patient with depression. Limited success in managing depression with sole phar- macotherapy has beenmentionedinliterature [31] andso also more favourable outcome with combined use of psychother- apy with pharmacotherapy [32]. Review of contextual inter- ventions for MDD has revealed signifcant success in 8 out of dysfunction afects social interactions, relationships, and work functioning in a negative way persistent and becomes pervasive Added to biological MDD or dysthymic Males: more of social, fnancial stresses Females: relationship problems, failures, and losses Axis V: resultant diathesis and axis II Distress worsening of mood remains disorder-axis I Axis IV: stresses Figure 1: Interactive model of axes I, IV, and V in depression. 13 studies reviewed recently [33]. Te interpersonal problems especially in depressed patients living with a partner have been reported to be successfully managed by group couples therapy, with lesser number of dropouts in the London Depression Intervention Trial [34]. Such management needs to be a part of regular treatment of depression in Indian setting. Considering interactions between axes I, IV, and V for appropriate psychosocial intervention along with drug treatment is necessary for comprehensive use of biopsychoso- cial model in diagnosis and management. Figure 1 shows the interaaactive model of axes I, IV, and V in depression. Limitations of the Study. Patients across wide age range, educational levels, diferent occupations, and marital status are included in the sample reducing its homogeneity. Depression Research and Treatment 7 Limited duration of followup (6 weeks) and small size of afer treatment group of patients ( = 40) limit generaliza- tion of fndings. 5. Conclusion Tere are qualitative and quantitative diferences in stresses experienced by males and females that may have both cause and efect relationship with depression via resultant dysfunc- tion. One should consider causative role of functioning in the complex etiopathology of depression in the context of body, mind, society, and culture. Gender diferences in stresses and various spheres of functioning should be addressed in routine clinical practice. Relational functioning, being the most afected domain, should be assessed regularly in depressed patients. Women have ofen sufered chronic stress commonly due to problems with primary support group. Mental health professionals should attend to these problems for neces- sary intervention. More proactive approach by clinicians to enhance social and relational functioning appears important in suicide prevention. Distinct diferences across gender in stresses and func- tioning in depression warrant longitudinal studies to explain the directionality between functioning, stress, and depres- sion.
