چکیده انگلیسی

Starting in adolescence and continuing through adulthood, women are twice as likely as men to experience depression. According to the response styles theory (RST), gender differences in depression result, in part, from women’s tendency to ruminate more than men. A meta-analysis was performed to evaluate gender differences in rumination in adults (k = 59; N = 14,321); additionally, an analysis of subtypes of rumination – brooding and reflection – was conducted (k = 23). Fixed effects analyses indicated that women scored higher than men in rumination (d = .24, p < .01, SEd = .02), brooding (d = .19, p < .01, SEd = .03) and reflection (d = .17, p < .01, SEd = .03); there was no evidence of heterogeneity or publication bias across studies for these effect sizes. Although statistically significant, the effect sizes for gender differences in rumination were small in magnitude. Results are discussed with respect to the RST and gender differences in depression.

مقدمه انگلیسی

Gender differences in rates of depression are well documented in the literature; beginning in adolescence, rates of depression in women are greater than in men, and by adulthood, women are twice as likely as men to become depressed (for a review, see Kessler, 2006). Numerous theories have been set forth to explain the gender differences in depression, citing psychological, sociocultural, and biological factors (for reviews, see Boughten and Street, 2007, Hankin and Abramson, 2001 and Hyde et al., 2008). A prominent psychological theory, the response styles theory (RST; Nolen-Hoeksema, 1987 and Nolen-Hoeksema, 1991), purports that women have a greater tendency to ruminate on their depressive symptoms and distress than do men, and this contributes to greater rates of depression in women. According to the RST, rumination involves repetitively and passively focusing on symptoms of distress and on the possible causes and consequences of these symptoms. Because rumination enhances the effects of depressed mood on thinking, impairs effective problem solving, interferes with instrumental behavior, and erodes social support, the initial symptoms of depression among people who chronically ruminate are likely to become more severe and evolve into episodes of major depression and rumination may prolong current depressive episodes (Nolen-Hoeksema, Wisco, & Lyubomirsky, 2008). The RST has spurred a large body of empirical research on the role of rumination in the onset and duration of depression (for reviews, see Nolen-Hoeksema, 2012 and Nolen-Hoeksema et al., 2008). Furthermore, the theoretical assumptions of the RST have been incorporated into broader models of depression risk (e.g., Hankin and Abramson, 2001 and Hyde et al., 2008). Although evidence for gender differences in rumination has emerged consistently in the literature, the magnitude of this difference has varied from study to study. In an effort to systematically review the rumination literature in children and adolescents, Rood and colleagues (2009) conducted a meta-analysis of gender differences in rumination in youth. Results of their analysis indicated that gender differences in rumination are quite small in children (d = .14) with girls significantly more likely to ruminate than boys. In adolescence, this gender difference was significant and larger in magnitude (d = .36). The authors reported that these results provide some evidence of the RST in youth and suggest that during adolescence, the increased magnitude of gender differences in rumination may parallel that seen in rates of depression. Another meta-analysis, conducted by Tamres and colleagues (2002), examined gender differences in coping mechanisms and included 10 studies reporting on gender differences in rumination. Results yielded a small but significant effect of gender on rumination (d = .19), with women more likely to ruminate than men. However, the Tamres analysis differs from the current study in several important ways. First, Tamres and colleagues focused on methods of coping (e.g., their search terms included “coping”, “stress management”) in response to a broad range of stressors, including relationship stress, physical pain, and health issues (e.g., cancer, artificial insemination). Thus, their analysis was based on a much broader definition of rumination (i.e., including thoughts about physical pain, academic performance, relationships) rather than specifically on depressive rumination as defined above. Secondly, their review included studies of children and adults and results were collapsed across these groups, thus obscuring potential influences of developmental stages on the gender differences in rumination ( Rood et al., 2009). In contrast, the current study focuses specifically on depressive rumination in adults so as to directly address the tenets of the RST. Despite the prominence of the RST in the field, no quantitative analysis of gender differences in depressive rumination has been conducted in the adult literature. The current review was conducted to provide a meta-analysis of the literature on gender differences in rumination in adult samples. We reviewed studies that included a measure of rumination, focusing on depressive rumination, which is most commonly measured by the Ruminative Responses Scale (RRS; Nolen-Hoeksema & Morrow, 1991) and the Rumination on Sadness Scale (RSS; Conway, Csank, Holm, & Blake, 2000), both of which are self-report measures. The RRS is a 22-item subscale from the Response Styles Questionnaire; participants rate how often they experience each response when they feel sad, blue, or depressed. Items focus on the meaning of rumination, on the subjective feelings related to depressed mood, on symptoms, and on consequences and causes of the mood (Luminet, 2004). Sample items on the RRS include, “Think, ‘What am I doing to deserve this?’” and “Go away by yourself and think about why you feel this way.” The RSS is a 13-item measure assessing how often participants experience each response in situations in which they feel sad, down, or blue. Items focus on the intensity and repetitive quality of ruminative thoughts, the difficulty with stopping ruminative thoughts, attempts at understanding the nature of one’s distress, and the lack of instrumental goal orientation ( Luminet, 2004). Sample items on the RSS include “I repeatedly analyze and keep thinking about the reasons for my sadness” and “I exhaust myself by thinking so much about myself and the reasons for my sadness.” A review of the psychometric properties of the RRS and RSS can be found in Luminet (2004). In addition to our analysis of global measures of depressive rumination, we examined gender differences in subtypes or components of rumination – brooding and reflection – obtained from a factor analysis of the RRS items that remained after eliminating items that could be argued to overlap with depressive symptoms (Treynor, Gonzalez, & Nolen-Hoeksema, 2003). This scale consists of five items assessing brooding, or passive, perseverative, maladaptive self-focused thought, and five items assessing reflection, a neutrally valenced, less maladaptive self-reflective strategy. Compared to reflection, brooding may be more strongly associated with depression severity, particularly over time, and some evidence suggests that gender differences in brooding may be greater than gender differences in reflection (e.g., Treynor et al., 2003). By estimating the overall effect size of gender differences in rumination, as well as the brooding and reflection components of rumination, we sought to provide the field with a quantitative analysis of past research and examine the basic tenets of the RST regarding gender differences in rumination in adults. Furthermore, the results of the current study may serve to guide future research efforts in elucidating the gender differences in rates of depression.
