Vulnerability to depressive mood reactions: Toward a more powerful test of the diathesis–stress and causal mediation components of the reformulated theory of depression.

To provide a more powerful test of the diathesis–stress component of the reformulated theory of depression (Abramson, Seligman, & Teasdale, 1978), we extended and refined the Metalsky, Abramson, Seligman, Semmel, and Peterson (1982) study and examined whether the content of college students' attributional styles (hypothesized attributional diathesis) as measured at Time 1 interacted with the outcomes students received on a class midterm exam to predict their subsequent depressive mood responses. In addition, to test the mediation component of the theory, we examined whether the relation between the hypothesized attributional diathesis and failure students' subsequent depressive mood responses to their low midterm grades was mediated by the particular causal attributions these students made for their low grades. The results partially corroborated the current statement (Abramson, Alloy, & Metalsky, 1986; Abramson, Metalsky, & Alloy, 1986a, 1986b) of the diathesis–stress component of the theory. Whereas students' immediate depressive mood reactions were predicted solely by the outcomes they received on the class midterm exam, their enduring depressive mood reactions were predicted solely by the hypothesized Attributional Diathesis?×?Outcome on Midterm Exam interaction. The direction and form of the interaction were in line with prediction. The results corroborated predictions derived from the mediation component of the theory as they applied to students' enduring mood responses.

Cognitive styles and life events interact to predict bipolar and unipolar symptomatology.

This study examined the interaction of cognitive style (as assessed self-report and information-processing battery) and stressful life events in predicting the clinician-rated depressive and manic symptomatology of participants with Research Diagnostic Criteria lifetime diagnoses of bipolar disorder (n?=?49), unipolar depression (n?=?97), or no lifetime diagnosis (n?=?23). Bipolar and unipolar participants' attributional styles, dysfunctional attitudes, and negative self-referent information processing as assessed at Time 1 interacted significantly with the number of negative life events that occurred between Times 1 and 2 to predict increases in depressive symptoms from Time 1 to Time 2. Within the bipolar group, participants' Time 1 attributional styles and dysfunctional attitudes interacted significantly, and their self-referent information processing interacted marginally, with intervening life events to predict increases in manic symptoms from Time 1 to Time 2. These findings provide support for the applicability of cognitive vulnerability–stress theories of depression to bipolar spectrum disorders.

Effects of daily events on mood states in major depressive disorder.

Major depressive disorder (MDD) is characterized by high negative affect (NA) and low positive affect (PA), but little is known about emotional reactivity in daily life. The authors used experience sampling methodology to investigate changes in NA and PA following minor daily events in MDD compared with healthy participants. Contrary to expectation, MDD participants did not report more frequent negative events, although they did report fewer positive events. Multilevel regression showed that both NA and PA responses to negative events were blunted in the MDD group, whereas responses to positive events were enhanced. NA responses to negative events persisted longer in MDD participants. Depressed participants with a positive family history or longer current episodes showed relatively greater NA responses to negative events.

Mood and the mundane: Relations between daily life events and self-reported mood.

Daily mood ratings and corresponding diary entries were studied to determine relations between common events and two independent mood factors—Positive Affect (PA) and Negative Affect (NA)—in a sample of 18 young adults over a 3-month period. In an extension of findings from earlier interindividual studies, PA (enthusiastic, delighted vs. sluggish, drowsy) was found to be associated with a wide range of daily events, whereas fewer correlations were found between these events and NA (distressed, nervous, angry vs. calm, relaxed). The relation between high PA and reported social interactions (particularly physically active social events) was especially robust, and its effects were noted repeatedly; NA was unrelated to social activity. As hypothesized, high NA was associated with physical problems; contrary to expectations, low PA also tended to be correlated with health complaints. Overall, the results reaffirm the importance of assessing NA and PA independently and suggest that PA is an interesting and important dimension that deserves more research attention. Theoretical considerations and clinical implications are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Attributional style and depressive symptoms among children.

The reformulation of helplessness theory proposes that an insidious attributional style accompanies and predisposes depressive symptoms. The present study investigated predictions of the reformulation among 96 8–13 yr olds who completed the Children's Attributional Style Questionnaire (ASQ) and Children's Depression Inventory twice, 6 mo apart. 83 of their parents completed the adult ASQ and the Beck Depression Inventory at their children's 2nd testing. Children who attributed bad events to internal, stable, and global causes were more likely to report depressive symptoms than were children who attributed these events to external, unstable, and specific causes. This depressive attributional style predicted depressive symptoms 6 mo later, suggesting that it may be a risk factor for depression. Children's attributional style for bad events and their depressive symptoms converged with those of their mothers but not their fathers.

Vulnerability to specific life events and prediction of course of disorder in unipolar depressed patients.

Tested a cognitive-life stress integrative model that predicted depressive symptoms following stressful life events when the negative events were personally meaningful to the individual, and likely to be interpreted as depletions or failure in the domain of central relevance to self-worth. 27 unipolar depressed outpatients completed a sociotropy-autonomy scale and were followed prospectively for periods of up to 2 yrs, with periodic assessments of life events and symptoms. As predicted, Ss' periods of worst symptoms followed a 3-mo period in which life event stress that matched their personally relevant domain significantly exceeded that of the nonrelevant domain. For Ss who experienced an onset following a symptom-free period, the severity of symptoms was significantly predicted by the interaction of their autonomy score and achievement events; however, the same pattern did not occur for sociotropy score and interpersonal events.

Trajectories of stressful life events and depressive symptoms during adolescence.

This 4-yr longitudinal study of 191 girls and 185 boys living in intact families in the rural Midwest examines the trajectories of life events and depressive symptoms in adolescence. The trajectories of depressive symptoms differ between boys and girls. Compared with boys, girls experienced a greater number of depressive symptoms after age 13. Changes in uncontrollable events are associated with the increases in girls' but not boys' depressive symptoms. Latent growth curve analyses show that, over 4 yrs, (1) depressive symptoms for girls changed according to a curvilinear pattern that is associated with changes in stressful events; (2) the level of depressive symptoms is related to the level of life events for both boys and girls; and (3) change in depressive symptoms is significantly related to change in stressful events only for girls. Girls living with less supportive mothers are more vulnerable to negative life changes. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Stressful life events and personality styles: relation to impairment and treatment outcome in patients with social phobia

Forty-five patients with social phobia and 15 individuals with no mental disorder were compared on number and type of life events experienced. Social phobia patients were further examined to evaluate the effect of negative life events and of the interaction between personality style and life events on severity of impairment and reactions to cognitive-behavioral group therapy. Patients with social phobia reported more negative life events than participants with no mental disorder. Among patients with social phobia, more frequent negative life events were associated with higher scores on measures of depression and general anxiety. Patients high on autonomy who reported more negative autonomous (i.e., achievement-oriented) life events also scored higher on measures of social anxiety and general anxiety. There were no significant interactions between sociotropy and the frequency of reported socially oriented negative life events. However, patients high on sociotropy scored higher on measures of social anxiety, depression, and general anxiety. Patients who had experienced more negative life events improved more after treatment on measures of social anxiety than did those who had experienced fewer negative life events. Implications of these findings and recommendations for future research are discussed.     

Gender differences in life events prior to onset of major depressive disorder: The moderating effect of age.

Theoretical models attempting to explain why approximately twice as many women as men suffer from depression often involve the role of stressful life events. However, detailed empirical evidence regarding gender differences in rates of life events that precede onset of depression is lacking, due in part to the common use of checklist assessments of stress that have been shown to possess poor validity. The present study reports on a combined sample of 375 individuals drawn from 4 studies in which all participants were diagnosed with major depressive disorder and assessed with the Life Events and Difficulties Schedule (Bifulco et al., 1989), a state-of-the-art contextual interview and life stress rating system. Women reported significantly more severe and nonsevere, independent and dependent, and other-focused and subject-focused life events prior to onset of depression than did men. Further, these relations were significantly moderated by age, such that gender differences in rates of most types of events were found primarily in young adulthood. These results are discussed in term of their implications for understanding the etiological role of stressful life events in depression.

Dimensional analysis of the Attributional Style Questionnaire: Attributions or outcomes and events.

Argues that the Attributional Style Questionnaire (ASQ) does not measure 3 attributional dimensions (i.e., internality, globality, and stability) but 2 outcome factors and several events factors. Two published subscale correlation matrices by C. Peterson et al (see record 1983-02470-001) and by A. J. Zautra et al (see record 1986-11854-001) were factor analyzed. In addition, ASQ data from 537 high school and college students were collected. A 3rd subscale matrix and 3 item correlation matrices were derived from these data and the factor analyses. All factor matrices were compared to hypothesized matrices, and the argument was supported. There may be little cross-situational consistency in attributional style.

Social support, life events, and depressive symptoms: A 1-year prospective study.

Examined associations between life events, social support, and depressive symptoms in a sample of 709 married women. Ss were administered the SCL-90, a life events scale, a social support scale, and a marital conflict scale in 1981 and again 1 yr later. For a sample of 473 Ss who initially were relatively asymptomatic and reported nonconflicted marital relationships, life events and social support were significant prospective predictors of depressive symptomatology (assessed 1 yr later). In contrast, identical analyses performed on the full, unselected sample yielded discrepant, likely misleading, results. The implications of these findings for the longitudinal study of dynamically interactive processes are discussed. (32 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Dependency and self-criticism: Vulnerability factors for depressive affective states.

A variety of theories have explained inappropriate negative affective states in terms of the activation of cognitive-affective structures by stressful events. To have predictive value, such theories need to specify the conditions under which activation will occur. The principle of specificity states that the degree of congruence between an event and a structure determines the probability of the structure's being activated. Counterposed to this principle is the principle of nonspecificity, based on the notion of the assimilation of diverse events by highly accessible structures. To test the relative importance of specificity and nonspecificity, dependent (n?=?16), self-critical (n?=?14), and control (n?=?15) female college students were selected using the Depressive Experiences Questionnaire. They listened to audiotaped portrayals of rejection by a boyfriend and of failure to be accepted into graduate school. The dependent variables were measures of anaclitic (dependent) and introjective (self-critical) state depression. Dependent subjects' anaclitic depressions were specific to rejection (specificity), but self-critical subjects reported introjective depression in response to both failure and rejection (nonspecificity). Surprisingly, dependent subjects also reported high levels of introjective depression. Application of the theoretical framework to clinical depression and to other negative affective states is suggested. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Response styles and the duration of episodes of depressed mood.

Examined the relationship between ruminative and distracting styles of responding to depressed mood and the duration of mood. 79 Ss kept accounts of their moods and responses to their moods for 30 consecutive days. The majority of Ss (83%) showed consistent styles of responding to depressed mood. Regression analyses suggested that the more ruminative responses Ss engaged in, the longer their periods of depressed mood, even after taking into account the initial severity of the mood. In addition, women were more likely than men to have a ruminative response style and on some measures to have more severe and long-lasting periods of depression.

Diurnal mood variation in major depressive disorder.

Depression disturbs mood, but a clear picture of diurnal mood rhythms in depression has yet to emerge. This study examined variations in positive affect (PA) and negative affect (NA), two dimensions of mood that generate diurnal patterns among healthy individuals. Repeated measurements of NA and PA in daily life were obtained over 6 days from 47 depressed outpatients and 39 healthy individuals using the Experience Sampling Method. Relative to healthy individuals, depressed individuals exhibited increasing PA levels during the day with a later acrophase. In contrast, depressed persons' NA exhibited a more pronounced diurnal rhythm and was more variable from moment to moment than healthy individuals'. Ambulatory mood measurements in depression suggest distinct diurnal disturbances of positive and negative affect. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Relation between depressive symptoms and stressful life events in a sample of disadvantaged mothers.

The bidirectional relation between life events and self-reported depression was examined across a 1-year period. With Time 1 depression controlled, Time 2 stress accounted for an additional 10% of Time 2 depressive symptoms. Health-related stress, family violence, and financial stress at Time 2 predicted Time 2 depression after control for Time 1 depression. With Time 1 stress controlled, Time 2 depression accounted for 8% of the variance in Time 2 stress. Time 2 depression predicted Time 2 health-related stress, financial stress, household changes, spouse–partner stress, family violence stress, and substance abuse stress, controlling for each of these stressors at Time 1. The results describe a complex relation between stress and depression and suggest that the relation between stress and depression is moderated by the type of stress.

Effects of induced mood on self-reported life events and perceived and received social support.

Tested the relation between mood (depressed [D], elated [E], or neutral [N]), induced by the Velten (1968) procedure, and college students' responses on a subjectively scored life events questionnaire and measures of perceived and received social support. A manipulation check showed that the mood manipulation was successful. There was a significant mood effect on the number of self-reported negative life events, with E Ss reporting the fewest. However, mood had no significant effect on the number of self-reported positive life events or the rated intensity of negative and positive events. Mood had a significant effect on perceived social support, with D Ss scoring the lowest. Self-report of received social support, however, was not affected by the mood manipulation. The findings challenge the widespread use of life event and perceived social support questionnaires whose independence from a mood-related response bias has not been adequately demonstrated.

Observations on relating teaching goals to student response styles and classroom methods.

Contends that instructor perceptions of student ability differences are partly influenced by class design favoring instructor rather than student needs. Analysis of different approaches to teaching undergraduate psychology courses indicates that instructor need-oriented classes encouraged avoidant, competitive, and dependent response styles. Dominant causes were: (a) uncertainty in and disenchantment with class activities, (b) competitive rewards and collaborative sanctions, (c) authority fixations, and (d) few transfer activities. Teaching goals attempting to attentuate these styles featured a classroom model with small group projects, class and small group student "teachers of the day," and instructor content study guides. Questionnaire and response style assessment data reveal that students exposed to this design liked the method, and reported their behaviors as more participatory, collaborative, and independent than those taught by traditional methods.

Sex differences in coping styles and implications for depressed mood.

Based on a sample of young adults in Miami-Dade County, Florida, this paper examined the extent to which there were sex differences in 3 coping style types: problem focused, emotion focused, and avoidance focused (Endler & Parker, 1990). Further examined were the extent to which sex differences in coping styles could be explained by sex differences in chronic strain; the extent to which sex differences in depressed mood could be explained by sex differences in coping style; and whether the effects of different coping style types on depressed mood varied by sex. Results suggested somewhat complex relationships among sex, coping, chronic strain, and depression. No sex differences in the use of problem-focused coping were observed when statistical controls for socioeconomic status were applied; however, women more often used avoidance-focused techniques. Although female respondents more often used emotion-oriented strategies compared to male respondents, such use did not prove to be fundamentally harmful for women. In fact, the effects of using emotion-focused strategies, such as the expression of feelings, reduced depressed mood for women, but not for men. Implications for practice and policy are discussed.

Differential responses to male and female depressive reactions.

Suggests that the commonly reported preponderance of female over male depression in incidence and prevalence studies requires further analysis. One explanation is that the social consequences of expression of depressive symptomatology are different for males and females. A comparison of 157 male and 189 female undergraduates' reactions to male and female case histories of common reactions to stress confirmed the hypothesis. Depression elicited more rejection of males than of females, and the sex difference in rejection of depression was more pronounced than for anxiety or flat affect-detached responses. A discriminant analysis suggested that depressed males are especially likely to be perceived as impaired in role functioning as compared with depressed females. Results suggest that depressed males are not rejected for expression of emotionality as such. Speculations about the causes and consequences of differential rejection of depression are noted.
