Impairment in the achievement domain in bipolar spectrum disorders: role of behavioral approach system hypersensitivity and impulsivity

AIM

Research indicates that bipolar disorder is characterized by both high levels of impairment and high levels of achievement. A critical, and yet largely unexamined question, is: what psychological mechanisms promote high accomplishment (and low impairment) among bipolar spectrum individuals? The aim of this study was to examine this question. The Authors also conceptually explore how the answer to this question can enhance the development of intervention and prevention strategies for adolescents with a bipolar spectrum condition.

METHODS

Academic transcript data were obtained for 120 college students who had either a bipolar spectrum disorder (N=54) or no major psychopathology (N=66).

RESULTS

Bipolar spectrum individuals obtained a lower cumulative grade point average (GPA, t=-2.9, P=0.005) and dropped more classes (t=2.1, P=or<0.04) than normal controls. The findings also have relevance to the behavioral approach system (BAS) dysregulation theory of bipolar disorder, as well as research on impulsivity among bipolar individuals. Specifically, follow-up analyses revealed that bipolar individuals exhibiting a combination of high BAS drive and low impulsivity earned higher GPAs than the remaining bipolar individuals. Thus, high BAS sensitivity, when paired with low impulsivity, may not be impairing and may contribute to the high achievement sometimes observed among bipolar individuals.

CONCLUSION

Such information is important for the development of prevention and intervention programs designed adolescents that lower risk for bipolar impairment without decreasing achievement.

Predicting bulimic symptoms: an interactive model of self-efficacy, perfectionism, and perceived weight status

An interactive model of perfectionism, perceived weight status, and self-efficacy was tested on 406 women to predict the bulimic symptoms of binge eating and inappropriate compensatory behaviors separately. This longitudinal study assessed hypothesized vulnerabilities of high perfectionism and low self-efficacy and the stressor of feeling overweight at Time 1 and then gathered weekly assessments of binge eating, vomiting, laxative use, fasting, and diet pill use for 11 weeks. As predicted, results showed that perfectionism, weight perception, and self-efficacy interacted to prospectively predict binge eating. In particular, women high in perfectionism who felt they were overweight and who had low self-efficacy reported the most number of weeks of binge eating. This interactive model did not predict inappropriate compensatory behaviors. Future directions and clinical implications are discussed.

Childhood maltreatment and college students' current suicidal ideation: a test of the hopelessness theory

Few studies have examined the relation between childhood maltreatment and adult suicidality within the context of a coherent theoretical model. The current study evaluates the ability of the hopelessness theory of depression's (Abramson, Metalsky, & Alloy, 1989) etiological chain to account for this relation in a sample of 297 undergraduates. Supporting the model, emotional, but not physical or sexual, maltreatment was uniquely related to average levels of suicidal ideation across a 2.5-year follow-up. Further, students' cognitive styles and average levels of hopelessness partially mediated this relation. Although these results cannot speak to causality, they support the developmental model evaluated.

Hopelessness as a mediator of the association between social support and depressive symptoms: findings of a study of men with HIV

Data from a prospective longitudinal study were used to investigate whether hopelessness mediates the association between social support and depression, as hypothesized by L. Y. Abramson, G. I. Metalsky, and L. B. Alloy (1989). Measures of hopelessness, social support, and depression were administered to 103 HIV-infected men and readministered 6 months later. Findings indicated that low baseline social support predicted increases in hopelessness and depression. Increases in hopelessness predicted increases in depression after controlling for baseline social support. Low baseline social support did not predict increased depression when hopelessness was controlled statistically.

Emotional, physical, and sexual maltreatment in childhood versus adolescence and personality dysfunction in young adulthood

The current study examined the unique relations of childhood and adolescent maltreatment (emotional, physical, and sexual) with DSM-III-R personality disorder (PD) dimensions in a sample of undergraduates. The results suggested that reported levels of childhood sexual maltreatment were uniquely related to six of the 11 PD dimensions examined. In contrast, reported levels of adolescent emotional maltreatment were uniquely related to only three PD dimensions and reported levels of adolescent physical maltreatment were uniquely related to only one PD dimension. Thus, whereas reported levels of adolescent emotional and physical maltreatment demonstrated some specificity to the various kinds of personality dysfunction, reported levels of childhood sexual maltreatment appeared to be related to more generalized personality dysfunction in young adulthood.

Development of gender differences in depression: an elaborated cognitive vulnerability-transactional stress theory

Descriptive epidemiological studies are reviewed, showing that the female preponderance in depression begins to emerge around age 13. A developmentally sensitive, elaborated cognitive vulnerability-transactional stress model of depression is proposed to explain the "big fact" of the emergence of the gender difference in depression. The elaborated causal chain posits that negative events contribute to initial elevations of general negative affect. Generic cognitive vulnerability factors then moderate the likelihood that the initial negative affect will progress to full-blown depression. Increases in depression can lead transactionally to more self-generated dependent negative life events and thus begin the causal chain again. Evidence is reviewed providing preliminary support for the model as an explanation for the development of the gender difference in depression during adolescence.

Hopelessness depression as a distinct dimension of depressive symptoms among clinical and non-clinical samples

Subtyping depression has been an interest of theorists and clinicians for at least four centuries. In this paper, we examined the validity of the symptom cluster component of the hopelessness theory of depression. We used structural equation modeling analyses on large samples of psychiatric outpatients (N=1604, 844, and 680) and Air Force cadets (N=1404) who completed the items of the Beck Depression Inventory (BDI). Findings were supportive of the hopelessness depression cluster as a distinct depressive syndrome. Implications for the nosology of depression and for depression theory were discussed.

Remitted depression studies as tests of the cognitive vulnerability hypotheses of depression onset: a critique and conceptual analysis

Investigations of cognitive patterns among individuals who have recovered from a depressive episode (i.e., remitted depressives) have figured importantly in evaluations of the validity of the vulnerability hypotheses of the cognitive theories of depression. However, we suggest that remitted depression studies as typically conducted and interpreted are inadequate tests of the cognitive vulnerability hypotheses of depression onset for four reasons: (1) remitted depression studies are based on the erroneous assumption that cognitive vulnerability should be an immutable trait; (2) remitted depression studies use a logically "backward" participant selection strategy in which participants are selected on the basis of the "dependent" variable (depression) and then compared on the "independent" variable (cognitive vulnerability), which is likely to result in heterogeneity of cognitive vulnerability among both the remitted depressed as well as the nondepressed groups given the causal relations specified in the cognitive theories of depression; (3) many remitted depression studies have ignored the possible activating role of stress in the cognitive vulnerability-stress theories, particularly Beck's theory, and thus, may attempt to assess cognitive vulnerability at a time when it is not operative (i.e., priming hypothesis); and (4) remitted depression studies inappropriately use postmorbid participants to test causal hypotheses, and therefore, are ambiguous about whether negative cognitive styles observed in remitted depressed persons are vulnerabilities as opposed to consequences of depression (i.e., scar hypothesis). As a remedy, we advocate the use of a theory-guided behavioral high-risk strategy to more adequately test the cognitive vulnerability hypotheses of depression onset.

The Temple-Wisconsin Cognitive Vulnerability to Depression Project: lifetime history of axis I psychopathology in individuals at high and low cognitive risk for depression

The authors tested the cognitive vulnerability hypotheses of depression with a retrospective behavioral high-risk design. Individuals without current Axis I diagnoses who exhibited either negative or positive cognitive styles were compared on lifetime prevalence of depressive and other disorders and the clinical parameters of depressive episodes. Consistent with predictions, cognitively high-risk participants had higher lifetime prevalence than low-risk participants of major and hopelessness depression and marginally higher prevalence of minor depression. These group differences were specific to depressive disorders. The high-risk group also had more severe depressions than the low-risk group, but not longer duration or earlier onset depressions. The risk group differences in prevalence of depressive disorders were not mediated by current depressive symptoms.

Perfectionism, perceived weight status, and self-esteem interact to predict bulimic symptoms: a model of bulimic symptom development

An interactive model of perfectionism, perceived weight status, and self-esteem was tested on 342 female undergraduates to predict bulimic symptoms. Using a longitudinal design, the authors tested the model on data collected at 2 points: the spring of participants' senior year of high school and during participants' first year of college. The authors hypothesized and found that self-esteem moderates the interaction between perfectionism and perceived weight status in predicting bulimic symptoms. Women who are high in perfectionism and who consider themselves overweight exhibit bulimic symptoms only if they have low self-esteem (i.e., if they doubt they can attain their high body standards). High self-esteem women with the same diathesis-stress conditions are less likely to exhibit bulimic symptoms. These findings clarify the role of perfectionism in bulimic symptomatology.

Development of gender differences in depression: description and possible explanations

This article reviews the description and possible explanations for the development of gender differences in depression in children and adolescents. The emerging gender difference (more girls depressed than boys) in depressed mood and depressive disorders appears after the age of 13 years or midpuberty. Currently, little evidence supports that biological factors are an explanation. Genetic factors are associated more strongly with depression among pubertal girls than boys. Regarding cognitive factors, ruminative response style, but not dysfunctional attitudes or attributional style, has been supported to be a possible explanation. Studies on childhood adversities and gender role have provided evidence explaining why more girls are depressed than boys. Girls are more likely to experience negative events in the family than boys, and these adversities are in turn associated with elevated depression. Girls identify more strongly with a feminine stereotype of needing to appear thin and consequently become more dissatisfied with their body shape and physical appearance, which in turn is associated with increased depression.

Depressogenic cognitive styles: predictive validity, information processing and personality characteristics, and developmental origins

Two of the major cognitive theories of depression, the theory of Beck [Beck, A. T. (1967). Depression: clinical, experimental and theoretical aspects. New York: Harper & Row. and Beck, A. T. (1987) Cognitive models of depression. Journal of Cognitive Psychotherapy: an International Quarterly, 1, 5-37] and the hopelessness theory [Abramson, Metalsky, & Alloy, (1989) Hopelessness depression: a theory-based subtype of depression. Psychological Review, 96, 358-372], include the hypothesis that particular negative cognitive styles increase individuals' likelihood of developing episodes of depression, in particular, a cognitively mediated subtype of depression, when they encounter negative life events. The Temple-Wisconsin Cognitive Vulnerability to Depression (CVD) project is a two-site, prospective longitudinal study designed to test this cognitive vulnerability hypothesis, as well as the other etiological hypotheses of Beck's and the hopelessness theories of depression. In this article, based on CVD project findings to date, we review evidence that the hypothesized depressogenic cognitive styles do indeed confer vulnerability for clinically significant depressive disorders and suicidality. In addition, we present evidence regarding moderators of these depressogenic cognitive styles, the information processing and personality correlates of these styles and the possible developmental antecedents of these styles. We end with a consideration of future research directions and the clinical implications of cognitive vulnerability to depression.

The dynamic self: how the content and structure of the self-concept change with mood

Change in the content and structure of the self-concept was examined in a 2-year prospective study of depression. A self-descriptive card-sorting task measured the self-concepts of participants who were either high or low in cognitive vulnerability to depression at 2 times, once when their mood was low and once when it was not. Analyses examined change in the positive and negative content of the self-concept and in 3 features of self-structure: differential importance, compartmentalization, and self-complexity. Findings suggest that change in the content of the self-concept simply reflects life circumstances, whereas change in self-structure may help to counteract stress and negative mood.

Suicidality and cognitive vulnerability to depression among college students: a prospective study

Using a behavioral high-risk two-site prospective design, we tested the cognitive vulnerability hypotheses about suicidality. Consistent with prediction, the high cognitive risk (HR) participants were more likely than the low cognitive risk (LR) participants to exhibit suicidality, measured by both structured diagnostic interview and questionnaire self-report, during the 2 1/2 year prospective follow-up period. Moreover, when the prospective period was examined as a whole, the mediation hypothesis derived from the cognitive theories was strongly supported. Hopelessness appeared to mediate the obtained relationship between cognitive vulnerability and suicidality. Finally, the obtained relationship between cognitive vulnerability and suicidality was not mediated by other hypothesized risk factors for suicidality not specified in the cognitive theories, such as past suicidality, personal history of depressive disorders, borderline and antisocial personality dysfunction, and parental history of depression.

Development of depression from preadolescence to young adulthood: emerging gender differences in a 10-year longitudinal study

The authors investigated the emergence of gender differences in clinical depression and the overall development of depression from preadolescence to young adulthood among members of a complete birth cohort using a prospective longitudinal approach with structured diagnostic interviews administered 5 times over the course of 10 years. Small gender differences in depression (females greater than males) first began to emerge between the ages of 13 and 15. However, the greatest increase in this gender difference occurred between ages 15 and 18. Depression rates and accompanying gender differences for a university student subsample were no different than for a nonuniversity subsample. There was no gender difference for depression recurrence or for depression symptom severity. The peak increase in both overall rates of depression and new cases of depression occurred between the ages of 15 and 18. Results suggest that middle-to-late adolescence (ages 15-18) may be a critical time for studying vulnerability to depression because of the higher depression rates and the greater risk for depression onset and dramatic increase in gender differences in depression during this period.

Negative reactions to depressive behaviors: a communication theories analysis

Interpersonal aspects of depression have received considerable research attention in the past 2 decades. This work often has been guided by J. C. Coyne's (1976b) interactional model of depression or P. M. Lewinsohn's (1974) social skill deficit theory of depression. A review of this research indicates that depressed people reliably experience rejection from those in their social environment and that depression generally is associated with impairments in social behavior. However, this research does not explain exactly what depressed people do to elicit rejection, or exactly why others react negatively to them. Research derived from communication theories on responsiveness, politeness, and expectations for nonverbal involvement illuminates the interpersonal cycle in depression. The role of these impairments in the cause, symptoms, course, subtypes, and therapy of depression is discussed.

Heterogeneity of cognitive style among depressed inpatients

An inference from the cognitive theories of depression is that only a subset of depressed individuals should exhibit distinctively negative cognitive styles. Although this inference has been supported by previous research, attempts to characterize these depressives have yielded few identifying variables. This study of psychiatric inpatients and normal control subjects identified several characteristics of depressives with very negative cognitive styles by (a) examining traditional depression subtypes, (b) grouping depressives on the basis of clinical observations, and (c) asking whether sex, developmental events, and history and severity of depression predict cognitive styles. We found that borderline personality disorder, negative family dynamics during childhood, a history of sexual abuse, and severity of depression predict cognitive styles. We speculate that aversive developmental events may contribute to cognitive vulnerability to depression.

Depressive reactions to failure in a naturalistic setting: a test of the hopelessness and self-esteem theories of depression

We tested the hopelessness and self-esteem theories of depression and an integration of the two by examining whether a stable, global attributional style (attributional diathesis) and low self-esteem interacted with the outcomes students received on a midterm examination to predict their subsequent depressive reactions over the course of 5 days. Students' immediate depressive reactions (on receipt of grades) were predicted solely by the examination outcome, whereas their enduring depressive reactions during the following 4 days were predicted by the Attributional Diathesis x Low Self-Esteem x Failure interaction. The results also indicated that the three-way interaction predicted enduring depressive reactions through the mediating role of hopelessness.

Schematic and situational determinants of depressed and nondepressed students' interpretation of feedback

We examined whether depressed persons' social skill deficits contribute to their negative cognitions and whether this contribution is independent of their negative schemata. Depressed (n = 60) and nondepressed (n = 60) subjects engaged in group discussions. We assessed subjects' social competence schemata with a questionnaire and subjects' actual level of social competence in the discussion through objective ratings made by codiscussants and outside observers. We found that independently of their negative schemata, depressed subjects' social skill deficits explained a significant portion of the variance in their more negative interpretation of feedback (relative to nondepressed subjects'). This suggests that real deficits in depressed persons' performance compound the effects of their negative schemata and further contribute to their negative cognitions. We also further explored findings by Dykman et al. (1989) and Lewinsohn et al. (1980).

Positive life events, attributional style, and hopefulness: testing a model of recovery from depression

A model of a recovery process from depression that is compatible with the hopelessness theory of depressive onset is proposed. This model predicts that depressives who have an enhancing attributional style for positive events (i.e., make global, stable attributions for such events) will be more likely to regain hopefulness and, thereby, recover from depression, when positive events occur. This prediction was tested by following a group of depressed college students longitudinally for 6 weeks. Although neither positive events alone nor attributional style alone predicted reduction in hopelessness, depressives who both showed the enhancing attributional style for positive events and experienced more positive events showed dramatic reductions in hopelessness which were accompanied by remission of depressive symptoms. Thus, attributional style for positive events may be a factor that enables some depressives to recover when positive events occur in their lives.

Processing of ambiguous and unambiguous feedback by depressed and nondepressed college students: schematic biases and their implications for depressive realism

Explored schematic processing as a mechanism for predicting (a) when depressed Ss would be negative relative to nondepressed Ss and (b) when depressed and nondepressed Ss would show biased or unbiased (i.e., "realistic") processing. Depressed and nondepressed Ss performed multiple trials of a task under conditions in which the two groups held either equivalent or different schemas regarding this task. Ss received either an unambiguous or objectively normed ambiguous feedback cue on each trial. In full support of schematic processing, depressed Ss showed negative encoding relative to nondepressed Ss only when their schemas were more negative, and both depressed and nondepressed Ss showed positively biased, negatively biased, and unbiased encoding depending on the relative feedback cue-to-schema match. Depressed and nondepressed Ss' response latencies to unambiguous feedback also supported the occurrence of schematic processing. We discuss the methodological, treatment, and "realism" implications of these findings and suggest a more precise formulation of Beck's schema theory of depression.

The hopelessness theory of depression: attributional aspects

In this article, we clarify, expand and revise the basic postulates of the hopelessness theory of depression (Abramson, Alloy & Metalsky, 1988a; Abramson, Metalsky & Alloy, 1987, 1988b; previously referred to as the reformulated helplessness theory of depression: Abramson, Seligman & Teasdale, 1978) and place the theory more explicitly in the context of work in descriptive psychiatry about the heterogeneity among the depressive disorders. We suggest that the hopelessness theory hypothesizes the existence in nature of an, as yet, unidentified subtype of depression--'hopelessness depression'--defined, in part, by its cause. We then give a critique of work conducted to test the hopelessness theory and explicate the limitations in research strategy associated with this line of work. Our critique includes a logical analysis that deduces the conceptual and methodological inadequacies of the research strategies used to test the theory. Finally, we suggest more adequate research strategies for testing the hopelessness theory and discuss conceptual and assessment issues that will arise in conducting such tests with special emphasis on attributional styles.

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 exams, their enduring depressive mood reactions were predicted solely by the hypothesized Attributional Diathesis X Outcome on Midterm Exam interaction. The direction and form of the interaction were in line with prediction. The results fully corroborated predictions derived from the mediation component of the theory as they applied to students' enduring mood responses.

Attributional style and the generality of learned helplessness

According to the logic of the attribution reformulation of learned helplessness, the interaction of two factors influences whether helplessness experienced in one situation will transfer to a new situation. The model predicts that people who exhibit a style of attributing negative outcomes to global factors will show helplessness deficits in new situations that are either similar or dissimilar to the original situation in which they were helpless. In contrast, people who exhibit a style of attributing negative outcomes to only specific factors will show helplessness deficits in situations that are similar, but not dissimilar, to the original situation in which they were helpless. To test these predictions, we conducted two studies in which undergraduates with either a global or specific attributional style for negative outcomes were given one of three pretreatments in the typical helplessness triadic design: controllable bursts of noise, uncontrollable bursts of noise, or no noise. In Experiment 1, students were tested for helplessness deficits in a test situation similar to the pretreatment setting, whereas in Experiment 2, they were tested in a test situation dissimilar to the pretreatment setting. The findings were consistent with predictions of the reformulated helplessness theory.

Illusion of control for self and others in depressed and nondepressed college students

Recently, it has been discovered that depressed people are less likely than nondepressed people to succumb to an "illusion of control" and judge that their actions influence outcomes that are objectively uncontrollable. This experiment examined the relationship between depression and susceptibility to the illusion of control for oneself and for others. Depressed and nondepressed college students were asked to judge either how much control they themselves had or how much control a male or female confederate had over a noncontingent, but positive, outcome. Replicating past findings on depression and judgments of control, depressed subjects judged relatively accurately that they exerted little control over the experimental outcome, whereas nondepressed subjects overestimated their personal control. Subjects' judgments of the confederates' control were a function of the subject's mood state and sex as well as of the confederate's sex. With one exception (depressed males in the male other condition), depressed subjects tended to overestimate the confederate's (male or female) control over the noncontingent outcome. Nondepressed females also judged that the confederate (male or female) exerted a high degree of control, thus succumbing to the illusion of control both for themselves and others. Nondepressed males, on the other hand, tended to judge more accurately that the confederate (particularly the female confederate) exerted little control and thus, succumbed to the illusion of control for themselves but not for others. These findings imply that an adequate understanding of depressive and nondepressive cognition requires an interpersonal as well as an intrapsychic perspective.

With one exception (depressed males in the male other condition), depressed subjects tended to overestimate the confederate's (male or female) control over the noncontingent outcome. Nondepressed females also judged that the confederate (male or female) exerted a high degree of control, thus succumbing to the illusion of control both for themselves and others. Nondepressed males, on the other hand, tended to judge more accurately that the confederate (particularly the female confederate) exerted little control and thus, succumbed to the illusion of control for themselves but not for others. These findings imply that an adequate understanding of depressive and nondepressive cognition requires an interpersonal as well as an intrapsychic perspective.

Problem-solving deficits and depressive symptoms among children

Depressive symptoms among 40 fourth- and fifth-grade students as measured by the Children's Depression Inventory, correlated highly with impaired problem solving at block designs (r = .64) and anagrams (r = .67). Similar impairments have been found among depressed adults, suggesting that depression among children may be continuous with depression among adults.

Attributional styles and life events in the classroom: vulnerability and invulnerability to depressive mood reactions

A core prediction of the reformulated model of learned helplessness and depression (Abramson, Seligman, & Teasdale, 1978) is that when confronted with the same negative life event, people who display a generalized tendency to attribute negative outcomes to internal, stable, or global factors should be more likely to experience a depressive mood reaction than people who typically attribute negative outcomes to external, unstable, or specific factors. We tested this prediction with a prospective design in a naturalistic setting by determining whether the content of college students' attributional styles at one point in time predicted the severity of their depressive mood response to receiving a low grade on a midterm exam at a subsequent point in time. Consistent with the prediction, students with an internal or global attributional style for negative outcomes at Time 1 experienced a depressive mood response when confronted with a subsequent low midterm grade, whereas students with an external or specific attributional style for negative outcomes were invulnerable to this depressive mood response. In contrast to the results for the internality and globality dimensions, students' scores along the stability attribution dimension were not correlated with the severity of their depressive mood response to the low midterm grade. In the absence of a negative life event (i.e., receipt of a high midterm grade), students' generalized tendencies to make internal or global attributions for negative outcomes at Time 1 were not significantly correlated with their subsequent changes in depressive mood although there was a nonsignificant positive correlation between severity of depressive mood response and the tendency to make global attributions for negative outcomes at Time 1.

Learned helplessness, depression, and the illusion of control

Do people previously exposed to uncontrollable aversive events, like naturally depressed people, fail to succumb to an illusion of control in a situation in which events occur noncontingently but are associated with success? Depressed and nondepressed college students were assigned to one of three groups that make up the typical triad used in studies of learned helplessness: controllable noises, uncontrollable noises, or no noises. Following pretreatment, subjects judged how much control they had in a noncontingency learning problem. For half of the subjects, events were noncontingent and associated with failure; whereas for the remaining subjects, events were noncontingent but associated with success. Contrary to the predictions of learned helplessness theory, nondepressed subjects previously exposed to uncontrollable noises showed a robust illusion of control in the condition in which events were noncontingent but associated with success, whereas nondepressed subjects previously exposed to controllable noises judged control accurately. Depressed subjects also judged control accurately regardless of their previous noise experience, The results were interpreted as consistent with the egotism hypothesis.

Depression, nondepression, and cognitive illusions: reply to Schwartz

In his comment, Schwartz argued that the Alloy and Abramson findings call into question the hypothesized causal link between learned helplessness and depression. Schwartz's contention is based on his interpretation of the Alloy and Abramson findings as showing that nondepressives cannot detect noncontingency. Although we argue that Schwartz has misinterpreted our data, we agree with his general contention that nondepressives may be relatively invulnerable to depression. We discuss the implications of our data for the learned helplessness theory as well as for other cognitive theories of depression. In addition, we evaluate Schwartz's intriguing motivational account of depressive accuracy in judging response-outcome contingencies. Finally, in response to Schwartz's question of whether nondepressives' errors in judging contingency are really errors at all, we suggest it is important to distinguish among error, irrationality, and maladaptiveness when discussing cognitive bias.
