Implicit depression and hopelessness in remitted depressed individuals

Cognitive theories of depression posit that automatically activated cognitive schemas, including negative thoughts about the self and the future, predispose individuals to develop depressive disorders. However, prior research has largely examined these constructs using explicit tests in currently depressed individuals. Using the Implicit Association Test (IAT), the present study examined automatic associations between the self and mood state ("depression IAT") and between the future and mood state ("hopelessness IAT") before and after a negative mood induction in 19 remitted depressed individuals and 23 healthy controls. In the depression IAT, remitted depressed participants exhibited an overall lower tendency to associate themselves with happiness relative to the healthy controls before the mood induction. Control, but not remitted depressed, participants' automatic associations between the self and happiness diminished following the mood induction. Contrary to our hypotheses, no significant findings emerged when considering the hopelessness IAT. Consistent with prior studies, no significant correlations emerged between implicit and explicit biases, suggesting that these measures probe different processes. Results extend prior IAT research by documenting the presence of a reduced tendency to associate the self with happiness in a sample at increased risk for depression.     

Self-esteem and depression revisited: implicit positive self-esteem in depressed patients?

The cognitive behavioural model of depression holds that negative cognitions related to the self have etiological importance for the maintenance and relapse of depression. This has been confirmed by research using questionnaires. Recent research using the Implicit Association Test, however, showed positive implicit self-esteem in formerly depressed participants, even after negative mood induction [Gemar, Segal, Sagrati, & Kennedy (2001). Mood-induced changes on the implicit association test in recovered depressed patients. Journal of Abnormal Psychology, 110, 282-289]. These results are not in line with cognitive theory of depression. Since this could be an artifact of the specific procedure that was used, we investigated implicit self-esteem of currently depressed participants and healthy controls using three different paradigms: The Implicit Association Test, the Name Letter Preference Task, and the Extrinsic Affective Simon Task. The results of the three experiments are unequivocally indicative of positive implicit self-esteem in currently depressed patients. However, it remains an intriguing question what exactly these indirect measures assess.     

Implicit but not explicit self-esteem predicts future depressive symptomatology

To date, research on the predictive validity of implicit self-esteem for depressive relapse is very sparse. In the present study, we assessed implicit self-esteem using the Name Letter Preference Task and explicit self-esteem using the Rosenberg self-esteem scale in a group of currently depressed patients, formerly depressed individuals, and never depressed controls. In addition, we examined the predictive validity of explicit, implicit, and the interaction of explicit and implicit self-esteem in predicting future symptoms of depression in formerly depressed individuals and never depressed controls. The results showed that currently depressed individuals reported a lower explicit self-esteem as compared to formerly depressed individuals and never depressed controls. In line with previous research, all groups showed a positive implicit self-esteem not different from each other. Furthermore, after controlling for initial depressive symptomatology, implicit but not explicit self-esteem significantly predicted depressive symptoms at six months follow-up. Although implicit self-esteem assessed with the Name Letter Preference Test was not different between formerly depressed individuals and never depressed controls, the findings suggest it is an interesting variable in the study of vulnerability for depression relapse.     

Self-esteem reconsidered: unstable self-esteem outperforms level of self-esteem as vulnerability marker for depression

Previous studies have built up evidence that an unstable self-esteem is associated with vulnerability to depression and that it outperforms level of self-esteem as a predictor for symptoms of depression. However, most of these studies have used student samples exclusively to investigate the role of self-esteem instability in depression vulnerability. Our present study used samples of currently depressed inpatients, formerly depressed individuals, and never-depressed controls to investigate the relationship between self-esteem instability and depression. In addition, we examined the predictive validity of self-esteem instability in predicting future depressive symptoms. The results indicate that self-esteem instability is associated with depression and vulnerability to depression. Furthermore, self-esteem instability interacted with perceived stress variability and depressed mood variability in predicting future depressive symptomatology at six months follow-up. These results are in line with the diathesis-stress model and support the hypothesis that self-esteem instability might be more important than level of self-esteem in predicting vulnerability to depression.     

Autobiographical memory characteristics in depression vulnerability: formerly depressed individuals recall less vivid positive memories

The differential activation hypothesis (DAH; Teasdale, 1988) proposes that individuals who are vulnerable to depression can be distinguished from non-vulnerable individuals by the degree to which negative thoughts and maladaptive cognitive processes are activated during sad mood. While retrieval of negative autobiographical memories is noted as one such process, the model does not articulate a role for deficits in recalling positive memories. Two studies were conducted to compare the autobiographical memory characteristics of never-depressed and formerly depressed individuals following a sad mood induction. In Study 1, features of negative memories of never-depressed and formerly depressed individuals did not differ, either in neutral or sad mood. For positive memories, groups did not differ in neutral mood, but following a sad mood induction, formerly depressed individuals rated their positive memories as less vivid than their never-depressed counterparts. Study 2 examined positive autobiographical memory features more comprehensively and replicated the finding that in a sad mood formerly depressed individuals recalled less vivid positive memories than never-depressed controls. These findings suggest that the phenomenological features of positive memories could represent an important factor in depressive vulnerability, and, more broadly, that depression may be associated with a deficit in the processing of positive material.

Mood-induced changes on the Implicit Association Test in recovered depressed patients

A mood induction paradigm was used to examine dysphoria-related changes in two types of cognitive processing in individuals who had previously experienced depression. Formerly depressed patients (n = 23) and never-depressed controls (n = 27) completed the Dysfunctional Attitudes Scale, a self-report measure of effortful processing, and performed the Implicit Association Test, an automatic-reaction time task that measures evaluative bias, before and after a negative-mood induction. The formerly depressed group showed both an increase in endorsement of dysfunctional attitudes and a more negative evaluative bias for self-relevant information after the induction, relative to controls--however, there was no association between the mood-linked changes observed on these two measures. The shift in evaluative bias shown by the formerly depressed group was similar to that seen in a group of 32 currently depressed individuals. These findings suggest that even a mild negative mood in formerly depressed individuals can reinstate some of the cognitive features observed in depression itself.     

Self-report measures of defeat and entrapment during a brief depressive mood induction

Recent studies have reported that depression is strongly associated with perceptions of defeat and entrapment, and have proposed that such perceptions are central features of depression. This study used experimental mood induction procedures to investigate the putative causal relationship between perceptions of defeat/entrapment and depressed mood. Two groups of female undergraduate volunteers (n = 16) completed visual analogue mood scales, as well as Defeat and Entrapment scales, before and after either a negative or a positive musical mood induction procedure (MIP). Scores on the Defeat and Entrapment Scales were significantly correlated with scores on the Beck Depression Inventory (BDI). The negative MIP caused a worsening of mood and significantly increased perceptions of defeat and entrapment, particularly internal entrapment. The positive MIP caused a small but significant improvement in mood, and significantly decreased defeat scores. Individuals with elevated BDI or internal entrapment scores prior to the negative MIP showed the greatest increases in internal entrapment after the negative mood induction. The results demonstrate that induction of a depressed mood increases perceptions of defeat and entrapment, and suggest that, in the case of internal entrapment, this effect increases with the initial level of depression or entrapment.     

Characteristic emotional intelligence and emotional well-being

Both theory and previous research suggest a link between emotional intelligence and emotional well-being. Emotional intelligence includes the ability to understand and regulate emotions; emotional well-being includes positive mood and high self-esteem. Two studies investigated the relationship between emotional intelligence and mood, and between emotional intelligence and self-esteem. The results of these studies indicated that higher emotional intelligence was associated with characteristically positive mood and higher self-esteem. The results of a third study indicated that higher emotional intelligence was associated with a higher positive mood state and greater state self-esteem. The third study also investigated the role of emotional intelligence in mood and self-esteem regulation and found that individuals with higher emotional intelligence showed less of a decrease in positive mood and self-esteem after a negative state induction using the Velten method, and showed more of an increase in positive mood, but not in self-esteem, after a positive state induction. The findings were discussed in the light of previous work on emotional intelligence, and recommendations were made for further study.     

轻微及中度抑郁者的积极自我

研究基于积极心理视角,考察抑郁个体在多个自我维度上,外显及内隐自尊的水平高低与稳定特性。被试选自高中学生,有效数据131人,分为抑郁(65人)与正常(66人)两组。所有被试在有/无应激两个时间点完成自我描述问卷II与改进内隐联想测验。结果发现,不论外显/内隐水平,抑郁个体倾向在指向个体内部的自我维度上具有积极自我,并且倾向在核心价值之外的自我维度上具有稳定自尊。由此证实,抑郁个体自我机制中的确存在积极成分。     

抑郁情绪大学生反应抑制的眼动特点

本研究采用反眼动实验范式,通过BDI和 SDS量表筛选11名抑郁情绪组和12名正常对照组被试,以高兴、中性和悲伤面孔图片作为实验材料,旨在探讨抑郁情绪大学生对情绪刺激的眼动抑制能力。结果发现：抑郁情绪组的正确眼跳反应时慢于正常组;反朝向眼跳任务中,抑郁情绪组在情绪面孔图片,尤其是悲伤面孔图片上的错误率比正常组高。研究表明,抑郁情绪个体的认知加工速度慢于正常个体,且对情绪面孔,尤其对悲伤面孔存在抑制缺陷。     

Self-focused attention, self-esteem, and the experience of state depression

The present experiment explored the effect of self-focused attention and self-esteem on self-reported state depression. Subjects completed a self-esteem scale before taking part in an exercise designed to induce either strong feelings of temporary depression (strong condition) or very mild feelings of temporary depression (weak condition). Before rating their mood, subjects waited for a short period either in the presence or absence of a mirror. A significant Depression Manipulation X Mirror-No Mirror interaction effect emerged: Subjects who waited in the presence of the mirror reported feeling more depressed in the strong condition and less depressed in the weak condition, relative to those who waited in the absence of the mirror. Moreover, this interaction effect was mainly attributable to the low self-esteem participants, rather than to the medium or high self-esteem individuals. Theoretical implications of these findings are discussed.     

Attributional Style and Depressive Mood Reactions

According to the reformulated learned helplessness model of depression, individuals who characteristically attribute negative events to internal-stable-global causes become depressed when confronted with negative life events. This proposition was tested in a field and a laboratory study in settings with an interpersonal, socially relevant character. In the field study, the attributional style of 86 female college students was investigated before Christmas, and their mood was recorded both before and after Christmas. The laboratory study recorded the mood of 46 female students before and after either success or failure. In both studies changes in depressive mood were predicted by the Attribution X Outcome interaction. The direction and form of the interaction were in line with the diathesis-stress model. In the field study, but not the laboratory study, outcome was a significant predictor of changes in depressive mood.     

The effects of unemployment on the mood,self-esteem,locus of control,and depressive affect of school-leavers

The purpose of this study was to investigate some psychological effects of unemployment in school-leavers using a longitudinal research design. Questionnaires which included mood questions and scales measuring self-esteem, locus of control and depressive affect, were administered twice to 761 students, once while they were at school, and then again one year later. Comparisons between the unemployed and employed groups revealed that the unemployed were generally less well-adjusted than their employed counterparts. Specifically they reported greater negative mood and had higher depression scores, and the unemployed girls also displayed lower self-esteem. These differences, however, resulted largely from an improvement in outlook on the part of the employed, rather than from the unemployed becoming more depressed and losing self-esteem.     

Depressed mood: The role of negative thoughts,self-consciousness,and sex role stereotypes

Research typically finds that depression is twice as common among women as among men. This may relate to differences in socialization that result in different emotions, cognitions, and coping reactions. Sex-role stereotypes, employment and marital status, and differential social pressures may also be significant in making women more vulnerable to the development of depression. Women may have less decision-making power, face more adverse life events, and have limited access to resources, which may lead to feelings of helplessness and low self-esteem. Low self-esteem and negative cognitions about the self in turn may be proximal factors predictive of negative mood. Additionally, women may be more prone to ruminative self-focus rather than active coping, a significant risk factor for depression. This study examined individual predictors of depressed mood for each sex, including coping, self-esteem, negative thoughts, self-consciousness (rumination), as well as social factors such as the endorsement of sex-role stereotypes and decision-making power in the family. Results indicated that social factors were not related to depressed mood in either sex, but were related to coping styles and self-esteem. Depressed mood was associated with individual characteristics, such as avoidant coping styles, social anxiety for women, and ruminative self-focus for men. Regression analysis showed that coping through denial and negative thoughts explained depressed mood, and the latter was particularly true for men. These results point to the significance of examining both individual and social factors when attempting to understand depression in men and women.     

Information processing and cognitive organization in unipolar depression: specificity and comorbidity issues

This study investigated information processing and cognitive organization in clinical depression. The specificity of various cognitive mechanisms to depression was also examined. Twenty-six depressed/anxious individuals, 24 pure depressives, 25 never-depressed anxious controls, and 25 nonpsychiatric controls completed a modified Stroop task, the Self-Referent Encoding Task, and two tasks designed to assess cognitive structure. Comorbid depressed/anxious, depressed, and anxious groups performed similarly to one another but differed significantly from nonpsychiatric controls, on the processing and organization of negative content. Specificity to depression was also obtained, as both depressed groups endorsed and recalled less positive information and organized positive self-relevant information with less interconnectedness than anxious individuals and nonpsychiatric controls. These results suggest that depressed individuals have an interconnected negative self-representational system and lack a well-organized positive template of self. These findings are discussed in terms of cognitive models of depression and the tripartite model of depression and anxiety.     

Automatic and effortful processing of self-statements in depression

Clark and Beck (1999) and Williams et al. (1997) have come up with quite different conclusions regarding which cognitive processes are most affected by negative self-schemata and negative knowledge structures. In order to increase the understanding of differences in effortful and automatic processing in depression, we compared never depressed (ND), previously depressed (PD) and clinically depressed (CD) individuals on free recall, recognition and fabrication of positive and negative self-statements. The results showed that: (i) overall NDs and PDs recalled more positive self-statements than CDs, whereas CDs correctly recognized more negative self-statements than NDs and PDs; and (ii) CDs and PDs fabricated more negative than positive self-statements, whereas no difference was obtained for NDs. The results seem to be in line with Clark and Beck's suggestions. However, there are several aspects of the present findings that make the picture more complicated.     

Mood and memories of parental rearing styles: A comparison of mood effects on questionnaire-cued and free recall of autobiographical memories

The relationship between memories of childhood experiences (e.g., adverse parenting) and adult depression often found raises questions of interpretation. On the one hand, both laboratory studies and clinicians' experiences suggest that subjects in a depressed mood frequently show a negative bias in perceptions and memories. Negative childhood memories in depressed persons might, therefore, be interpreted as epiphenomena of depressed mood instead of etiological factors. On the other hand, memories of childhood experiences seem remarkably stable across changes in depressed mood, especially when memories are elicited by means of standardized questionnaires. In the mood and memory literature several explanations for this stability are offered. For one thing, highly structured cues to elicit memories (such as in questionnaires) are hypothesized to be less susceptible to mood bias than unstructured memory cues (such as in free recall procedures). On the other hand, resource allocation theorists suggest that childhood memories, being well established and rehearsed, are relatively impervious to mood bias no matter how they are elicited. In this study we examined whether different methods of eliciting childhood memories (i.e., free recall and questionnaire-cued) are differentially susceptible to mood bias. To this aim, we used a mood induction procedure to induce depressed, neutral, and elated mood and assessed childhood memories both before and after the mood induction using both questionnaires and free recall to elicit memories. Results suggested that memories elicited by means of free recall as well as by means of questionnaire-cued recall were susceptible to depressed and elated mood bias. The implications for research addressing the link between childhood experiences and depression are discussed.     

抑郁的内隐认知与治疗

认知模型认为抑郁个体存在认知加工的偏向,但是,相对于外显认知,抑郁的内隐认知研究较少。现有研究表明：抑郁个体沉迷于特定的内隐认知偏向：抑郁个体倾向于注意环境中的负性刺激;在概念驱动内隐记忆测验中表现出偏向;更可能呈现出无望感的内隐态度。内隐认知可能是抑郁个体维持抑郁的重要因素,在治疗中,可采用知觉内隐认知、扩展功能失调思维记录、记忆日志和增进注意控制等认知技术改变抑郁患者的内隐认知偏向。
