Mood-congruent attentional bias in dysphoria: maintained attention to and impaired disengagement from negative information

Attentional bias to negative information has been proposed to be a cognitive vulnerability factor for the development of depression. In 2 experiments, the authors examined mood-congruent attentional bias in dysphoria. In both experiments, dysphoric and nondysphoric participants performed an attentional task with negative, positive, and neutral word cues preceding a target. Targets appeared either at the same or at the opposite location of the cue. Overall, results indicate that dysphoric participants show maintained attention for negative words at longer stimulus presentations, which is probably caused by impaired attentional disengagement from negative words. Furthermore, nondysphoric participants maintain their attention more strongly to positive words. These results are discussed in relation to recent developments in the pathogenesis and treatment of depression.     

Enhanced probing of attentional bias: The independence of anxiety-linked selectivity in attentional engagement with and disengagement from negative information

Cognitive models of anxiety posit that an attentional bias to negative information plays a causal role in elevated anxiety vulnerability and dysfunction. There has been considerable recent interest in determining whether this attentional bias reflects facilitated attentional engagement with and/or impaired attentional disengagement from negative information. We concur with the claim of investigators who have noted that the methodologies previously employed to dissociate engagement and disengagement biases are not optimal for this purpose. In the present study, we employ a novel methodology, the Attentional Response to Distal vs. Proximal Emotional Information (ARDPEI) task, which enables the discrete assessment of these two types of attentional selectivity. The findings demonstrate that facilitated attentional engagement with and impaired attentional disengagement from negative information both characterise elevated anxiety vulnerability. Further, these biases represent distinctive facets of anxiety-linked attentional selectivity. We discuss the potentially differing roles that engagement and disengagement biases may play in the development and/or maintenance of anxiety vulnerability and dysfunction.     

Components of attentional bias to threat in high trait anxiety: Facilitated engagement, impaired disengagement, and attentional avoidance

There is a wealth of evidence demonstrating enhanced attention to threat in high trait anxious individuals (HTA) compared with low trait anxious individuals (LTA). In two experiments, we investigated whether this attentional bias is related to facilitated attentional engagement to threat or difficulties disengaging attention from threat. HTA and LTA undergraduates performed a modified exogenous cueing task, in which the location of a target was correctly or incorrectly cued by neutral, highly and mildly threatening pictures. Results indicate that at 100 ms picture presentation, HTA individuals more strongly engaged their attention with and showed impaired disengagement from highly threatening pictures than LTA individuals. In addition, HTA individuals showed a stronger tendency to attentional avoidance of threat at the 200 and 500 ms picture presentation. These data provide evidence for differential patterns of anxiety-related biases in attentive processing of threat at early versus later stages of information processing.     

The attribution of value-based attentional priority in individuals with depressive symptoms

The capture of attention by stimuli previously associated with reward has been demonstrated across a wide range of studies. Such value-based attentional priority appears to be robust, and cases where reward feedback fails to modulate subsequent attention have not been reported. However, individuals differ in their sensitivity to external rewards, and such sensitivity is abnormally blunted in depression. Here, we show that depressive symptomology is accompanied by insensitivity to value-based attentional bias. We replicate attentional capture by stimuli previously associated with reward in a control sample and show that these same reward-related stimuli do not capture attention in individuals experiencing symptoms of depression. This sharp contrast in performance indicates that value-based attentional biases depend on the normal functioning of the brain's reward system and suggests that a failure to preferentially attend to reward-related information may play a role in the experience of depression.     

Emergence of attributional style and its relation to depressive symptoms

The development of depressive attributional style (AS) and its role as a cognitive diathesis for depression were examined in children and adolescents (Grades 2-9). In a 4-wave longitudinal study of 3 overlapping age cohorts, AS, negative life events, and depressive symptoms were evaluated every 12 months. Consistency of children's attributions across situations was moderately high at all ages. The cross-sectional structure of AS changed with age, as stability became a more salient aspect of AS than internality and globality. The structure of AS also changed, becoming more traitlike as children grew older. In longitudinal analyses, evidence of a Cognitive Diathesis x Stress interaction did not emerge until Grades 8 and 9, suggesting that AS may not serve as a diathesis for depression at younger ages. Results suggest that attributional models of depression may require modification before they are applied across developmental levels.     

Effects of tDCS over the right DLPFC on attentional disengagement from positive and negative faces: An eye-tracking study

The aim of this study was to increase insight in the neural substrates of attention processes involved in emotion regulation. The effects of right dorsolateral prefrontal cortex (i.e., DLPFC) stimulation on attentional processing of emotional information were evaluated. A novel attention task allowing a straightforward measurement of attentional engagement toward, and attentional disengagement away from emotional faces was used. A sample of healthy participants received 20 minutes of active and sham anodal transcranial direct current stimulation (i.e., tDCS) applied over the right DLPFC on 2 separate days and completed the attention task after receiving real or sham stimulation. Compared to sham stimulation, tDCS over the right DLPFC led to impairments in attentional disengagement from both positive and negative faces. Findings demonstrate a causal role of right DLPFC activity in the generation of attentional impairments that are implicated in emotional disturbances such as depression and anxiety.     

Receipt of negative feedback is related to increased negative feedback seeking among individuals with depressive symptoms

In recent years, numerous studies have demonstrated a link between positive and negative feedback seeking by depressed individuals, interpersonal rejection, and depression chronicity. Nonetheless, many of the specific interpersonal patterns underlying these links have yet to be clearly specified. One important lingering question concerns how depressed individuals respond to negative evaluation or feedback from others, because continued negative feedback seeking could place depressed people at risk for further rejection and continuation/exacerbation of depressive symptoms. Two studies were conducted to investigate the influence of negative feedback provisions from others on the feedback seeking behaviors of individuals with depressive symptoms. The results from Study 1 indicated an increased tendency to seek negative feedback among depressive individuals in association with an independent negative evaluation by their college roommates. Using a sample of newlywed couples, Study 2 extended this finding by demonstrating that, when directly provided with negative feedback from their spouses, individuals with depressive symptomatology actively sought further negative feedback, while those without such symptoms did not. Together, the results from these studies suggest that depressed individuals are likely to respond to negative evaluation and feedback from others with behaviors that could place them at risk for further rejection and continuing, if not worsening problems with depression.     

A developmental-contextual model of depressive symptoms in Mexican-origin female adolescents

The current study tested a developmental-contextual model of depressive symptomatology among Mexican-origin, female early and middle adolescents and their mothers. The final sample comprised 271 dyads. We examined the interrelations among cultural (i.e., acculturation dissonance), developmental (i.e., pubertal development and autonomy expectation discrepancies), and interpersonal (i.e., mother-daughter conflict and maternal supportive parenting) factors in predicting adolescents' depressive symptoms. For both early and middle adolescents, maternal support was negatively associated with mother-daughter conflict and depressive symptoms. Mother-daughter autonomy expectation discrepancies were positively associated with mother-daughter conflict, but this association was found only among early adolescents. Further, mother-daughter acculturation dissonance was positively associated with mother-daughter conflict but only among middle adolescents. Findings call for concurrently examining the interface of developmental, relational, and cultural factors in predicting female adolescents' depressive symptomatology and the potential differences by developmental stage (e.g., early vs. middle adolescence).     

The mediating role of self-esteem in the relationship between big five personality traits and depressive symptoms among Chinese undergraduate medical students

The objectives of this study were to examine the correlations between big five personality traits and depressive symptoms among Chinese undergraduate medical students, and to explore the mediating role of self-esteem on the correlations. Self-reported questionnaires, including Big Five Inventory, the Center for Epidemiologic Studies Depression Scale, Rosenberg’s Self-Esteem scale, and socio-demographic section were distributed to 2000 undergraduate medical students at four medical colleges and universities in Liaoning province, China, in June 2014. 1738 students became the final subjects. After adjustment for age and gender, agreeableness (β = −0.329) and openness (β = −0.096) were negatively related to depressive symptoms, while neuroticism (β = 0.245) was positively related to the symptoms. Self-esteem functioned as a mediator in the relationship between agreeableness (a * b = −0.154, 95% CI: −0.182, −0.127)/openness (a * b = −0.097, 95% CI: −0.124, −0.069)/neuroticism (a * b = 0.031, 95% CI: 0.007, 0.058) and depressive symptoms. Therefore, identifying at-risk students and undertaking appropriate intervention strategies that focus on both personality traits and self-esteem may be effective in preventing and reducing depressive symptoms among Chinese medical students.     

The stability of depressive symptoms in college students: An empirical demonstration of regression to the mean

In a recent paper, Vredenburg, Flett, and Krames (1993) hypothesized that the apparent instability of depressive symptom scores in college students may be due, in part, to the phenomenon known as statistical regression to the mean. This statistical principle was demonstrated in the current study. A sample of 183 university students completed the Beck Depression Inventory (BDI) at two timepoints separated by a 3-month interval. Consistent with past results, analyses revealed substantial changes in symptom scores over time with decrements being evident among many subjects with elevated symptom scores at Time 1. Examination of the amount of change over time in BDI scores indicated a pattern of findings that approximated the regression to the mean phenomenon. Statistical tests confirmed that regression to the mean accounted for a significant amount of the change in symptom scores over time. The implications of these findings are discussed in terms of the nature of depressive symptoms in students and the inappropriateness of assigning subjects to depressed or nondepressed groups on the basis of elevated scores on a self-report measure.     

The role of parent depressive symptoms in positive and negative parenting in a preventive intervention

This study examined the role of parent depressive symptoms as a mediator of change in behaviorally observed positive and negative parenting in a preventive intervention program. The purpose of the program was to prevent child problem behaviors in families with a parent who has current or a history of major depressive disorder. One hundred eighty parents and one of their 9- to 15-year-old children served as participants and were randomly assigned to a family group cognitive-behavioral (FGCB) intervention or a written information (WI) comparison condition. At two months after baseline, parents in the FGCB condition had fewer depressive symptoms than those in the WI condition, and these symptoms served as a mediator for changes in negative, but not positive, parenting at 6 months after baseline. The findings indicate that parent depressive symptoms are important to consider in family interventions with a parent who has current or a history of depression.

Illusion of control: invulnerability to negative affect and depressive symptoms after laboratory and natural stressors.

We examined whether individual differences in susceptibility to the illusion of control predicted differential vulnerability to depressive responses after a laboratory failure and naturally occurring life stressors. The illusion of control decreased the likelihood that subjects (N = 145) would (a) show immediate negative mood reactions to the laboratory failure, (b) become discouraged after naturally occurring negative life events, and (c) experience increases in depressive symptoms a month later given the occurrence of a high number of negative life events. In addition, the stress-moderating effect of the illusion of control on later depressive symptoms appeared to be mediated in part by its effect on reducing the discouragement subjects experienced from the occurrence of negative life events. These findings provide support for the hopelessness theory of depression and for the optimistic illusion-mental health link.     

An evaluation of early and late stage attentional processing of positive and negative information in dysphoria

Depressive disorders may be characterised by hyperattention toward negative information, hypoattention toward positive information, or a combination of both processing biases. In two studies, a dot-probe task was utilised to better ascertain the specific direction and time-course of these biases. In both studies, the dysphoric group showed significantly less attentional allocation toward positive stimuli than the non-dysphoric group. In study two, the dysphoric group also showed greater attentional allocation toward depression-specific stimuli. Importantly, the bias toward depression-specific stimuli, and the bias away from positive stimuli, were uncorrelated with each other. It may be that both biases can act as sufficient, but not necessary, characteristics of dysphoric processing. An additional possibility is that the relative level of each bias type may best characterise dysphoric processing. Each of these possibilities is discussed in turn.     

Synergistic effects of pain and alcohol use in relation to depressive and anxiety symptoms among Latinos in primary care

Although past work has shown that alcohol use co-occurs with anxiety/depression among Latinos, little work has examined the variables that qualify such associations. The present investigation sought to address whether pain severity (i.e. pain intensity and/or pain-related disability, respectively) moderated relations between hazardous drinking and depressive/anxious arousal symptoms among an economically disadvantaged Latino sample recruited from a primary care medical setting. Participants included 253 adult Latinos (M_age = 38.5 years, SD = 10.8; 86.6% female) who attended a community-based primary care clinic. There was a significant interaction of hazardous drinking with pain intensity in relation to depressive symptoms and significant interactions of hazardous drinking and pain-related disability in relation to depressive and anxious arousal symptoms. Hazardous drinking was associated with more severe depressive/anxious arousal symptoms only when pain intensity/disability was high. This is the first study to demonstrate the moderating role of pain intensity and disability in associations between hazardous drinking and anxiety/depression among Latinos in a primary care medical setting.     

手机成瘾与抑郁：社交焦虑和负性情绪信息注意偏向的多重中介作用

为考察手机成瘾与抑郁的关系, 研究同时整合情绪和认知两方面因素, 探讨了社交焦虑和负性情绪信息注意偏向在手机成瘾和抑郁之间的多重中介作用。研究1共有545名大学生完成了大学生手机成瘾倾向量表、贝克抑郁量表和社会交往焦虑量表。研究2选取51名大学生采用问卷法和2(配对面孔表情的情绪类型: 负性、中性) × 2(探测点位置: 与负性情绪面孔表情同侧、与负性情绪面孔表情异侧)的被试内实验设计。结果表明: (1)手机成瘾、社交焦虑和抑郁两两间存在显著正相关, 且社交焦虑在手机成瘾和抑郁之间起完全中介作用; (2)社交焦虑和负性情绪信息注意偏向在手机成瘾与抑郁的关系中起链式中介作用, 而负性情绪信息注意偏向在手机成瘾与抑郁间的单独中介效应不显著。具体而言, 手机成瘾通过两条路径影响抑郁: 一是社交焦虑的单独中介作用; 二是社交焦虑→负性情绪信息注意偏向的链式中介作用。     

A longitudinal study of gender differences in depressive symptoms from age 50 to 80

The Obvious Depression Scale was administered to 739 community residents at ages 50, 60, and 80 years, with 151 present at all waves. Although selective attrition influenced the level of depressive symptoms in cross-sectional vs. longitudinal samples, both sets of analyses revealed higher scores in women than in men at ages 50 and 60, but not at age 80. Men showed increases in depressive symptoms from age 60 to 80, but women did not (interaction p < .002). This interaction was not present in somatic symptoms, which increased across time in both genders. Potential explanations include differential changes in social roles with aging.     

Predictors of the first onset of a major depressive episode and changes in depressive symptoms across adolescence: stress and negative cognitions

This 6-year longitudinal study examined stressors (e.g., interpersonal, achievement), negative cognitions (self-worth, attributions), and their interactions in the prediction of (a) the first onset of a major depressive episode (MDE), and (b) changes in depressive symptoms in adolescents who varied in risk for depression. The sample included 240 adolescents who were first evaluated in Grade 6 (M = 11.86 years old; SD = 0.57; 54.2% female) and then again annually through Grade 12. Stressful life events and depressive diagnoses were assessed with interviews; negative cognitions and depressive symptoms were assessed with self-report questionnaires. Discrete time hazard modeling revealed a significant interaction between interpersonal stressors and negative cognitions, indicating that first onset of an MDE was predicted by high negative cognitions in the context of low interpersonal stress, and by high levels of interpersonal stressors at both high and low levels of negative cognitions. Analyses of achievement stressors indicated significant main effects of stress, negative cognitions, and risk in the prediction of an MDE, but no interactions. With regard to the prediction of depressive symptoms, multilevel modeling revealed a significant interaction between interpersonal stressors and negative cognitions such that among adolescents with more negative cognitions, higher levels of interpersonal stress predicted higher levels of depressive symptoms, whereas at low levels of negative cognitions, the relation between interpersonal stressors and depression was not significant. Risk (i.e., maternal depression history) and sex did not further moderate these interactions. Implications for intervention are discussed.     

Type A behavior and its relation to personality variables in Swedish male and female university students

A questionnaire based on the Jenkins Activity Survey (JAS), given to 181 male and 280 female Swedish university students, showed that females had significantly higher Type A scores than males. Three factors were extracted by factor analysis, two of which, "speed and impatience" and "hard-driving", corresponded to two of the factors obtained by JAS in an American population of employed men (Zyzanski & Jenkins, 1970). The third factor was tentatively termed "engagement-involvement". Twelve male and 12 female subjects from opposite ends of the distribution were compared in terms of 22 personality variables measured by questionnaires. It was found that Type A subjects of both sexes scored higher on scales measuring anxiety-proneness, aggression-hostility, extraversion and neuroticism.
