Impaired neuroendocrine response mediates refractoriness to cardiopulmonary resuscitation in spinal anesthesia

The authors hypothesized that excessive reassurance-seeking would prospectively predict changes in depressive symptoms, even controlling for changes in anxious symptoms, and would not predict changes in anxious symptoms controlling for changes in depressive symptoms. This prediction was supported in a study of 1,005 air force cadets. Participants completed measures of excessive reassurance-seeking and depressive and anxious symptoms before basic training, and completed symptom measures again following basic training. This study, together with others, demonstrates that excessive reassurance-seeking is an important depression-related variable that deserves serious attention as a potential vulnerability factor.     

Adolescent Girls' Interpersonal Vulnerability to Depressive Symptoms: A Longitudinal Examination of Reassurance-Seeking and Peer Relationships.

A transactional, interpersonal framework involving adolescents' reassurance-seeking and peer experiences may be useful for understanding the emergence of gender differences in depression prevalence during the adolescent transition. Sociometric nominations of peer acceptance/rejection and ratings of friendship quality provided by adolescents and their friends were used to measure peer experiences among 6th-8th-grade adolescents (N = 520) over 3 annual time points. After controlling for age and pubertal development, significant but small prospective effects offered mixed support for hypotheses: (a) depressive symptoms and negative peer relations predicted increasing levels of girls' reassurance-seeking; (b) initial levels of reassurance-seeking and depressive symptoms predicted deteriorating friendship quality among girls and low friendship stability, respectively; and (c) reassurance-seeking combined with poor peer experiences predicted increases in girls' depressive symptoms.

Attributional style and self-esteem; The prediction of emotional distress following a midterm exam.

A midterm design was used to determine whether students' attributional style for negative achievement events interacts with self-esteem and a lower-than-expected exam grade to predict changes in measures of specific and nonspecific depression and anxiety. Participants were 141 students who completed baseline measures of attributional style and self-esteem, as well as affective measures on several occasions before and after receipt of midterm grades. A pessimistic attributional style for negative events interacted with self-esteem and outcome to predict residual changes in a combined measure of nonspecific distress and anxious arousal (marginal trend) but not a combined measure of specific depressive symptoms. Unexpectedly, the greatest residual increases in distress occurred among low-self-esteem pessimists who experienced a nonfailure outcome. These effects did not appear to be mediated by changes in hopelessness. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Self-perceived competence and the relation between life events and depressive symptoms in adolescence: Mediator or moderator?

In a 2-wave longitudinal study, 9th-grade students (N ?=?468) completed self-report measures of stressful life events, depressive symptoms, and 5 domains of self-perceived competence (i.e., academic competence, social acceptance, physical appearance, behavioral conduct, and athletic competence). Teachers and peers also reported about the participants' depressive symptoms. In longitudinal analyses, negative (but not positive) events related to depressive symptoms. Results suggested that self-perceived competence served as a mediator (but not a moderator) of this relation. Negative events predicted changes in self-perceived competence. Self-perceived competence predicted changes in depressive symptoms. Also, the direct effect of negative events on depressive symptoms diminished after controlling for self-perceived competence.

Reassurance seeking, stress generation, and depressive symptoms: An integrative model.

The purpose of this study was to examine a mechanism through which interpersonal vulnerability factors may be linked with depressive symptoms by integrating a stress-generation model with an interpersonal theory of depression. The proposed conceptual framework was tested with 267 college students in a prospective structural equation model with 3 assessments over a 5-week period. Results supported all hypotheses. Initial depressive symptoms and initial reassurance seeking style were positively associated, and initial depressive symptoms were positively related to the occurrence of subsequent minor social stressors. Finally, a reassurance-seeking style was positively related to outcome depressive symptoms indirectly through minor social stressors. As predicted, stress generation operated as a mediating mechanism linking an initial reassurance-seeking style to subsequent depressive symptoms.

A preliminary study of perfectionism and loneliness as predictors of depressive and anxious symptoms in Latinas: A top-down test of a model.

In the present study, we used a top-down approach to examine perfectionism and loneliness as additive sociocognitive predictors of depressive and anxious symptoms in a sample of 121 Latina college students. Consistent with expectations, we found perfectionism and loneliness to be associated with both depressive and anxious symptoms. In addition, results of conducting hierarchical regression analyses indicated that certain dimensions of perfectionism, especially doubts about actions, accounted for significant variance in both depressive and anxious symptoms. Moreover, the inclusion of loneliness as a predictor was found to predict additional unique variance in both depressive and anxious symptoms beyond what was accounted for by perfectionism. Implications of the present findings for future research on negative affective conditions in Latinas are discussed. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Psychological factors and depressive symptoms in ischemic heart disease.

The aim of this study was to determine whether learned helplessness, cognitive distortions, self-efficacy, and dispositional optimism assessed at Time 1 (T1; questionnaires mailed at 1 month postdischarge) would predict depressive symptoms at Time 2 (T2; questionnaires mailed at 1-year follow-up) in a sample of 86 patients hospitalized with ischemic heart disease. Multiple regression results indicated that optimism and cognitive distortions at T1 were significantly associated with T1 depressive symptoms after controlling for confounding variables. When the T1 psychological factors were analyzed with T2 depressive symptoms, only optimism continued to predict depressive symptoms after controlling for confounds and T1 depressive symptoms. The global expectancies that optimism assessed appeared to be more stable over time than the statelike beliefs of cognitive distortions and may have accounted for why optimism predicted T2 depressive symptoms.

Child and parent reports of childhood anxiety: differences in coping styles

This study compares children anxious only on parent report (PR) with those anxious on self-report (SR) and self- and parent report (SPR) to examine the reasons for the reporting differences. Sixty-five children aged 7-12 years who met criteria for one or more Axis I anxiety disorders (25% with comorbid nonanxiety diagnoses) completed standardized measures of anxiety, depression, and coping style. Parents completed measures of child psychopathology and adult coping style. Assessing clinicians completed the Global Assessment of Functioning. All parents endorsed anxiety in their children. Based on their responses on standardized self-report measures of anxiety, children were classified as endorsing anxiety (SPR group) or not endorsing anxiety (PR group). Multivariate analysis of variance revealed that children in the SPR group endorsed more depression and employed a greater variety of coping strategies than children in the PR group. The two groups did not differ on parent or clinician measures. These findings suggest that reporting differences may be related to differences in coping styles in anxious children. SPR children may over report anxiety symptoms due to feelings of decreased self-worth associated with depressive thinking, whereas PR children may be able to distract themselves from their anxieties. The lack of difference in functioning between the two groups suggests that self-report anxiety questionnaire scores are not necessarily indicative of severity.     

Cognitions and stress: Direct and moderating effects on depressive versus externalizing symptoms during the junior high school transition.

This study examined direct and stress-moderating effects of attributional style and global self-worth on depressive and externalizing symptoms in adolescents. Attributional style, perceived self-worth, depressive symptoms, and externalizing behaviors were assessed in 371 students in the spring of 6th grade. After the transition to 7th grade, they again completed measures of depression and externalizing symptoms as well as measures of negative life events and school hassles. Stressors around the transition predicted both depressive and externalizing behaviors. Perceived self-worth predicted depressive symptoms, but not externalizing behaviors. Attributional style directly and in interaction with stressors predicted depressive symptoms and did not predict externalizing behavior. A 3-way interaction between stress, attributional style, and self-worth suggested that level of perceived self-worth may moderate the effects of attributional style in times of stress.

Mindfulness is associated with fewer PTSD symptoms, depressive symptoms, physical symptoms, and alcohol problems in urban firefighters.

Objective: This study investigated the association between mindfulness, other resilience resources, and several measures of health in 124 urban firefighters. Method: Participants completed health measures of posttraumatic stress disorder (PTSD) symptoms, depressive symptoms, physical symptoms, and alcohol problems and measures of resilience resources including mindfulness, optimism, personal mastery, and social support. The Mindful Awareness and Attention Scale (MAAS; Brown & Ryan, 2003) was used to assess mindfulness. Participants also completed measures of firefighter stress, number of calls, and years as a firefighter as control variables. Hierarchical multiple regressions were conducted with the health measures as the dependent variables with 3 levels of independent variables: (a) demographic characteristics, (b) firefighter variables, and (c) resilience resources. Results: The results showed that mindfulness was associated with fewer PTSD symptoms, depressive symptoms, physical symptoms, and alcohol problems when controlling for the other study variables. Personal mastery and social support were also related to fewer depressive symptoms, firefighter stress was related to more PTSD symptoms and alcohol problems, and years as a firefighter were related to fewer alcohol problems. Conclusions: Mindfulness may be important to consider and include in models of stress, coping, and resilience in firefighters. Future studies should examine the prospective relationship between mindfulness and health in firefighters and others in high-stress occupations.

Axis II symptomatology, depression, and life stress during the transition from adolescence to adulthood.

This study examined 2 models of the relationship between personality disorder symptomatology and depression, incorporating life stress as an intervening variable. In a community sample of late adolescent women, symptoms of Cluster B disorders predicted interpersonal chronic stress and self-generated episodic stress over 2 years, controlling for initial depression. Cluster A symptoms also predicted subsequent chronic interpersonal stress, over initial depression. Cluster C pathology did not predict subsequent stress. Personality disorder symptomatology was also associated with partner reported relationship dissatisfaction. Support was found for a mediation model whereby women with higher levels of initial personality disturbance in Clusters A and B generated excessive amounts of episodic stress and interpersonal chronic stress in the next 2 years, which, in turn, increased vulnerability for depressive symptoms. A moderation model, whereby the presence of greater personality disorder symptoms would increase the likelihood of depression in response to stress, was not supported.

Childhood depressive symptoms and adolescent cigarette use: A six-year longitudinal study controlling for peer relations correlates.

Objective: To examine potential pathways between childhood depressive symptoms and adolescent cigarette use, controlling for potential “third variable” causes. Design: Participants included 250 youth (60% girls) who were in Grades 4 to 6 at study outset and in Grades 10 to 12 (M age = 16.78) at a 6-year follow-up. At Time 1, children completed measures of depressive symptoms, as well as peer nominations of peer acceptance, rejection, and aggressive behavior. Main Outcome Measures: Time 2 measures included adolescents’ own and close friends’ cigarette use, depressive symptoms, and externalizing behaviors; parents also reported on adolescent behaviors. Results: Higher levels of childhood depressive symptoms and aggressive behavior were associated longitudinally with cigarette use in adolescence. After controlling for other associations, higher levels of childhood depressive symptoms also were associated with higher levels of friends’ cigarette use in adolescence and higher levels of adolescent depressive symptoms; each of these adolescent outcomes was concurrently associated with cigarette use. Conclusion: Depressive symptoms in childhood may lead to altered developmental trajectories that either directly or indirectly contribute to adolescent outcomes, including cigarette use.

Emotional self-disclosure and emotional avoidance: Relations with symptoms of depression and anxiety.

Research suggests that individuals with heightened symptoms of mood and anxiety disorders engage in diminished emotional disclosure. On the basis of emotion regulation theories, the authors hypothesized that this symptom–disclosure relationship would be mediated by the avoidance of emotional experience and expression. In Study 1, college students (N = 831) completed measures of depression and anxiety symptoms, measures of tendencies to avoid emotional expression, and measures of tendencies to self-disclose distress. Structural equation modeling revealed that anhedonic depression and anxious arousal were associated with lessened emotional self-disclosure tendencies as mediated by avoidance of emotional expression. In Study 2, participants (N = 153) completed new measures of depression and anxiety symptoms, reflected on the most significant emotional event experienced during the past week, and rated their avoidance of emotion about the event and their self-disclosure of the event. Depression (but not anxiety) symptoms were negatively related to the disclosure of a specific event, but avoidance of emotional experience did not mediate this depression–disclosure relationship. These findings extend emotion dysregulation theory and suggest that depressive symptoms in particular are associated with reduced emotional disclosure.

Cognitive vulnerability to depressive symptoms in adolescents in urban and rural Hunan, China: A multiwave longitudinal study.

The current multiwave longitudinal study examined the applicability of two cognitive vulnerability-stress models of depression—Beck's (1967, 1983) cognitive theory and the hopelessness theory (Abramson, Metalsky, & Alloy, 1989)—in two independent samples of adolescents from Hunan Province, China (one rural and one urban). During an initial assessment, participants completed measures assessing dysfunctional attitudes (Beck, 1967, 1983), negative cognitive style (Abramson et al., 1989), neuroticism (Costa & McCrae, 1992), depressive symptoms, and anxiety symptoms. Once a month for the subsequent 6 months, participants completed measures assessing the occurrence of different types of negative events, depressive symptoms, and anxiety symptoms. Results provided support for cognitive vulnerability factors as predictors of increases in depressive symptoms following the occurrence of higher than average levels of negative events in Chinese adolescents. The results also supported the specificity of these two cognitive vulnerability factors as predictors of depressive versus anxiety symptoms following the occurrence of higher than average levels of negative events (i.e., symptom specificity), and the ability of cognitive vulnerability factors to predict prospective change in depressive symptoms above and beyond the effects of trait neuroticism (i.e., etiological specificity).

A longitudinal look at the relation between depression and anxiety in children and adolescents.

Elementary school students (n?=?330) and their parents (n?=?228) participated in a 3-year longitudinal study of the temporal relation between anxiety and depressive symptoms in children. Every 6 months, children and parents completed depression and anxiety questionnaires for a total of 6 waves. Structural equation modeling revealed that individual differences on all measures were remarkably stable over time. Nevertheless, high levels of anxiety symptoms at 1 point in time predicted high levels of depressive symptoms at subsequent points in time even after controlling for prior levels of depression symptoms. These findings were consistent across self- and parent reports. Results support the temporal hypothesis that anxiety leads to depression in children and adolescents.

Self-esteem level and stability, admission functional status, and depressive symptoms in acute inpatient stroke rehabilitation.

Objectives: Explore the relationship of self-esteem level, self-esteem stability, and admission functional status on discharge depressive symptoms in acute stroke rehabilitation. Research Method: One hundred twenty stroke survivors serially completed a measure of state self-esteem during inpatient rehabilitation and completed a measure of depressive symptoms at discharge. Functional status was rated at admission using the Functional Independence Measure (FIM). Regressions explored main effects and interactions of self-esteem level and stability and admission FIM self-care, mobility, and cognitive functioning on discharge depressive symptoms. Results: After controlling for potential moderating variables, self-esteem level interacted with FIM self-care and cognitive functioning to predict discharge depressive symptoms, such that survivors with lower self-rated self-esteem and poorer functional status indicated higher levels of depressive symptoms. Self-esteem stability interacted with FIM mobility functioning, such that self-esteem instability in the presence of lower mobility functioning at admission was related to higher depressive symptoms at discharge. Implications: These results suggest that self-esteem variables may moderate the relationship between functional status and depressive symptoms. Self-esteem level and stability may differentially moderate functional domains, although this conclusion requires further empirical support.

Relationship satisfaction instability and depression.

In this study, we explored whether the degree of temporal instability in relationship satisfaction might add to our understanding of the well-documented association between relationship quality and depression. We hypothesized that greater relationship satisfaction instability would be associated with higher depressive symptoms, controlling for mean satisfaction levels. We conducted 12 weekly assessments of relationship satisfaction and depressive symptoms in a sample of 131 cohabiting and married women, and used intraindividual standard deviations of scores over the 12 weeks as an index of instability. Results indicated that, as hypothesized, relationship satisfaction instability predicted variance in depressive symptoms beyond that predicted by mean satisfaction; women whose weekly relationship satisfaction fluctuated more widely tended to have higher depressive symptoms. In comparison, temporal instability in depressive symptoms did not predict variance in relationship satisfaction beyond that predicted by mean depressive symptoms. Prospective analyses tentatively suggested that satisfaction instability may precede rather than follow elevated depressive symptoms. Results suggest the utility of assessing relationship satisfaction instability in future studies exploring links between marital quality and depression.

Depressive symptoms predict decline in perceptual speed in older adulthood.

Depressive symptoms and cognitive decline are associated in older age, but research is inconsistent about whether one condition influences the development of the other. We examined the directionality of relations between depressive symptoms and perceptual speed using bivariate dual change score models. Assessments of depressive symptoms and perceptual speed were completed by 1,206 nondemented older adults at baseline, and after 2, 8, 11, and 15 years. After controlling for age, education, baseline general cognitive ability, and self-reported health, allowing depressive symptoms to predict subsequent change in perceptual speed provided the best fit. More depressive symptoms predicted subsequently stronger declines in perceptual speed over time lags of 1 year. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Patterns of hemispheric perceptual asymmetries: Left hemispatial biases predict changes in anxiety and positive affect in undergraduate women.

Consistent with the tripartite model of anxiety and depression, hemispheric asymmetries may be differentially associated with depressive and anxious symptoms. Indeed, research has demonstrated that asymmetries do exist when examining hernispatial biases in both anxious and depressed individuals; however, the magnitude and direction of these asymmetries has been variable. The Chimeric Faces Task was used here to measure these asymmetries, along with measures for current and future levels of anxiety and depression. Results indicated that (a) increased left hemispatial biases at Time 1 predict increased anxiety (i,e., physiological hyperarousal) at Time 2 among 63 female undergraduate students (aged 18-47 yrs) and (b) decreased left hernispatial biases at Time 1 predict decreased positive affectivity at Time 2 among the same participants. The possibility that hemispatial biases represent a vulnerability to future anxiety and depression is discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Temporal variability in global self-esteem and specific self-evaluation as prospective predictors of emotional distress: Specificity in predictors and outcome.

Recent studies have found that temporal variability and reactivity in self-esteem (SE) are associated with risk for depressive symptoms subsequent to life stress. It is unclear, however, whether it is variability uniquely in SE that is critical, or whether variability in other domains, such as specific self-evaluation (SSE) and affect, would show similar effects. Further, the specificity of these effects to depression is unknown. In the present study, initially nondepressed women completed 7 daily ratings of SE, SSE, and affect. Over a 6-week prospective interval, the interactions of stressful life events and variability in both SE and SSE predicted changes in depression, particularly in individuals with more severe worst lifetime episodes of depressive symptoms. These effects were independent of average level of SE and SSE, as well as neuroticism and self-concept uncertainty. In contrast, variability in affect failed to predict changes in depression in interaction with life stress. Finally, none of the predictor variables interacted with stressful life events in predicting changes in anxiety. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
