Expressive inhibition in response to stress: Implications for emotional processing following trauma

Expressive inhibition – the willful restriction of expressed emotion – is documented in individuals reporting trauma-related distress, but its impact on global affective functioning remains unclear. Theoretical models propose that chronic activation of negative emotion and deliberate restriction of affect operate synergistically to produce trauma-related emotional deficits. The current project examined the impact of these factors on subjective experience and physiological activation following exposure to an analog trauma. University students (N = 192; M_age = 20, 57% female, 42% White/Non-Hispanic) viewed a graphic film depicting scenes of a televised suicide. Participants then viewed either a sadness- or humor-eliciting film under instructions to inhibit [n_sadness = 45, n_humor = 52] or naturally express emotion [n_sadness = 48, n_humor = 47]. Expressive inhibition was associated with restricted amusement specifically among participants viewing the humor film. Inhibition also produced attenuated sympathetic and parasympathetic recovery, irrespective of film assignment. Evidence of disruptions in emotional processing supports models identifying inhibition as a possible mechanism in post-trauma affect dysregulation.     

Positive emotion dysregulation and posttraumatic stress disorder symptoms: Investigating the role of anxiety sensitivity

ObjectivePosttraumatic stress disorder (PTSD) symptoms are prevalent and deleterious among individuals who have experienced a sexual assault. Although an emerging field of research has established a link between positive emotion dysregulation and PTSD symptoms, there is a limited understanding of mechanisms underlying this relation. Individuals who have experienced a sexual assault may begin to fear any arousal-related sensations via stimulus generalization, including that associated with positive emotions, which, in turn, may amplify PTSD symptoms. Thus, the current study examined the role of anxiety sensitivity in the association between positive emotion dysregulation and PTSD symptoms.MethodsA sample of 500 community members reporting a history of sexual assault (M_age = 34.54, 54.4% male, 79.0% white) completed measures of positive emotion dysregulation, anxiety sensitivity, and PTSD symptoms.ResultsFindings detected a significant indirect effect of anxiety sensitivity in the relation between positive emotion dysregulation and PTSD symptoms (β = 0.28, SE = 0.03, 95% CI [0.22, 0.34]). Supplementary analyses revealed that effects held for subscales of anxiety sensitivity (i.e., cognitive, physical, social concerns) and PTSD symptom clusters (i.e., intrusions, avoidance, negative alternations in cognitions and mood, alternations in arousal and reactivity).ConclusionsThis study offers preliminary empirical support for the assertion that fear of arousal-related sensations associated with positive emotions may partially explain the link between positive emotion dysregulation and PTSD symptoms among those who have experienced a sexual assault. Information from this study could advance future research and treatment.     

Parenting strategies and socio-cultural influences in childhood anxiety: Mexican,Latin American descent,and European American families

This study examined the relationship between anxiety in Latin American children and Latino cultural schemas, parenting strategies, being an ethnic minority, and assimilation. Latin American (n = 72; LA) and white European-American (n = 46; EA) children living in the U.S., Mexican children living in Mexico (n = 99; M), and at least one parent per family (n = 283) were administered measures assessing anxiety, parenting strategies, collectivism, family cohesion, simpatia, parent–child communication, and assimilation. M and LA children expressed more anxiety symptoms than EA children. More mother control and less father acceptance were associated with childhood anxiety across all three groups. However, father control was associated with more anxiety for the EA group but not the MA group, and mother acceptance was associated with more anxiety for the EA and MA groups but with less anxiety for the M group. Family cohesion was negatively associated with children's anxiety independent of ethnic group. Finally, differing from parents in assimilation did not influence LA children's anxiety.     

Skittish,shielded, and scared: Relations among behavioral inhibition,overprotective parenting,and anxiety in native and non-native Dutch preschool children

This study examined behavioral inhibition and overprotective parenting as correlates and predictors of anxiety disorder symptoms in preschoolers with a multi-cultural background (N = 168). Parents of 3- to 6-year-old children completed a set of questionnaires twice, 12 months apart. Parents were also interviewed with the Anxiety Disorders Interview Schedule for DSM-IV at the 12-month point to assess the clinical severity of children's anxiety symptoms. Behavioral inhibition consistently emerged as a significant concurrent correlate of anxiety symptoms and this was particularly true for social anxiety symptoms. Overprotective parenting also emerged as a significant correlate of anxiety, but only in the case of non-social anxiety symptoms and mainly in non-native Dutch children. Prospective analyses revealed that behavioral inhibition was a significant predictor of social anxiety symptoms, while overprotective parenting did not explain significant variance in the development of children's anxiety over time. The support for an interactive effect of behavioral inhibition and overprotective parenting was unconvincing. Finally, it was found that children who exhibited stable high levels of behavioral inhibition throughout the study ran the greatest risk for developing an anxiety disorder.     

An examination of the incremental contribution of emotion regulation difficulties to health anxiety beyond specific emotion regulation strategies

Given the potential transdiagnostic importance of emotion dysregulation, as well as a lack of research examining emotion dysregulation in relation to health anxiety, the present study sought to examine associations among specific emotion regulation strategies (cognitive reappraisal and expressive suppression), emotion regulation difficulties, and health anxiety in a physically healthy sample of adults (N = 482). As hypothesized, results of a series of hierarchical multiple regression analyses showed that emotion regulation difficulties provided a significant incremental contribution, beyond the specific emotion regulation strategies, in predicting each of the three health anxiety variables. Among the six dimensions of emotion regulation difficulties, the dimension representing perceived access to effective emotion regulation strategies was the only emotion regulation difficulty dimension that predicted all three health anxiety variables beyond the effects of the specific emotion regulation strategies. Results indicate that emotion regulation difficulties, and particularly one's subjective appraisal of his/her ability to effectively regulate emotions, may be of importance to health anxiety. Clinical implications are discussed.     

Family environment as a moderator of the association between anxiety and suicidal ideation

The present study examined associations among anxiety symptoms, anxiety disorder diagnoses, perceptions of family support and conflict, and suicidal ideation (SI) in a clinical sample of psychiatrically hospitalized adolescents. Participants were 185 adolescents (72% female; 84% white, mean age = 15.02 years, SD = 1.33) hospitalized on an acute psychiatric inpatient unit. Results indicated that anxiety disorders and symptoms were positively associated with SI, even after controlling for mood disorder diagnoses and sex. Moreover, this relationship was stronger among youth who reported lower (versus higher) levels of family support. Family conflict was positively associated with SI but did not moderate the relationship between anxiety and SI. Results suggest that family support may represent an important intervention target to decrease suicide risk among anxious youth. Integrating positive parenting techniques (e.g., attending to positive behaviors, providing praise, emotion coaching) and effective parent-child communication into treatment with anxious youth may help achieve this aim.     

Parenting practices,interpretive biases,and anxiety in Latino children

A number of factors are believed to confer risk for anxiety development in children; however, cultural variation of purported risk factors remains unclear. We examined relations between controlling and rejecting parenting styles, parental modeling of anxious behaviors, child interpretive biases, and child anxiety in a mixed clinically anxious (n = 27) and non-clinical (n = 20) sample of Latino children and at least one of their parents. Families completed discussion-based tasks and questionnaires in a lab setting. Results indicated that child anxiety was: linked with parental control and child interpretative biases, associated with parental modeling of anxious behaviors at a trend level, and not associated with low parental acceptance. Findings that controlling parenting and child interpretive biases were associated with anxiety extend current theories of anxiety development to the Latino population. We speculate that strong family ties may buffer Latino children from detrimental effects of perceived low parental acceptance.     

Parental adjustment,parenting attitudes and emotional and behavioral problems in children with selective mutism

The present study investigated emotional and behavioral problems in children with selective mutism (SM) along with the psychological adjustment and parenting attitudes of their mothers and fathers. Participants included 26 children with SM (mean age = 8.11 ± 2.11 years), 32 healthy controls (mean age = 8.18 ± 2.55 years) and the parents of all children. Children with SM displayed higher problem scores than controls in a variety of emotional and behavioral parameters. They predominantly displayed internalizing problems, whereas aggressive and delinquent behavior was described among a subsample of the children. Significant differences existed between the SM and control groups only in paternal psychopathology, which included anxiety and depression. They did not differ with respect to maternal psychological distress or mother or father reported parental attitudes. Another important result of the present study was that the severity of emotional and behavioral problems of children with SM was correlated with maternal psychopathology but not paternal psychopathology.     

Pain-related anxiety and anxiety sensitivity across anxiety and depressive disorders

Fear–anxiety–avoidance models posit pain-related anxiety and anxiety sensitivity as important contributing variables in the development and maintenance of chronic musculoskeletal pain [Asmundson, G. J. G, Vlaeyen, J. W. S., & Crombez, G. (Eds.). (2004). Understanding and treating fear of pain. New York: Oxford University Press]. Emerging evidence also suggests that pain-related anxiety may be a diathesis for many other emotional disorders [Asmundson, G. J. G., & Carleton, R. N. (2005). Fear of pain is elevated in adults with co-occurring trauma-related stress and social anxiety symptoms. Cognitive Behaviour Therapy, 34, 248–255; Asmundson, G. J. G., & Carleton, R. N. (2008). Fear of pain. In: M. M. Antony & M. B. Stein (Eds.), Handbook of anxiety and the anxiety disorders (pp. 551–561). New York: Oxford University Press] and appears to share several elements in common with other fears (e.g., anxiety sensitivity, illness/injury sensitivity, fear of negative evaluation) as described by Reiss [Reiss, S. (1991). Expectancy model of fear, anxiety, and panic. Clinical Psychology Review, 11, 141–153] and Taylor [Taylor, S. (1993). The structure of fundamental fears. Journal of Behavior Therapy and Experimental Psychiatry, 24, 289–299]. The purpose of the present investigation was to assess self-reported levels of pain-related anxiety [Pain Anxiety Symptoms Scale-Short Form; PASS-20; McCracken, L. M., & Dhingra, L. (2002). A short version of the Pain Anxiety Symptoms Scale (PASS-20): preliminary development and validity. Pain Research and Management, 7, 45–50] across several anxiety and depressive disorders and to compare those levels to non-clinical and chronic pain samples. Participants consisted of a clinical sample (n = 418; 63% women) with principal diagnoses of a depressive disorder (DD; n = 22), panic disorder (PD; n = 114), social anxiety disorder (SAD; n = 136), obsessive-compulsive disorder (OCD; n = 86), generalized anxiety disorder (GAD; n = 46), or specific phobia (n = 14). Secondary group comparisons were made with a community sample as well as with published data from a treatment-seeking chronic pain sample [McCracken, L. M., & Dhingra, L. (2002). A short version of the Pain Anxiety Symptoms Scale (PASS-20): preliminary development and validity. Pain Research and Management, 7, 45–50]. Results suggest that pain-related anxiety is generally comparable across anxiety and depressive disorders; however, pain-related anxiety was typically higher (p < .01) in individuals with anxiety and depressive disorders relative to a community sample, but comparable to or lower than a chronic pain sample. Results imply that pain-related anxiety may indeed be a construct independent of other fundamental fears, warranting subsequent hierarchical investigations and consideration for inclusion in treatments of anxiety disorders. Additional implications and directions for future research are discussed.     

An evaluation of anxiety sensitivity,emotional dysregulation,and negative affectivity among daily cigarette smokers: Relation to smoking motives and barriers to quitting

The present investigation evaluated the relations between anxiety sensitivity and motivational bases of cigarette smoking, as well as barriers to quitting smoking, above and beyond concurrent substance use, negative affectivity, and emotional dysregulation among a community sample of 189 daily cigarette smokers (46% women; M_age = 24.97 years, SD = 9.78). Results indicated that anxiety sensitivity was significantly related to coping, addictive, and habitual smoking motives, as well as greater perceived barriers to quitting. These effects were evident above and beyond the variance accounted for by concurrent tobacco, alcohol, and marijuana use and discernable from shared variance with negative affectivity and emotional dysregulation. Emotional dysregulation was significantly related to stimulation, habitual, and sensorimotor smoking motives and greater perceived barriers to quitting, whereas negative affectivity was only significantly related to smoking for relaxation. These findings uniquely add to a growing literature suggesting anxiety sensitivity is an important and unique cognitive factor for better understanding clinically-relevant psychological processes related to cigarette smoking.     

Emotion regulation strategies mediate the associations of positive and negative affect to upper extremity physical function

BackgroundThe Gross process model of emotion regulation holds that emotion-eliciting situations (e.g. musculoskeletal illness) can be strategically regulated to determine the final emotional and behavioral response. Also, there is some evidence that innate emotional traits may predispose an individual to a particular regulating coping style.MethodsWe enrolled 107 patients with upper extremity musculoskeletal illness in this cross-sectional study. They completed self-report measures of positive and negative affect, emotion regulation strategies (cognitive reappraisal and expressive suppression), upper extremity physical function, pain intensity, and demographics. We used Preacher and Hayes' bootstrapping approach to process analysis to infer the direct effect of positive and negative affect on physical function as well as their indirect effects through activation of emotion regulation strategies.ResultsNegative affect was associated with decreased physical function. The association was partly mediated by expressive suppression (b (SE) = −.10 (.05), 95% BCa CI [−.21, −.02]). Positive affect was associated with increased physical function. Cognitive reappraisal partially mediated this association (b (SE) = .11 (.05), 95% BCa CI [.03, .24]). After controlling for pain intensity, the ratio of the mediated effect to total effect grew even larger in controlled model comparing to uncontrolled model (33% vs. 26% for expressive suppression and 32% vs. 30% for cognitive reappraisal).ConclusionsThe relationships between affect, emotion regulation strategies and physical function appear to be more dependent on the emotional response to an orthopedic condition rather than the intensity of the nociceptive stimulation of the pain. Findings support integration of emotion regulation training in skill-based psychotherapy in this population to mitigate the effect of negative affect and enhance the influence of positive affect on physical function.     

Inflammatory biomarkers and emotional approach coping in men with prostate cancer

ObjectiveEmotion-regulating coping is associated with improvements in psychological and physical health outcomes. Yet in the context of prostate cancer-related stressors, limited research has characterized associations of emotion-regulating coping processes (emotional expression, emotional processing) and inflammatory processes that are related to disease risk. This investigation examined the relation of Emotional Approach Coping (EAC) with markers of inflammation to test the hypothesis that higher EAC scores at study entry (T1) would be associated with lower proinflammatory markers four months later (T2), specifically sTNF-RII, CRP, and IL-6.MethodsForty-one men (M age = 66.62 years; SD = 9.62) who had undergone radical prostatectomy or radiation therapy for localized prostate cancer within two years completed questionnaires, including assessments of EAC, at T1, and provided blood samples for immune assessments at T2.ResultsWhen controlling for relevant biobehavioral controls, emotional processing predicted lower IL-6 (B = −.66, p < .01), sTNF-RII (B = −.43, p < .05), and CRP (B = −.43, p < .10), whereas emotional expression was significantly associated with higher levels of sTNF-RII (B = .55, p < .05). Associations of emotional expression and IL-6 (B = .38, p < .10), and CRP (B = .44, p < .10) approached significance. Probing interactions of emotional processing and expression (though only approaching significance) suggested that expression of emotion is associated with higher inflammation (CRP and sTNF-RII) only in the context of low emotional processing.ConclusionsAttempts at emotion regulation via emotional processing appear to modulate inflammatory processes. Understanding, making meaning of, and working through emotional experience may be a promising target of intervention to reduce inflammation with potential effects on psychological and cancer outcomes in men with prostate cancer.     

The search for universal transdiagnostic and trans-therapy change processes: Evidence for intolerance of uncertainty

The search for universal processes associated with symptom change across emotional disorders and different forms of psychotherapy offers hope of increased theoretical parsimony and treatment efficiencies. This study investigated whether intolerance of uncertainty (IU) is a universal process by examining whether changes in IU were associated with changes in symptoms across three different cognitive behavior therapy protocols for depression (n = 106), social anxiety disorder (n = 88), or generalized anxiety disorder (n = 62) in a community mental health clinic. IU was associated with reductions in repetitive negative thinking in all treatments, which is consistent with IU being a transdiagnostic and ‘trans-therapy’ process of change. Changes in IU were also associated with symptom relief in the social anxiety disorder and generalized anxiety disorder groups, but not in the depression group. Implications of these findings are discussed within the broader literature of transdiagnostic approaches to emotional disorders.     

The importance of self-regulation for the school and peer engagement of children with high-functioning autism

This study examined individual differences in self-regulation, emotional and behavioral school engagement, and prosocial peer engagement in a sample of 40 children that included children with high functioning autism (HFA; n = 20) and their typical peers (n = 20). Children were 54.57 months on average at recruitment. Measures of self-regulation included parents’ reports of emotion regulation, effortful control, and executive function; direct observations of executive function skills; and observations of joint engagement during a parent–child interaction. Parents reported on school and prosocial peer engagement approximately one year later. Children with HFA had significantly impaired self-regulation, and decreased school and peer engagement. Executive function predicted both emotional and behavioral school engagement, whereas emotion regulation predicted prosocial peer engagement. The relation between effortful control and subsequent prosocial peer engagement was moderated by diagnostic group, suggesting it served a protective function for behaviors of children with HFA in the school setting.     

Influence of age,thought content,and anxiety on suppression of intrusive thoughts

Understanding differences in responses following attempts to suppress versus simply monitor intrusive thoughts is important given the established relationship between intrusive thinking and numerous forms of psychopathology. Moreover, these differences may vary as a function of age. Because of the links between aging and both enhancement in emotion regulation skills and decline in inhibition skills, older and younger adults were expected to differ in their responses (e.g., experience of negative affect and thought recurrence) to attempts at suppressing intrusive thoughts. This study examined whether efforts to suppress thought content that varied in valence and age-relevance differentially affected older (N = 40, aged 66–92) and younger (N = 42, aged 16–25) adults’ ability to inhibit intrusive thought recurrence and their resulting negative affect. Interestingly, older adults experienced less recurrence for most thoughts than younger adults. Also, for several dependent variables (negative affect and perceived difficulty suppressing intrusive thoughts), older adults showed less decline in their magnitude of response across thinking periods (i.e., from suppression to monitoring) than did younger adults. These age effects were not generally moderated by level of trait anxiety, though higher anxiety did predict intrusive thought responding in expected directions, such as greater negative affect. These findings point to independent influences of age and anxiety, and suggest a complex mix of risk and protective factors for older adults’ responses to intrusive thoughts.     

Prevalence and quality of anxiety in patients with epilepsy

BackgroundDepression and anxiety are the most frequent psychiatric disorders identified in patients with epilepsy. We aimed to determine the prevalence of state and trait anxiety in patients with epilepsy compared with people without epilepsy.MethodsWe recruited patients and healthy controls in the outpatient neurology clinic of Kurdistan University of Medical Sciences, Iran, during 2011. Eighty-four patients with epilepsy and 168 healthy persons from relatives of the patients in the case group were recruited and filled out the inventory. The State–Trait Anxiety Inventory (STAI) was used to measure anxiety. After selection of participants and neurological evaluation, all subjects were clinically interviewed at the outpatient clinic of neurology. Data were analyzed using SPSS software, version 16. Fisher's exact and chi-square tests were used for nominal variables, and the t-test was used for anxiety scores.ResultsThe average ages of the patients in the case and control groups were 28 and 27.5 years, respectively. State anxiety was significantly higher in patients with epilepsy than in the control group (p = 0.042). Also, a higher trait anxiety score was reported in the case group compared with the control group (p = 0.009).ConclusionThe rates of both state and trait anxiety were higher in patients in the case group. It appears that anxiety in epilepsy is not just a reaction to a stressful situation, and there may be genetic or temperamental factors that contribute to the relationship between epilepsy and anxiety.     

Consistent associations between measures of psychological stress and CMV antibody levels in a large occupational sample

Cytomegalovirus (CMV) is a herpes virus that has been implicated in biological aging and impaired health. Evidence, largely accrued from small-scale studies involving select populations, suggests that stress may promote non-clinical reactivation of this virus. However, absent is evidence from larger studies, which allow better statistical adjustment for confounding and mediating factors, in more representative samples.The present study involved a large occupational cohort (N = 887, mean age = 44, 88% male). Questionnaires assessed psychological (i.e., depression, anxiety, vital exhaustion, SF-12 mental health), demographic, socioeconomic (SES), and lifestyle variables. Plasma samples were analyzed for both the presence and level of CMV-specific IgG antibodies (CMV-IgG), used as markers for infection status and viral reactivation, respectively. Also assessed were potential biological mediators of stress-induced reactivation, such as inflammation (C-reactive protein) and HPA function (awakening and diurnal cortisol). Predictors of CMV infection and CMV-IgG among the infected individuals were analyzed using logistic and linear regression analyses, respectively.Confirming prior reports, lower SES (education and job status) was positively associated with infection status. Among those infected (N = 329), higher CMV-IgG were associated with increased anxiety (β = .14, p < .05), depression (β = .11, p = .06), vital exhaustion (β = .14, p < .05), and decreased SF-12 mental health (β = −.14, p < .05), adjusting for a range of potential confounders. Exploratory analyses showed that these associations were generally stronger in low SES individuals. We found no evidence that elevated inflammation or HPA-function mediated any of the associations.In the largest study to date, we established associations between CMV-IgG levels and multiple indicators of psychological stress. These results demonstrate the robustness of prior findings, and extend these to a general working population. We propose that stress-induced CMV replication warrants further research as a psychobiological mechanism linking stress, aging and health.     

Facial emotion recognition in psychiatrists and influences of their therapeutic identification on that ability

ObjectivesAlthough emotional cues like facial emotion expressions seem to be important in social interaction, there is no specific training about emotional cues for psychiatrists. Here, we aimed to investigate psychiatrists' ability of facial emotion recognition and relation with their clinical identification as psychotherapy–psychopharmacology oriented or being adult and childhood-adolescent psychiatrist.MethodsFacial Emotion Recognition Test was performed to 130 psychiatrists that were constructed by a set of photographs (happy, sad, fearful, angry, surprised, disgusted and neutral faces) from Ekman and Friesen's.ResultsPsychotherapy oriented adult psychiatrists were significantly better in recognizing sad facial emotion (p = .003) than psychopharmacologists while no significant differences were detected according to therapeutic orientation among child-adolescent psychiatrists (for each, p > .05). Adult psychiatrists were significantly better in recognizing fearful (p = .012) and disgusted (p = .003) facial emotions than child-adolescent psychiatrists while the latter were better in recognizing angry facial emotion (p = .008).ConclusionFor the first time, we have shown some differences on psychiatrists' facial emotion recognition ability according to therapeutic identification and being adult or child-adolescent psychiatrist. It would be valuable to investigate how these differences or training the ability of facial emotion recognition would affect the quality of patient–clinician interaction and treatment related outcomes.     

Trauma experience in children and adolescents: An assessment of the effects of trauma type and role of interpersonal proximity

The psychiatric sequelae associated with childhood experience(s) of trauma is complex and distinguishable from that of adult trauma exposure. Categories of impairment associated with experiences of early trauma include internalizing and externalizing emotional and behavioral problems, posttraumatic stress symptomatology, and dissociation. The present study assessed the relationship between the type of trauma experience (i.e., non-interpersonal or interpersonal) and the manifestation of a wide range of psychiatric symptomatology using prospective longitudinal data from a community sample of ethnically diverse children and adolescents (N = 1676; ages 4–18). The study also examined the relationship between different types of trauma experiences (e.g., direct, vicarious, interpersonal) and levels of various symptom domains (e.g., anxiety, posttraumatic stress, conduct problems). A number of factors relevant to the relationship between early trauma experience and subsequent impairment including temperament, socioeconomic status, sex, and age were included in the analyses. Results indicated that interpersonal traumas involving significant interpersonal proximity were associated with externalizing problems (i.e., oppositional defiant and conduct problems). Direct trauma experiences and emotionality were positively associated with almost all symptom domains. Implications for the relationship between trauma and developmental psychopathology are discussed.     

A hierarchical model for the relationships between general and specific vulnerability factors and symptom levels of generalized anxiety disorder

The present study examined a hierarchical model for the relationships between general and specific vulnerability factors and symptom manifestations of generalized anxiety disorder (GAD). A clinical sample of patients with GAD (N = 137) completed a set of self-report questionnaires for measuring neuroticism, extraversion, intolerance of uncertainty, metacognitive beliefs, and symptoms of generalized anxiety (i.e., worry) and depression. A bootstrapping analysis yielded support for a model in which the relation between the general vulnerability factor of neuroticism and symptoms of GAD were mediated by the specific vulnerability factors of intolerance of uncertainty and negative metacognitions. Implications for the classification and treatment of GAD are discussed.
