Are expressive suppression and cognitive reappraisal associated with stress-related symptoms?

Emotion dysregulation is thought to be critical to the development of negative psychological outcomes. Gross (1998b) conceptualized the timing of regulation strategies as key to this relationship, with response-focused strategies, such as expressive suppression, as less effective and more detrimental compared to antecedent-focused ones, such as cognitive reappraisal. In the current study, we examined the relationship between reappraisal and expressive suppression and measures of psychopathology, particularly for stress-related reactions, in both undergraduate and trauma-exposed community samples of women. Generally, expressive suppression was associated with higher, and reappraisal with lower, self-reported stress-related symptoms. In particular, expressive suppression was associated with PTSD, anxiety, and depression symptoms in the trauma-exposed community sample, with rumination partially mediating this association. Finally, based on factor analysis, expressive suppression and cognitive reappraisal appear to be independent constructs. Overall, expressive suppression, much more so than cognitive reappraisal, may play an important role in the experience of stress-related symptoms. Further, given their independence, there are potentially relevant clinical implications, as interventions that shift one of these emotion regulation strategies may not lead to changes in the other.

Overgeneral Autobiographical Memory and Traumatic Events: An Evaluative Review.

Does trauma exposure impair retrieval of autobiographical memories? Many theorists have suggested that the reduced ability to access specific memories of life events, termed overgenerality, is a protective mechanism helping attenuate painful emotions associated with trauma. The authors addressed this question by reviewing 24 studies that assessed trauma exposure and overgenerality, examining samples with posttraumatic stress disorder, acute stress disorder, depression, traumatic event exposure, and other clinical disorders. Limitations are discussed, including variations in assessment of events, depression, and overgenerality and the need for additional comparison groups. Across studies, there was no consistent association between trauma exposure and overgenerality, suggesting that trauma exposure is unlikely to be the primary mechanism leading to overgenerality. Instead, psychopathology factors such as depression and posttraumatic stress appear to be more consistently associated with overgenerality. Alternative overgenerality theories may help identify key overgenerality mechanisms, improving current understanding of autobiographical memory processes underlying psychopathology.

Symptoms of posttraumatic stress predict craving among alcohol treatment seekers: results of a daily monitoring study.

Alcohol use disorders (AUDs) and Posttraumatic Stress Disorder (PTSD) commonly co-occur. Craving for alcohol is a common aspect of AUD, with and without PTSD, and is one of the key predictors of continued problematic alcohol use among treatment seekers. The present study sought to investigate the self-medication hypothesis using daily Interactive Voice Response (IVR) reports to examine the relationships between PTSD symptomatology and both same-day and next-day alcohol craving. Twenty-nine individuals with an AUD (26 of whom screened positive for PTSD) entering AUD treatment provided daily IVR data for up to 28 days regarding their alcohol use, craving, and 7 symptoms of PTSD. Given the nested nature of daily data, generalized estimating equations using a negative binomial distribution and a log link function were used to test hypotheses. Results suggest that days with greater overall PTSD severity are associated with greater alcohol craving, and greater reports of startle and anger/irritability were particularly associated with same-day craving. The next-day results suggest that the combination of the 7 PTSD symptoms did not predict next-day craving. However, greater distress from nightmares the previous night, emotional numbing, and hypervigilance predicted greater next-day craving, while greater anger/irritability predicted lower next-day craving. These findings highlight the importance of assessing the relationship between specific symptoms of PTSD and alcohol cravings in order to increase our understanding of the functional interplay among them for theory building. Additionally, clinicians may be better able to refine treatment decisions to more efficiently break the cycle between PTSD-related distress and AUD symptoms.

Impact of emotional approach coping and hope on PTSD and depression symptoms in a trauma exposed sample of Veterans receiving outpatient VA mental health care services

Abstract The present investigation evaluates the relationship between coping style, dispositional hope, and posttraumatic stress disorder (PTSD) and depression symptom severity in a trauma-exposed Veteran sample. Specifically, we evaluated the adaptive value of emotional avoidant and approach coping strategies and perceptions of hope in a sample of 209 trauma-exposed Veterans receiving outpatient mental health care at a VA facility. Participants completed a life events questionnaire and inventories assessing coping, dispositional hope, and PTSD and depression symptom severity. Hierarchical regression analyses were conducted controlling for relevant demographic variables. Greater levels of emotional avoidance and lower levels of emotional expression were significantly associated with increased PTSD and depression symptom severity. Dispositional hope was positively associated with depression symptoms only and perceptions of hope moderated the association between emotional avoidance coping and depression symptoms. Findings highlight the value of emotional coping strategies and perceptions of hope in posttraumatic adjustment. Specifically, employing coping techniques that encourage emotional expression may promote improved adjustment among trauma-exposed individuals, while reduced perceptions of hope and the use of avoidant coping strategies may place individuals at greater risk for depression following exposure to traumatic events.

The correspondence of daily and retrospective PTSD reports among female victims of sexual assault.

Research addressing the association between daily and retrospective symptom reports suggests that retrospective reports are typically inflated. The present study examined the association between daily posttraumatic stress disorder (PTSD) symptom reports over 1 month and a corresponding retrospective report (PTSD Checklist [PCL]; Weathers et al., 1993) for both total scores and symptom clusters. The authors hypothesized that greater PTSD symptom instability and greater depression would be associated with poorer agreement between daily and retrospective reports. Data were collected from 132 female college students who were sexually assaulted. Multilevel modeling indicated very strong agreement between mean daily and retrospective reports for total scores and symptom clusters, with pseudo-R2 ranging from .55 to .77. Depression symptoms did not moderate this association, but daily-retrospective agreement was lowest for the avoidance cluster, which was also the most unstable. Finally, retrospective recall for each symptom cluster showed acceptable specificity to the corresponding daily symptom clusters. Overall, these findings suggest that retrospective memories for global PTSD symptoms and symptom clusters, as assessed by the PCL, are consistent with daily reports over a 1-month period. Implications for clinical assessment methodology are discussed.

Alcohol Use, Problems, and the Course of Posttraumatic Stress Disorder: A Prospective Study of Female Crime Victims

Objective: In this study the authors examine whether alcohol use disorder status and consequences of drinking moderate the course of posttraumatic stress disorder (PTSD) over the first 6 months following trauma exposure in a sample of female victims of interpersonal violence. Methods: Female sexual and physical assault victims (N = 64) were recruited through police, hospital, and victim service agencies. Women completed structured clinical interviews and self-report measures within the first 5 weeks, 3 months, and 6 months post-trauma with 73% retention across all three time points (n = 47). Analyses were conducted using Hierarchical Linear Modeling using alcohol abuse/dependence, peak alcohol use, and consequences during the 30 days prior to assault as moderators of the course of PTSD over time. Results: Women with alcohol use disorder at baseline had lower initial PTSD symptoms but also less symptom recovery over time than women without alcohol use disorder. This pattern of results was also found for those with high negative drinking consequences during the month prior to the assault. Baseline alcohol use was not found to significantly moderate PTSD course over the 6 months. Conclusions: Findings suggest that negative consequences associated with alcohol use may be a risk factor for PTSD. Incorporating assessment of drinking problems for women presenting early post-trauma may be useful for identifying PTSD risk.

Comparing the diagnosis of PTSD when assessing worst versus multiple traumatic events in a chronically mentally ill sample.

Despite interest in the nature of the traumatic event required to meet Criterion A for posttraumatic stress disorder (PTSD) as defined in the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV; American Psychiatric Association, 1994), little attention has been paid to the diagnostic ramifications of linking PTSD symptoms to a single traumatic event in the context of multiple trauma exposures. In this study, 67 dually diagnosed clients with at least 2 potential Criterion A traumatic events completed the Posttraumatic Stress Diagnostic Scale twice, in counterbalanced order: once regarding their worst event and once regarding all events. When responding regarding their worst trauma, 53.7% met probable PTSD criteria. This rose to 67.2% when considering all traumas. Although preliminary, these results suggest that linking PTSD symptoms to a single traumatic event excludes a meaningful number of cases who are otherwise indistinguishable based on symptom profile.

Blocking for Sequential Political Experiments.

In typical political experiments, researchers randomize a set of households, precincts, or individuals to treatments all at once, and characteristics of all units are known at the time of randomization. However, in many other experiments, subjects “trickle in” to be randomized to treatment conditions, usually via complete randomization. To take advantage of the rich background data that researchers often have (but underutilize) in these experiments, we develop methods that use continuous covariates to assign treatments sequentially. We build on biased coin and minimization procedures for discrete covariates and demonstrate that our methods outperform complete randomization, producing better covariate balance in simulated data. We then describe how we selected and deployed a sequential blocking method in a clinical trial and demonstrate the advantages of our having done so. Further, we show how that method would have performed in two larger sequential political trials. Finally, we compare causal effect estimates from differences in means, augmented inverse propensity weighted estimators, and randomization test inversion.

Psychometric evaluation of the Overall Anxiety Severity And Impairment Scale (OASIS) in individuals seeking outpatient specialty treatment for anxiety-related disorders

BACKGROUND Comorbidity among anxiety-related diagnoses is common, highlighting the need for brief, meaningful measures of anxiety that cut across diagnoses. METHODS The current study examined the psychometric properties of one such measure, the Overall Anxiety Severity and Impairment Scale (OASIS) (Norman et al., 2006), in a naturalistic sample of individuals seeking treatment at an outpatient anxiety treatment center. We examined the measure׳s structure, convergent validity, and potential effects of respondent gender. Using ROC analysis, we estimated an optimal cut-score for determining presence of an anxiety disorder in this sample. Finally, we examined the responsiveness of the OASIS to clinical change and calculated a reliable change index. RESULTS We found strong psychometric properties of the OASIS. A unitary factor structure with correlated residuals on the first two items provided the best fit to the data. A cut-score of eight best distinguished the presence of an anxiety-related diagnosis. In measurement invariance analyses, we found evidence that men and women respond similarly to the measure. In addition, we found that change in the OASIS was correlated with change in other measures, and we estimated that a four-point change in the OASIS can be considered clinically reliable. LIMITATIONS Sample characteristics may limit generalizability. Diagnoses were established by clinicians using a semi-structured interview that, while based upon DSM-IV diagnostic criteria, has not been psychometrically evaluated. CONCLUSION The results provide support for the use of the OASIS in specialty treatment for anxiety-related diagnoses and further highlight the strengths of this measure in clinical practice and research settings.

The Effects of Expressive and Experiential Suppression on Memory Accuracy and Memory Distortion in Women with and Without PTSD

Specific emotion regulation strategies impinge on cognitive resources, impairing memory accuracy; however, their effects on memory distortion have been largely unexamined. Further, little is known about the effects of emotion regulation on memory in individuals with posttraumatic stress disorder (PTSD), who exhibit both emotion regulation and memory difficulties. We examined the effects of expressive suppression (i.e., concealing visible signs of emotion), experiential suppression (i.e., suppressing the subjective emotional experience), and control instructions on memory accuracy and distortion in traumaexposed individuals with PTSD, those without PTSD, and psychologically healthy controls. Expressive and, to a lesser degree, experiential suppression led to poorer memory accuracy and both expressive and experiential suppression led to less memory distortion compared to control instructions. Participants with and without PTSD did not significantly differ. Under high cognitive load, irrelevant details may receive more processing, potentially leading to lower accuracy but improved processing of source information, preventing memory distortion.
