Obsessional thoughts and compulsive behaviors in a sample of women with postpartum mood symptoms

Postpartum psychiatric disorders are widely recognized by clinicians and researchers, yet while much attention has been paid to perinatal mood disorders, considerably less has been given to anxiety and obsessive–compulsive symptoms in this population. The present study examined anxiety and obsessive–compulsive symptoms among postpartum women with mood complaints, with the aim of delineating the relationship between these symptoms. Sixty postpartum women seeking treatment in a perinatal mood disorders clinic completed measures of depression, anxiety, and obsessive–compulsive symptoms. Obsession-like thoughts and compulsive-like (“neutralizing”) strategies were present among the majority of the sample, yet the severity of these symptoms ranged widely. Depressive and anxiety symptoms were associated with obsessive and neutralizing compulsive symptoms. It may be helpful to consider anxiety and depressive symptoms as part of a broad spectrum of perinatal psychiatric illness. Clinicians should assess for anxiety and obsessive–compulsive symptoms as routinely as they assess for depressive symptoms in the perinatal period.

The relationship between anxiety sensitivity and obsessive-compulsive symptom dimensions.

BACKGROUND AND OBJECTIVES Anxiety sensitivity (AS), the tendency to fear arousal-related body sensations based on beliefs that they are dangerous, is a cognitive vulnerability factor for certain anxiety symptoms such as panic and posttraumatic stress symptoms. Very little research, however, has examined the relationship between AS and obsessive-compulsive (OC) symptoms, which was the objective of the current research. METHODS We administered dimensional measures of AS and OC symptoms to a large sample of undergraduate students (N = 636). We also included measures of general distress and cognitive distortions related to OCD (i.e., obsessive beliefs) as control variables. RESULTS Regression analyses indicated that AS was predictive of OC symptoms even after controlling for general distress and obsessive beliefs. In addition, the three domains of AS (physical, social, and cognitive concerns) were differentially associated with the four dimensions of OC symptoms (contamination, responsibility for harm, symmetry, and unacceptable thoughts). LIMITATIONS Our findings are based on a non-clinical student sample and their generalization to OCD requires replication with a sample of OCD patients. CONCLUSIONS These results provide preliminary evidence that AS plays a role in OC symptoms. Implications for clinical practice and for future research are discussed.

Parenting and obsessive compulsive symptoms: Implications of authoritarian parenting

Cognitive behavioral theories of obsessive-compulsive disorder (OCD) have hypothesized a central role of social learning in the development of OCD. Research indicates that learning via key developmental relationships, such as parent–child interactions, may account for the emergence and maintenance of OC symptoms in adulthood. Baumrind identified three parental authority prototypes or styles, including permissive, authoritative, and authoritarian, that differ on the two dimensions of nurture and behavioral control. Permissive parents allow their children to do as they wish with little discipline, whereas authoritative parents implement reasonable guidelines while still providing a warm and nurturing environment. The third style, authoritarian, represents parenting that is rigid and values strict adherence to rules with lower levels of nurturing. To date, there has been no study examining these parenting styles and OCD symptomatology. The current investigation examined the relationships between parenting styles, obsessive-compulsive (OC) symptoms, and OC-related dysfunctional beliefs (i.e., “obsessive beliefs”) in a nonclinical sample (N = 227). Participants completed measures of these constructs, as well as a measure of general mood and anxiety symptoms. Results indicated that the authoritarian parenting style was significantly associated with both OC symptoms and OC beliefs (e.g., beliefs about the importance of thoughts and personal responsibility), even after controlling for general distress. Analyses also revealed that OC beliefs act as a partial mediator of the relationship between parenting style and OC symptoms. Findings are discussed in light of the implications for future research, particularly that pertaining to risk for OCD and the development of vulnerability factors.

Efficacy of a prevention program for postpartum obsessive–compulsive symptoms

Obsessive-Compulsive Disorder (OCD) has emerged as a common and impairing postpartum condition. Prospective studies have identified psychological vulnerabilities for the emergence of postpartum obsessive-compulsive symptoms (OCS), including general anxiety symptoms, pre-existing OCS, and specific cognitive distortions. The identification of these factors makes feasible the development of prevention programs that could reduce the impact of postpartum OCS. The present investigation examined a cognitive-behavioral prevention program using a randomized, double blind, controlled trial. Expecting mothers in their 2nd or 3rd trimester with an empirically established, malleable risk factor for postpartum OCS received either the prevention program (N=38) or a credible control program (N=33), both of which were incorporated into traditional childbirth education classes. Results revealed that at 1 month, 3 months, and 6 months postpartum, the prevention program was associated with significantly lower levels of obsessions and compulsions than was the control condition (all ps<0.05). Group differences remained significant even after controlling for baseline OCS and depression symptoms. Those in the prevention condition also reported decreasing levels of cognitive distortions, in contrast to the control condition (ps<0.05). Results support the potential utility of incorporating a CBT-based OCS prevention program into childbirth education classes.

Do Cognitive Reappraisal and Diaphragmatic Breathing Augment Interoceptive Exposure for Anxiety Sensitivity

Interoceptive exposure (IE) is an effective procedure for reducing anxiety sensitivity (AS) and the symptoms of panic disorder. However, considerable variance exists in how IE is delivered among clinicians, and the extent to which IE is enhanced by the concurrent use of cognitive reappraisal (CR) and diaphragmatic breathing (DB) is unclear. Participants (N = 58) with high AS were randomly assigned to one of four single-session interventions: (a) IE only, (b) IE 1 CR, (c) IE 1 CR 1 DB, or (d) expressive writing control. IE was superior to expressive writing in reducing AS and associated anxiety symptoms. The addition of CR and DB did not enhance the benefits of IE at either posttreatment or 1-week follow-up. These findings highlight the specific efficacy of IE in reducing AS and call into question the common practice of combining IE with cognitive and breathing strategies. Theoretical and clinical implications are discussed.

The contribution of experiential avoidance and social cognitions in the prediction of social anxiety.

BACKGROUND Cognitive models propose that social anxiety arises from specific dysfunctional cognitions about the likelihood and severity of embarrassment. Relational frame theory (RFT), on the other hand, posits that social anxiety arises from the unwillingness to endure unpleasant internal experiences (i.e. experiential avoidance [EA]). Although cognitive models have garnered empirical support, it may be that newer models such as RFT can improve our ability to predict and treat social anxiety. AIMS We aimed to elucidate the relationship between dysfunctional cognitions and EA, as well as their independent and relative contributions to the prediction of social anxiety symptoms. We hypothesized that dysfunctional cognitions and EA would each be associated with social anxiety, as well as with each other. We also predicted that both EA and dysfunctional cognitions would remain independent predictors of social anxiety symptoms after controlling for each other and general distress. METHOD Undergraduates high (n = 173) and low (n = 233) in social anxiety completed measures of social anxiety, dysfunctional cognitions, EA, and general distress. The overall sample was 66.3% female; mean age = 20.01 years (SD = 2.06). RESULTS Correlational analyses revealed that EA, dysfunctional cognitions, and social anxiety symptoms were moderately correlated with one another. Additionally, hierarchical regression analyses revealed that dysfunctional cognitions predicted social anxiety symptoms even after controlling for EA; the reverse was not found. CONCLUSIONS RESULTS suggest that EA and social anxiety specific cognitive distortions overlap to a moderate extent. EA does not add to the prediction of social anxiety symptoms above and beyond dysfunctional cognitions. Additional theoretical and treatment implications of the results are discussed.

Internalized HIV Stigma and Mindfulness Associations With PTSD Symptom Severity in Trauma-Exposed Adults With HIV/AIDS

Rates of both traumatic event exposure and posttraumatic stress disorder (PTSD; 22%-54%) are disproportionately elevated among people living with HIV/AIDS (PLHA). Trauma and related psychopathology significantly affect quality of life and disease management in this patient population. The current study examined associations between internalized HIV stigma, mindfulness skills, and the severity of PTSD symptoms in trauma-exposed PLHA. Participants included 137 PLHA (14.6% female; Mage = 48.94, SD = 8.89) who reported experiencing on average, five (SD = 2.67) traumatic events; 34% met diagnostic criteria for PTSD. Results indicate that after controlling for sex, age, education, and number of traumatic events, internalized HIV stigma was positively related to overall PTSD symptom severity (β = .16, p < .05) and severity of re-experiencing (β = .19, p < .05) and hyper-arousal (β = .16, p = .05), but not avoidance, PTSD symptom clusters. Among the mindfulness facets measured, acting with awareness was uniquely negatively related to the overall severity of PTSD symptoms (β = − .25, p < .01) and the severity of re-experiencing (β = − .25, p < .05), avoidance (β = − .25, p < .05), and hyper-arousal (β = − .29, p < .01) PTSD symptom clusters. These effects were observed after accounting for covariates and shared variance with other mindfulness facets. Theoretically, the present findings suggest that internalized HIV stigma may serve as a vulnerability factor for the severity of certain PTSD symptoms, whereas acting with awareness may function as a protective or resiliency factor for the severity of PTSD symptoms. Implications for the treatment of trauma-exposed PLHA are discussed.

Anxiety sensitivity mediates the association between post-traumatic stress symptom severity and interoceptive threat-related smoking abstinence expectancies among World Trade Center disaster-exposed smokers.

INTRODUCTION Anxiety sensitivity (fear of internal anxiety-relevant bodily sensations) is an individual difference variable that is associated with the development and maintenance of posttraumatic stress disorder (PTSD) and is also involved in the maintenance/relapse of smoking. Abstinence expectancies are crucial to smoking maintenance, yet, past work has not explored how PTSD symptom severity and anxiety sensitivity contribute to them. METHOD Participants were 122 treatment-seeking daily smokers (36.1% female; Mage=49.2, SD=9.7; cigarettes per day: M=18.3, SD=15.2) who were exposed to the World Trade Center disaster on September 11, 2001 and responded to an advertisement for a clinical smoking cessation trial. The indirect effect of anxiety sensitivity was tested in terms of the effect of PTSD symptom severity on smoking abstinence expectancies (i.e., anxiety sensitivity as a statistical mediator). RESULTS PTSD symptom severity was positively associated with interoceptive threat-related smoking abstinence expectancies: expecting harmful consequences (β=.33, p<.001) and somatic symptoms (β=.26, p=.007). PTSD symptom severity was also significantly associated with anxiety sensitivity (β=.27, p=.003). Anxiety sensitivity mediated the association between PTSD symptom severity and expectancies about the harmful consequences (β=.09, CI95%=.02-.21; ΔR(2)=.076) and somatic symptoms (β=.11, CI95%=.02-.24; ΔR(2)=.123) from smoking abstinence, with medium effect sizes (Κ(2)=.08 and .10, respectively). CONCLUSIONS These data document the role of PTSD symptoms in threat-based expectancies about smoking abstinence and suggest anxiety sensitivity may underlie the associations between PTSD symptom severity and abstinence expectancies.

Smoking to Regulate Negative Affect: Disentangling the Relationship Between Posttraumatic Stress and Emotional Disorder Symptoms, Nicotine Dependence, and Cessation-Related Problems

INTRODUCTION Posttraumatic stress disorder (PTSD) is associated with various aspects of cigarette smoking, including higher levels of nicotine dependence and cessation difficulties. Affect-regulatory smoking motives are thought to, in part, underlie the association between emotional disorders such as PTSD and smoking maintenance, although few studies have empirically tested this possibility. METHODS Data were analyzed from 135 treatment-seeking smokers who were directly exposed to the World Trade Center disaster on September 11, 2001. We modeled the direct effect of 9/11 PTSD symptom severity on nicotine dependence, perceived barriers to smoking cessation, and severity of problematic symptoms experienced during prior cessation attempts. We also examined the indirect effect of PTSD on these outcomes via negative affect reduction smoking motives. Parallel models were constructed for additional emotional disorder symptoms, including panic and depressive symptoms. RESULTS PTSD symptom severity was associated with nicotine dependence and perceived barriers to cessation, but not problems during prior quit attempts indirectly via negative affect reduction smoking motives. Panic and depressive symptoms both had significant indirect effects, via negative affect reduction smoking motives, on all three criterion variables. CONCLUSIONS Affect-regulatory smoking motives appear to underlie associations between the symptoms of emotional disorders such as PTSD, panic, and depression in terms of smoking dependence and certain cessation-related criterion variables. IMPLICATIONS Overall, this investigation suggests negative affect reduction smoking motives help to explain the relationship of PTSD, depression, and panic symptoms to nicotine dependence, severity of problems experienced during prior quit attempts and perceived barriers to cessation. These results highlight the importance of assessing motivations for smoking in the context of cessation treatment, especially among those with emotional disorder symptoms. Future interventions might seek to utilize motivational interviewing and cognitive restructuring techniques to address coping-oriented motives for smoking, in addition to skills for managing negative affect, as a means of improving quit outcomes.

Clinical and personality traits in emotional disorders: Evidence of a common framework.

Certain clinical traits (e.g., ruminative response style, self-criticism, perfectionism, anxiety sensitivity, fear of negative evaluation, and thought suppression) increase the risk for and chronicity of emotional disorders. Similar to traditional personality traits, they are considered dispositional and typically show high temporal stability. Because the personality and clinical-traits literatures evolved largely independently, connections between them are not fully understood. We sought to map the interface between a widely studied set of clinical and personality traits. Two samples (N = 385 undergraduates; N = 188 psychiatric outpatients) completed measures of personality traits, clinical traits, and an interview-based assessment of emotional-disorder symptoms. First, the joint factor structure of these traits was examined in each sample. Second, structural equation modeling was used to clarify the effects of clinical traits in the prediction of clinical symptoms beyond negative temperament. Third, the incremental validity of clinical traits beyond a more comprehensive set of higher-order and lower-order personality traits was examined using hierarchical regression. Clinical and personality traits were highly correlated and jointly defined a 3-factor structure-Negative Temperament, Positive Temperament, and Disinhibition-in both samples, with all clinical traits loading on the Negative Temperament factor. Clinical traits showed modest but significant incremental validity in explaining symptoms after accounting for personality traits. These data indicate that clinical traits relevant to emotional disorders fit well within the traditional personality framework and offer some unique contributions to the prediction of psychopathology, but it is important to distinguish their effects from negative temperament/neuroticism.
