Self-Focused Attention and Social Anxiety in Social Phobics and Normal Controls

Self-focused attention has been demonstrated to influence and be influenced by situational social anxiety in clients with social phobia, but the mechanisms of this relationship have yet to be established. This study examines the degree to which self-focus exacerbates anxiety and impairs social performance in normal controls as well as social phobics. In addition, the role of fear of negative evaluation as a moderator of this relationship is examined. Results supported the hypothesis of a functional role of self-focused attention in anxiety but not social performance, and this relationship held true for participants in the normal control group as well as the social phobia group. Fear of negative evaluation was surprisingly not a factor in this relationship. These results are discussed in a framework of shifting attributions for social effectiveness based on the shift in perspective engendered by self-focused attention.

Emotional deficits in military‐related PTSD: An investigation of content and process disturbances

To expound on the nature of emotional deficits in PTSD, the current study investigated the relationships among emotion content and process variables and PTSD symptomatology in a sample of 85 veterans with military-related trauma. Alexithymic externally oriented thinking and negative affectivity emerged as the most consistent predictors of PTSD symptoms; however, depression was the only variable associated with emotional numbing. Theoretical and clinical implications of these findings are discussed, as well as future research directions including the collateral and clinician assessment of emotional functioning, use of other process measures, and inclusion of various control groups.

Differing Effects of Partner and Nonpartner Sexual Assault on Women's Mental Health:

This study contrasted the effects of intimate partner and nonpartner sexual assault on womens mental health among a sample (N = 835) of low-income, ethnically diverse community women. Compared to sexual assault by a previous partner or by a non-intimate partner, sexual assault by a current partner was the strongest predictor of PTSD, stress, and dissociation. Non–intimate partner sexual assault was only a significant predictor of PTSD and only for African American women. These findings suggest that the victim-offender relationship is important when considering the impact of sexual assault. Specifically, sexual assault perpetrated by an intimate partner may be especially traumatic.

Confirmatory factor and measurement invariance analyses of the emotion regulation questionnaire

Emotion regulation is widely studied in many areas of psychology and the number of publications on emotion regulation has increased exponentially over the past few decades. Additionally, interest in the relationships between emotion dysregulation processes and psychopathology has drastically increased in recent years. The Emotion Regulation Questionnaire (ERQ) was developed to measure two specific constructs related to emotion control: reappraisal and suppression (Gross & John, 2003). In its initial validation study and subsequent analyses, the instrument was shown to possess sound psychometric properties, but, to date, inquiry regarding the measures characteristics has been limited. Factor analytic examinations of commonly used instruments are recommended to validate the properties of a given measure and increase researchers understanding of the measured constructs. The current study examined the psychometric properties of the ERQ in a sample of 1,188 undergraduates through confirmatory factor analysis. Additionally, tests of measurement invariance were employed in order to examine potential structural differences based on gender and ethnicity. The current study supported the original structure of the measure with all demographic groups and exceptional fit was demonstrated. Additional normative data for gender and ethnic groups are included. Results support the use of the instrument in future research.

Characteristics and predictors of full and partial recovery from generalized anxiety disorder in primary care patients.

The current study examined the naturalistic course of generalized anxiety disorder (GAD) in a sample of 113 primary care patients across a 2-year period. Initial diagnoses were established using structured clinical interviews according to DSM-IV diagnostic criteria. Results indicated that the majority of patients meeting DSM-IV diagnostic criteria for GAD were still symptomatic to some degree after 2 years of follow-up. Rates of full and partial recovery from GAD, however, were found to be higher than those reported for previous studies of GAD in psychiatric patients. Diagnostic comorbidity, severity of psychosocial impairment, and gender were found to be significantly associated with achieving full or partial recovery from GAD. Psychiatric treatment was not found to be associated with time to full or partial recovery from GAD symptoms, likely due to a treatment-biasing effect. These results underscore that GAD is a chronic and persistent illness in primary care patients.

A factor analytic comparison of five models of PTSD symptoms

This study examined the factor structure of PTSD symptoms in a sample of college students (n=344) reporting exposure to a range of traumatic events. The sample was randomly split and an exploratory factor analysis was conducted with half of the sample. The factor structure obtained in the exploratory analysis was evaluated against three other models using confirmatory factor analysis utilizing the second half of the sample. This series of factor analyses identified and confirmed a three-factor symptom structure consisting of intrusion/avoidance, dysphoria, and hyperarousal clusters. These results add to the body of literature which has found that PTSD includes a cluster of symptoms shared with other diagnoses (dysphoria) and a more specific factor related directly to the effects of encountering traumatic experiences.

An examination of the differential effects of the experience of DSM-IV defined traumatic events and life stressors.

Recent evidence suggests that individuals exposed to traumatic events report similar, if not lower, levels of posttraumatic stress disorder (PTSD) symptoms than individuals exposed to nontraumatic stressful life events [J. Anxiety Disord. 19 (2005) 687-698; Br. J. Psychiatry 186 (2005) 494-499]. The current study compared the level of self-reported PTSD symptoms in a large sample (n=668) of trauma and nontrauma exposed college students. Participants were assessed for past trauma history as well as current symptoms of PTSD, depression, social interaction anxiety, and current positive and negative affect. Results indicated that while those who had experienced a traumatic event reported statistically significantly higher levels of PTSD symptoms, these differences were no longer clinically significant after other psychological distress factors were accounted for. Additional analyses suggested that those who had experienced events of an interpersonal nature had significantly higher levels of PTSD symptoms than those who had experienced other types of events.

Path analytic examination of a cognitive model of PTSD

Ehlers and Clark (2000) developed a cognitive model of posttraumatic stress disorder (PTSD) symptom maintenance which implicated the role of posttraumatic cognitions and aspects of the trauma memory in maintaining symptoms via an increased sense of current threat. The aim of the current study was to empirically test a variant of this model using path analysis. Participants in the current study were 514 undergraduates at a midwestern university who reported experiencing at least one traumatic event. Path analyses examined various models of the possible relationships between ones posttraumatic cognitions and the centrality of the traumatic event to the sense of self (considered an aspect of memory integration) in predicting current level of PTSD symptoms. Results indicate that both event centrality and posttraumatic cognitions are unique and independent predictors of current symptom level. Overall, the results of this study support aspects of Ehlers and Clarks cognitive model of PTSD; cognitive appraisals of the self and centrality of the event were highly related to levels of distress. However, the current study suggests that overly integrated trauma memories may lead to greater distress and not poorly integrated ones as suggested by Ehlers and Clark.

Psychometric properties of the Liebowitz Social Anxiety Scale (LSAS) in a longitudinal study of African Americans with anxiety disorders

The Liebowitz Social Anxiety Scale (LSAS) is a widely used measure of social anxiety. However, no study has examined the psychometric properties of the LSAS in an African American sample. The current study examined the LSAS characteristics in 97 African Americans diagnosed with an anxiety disorder. Overall, the original LSAS subscales showed excellent internal consistency and temporal stability. Similar to previous reports, fear and avoidance subscales were so highly correlated that they yielded redundant information. Confirmatory factor analyses for three previously proposed models failed to demonstrate an excellent fit to our data. However, a four-factor model showed minimally acceptable fit. Overall, the LSAS performed similarly in our African American sample as in previous European American samples. Exploratory factor analyses are warranted to determine whether a better factor structure exists for African Americans.

Attachment and affective resolution following a stressful event: General and religious coping as possible mediators

The current study replicated and extended previous research on mediators of attachment qualities and outcome (affective resolution), including appraisal, coping, and religious coping. Structural equation models were used to analyze the responses on an Internet survey for a primarily Christian sample of 1,289 adults (416 men and 873 women). As expected, appraisal was a significant mediator of ambivalent attachment qualities and coping, as well as ambivalent attachment qualities and religious coping. Avoidance coping significantly mediated ambivalent attachment qualities and affective resolution; it also mediated avoidant attachment qualities and affective resolution. Fit indices for models were adequate only when differences between interpersonal and non-interpersonal events were taken into account. Substantial similarities were found in the relationships among variables for the two models examined, one including coping in general and the other including religious coping. Religious coping provided additional explanatory value to more secular models of coping in a highly religious sample. The implications for assimilating religious coping into mainstream coping research are discussed.
