The past decade witnessed considerable debate over the factor structure of the Anxiety Sensitivity Index (ASI), with an eventual consensus emerging that supported a hierarchically organized factor structure. The present study attempted to replicate and examine the overall stability and utility of the hierarchical ASI factor pattern using a large sample of outpatients participating in an ongoing longitudinal study of anxiety disorders. Results supported a hierarchical factor structure for the ASI consisting of three lower-order factors measuring physical concerns, mental incapacitation concerns, and social concerns, all of which loaded significantly on a single second-order factor. Correlational analyses show good test-retest reliability and consistent patterns of intercorrelation for these factor-derived subscales across a 10-month time frame. Additional analyses provide support for the discriminant validity of the ASI subscales with regard to individuals with specific anxiety disorders. The theoretical implications of these findings for future evaluations of anxiety sensitivity are discussed.
This study contrasted the effects of intimate partner and nonpartner sexual assault on women's 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.
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 measure's 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.
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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
