factor structure of the tonic Immobility scale in female sexual assault survivors an exploratory and confirmatory factor analysis
Journal of Anxiety Disorders, 2007Co-Authors: Tiffany Fuse, Gordon G. Gallup, Brian P Marx, John P Forsyth, Scott R WeaverAbstract:Tonic Immobility (TI) is an involuntary component of the fear response that is characterized by freezing or Immobility in situations involving extreme fear coupled with physical restraint. The present investigation evaluated the factor structure of the Tonic Immobility Scale (TIS; Forsyth, J. P., Marx, B., Fuse, T. M. K., Heidt, J., & Gallup, G. G., Jr. (2000). The Tonic Immobility Scale. Albany, NY: Authors)--a newly developed measure to assess components of TI in female sexual assault survivors. Study 1 (N=88) consisted of an Exploratory Factor Analysis of sexual assault survivors' responses on the TIS, whereas Study 2 (N=191) involved a Confirmatory Factor Analysis (CFA) with a second independent sample of female sexual assault survivors. Findings from both studies suggest that the TIS is comprised of two independent factors: physical Immobility and fear. Findings are discussed in terms of the theoretical and practical implications of the factor solution obtained, particularly with regard to evaluating TI in adult survivors of sexual assault.

tonic Immobility mediates the influence of peritraumatic fear and perceived inescapability on posttraumatic stress symptom severity among sexual assault survivors
Journal of Traumatic Stress, 2008Co-Authors: Michelle J Bovin, Shari Jagerhyman, Sari D Gold, Brian P Marx, Denise M SloanAbstract:This study evaluated whether tonic Immobility mediates the relations between perceived inescapability, peritraumatic fear, and posttraumatic stress disorder (PTSD) symptom severity among sexual assault survivors. Female undergraduates (N = 176) completed questionnaires assessing assault history, perceived inescapability, peritraumatic fear, tonic Immobility, and PTSD symptoms. Results indicated that tonic Immobility fully mediated relations between perceived inescapability and overall PTSD symptom severity, as well as reexperiencing and avoidance/numbing symptom clusters. Tonic Immobility also fully mediated the relation between fear and reexperiencing symptoms, and partially mediated relations between fear and overall PTSD symptom severity, and avoidance/numbing symptoms. Results suggest that tonic Immobility could be one path through which trauma survivors develop PTSD symptoms. Further study of tonic Immobility may inform our ability to treat trauma victims.

Incidence of Vocal Fold Immobility in Patients with Dysphagia
Dysphagia, 2005Co-Authors: Steven B. Leder, Douglas A. RossAbstract:This study prospectively investigated the incidence of vocal fold Immobility, unilateral and bilateral, and its influence on aspiration status in a referred population of 1452 patients for a dysphagia evaluation from a large, urban, tertiary-care, teaching hospital. Main outcome measures included overall incidence of vocal fold Immobility and aspiration status, with specific emphasis on age, etiology, and side of vocal fold Immobility, i.e., right, left, or bilateral. Overall incidence of vocal fold Immobility was 5.6% (81 of 1452 patients), including 47 males (mean age 55.7 yr) and 34 females (mean age 59.7 yr). In the subgroup of patients with vocal fold Immobility, 31% (25 of 81) exhibited unilateral right, 60% (49 of 81) unilateral left, and 9% (7 of 81) bilateral impairment. Overall incidence of aspiration was found to be 29% (426 of 1452) of all patients referred for a swallow evaluation. Aspiration was observed in 44% (36 of 81) of patients presenting with vocal fold Immobility, i.e., 44% (11 of 25) unilateral right, 43% (21 of 49) unilateral left, and 57% (4 of 7) bilateral vocal fold Immobility. Left vocal fold Immobility occurred most frequently due to surgical trauma. A liquid bolus was aspirated more often than a puree bolus. Side of vocal fold Immobility and age were not factors that increased incidence of aspiration. In conclusion, vocal fold Immobility, with an incidence of 5.6%, is not an uncommon finding in patients referred for a dysphagia evaluation in the acute-care setting, and vocal fold Immobility, when present, was associated with a 15% increased incidence of aspiration when compared with a population already being evaluated for dysphagia.
