Predictors of tonic immobility during traumatic events

چکیده
Título: Predictores de la inmovilidad tónica ante eventos traumáticos. Resumen: La inmovilidad tónica (IT) es una posible reacción ante el peligro que es facilitada por el miedo intenso, la restricción física y la incapacidad percibida de escapar. Otras variables que podrían influir, tales como el tipo de eventos traumáticos, características de los mismos y características personales han sido poco o nada estudiadas. El presente estudio evaluó la capacidad de estas variables para predecir la IT en una muestra de 273 universitarios que habían experimentado al menos un suceso traumático. El 7.7% y el 13.2% de participantes reaccionaron con IT según las dos definiciones más estrictas adoptadas. La mayoría de las variables estuvieron significativamente asociadas con la IT en análisis univariantes. Sin embargo, en un análisis de regresión múltiple, sólo ciertas características de los eventos (ocurrencia de maltrato físico/ abuso sexual, número de tipos diferentes de eventos experimentados) y determinadas reacciones ante los mismos (percepción de lo traumáticos que fueron, respuesta de miedo intenso) fueron predictores significativos de la IT. Puesto que estos predictores sólo explicaron el 25% de la varianza, debería investigarse la influencia de otras variables, tales como el neuroticismo, la afectividad negativa y la sensación de falta de control personal o de recursos para afrontar los eventos traumáticos. Palabras clave: inmovilidad tónica; eventos traumáticos; trauma; Escala de Inmovilidad Tónica; Cuestionario de Eventos Traumáticos. Abstract: Tonic immobility (TI) is a possible reaction to danger that is facilitated by intense fear, physical restraint and perceived inability to escape. Other variables that could affect TI, such as the type and characteristics of traumatic events and personal characteristics have been little or no studied. The present study evaluated the power of these variables to predict TI in a sample of 273 college students who had experienced at least one traumatic event. Of the sample, 7.7% and 13.2% responded with TI according to the two stricter definitions adopted. Most of the variables were significantly associated with TI in univariate analyses. However, in a multiple regression analysis, only certain features of the events (occurrence of physical/sexual abuse, number of different types of events experienced) and certain reactions to them (perception of how traumatic were the events, severe fear response) were significant predictors of TI. Since these predictors explained only 25% of the variance, the influence of other variables –such as neuroticism, negative affectivity and perceived lack of personal control or resources to cope with traumatic events– should be investigated.

Is there tonic immobility in humans? Biological evidence from victims of traumatic stress.
Tonic immobility, characterized by profound motor inhibition, is elicited under inescapable threat in many species. To fully support the existence of tonic immobility in humans, our aim was to elicit this reaction in a laboratory setting and measure it objectively. To mimic exposure to life-threatening events in the lab, trauma-exposed participants with PTSD (n=18) and without PTSD (n=15) liste...

Tonic immobility is a basic defense strategy which has not been studied in depth in humans. Data suggest that it may be a relatively frequent phenomenon in victims of rape and sexual abuse, but its occurrence has not been systematically explored in other types of trauma. We carried out a retrospective study in a sample of 100 university students to establish whether tonic immobility varies depe...

Tonic immobility is an involuntary, last-ditch defensive reaction characterized by physical inactivity in a context of inescapable threat that has been described in many species, including humans. The occurrence of this defensive response is a predictor of the severity of psychiatric disorders and may be considered as an index of an intense reaction to a traumatic event. Here, we investigated w...

OBJECTIVE Peritraumatic reactions feature prominently among the main predictors for development of posttraumatic stress disorder (PTSD).

Our objective ...

Patients with posttraumatic stress disorder (PTSD) reporting peritraumatic tonic immobility show the most severe symptoms and a poorer response to treatment. This study investigated the predictive value of tonic immobility for posttraumatic stress symptoms in a non-clinical sample. METHODS One hundred and...
