Comparateur actif: 90 minute Prolonged Exposure Sessions
Prolonged Exposure Therapy for PTSD consists of 10 to 15 weekly or twice-weekly sessions, each lasting about 90 minutes, with 40 to 60 minutes imaginal exposure.
|
Prolonged exposure therapy (PE), a specific exposure therapy program for PTSD is a highly effective treatment for PTSD.
The key components of PE are imaginal exposure to the traumatic event and processing it (revisiting of the traumatic memory in imagination) followed by processing of the revisiting experience, and in vivo exposure to avoided trauma-related situations and objects.

Expérimental: 60 minute Prolonged Exposure Sessions
This treatment condition is a modified version of Prolonged Exposure therapy for PTSD.
It consists of 10 to 15 weekly or twice-weekly sessions, each lasting about 60 minutes, with 20 minutes imaginal exposure.

Change in PTSD Symptom Scale, Interview Version (PSS-I; Foa, Riggs, Dancu, & Rothbaum, 1993; Powers, Gillihan, Rosenfield, Jerud & Foa, 2012)
Délai: Pre-treatment through 6 month follow-up
|
The PSS-I will be administered on 4 separate occasions We will measure the change in PSS-I scores from pre-treatment to post-treatment, 3 month follow-up, and 6 month follow-up. The PSS-I is a 20-minute, 17-item clinical interview that evaluates DSM-IV PTSD symptoms on a frequency/severity scale. The interview yields a full-scale score and subscales for each of the three PTSD symptom clusters. Psychometric studies revealed internal reliability of .91 for the full scale, and .78, .80, and .82 for the reexperiencing, avoidance and arousal clusters (Foa & Tolin, 2000). |

Posttraumatic Diagnostic Scale (PDS; Foa et al., 1997)
Délai: Pre-treatment through 6 months post-treatment
|
The PDS will be administered at every other treatment session and at post-treatment, 3 month follow-up, and 6 month follow-up. The measure will be used to closely monitor treatment progress and help assess severity of symptoms. The PDS is a 17-item self-report measure that provides total and subscale severity scores and categorical classification of PTSD. The PDS demonstrated high internal consistency (.92 total, .78 re-experiencing, .84 avoidance, and .84 hyperarousal). Test-retest reliability is good, ranging from .74 to .85. High diagnostic agreement (82%) with the SCID-IV was noted: sensitivity was .89, and specificity, .75. The PDS is highly related to other measures of trauma related psychopathology. Participants will complete this measure at the beginning of every other treatment session. |

Beck Depression Inventory (BDI; Beck et al., 1961)
Délai: Pre-treatment through 6 month follow-up
|
The BDI will be administered at every other treatment session and at post-treatment, 3 month follow-up, and 6 month follow-up. The measure will be used to closely monitor treatment progress and help assess severity of symptoms. The BDI is a 21-item scale assessing depression. The inventory's internal consistency ranges from .58 to .93, test-retest reliability ranges from .69 to .90. Participants will complete this report measure at the beginning every other treatment session. |

Post-Traumatic Cognitions Inventory (PTCI; Foa et al., 1999)
Délai: Pre-treatment through 6 month follow-up
|
The PTCI will be administered at every other treatment session and at post-treatment, 3 month follow-up, and 6 month follow-up. The measure will be used to closely monitor treatment progress and help assess severity of symptoms. This 36-item instrument assesses post-trauma cognitions across self, world, and self-blame and yields a total score. The scale has high internal consistency (.97, .88, .86, 97, respectively) and correlates well with PTSD severity, anxiety, and depression (.44 to .79). This 36-item instrument assesses dysfunctional post trauma cognitions theoretically thought to underlie the development of PTSD. Participants will complete this measure at the beginning of every treatment session. |
