NCT03391297

Brief Summary

The present study aimed to investigate the efficacy of 60-minute sessions of prolonged exposure (PE) for patients with posttraumatic stress disorder (PTSD) in Taiwan. A systematic case study will be employed to compare the efficacy of 60-minute PE session versus standard 90-minute session with eight Taiwanese PTSD patients. Participants will include the individuals aged 18 or older who meet a diagnosis of DSM-5 PTSD and to experience moderate to severe symptoms for at least 3 months. Those who have current substance dependence, psychosis, and acute suicidality (i.e., recent suicidal ideation with intent and plan) will be excluded. Participants will receive 10-15 weekly session of PE treatment with 60- or 90-minute sessions. The investigators hypothesized that: (a) 60-minute PE is as effective as 90-minute PE in reducing PTSD and depressive symptoms as well as in promoting posttraumatic growth (PTG); and (b) the treatment gains will be maintained at 3-month follow-up.

Outcome Measures

Primary Outcomes (1)

  • Interviewer-assessed PTSD diagnosis and symptoms

    as measured by the Chinese version of the PTSD Symptoms Scale Interview for DSM-5 (PSSI-5) (Foa et al., 2016). The tota score ranged from 0 to 80, with higher scores indicating greater PTSD symptoms.

    Pre-treatment through three-month follow-up

Secondary Outcomes (4)

  • Self-reported PTSD symptoms

    Pre-treatment through three-month follow-up

  • Self-reported depressive symptoms

    Pre-treatment through three-month follow-up

  • Self-reported posttraumatic growth

    Pre-treatment through three-month follow-up

  • Self-reported posttraumtic negative cognitions

    Pre-treatment through three-month follow-up

Study Arms (2)

60-minute Prolonged Exposure Therapy

EXPERIMENTAL

This condition is a modified version of Prolonged Exposure Therapy for PTSD. It consists of weekly 60-minute sessions, with at least 20 minutes imaginal exposure.

Behavioral: Prolonged Exposure Therapy

90-minute Prolonged Exposure Therapy

ACTIVE COMPARATOR

This condition is standard Prolonged Exposure Therapy. It consists of 10 to 15 weekly sessions, each lasting about 90 minutes, with 40-60 minutes imaginal exposure.

Behavioral: Prolonged Exposure Therapy

Interventions

PE consists of 10-15 treatment sessions. Treatment includes psychoeducation, in vivo exposure (i.e., confronting trauma-related situations and objects that are being avoided), imaginal exposure (i.e., revisiting and recounting traumatic memory) followed by processing (discussing the experience of revisiting the trauma memory, with a focus on new learning and changed beliefs or perspectives).

Model Details: Prolonged exposure therapy (PE), a specific exposure therapy for PTSD, has been proved an effective treatment for PTSD. PE usually consists of 10-15 individual sessions. Treatment includes psychoeducation, in vivo exposure (i.e., confronting trauma-related situations and objects that are being avoided), imaginal exposure (i.e., revisiting and recounting traumatic memory) followed by processing (discussing the experience of revisiting the trauma memory, with a focus on new learning and changed beliefs or perspectives).
