Note on provider involvement: This provider has not agreed to EIF’s terms of reference, and the assessment has not been conducted and published with the full cooperation of the programme provider. Some or all information on this programme has been obtained from publicly available sources, and so assessments may not include all relevant evidence and published information may contain inaccuracies on programme details.

Prolonged Exposure Therapy-Adolescent (PE-A) is a targeted indicated programme for adolescents (between the ages of 13 to 18) who have experienced trauma. It is delivered in outpatient health settings and community centres and aims to support children to develop emotional processing skills to reduce the impact of their traumatic experiences, resulting in a decrease in symptoms associated with posttraumatic stress disorder (PTSD) and other trauma-related conditions.

  • PE-A is a form of cognitive behavioural therapy and was adapted from the widely studied and empirically supported adult treatment protocol. It provides psychoeducation about the effects of trauma and then focuses on helping adolescents to systematically and repeatedly confront trauma-related memories (imaginal exposure) and reminders (in vivo exposure). 
  • It is intended for adolescents who are exhibiting PTSD and related symptoms. 

EIF Programme Assessment

Evidence rating
3

Prolonged Exposure Therapy-Adolescent has evidence of a short-term positive impact on child outcomes from at least one rigorous evaluation.

What does the evidence rating mean?

Level 3 indicates evidence of efficacy. This means the programme can be described as evidence-based: it has evidence from at least one rigorously conducted RCT or QED demonstrating a statistically significant positive impact on at least one child outcome.

This programme does not receive a rating of 4 as it has not yet replicated its results in another rigorously conducted study, where at least one study indicates long-term impacts, and at least one uses measures independent of study participants. 

What does the plus mean?

The plus rating indicates that this programme has evidence from at least one level 3 study, along with evidence from other studies rated 2 or better.

About the programme

What happens during delivery?

How is it delivered?
  • Prolonged Exposure Therapy-Adolescent is delivered in once to twice weekly sessions of 60 to 90 minutes duration in eight to 15 sessions. It is delivered by mental health professionals individually to young people. 
What happens during the intervention?
  • PE-A aims to improve the participants’ ability to emotionally process their traumatic experiences and consequently diminish posttraumatic stress disorder and other trauma-related symptoms 
  • Participants are encouraged to repeatedly approach situations or activities they are avoiding because they remind them of their trauma (in vivo exposure) as well as to revisit the traumatic memory several times through retelling it (imaginal exposure) 
  • Psychoeducation about common reactions to trauma as well as breathing retraining exercises are also included in the treatment 

What are the implementation requirements?

Who can deliver it?
  • The practitioner who delivers this programme is a licensed mental health professional or those working under the supervision of a licensed mental health professional. Psychology, social work, and nursing staff can implement PE-A in their respective roles.  
What are the training requirements?
  • The practitioners have four full days of programme training.   
How are the practitioners supervised?

Not available

What are the systems for maintaining fidelity?
  • Training manual 
  • Video or DVD training 
  • Face-to-face training 
  • Fidelity monitoring 
Is there a licensing requirement?

How does it work? (Theory of Change)

How does it work?

PE-A is based on cognitive behavioural therapy and aims to promote the client's ability to emotionally process their traumatic experiences and consequently diminish posttraumatic stress disorder (PTSD) and other trauma-related symptoms

Prolonged Exposure Therapy-Adolescent

About the evidence

Prolonged Exposure Therapy for Adolescents most rigorous evidence comes from two RCTs which was conducted in the USA and South Africa.

 

The studies identified statistically significant positive impact on a number of child outcomes. 

  

This programme has evidence from at least one rigorously conducted RCT along with evidence from an additional comparison group study.  Consequently, the programme receives a 3+ rating overall.

Study design and sample

The first study is a rigorously conducted ​RCT​. This study involved random assignment of 61 adolescents to a PE-A treatment group and a ‘supportive counselling’ control group. This study was conducted in the US, with a sample of girls aged 13 to 18 (average age 15) who were exhibiting PTSD symptoms for longer than three months and were seeking treatment at a rape crisis centre. More than half (56%) were Black, 18% were White, 16% were Hispanic, 7% provided no response, and 3% were biracial. 

Measures 

  • The presence of PTSD diagnosis was measured using the Schedule of Affective Disorders and Schizophrenia for School-Age Children (diagnostic interview). 
  • PTSD symptoms severity were measured using the Child PTSD Symptom Scale–Interview (diagnostic interview) and the Child PTSD Symptom Scale–Self-Report (self-report). 
  • Depressive symptoms were measured using the Children’s Depression Inventory (self-report). 
  • Global functioning was measured using the Children’s Global Assessment Scale (direct assessment). 

Findings 

This study identified statistically significant positive impact on a number of ​child​ outcomes. These include: 

  • Decreased PTSD symptoms 
  • Decreased depressive symptoms 
  • Loss of PTSD diagnosis 
  • Increased global functioning 

Study 1b and 1c describes additional outcomes from study 1a described above.  In this case: 

  • At 3-,6-, and 12-month post-intervention, emotional and behavioural problems were measured using the Youth Self-report Scale (self-report) 
  • Suicidal ideations were measured using the Children’s Depression Inventory (self-report)
These studies identified statistically significant positive impact on a number of ​child​ outcomes. These include: 

  • Decreased externalising symptoms 
  • Decreased suicidal ideations 
  • Decreased rule breaking behaviour 
  • Decreased aggressive behaviour 
  • Decreased conduct problems
