Types of Treatment in RCTs
Studies in the PTSD-Repository were categorized into the following 8 types of treatment: psychotherapy (trauma-focused versus non-trauma focused), pharmacotherapy, complementary and integrative health (CIH), nonpharmacologic biological, nonpharmacologic cognitive, collaborative care, control and "other treatments" that do not fit into the other categories.
Psychotherapy is talk therapy with a licensed provider and can be used with subclassifications of “trauma-focused” or “non-trauma-focused." Pharmacotherapy uses medications; it can be grouped into drug classes such as antidepressants and antiadrenergic medications. Both antidepressants and antianxiety medications are further classified into more specific subcategories. Complementary and integrative health (CIH) represents
a wide category of approaches that are considered to be outside the standard in the current practice of Western medicine or that are used in coordination with conventional approaches. Nonpharmacologic biological treatments use a medical device or medical procedure of some kind. Nonpharmacologic cognitive treatments teach cognitive skills to improve attention. Collaborative care treatments are those in which integrated medical and mental health treatment is delivered, often in primary care by nurse managers. Controls are comparison conditions such as placebo pill, waitlist and treatment as usual (when treatment as usual cannot be clearly defined as another specific treatment). The Other Treatments category includes studies that did not fit the main 6 classifications (e.g., animal-assisted, physical therapies, and internet-based facilitated self-help).
If a study compared more than 1 type of treatment, both treatment types were coded. For example, some studies are coded as psychotherapy and pharmacotherapy
, psychotherapy and CIH
or other mixed
. The table below shows the treatment categories along with some specific treatments that fall under those categories. The list of specific treatments is not exhaustive. To search for a specific treatment in the PTSD-Repository, go to the Study Interventions
dataset. From there you can search for a Treatment Name (assigned by the investigators) or a Standardized Treatment Name (a more general category assigned by the National Center for PTSD).
