We used the five GRADE considerations (study limitations, consistency of effect, imprecision, indirectness, and publication bias) to assess the certainty of the body of evidence for each outcome, and to draw conclusions about the certainty of evidence within the text of the review. One of the main considerations for downgrading GRADE judgements was risk of bias. Concerns over the certainty of the evidence also limit the extent to which conclusions can be generalised. For details of the risk of bias judgements for each study, see the Characteristics of included studies table and the graphical representation of risk of bias presented in Figure 2 and Figure 3. They can be distinguished based on the type and level of therapist assistance provided, which can vary widely between interventions. Typically the purpose of guidance is in providing support, including recognising and reinforcing an individual’s engagement with the self‐help materials, for example through weekly feedback (Berger 2017), in the form of email, text, telephone, video meetings, or in‐person face‐to‐face sessions.

Psychodynamic (PDT)‐based interventions are one example of such preferred approaches, this is despite comparatively limited available evidence supporting their effectiveness for treating PTSD. Mindfulness-based interventions function both as transdiagnostic adjunctive treatments to CBT for patients with anxiety and stress disorders as well as stand-alone treatments. Mindfulness is the practice of nonjudgmental awareness of the present moment experience. The aim of these interventions is to reduce emotional dysregulation and reactivity to stressors.
- There was insufficient data to perform subgroup analyses and determine the potential influence of, type of therapist assistance, participant subgroups, type of recruitment, type of CBT, baseline symptom severity, trauma type and context, or type of device.
- Medications are sometimes used as an adjunct to one of the therapies described above.
- CBT can also teach you how to communicate more effectively and manage your emotions to improve your relationships.
- In studies comparing PDT with CBT, only one study found PDT to be as effective as CBT (Levi et al., 2015), and only one study found PDT to be more effective than CBT (D’Andrea & Poole, 2012) in the treatment of PTSD.
Risk of bias in included studies
Common mindfulness-based interventions include manualized group skills training programs called mindfulness-based stress reduction (MBSR) and mindfulness-based cognitive therapy (11). MBSR involves eight, 2–2.5-hour sessions with an instructor, in conjunction with a daylong retreat, weekly homework assignments, and practice sessions. Modules are designed https://ecosoberhouse.com/ to train participants in mindful meditation, interpersonal communication, sustained attention, and recognition of automatic stress reactivity. Mindfulness-based cognitive therapy has a structure similar to MBSR but includes cognitive therapy techniques to train participants to recognize and disengage from negative automatic thought patterns (12).
Clinical diagnostic
A total of 26 studies were subject to full‐text screening, with 12 studies judged to have met the inclusion criteria and subsequently included for full review. Author(s), population, study design, intervention(s), dropout, outcomes measure(s), results, and follow‐up data for the 12 papers selected for review were extracted into data tables summarised in Table 3. Assessment of methodological quality was guided by CASP (Critical Appraisal Skills Programme) critical appraisal checklists and is presented in Table 3 with additional narrative synthesis across subsequent sections of the review.

Graded task assignments are manageable steps to decrease apathy and procrastination and overcome anxiety-provoking situations. If you’re depressed or anxious, for example, but want to plan an outing with a friend to go to a movie, the first step might be deciding which friend to go with. The next steps could involve calling your friend and choosing which movie to see.
What are the risk factors for PTSD?
Over-accommodation is changing ones beliefs to prevent trauma from occurring in the future, which may result in beliefs about the world being dangerous or people being untrustworthy (e.g., “because this happened, I cannot trust anyone”). CPT allows for cognitive activation of the memory, while identifying maladaptive cbt interventions for substance abuse cognitions (assimilated and over-accommodated beliefs) that have derived from the traumatic event. The main aim of CPT is to shift beliefs towards accommodation (Resick and Schnicke, 1992). Early trauma can lead to guilt, anger, feelings of powerlessness, self-harm, acting out, depression, and anxiety.
- However, we could not identify published protocols for the included studies, and, therefore, it was possible that other outcomes of interest were collected but not reported.
- There is no official accreditation for trauma-focused cognitive behavioral therapy, though supplemental trainings and courses exist.
- Some people may need to try different treatments to find what works best for their symptoms.
- Imel et al. (2013) did find evidence across three relatively large trials that dropout is lower in present centered therapy (PCT; 22%) compared to trauma specific treatments (36%).
- For instance, patients with this disorder may fear that they will make many verbal faux pas (e.g., saying “uh” more than 30 times) during a conversation.
Two review authors independently screened the abstracts identified by the literature search; read all potentially relevant studies; assessed each study against the inclusion criteria; extracted data from the written reports; and rated each study for risk of bias. We discussed any disagreements with a third review author and reached unanimous decisions for inclusion and classification. We carefully followed guidelines set out by Cochrane on statistical methods and used GRADE to assess the certainty of evidence (Andrews 2013). Following these procedures minimised the potential for bias, but some unavoidable issues remained. We did not exclude studies on the basis of duration of symptoms and because we did not stipulate that PTSD symptoms would need to be present for at least one month as an eligibility criterion, we cannot be certain of the number of participants fulfilling this diagnostic threshold.

Overall completeness and applicability of evidence
For crossover trials, we only used data from the first randomisation period to avoid a carry‐over effect. We did not use sample size or publication status to determine whether a study should be included. Two commonly cited epidemiological studies, conducted in Australia and the USA, demonstrated high levels of PTSD comorbidity, up to 88% in men and 80% in women, with around 50% experiencing three or more comorbidities. PTSD was often primary to substance use and affective disorders and in half of cases to be primary to anxiety disorders (Creamer 2001; Kessler 1995).
