The literature search yielded 517 citations. Upon screening titles and abstracts, 62 potentially relevant articles were retrieved for full-text review. One additional relevant written report was retrieved from database alerts and included in the assay. Of the 63 potentially relevant articles, 34 reports representing xvi studies were included in this review. Of those xvi studies, 10^{xiv – 23} were RCTs and 6^{24 – 29} were non-RCTs. One additional written report was identified from the final database alert.^xxx As this study was identified after all analyses were complete, its findings have been summarized without inclusion in the principal analyses and without inclusion in the GRADE procedure. The report selection process is outlined in a PRISMA flowchart (Appendix ii). The lists of included and excluded studies are shown in Appendix 3 and Appendix 4, respectively.

Study Characteristics

The characteristics of the included studies with brief definitions of the interventions are summarized in Appendix five.

Randomized Controlled Trials

All of the RCTs were conducted at outpatient clinics. The number of participants randomized in the trials ranged from 59¹⁶ to 405.¹⁴ The follow-up period ranged from one month¹⁹ to 12 months.^{xv , 21} The mean age of participants ranged from 32 years^{twenty , 21} to 54 years.¹⁹ The proportion of males ranged from 0%^{14 , 15 , 20} to 97%.¹⁶ The blazon of trauma was heterogeneous among study populations and could be divided into two categories: childhood and adult sexual trauma^{fourteen , 15 , 17 – 20 , 22} and combat-related trauma.^{sixteen , 21} V studies^{14 , xv , 17 , 20 , 23} had civilian populations and five^{sixteen , eighteen , 19 , 21 , 22} had military populations. The elapsing of trauma was reported in iv studies,^{15 , 17 , 20 , 22} and was non reported in six studies.^{14 , sixteen , 18 , 19 , 21 , 23} CPT was given in individual settings,^{16 – 20 , 22} in group settings,^{21 , 23} or as a combination of both group and private.^{14 , 15} The included trials compared CPT with WL/UC (a group of terminologies included wait-list, delayed treatment, treatment as usual [education and supportive counselling or not-trauma-focused symptom direction], and as-needed private back up),^{14 – 17 , 19 , 20} PE,²⁰ PCT,^{eighteen , 21 , 22} and with MeST.²³ The definitions of the interventions and comparators are briefly presented in Appendix five. The almost-reported outcomes were PTSD symptom severity and depression. PTSD symptom severity was assessed using either clinician-administered scales or self-reported scales. Low symptoms were assessed using cocky-reported scales. QoL was reported in ii studies.^{16 , 17}

Comparative Non-randomized Controlled Trials

Three studies were nautical chart reviews^{24 – 26} and 3 were cohort studies.^{27 – 29} Of the six studies, ane included noncombatant women who experienced sexual violence²⁷ and the remainder examined a veteran population who had combat-related trauma.^{24 – 26 , 28 , 29} The mean age of participants ranged from 30.6²⁷ to 61.9 years.²⁸ The proportion of males ranged from 0²⁷ to 100.^{24 , 28} The interventions of the studies included CPT provided in a grouping setting^{24 , 27 – 29} or in a combination of group and private settings.^{25 , 26} The comparators were wait-list or usual care (a group of terminologies that included await-list, trauma-focused therapy, trauma group exposure, and long-term process [psychotherapy]),^{24 , 25 , 27 , 28} PE,^{26 , 29} and a combination of EMDR and group CPT.²⁵ Trauma group exposure may exist different than other WL or UC controls, since it involves one of 2 master components of PE, trauma-focused in vivo exposure. The definitions of the interventions and comparators are briefly presented in Appendix 5. PTSD symptoms and depression severity were the almost mutual outcomes assessed using cocky-reported instruments. QoL was reported in one study.²⁴

Disquisitional Appraisal of Individual Studies

Randomized Controlled Trials

The method of randomization was reported in five trials,^{fourteen , 16 , 17 , 22 , 23} which were judged to be at low risk of bias, while five other trials^{xv , eighteen – 21} provided insufficient information most randomization. Viii^{14 – 21} out of 10 trials did not study details of allocation concealment, and were judged to be unclear in terms of the risk of bias. All trials were judged to be at unclear to high adventure of bias regarding the blinding of participants and personnel, which are hard to achieve in psychological therapy. All the same, blinding of outcome cess was reported in six trials.^{14 , sixteen , xviii , 19 , 21 , 22} Information technology was unclear whether or not the outcome assessors were blinded in four trials.^{15 , 17 , 20 , 23} All trials except one²⁰ were judged to be at high risk of attrition bias, since the dropout rates were moderate to high (approximately 15% to thirty%) and the method for handling of missing data was not reported. One trial¹⁸ had to exclude a large portion (73%) of the study population (data of two therapists) due to inconsistencies in ratings by therapists. Nine out of 10 trials had a small-scale sample size (ranging from xviii to 171 patients) that lacked ability and generalizability. The period of follow-up was brusk, because it was impractical and unethical to have a long follow-up, particularly for the look-list control group. Follow-up rates were low in virtually trials. It was difficult to judge differences in the level of competency of therapists between groups, and whether or non they were randomly assigned. Nonetheless, the majority of the trials had clear objectives and conspicuously described the methods, validated instruments were used to assess important outcomes, and dropout rates were reported, but the reasons for treatment discontinuation were not clearly described.

Non-randomized Controlled Trials

In non-RCTs, factors such as reporting, external validity, internal validity, and power were considered in the cess of the risk of bias (Appendix 6). 5^{25 – 29} out of 6 studies did non clearly written report the characteristics of participants at baseline to show whether there were differences between treatment groups. It was impossible to know how participants were selected in each handling grouping in those studies. It was also unclear if the outcome assessors were blinded in all studies. None of the studies included ability calculations to determine a sufficient sample size to detect a clinical of import effect. 2 studies^{25 , 28} had small sample sizes (N = 51 and 21, respectively), which was distributed among iii treatment groups. There was a high run a risk of bias due to the lack of treatment adherence and potential differences in therapist competency in the non-RCTs. In all studies, there was also take a chance of reporting bias, since only self-reported measures were used. Taken together, all studies were judged to exist at loftier take chances of bias.

Change in Severity of Mail-traumatic Stress Disorder Symptoms Rated by Clinician

Five RCTs^{xv – 17 , 19 , twenty} with a full of 357 participants used the CAPS to assess the severity of PTSD symptoms at baseline and at end of treatment. The CAPS ranges from 0 to 136, and participants who entered the studies had an average of 75 points at baseline, which is considered astringent. Improvement in PTSD symptoms is indicated by a decrease in CAPS scores. The Doctor in the changes from baseline between CPT and WL/UC was −31.35 (95% confidence interval [CI], −40.84 to −21.86) (Effigy 1, Appendix 7). For absolute effects, CAPS scores were lowered by six points for WL/UC and past 37.35 points for CPT at the cease of treatment (Table 2). The overall quality of evidence was moderate.

Compliance Assessed with Number of People Who Completed Treatment

Six RCTs^{xiv – 17 , 19 , xx} with a total population of 804 participants reported the number of patients who completed the study at stop of treatment. There was no deviation between the CPT and WL/UC groups (73% versus 71%; relative risk [RR] 0.96; 95% CI, 0.85 to i.x) (Figure 20). The quality of bear witness was moderate (Table 2).

Quality of Life

Ii RCTs^{16 , 17} and one observational study²⁴ reported QoL every bit an outcome. In the RCT by Galovski 2012,¹⁷ participants in the CPT group compared with WL control had a greater (six- to 79-fold) comeback in QoL as assessed using the Quality of Life Inventory (QOLI) and the Medical Effect Study 36-Item Short Form Wellness Survey (SF-36). In the RCT by Forbes 2012,¹⁶ using the Earth Health System Quality of Life (WHOQOL) scale to assess QoL, CPT was found to improve the psychological, social, and ecology subscales by iv-fold, v-fold, and three-fold, respectively, but there was no change on the physical subscale, compared with 'treatment as usual' which varied depending on the care provider. Treatment as usual included education and supportive counselling, non-trauma focused symptom management, or CBT with elements of exposure. All the same, the observational study by Alvarez 2011²⁴ did not discover any difference in any subscales of the WHOQOL betwixt CPT and psycho-education and patient autobiographical review, although QoL seemed to improve in both groups.

Remission

The BASS 2013 study^xiv did not measure remission, as not all patients had a confirmed PTSD diagnosis; rather, it reported the number of participants with probable PTSD before treatment, at the end of treatment, and after half dozen months of follow-up. At baseline, probable PTSD was sixty% (94/157) in the CPT group and 83% (205/248) in the individual support grouping. At the end of treatment, the number dropped to 8% (9/114) in the CPT grouping and 54% (85/156) in the private back up grouping. Afterwards six months of follow-upwards, it was 9% (12/138) and 42% (73/175), respectively.

Cerebral Processing Therapy Compared with Nowadays-Centred Therapy

Change in Severity of Post-traumatic Stress Disorder Symptoms Rated by Clinician

Two RCTs^{21 , 22} with a total population of 182 participants used ii different instruments to appraise the severity of PTSD symptoms. The SMD of the changes from baseline at the stop of treatment was −0.59 (95% CI, −1.52 to 0.33) (Figure xxx, Appendix 9). The SMD was back-translated using the SD of the Suris 2013 report,²² which assessed the severity of PTSD using the CAPS (calibration: 0 to 136), and participants had an average of 84 points at baseline. The calculated Medico was −2.88 (–7.42 to one.61), which was not statistically significant. For absolute effects, PCT lowered scores by xv points, while CPT lowered scores by 17.88 points on the CAPS at the end of handling (Table 4). The quality of evidence was very low.

Comparison 3 — Cognitive Processing Therapy Compared with Present-Centred Therapy.

The two RCTs^{21 , 22} had results of follow-upwardly for six and 12 months. The SMDs were −0.14 and −0.70; the overall SMD was −0.43 (95% CI, −0.97 to 0.11) (Figure 31). Based on CAPS, there was no statistically significant difference, with a calculated MD of −2.08 (95% CI, −4.69 to 0.53). For accented effects, Percent lowered scores by 22 points, while CPT lowered scores past 24.08 points on the CAPS at the end of follow-upwards (Tabular array 4). The quality of prove was very depression.

Modify in Severity of Mail-traumatic Stress Disorder Symptoms Rated Using Self-Reported Instruments

Three RCTs^{xviii , 21 , 22} with a total population of 227 participants used dissimilar instruments to assess the severity of PTSD symptoms. The SMD in the changes from baseline at the end of treatment was −1.03 (95% CI, −two.36 to 0.30) (Figure 32). The SMD was back-translated using the SD of the Suris 2013 study,²² which assessed the severity of PTSD using the PCL (scale: 17 to 85), and participants had an boilerplate of 65 points at baseline. The calculated MD was −3.05 (–six.96 to 0.89), which was non statistically meaning. For absolute effects, PCT lowered scores by 8 points, while CPT lowered scores past 11.05 points on PCL at the terminate of handling (Table 4). The quality of show was very low.

The three RCTs^{thirteen , 21 , 22} also had results of follow-up for half dozen months, vi months, and 12 months, respectively. The SMDs were −0.2, −0.six, and −2.1; the overall SMD was −0.97 (95% CI, −ii.13 to 0.18) (Figure 33). Based on the PCL, the calculated Md was −ii.86 (95% CI, −6.28 to 0.53), which was not statistically significant. For absolute effects, Pct lowered scores by 9 points, while CPT lowered scores by 11.86 points on the PCL at the end of treatment (Table 4). The quality of show was very low.

Modify in Severity of Depression Symptoms

Ii RCTs^{21 , 22} with a total population of 181 participants used different self-reported instruments to assess the severity of low symptoms. The SMD of the changes from baseline at the end of handling was −0.threescore (95% CI, −1.28 to 0.08) (Figure 34). The SMD was dorsum-translated using the SD of the Suris 2013 study,²² which assessed the severity of low using the Quick Inventory of Depressive Symptomatology (QIDS) (calibration: 0 to 27), and participants had an boilerplate of 16 points at baseline. The calculated MD was −0.68 (95% CI, −1.45 to 0.09), which was not statistically significant. For accented effects, Percentage lowered scores past 2 points, while CPT lowered scores by two.68 points on the QIDS scale at the cease of treatment (Table iv). The quality of evidence was very depression.

The two RCTs^{21 , 22} also had results of follow-upwardly for six and 12 months. The SMDs were −0.2 and −1.eight; the overall SMD was −1.01 (95% CI, −2.61 to 0.59) (Figure 35). Based on QIDS, there was no difference between CPT and Pct, with a calculated MD of −i.12 (95% CI, −two.9 to 0.65). Percent lowered scores by 2 points, while CPT lowered scores by 3.12 points on QIDS at the end of follow-upward (Table four). The quality of prove was very depression.

Compliance Assessed With Number of People Who Completed Handling

Two RCTs^{21 , 22} with a total population of 237 participants reported the number of patients who completed the study at end of handling. The proportion of patients completing treatment was lower in the CPT group compared with those in the Percent grouping (66% versus 82%; RR 0.82; 95% CI, 0.71 to 0.95) (Effigy 36). The quality of evidence was very low (Table 3).

Cerebral Processing Therapy Compared with Retentivity Specificity Grooming

I RCT²³ with 16 participants (eight civilians per group) compared CPT (group) with MeST, which taught individuals how to retrieve specific memories. MeST was first designed to treat depression.³¹ The severity of PTSD and depression were assessed using the self-reported instruments, i.eastward., the Modified PTSD Symptom Calibration (MPSS) and BDI-Two. In that location were no differences between groups for the improvement in PTSD and low symptoms at terminate of treatment and at three-month follow-upwardly (Figures 37 to 40 of Appendix ten, Table five). The study also showed no difference in the improvement in global performance and ability to call back specific memories between CPT and MeST. The quality of evidence was very low.

Cognitive Processing Therapy Compared with Eye Movement Desensitization and Reprocessing

No study was found that compared CPT with EMDR.

One observational written report²⁵ with 34 participants (17 military veterans in each group) compared CPT (individual and group) with EMDR plus CPT individual therapy. The outcomes considered in this written report were severity of PTSD, depression, and feet, which were assessed using self-reported instruments (i.e., the PCL, BDI, and Beck Anxiety Inventory [BAI], respectively). Based on very low-quality evidence, there were no differences between the CPT and the EMDR plus CPT groups for change in severity of PTSD (62.53 ± 9.72 versus 65.82 ± 13.52), alter in low symptoms (25.24 ± 12.81 versus 26.00 ± 13.11), and change in anxiety symptoms (25.88 ± 13.fourteen versus 23.47 ± 13.42) at end of treatment.

Cognitive Processing Therapy Compared with Dialogue Exposure Therapy

One RCT³⁰ was identified from the final alert (February eleven, 2016) comparison DET with CPT for adult outpatients suffering from PTSD later on a diversity of traumas. As it was identified after data analyses were consummate, its findings are summarized here without inclusion in the main or Class analysis. Both treatments achieved similar reductions in PTSD symptoms assessed using a self-reported instrument, the Touch of Outcome Calibration – Revised (IES-R). At pre-treatment versus mail-handling, the effect sizes (Hedges' g) for DET and CPT were 1.xiv and 1.57, respectively. The effects were stable afterwards vi-month follow-upward (1.33 versus 1.50). For overall psychological functioning and trauma-related knowledge measured by the Brief Symptom Inventory (BSI) and the Posttraumatic Cognitions Inventory (PTCI), respectively, CPT performed better than DET at the post-treatment assessment (BSI: 0.88 versus 0.64; PTCI: 1.03 versus 0.65). Dropout rates were similar for both treatments (post-treatment: 12.two% for DET and 14.9% for CPT).
