RESUMEN
The heterogeneity of the core symptoms of posttraumatic stress disorder (PTSD), high rates of comorbid mental and physical health conditions, and substantial impact of the disorder on functioning and well-being contribute to complex clinical presentations that can be challenging to treat. Despite these challenges, there are excellent manualized treatments for PTSD with significant empirical support. Although the success of frontline treatments for PTSD is evident, there remains room for improvement as indicated by suboptimal response and attrition rates. To address challenges to optimal therapy outcomes (COTOs), researchers have conducted numerous clinical trials designed to (a) enhance the core structure of treatment protocols to increase flexibility or (b) expand the protocols to address comorbid conditions that inhibit recovery. However, it is implausible to ever conduct the number of enhancement and expansion clinical trials necessary to test manual modifications for the universe of possible COTOs. This conceptual review describes the concept of a personalized model of therapy that leverages a case formulation approach to implementing an evidence-based treatment for PTSD. This personalized approach provides guidance for the clinician in assessing the patient's COTOs, monitoring them throughout treatment, and relying on the patient's idiosyncratic data to inform treatment decisions, including how and when to diverge from treatment when clinically indicated and ensuring a clear path to return to trauma-focused work when the COTO is stabilized. This personalized, case formulation approach to treating PTSD provides guidance for adopting a more flexible approach to treating clinically complex patients while ensuring fidelity to the protocol.
RESUMEN
PURPOSE: There is limited research exploring the usefulness of generic preference-based quality of life (GPQoL) measures used to facilitate economic evaluation in the context of posttraumatic stress disorder (PTSD). The aim of the current study was to explore the validity and responsiveness of a common GPQoL measure (Assessment of Quality of Life 8 Dimension [AQoL-8D]) in relation to a PTSD condition-specific outcome measure (Posttraumatic Stress Disorder Checklist for the DSM-5 [PCL-5]). METHOD: This aim was investigated in a sample of individuals (N = 147) who received trauma-focused cognitive-behavioural therapies for posttraumatic stress disorder. Convergent validity was investigated using spearman's correlations, and the level of agreement was investigated using Bland-Altman plots. Responsiveness was investigated by exploring the standardised response means (SRM) from pre-post-treatment across the two measures, which allow the comparison of the magnitude of change between the measures over time. RESULTS: Correlations between the AQoL-8D (dimensions, utility and summary total scores) and the PCL-5 total score ranged from small to large and agreement between the measures was considered moderate to good. While SRMs were large for the AQoL-8D and PCL-5 total scores, the SRM for the PCL-5 was nearly double that of the AQoL-8D. CONCLUSION: Our findings demonstrate that the AQoL-8D has good construct validity but present preliminary evidence that economic evaluations using only GPQoL measures may not fully capture the effectiveness of PTSD treatments.

Thompson-Hollands et al.'s (2020) commentary on our systematic review of exposure-based writing therapies for subthreshold and clinical posttraumatic stress symptoms (Dawson et al., 2020) emphasizes important questions about the impact of heterogeneity in drawing inferences from evidence reviews. In this reply, we discuss (a) our rationale for undertaking a systematic review that was broad rather than narrow in scope and (b) provide clarifications on how heterogeneity was considered in the meta-analyses that were conducted. We also strongly agree with Thompson-Hollands et al.'s recommendation that future research should focus on better understanding the mechanisms by which exposure-based writing therapies help reduce posttraumatic stress symptoms.

We undertook a systematic review to assess the efficacy of exposure-based writing therapies (WTs) for trauma-exposed adults with subthreshold or clinical levels of posttraumatic stress disorder. Four databases (PsycINFO, Medline, Wiley Online, PILOTS) were searched for randomized controlled trials (RCTs) of exposure-based WTs. A total of 13 RCTs that reported on results from 17 WT versus control comparisons were included. The primary outcomes were posttraumatic stress symptom severity at posttreatment and/or clinical response. An overall unclear or high risk of bias was identified in 84.6% of studies. In comparison to both waitlist k = 3, Hedges' g = -0.97, 95% CI [-1.20, -0.73], and placebo writing conditions, k = 9, Hedges' g = -0.48, 95% CI [-0.87, -0.08], WTs were more beneficial to participants. There was no evidence of a difference between WTs that were longer in duration compared to other psychotherapy, k = 2; pooled OR = 1.42; 95% CI [0.83, 2.43]. These findings indicate that exposure-based WTs are effective when compared to waitlist and placebo writing control conditions. The evidence needs to be considered in the context of the modest number of studies conducted to date, the high methodological heterogeneity between the studies, and the high or unclear risk of bias across many studies. Further research is needed to increase the evidence base regarding the efficacy of WTs for posttraumatic stress. Future research should also measure the mediators and predictors of outcomes to further develop protocols and understand which variants of WTs work for different populations or individuals.

BACKGROUND: The latest version of the International Classification of Diseases (ICD-11) proposes a posttraumatic stress disorder (PTSD) diagnosis reduced to its core symptoms within the symptom clusters re-experiencing, avoidance and hyperarousal. Since children and adolescents often show a variety of internalizing and externalizing symptoms in the aftermath of traumatic events, the question arises whether such a conceptualization of the PTSD diagnosis is supported in children and adolescents. Furthermore, although dysfunctional posttraumatic cognitions (PTCs) appear to play an important role in the development and persistence of PTSD in children and adolescents, their function within diagnostic frameworks requires clarification. METHODS: We compiled a large international data set of 2,313 children and adolescents aged 6 to 18 years exposed to trauma and calculated a network model including dysfunctional PTCs, PTSD core symptoms and depression symptoms. Central items and relations between constructs were investigated. RESULTS: The PTSD re-experiencing symptoms strong or overwhelming emotions and strong physical sensations and the depression symptom difficulty concentrating emerged as most central. Items from the same construct were more strongly connected with each other than with items from the other constructs. Dysfunctional PTCs were not more strongly connected to core PTSD symptoms than to depression symptoms. CONCLUSIONS: Our findings provide support that a PTSD diagnosis reduced to its core symptoms could help to disentangle PTSD, depression and dysfunctional PTCs. Using longitudinal data and complementing between-subject with within-subject analyses might provide further insight into the relationship between dysfunctional PTCs, PTSD and depression.

The Children's Post-Traumatic Cognitions Inventory (CPTCI) is a self-report questionnaire that measures maladaptive cognitions in children and young people following exposure to trauma. In this study, the psychometric properties of the CPTCI were examined in further detail with the objective of furthering its utility as a clinical tool. Specifically, we investigated the CPTCI's discriminant validity, test-retest reliability, and the potential for the development of a short form of the measure. Three samples (London, East Anglia, Australia) of children and young people exposed to trauma (N = 535; 7-17 years old) completed the CPTCI and a structured clinical interview to measure posttraumatic stress disorder (PTSD) symptoms between 1 and 6 months following trauma. Test-retest reliability was investigated in a subsample of 203 cases. The results showed that a score in the range of 46 to 48 on the CPTCI was indicative of clinically significant appraisals as determined by the presence of PTSD. The measure also had moderate-to-high test-retest reliability (r = .78) over a 2-month period. The Children's Post-Traumatic Cognitions Inventory-Short Form (CPTCI-S) had excellent internal consistency (α = .92), and moderate-to-high test-retest reliability (r = .78). The examination of construct validity showed the model had an excellent fitting factor structure (Comparative Fit index = 0.95, Tucker-Lewis index = 0.91, Root Mean Square Error of Approximation = .07). A score ranging from 16 to 18 was the best cutoff point on the CPTCI-S, in that it was indicative of clinically significant appraisals as determined by the presence of PTSD. Based on these results, we concluded that the CPTCI is a useful tool to support the practice of clinicians and that the CPTCI-S has excellent psychometric properties.

Screening is recommended as a simple method for identifying those who should be monitored for risk following trauma. Effective methods for implementing large-scale screening programs are yet to be established. This study tested the feasibility and utility of a screening program with hospitalized youth exposed to injury in 3 Australian hospitals. Eligible families (N = 1,134) were contacted and 546 children (48.0%) screened for risk of posttraumatic stress disorder (PTSD) at 1-2 weeks postinjury. There were 95 (17.4%) children whose screen result was at risk. A rescreening phase was introduced during the study, with 68 children completing the rescreen at 4-6 weeks postinjury, and 26 (38.2% of those rescreened) still at risk. Of those initially screened, 29 (5.3%) completed diagnostic assessments, 21 (3.8%) were diagnosed with partial or full PTSD, and 17 (3.1%) commenced treatment. Screening was successful at identifying and reaching children with PTSD, but the response rate was lower than expected, which limited the utility of the program. The addition of a rescreening phase demonstrated that not all at-risk children required intervention. These findings replicate previous studies that have shown natural remission in PTSD symptoms and highlight the potential for rescreening as part of a watchful waiting approach.

OBJECTIVES: Overgeneral autobiographical memory (OGM) refers to the impaired retrieval of specific events from autobiographical memory. This review examined OGM in children and adolescents to answer three main questions. First, do children demonstrate OGM? Second, how does the experience of OGM relate to childhood trauma and associated psychopathology? Third, is the CaR-FA-X model (Williams et al., 2007) able to explain OGM in child psychopathology once developmental issues have been considered? METHOD: Articles were identified in PsycINFO and PubMed searches using the terms overgeneral memory AND children, autobiographical memory specificity AND children, and autobiographical memory AND children. The authors reviewed 21 articles that examined OGM in young people aged 718 years. Effect sizes were calculated for each study. RESULTS: The review demonstrated consistent support for a relationship with trauma exposure and depression symptoms in childhood. Furthermore, OGM was found to predict depression symptoms. Limited support was provided for the efficacy of the CaR-FA-X model in young people. CONCLUSIONS: Future research will need to examine the influence of trauma characteristics on OGM development, along with the relationship of OGM to depression prognosis. Further investigation of the CaR-FA-X model is required and developmental aspects will need to be taken into account.

BACKGROUND AND OBJECTIVES: Cognitive models of posttraumatic stress disorder (PTSD) suggest that appraisals of traumatic sequelae and subsequent distress drive the development and maintenance of PTSD. Posttraumatic research has relied heavily on macro-longitudinal designs, with weeks or months between assessments of trauma-related cognitions and symptoms. The present study uses experience sampling methodology (ESM) better understand the day-to-day experiences of trauma exposed individuals. METHODS: One-hundred trauma exposed adults reported their posttraumatic symptoms, interpretations, and behaviours four times a day over a 10-day ESM period. RESULTS: As anticipated, within-person fluctuations in negative appraisals of intrusions and maladaptive coping strategies (e.g., thought suppression) were significantly positively associated with intrusion frequency and related distress. In all cases, the associations for negative appraisals and maladaptive coping were stronger with intrusion related distress than intrusion frequency. LIMITATIONS: The observed contemporaneous associations only demonstrate that variables reliably fluctuated together and cannot indicate causality. CONCLUSIONS: The findings demonstrate that day-to-day fluctuations in trauma related perceptions and sequelae are significant and should be explored alongside broader individual differences to advance our understanding of the development, maintenance, and treatment of PTSD.

Stepped care approaches have been developed to increase treatment accessibility for individuals with posttraumatic stress disorder (PTSD). However, despite guidelines recommending stepped care, it is currently unclear how the approach compares to other treatments for PTSD in terms of symptom reduction, cost, and client-rated acceptability. We conducted a systematic review and meta-analysis of randomized controlled and open trials evaluating stepped care prevention (i.e., targeting those with recent trauma exposure at risk of developing PTSD) and treatment approaches for adults and adolescents/children with PTSD. Eight prevention and four treatment studies were included. There was considerable variation in the sample types, stepped approaches, and control conditions. Most studies found no significant differences between stepped care (both prevention and treatment) and control (active and usual care) in terms of PTSD severity, loss of PTSD diagnosis, depression severity, and quality of life at the final follow-up. There was some evidence to suggest that stepped care was more cost-effective, and as acceptable or more acceptable compared to controls. Interpretations were tempered by high statistical heterogeneity, risk of bias, and lack of recommended evidence-based treatments. Stepped care can make PTSD treatment more accessible; however, more high-quality research is needed comparing stepped care to active controls.

OBJECTIVE: The Psychosocial Assessment Tool 2.0 (PAT-B) is an adaptation of an existing screening tool with the aim of the present study to examine its effectiveness and suitability to identify children and families at risk of emotional, behavioral, and social maladjustment following paediatric burns. METHODS: Sixty-eight children aged between 6 months - 16 years (M = 4.40) admitted into hospital following paediatric burns, and their primary caregivers, were recruited. The PAT-B comprises several dimensions including family structure and resources, social support, as well as caregiver and child psychological difficulties. Caregivers completed the PAT-B and several standardized measures for validation purposes (e.g., caregiver reports of family functioning, child emotional and behavioural problems, caregiver distress). Children old enough to complete measures reported on their psychological functioning (e.g., posttraumatic stress and depression). Measures were completed within 3 weeks of child admission and then again at 3 months after burn. RESULTS: The PAT-B demonstrated good construct validity, evidenced by moderate to strong correlations between the PAT-B Total and subscale scores and several criteria measures (family functioning, child behaviour and caregiver distress, child depressive symptoms, rs ranging from 0.33 -0.74). Preliminary support for criterion validity of the measure was observed when examined against the three tiers of the Paediatric Psychosocial Preventative Health Model. The proportion of families falling within these tiers of risk (Universal [low risk], 58.2%; Targeted, 31.3%; or Clinical range, 10.4%) was consistent with prior research. Sensitivity of the PAT-B to identify children and caregivers at high risk of psychological distress was 71% and 83%, respectively. CONCLUSION: The PAT-B appears to be a reliable and valid instrument for indexing psychosocial risk across families who have sustained a paediatric burn. However, further testing and replication using a larger sample size is recommended before the tool is integrated into routine clinical care.

BACKGROUND AND OBJECTIVES: Research shows that people can lack meta-awareness (i.e., being explicitly aware) of their trauma-related thoughts, which impacts our understanding of re-experiencing symptoms, a key symptom type in posttraumatic stress disorder (PTSD), assessed through self-report. This preliminarily study explored differences between (meta-)aware and unaware intrusion characteristics to understand why some intrusions are not immediately apparent to individuals. METHODS: Trauma-exposed participants (N = 78) were recruited from online crowd-sourcing platforms to complete an online meta-awareness task. During a reading task, participants were intermittently probed to index the occurrence of unreported (i.e., unaware) trauma-related intrusions. Once participants indicated trauma-related intrusions were present, they then completed a questionnaire that indexed intrusion characteristics. RESULTS: Although unaware intrusions did occur in a subset of the sample, there were no fundamental differences between aware and unaware intrusions in terms of modality of experience (imagery vs. non-imagery), meaningfulness, accessibility, or other characteristics (e.g., vividness). LIMITATIONS: There was potential for lower participant engagement and attention due to the online delivery of the meta-awareness task, which may have minimized meta-awareness failure. Future research could consider using a continuous measure to index levels of meta-awareness. In addition, recruiting clinical samples (e.g., individuals with PTSD) who typically experience multiple daily intrusions would allow generalizability of the current findings to be tested. CONCLUSIONS: Our findings from this preliminary study suggest that unaware and aware intrusions show more commonality than not in their characteristics, with further research required to improve our understanding of the mechanisms leading to meta-awareness or lack of in PTSD.

There is limited research on the concordance between client perceptions and clinician standards of the degree of symptom change required to achieve meaningful therapeutic improvement. This was investigated in an adult sample (Nâ¯=â¯147) who received trauma-focused cognitive-behavioral therapies for posttraumatic stress disorder (PTSD). We examined whether clients' benchmarks of change were related to actual outcomes and the relationship between client expectations and their treatment outcomes. Clients completed measures indexing the level of symptom reduction required (in their view) to reflect a benefit or recovery from treatment and treatment expectations. Actual PTSD severity was indexed pre- and posttreatment via self-report and clinician-administered interview. Results demonstrated that the amount of change clients said they required to experience a benefit or recovery was significantly larger than typical clinical research standards. Nonetheless, the majority of client benchmarks of change (79.7-81.8%) were consistent with clinical research standards of what constitutes benefit or recovery. Client benchmarks were generally positively correlated with their actual outcomes. Clients' belief that treatment would be successful was associated with greater reductions in PTSD symptoms. These findings provide preliminary evidence that the standards used to determine clinically significant change are somewhat consistent with clients' own perceptions of required symptom change.

The efficacy of a cognitive-behavioral treatment program for individuals with comorbid posttraumatic stress disorder (PTSD) and major depression (MDD) was examined. In an uncontrolled pre- and posttreatment study, participants attended 12-16 weeks of manualized therapy incorporating behavioral activation for depression in early sessions and exposure therapy and cognitive restructuring for PTSD in later sessions. Fourteen participants (of 20) completed treatment. Results indicated a significant decrease in PTSD and depression severity between pre- and midtreatment assessments; PTSD decreased further from mid- to posttreatment. Treatment gains were maintained at 3-month follow-up; 60% of participants no longer met PTSD criteria at 3-month follow-up, and 70% no longer met MDD criteria. The clinical implications of this phased approach to treat PTSD and depression comorbidity are discussed.

BACKGROUND AND OBJECTIVES: Trauma survivors often report trauma events inconsistently over time. Many studies, for example, have found that people report having experienced trauma events that they initially failed to report or remember, a phenomenon called "memory amplification." Other studies have found the opposite: people report experiencing fewer events over time. Nahleen, Nixon, and Takarangi (2019) asked participants at two time-points, with a six-month delay, whether they had experienced 19 sexual assault events on a yes/no scale. Participants reported fewer events over time, that is, memory for sexual assault did not amplify overall. In the current study, we assessed whether inconsistency in reports of trauma exposure over time may be attributed to changes in participants' belief that certain events were experienced. METHODS: We replicated Nahleen et al. (2019), but rather than respond to a yes/no trauma exposure scale, participants were required to rate the likelihood that each trauma event occurred on an 8-point scale (1 = definitely did not happen; 8 = definitely did happen). RESULTS: We found that participants believed that they were less likely to have experienced the sexual assault events at follow-up compared to initial assessment. LIMITATIONS: We could not corroborate trauma experiences or determine causality with our design. Further, not all of our findings were consistent with Nahleen et al. (2019). CONCLUSIONS: Sexual assault memories did not amplify over time, perhaps because, compared to other types of trauma, the idea of experiencing additional sexual assault events that were not actually experienced is less believable.

Individuals are not always aware of their mental content. We tested whether lack of awareness occurs in those who have experienced trauma, with and without posttraumatic stress disorder (PTSD). We also examined the role of proposed cognitive mechanisms (working memory and inhibition) in explaining unnoticed intrusions. Individuals with PTSD (nâ¯=â¯44), and varying levels of symptoms (high posttraumatic stress [PTS]: nâ¯=â¯24; low PTS: nâ¯=â¯37) reported on intrusive thoughts throughout a reading task. Intermittently, participants responded to probes about whether their thoughts were trauma related. Participants were "caught" engaging in unreported trauma-related thoughts (unnoticed intrusions) for between 24 and 27% of the probes in the PTSD and high PTS groups, compared with 15% of occasions in the low PTS group. For trauma-related intrusions only, participants lacked meta-awareness for almost 40% of probes in the PTSD group, which was significantly less than that observed in the other groups (â¼60%). Contrary to predictions, working memory and response inhibition did not predict unnoticed intrusions. The results suggest that individuals who have experienced significant trauma can lack awareness about the frequency of their trauma-related thoughts. Further research is warranted to identify the mechanisms underpinning the occurrence of unnoticed intrusions.

Cognitive Processing Therapy (CPT) is an effective treatment for posttraumatic stress disorder (PTSD); however, not every client achieves optimal outcomes. Data were pooled from four randomized trials in which female interpersonal trauma survivors completed CPT (N = 179). Random forests of classification trees were used to investigate the role of both baseline (e.g., demographics, trauma history, comorbid disorders) and session PTSD and depressive symptom scores on predicting trajectory and outcome. Of particular focus was whether those on track for poor outcome (e.g., non-response, partial treatment response) could be identified early in therapy. Results demonstrated inconsistent findings for discrimination between delayed responders (no early change but full response after 12 weeks of therapy) and those who either showed a partial response to treatment or did not respond at all; level of discrimination depended on the assessment point under study and the chosen comparison group. Those defined as clear and early responders, however, could be reliably differentiated from the other groups by session 4. Although it is possible to identify clients who will recover from PTSD by the middle of the CPT protocol, further work is needed to accurately identify those who will ultimately not recover from PTSD during a course of CPT.

BACKGROUND: Accidental injury represents the most common type of traumatic event to which a child or adolescent may be exposed, with a significant number of these children going on to experience posttraumatic stress disorder (PTSD). However, very little research has examined potential interventions for the treatment of PTSD in these children. The present trial aims to evaluate and compare child- and family-focused versions of a cognitive-behavioural early intervention for PTSD following accidental injury. METHODS/DESIGN: The principal clinical question under investigation is the efficacy of an early, trauma-focused cognitive-behavioural intervention for the treatment of PTSD in children following accidental injury. Specifically, we compare the efficacy of two active treatments (child-focused and family-focused CBT) and a waitlist control (no therapy) to determine which is associated with greater reductions in psychological and health-related outcome measures over time. The primary outcome will be a reduction in trauma symptoms on a diagnostic interview in the active treatments compared to the waitlist control and greater reductions in the family-compared to the child-focused condition. In doing so, this project will also trial a method of stepped screening and assessment to determine those children requiring early intervention for PTSD following accidental injury. DISCUSSION: The present trial will be one of the first controlled trials to examine a trauma-focused CBT, early intervention for children experiencing PTSD following accidental injury (as opposed to other types of traumatic events) and the first within a stepped care approach. In addition, it will provide the first evidence comparing the efficacy of child and family-focused interventions for this target group. Given the significant number of children and adolescents exposed to accidental injury, the successful implementation of this protocol has considerable implications. If efficacious, this early intervention will assist in reducing symptoms of traumatic stress as well as preventing chronic disorder and disability in children experiencing acute PTSD following accidental injury.

Three screening methods to predict posttraumatic stress disorder (PTSD) and depression symptoms in children following single-incident trauma were tested. Children and adolescents (N = 90; aged 7-17 years) were assessed within 4 weeks of an injury that led to hospital treatment and followed up 3 and 6 months later. Screening methods were adapted from existing instruments and examined (a) an Australian version of the Screening Tool for Predictors of PTSD (STEPP-AUS), (b) an abbreviated measure of initial PTSD severity, and (c) an abbreviated measure of initial maladaptive trauma-specific beliefs. The STEPP-AUS correctly identified 89% of the children who developed PTSD at 6-month follow-up and the 69% of children who were non-PTSD. Predictive performance of the others instruments was generally poor, and no instrument consistently predicted subclinical levels of depression.

Cognitive Processing Therapy (CPT) and Behavioural Activation Therapy (BA) were used to treat individuals with comorbid posttraumatic stress disorder (PTSD) and major depressive disorder (MDD). Fifty-two individuals (48 women, 4 men) were randomized to CPT alone (n = 18), CPT then BA for MDD (n = 17), or BA then CPT (n = 17). Presenting trauma was primarily interpersonal (87 %). Participants were assessed at pre-, posttreatment, and 6-month follow-up. PTSD and MDD symptoms were the main outcome of interest; trauma cognitions, rumination, and emotional numbing were secondary outcomes. All groups showed sizeable reductions in PTSD and depression (effect sizes at follow-up ranging between 1.02-2.54). A pattern of findings indicated CPT/BA showed better outcomes in terms of larger effect sizes and loss of diagnoses relative to CPT alone and BA/CPT. At follow-up greater numbers of the CPT/BA group were estimated to have achieved good end-state for remission of both PTSD and depression (49 %, CI95 [.26, .73]) relative to CPT alone (18 %, CI95 [.03, .38]) and BA/CPT (11 %, CI95 [.01, .29]). Although tempered by the modest sample size, the findings suggest that individuals with comorbid PTSD and MDD may benefit from having PTSD targeted first before remaining MDD symptoms are addressed.
