Brief early psychological interventions following trauma: a systematic review of the literature

Impact of healthcare interventions on distress following acute musculoskeletal/orthopaedic injury: a scoping review of systematic reviews

BACKGROUND

Musculoskeletal injuries can cause distress, and distress is associated with delayed recovery. Numerous interventions have been developed to facilitate recovery from injury, and several systematic reviews evaluate the efficacy of these interventions for reducing psychological distress.

OBJECTIVES

This scoping review aims to map the synthesised evidence for the relationship between treatment interventions and distress-related outcomes following acute injury. The objectives were (1) to describe the types of interventions that have been evaluated in relation to distress-related outcomes following accidental injury, (2) to examine the scope of distress-related outcomes that have been measured in relation to these interventions and (3) to explore the range of clinical professions that deliver these interventions.

DESIGN

We searched nine electronic databases and grey literature (to 21 April 2022). We included any systematic review reporting on the relationship between interventions delivered in the time following injury and distress-related outcomes. Data relevant to the specific objectives of this scoping review were extracted and described using narrative synthesis.

RESULTS

From 8412 systematic reviews imported for screening, 8266 unique records were screened. 179 were selected for full-text review. 84 systematic reviews were included in the study. Interventional types were pharmacological, psychological, exercise based, physical/manual therapies, virtual reality based, multimodal and workplace based. Interventions were delivered digitally, face to face and using virtual reality by a variety of healthcare professionals, including doctors, nurses, psychologists and physiotherapists. The most frequently reported distress-related variables included anxiety, depression, post-traumatic stress disorder diagnosis.

CONCLUSION

A wide range of interventions may help to mitigate distress following acute accidental musculoskeletal or orthopaedic injury. Even interventions that were not designed to reduce distress were found to improve distress-related outcomes. In view of the important role of distress in recovery from injury, it is recommended that distress-related variables are measured as core outcomes in the evaluation of treatments for acute injuries.

A pilot clinical trial of the Screening and Tool for Awareness and Relief of Trauma for survivors of gun violence

BACKGROUND

Survivors of gun violence have significant sequelae including reinjury with a firearm and mental health disorders that often go undiagnosed and untreated. The Screening and Tool for Awareness and Relief of Trauma (START) is a targeted behavioral mental health intervention developed for patients who come from communities of color with sustained and persistent trauma.

METHODS

In this pilot study, we evaluate the feasibility of completing a randomized controlled trial to test the START intervention. Using a mixed methods study design, we used both quantitative and qualitative data collection to assess the START intervention and the feasibility of completing a randomized controlled trial. The purpose of this study was to estimate important study parameters that would enable a future randomized controlled trial.

RESULTS

We were able to make conclusions about several crucial domains of a behavioral intervention trial: (1) recruitment and retention-we had a high follow-up rate, but our recruitment was low (34% of eligible participants); (2) acceptability of the intervention-the addition of audiovisual resources would make the tools more accessible; (3) feasibility of the control-more appropriate for a stepped wedge cluster randomized controlled trial design; (4) intervention fidelity-there was an 81% concordance rate between the fidelity survey results and the audio recordings; (5) approximate effect size-there was a 0.4-point decrease in the PTSD Checklist-Civilian Version in the control compared with a 10.7-point decrease in the treatment group for the first month.

CONCLUSION

While it was feasible to conduct a randomized controlled trial, our findings suggest that a stepped wedge cluster randomized controlled trial design may be the most successful trial design for the START intervention. In addition, the inclusion of a "credible messenger" to recruit participants into the study and the development of audiovisual resources for START would improve recruitment and effectiveness.

Pharmacotherapy for post traumatic stress disorder (PTSD)

BACKGROUND

Posttraumatic stress disorder (PTSD) is a prevalent and disabling disorder. Evidence that PTSD is characterised by specific psychobiological dysfunctions has contributed to a growing interest in the use of medication in its treatment.

OBJECTIVES

To assess the effects of medication for reducing PTSD symptoms in adults with PTSD.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL; Issue 11, November 2020); MEDLINE (1946-), Embase (1974-), PsycINFO (1967-) and PTSDPubs (all available years) either directly or via the Cochrane Common Mental Disorders Controlled Trials Register (CCMDCTR). We also searched international trial registers. The date of the latest search was 13 November 2020.

SELECTION CRITERIA

All randomised controlled trials (RCTs) of pharmacotherapy for adults with PTSD.

DATA COLLECTION AND ANALYSIS

Three review authors (TW, JI, and NP) independently assessed RCTs for inclusion in the review, collated trial data, and assessed trial quality. We contacted investigators to obtain missing data. We stratified summary statistics by medication class, and by medication agent for all medications. We calculated dichotomous and continuous measures using a random-effects model, and assessed heterogeneity.

MAIN RESULTS

We include 66 RCTs in the review (range: 13 days to 28 weeks; 7442 participants; age range 18 to 85 years) and 54 in the meta-analysis.  For the primary outcome of treatment response, we found evidence of beneficial effect for selective serotonin reuptake inhibitors (SSRIs) compared with placebo (risk ratio (RR) 0.66, 95% confidence interval (CI) 0.59 to 0.74; 8 studies, 1078 participants), which improved PTSD symptoms in 58% of SSRI participants compared with 35% of placebo participants, based on moderate-certainty evidence.  For this outcome we also found evidence of beneficial effect for the noradrenergic and specific serotonergic antidepressant (NaSSA) mirtazapine: (RR 0.45, 95% CI 0.22 to 0.94; 1 study, 26 participants) in 65% of people on mirtazapine compared with 22% of placebo participants, and for the tricyclic antidepressant (TCA) amitriptyline (RR 0.60, 95% CI 0.38 to 0.96; 1 study, 40 participants) in 50% of amitriptyline participants compared with 17% of placebo participants, which improved PTSD symptoms. These outcomes are based on low-certainty evidence. There was however no evidence of beneficial effect for the number of participants who improved with the antipsychotics (RR 0.51, 95% CI 0.16 to 1.67; 2 studies, 43 participants) compared to placebo, based on very low-certainty evidence. For the outcome of treatment withdrawal, we found evidence of a harm for the individual SSRI agents compared with placebo (RR 1.41, 95% CI 1.07 to 1.87; 14 studies, 2399 participants). Withdrawals were also higher for the separate SSRI paroxetine group compared to the placebo group (RR 1.55, 95% CI 1.05 to 2.29; 5 studies, 1101 participants). Nonetheless, the absolute proportion of individuals dropping out from treatment due to adverse events in the SSRI groups was low (9%), based on moderate-certainty evidence. For the rest of the medications compared to placebo, we did not find evidence of harm for individuals dropping out from treatment due to adverse events.

AUTHORS' CONCLUSIONS

The findings of this review support the conclusion that SSRIs improve PTSD symptoms; they are first-line agents for the pharmacotherapy of PTSD, based on moderate-certainty evidence. The NaSSA mirtazapine and the TCA amitriptyline may also improve PTSD symptoms, but this is based on low-certainty evidence. In addition, we found no evidence of benefit for the number of participants who improved following treatment with the antipsychotic group compared to placebo, based on very low-certainty evidence. There remain important gaps in the evidence base, and a continued need for more effective agents in the management of PTSD.

The impact and experience of debriefing for clinical staff following traumatic events in clinical settings: A systematic review

Health care professionals are more frequently exposed to potentially traumatic events than individuals in other professions. Repeated trauma exposure can significantly impact both physical and mental health. In clinical settings, the term "debriefing" refers to a group meeting during which clinical events and decision-making are reviewed and discussed to improve clinical practice. The present review investigated the use of debriefing for clinical staff in clinical settings following exposure to direct and vicarious trauma. We examined whether the use of posttrauma debriefing impacts symptoms of distress and explored how clinical staff experience debriefing; we also investigated the factors that influence this experience. A systematic search of five electronic databases was conducted between August 31 and September 2, 2019. Included articles (N = 13) described the use of debriefing in clinical settings with clinical staff following a traumatic event. We assessed methodological quality and performed a narrative synthesis. Four studies found some evidence of the benefits of debriefing for reducing psychological sequelae to traumatic events. Seven studies commented on factors that clinical staff perceived to be important for the debriefing to feel helpful, including the being given the opportunity for reflection, gaining a shared experience, and having the right peer facilitator. Some evidence suggests that debriefing with staff working in clinical settings can reduce posttraumatic distress symptoms, and subjective evidence suggests that clinical staff members perceive debriefing to be useful. Due to the limited literature, no firm conclusions could be drawn, and further methodologically sound research is required.

The Other Side of the Coin: Nocebo Effects and Psychotherapy

Psychotherapy and placebo have a long history, and both have been shown to have significant and clinically meaningful effects. In the last 100 years and up to today, psychotherapy has been subject to an enduring and often heated debate about its mechanisms and its possible relationship to placebos and their effects. However, there is little awareness of the placebo effects' counterpart-nocebo effects (from Latin "I will harm")-in the context of psychotherapy. Embedded in the controversy of whether psychotherapy and placebo share some unwanted proximity in terms of effects and mechanisms, the question arises which role nocebo effects may play in relation to psychotherapy. By using two examples, this article analyzes and discusses two different kinds of possible associations between psychotherapy and nocebo effects. We close with possibilities of how to prevent the occurrence of nocebo effects in psychotherapy, including some specific recommendations for clinical practice.

Medical models and metaphors for depression

BACKGROUND

The aetiology of depression is not fully understood, which allows many different perspectives on aetiology to be adopted. Researchers and clinicians may be attracted to concepts of aetiology that parallel other diagnoses with which they are familiar. Such parallels may assume the role of informal models or metaphors for depressive disorders. They may even function as informal scientific theories of aetiology, energising research activities by guiding hypothesis generation and organising new knowledge. Parallels between different types of disease may ultimately prove valuable as frameworks supporting the emergence and maturation of new knowledge. However, such models may be counterproductive if their basis, which is likely to lay at least partially in analogy, is unacknowledged or overlooked. This could cause such models to appear more compelling than they really are. Listing examples of situations in which models of depression may arise from, or be strengthened by, parallels to other familiar conditions may increase the accessibility of such models either to criticism or support. However, such a list has not yet appeared in the literature. The present paper was written with the modest goal of stating several examples of models or metaphors for depression.

METHOD

This paper adopted narrative review methods. The intention was not to produce a comprehensive list of such ideas, but rather to identify prominent examples of ways of thinking about depression that may have been invigorated as a result parallels with other types of disease.

RESULTS

Eight possible models are identified: depressive disorders as chemical imbalances (e.g., a presumed or theoretical imbalance of normally balanced neurotransmission in the brain), degenerative conditions (e.g., a brain disease characterised by atrophy of specified brain structures), toxicological syndromes (a result of exposure to a noxious psychological environment), injuries (e.g., externally induced brain damage related to stress), deficiency states (e.g., a serotonin deficiency), an obsolete category (e.g., similar to obsolete terms such as 'consumption' or 'dropsy'), medical mysteries (e.g., a condition poised for a paradigm-shifting breakthrough) or evolutionary vestiges (residual components of once adaptive mechanisms have become maladaptive in modern environments).

CONCLUSIONS

Conceptualisation of depressive disorders may be partially shaped by familiar disease concepts. Analogies of this sort may ultimately be productive (e.g., through generating hypotheses by analogy) or destructive (e.g., by structuring knowledge in incorrect, but intellectually seductive, ways).

Dealing with violent and aggressive patients: at what cost to nurses?

Objectives: To determine the attitudes and experiences of nursing staff in relation to violent and aggressive patients.

Method: A self-administered questionnaire booklet was distributed to 289 nursing staff working in ‘high-risk’ units within two NHS Trusts. In addition to assessing the frequency of violent incidents, the degree of burnout and post-traumatic symptoms experienced were assessed by the inclusion of two standardised measures in the survey, viz, the Maslach Burnout Inventory and the Impact of Event Scale-Revised respectively.

Results: One hundred and fifty six (54%) nurses responded to this survey. Over two-thirds of nurses (72%) had been physically assaulted during the previous two years. The longterm psychological impact of these incidents was not related to whether or not a physical injury was sustained. A positive correlation between burnout and exposure to verbal abuse, threatened assault and violence was demonstrated.

Conclusions: Nurses in these Trusts are exposed to an unacceptable level of violence or aggression from patients, potential implications of which include post-traumatic reactions and burnout. However, nurses are reluctant to report incidents of verbal abuse or threats formally, and they rely upon the support of their colleagues following ‘distressing’ incidents. To protect the wellbeing of their staff, hospital management needs to consider preventative measures, such as training and personal alarms, and improved reporting systems to ensure all incidents are accurately recorded.

Helping youth immediately following war exposure: a randomized controlled trial of a school-based intervention program

This study evaluates a school-based primary prevention intervention designed to promote adolescents' coping in the immediate aftermath of war exposure in Operation Cast Lead. Participants were 179 adolescents from two demographically similar schools in Ashkelon in south Israel. The intervention incorporated two previously proven resilience factors-mobilization of support and self-efficacy. In a repeated measures design, the study assessed pre- to post-test changes in intervention (n=94) and control (n=85) conditions among adolescents exposed to high or low political life events (PLE). Findings showed significant pre-test differences in self-efficacy and psychological symptoms between participants with low and high PLE. For both PLE groups, the intervention strengthened support mobilization and self-efficacy and reduced psychological distress and emotional symptoms. Findings reinforce the importance of offering appropriate evidence-based interventions for school staff to restore security and well-being to adolescents in a crisis context immediately following war. Despite the apparent return to a school routine after war, school staff should be aware of the risk to youth for development of psychological symptoms and disorders, and the need for preventative intervention.

Development of mental health first aid guidelines on how a member of the public can support a person affected by a traumatic event: a Delphi study

BACKGROUND

People who experience traumatic events have an increased risk of developing a range of mental disorders. Appropriate early support from a member of the public, whether a friend, family member, co-worker or volunteer, may help to prevent the onset of a mental disorder or may minimise its severity. However, few people have the knowledge and skills required to assist. Simple guidelines may help members of the public to offer appropriate support when it is needed.

METHODS

Guidelines were developed using the Delphi method to reach consensus in a panel of experts. Experts recruited to the panels included 37 professionals writing, planning or working clinically in the trauma area, and 17 consumer or carer advocates who had been affected by traumatic events. As input for the panels to consider, statements about how to assist someone who has experienced a traumatic event were sourced through a systematic search of both professional and lay literature. These statements were used to develop separate questionnaires about possible ways to assist adults and to assist children, and panel members answered either one questionnaire or both, depending on experience and expertise. The guidelines were written using the items most consistently endorsed by the panels across the three Delphi rounds.

RESULTS

There were 180 items relating to helping adults, of which 65 were accepted, and 155 items relating to helping children, of which 71 were accepted. These statements were used to develop the two sets of guidelines appended to this paper.

CONCLUSIONS

There are a number of actions which may be useful for members of the public when they encounter someone who has experienced a traumatic event, and it is possible that these actions may help prevent the development of some mental health problems in the future. Positive social support, a strong theme in these guidelines, has some evidence for effectiveness in developing mental health problems in people who have experienced traumatic events, but the degree to which it helps has not yet been adequately demonstrated. An evaluation of the effectiveness of these guidelines would be useful in determining their value. These guidelines may be useful to organisations who wish to develop or revise curricula of mental health first aid and trauma intervention training programs and policies. They may also be useful for members of the public who want immediate information about how to assist someone who has experienced a potentially traumatic event.

Do all psychological treatments really work the same in posttraumatic stress disorder?

A recent meta-analysis by Benish, Imel, and Wampold (2008, Clinical Psychology Review, 28, 746-758) concluded that all bona fide treatments are equally effective in posttraumatic stress disorder (PTSD). In contrast, seven other meta-analyses or systematic reviews concluded that there is good evidence that trauma-focused psychological treatments (trauma-focused cognitive behavior therapy and eye movement desensitization and reprocessing) are effective in PTSD; but that treatments that do not focus on the patients' trauma memories or their meanings are either less effective or not yet sufficiently studied. International treatment guidelines therefore recommend trauma-focused psychological treatments as first-line treatments for PTSD. We examine possible reasons for the discrepant conclusions and argue that (1) the selection procedure of the available evidence used in Benish et al.'s (2008)meta-analysis introduces bias, and (2) the analysis and conclusions fail to take into account the need to demonstrate that treatments for PTSD are more effective than natural recovery. Furthermore, significant increases in effect sizes of trauma-focused cognitive behavior therapies over the past two decades contradict the conclusion that content of treatment does not matter. To advance understanding of the optimal treatment for PTSD, we recommend further research into the active mechanisms of therapeutic change, including treatment elements commonly considered to be non-specific. We also recommend transparency in reporting exclusions in meta-analyses and suggest that bona fide treatments should be defined on empirical and theoretical grounds rather than by judgments of the investigators' intent.

Expression of emotion: when it causes trauma and when it helps

The idea that clients should be encouraged to express strong emotion regarding the traumas they have suffered is widely assumed. This article asks whether the empirical literature supports the underlying assumption that emotional expression leads to positive outcomes (better health and dissipation of distress). Studies in which individuals who have been given an opportunity to express emotions about past traumas are compared with subjects placed in appropriate control conditions are reviewed. The empirical literature suggests that eliciting emotion is harmful when it is not associated with reappraisal of past trauma, but helpful when the reappraisal occurs. The following guideline emerges: if trauma is to be revisited, it should be accompanied by reappraisal. Since this is sometimes difficult to engineer, alternative approaches for working with victims of trauma, not involving revisiting the trauma, are offered. Additionally, it is suggested that it can be helpful to identify the nature of the problem arising from the traumatic experience and then provide therapeutic intervention that addresses the problem.

Emotion Elicits the Social Sharing of Emotion: Theory and Empirical Review

This review demonstrates that an individualist view of emotion and regulation is untenable. First, I question the plausibility of a developmental shift away from social interdependency in emotion regulation. Second, I show that there are multiple reasons for emotional experiences in adults to elicit a process of social sharing of emotion, and I review the supporting evidence. Third, I look at effects that emotion sharing entails at the interpersonal and at the collective levels. Fourth, I examine the contribution of emotional sharing to emotion regulation together with the relevant empirical evidence. Finally, the various functions that the social sharing of emotion fulfills are reviewed and the relevance of the social sharing of emotion for emotion scientists is discussed.

An Evaluation of a Police Debriefing Programme: Outcomes for Police Officers Five Years after a Police Shooting

To evaluate the effectiveness of a debriefing programme to reduce traumatic stress in a police organisation, officers involved in a shooting were surveyed by questionnaire, five years after the event. The results showed that 79 per cent of 57 officers had not received debriefing, despite its mandatory status. Those who had received debriefing had higher post-traumatic stress disorder (PTSD) scores; however, regression of PTSD and health scores, on stress perceptions, social support, other trauma, and debriefing, showed that debriefing had no significant effect. These results support those of other controlled studies suggesting that debriefing does not mitigate PTSD and may exacerbate symptoms. A number of limitations of the present study are discussed in terms of suggestions for urgent evaluation of such programs in organisational settings.

Efficacy of a school-based primary prevention program for coping with exposure to political violence

A paradigm conceptualizing resilience as factors moderating between political violence exposure and psychological distress administered in a 7-year research project yielded a profile of factors promoting Israeli children's coping in conflict conditions. Three factors — social support mobilization, selfefficacy, and meaning attribution — were incorporated into a school-based primary intervention program. In a repeated measures design, the study assessed pre to post-test modifications in the three resilience factors and psychological distress in a primary and control intervention condition and the interaction of actual political violence exposure on distress reduction. Results validated modification only of the mobilization of support factor, but nonetheless confirmed the primary program's efficacy in moderating psychological distress particularly among children with low actual political violence exposure, who showed greater distress increases in the control condition. Findings reinforce the educational system's role in promoting resilience among children in conflict environments.

A randomised controlled trial of group debriefing

There has never been published a randomised controlled trial of group debriefing. In this study we employed an analogue study with students to conduct the first such trial. Sixty-four participants were shown a stressful video of paramedics attending to injured and dead victims of a road traffic accident. Half the participants were subsequently debriefed and half were provided with tea and biscuits and allowed to talk amongst themselves. A 1 month follow-up was administered. It was found that, while the video was rated as distressing, there were no significant differences between the debriefed and non-debriefed groups on measures of affective distress and trauma symptoms. Those who were debriefed later recalled having wanted to talk more to someone about the video than those who were not debriefed. It is suggested that cognitive dissonance may explain this result.

Promoting mental health following the London bombings: a screen and treat approach

Following the 2005 London bombings, a novel public health program was instituted to address the mental health needs of survivors. In this article, the authors describe the rationale for the program, characteristics of individuals assessed within the program, and preliminary outcome data. In addition to validated screening instruments and routine service usage data, standardized questionnaire outcome measures were collected. Seventy-one percent of individuals screened positive for a mental disorder. Of those receiving a more detailed clinical assessment, PTSD was the predominant diagnosis. Preliminary outcome data on 82 patients revealed large effect sizes for treatment comparable to those previously obtained in randomized controlled trials. The program succeeded in its aim of generating many more referrals of affected individuals than came through normal referral channels.

Pharmacotherapy for post traumatic stress disorder (PTSD)

BACKGROUND

Post traumatic stress disorder (PTSD) is a prevalent and disabling disorder. Evidence that PTSD is characterised by specific psychobiological dysfunctions has contributed to a growing interest in the use of medication in its treatment.

OBJECTIVES

To assess the effects of medication for post traumatic stress disorder.

SEARCH STRATEGY

We searched the Cochrane Depression, Anxiety and Neurosis Group specialised register (CCDANCTR-Studies) on 18 August 2005, the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library issue 4, 2004), MEDLINE (January 1966 to December 2004), PsycINFO (1966 to 2004), and the National PTSD Center Pilots database. Reference lists of retrieved articles were searched for additional studies.

SELECTION CRITERIA

All randomised controlled trials (RCTs) of pharmacotherapy for PTSD.

DATA COLLECTION AND ANALYSIS

Two raters independently assessed RCTs for inclusion in the review, collated trial data, and assessed trial quality. Investigators were contacted to obtain missing data. Summary statistics were stratified by medication class, and by medication agent for the selective serotonin reuptake inhibitors (SSRIs). Dichotomous and continuous measures were calculated using a random effects model, heterogeneity was assessed, and subgroup/sensitivity analyses were undertaken.

MAIN RESULTS

35 short-term (14 weeks or less) RCTs were included in the analysis (4597 participants). Symptom severity for 17 trials was significantly reduced in the medication groups, relative to placebo (weighted mean difference -5.76, 95% confidence intervals (CI) -8.16 to -3.36, number of participants (N) = 2507). Similarly, summary statistics for responder status from 13 trials demonstrated overall superiority of a variety of medication agents to placebo (relative risk 1.49, 95% CI 1.28 to 1.73, number needed to treat = 4.85, 95% CI 3.85 to 6.25, N = 1272). Medication and placebo response occurred in 59.1% (N = 644) and 38.5% (628) of patients, respectively. Of the medication classes, evidence of treatment efficacy was most convincing for the SSRIs. Medication was superior to placebo in reducing the severity of PTSD symptom clusters, comorbid depression and disability. Medication was also less well tolerated than placebo. A narrative review of 3 maintenance trials suggested that long term medication may be required in treating PTSD.

AUTHORS' CONCLUSIONS

Medication treatments can be effective in treating PTSD, acting to reduce its core symptoms, as well as associated depression and disability. The findings of this review support the status of SSRIs as first line agents in the pharmacotherapy of PTSD, as well as their value in long-term treatment. However, there remain important gaps in the evidence base, and a continued need for more effective agents in the management of PTSD.

Description of an early intervention to prevent substance abuse and psychopathology in recent rape victims

Approximately 683,000 adult women are raped each year. Only one in seven of these victims report the assault to police and receive forensic exams and other professional services. For many rape victims, this may be the only professional contact with service providers; however these services are typically limited to evidence collection and prophylactic STD treatment. Yet this exam also presents a unique opportunity for a preventive intervention to help prepare women to cope with potential stress related to rape-exam procedures and to address potential post rape psycho-pathology. This article reviews psychological interventions for trauma victims used in the acute post rape time frame and provides data from an ongoing clinical trial that evaluates delivery of a preventive intervention for victims presenting for forensic rape exams.

Risk factor effect sizes in PTSD: what this means for intervention

This paper reviews evidence concerning the major risk factors for posttraumatic stress disorder. Although there are a number of consistent risk factors, their effects tend to be small and to vary according to the nature of the study. This suggests that they are not well suited to identifying individuals who require early intervention following a traumatic event. In contrast, methods based on symptom reports offer a much more sensitive and practicable approach to screening. A recent instrument, the Trauma Screening Questionnaire, is brief, simple to administer, and highly efficient at identifying survivors in need of intervention.

[Secondary prevention for police officers involved in job-related psychologically stressful or traumatic situations]

OBJECTIVES

Police officers are at high risk of being exposed to psychologically straining situations and potentially psychotraumatic experiences. In this article, such situations are exemplified and categorized, and the role and significance of secondary prevention following traumatic experiences is discussed.

METHODS

From 1994 to 2003, 649 police officers received secondary prevention after being involved in a total of 250 potentially traumatic or psychologically stressful incidents. Psychological support was provided by teams of specially trained professionals in the acute phase after the incident following careful psychological evaluation. In a retrospective evaluation, the diagnoses obtained were analyzed with regard to sex and age and correlated with the severity of the incident. Three clusters of potentially traumatic situations were formed: (1) Employment of fire-arms with danger for the officer, (2) Standard situations including violence towards a third party, (3) Suicide or attempted suicide of a police officer.

RESULTS

Police officers who experienced events assigned to cluster (1), comprising situations with considerable traumatic potential, had the highest incidence of posttraumatic stress disorder (PTSD) or other mental illness. Compared to male officers, females were more often diagnosed with other mental illness, whereas males had a higher incidence of PTSD. Cluster (2), which comprised situations of an officer's daily professional life, was not associated with an increased risk of mental illness. Officers were apparently capable of coping with situations considered psychologically straining for the general public without detectable evidence of a traumatic reaction. In cluster (3), which reflects the most dramatic interference with team relations, other forms of mental illness were diagnosed at a higher incidence.

[Efficiency of psychological debriefing in preventing post-traumatic stress disorders]

BACKGROUND

Traumatic events are frequently followed by an acute stress reaction that may develop into a post-traumatic stress disorder. An intervention called psychological debriefing has been proposed to prevent these disorders. Although this method is widely used at present, its preventive effect is controversial. This article consist in a review of the studies which evaluated psychological debriefing efficiency in the prevention of post-traumatic stress disorder and associated disorders in adults.

METHOD

We carried out a bibliographical search on MEDLINE (1966-2001), PASCAL (1987-2001), EMBASE (1988-2001), FRANCIS (1984-2001) and SCIENCEDIRECT (1967-2001). The key words were posttraumatic stress disorder, debriefing, treatment, psychological follow up, and prevention. We selected the studies with the following criteria: adults, one psychological debriefing session in the Month following the event, inclusion of a control group, more than 20 persons per group and evaluation of psychological disorders with standardized instruments more than one Month after the trauma.

RESULTS

Twenty nine studies were identified and 8 selected. Four studies did not show any intervention effect, 3 suggested a negative intervention effect, and 1 suggested a positive effect on anxiety, depressive symptoms and alcohol dependence.

CONCLUSION

Psychological debriefing implies re-exposure through memory processes to the trauma, which can interfere with the natural course of adjustment and recovery. Several Authors have suggested that psychological debriefing may delay the diagnosis and thus the early treatment of post-traumatic stress disorder. Psychological debriefing may not be appropriate to all victims of every type of incident or trauma. We discuss the intervention and its design. This review did not show evidence for psychological debriefing efficiency, as a unique session, in the prevention of posttraumatic reactions. The design and the objectives may be re-examined. Further evaluations following rigorous methods are warranted.

Review of child and adolescent refugee mental health

OBJECTIVE

To review stressful experiences and stress reactions among child and adolescent refugees, as well as interventions and ethical considerations in research and clinical work, within the framework of the chronological experiences of child refugees; namely, the phases of preflight, flight, and resettlement. Highlighted are special refugee populations such as unaccompanied minors, asylum seekers, and former child soldiers. Pertinent medical findings are summarized.

METHOD

The authors reviewed articles from 1990 to 2003 addressing the topics above. Literature was gathered from databases including PsycINFO, Medline, and SocioFile. Pertinent earlier papers and those from other disciplines cited in database-identified articles were also included.

RESULTS

Child and adolescent refugees suffer from significant conflict-related exposures. Reactions to stress may be mediated by coping strategies, belief systems, and social relations.

CONCLUSIONS

More research is needed on interventions, specifically on efficacy and cultural relevance. Interventions that have an impact on multiple ecological levels need further development and evaluation.

An acute post-rape intervention to prevent substance use and abuse

The trauma of rape is routinely associated with extreme acute distress. Such peri-event anxiety increases risk of developing psychopathology and substance use or abuse post-rape, with the degree of initial distress positively predicting future problems. Unfortunately, the nature of post-rape forensic evidence collection procedures may exacerbate initial distress, thereby potentiating post-rape negative emotional sequelae. Consequently, substance use may increase in an effort to ameliorate this distress. To address this, a two-part video intervention was developed for use in acute post-rape time frames to (a) minimize anxiety during forensic rape examinations, thereby reducing risk of future emotional problems, and (b) prevent increased post-rape substance use and abuse. Pilot study data with 124 rape victims indicated that the low-cost, easily administered intervention was effective in reducing risk of marijuana abuse at 6 weeks. Nonstatistically significant trends also were evident for reduced marijuana use. Trends were also noted in favor of the intervention in the subgroup of women who were actively using substances pre-rape (among pre-rape alcohol users, 28% viewers vs. 43% nonviewers met criteria for post-rape alcohol abuse; among pre-rape marijuana users, the rates of post-marijuana use were 17% vs. 43%).

Stress debriefing after childbirth: a randomised controlled trial

OBJECTIVE

To test whether critical incident stress debriefing after childbirth reduces the incidence of postnatal psychological disorders.

DESIGN

Randomised single-blind controlled trial stratified for parity and delivery mode.

SETTING

Two large maternity hospitals in Perth.

PARTICIPANTS

1745 women who delivered healthy term infants between April 1996 and December 1997 (875 allocated to intervention and 870 to control group).

INTERVENTION

An individual, standardised debriefing session based on the principles of critical incident stress debriefing carried out within 72 hours of delivery.

MAIN OUTCOME MEASURES

Diagnosis of stress disorders or depression in the 12 months postpartum, using structured psychological interview and criteria of the Diagnostic and statistical manual of mental disorders, 4th edition.

RESULTS

Follow-up information was available for 1730 women (99.1%), 482 of whom underwent psychological interview. There were no significant differences between control and intervention groups in scores on Impact of Events or Edinburgh Postnatal Depression Scales at 2, 6 or 12 months postpartum, or in proportions of women who met diagnostic criteria for a stress disorder (intervention, 0.6% v control, 0.8%; P = 0.58) or major or minor depression (intervention, 17.8% v control, 18.2%; relative risk [95% CI], 0.99 [0.87-1.11]) during the postpartum year. Nor were there differences in median time to onset of depression (intervention, 6 [interquartile range, 4-9] weeks v control, 4 [3-8] weeks; P = 0.84), or duration of depression (intervention, 24 [12-46] weeks v control, 22 [10-52] weeks; P = 0.98).

CONCLUSIONS

There is a high prevalence of depression in women during the first year after childbirth. A session of midwife-led, critical incident stress debriefing was not effective in preventing postnatal psychological disorders, but had no adverse effects.

Post-traumatic stress disorder in women: current concepts and treatments

In the US, 13% of women develop post-traumatic stress disorder (PTSD) during their lifetime. An accurate diagnosis of PTSD requires screening for trauma and symptoms of PTSD. Current research in the neurobiologic and psychologic responses to traumatic stress supports the use of pharmacologic and psychosocial interventions. Selective serotonin reuptake inhibitors are the current first-line pharmacotherapy. Efficacious psychosocial interventions include exposure therapy and cognitive processing therapy.

An evaluation of patient satisfaction with an information leaflet for trauma survivors

A new leaflet that provided information about posttraumatic reactions and how to deal with them was distributed within 14 days of attendance at the Accident and Emergency Department (ED), Aberdeen Royal Infirmary, to a heterogeneous sample of trauma patients (N = 222). An evaluation form to assess satisfaction with the leaflet was also mailed with the leaflet. A sample of 98 (44%) of the initial patient group responded, and 96% of them reported the leaflet as either very helpful or helpful. Satisfaction with the leaflet was not affected by age, by gender, or by the type of trauma encountered. Overall, the findings confirmed that such a leaflet is well received by trauma patients attending an ED.

Posttraumatic stress disorder after pre-eclampsia: an exploratory study

Information about the psychological sequelae of pre-eclampsia (PE) is scarce. Post-traumatic stress disorder (PTSD) may develop after exposure to a stress condition. This study explored whether PE predisposes to PTSD in patients and their partners. Primiparas with a recent history of preterm PE (n=18), preterm birth (PT; n=29), term PE (n=23), or uneventful term birth (C; n=43), and most of their partners completed questionnaires measuring PTSD, depression and related psychological factors. About one-fourth of patients developed PTSD after preterm PE as well as after PT. It occurred in 17% after term PE and in none of the control subjects. A substantial minority of partners was also affected. PTSD symptoms were strongly related to individual psychological characteristics (peritraumatic dissociation, negative interpretations of symptoms, and thought suppression) rather than to objective indicators of condition-severity. The data suggest that PE predisposes to PTSD, primarily but not exclusively resulting from concomitant preterm birth.

Effectiveness of psychological debriefing

OBJECTIVE

To identify literature concerning the effectiveness of psychological debriefing (PD) and analyse results according to different criteria of success and different uses of the intervention format.

METHOD

Literature search was made in databases PubMed, PsycInfo and Psychlit. Twenty-five studies were selected for a thorough description. Forty-two studies provided additional information.

RESULTS

Results indicate that, in general, debriefing does not prevent psychiatric disorders or mitigate the effects of traumatic stress, even though people generally find the intervention helpful in the process of recovering from traumatic stress. The intervention holds potential as a screening procedure, and there may be economic arguments for continued use. When used with adherence to traditional descriptions of treatment group, events, group format, leadership and time spent, a preventive effect emerges. No tendency according to timing was found.

CONCLUSION

Current uses of PD are problematic. The concept needs to be redefined, and the scope of application must be revised. The objectives for use need to be clarified.

Comorbidity of post-traumatic stress disorder and chronic pain: implications for clinical and forensic assessment

A summary of the current state of science is presented with reference to post-traumatic stress disorder (PTSD) and pain. Historical development of the diagnosis, current nosology, epidemiology, pathophysiology, and controversies are discussed. Issues of evaluation are reviewed, with specific reference to forensic assessment. Treatment outcome studies are briefly reviewed, with a review of currently accepted treatment interventions, including pharmacologic and behavioral modalities. An emphasis is placed on an integrated treatment plan in which chronic pain and PTSD both are present.

Critical incident stress debriefing following traumatic life experiences

This study was designed to explore the use of critical incident stress debriefing as a therapeutic intervention following traumatic life events. A case study approach was used to allow the researchers to adopt a more flexible and overtly involved stance. Initial contact took place 24 h following the traumatic life experiences of three women. Critical incident stress debriefing was provided and data were collected and recorded within an ethical framework. Six months following the traumatic life experiences the women were interviewed again to explore their perceptions of the intervention that was provided. The results demonstrated positive outcomes. The women concluded that the debriefing intervention provided a safe forum for them to explore their needs, process their experiences and create constructive narratives. A carefully constructed critical incident stress debriefing intervention was used within the context of its objectives and acknowledged limitations. The study was small and generalizations cannot be made to other individuals who experience similar tragedies. Nevertheless, evidence from previous research coupled with the findings from this study suggests that mental health nurses might benefit from being educated and trained in critical incident stress debriefing. Further research needs to be carried out to explore the use of different models of stress debriefing applied to special circumstances. The goal of such interventions should be to alleviate symptoms and to prevent the development of a full-blown post-traumatic stress disorder.

Collaborative interventions for physically injured trauma survivors: a pilot randomized effectiveness trial

Posttraumatic behavioral and emotional disturbances occur frequently among physically injured hospitalized trauma survivors. This investigation was a pilot randomized effectiveness trial of a 4-month collaborative care intervention for injured motor vehicle crash and assault victims. As surgical inpatients, intervention subjects (N=16) were assigned to a trauma support specialist who provided counseling, consulted with surgical and primary care providers, and attempted postdischarge care coordination. Control subjects (N=18) received usual posttraumatic care. For all participants, posttraumatic stress disorder (PTSD) and depressive symptoms, episodic alcohol intoxication, and functional limitations were evaluated during the hospitalization and 1 and 4 months postinjury. Study logs and field notes revealed that over 75% of intervention activity occurred in the first month after the trauma. One-month post-trauma intervention subjects when compared to controls demonstrated statistically significant decreases in PTSD symptoms as well as a reduction in depressive symptoms. However, at the 4-month assessment, intervention subjects evidenced no significant improvements in PTSD and depressive symptoms, episodic alcohol intoxication, or functional limitations. Future larger scale trials of stepped collaborative care interventions for physically injured trauma survivors are recommended.

Effect of timing of critical incident stress debriefing (CISD) on posttraumatic symptoms

Seventy-seven civilian employees who were victims of robbery were randomly assigned to either an immediate (< 10 hr) or delayed (> 48 hr) debriefing group, using the J. Mitchell (1983) CISD protocol. Scores on the Posttraumatic Stress Diagnostic Scale were obtained at 4 time intervals: debrief, 2 and 4 days post-debrief, and 2 weeks postrobbery. The number and severity of symptoms did not differ at debrief, but were lower for the immediate than for the delayed group at each subsequent time interval. The number and severity of symptoms declined across time intervals; however, although this reduction was pronounced for the immediate group it was minimal for the delayed group. The results supported use of immediate debriefing with this type of incident and victim.
