The Prevalence of Adverse Childhood Experiences Among Children and Adolescents Who Display Harmful Sexual Behaviour: A Review of the Existing Research.

There is no systematic review focusing on the prevalence of adverse childhood experiences (ACEs) among children and adolescents who display harmful sexual behaviour (HSB). This study addresses this gap to further our understanding of the aetiology of HSB among children and adolescents. The full text of 87 articles was retrieved and assessed for eligibility, following which 10 articles were deemed relevant for inclusion in the review. These 10 studies were then subjected to quality assessment, data extraction and synthesis. The present review included only studies that used data pertaining to both males and females, and some studies provided a comparison between males and females. There were higher rates of sexual victimisation among females who display HSB. Additionally, child sexual abuse perpetrated by female caregivers is likely to be higher than most of the existing body of research suggests. The findings of the present review corroborate many of the hypotheses discussed in the introduction, emphasising that children and adolescents who display HSB are more likely to have come from backgrounds of trauma, signaling the importance of multi-agency responses, early intervention and the importance of protective factors.

Extreme sport as an intervention for physically injured military veterans: the example of competitive motorsport.

PURPOSE: Physically or psychologically injured military veterans are motivated and benefited by physical activity or sport that may involve high levels of achievement. The aim of this study was to provide an in-depth insight into the impact of Competitive Motorsport (CM) on physically injured/disabled veterans' subjective well-being and in turn determine if it improves the quality of their lives. METHODS: This is a qualitative study. Two sets of semi-structured interviews were conducted with 14 male British military veterans including a 6-month follow-up. All participants were subjected to a permanent, moderate or severe, physical injury/disability. Data were analysed in accordance with the principles of Thematic Analysis. RESULTS/CONCLUSIONS: Five key elements (familiar environment, team spirit, adrenaline rush, competition and equality) made CM a unique experience for physically injured/disabled veterans. Various psychological and physical benefits were found, including an increased sense of accomplishment, opportunity to socialise in a non-clinical environment, embracement of body image and adoption of a healthier lifestyle. Since physical activity and sport are among growing research on alternative interventions for military veterans, they deserve serious consideration as part of the treatment regimens and rehabilitation programmes to improve physically inured/disabled veterans' physical and mental health.Implications for RehabilitationCompetitive Motorsport is an effective means of improving physical health and subjective well-being of physically injured/disabled military veterans.Multiple perceived psychological and physical benefits were identified over time, including motivation for living, embracement of body image and adoption of a healthier lifestyle.Competitive Motorsport deserves consideration as part of the treatment regimens and rehabilitation programmes to improve physically injured/disabled veterans' physical and mental health while facilitating transition to civilian life.

Evaluating narrative exposure therapy for post-traumatic stress disorder and depression symptoms: A meta-analysis of the evidence base.

Narrative exposure therapy (NET) is an intervention for trauma spectrum disorders. Originally developed to treat refugee populations, NET has since been tested for efficacy across different settings. In this review, the NET evidence base is examined through a retrieval, synthesis and appraisal of randomized controlled trials (RCTs) published since 2002. Two independent reviewers (S. R. and N. S.) searched online databases including EMBASE, PsycINFO and PubMed. Twenty-four RCTs were selected for a meta-analysis of three outcomes: post-traumatic stress disorder (PTSD) diagnosis and PTSD and depression symptoms. All outcomes were analysed at short-term (3-4 months), midterm (6-7 months) and long-term (≥12 months) data points. A random-effects model was applied to yield standardized mean differences (SMDs) and odds ratios (ORs) as indicators of NET treatment effect. Subgroup analyses for type of trauma and type of control groups were conducted to examine potential heterogeneity. For the NET group, moderate effect sizes for PTSD symptom severity were observed at midterm and long term and at midterm for depression symptom severity. The number of PTSD diagnoses decreased significantly in the short term for the NET condition, but this was not sustained at the long term. Caution must be exercised when interpreting these results due to high heterogeneity estimates and low quality of evidence across trials. Potential small-study effects further complicate the interpretation of the findings. Recommendations are made for augmenting statistical significance research with qualitative analyses of NET efficacy to better inform clinical practice.

Activity or connectivity? A randomized controlled feasibility study evaluating neurofeedback training in Huntington's disease.

Non-invasive methods, such as neurofeedback training, could support cognitive symptom management in Huntington's disease by targeting brain regions whose function is impaired. The aim of our single-blind, sham-controlled study was to collect rigorous evidence regarding the feasibility of neurofeedback training in Huntington's disease by examining two different methods, activity and connectivity real-time functional MRI neurofeedback training. Thirty-two Huntington's disease gene-carriers completed 16 runs of neurofeedback training, using an optimized real-time functional MRI protocol. Participants were randomized into four groups, two treatment groups, one receiving neurofeedback derived from the activity of the supplementary motor area, and another receiving neurofeedback based on the correlation of supplementary motor area and left striatum activity (connectivity neurofeedback training), and two sham control groups, matched to each of the treatment groups. We examined differences between the groups during neurofeedback training sessions and after training at follow-up sessions. Transfer of training was measured by measuring the participants' ability to upregulate neurofeedback training target levels without feedback (near transfer), as well as by examining change in objective, a priori defined, behavioural measures of cognitive and psychomotor function (far transfer) before and at 2 months after training. We found that the treatment group had significantly higher neurofeedback training target levels during the training sessions compared to the control group. However, we did not find robust evidence of better transfer in the treatment group compared to controls, or a difference between the two neurofeedback training methods. We also did not find evidence in support of a relationship between change in cognitive and psychomotor function and learning success. We conclude that although there is evidence that neurofeedback training can be used to guide participants to regulate the activity and connectivity of specific regions in the brain, evidence regarding transfer of learning and clinical benefit was not robust.

Psychological support for orthognathic patients: Who is doing what?

OBJECTIVE: To investigate: (1) orthodontists' training experience in the psychological assessment of orthognathic patients and their wish for training/further training; (2) the availability of psychological support, referral patterns and outcomes after referral; (3) and adverse incidents prompting orthodontists to refer patients for psychological assessment. DESIGN: Prospective cross-sectional study. METHODS: A 25-item questionnaire was designed to investigate the above mentioned aims. After a pilot study, the questionnaire was distributed to all members of the Consultant Orthodontist Group, British Orthodontic Society. RESULTS: Based on a 29.1% response rate (n = 102), 76.5% of respondents had undertaken training in identifying orthognathic patients who may benefit from psychological assessment. However, 90.2% favoured further training. All respondents believed that some orthognathic patients would benefit from referral; however, 31.3% of units referred no patients at all, mostly due to limited/no access (66.7%). Most referrals (68.9%) were to psychiatrists/psychologists with dentofacial deformity expertise, with 28.9% of units having such services onsite (14 different units). Psychological referrals had potentially useful outcomes, with 36.4% of respondents sometimes changing treatment plans following referral. Clinical incidents were experienced by 35.1% of respondents, prompting referral of patients for psychological assessment; such incidents included patient suicides (n = 4). CONCLUSION: Most respondents had trained in psychological assessment of orthognathic patients; however there was a large demand for further training. Clinicians value the psychological services available; however, limited availability may affect referrals for some respondents. Adverse incidents are of real concern and highlight the need to ensure that training and resources are provided to support orthognathic patients and teams.

Validation and psychometric properties of the Arabic psychological well-being post-traumatic changes questionnaire

Psychological Well-Being Post-Traumatic Changes Questionnaire (PWB-PTCQ) is an instrument for measuring positive changes after trauma that has shown reasonable psychometric properties in its original version in English. The aim of this study was to translate and validate the psychometric properties of an Arabic Psychological Well-Being Post-Traumatic Changes Questionnaire (A-PWB-PTCQ). A descriptive correlational design was used to conduct the study among 357 participants sampled from the Saudi population. Participants reported different traumatic events ranged between 59.5 % for sudden death of close person to 23.3% assault or attempted sexual assault incidents. The A-PWB-PTCQ demonstrated excellent internal consistency at 0.93 and test-retest reliability at 0.92. All inter-item and item-to-total correlations for the PWB-PTCQ scale were above the recommended criteria of 0.30. The A-PWB-PTCQ also showed a significant negative correlation with the Posttraumatic Diagnostic Scale for DSM-5 (PDS-5) (-0.46, p <.001), and those with clinical levels of PTSD had significantly lower scores on the A-PWB-PTCQ (t= 7.62, p <.001) than individuals with subclinical levels of PTSD. The A-PWB-PTCQ was found to be a valid and reliable instrument for measuring the Psychological Well-Being Post-Traumatic Changes among the Arabic population

Experience of Identity Change in People Who Reported a Diagnosis of Multiple Sclerosis: A Qualitative Inquiry.

BACKGROUND: A diagnosis of multiple sclerosis (MS) can lead to changes to a person's sense of self. The aim of this study was to investigate the subjective experience of identity change and subsequent adjustment to MS. METHODS: Semistructured interviews were conducted with 16 people who reported having MS. Interviews were analyzed using thematic analysis. RESULTS: In the early stages of disease progression, participants wanted to compartmentalize the disease. Over time, through reflected self-appraisals, brought about by increasing symptoms and changed relationships with others, the disease became a part of participants' self-identity. CONCLUSIONS: For people with MS, incorporating and accepting the disease as part of their self-identity can have positive implications for seeking and receiving support.

National British Orthodontic Society (BOS) Orthognathic Audit 2017-2018.

OBJECTIVE: To carry out a UK national clinical audit of orthognathic acceptance criteria and information provided to orthognathic patients before treatment. DESIGN: National clinical audit. SETTING: Data collected using Bristol Online Surveys. PARTICIPANTS: Sixty-nine UK hospital orthodontic departments submitted data. METHODS: Data were collected at two time points using Bristol Online Surveys over a period of 12 months. These were before treatment at the first multidisciplinary clinic (MDT) and immediately after surgery. The data collected included: Index of Orthognathic Functional Treatment Need (IOFTN); Index of Orthodontic Treatment Need (IOTN); age; previous orthodontic treatment; attendance at an MDT; treatment times; and information provision. RESULTS: Eighty-five units agreed to take part in the audit with 69 submitting data, giving a response rate of 81%. The data from 3404 patients were uploaded, 2263 before treatment and 1141 immediately after surgery. Of patients, 91.07% had an IOFTN score of 4 or 5 and 88.73% had an IOTN score of 4 or 5. The mean age at the first MDT was 22 years in the first cohort and 21 years and 4 months in the second immediate post-surgery cohort. Of patients, 37.93% had undergone some form of previous orthodontic treatment, but only 0.28% had undergone previous orthognathic treatment; 96.93% had an MDT confirm that orthodontic treatment by itself was insufficient to adequately correct their functional symptoms. The average treatment time from bond up to surgery was 2 years and 6 months. With respect to information provision, patients received information from a number of sources, principally the British Orthodontic Society (BOS) patient information leaflets and the BOS website Your Jaw Surgery. CONCLUSIONS: In the UK, the majority of orthognathic cases fulfil the criteria for acceptance for NHS-funded orthognathic treatment, as outlined by the Chief Dental Officer's interim guidance on orthognathic treatment. This suggests any prior approval process would not be a good use of NHS resources in the commissioning of orthognathic treatment.

Is visual imagery ability higher for orthodontic students than those in other disciplines? A cross-sectional questionnaire-based study.

OBJECTIVE: To investigate the effect visual imagery may have on career choice among current university students across a range of subjects and disciplines. SETTING: University College London (UCL), UK. DESIGN: Cross-sectional questionnaire-based study. PARTICIPANTS: The study compared four main groups of UCL students: current students at the Slade School of Fine Art; UCL Eastman Dental Institute; UCL Bartlett School of Architecture; and the Faculty of Laws. METHOD: A questionnaire based on the Vividness of Visual Imagery Questionnaire (VVIQ) was distributed along with questions regarding demographic information. RESULTS: There were no significant differences between the VVIQ scores across the four included Schools/Faculty: The Slade School of Fine Art; UCL Bartlett School of Architecture; Faculty of Laws; and UCL Eastman Dental Institute, F(3,219) = 2.160, P = 0.094. There were also no significant differences in the scores for the Eastman (M = 60.21, SD = 13.58) and the three other Schools/Faculty (M = 62.87, SD = 10.96); t(-1.317) = 221, P = 0.189, and no significant difference in the scores for the Orthodontic students (M = 60.80, SD = 13.39) and the remaining other included students (M = 61.44, SD = 9.68); t(-0.232) = 221, P = 0.817. Aphantasia was uncommon in this sample, with a prevalence of 0.9%. A positive correlation was found between age group and total VVIQ score, with older participants scoring higher on the VVIQ. Women were significantly more likely to say that their ability to visualise had affected their career choice than male respondents. CONCLUSIONS: There were no significant differences between the VVIQ scores across the four included Schools/Faculty. Visual imagery ability did not differ in dental or orthodontic students in comparison to other student groups. Further work is needed to replicate these findings in more diverse samples.

A comparative study to investigate the effect of orthodontic treatment on the uniqueness of the human anterior dentition.

AIM: The human dentition contains many features which can be used to identify an individual from the dentition or from bite marks created and bite mark evidence may be used to link a suspect to a crime. The aim of this research was to investigate the effect of orthodontic treatment on the uniqueness of the human anterior dentition by comparison of the number of dental shape matches between pre- and post-treatment dental casts for a group of patients who have undergone orthodontic treatment (dental braces) to improve the alignment of their teeth. METHOD: This comparative study utilised pre- and post-orthodontic treatment dental casts from 36 patients. The dental casts were scanned and the anterior 6 teeth landmarked with 24 landmarks in total. The dental casts were divided into 4 groups: pre-orthodontic upper jaw (maxillary) and lower jaw (mandibular) and post-orthodontic maxillary and mandibular. Partial and full Procrustes analyses were undertaken to investigate the similarity between dental casts within each group and whether any of the comparisons were similar enough to be classified as a match. A landmarking repeatability study performed on a set of digitised dental casts determined the error of the landmarking procedure and allowed a proposed match threshold to be established. RESULTS: Orthodontic treatment reduced the uniqueness, and increased the similarity, between dentitions, as evidenced by a reduction in the maximum partial Procrustes distances in the post-orthodontic dental cast groups. None of the dental cast comparisons in the pre- or post-orthodontic maxillary or mandibular groups were classified as a match with the partial Procrustes analysis. However, many false positive matches (between 35 and 61) were identified within the post-orthodontic maxillary and mandibular groups using the full Procrustes analysis. CONCLUSIONS: Orthodontic treatment reduced the uniqueness of the human anterior dentition between different patients. There were no matches identified with the partial Procrustes analysis, but a large number of false positive matches were identified using the full Procrustes analysis. It is therefore proposed that full Procrustes analysis is unsuitable for this type of work and that only partial Procrustes analysis should be utilised.

Social Identity in People with Multiple Sclerosis: An Examination of Family Identity and Mood.

BACKGROUND: Mood disorders are highly prevalent in people with multiple sclerosis (MS). MS causes changes to a person's sense of self. The Social Identity Model of Identity Change posits that group membership can have a positive effect on mood during identity change. The family is a social group implicated in adjustment to MS. The objectives of this study were to investigate whether family identity can predict mood in people with MS and to test whether this prediction was mediated by social support and connectedness to others. METHODS: This cross-sectional survey of 195 participants comprised measures of family identity, family social support, connectedness to others, and mood. RESULTS: Family identity predicted mood both directly and indirectly through parallel mediators of family social support and connectedness to others. CONCLUSIONS: Family identity predicted mood as posited by the Social Identity Model of Identity Change. Involving the family in adjustment to MS could reduce low mood.

Occlusal outcomes in combined orthodontic and orthognathic treatment.

OBJECTIVE: To investigate the treatment outcome in terms of the malocclusion features and the changes in the occlusion of patients undergoing orthodontic/orthognathic treatment using the Peer Assessment Rating (PAR) and the Index of Complexity, Outcome and Need (ICON) and to test the application of the Index of Orthognathic Functional Treatment Need (IOFTN) on this sample as a measure of orthognathic pre-treatment need. DESIGN: Retrospective longitudinal cohort study. SETTING: The orthodontic department at the Eastman Dental Hospital. MATERIAL AND METHODS: The study models of a sample of 100 orthodontic/orthognathic patients who were treated at the Eastman Dental Hospital were measured using the PAR index and ICON at three stages: pre-treatment, pre-surgery and at debond. Treatment need was assessed by measuring IOTN and IOFTN using start study models. RESULTS: 99% of the sample showed an improvement in PAR score, with 82% of the sample being greatly improved. ICON showed that 95% of the sample had an improvement of different degrees with 5% being not improved or worse. The IOFTN qualified 97% of the patients for orthognathic treatment when used retrospectively on the sample while the DHC of IOTN qualified the whole sample for orthodontic treatment. CONCLUSIONS: Orthodontic/orthognathic treatment showed improved and acceptable overall results. The PAR index and ICON were valid measures to investigate the outcome of orthognathic treatment. IOFTN proved to be a useful tool in determining and prioritizing orthognathic treatment based purely on functional need.

Towards motion insensitive EEG-fMRI: Correcting motion-induced voltages and gradient artefact instability in EEG using an fMRI prospective motion correction (PMC) system.

The simultaneous acquisition of electroencephalography and functional magnetic resonance imaging (EEG-fMRI) is a multimodal technique extensively applied for mapping the human brain. However, the quality of EEG data obtained within the MRI environment is strongly affected by subject motion due to the induction of voltages in addition to artefacts caused by the scanning gradients and the heartbeat. This has limited its application in populations such as paediatric patients or to study epileptic seizure onset. Recent work has used a Moiré-phase grating and a MR-compatible camera to prospectively update image acquisition and improve fMRI quality (prospective motion correction: PMC). In this study, we use this technology to retrospectively reduce the spurious voltages induced by motion in the EEG data acquired inside the MRI scanner, with and without fMRI acquisitions. This was achieved by modelling induced voltages from the tracking system motion parameters; position and angles, their first derivative (velocities) and the velocity squared. This model was used to remove the voltages related to the detected motion via a linear regression. Since EEG quality during fMRI relies on a temporally stable gradient artefact (GA) template (calculated from averaging EEG epochs matched to scan volume or slice acquisition), this was evaluated in sessions both with and without motion contamination, and with and without PMC. We demonstrate that our approach is capable of significantly reducing motion-related artefact with a magnitude of up to 10mm of translation, 6° of rotation and velocities of 50mm/s, while preserving physiological information. We also demonstrate that the EEG-GA variance is not increased by the gradient direction changes associated with PMC. Provided a scan slice-based GA template is used (rather than a scan volume GA template) we demonstrate that EEG variance during motion can be supressed towards levels found when subjects are still. In summary, we show that PMC can be used to dramatically improve EEG quality during large amplitude movements, while benefiting from previously reported improvements in fMRI quality, and does not affect EEG data quality in the absence of large amplitude movements.

Cross-Cultural Validation and Psychometric Properties of the Arabic Brief Religious Coping Scale (A-BRCS).

The aim of this study was to translate and validate the psychometric properties of an Arabic Brief Religious Coping Scale. A descriptive correlational design was used to conduct the study among participants of 403 Iraqi secondary school students. The A-BRCS and both the subscales, positive and negative, had Cronbach's alphas of .70, .86 and .82, respectively. All inter-item and item-to-total correlations for each subscale were above the recommended criteria of .30. Factor loadings of the positive subscale using oblique (oblimin) and orthogonal (varimax) rotations ranged from .72 to .86 and from .71 to .86, respectively. Factor loadings of the negative subscale using oblimin and varimax rotations ranged from .64 to .83 and from .63 to .83, respectively. The A-BRCS was found to be a valid and reliable instrument to measure religious coping among Iraqi secondary school students.

Development of a novel smart scaffold for human skeletal muscle regeneration.

Skeletal muscle defects are notoriously difficult to manage and the current methods used are associated with many limitations. Engineered skeletal muscle tissue has the potential to provide a solution that circumvents these disadvantages. Our previous work has identified a novel three-dimensionally aligned degradable phosphate glass fibre scaffold that can support myoblast differentiation and maturation. This current study has further developed the scaffold by encasing the fibres within a collagen gel to produce a smart composite scaffold that provides key biomimetic cues and supports the formation of a tissue that may be implanted in vivo. The constructs formed were approximately 30 mm long and microscopic examination confirmed favourable unidirectional cell alignment. There was good cell survival, and gene expression studies demonstrated upregulation of the myogenic regulatory factors and developmental and adult myosin heavy chain isoforms indicating myofibre formation and maturation respectively. Compared with the three-dimensional glass fibre scaffolds, the composite scaffolds had later gene upregulation, however, the use of collagen gels reinforced with degradable aligned glass fibres offers the opportunity to create a tissue analogue that can be easily manipulated. Furthermore, the glass fibre ends could support tendon/bone formation, and the channels formed as the fibres degrade could allow for vascular ingrowth.

The influence of surface roughness and surface dynamics on the attachment of Methicillin-Resistant Staphylococcus aureus onto orthodontic retainer materials.

Staphylococci species have been isolated from removable orthodontic retainers. The aims of this study were to determine the most suitable device to analyze surface roughness of autopolymerized acrylic and thermoplastic materials and whether the surface dynamics of these materials influences the attachment of Methicillin-Resistant Staphylococcus aureus (MRSA). Clinically simulated samples of autopolymerized acrylic and thermoplastic material were first evaluated using laser non-contact, stylus mechanical profilometries and atomic force microscopy (AFM) followed by contact angle measurement to characterize their surface dynamics. Finally, an in vitro biofilm assay was carried out using a constant depth film fermentor to assess biofilm attachment. The results showed a significant difference between the roughness values obtained from the tested profilometers with the AFM exhibiting the most consistent roughness values. MRSA tended to accumulate initially within the microscopic irregularities of autopolymerized acrylic samples whereas acid-base and electron donor interactions influenced the bacterial attachment onto the thermoplastic samples.

The influences of nursing transformational leadership style on the quality of nurses' working lives in Taiwan: a cross-sectional quantitative study.

BACKGROUND: Taiwan's NHI system is one of the most successful health care models for countries around the globe. However, little research has demonstrated the mental health issues associated with nursing transformational leadership style under the NHI system, especially in the quality of nurses' working lives in Taiwan. It is important to know the relationship between transformational leadership style and the mental health of nurses, organisational commitment and job satisfaction. The research aimed to understand the influences of nursing transformational leadership style on the quality of nurses' working lives in Taiwan. The research hypothesis was that transformational leadership styles would have positive influence on the quality of nurses' working lives. METHODS: This was a cross-sectional quantitative study. Nurses from each type of hospital ownership (private, public and religious) were recruited. Participation was voluntary and signed informed consent was obtained. The inclusion criteria were nurses with at least one year's work experience in the hospitals. Self-administrated questionnaires were used. A total of 807 participants were contacted and 651 questionnaires were fully completed (response rate 80.7 %). A theory driven model was used to test the research hypotheses using structural equation modelling performed with AMOS 16.0. RESULTS: Transformational leadership contributes significantly to supervisor support. Workplace support, particularly from the supervisor, is an important mediator variable that explains the relationship between transformational leadership and job satisfaction. Organisational commitment was the strongest factor relevant to the general health well-being in Taiwanese nurses than job satisfaction. The hypothesized positive relationships between transformational leadership and all variables were supported by the data. CONCLUSIONS: Our findings have important consequences for organisational health. Our model demonstrates a complete picture of the work relationships on the quality of nurses' working lives. The results provided information about the subordinates' perceptions of transformational nursing leadership styles and mental health outcomes in different hospital settings, as well as identified organisational factors that could improve the quality of nurses' working lives.

Experiences and coping behaviours of adolescents in Pakistan with alopecia areata: an interpretative phenomenological analysis.

The study explored experiences of adolescents aged 15-19 with alopecia areata (AA) and investigated their accounts of coping behaviours. Interpretative Phenomenological Analysis was used to provide an in-depth and holistic perspective of their accounts. Semi-structured interviews were undertaken with a volunteer sample of eight respondents diagnosed with AA. Four key themes were identified: loss (self/social), concerns (physical/future), negative (emotions/thoughts), and coping styles (adaptive/maladaptive). Females experienced greater feelings of loss, were more concerned about their looks and their future, and reported more negative thoughts and emotions. Females felt angry and blamed God for their fate; males blamed both their fate and luck. Action-oriented and practical coping styles were adopted by all of them. After the realization that initial coping behaviours were ineffective, self-distraction, acceptance, and humour were used. Psychological relief followed with the practice of religion and planning for treatments to be undertaken in the future. The findings here are similar to research conducted in the West, though with more emphasis on religion. Health care providers and student counsellors need to understand the negative psychosocial consequences for adolescents living with a visible disfigurement and provide appropriate psychological and social support.

The effectiveness of Narrative Exposure Therapy with traumatised firefighters in Saudi Arabia: a randomized controlled study.

Firefighters are exposed to many traumatic events. The psychological costs of this exposure increase the risk of Post-Traumatic Stress disorder (PTSD), depression and anxiety. This study examined the effectiveness of Narrative Exposure Therapy (NET) as a short-term treatment for reducing PTSD symptoms among Saudi firefighters. A randomized waiting-list control study was conducted with 34 traumatized firefighters were randomly allocated to NET or Waiting-list Control (WLC). The NET group received four therapy sessions of 60-90 min over a three-week period; those in the WLC condition received the same sessions after a three-week waiting period. Participants in both groups were assessed at baseline, immediately post-intervention and at 3 and 6 month follow ups. NET led to significant reductions in PTSD symptoms, anxiety and depression compared with WLC. After the WLC group received treatment, it showed the same improvements as the NET group. This occurred immediately post-treatment in both groups, but was not sustained at 3 and 6 month follow ups. Coping strategies and social support led to significant changes only in follow up times. NET was effective in reducing PTSD symptoms in traumatised Saudi firefighters. This finding could be helpful in the management of PTSD among people who work as first responders such as firefighters, police officers and emergency medical personal, as well as security officers.
