Neurocognitive functioning among children and young people with Duchenne Muscular Dystrophy: A systematic review and meta-analysis.

Objective: The neurocognitive aspects of DMD have received less attention than the physiological sequalae. This study conducted a systematic review and meta-analysis of available literature on the neurocognitive profile of children and young people with DMD. Method: Five databases (EMBASE, Medline, PsycInfo, Scopus and Web of Science) and the grey literature was searched on 27th January 2023. Eligible articles were available in English and reported neurocognitive outcomes. Neurocognitive domains reported in a comparable way across a minimum of three studies were included. The neurocognitive domains of Full-Scale IQ (FSIQ), Verbal IQ (VIQ), Performance IQ (PIQ) and Working memory (WMI) derived from Wechsler scales and receptive vocabulary ability derived from the Peabody Picture Verbal Test (PPVT) were included. A single mean meta-analysis was completed. Results: Relevant data was extracted and presented for 38 eligible studies; 2 of which are from grey literature. Results suggest children with DMD perform around 1SD below non-clinical norms for FSIQ, PIQ, VIQ and WMI. Unlike VIQ, scores derived from the PPVT were within the non-clinical norms. Studies were of moderate - high quality, there was significant heterogeneity and no publication bias. Conclusion: A systematic review of working memory has not previously been completed, it appears that children with DMD perform around 1SD below the mean, like FSIQ, PIQVIQ and WMI. The PPVT is a measure of receptive verbal ability and caution is recommended around the interchangeability of PPVT scores and the wider construct of verbal intelligence.

Contributing factors to secondary traumatic stress and vicarious posttraumatic growth in therapists.

Alongside the recognized potential negative repercussions of working as a psychological therapist, there is growing interest in the potential positive impacts of engaging in such work. The current study used a cross-sectional online survey design to explore the impact of a range of demographic, work-related, and compassion-related factors on levels of secondary traumatic stress (STS) and vicarious posttraumatic growth (VPTG) in an international sample of 359 psychological therapists. Hierarchical multiple regressions demonstrated that burnout, lower levels of self-compassion, having a personal trauma history, reporting a higher percentage of working time with a trauma focus, and being female were the statistically significant contributors to STS scores, explaining 40.8% of the variance, F(9, 304) = 23.2, p <.001. For VPTG, higher compassion satisfaction, higher self-compassion, higher STS, a higher percentage of working time with a trauma focus, fewer years qualified, being male, and having a personal trauma history were all statistically significant contributors, explaining 27.3% of the variance, F (10, 304) = 11.37, p <.001. The findings illustrate the potential risk and protective factors for developing STS and clarify factors that may increase the likelihood of experiencing VPTG. Implications for psychological therapists and the organizations and institutions for which they work are considered along with potential directions for future research in the discussion.

A comparison between auditory hallucinations, interpretation of voices, and formal thought disorder in dissociative identity disorder and schizophrenia spectrum disorders.

OBJECTIVES: Dissociative identity disorder (DID) and schizophrenia-spectrum disorders (SSD) share some overlapping phenomenological features making accurate diagnosis more difficult. Childhood abuse and depersonalization have been associated with psychotic symptoms across psychological disorders but their relationship to psychotic phenomenology remains understudied. METHOD: The present study used quantitative measures to examine (1) similarities and differences in phenomenological voice hearing experiences, interpretations of voices, and thought disorder symptoms in individuals with DID (n = 44) or SSD (n = 45), and (2) whether depersonalization and childhood maltreatment influenced the initial pattern of findings. RESULTS: DID participants perceived their voices as being more internally located and generated, louder, and uncontrollable than SSD participants. Furthermore, the DID participants endorsed a greater frequency of thought disorder symptoms. Adding the covariates (sex, depersonalization, and child maltreatment) did not change the findings associated with location and origin of voices, and derailment, but there were now no differences in loudness or controllability. However, the schizophrenia sample reported more distress and metaphysical beliefs associated with voices, as well as more thought disorder incoherence and word substitution with the covariates controlled. CONCLUSION: While tentative, metaphysical interpretations of voices, incoherent thoughts and word substitution may reflect more psychotic processes.

Empirically Derived Patterns of Posttraumatic Stress and Growth: A Systematic Review.

The relationship between posttraumatic stress (PTS) and posttraumatic growth (PTG) has been extensively studied; however, the nature of the relationship remains unclear. Inconsistencies in the literature could be, in part, due to the use of variable level approaches. Person centered methods may further our understanding of this relationship, as they enable the identification of clinically meaningful subgroups based on PTS/PTG scores. This review aimed to identify commonly found subgroups of PTS and PTG, clinically relevant factors that distinguish the subgroups and to critically appraise the utility of categorizing individuals into subgroups based on PTS/PTG scores. Five databases (Embase, Medline, Web of Science, PILOTS, and PsycINFO) were searched. Seven studies (with a total of eight study samples; n = 6,776) met the eligibility criteria. A narrative synthesis of the findings revealed that the majority of the analyses (n = 6) found three patterns of PTS/PTG. These were categorized as: (1) low PTS/PTG (representing 26.89% of the entire sample), (2) high PTS/PTG (weighted mean percentage = 20.05%), and (3) low PTS/high PTG (weighted mean percentage = 43.1%). The role of social support was examined in five studies and higher social support was consistently found to predict membership in the low PTS/high PTG class. All five studies that examined the role of trauma characteristics found that it was a significant predictor of class membership. These findings could inform the developments of tailored interventions. The utility of person-centered approaches was discussed and recommendations to improve the application and reporting of such methods were made.

Dissociation as a Mediator Between Childhood Abuse and Hallucinations: An Exploratory Investigation Using Dissociative Identity Disorder and Schizophrenia Spectrum Disorders.

Previous research has shown that the relationship between childhood abuse and the presence of auditory hallucinations is mediated by dissociation, specifically depersonalization and absorption. The current study assessed dissociation as a mediator of the relationship between childhood abuse and auditory hallucination frequency, characteristics and associated distress in those with dissociative identity disorder (DID; n = 50) and schizophrenia spectrum disorders (SSD; n = 49). It also tested whether dissociation mediated the relationship between childhood abuse and the presence of non-auditory hallucinations. Participants completed measures of childhood abuse, dissociation, auditory hallucination frequency, characteristics, distress, and non-auditory hallucinations. With distress associated with auditory hallucinations as the outcome, depersonalization was a mediator in the DID group. For non-auditory hallucinations, in the DID group depersonalization and amnesia were mediators between childhood abuse and the presence of visual, tactile and olfactory hallucinations. In the SSD group absorption mediated between childhood abuse and visual, olfactory and gustatory hallucinations. Results suggest that the presence of non-auditory hallucinations in DID and SSD are associated with different dissociative experiences.

The Structure of the Prodromal Questionnaire-16 (PQ-16): Exploratory and confirmatory factor analyses in a general non-help-seeking population sample.

AIMS: To examine the structure of the Prodromal Questionnaire (PQ-16) in a non-help-seeking population through exploratory factor analysis and confirmatory factor analysis. Previous studies have not looked at the structure of this self-report measure outside clinical settings. METHODS: Participants (n = 1045) were recruited through Amazon's Mechanical Turk (MTurk), and then completed the PQ-16. The data set was split randomly in two, one being used for exploratory factor analysis (EFA) and the other for confirmatory factor analysis (CFA). A polychoric correlation matrix was created and EFA was used to explore the factor structure of the PQ-16. Four models were tested through CFA to determine best fit: one, two, three and four-factor models were all analysed. RESULTS: EFA indicated a two-factor structure in the PQ-16 in a non-help-seeking population (with a mean age = 29.7 years). Factor 1 represented perceptual abnormalities/hallucinations and factor 2 general symptoms associated with psychosis-risk. CFA indicated that all the proposed models were suitable fits for the dataset. Fit indices for the three-factor model (factor 1 representing perceptual abnormalities/hallucinations, factor 2 unusual thought content, and factor 3 negative symptom) indicated that it appeared to be a better fit for the data than the one, two, and four factor models. CONCLUSIONS: This study suggests that a three-factor model of the PQ-16 is a better fit than other proposed models in a non-help-seeking population. Future research of the structure of the PQ-16 in this population may benefit from recruiting subjects with a lower mean age than the current study.

Exploring the relationship between alienation appraisals, trauma, posttraumatic stress, and depression.

OBJECTIVE: Cognitive models posit negative trauma appraisals as maintaining symptoms of posttraumatic stress disorder. Recent research has demonstrated that alienation appraisals (feeling disconnected from the self and others) are salient in trauma-related distress. Studies show that alienation appraisals fully mediated the relationship between trauma exposure and symptoms of posttraumatic stress disorder (PTSD) in trauma-exposed adults. This study explored alienation appraisals in student and clinical samples, assessing whether alienation significantly mediated the relationship between cumulative trauma and trauma-related distress. It also explored whether alexithymia, social support, and loneliness also mediated the relationship between cumulative trauma and markers of trauma-related distress, clarifying the role of alienation. METHOD: Mediation and hierarchical regression models were tested with questionnaire data from a student sample (N = 100) and clinical sample of trauma-exposed treatment-seeking adults (N = 93). RESULTS: In the student sample, alienation (B = 1.27) fully mediated the relationship between cumulative trauma and posttraumatic stress, but not depression. When alexithymia, social support, and loneliness were entered as parallel mediators, only alienation appraisals (B = 1.03) significantly mediated the relationship between cumulative trauma and posttraumatic stress. For the clinical sample, alienation appraisals (ß = .53) were the only significant predictor of posttraumatic stress, while alienation appraisals (ß = .75) and, to a lesser extent, social support (ß = .19) and loneliness (ß = .30) significantly predicted depression. CONCLUSIONS: Alienation was a salient predictor of posttraumatic distress. Clinical assessment of alienation appraisals is recommended to inform psychological interventions for trauma survivors.

A Meta-Analysis of the Efficacy of Virtual Reality and In Vivo Exposure Therapy as Psychological Interventions for Public Speaking Anxiety.

Public speaking anxiety (PSA) is a prevalent condition with disabling occupational, educational, and social consequences. Exposure therapy is a commonly utilized approach for treating PSA. Traditionally, this intervention has been delivered as in vivo exposure therapy (IVET). Limitations inherent to in vivo as a mode of delivery have been identified and studies have increasingly explored the use of Virtual Reality Exposure Therapy (VRET) as an alternative. Understanding the efficacy of both VRET and IVET as psychological interventions for PSA is important. A systematic search identified 11 studies with 508 participants. Meta-analysis yielded a large significant effect wherein VRET resulted in significant reductions in PSA versus control of -1.39 (Z = 3.96, p < .001) and a similar large significant effect wherein IVET resulted in significant reductions in PSA versus control of -1.41 (Z = 7.51, p < .001). Although IVET was marginally superior to VRET, both interventions proved efficacious. Given the advantages of utilizing VRET over IVET future research and clinical practice could explore VRET as a treatment option for PSA.

Motor difficulties in young people who offend.

BACKGROUND: Research suggests that motor difficulties may be closely associated with severe emotional and behavioural problems in children. However, there is limited research on the role of motor function in young adults who offend. AIMS: To assess motor skills, balance, and primary reflex persistence in young people who offend, and to examine the relative association of different motor factors with self-reported levels of aggression. METHODS: We recruited three groups of males (14-18 years); young people serving custodial sentences (n = 33) in a youth justice centre, and an IQ-matched comparison group (n = 36) and an average-IQ comparison group (n = 38) of non-offenders. All completed a standardised test of motor skills, clinical assessment protocols for balance and primary reflex persistence, and a standardised self-report behavioural rating scale. RESULTS: The youth justice group showed significantly lower abilities in some motor skills and balance and significantly higher levels of primary reflex persistence and aggression than both comparison groups. In a multiple regression model, only manual dexterity (p = .032) and primary reflex persistence (p = .002) were significant predictors of aggression. CONCLUSIONS: A broad range of motor difficulties are likely to occur in young people who offend. We discuss the implications of motor difficulties for approaches to rehabilitation of persistent offenders.

360° Video virtual reality exposure therapy for public speaking anxiety: A randomized controlled trial.

Public speaking anxiety (PSA) is a prevalent condition which is highly interrelated with social anxiety. PSA can be effectively treated with exposure therapy. Virtual reality exposure therapy (VRET) is increasingly being explored as a novel and cost-effective mode of treatment. No previous randomized controlled trial has examined whether stand-alone 360° video VRET is an effective intervention for treating PSA and interrelated disorder relevant fears. Further, studies have not explored whether 360° video content influences VRET outcomes. Participants with high PSA (n = 51) were randomly allocated to: 360° video VRET incorporating stimuli of audiences (360°Audience) (n = 17), 360° video VRET incorporating stimuli of empty rooms (360°Empty) (n = 16) and no treatment control (n = 18). Outcomes were measured over five time-points. Mixed ANOVA revealed a significant interaction between time and intervention group for PSA, social anxiety and fear of negative evaluation (FNE). Within-group analysis demonstrated there was a significant pre-intervention to post-intervention reduction across measures for both 360° video VRET groups: PSA 360°Audience (ηp2 = .90, p<.001), 360°Empty (ηp2 = .71, p < .001); social anxiety 360°Audience (ηp2 = .49, p=.002), 360°Empty (ηp2 = .39, p = .009); FNE 360°Audience (ηp2 = .59, p<.001), 360°Empty (ηp2 = .43, p = .006). Active intervention participants showed significant improvement from pre-intervention to 10-week follow-up on all measures. Findings illustrate that 360° video VRET is an efficacious way to significantly reduce PSA, social anxiety and FNE.

A meta-analytic review of the relationship between attachment styles and posttraumatic growth.

OBJECTIVE: The present review aimed to examine the relationship between attachment styles and posttraumatic growth in adults exposed to traumatizing events. METHOD: A systematic literature search resulted in the inclusion of 14 studies in the review. Four correlational meta-analyses of the relationship between the attachment styles of secure, dismissive, preoccupied, and fearful, and posttraumatic growth, were conducted. RESULTS: These revealed a significant small positive relationship between secure attachment and posttraumatic growth (r = 0.21, p < 0.001); a significant small negative relationship between dismissive attachment and posttraumatic growth (r = -0.12, p < 0.001), and a weak relationship between preoccupied attachment and posttraumatic growth (r = -0.04, p = 0.235), and fearful attachment and posttraumatic growth (r = 0.08, p = 0.248). CONCLUSIONS: The relationship between attachment styles and posttraumatic growth is modest and may be better explained by other variables. Nonetheless, findings provide useful information for clinicians regarding the potential small impact of attachment style following traumatizing exposure. Implications for future research are highlighted with respect to methodological rigor and the role of other potentially influential variables.

Dog Owners' Survey reveals Medical Alert Dogs can alert to multiple conditions and multiple people.

Medical Alert Dogs (MADs) are a promising support system for a variety of medical conditions. Emerging anecdotal reports suggest that dogs may alert to additional health conditions and different people other than those that they were trained for or initially began alerting. As the use of medical alert dogs increases, it is imperative that such claims are documented empirically. The overall aims of this study were to record the proportion of MAD owners who have a dog that alerts to multiple health conditions or to people other than the target person and to determine whether any sociodemographic variables were associated with dogs alerting to multiple conditions, multiple people, or both. MAD owners completed an online survey that contained a series of forced choice questions. Sixty-one participants reported a total of 33 different conditions to which dogs alerted. Eighty-four percent of participants reported that their dog alerted to multiple conditions and 54% reported that their dog alerted to multiple people. This is the first study to document that a large percentage of people report that their MAD alerts to multiple conditions and/or to multiple people. We present a discussion of how these alerting abilities could develop, but questions about the underlying mechanisms remain.

Alcohol attention bias in 14-16 year old adolescents: an eye tracking study.

RATIONALE: Theoretical models regarding the automaticity of attentional processes highlight a progression of attentional bias style from controlled to automatic in drinking populations as alcohol use progresses. Previous research has focused on older adolescent and adult drinking populations at later stages in their drinking career. OBJECTIVES: The aim of this study was to investigate alcohol attention bias in 14-16-year-old adolescent social drinkers and abstainers. METHODS: Alcohol attention bias was measured in social drinking and abstaining groups in an eye-tracking paradigm. Questionnaires measured alcohol use, expectancies, exposure and socially desirable response styles. RESULTS: Social drinkers fixated to alcohol stimuli more frequently and spent a larger proportion of their fixation time attending to alcohol stimuli compared to non-drinkers. Groups displayed differences in their style of attentional processing of alcohol-related information, with heavy drinkers fixating significantly longer to alcohol information across alcohol stimulus presentation and exhibiting a delayed disengagement style of alcohol attention bias that differentiated them from light drinking and abstaining peers. All social drinkers fixated significantly more than abstainers in the latter half of alcohol stimulus presentation. CONCLUSION: Alcohol attention bias was present in this adolescent sample. Drinking subgroups are defined from abstaining peers by unique features of their attentional bias that are controlled in nature. These findings are comparable to those in other adolescent and adult social drinking populations. The identification of specific attentional bias features according to drinking subpopulations has implications for our theoretical understanding of developing alcohol attention bias and problematic drinking behaviours, as well as at-risk identification and early intervention.

Reaching consensus on the principles of trauma-informed care in early intervention psychosis services: A Delphi study.

AIM: The current study sought to conceptualize and reach consensus on the principles of trauma-informed care in early intervention psychosis services. METHODS: A three-phase Delphi method was employed in this study. Experts included researchers, service providers and Experts by Experience in the area of early intervention in psychosis. In the initial qualitative phase, an expert panel (n = 57) shared their views on the constituents of trauma-informed care in early intervention psychosis services. Thematic analysis led to the generation of statement items. The expert panel was asked to rate the extent to which each statement item was an essential principle of trauma-informed care, leading to consensus of endorsed principles. RESULTS: Qualitative analysis of the first phase data led to the identification of 185 distinct statements which were compiled into an online questionnaire for the panel to rate in Phase 2. The Phase 2 questionnaire was completed by 42 experts, with the endorsement of seven principles. In Phase 3, the panel were invited to re-rate 24 statements. This phase was completed by 39 panel members, with the acceptance of a further nine principles. Consensus was achieved resulting in the endorsement of 16 essential principles of trauma-informed care. CONCLUSIONS: The study offers novel understanding of the conceptualisation of trauma-informed care in early intervention services and suggests principles which are widely agreed by experts in the field. The recommendations may inform the adoption of consistently delivered trauma-informed care in early interventions in psychosis and facilitate the evaluation and development of services.

Childhood Physical and Sexual Abuse as a Predictor of Reoffending: A Systematic Review.

Experiences of childhood trauma such as physical and sexual abuse are common among offender populations, and a trauma history is related to increases in the risk of criminal conduct. Previous reviews on the link between childhood trauma and reoffending are limited in scope as they only investigate adolescent populations. The aim of the current systematic review was to explore the association between childhood physical and sexual abuse and its prediction on actual reoffending rates in adult population(s). Four databases (PsycINFO, Web of Science, PubMed, and PILOTS) were searched, and the final included articles were quality assessed by two reviewers. A total of 3,151 studies were identified, and 13 met the a priori eligibility criteria. Most of the studies obtained high quality ratings. A narrative synthesis of the results suggests that childhood physical and sexual abuse are generally high among the prison population and tend to be even higher among those who reoffend. A substantial number of studies found that childhood physical and sexual abuse predict reoffending, and the majority of the studies found a positive direction for this association, albeit of a small magnitude. These findings suggest that prisons should consider trauma-informed assessment and rehabilitation of offenders.

The association between sleep quality and attenuated psychotic symptoms.

AIM: To determine if poor sleep makes a unique contribution in predicting the likelihood of experiencing six or more attenuated psychotic symptoms and associated distress, after examining and controlling for sociodemographic factors, depression and drug/alcohol use. METHOD: An online survey was conducted using Amazon's online crowdsourcing service Mechanical Turk (MTurk). The sample was 1013 adults (18 to 36 years) from the general population in the United States. The survey consisted of the Prodromal Questionnaire 16 (PQ-16), the Pittsburgh Sleep Quality Index, the Patient Health Questionnaire 9, the Drug Abuse Screening Test 10 and the Alcohol Use Disorders Identification Test. Regression analyses were performed with the PQ-16 as the dependent variable, and sleep quality as the predictor variable, holding constant sociodemographic variables, depression, and alcohol/drug abuse. RESULTS: 37% of the sample endorsed six or more PQ-16 items, which may be suggestive of an at-risk mental state, with sleep disturbance significantly increasing the likelihood (Odds ratio 2.09 < .001) of endorsing six or more PQ-16 items. After controlling for sociodemographic variables, depression and drug/alcohol abuse, poor sleep quality made a unique contribution of 5.8% of the variance accounted for in level of distress experienced by attenuated psychotic symptoms. CONCLUSION: Effective treatment of sleep disturbance may reduce the likelihood ofexperiencing attenuated psychotic symptoms and associated distress.

Investigating predictors of trauma induced data-driven processing and its impact on attention bias and free recall.

BACKGROUND: Whilst data-driven processing (DDP) during trauma has been shown to play a role in poor memory integration and is associated with post-traumatic stress disorder (PTSD) re-experiencing symptoms, the pre-trauma risk factors and related cognitive mechanisms are uncertain. AIMS: This experimental study aimed to investigate predictors of peri-traumatic DDP, as well as its role in attention bias to threat and free recall. METHOD: A virtual reality video was used to simulate an analogue trauma. Questionnaires, a free recall task, and an eye-tracking measure assessed cognitive changes after exposure. RESULTS: Regression analysis demonstrated that trait dissociation at pre-exposure to trauma significantly predicted DDP. Attention bias towards threat-related images was found. Results showed that DDP and poorer free recall predicted attention bias to threat images and higher levels of DDP actually predicted higher overall scores in the free recall task. CONCLUSIONS: This study showed that DDP is strongly linked to dissociative traits, and along with memory disintegration it may predict attention changes after exposure to a trauma.

A Meta-Analytic Review of the Association Between Alienation Appraisals and Posttraumatic Stress Disorder Symptoms in Trauma-Exposed Adults.

Ehlers and Clark's (2000) cognitive model of posttraumatic stress disorder (PTSD) highlights the importance of negative appraisals in maintaining posttraumatic stress. Recent research suggests that alienation appraisals, defined as feeling disconnected from the self and others, mediate the association between traumatic experiences and subsequent PTSD symptoms. To our knowledge, no systematic review has yet explored the relation between alienation appraisals and PTSD symptoms in trauma-exposed adults, despite the important clinical implications posed by this association. A systematic search of the SCOPUS, Web of Science, PsycInfo, MEDLINE, CINAHL Plus, and PILOTS databases resulted in 470 studies, nine of which met full inclusion criteria. Studies were quality-assessed for risk of bias using the Quality Assessment Tool for Studies with Diverse Designs (QATSDD) quality assessment tool. A random-effects meta-analysis for the association between alienation appraisals and PTSD symptoms showed a large total effect size, r = .57, 95% CI [.46, .66], z = 8.41, p < .001. This large effect suggests that as alienation appraisals increase, PTSD symptoms increase. Although a strong positive association was found between alienation and PTSD symptoms, the mechanism of this association remains unclear. Limitations of the research included significant heterogeneity across studies and the fact that data were correlational. Future research to explore why alienation appraisals are significant in posttraumatic stress may further help to inform therapeutic approaches to targeting alienation appraisals in trauma survivors. Recommendations are made for the clinical assessment of alienation appraisals when exploring the impact of the traumatic experience on the survivor.

Alienation Appraisals Mediate the Relationships between Childhood Trauma and Multiple Markers of Posttraumatic Stress.

Rates of posttraumatic stress are elevated in individuals who have experienced childhood and/or cumulative trauma, and trauma appraisals have been suggested as a possible mediator of this effect. This study tested the proposed mediating role of trauma appraisals between both childhood and cumulative trauma, and two markers of trauma-related distress; posttraumatic stress and depression. Mediation models were developed and tested with data collected from a sample of trauma-exposed, treatment receiving adults (N = 106). Trauma appraisals fully mediated relationships between childhood trauma and PTSD/depression. Appraisals also mediated the relationships between cumulative trauma and depression. When appraisal subscales were simultaneously entered, alienation appraisals were the only significant mediator of these relationships. The study found support for the proposed mediating role of trauma appraisals between different forms of trauma and trauma related distress. Alienation appraisals were particularly emphasised.

Motor problems in children with severe emotional and behavioural difficulties.

BACKGROUND: There is growing evidence that children with motor difficulties are at risk of psychosocial problems and vice versa. However, it is not clear how far different aspects of motor function are predictive of psychosocial well-being in the context of other powerful factors, such as family upset, that are known to affect psychosocial development. AIMS: To investigate the role of basic motor skills and primary reflex persistence in young children with severe emotional and behavioural difficulties (EBD). SAMPLE: From a total sample of 225 children, three groups were selected: children excluded from school (severe EBD) (n = 29), a male comparison group (n = 38), and a female comparison group (n = 45). The groups were matched (at group level) on age, IQ, and level of social disadvantage. METHOD: All of the selected children completed a range of standardized motor, cognitive, social, and behavioural measures, as well as a clinical protocol for primary reflex persistence. RESULTS: Children with severe EBD had significant levels of motor difficulties, primary reflex persistence, and family upset, as well as significant literacy problems, attention deficits, and raised levels of hyperactivity/impulsivity relative to the comparison groups. A hierarchical multiple regression analysis revealed that basic motor skills, primary reflex persistence, family upset, hyperactivity, and literacy were all significant predictors of psychosocial functioning. CONCLUSIONS: The findings suggest that motor difficulties and primary reflex persistence may act as independent stressors of psychosocial functioning in children with EBD. We suggest that specific movement interventions should be adopted to complement existing provision for children at risk of psychosocial problems.
