Priorities for public health research on craniosynostosis: summary and recommendations from a Centers for Disease Control and Prevention-sponsored meeting

On June 8-9, 2006, the National Center on Birth Defects and Developmental Disabilities at the Centers for Disease Control and Prevention held a meeting entitled "Prioritizing a Public Health Research Agenda for Craniosynostosis". The meeting goals were to review current knowledge in the area, discuss research gaps, and identify future priorities for public health research. Participants with a broad range of expertise (including clinical and molecular genetics, cranial morphology, epidemiology, pediatrics, psychology, public health, and surgery) contributed to the development of the research agenda. Meeting participants were asked to consider public health significance and feasibility when identifying areas of priority for future public health research. Participants identified several priorities, including the need to better delineate the prevalence and phenotype of craniosynostosis (CS); to identify factors important in the causation of CS (including potentially modifiable environmental risk factors as well as genes involved in isolated CS and gene-gene and gene-environment interactions); and to better understand short- and long-term outcomes of CS (e.g., surgical, neurocognitive and neuropsychological outcomes, psychological adjustment, and social relationships) and issues related to clinical care that could affect those outcomes. The need for improved collaboration among clinical treatment centers and standardization of data collection to address these priorities was emphasized. These priorities will be used to guide future public health research on CS.     

A systematic scoping review of psychosocial and psychological factors associated with patient activation

ObjectivePatient activation has been identified as an important predictor of how patients manage their own health, but little is known about its determinants. In this scoping review, we aim to address this research gap by (1) identifying literature on psychosocial/psychological factors associated with patient activation, and (2) extracting and synthesizing major results reported on that relationship.MethodsUsing a systematic search of four electronic databases (Web of Science, PubMed, PsychInfo, CINAHL), our search algorithm combined related terms for “psychosocial factors” or “psychological factors” and “patient activation”.ResultsOf the 1128 records identified, we included 13 studies in this scoping review. In these, we identified 21 psychosocial/psychological factors that were significantly associated with patient activation. The four most frequently investigated factors were depression, self-efficacy, hope, and health status. Overall, the methodological quality of studies was low. The majority were cross sectional in design, and only one assessed causality.ConclusionsOur results suggest that psychosocial/psychological factors explain variations in patient activation. However, further research is needed to identify causal relationships between psychosocial/psychological factors and patient activation.Practice ImplicationsThe insights from our review could be used for designing and evaluating interventions to improve patient activation.     

Psychological adjustment and perceived social support in children with congenital/acquired limb deficiencies

The negative impact on psychological adjustment from the chronic strain of living with limb deficiencies appears to be mediated by perceived social support. A multifactorial investigation was conducted to identify empirically psychological adjustment correlates of perceived social support in 49 children with congenital/acquired limb deficiencies. A multiplicity of adjustment factors (depression, trait anxiety, self-esteem) was variously related to perceived parent, teacher, classmate, and friend social support. Hierarchical multiple regression analyses provide initial evidence of the potentially powerful effects of the social environment of the school setting, with perceived classmate social support the only significant predictor variable across depressive symptomatology, trait anxiety, and general self-esteem. The results are discussed as the first step in identifying the potential correlates of multiple perceived social support domains, which may provide empirical guidance for future intervention studies designed to modify adjustment factors in chronically ill and handicapped children.This research was supported by grants from the Shriners Hospitals for Crippled Children Research Fund and the Milo B. Brooks Foundation for Limb Deficient Children.     

A review of the predisposing,precipitating and perpetuating factors in Chronic Fatigue Syndrome in children and adolescents

Chronic Fatigue Syndrome (CFS) is a condition characterised by severe mental and physical fatigue coupled with profound disability. The purpose of this review was to investigate psychological, social and physiological factors associated with fatigue and disability in CFS in children and adolescents. The review aimed to gain an overview of the strength of evidence for the relationship between these different factors and CFS in young people. Seventy-nine studies met the inclusion criteria and were included in the review. A narrative synthesis of these studies was conducted. The strongest and most consistent finding was that rates of psychiatric co-morbidity, predominantly anxiety and depressive disorders, were higher in young people with CFS compared to healthy controls or illness control groups. Studies suggested that many children and adolescents with CFS reported that their illness began with an infection and there was some objective and prospective evidence to support this. Preliminary evidence suggested a link between CFS and a family history of CFS, high expectations from both the parent and child, personality traits such as conscientiousness and physical illness attributions. The evidence was limited by methodological problems. Few studies were prospective in nature and future research should address this. Clinical implications of the findings are discussed and a hypothesised model of the factors associated with CFS in children and adolescents is presented.     

A systematic review of the effects of postnatal maternal anxiety on children

Several decades of research have focused on the impact of exposure to postnatal depression on children, while anxiety has been largely overlooked. Estimates of the prevalence of postnatal maternal anxiety (PMA) range from 3% to 43%, suggesting PMA may be an important risk factor for adverse outcomes in children. This review summarizes what is known about the effects of PMA exposure on children and makes recommendations for future research. A systematic search of Ovid MEDLINE® and PsychINFO® through 2008 identified 18 studies that evaluated child outcomes associated with PMA exposure. Identified studies covered three domains: somatic, developmental, and psychological outcomes. The strongest evidence for an adverse effect of PMA exposure is in somatic and psychological outcomes; the evidence for an effect of PMA on child development is inconclusive. Methodological differences among the studies make comparisons difficult and there are a number of common limitations that challenge the validity of these studies.     

Computer-based psychological treatments for depression: a systematic review and meta-analysis

The aim of the paper was to systematically review the literature on computer-based psychological treatments for depression and conduct a meta-analysis of the RCT studies, including examining variables which may effect outcomes. Database and hand searches were made using specific search terms and inclusion criteria. The review included a total of 40 studies (45 published papers), and 19 RCTs (23 published papers) were included in a standard meta-analysis. The review describes the different computer-based treatments for depression, their design, communication types employed: synchronous, asynchronous, and face-to-face (F:F); alongside various types and frequency of support delivered. The evidence supports their effectiveness and highlights participant satisfaction. However, pertinent limitations are noted. Across 19 studies the meta-analysis revealed a moderate post-treatment pooled effect size d=.56 (95% confidence interval [CI] -.71, -.41), Z=7.48, p<.001). Supported interventions yielded better outcomes, along with greater retention. The results reported statistically significant clinical improvement and recovery post-treatment. The review and meta-analysis support the efficacy and effectiveness of computer-based psychological treatments for depression, in diverse settings and with different populations. Further research is needed, in particular to investigate the influence of therapist factors in supported treatments, the reasons for dropout, and the maintenance of gains post-treatment.     

The use of functional neuroimaging to evaluate psychological and other non-pharmacological treatments for clinical pain

A large number of studies have provided evidence for the efficacy of psychological and other non-pharmacological interventions in the treatment of chronic pain. While these methods are increasingly used to treat pain, remarkably few studies focused on the exploration of their neural correlates. The aim of this article was to review the findings from neuroimaging studies that evaluated the neural response to distraction-based techniques, cognitive behavioral therapy (CBT), clinical hypnosis, mental imagery, physical therapy/exercise, biofeedback, and mirror therapy. To date, the results from studies that used neuroimaging to evaluate these methods have not been conclusive and the experimental methods have been suboptimal for assessing clinical pain. Still, several different psychological and non-pharmacological treatment modalities were associated with increased pain-related activations of executive cognitive brain regions, such as the ventral- and dorsolateral prefrontal cortex. There was also evidence for decreased pain-related activations in afferent pain regions and limbic structures. If future studies will address the technical and methodological challenges of today's experiments, neuroimaging might have the potential of segregating the neural mechanisms of different treatment interventions and elucidate predictive and mediating factors for successful treatment outcomes. Evaluations of treatment-related brain changes (functional and structural) might also allow for sub-grouping of patients and help to develop individualized treatments.     

The relation between psychological factors and DNA-damage: a critical review

Investigating relations between psychological factors and DNA-damage can contribute to understanding how psychological factors affect the etiology and prognosis of relevant diseases (e.g., cancer, heart disease) at the fundamental level of mutated cells. This article critically reviews 21 studies in animals and humans testing relations between psychological factors and DNA-damage. After providing a biological background, we critically review each study. The findings in humans are mapped onto a model of stress, coping and health. These studies demonstrate causal relations between acute stressors and DNA-damage in animals and significant correlations between psychological factors (e.g., depression, coping) and DNA-damage in humans, which are moderated by gender. Possible mechanisms for these relations, limitations of studies, clinical implications and suggestions for future research are provided.     

Non-completion of personality disorder treatments: A systematic review of correlates,consequences, and interventions

Non-completion of treatment is a major concern in the provision of therapies for people diagnosed with personality disorder, with adverse consequences for services, therapists, and other patients. Of even greater concern is that non-completion of treatment may limit the effectiveness of therapy for individuals. Our main aim in this study was to conduct a systematic review of the literature on psychosocial treatments for personality disorder to identify factors associated with treatment non-completion. Two subsidiary aims were to identify studies that reported the relative outcomes of treatment completion and non-completion, and to identify studies that evaluated psychosocial interventions specifically aimed at improving retention in treatment. This information is potentially useful in informing selection criteria and directing efforts towards improving treatment engagement. Twenty-five empirical studies of factors predicting treatment non-completion were identified. The median non-completion rate was 37%. A range of patient characteristics, need factors, and environment factors were identified as associated with non-completion. However, the studies could not be considered homogeneous group for meta-analysis. Four studies investigated the effects of treatment non-completion, showing an association with adverse outcomes. Only two studies of interventions specifically aimed at reducing non-completion were identified. Implications for clinical practice and research are discussed.     

Therapeutic alliance in psychological therapy for people with schizophrenia and related psychoses: A systematic review

Therapeutic alliance is a key predictor of therapy outcomes. Alliance may be particularly pertinent for people with schizophrenia as this group often have a history of interpersonal trauma and relationship difficulties including difficult relationships with mental health staff. This review aimed to determine (a) the quality of therapeutic alliance between people with schizophrenia and their therapists; (b) whether alliance predicts therapeutic outcomes; and (c) variables associated with alliance. Databases were searched from inception up to April 2015. The search yielded 4,586 articles, resulting in 26 eligible studies, involving 18 independent samples. Weighted average client and therapist Working Alliance Inventory‐Short Form total scores were 64.51 and 61.26, respectively. There was evidence that alliance predicts overall psychotic symptomatic outcomes and preliminary evidence for alliance predicting rehospitalization, medication use, and self‐esteem outcomes. There was evidence for specific client‐related factors being linked to different perspectives of alliance. For example, poorer insight and previous sexual abuse were associated with worse client‐rated alliance, whereas baseline negative symptoms were associated with worse therapist‐rated alliance. Therapist and therapy‐related factors, including therapists' genuineness, trustworthiness, and empathy were associated with better client‐rated alliance, whereas suitability for therapy, homework compliance, and attendance were associated with better therapist‐rated alliance. Key clinical implications include the need to consider alliance from both client and therapist perspectives during therapy and training and supervision to enhance therapist qualities that foster good alliance. Future research requires longitudinal studies with larger samples that include pan‐theoretical, well‐validated alliance measures to determine causal predictor variables.     

Psychotherapy of bipolar disorder: a review

Background: Bipolar disorder is often only partially treated by medication alone, which has led to recent developments in the adjunctive psychological treatment of bipolar disorder. This paper aims to examine the current evidence for effectiveness of psychological interventions for bipolar disorder and to identify issues for future research in this area. Method: A review of outcome studies of psychological interventions reported since 1990, including psychoeducation, cognitive-behavioural, interpersonal and social rhythm and psychoanalytic therapy. Results: The research to date indicates that a range of psychological approaches appear to benefit people with bipolar disorder. The clearest evidence is for individual CBT which impacts on symptoms, social functioning and risk of relapse. Limitations: Many studies lack appropriate control groups and standardised measures of symptoms and diagnosis. Better designed studies would reduce the risk of over-estimates of effect sizes and subsequent failure to replicate. Further developments of psychotherapy need to be based on clear theoretical models of bipolar disorder. Conclusions: Many current studies are uncontrolled and of poor quality leading to a risk of over-estimating effectiveness of some interventions. Suggestions are made for future research including improving quality of studies, basing treatment developments on clear theoretical models and identifying specific treatment components for particular phases of the bipolar illness course.     

Total knee replacement: Is it really an effective procedure for all?

Total knee replacement (TKR) is considered an effective intervention for the treatment of chronic knee pain and disability. Yet there is increasing evidence, based on research using patient-based outcome measures, that a significant proportion of patients experience chronic knee pain, functional disability, a poor quality of life and dissatisfaction after TKR. Although some poor outcomes after TKR are due to surgical technique and implant factors, much of the pain and disability after surgery is medically unexplained. A range of possible patient factors could contribute to a poor outcome after TKR. Socio-demographic factors that have been found to correlate with a poor outcome after TKR include female gender, older age and low socio-economical status. Medical factors that are highly predictive of pain and disability after TKR are a greater number of co-morbidities and a worse pre-operative status. A range of psychological factors could be predictive of a poor outcome after surgery including depression, low self-efficacy, poor pain coping strategies, somatization, low social support and patient expectations. It is also proposed that a biological explanation for continuing pain after TKR could involve central sensitisation, a dysfunction of pain modulation by the central nervous system. To improve patient selection for TKR, future research needs to focus on developing a pre-operative screening protocol to identify those patients at risk of medically unexplained pain and disability after TKR.     

A review of empirically supported psychosocial interventions for pain and adherence outcomes in sickle cell disease

OBJECTIVE: To review empirical studies of psychological interventions for pain and adherence outcomes among patients with sickle cell disease. METHOD: We conducted a literature review of studies using psychological interventions targeted at pain and/or adherence behaviors related to sickle cell disease. The American Psychological Association Division 12 Task Force criteria (Chambless criteria) were used to evaluate the empirical support for three categories of interventions (cognitive-behavioral techniques, interventions aimed at behavioral change, and social support interventions). RESULTS: A small number of intervention studies met criteria for demonstrating empirical efficacy. As a group, cognitive-behavioral techniques fall into the category of probably efficacious for sickle cell pain. Other intervention types were limited by inadequate research methodologies. CONCLUSIONS: Future studies will need to more stringently test outcomes related to acute crises (e.g., pain episodes) as well as day-to-day management of sickle cell disease to clarify the most efficacious intervention approaches. Implications and suggestions for future research directions are discussed.     

Pretrauma risk factors for posttraumatic stress disorder: A systematic review of the literature

As it has become clear that most individuals exposed to trauma do not develop PTSD, it has become increasingly important to examine pretrauma risk factors. However, PTSD research has overwhelmingly relied on retrospective accounts of trauma, which is beleaguered by problems of recall bias. To further our understanding of PTSD's etiology, a systematic review of 54 prospective, longitudinal studies of PTSD published between 1991 and 2013 were examined. Inclusion criteria required that all individuals were assessed both before and after an index trauma. Results revealed six categories of pretrauma predictor variables: 1) cognitive abilities; 2) coping and response styles; 3) personality factors; 4) psychopathology; 5) psychophysiological factors; and 6) social ecological factors. The results indicated that many variables, previously considered outcomes of trauma, are pretrauma risk factors. The review considered these findings in the context of the extant retrospective PTSD literature in order to identify points of overlap and discrepancy. Pretrauma predictor categories were also used to conceptualize variable risk for PTSD. Limitations and directions for future research are discussed.     

Blunted cardiovascular and cortisol reactivity to acute psychological stress: A summary of results from the Dutch Famine Birth Cohort Study

The Dutch Famine Birth Cohort Study is a large population based study of late middle aged, overall healthy men and women whose health has been followed from 50 to 65 years of age. In a sample of 725 cohort members, an extensive psychological stress protocol was performed during which cardiovascular and cortisol responses were measured. In line with many previous studies, results showed that increased blood pressure responsiveness to the stress protocol was associated with an increased risk for hypertension 5 years later. However, decreased cardiovascular and/or cortisol stress reactivity were associated with obesity and the risk of becoming obese, symptoms of depression and anxiety, a poor self-reported health, poor lung function, and poor cognitive function (all p for statistical tests < 0.05). These associations generally survived adjustment for a range of potential confounders, including resting cardiovascular and cortisol activity, commitment to the stress tasks, sex, age, smoking and use of medication. Results from these studies agree with recent evidence that low biological reactivity to acute psychological stress may not always be beneficial for health but instead seems to be a marker for a range of negative health outcomes. Future studies have to point out whether low stress reactivity precedes or follows these negative health outcomes.     

Religious coping and psychological adjustment to stress: a meta-analysis

A growing body of literature suggests that people often turn to religion when coping with stressful events. However, studies on the efficacy of religious coping for people dealing with stressful situations have yielded mixed results. No published studies to date have attempted to quantitatively synthesize the research on religious coping and psychological adjustment to stress. The purpose of the current study was to synthesize the research on situation-specific religious coping methods and quantitatively determine their efficacy for people dealing with stressful situations. A meta-analysis of 49 relevant studies with a total of 105 effect sizes was conducted in order to quantitatively examine the relationship between religious coping and psychological adjustment to stress. Four types of relationships were investigated: positive religious coping with positive psychological adjustment, positive religious coping with negative psychological adjustment, negative religious coping with positive psychological adjustment, and negative religious coping with negative psychological adjustment. The results of the study generally supported the hypotheses that positive and negative forms of religious coping are related to positive and negative psychological adjustment to stress, respectively. Implications of the findings and their limitations are discussed.     

Stress,psychological distress,psychosocial factors,menopause symptoms and physical health in women

Objectives

Relatively few studies have evaluated relationships between stress, psychological distress, psychosocial factors and menopause symptoms, and none have evaluated emotional intelligence (EI) in relation to menopause. In this study, direct and indirect relationships were evaluated between stress, psychological distress, psychosocial factors (e.g. social support, coping, EI), menopause symptom severity and physical health in middle-aged women.

Methods

One hundred and sixteen women aged 45–55 years were recruited through women's health centres and community organizations. They completed a short questionnaire asking about stress, psychological distress (i.e. anxiety, depression), EI, attitude to menopause, menopause symptoms and physical health.

Results

Low emotional intelligence was found to be related to worse menopause symptoms and physical health, and these associations were partly mediated by high stress, anxiety and depression, a negative attitude to menopause and low proactive coping.

Conclusions

Women with high EI appear to hold more positive attitudes to menopause and experience less severe stress, psychological distress and menopause symptoms and better physical health. These results suggest that women who expect menopause to be a negative experience or are highly stressed or distressed may be more likely to experience a more negative menopause.     

Reactions to Health-Related Social Control in Young Adults with Type 1 Diabetes

Health-related social control refers to individuals’ attempts to influence another’s health behavior. We describe social control experienced by 109 adults aged 18–35 with Type 1 diabetes, and examine the influence of different types of social control on behavioral and psychological outcomes. Using a self-administered questionnaire, telephone interview, and chart review, we assessed individuals’ social control experiences, behavioral and psychological reactions, psychological adjustment, metabolic control, socio-demographics, and clinical factors at baseline, and psychological adjustment and metabolic control at 6-months follow-up. Most participants (85%) reported experiencing social control. Regression analyses revealed that more frequent negative control predicted less behavior change and more negative cognitive reactions concurrently, and decreases in psychological adjustment over time. More frequent reinforcement/modeling and structural changes predicted more positive emotional reactions, but were not associated with behavior change, psychological adjustment, or metabolic control. Use of direct persuasion was associated with more pretending of behavior change. These results suggest that negative social control attempts by social network members may be counter-productive.     

A scoping review of the psychological responses to interval exercise: is interval exercise a viable alternative to traditional exercise?

While considerable evidence suggests that interval exercise confers numerous physiological adaptations linked to improved health, its psychological consequences and behavioural implications are less clear and the subject of intense debate. The purpose of this scoping review was to catalogue studies investigating the psychological responses to interval exercise in order to identify what psychological outcomes have been assessed, the research methods used, and the results. A secondary objective was to identify research issues and gaps. Forty-two published articles met the review inclusion/exclusion criteria. These studies involved 1258 participants drawn from various active/inactive and healthy/unhealthy populations, and 55 interval exercise protocols (69% high-intensity interval training [HIIT], 27% sprint interval training [SIT], and 4% body-weight interval training [BWIT]). Affect and enjoyment were the most frequently studied psychological outcomes. Post-exercise assessments indicate that overall, enjoyment of, and preferences for interval exercise are equal or greater than for continuous exercise, and participants can hold relatively positive social cognitions regarding interval exercise. Although several methodological issues (e.g., inconsistent use of terminology, measures and protocols) and gaps (e.g., data on adherence and real-world protocols) require attention, from a psychological perspective, the emerging data support the viability of interval exercise as an alternative to continuous exercise.     

The impact of biopsychosocial factors on quality of life: women with primary biliary cirrhosis on waiting list and post liver transplantation

Objectives. Primary biliary cirrhosis (PBC) is the second most common reason for liver transplants among women in the USA. While survival rates are high, there is evidence of persistent problems post‐transplant. This study aimed to identify significant contributors to quality of life (QOL) for women with PBC on waiting list (WL) and post‐transplant (PT) and compare QOL in each group with US population norms. Design. A cross‐sectional, two‐group study design was used. Methods. WL and PT participants were recruited through medical centres and on‐line. QOL was measured by the Short Form‐36 and an indicator of Social QOL created for this study. A biopsychosocial model incorporating demographic, biomedical, psychological, and sociological factors guided choice of variables affecting QOL. Analyses examined (1) all factors for differences between WL and PT groups, (2) association between factors and QOL outcomes within each group, (3) multivariate regression of QOL on factors in the model for the sample as a whole, and (4) comparison of QOL outcomes with national norms. Results. One hundred women with PBC participated in the study, 25 on WL and 75 PT. Group comparisons showed improvement for PT participants in most biomedical and psychological variables and in QOL outcomes. QOL was related to many, but not all, of the variables in the model. In multivariate analysis, Fatigue, Depression, Coping, and Education – but not Transplant Status – were identified as indicators of QOL. Physical QOL improved significantly after 5 years PT, when it was no longer worse than national norms. Mental QOL remained worse than national norms despite distance in time from transplant. Conclusions. The model proved useful in identifying a range of factors that contributed to QOL for women with PBC before and after transplant. Recommendations were made for clinical practice to improve QOL through a combination of treatment and self‐management.
