RESUMEN

Schizophrenia is a prototypical network disorder with widespread brain-morphological alterations, yet it remains unclear whether these distributed alterations robustly reflect the underlying network layout. We tested whether large-scale structural alterations in schizophrenia relate to normative structural and functional connectome architecture, and systematically evaluated robustness and generalizability of these network-level alterations. Leveraging anatomical MRI scans from 2439 adults with schizophrenia and 2867 healthy controls from 26 ENIGMA sites and normative data from the Human Connectome Project (n = 207), we evaluated structural alterations of schizophrenia against two network susceptibility models: (i) hub vulnerability, which examines associations between regional network centrality and magnitude of disease-related alterations; (ii) epicenter mapping, which identifies regions whose typical connectivity profile most closely resembles the disease-related morphological alterations. To assess generalizability and specificity, we contextualized the influence of site, disease stages, and individual clinical factors and compared network associations of schizophrenia with that found in affective disorders. Our findings show schizophrenia-related cortical thinning is spatially associated with functional and structural hubs, suggesting that highly interconnected regions are more vulnerable to morphological alterations. Predominantly temporo-paralimbic and frontal regions emerged as epicenters with connectivity profiles linked to schizophrenia's alteration patterns. Findings were robust across sites, disease stages, and related to individual symptoms. Moreover, transdiagnostic comparisons revealed overlapping epicenters in schizophrenia and bipolar, but not major depressive disorder, suggestive of a pathophysiological continuity within the schizophrenia-bipolar-spectrum. In sum, cortical alterations over the course of schizophrenia robustly follow brain network architecture, emphasizing marked hub susceptibility and temporo-frontal epicenters at both the level of the group and the individual. Subtle variations of epicenters across disease stages suggest interacting pathological processes, while associations with patient-specific symptoms support additional inter-individual variability of hub vulnerability and epicenters in schizophrenia. Our work outlines potential pathways to better understand macroscale structural alterations, and inter- individual variability in schizophrenia.

RESUMEN

Left-right asymmetry is an important organizing feature of the healthy brain that may be altered in schizophrenia, but most studies have used relatively small samples and heterogeneous approaches, resulting in equivocal findings. We carried out the largest case-control study of structural brain asymmetries in schizophrenia, with MRI data from 5,080 affected individuals and 6,015 controls across 46 datasets, using a single image analysis protocol. Asymmetry indexes were calculated for global and regional cortical thickness, surface area, and subcortical volume measures. Differences of asymmetry were calculated between affected individuals and controls per dataset, and effect sizes were meta-analyzed across datasets. Small average case-control differences were observed for thickness asymmetries of the rostral anterior cingulate and the middle temporal gyrus, both driven by thinner left-hemispheric cortices in schizophrenia. Analyses of these asymmetries with respect to the use of antipsychotic medication and other clinical variables did not show any significant associations. Assessment of age- and sex-specific effects revealed a stronger average leftward asymmetry of pallidum volume between older cases and controls. Case-control differences in a multivariate context were assessed in a subset of the data (N = 2,029), which revealed that 7% of the variance across all structural asymmetries was explained by case-control status. Subtle case-control differences of brain macrostructural asymmetry may reflect differences at the molecular, cytoarchitectonic, or circuit levels that have functional relevance for the disorder. Reduced left middle temporal cortical thickness is consistent with altered left-hemisphere language network organization in schizophrenia.

RESUMEN

OBJECTIVE: Communication skills training (CST) programs within postgraduate psychiatry training are rare. ComPsych CST utilises simulated patients (SPs) for trainees to practice communication skills for discussing severe mental illness with patients and their families/carers. This study examined the applicability of using SPs in a psychiatry-specific CST. METHODS: A total of 41 postgraduate psychiatry trainees attended at least one of four modules of training in their cohort year and completed a questionnaire after each module presenting eight questions rating the use of SPs and ratings of course deliverables. RESULTS: Overall, trainees rated contact with SPs very highly across all modules, with a mean rating of 9.11 out of 10 (SD = 0.97). Trainees agreed that SPs appeared authentic, that their reactions showed they listened to the trainee. CONCLUSIONS: Trainees valued training with SPs, providing evidence that using SPs for psychiatry-specific CST is feasible. Despite subjectivity, this is valuable to course providers as it highlights benefits perceived by trainees to be useful and provides further evidence for the program's feasibility and utility.

RESUMEN

OBJECTIVE: ComPsych communication skills training is designed to teach psychiatry trainees effective skills and strategies for undertaking key communication tasks relating to mental illness, such as schizophrenia, with patients and their families/carers. This study examined the program's feasibility, utility, and trainees' self-efficacy. METHODS: Trainee cohorts attending their first year formal education course were recruited annually over 4 years between 2015 and 2018. Each trainee attended at least one session of training in their cohort year. Trainees completed a questionnaire presenting questions about personal demographics, their perceived confidence in communication, and the effectiveness of elements of training delivery. A total of 41 trainee psychiatrists (15 male) completed the questionnaires presented at four time points (two pre-training and two post-training). RESULTS: Participants reported a significant increase in confidence in their own communication skills post-training (d = 1.12) and rated elements of training delivery (video feedback, feedback from peers in small groups, small group facilitation, and use of simulated patients) as significantly more helpful or effective post-training (d = 0.42). Trainees also reported a significantly increased ability to critically evaluate their own communication skills post-training (d = 0.59), suggesting an increased ability to recognize their own communication skill competence. CONCLUSIONS: Following ComPsych training, trainees were more confident discussing information about schizophrenia with patients and their families/carers and were more able to critically evaluate their own communication skills: an important feature of good clinical acumen. These subjective ratings provide important self-efficacy information, including the benefits perceived and evidence of the program's feasibility and utility.

RESUMEN

OBJECTIVE: To establish any health outcomes for infants to age one, associated with their mother having a diagnosis of an active eating disorder during pregnancy or the 12-month postnatal period. METHOD: A qualitative systematic literature review of numerous databases (Medline, PsycINFO, CINAHL, Scopus, Cochrane Library, MedNar, PsycExtra, National Institute for Health and Care Excellence and Open Grey) was performed examining any infant health outcomes. RESULTS: This resulted in 22 included studies (17 cohort, 3 cross-sectional, 1 case controlled and 1 mixed methods study). A range of adverse infant outcomes including poor birth, growth and interactional feeding outcomes were identified. DISCUSSION: Antenatal identification and treatment for women with an eating disorder during the perinatal period and their infants are vital. Optimizing pregnancy nutrition, maternal eating disorder symptoms and feeding interactions appear particularly important.

RESUMEN

Autism is a neurodevelopmental condition with associated difficulties that present differently across individuals. One such difficulty is recognizing basic and complex facial expressions. Research has previously found that there are many evidence-based support programs available for building non-verbal communication skills. These programs are frequently administered with a therapist or in a group setting, making them inflexible in nature. Programs hosted on e-technology are becoming increasingly popular, with many parents supportive of them. Applications (apps) that are hosted on technology such as iPads or mobile phones allow users to engage in building skills in real-time social settings and own what they are learning. These technologies are frequently used by autistic children, with apps typically focusing on identifying facial features. Yet at this current time, there are mixed reviews of how to design such programs and what their theoretical backing is, with many studies using a mix of observation and psychological assessments as outcome measures. Eye-tracking and electroencephalography are established methodologies that measure neural processing and gaze behaviors while viewing faces. To better support the field moving forward, objective measures such as these are a way to measure outcomes of apps that are designed for helping children on the spectrum build skills in understanding facial expressions.

RESUMEN

A common limitation of neuroimaging studies is their small sample sizes. To overcome this hurdle, the Enhancing Neuro Imaging Genetics through Meta-Analysis (ENIGMA) Consortium combines neuroimaging data from many institutions worldwide. However, this introduces heterogeneity due to different scanning devices and sequences. ENIGMA projects commonly address this heterogeneity with random-effects meta-analysis or mixed-effects mega-analysis. Here we tested whether the batch adjustment method, ComBat, can further reduce site-related heterogeneity and thus increase statistical power. We conducted random-effects meta-analyses, mixed-effects mega-analyses and ComBat mega-analyses to compare cortical thickness, surface area and subcortical volumes between 2897 individuals with a diagnosis of schizophrenia and 3141 healthy controls from 33 sites. Specifically, we compared the imaging data between individuals with schizophrenia and healthy controls, covarying for age and sex. The use of ComBat substantially increased the statistical significance of the findings as compared to random-effects meta-analyses. The findings were more similar when comparing ComBat with mixed-effects mega-analysis, although ComBat still slightly increased the statistical significance. ComBat also showed increased statistical power when we repeated the analyses with fewer sites. Results were nearly identical when we applied the ComBat harmonization separately for cortical thickness, cortical surface area and subcortical volumes. Therefore, we recommend applying the ComBat function to attenuate potential effects of site in ENIGMA projects and other multi-site structural imaging work. We provide easy-to-use functions in R that work even if imaging data are partially missing in some brain regions, and they can be trained with one data set and then applied to another (a requirement for some analyses such as machine learning).

RESUMEN

OBJECTIVES: Large-scale genetic analysis of common variation in schizophrenia has been a powerful approach to understanding this complex but highly heritable psychotic disorder. To further investigate loci, genes and pathways associated more specifically in the well-characterized Australian Schizophrenia Research Bank cohort, we applied genome-wide single-nucleotide polymorphism analysis in these three annotation categories. METHODS: We performed a case-control genome-wide association study in 429 schizophrenia samples and 255 controls. Post-genome-wide association study analyses were then integrated with genomic annotations to explore the enrichment of variation at the gene and pathway level. We also examine candidate single-nucleotide polymorphisms with potential function within expression quantitative trait loci and investigate overall enrichment of variation within tissue-specific functional regulatory domains of the genome. RESULTS: The strongest finding (p = 2.01 × 10-6, odds ratio = 1.82, 95% confidence interval = [1.42, 2.33]) in genome-wide association study was with rs10252923 at 7q21.13, downstream of FZD1 (frizzled class receptor 1). While this did not stand alone after correction, the involvement of FZD1 was supported by gene-based analysis, which exceeded the threshold for genome-wide significance (p = 2.78 × 10-6). CONCLUSION: The identification of FZD1, as an independent association signal at the gene level, supports the hypothesis that the Wnt signalling pathway is altered in the pathogenesis of schizophrenia and may be an important target for therapeutic development.

RESUMEN

BACKGROUND: The profile of cortical neuroanatomical abnormalities in schizophrenia is not fully understood, despite hundreds of published structural brain imaging studies. This study presents the first meta-analysis of cortical thickness and surface area abnormalities in schizophrenia conducted by the ENIGMA (Enhancing Neuro Imaging Genetics through Meta Analysis) Schizophrenia Working Group. METHODS: The study included data from 4474 individuals with schizophrenia (mean age, 32.3 years; range, 11-78 years; 66% male) and 5098 healthy volunteers (mean age, 32.8 years; range, 10-87 years; 53% male) assessed with standardized methods at 39 centers worldwide. RESULTS: Compared with healthy volunteers, individuals with schizophrenia have widespread thinner cortex (left/right hemisphere: Cohen's d = -0.530/-0.516) and smaller surface area (left/right hemisphere: Cohen's d = -0.251/-0.254), with the largest effect sizes for both in frontal and temporal lobe regions. Regional group differences in cortical thickness remained significant when statistically controlling for global cortical thickness, suggesting regional specificity. In contrast, effects for cortical surface area appear global. Case-control, negative, cortical thickness effect sizes were two to three times larger in individuals receiving antipsychotic medication relative to unmedicated individuals. Negative correlations between age and bilateral temporal pole thickness were stronger in individuals with schizophrenia than in healthy volunteers. Regional cortical thickness showed significant negative correlations with normalized medication dose, symptom severity, and duration of illness and positive correlations with age at onset. CONCLUSIONS: The findings indicate that the ENIGMA meta-analysis approach can achieve robust findings in clinical neuroscience studies; also, medication effects should be taken into account in future genetic association studies of cortical thickness in schizophrenia.

RESUMEN

OBJECTIVES: A range of communication skills training programmes have been developed targeting trainees in various medical specialties, predominantly in oncology but to a lesser extent in psychiatry. Effective communication is fundamental to the assessment and treatment of psychiatric conditions, but there has been less attention to this in clinical practice for psychiatrists in training. This review examines the outcomes of communication skills training interventions in psychiatric specialty training. METHODS: The published English-language literature was examined using multiple online databases, grey literature and hand searches. The review was conducted and reported using Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. Studies examining the efficacy of communication skills training were included. Randomised controlled trials, pseudo-randomised studies and quasi-experimental studies, as well as observational analytical studies and qualitative studies that met criteria, were selected and critically appraised. No limits were applied for date of publication up until 16 July 2016. RESULTS: Total search results yielded 2574 records. Of these, 12 studies were identified and reviewed. Two were randomised controlled trials and the remaining 10 were one-group pretest/posttest designs or posttest-only designs, including self-report evaluations of communication skills training and objective evaluations of trainee skills. There were no studies with outcomes related to behaviour change or patient outcomes. Two randomised controlled trials reported an improvement in clinician empathy and psychotherapeutic interviewing skills due to specific training protocols focused on those areas. Non-randomised studies showed varying levels of skills gains and self-reported trainee satisfaction ratings with programmes, with the intervention being some form of communication skills training. CONCLUSION: The heterogeneity of communication skills training is a barrier to evaluating the efficacy of different communication skills training programmes. Further validation studies examining specific models and frameworks would support a stronger evidence base for communication skills training in psychiatry. It remains a challenge to develop research to investigate behaviour change over time in clinical practice or to measure patient outcomes due to the effects of communication skills training.

RESUMEN

White matter abnormalities associated with schizophrenia have been widely reported, although the consistency of findings across studies is moderate. In this study, neuroimaging was used to investigate white matter pathology and its impact on whole-brain white matter connectivity in one of the largest samples of patients with schizophrenia. Fractional anisotropy (FA) and mean diffusivity (MD) were compared between patients with schizophrenia or schizoaffective disorder (n = 326) and age-matched healthy controls (n = 197). Between-group differences in FA and MD were assessed using voxel-based analysis and permutation testing. Automated whole-brain white matter fiber tracking and the network-based statistic were used to characterize the impact of white matter pathology on the connectome and its rich club. Significant reductions in FA associated with schizophrenia were widespread, encompassing more than 40% (234ml) of cerebral white matter by volume and involving all cerebral lobes. Significant increases in MD were also widespread and distributed similarly. The corpus callosum, cingulum, and thalamic radiations exhibited the most extensive pathology according to effect size. More than 50% of cortico-cortical and cortico-subcortical white matter fiber bundles comprising the connectome were disrupted in schizophrenia. Connections between hub regions comprising the rich club were disproportionately affected. Pathology did not differ between patients with schizophrenia and schizoaffective disorder and was not mediated by medication. In conclusion, although connectivity between cerebral hubs is most extensively disturbed in schizophrenia, white matter pathology is widespread, affecting all cerebral lobes and the cerebellum, leading to disruptions in the majority of the brain's fiber bundles.

RESUMEN

OBJECTIVE: Mental health clinicians can experience difficulties communicating diagnostic information to patients and their families/carers, especially about distressing psychiatric disorders such as schizophrenia. There is evidence for the effectiveness of communication skills training (CST) for improving diagnostic discussions, particularly in specialties such as oncology, but only limited evidence exists about CST for psychiatry. This study evaluated a CST program specifically developed for psychiatry residents called ComPsych that focuses on conveying diagnostic and prognostic information about schizophrenia. METHOD: The ComPsych program consists of an introductory lecture, module booklets for trainees, and exemplary skills videos, followed by small group role-plays with simulated patients (SPs) led by a trained facilitator. A standardized patient assessment (SPA) was digitally recorded pre- and post-training with a SP using a standardized scenario in a time-limited (15 min) period. Recorded SPAs were independently rated using a validated coding system (ComSkil) to identify frequency of skills used in five skills categories (agenda setting, checking, questioning, information organization, and empathic communication). RESULTS: Thirty trainees (15 males and 15 females; median age = 32) undertaking their vocational specialty training in psychiatry participated in ComPsych training and pre- and post-ComPsych SPAs. Skills increased post-training for agenda setting (d = -0.82), while questioning skills (d = 0.56) decreased. There were no significant differences in any other skills grouping, although checking, information organization, and empathic communication skills tended to increase post-training. A dose effect was observed for agenda setting, with trainees who attended more CST sessions outperforming those attending fewer. CONCLUSION: Findings support the generalization and translation of ComPsych CST to psychiatry.

RESUMEN

IMPORTANCE: A recently published study of national data by McGrath et al in 2014 showed increased risk of schizophrenia (SCZ) in offspring associated with both early and delayed parental age, consistent with a U-shaped relationship. However, it remains unclear if the risk to the child is due to psychosocial factors associated with parental age or if those at higher risk for SCZ tend to have children at an earlier or later age. OBJECTIVE: To determine if there is a genetic association between SCZ and age at first birth (AFB) using genetically informative but independently ascertained data sets. DESIGN, SETTING, AND PARTICIPANTS: This investigation used multiple independent genome-wide association study data sets. The SCZ sample comprised 18 957 SCZ cases and 22 673 controls in a genome-wide association study from the second phase of the Psychiatric Genomics Consortium, and the AFB sample comprised 12 247 genotyped women measured for AFB from the following 4 community cohorts: Estonia (Estonian Genome Center Biobank, University of Tartu), the Netherlands (LifeLines Cohort Study), Sweden (Swedish Twin Registry), and the United Kingdom (TwinsUK). Schizophrenia genetic risk for each woman in the AFB community sample was estimated using genetic effects inferred from the SCZ genome-wide association study. MAIN OUTCOMES AND MEASURES: We tested if SCZ genetic risk was a significant predictor of response variables based on published polynomial functions that described the relationship between maternal age and SCZ risk in offspring in Denmark. We substituted AFB for maternal age in these functions, one of which was corrected for the age of the father, and found that the fit was superior for the model without adjustment for the father's age. RESULTS: We observed a U-shaped relationship between SCZ risk and AFB in the community cohorts, consistent with the previously reported relationship between SCZ risk in offspring and maternal age when not adjusted for the age of the father. We confirmed that SCZ risk profile scores significantly predicted the response variables (coefficient of determination R2 = 1.1E-03, P = 4.1E-04), reflecting the published relationship between maternal age and SCZ risk in offspring by McGrath et al in 2014. CONCLUSIONS AND RELEVANCE: This study provides evidence for a significant overlap between genetic factors associated with risk of SCZ and genetic factors associated with AFB. It has been reported that SCZ risk associated with increased maternal age is explained by the age of the father and that de novo mutations that occur more frequently in the germline of older men are the underlying causal mechanism. This explanation may need to be revised if, as suggested herein and if replicated in future studies, there is also increased genetic risk of SCZ in older mothers.

RESUMEN

OBJECTIVE: Mental health clinicians can experience problems communicating distressing diagnostic information to patients and their families, especially about severe mental illnesses such as schizophrenia. Evidence suggests that interpersonal communication skills can be effectively taught, as has been demonstrated in the specialty of oncology. However, very little literature exists with respect to interpersonal communication skills training for psychiatry. This paper provides an overview of the communication skills training literature. CONCLUSIONS: The report reveals significant gaps exist and highlights the need for advanced communication skills training for mental health clinicians, particularly about communicating a diagnosis and/or prognosis of schizophrenia. A new communication skills training framework for psychiatry is described, based on that used in oncology as a model. This model promotes applied skills and processes that are easily adapted for use in psychiatry, providing an effective platform for the development of similar training programs for psychiatric clinical practice.

RESUMEN

OBJECTIVE: This study investigated the ability of the Audio Recorded Cognitive Screen (ARCS) to detect cognitive deficit in individuals with schizophrenia, relative to the Mini Mental State Examination (MMSE) and the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS), and explored the associations between the ARCS and functional outcomes. We hypothesised that the ARCS would be able to better discriminate between individuals with schizophrenia and healthy controls than the MMSE, and that ARCS performance would be correlated with measures of social and vocational functioning. METHODS: The participants were 19 community-dwelling individuals with schizophrenia or schizoaffective disorder and 19 healthy controls recruited from the Australian Schizophrenia Research Bank (ASRB). Participants completed the ARCS, MMSE, and self-report measures of social and vocational functioning. Clinical and diagnostic data stored by the ASRB were also utilised. RESULTS: The schizophrenia group performed worse than the control group on the ARCS, with memory, t(36)=2.49, p=0.02, 95% CI [-1.84, -18.79] and fluency, t(36)=2.40, p=0.02, 95% CI [-1.87, -22.24] domains being the main discriminating measures. The RBANS also discriminated between the two groups, and ARCS and RBANS total scores were moderately to strongly correlated. There was no difference between the two groups on the MMSE after controlling for demographic variables. ARCS performance was associated with employment status [χ2(1)=7.16, p=0.007]. CONCLUSION: The ARCS may be sensitive to the cognitive deficits in outpatients with schizophrenia and an indicator of functional outcomes in this population.

RESUMEN

BACKGROUND: Transparent diagnostic communication is considered best practice for clinicians. However, while patients expect to receive a schizophrenia diagnosis from their psychiatrist, research suggests mental health clinicians are often reluctant to provide this information to patients. AIM: This study examines the perceptions of people with schizophrenia surrounding the communication of this diagnosis. METHODS: A generic qualitative methodological approach was used. A total of 14 patients with schizophrenia were recruited through community mental health services (n = 10) and the Australia Schizophrenia Research Bank (ASRB; n = 4) in New South Wales (NSW), Australia. Semi-structured interviews were used to explore the experiences and perceptions of people with schizophrenia about the way a schizophrenia diagnosis was communicated by mental health clinicians. Interviews were recorded, transcribed, codes generated and thematic analysis undertaken aided by NVivo. RESULTS: The majority of participants felt it was beneficial to receive a diagnosis despite acknowledging the distress this information sometimes caused, with many reporting this knowledge gave a sense of relief. It helped to understand their experiences and behaviours, improved their trust in the psychiatric system and increased treatment adherence. However, many reported difficulty in obtaining information about their condition, its treatment and prognosis, and expressed dissatisfaction with the way a diagnosis of schizophrenia was communicated. DISCUSSION: Insight into the perceptions and experiences of patients with schizophrenia about how a diagnosis of schizophrenia is communicated is a key outcome of this research. This knowledge will inform the development of future training programmes for mental health clinicians, and influence the clinical practice of health professionals treating patients with schizophrenia.

RESUMEN

OBJECTIVE: Important gaps are observed in clinicians' communication with patients and families about psychiatric disorders such as schizophrenia. Communication skills can be taught, and models for education in these skills have been developed in other fields of medicine, such as oncology, providing a framework for training communication skills relevant to psychiatric practice. This study evaluated a pilot communication skills education program for psychiatry trainees, focusing on discussing schizophrenia diagnosis and prognosis. METHOD: Communication skills training modules were developed based on an existing theoretical framework (ComSkil), adapted for discussing a schizophrenia diagnosis and prognosis. Pre-post training rating of self-reported confidence in a range of communication tasks was obtained, along with trainee views on the training methods. RESULTS: Thirty-eight participants completed the training. Significant improvements in confidence were reported post training for discussing schizophrenia prognosis, including an increased capacity to critically evaluate their own communication skills. Participants reported high levels of satisfaction with the program. CONCLUSION: This preliminary study provides support for the translation of a well-established educational model to psychiatric training addressing core clinical communication tasks and provides the foundation for the development of a more comprehensive evaluation and an extended curriculum regarding other aspects of care for patients with schizophrenia: ongoing management and recovery, dealing with conflict, and conducting a family interview.

RESUMEN

OBJECTIVE: This research sought to gain insight into the processes used by clinicians to discuss a schizophrenia diagnosis with patients/families, with the aim of informing the development of a communications skills training program. METHODS: A generic qualitative methodological approach was used. Sixteen mental health clinicians were recruited. Semi-structured individual interviews were used to explore their perceptions and experiences communicating a schizophrenia diagnosis. Interviews were recorded, transcribed, and thematic analysis undertaken. RESULTS: There were five key themes relating to the process of communication about a diagnosis of schizophrenia: (1) orientation to patient care, (2) planning of communication, (3) the impact of team leadership and inter/intra-professional functioning on communication tasks, (4) the roles of different clinicians in communicating about diagnosis and treatment, and (5) time and resource deficiencies. Despite expressing care and concern for vulnerable patients and embracing the concept of multidisciplinary teams, communicating diagnostic information to patients and families was generally unplanned for, with little consistency regarding leadership approaches, or how the team communicated diagnostic information to the patient and family. This contributed to tensions between different team members. CONCLUSION: The findings demonstrated a number of issues compromising good communication around a schizophrenia diagnosis, both in terms of clinician skill and clinical context, and support the importance of education and training for all members of the multidisciplinary team about their role in the communication process.
