Dispersed white roots in red beetroot influence the accuracy of root identification based on colours for intercropping studies.

PURPOSE: Beetroot is a model crop for studying root competition in intercropping systems because its red-coloured roots facilitate non-destructive visual discrimination with other root systems of intercropped plants. However, beetroot also has white roots, which could alter how root competition is interpreted. Here we investigated the quantity of white versus red roots in beetroot to quantify the effect of this phenomenon. METHODS: Beetroot was mono-cropped or inter-cropped with white cabbage in a field trial. The distribution of beetroot roots was recorded to 2.5 m soil depth on three dates following the minirhizotron method. Roots in each 0.5 m soil layer were counted and categorised into groups based on colour (white roots, coloured roots, and white roots traced back to be coloured) to investigate the influence of white roots on accuracy of root registration. A pot experiment was conducted with three cultivars to verify if white roots are a general characteristic of beetroot. RESULTS: White roots in mono-cropped beetroot represented 2.5-4.8% of total roots, on average, across the rooted soil profile. However, white roots represented 6.9% and 11.6% of total roots in the deepest soil layer during August and October, respectively. White roots caused mono-cropped beetroot roots to be underestimated by 1-22% based on root colour discrimination. However, tracing white roots backwards and forwards to coloured parts of roots reduced underestimates to 0.5-15%. Intercropping did not influence the traceability of white roots compared to monocropping. The highest occurrence of white roots appeared during the early growth period and in the deepest soil layers, indicating a linkage to younger roots or higher root proliferation rates. CONCLUSION: Beetroot represents a model crop for visual studies linking eco-physiology and root proliferation. The white roots of beetroot must be incorporated by studies of root competition in intercropping systems that use colour as a criterion.

Validity and reliability of the Danish version of QUALIDEM.

INTRODUCTION: QUALIDEM is a dementia-specific QoL instrument that allows a proxy-based Quality of Life rating in all stages of dementia. It was originally developed in The Netherlands and has later been translated into English and German. This study endeavoured to translate, cross-culturally adapt and test important psychometric properties of a Danish version in a cross-sectional validation study with a nested test-retest design. METHOD: All items underwent forward and backward translation by bilingual academics. Persons with dementia were recruited from 28 healthcare units in a Danish municipality. The severity of dementia was determined using a pragmatic approach allowing the site team to trichotomise the disease (mild, moderate-severe and very severe) before scoring the QUALIDEM. Psychometric properties for QUALIDEM were determined for item characteristics, construct validity, internal consistency, test-retest reliability, measurement error and floor and ceiling effects. The study was approved by The Danish Data Protection Agency. RESULTS: A total of 169 persons with dementia, aged 51-103, were included. The construct validity testing showed that the overall proportion of correctly hypothesised correlations was 83%. Testing for internal consistency, Cronbach's α ranged from 0.65 to 0.85 in mild-severe dementia with three out of nine subscales having values below 0.7. For very severe dementia, Cronbach's α ranged from 0.44 to 0.81, with three out of six subscales having insufficient values. For test-retest reliability, the intra-class correlation coefficients ranged from 0.56 to 0.86. The 'scale width' method revealed a marked ceiling effect in all subscales ranging from 30.6% to 87.7%. DISCUSSION: The QUALIDEM was successfully translated and cross-culturally adapted into Danish. Most subscales show acceptable internal consistency and test-retest reliability. However, a substantial measurement error and ceiling effect was present in most subscales. CONCLUSION: With few exceptions, the subscales of the Danish version of QUALIDEM have acceptable validity and reliability. Future research should address the limitations of the ceiling effects.

Factors influencing functioning after volar locking plate fixation of distal radius fractures: a scoping review of 148 studies.

BACKGROUND AND PURPOSE: A better understanding of factors that influence functioning may improve the identification of patients with distal radius fractures (DRFs) who need hand therapy. The purpose of this scoping review was to provide a comprehensive overview of factors that have been evaluated for their influence on hand functioning following volar plate fixation of DRFs. MATERIAL AND METHODS: 6 databases were searched from 2005 to 2021 for publications regarding surgical treatment for a DRF with a volar locking plate. Included studies evaluated demographic, perioperative, and postoperative factors within the 6 weeks post-surgery for their influence on functioning at least 3 months post-surgery. Functioning was assessed with patient-reported outcome measures. The factors were categorized into themes and mapped to the International Classification of Functioning, Disability and Health (ICF). RESULTS: 148 studies were included. 708 factors were categorized into 39 themes (e.g. pain) and mapped to the ICF components. The themes were primarily mapped to "body functions and structures" (n = 26) and rarely to "activities and participation" (n = 5). Fracture type (n = 40), age (n = 38), and sex (n = 22) were the most frequently evaluated factors. CONCLUSION: This scoping review identified an extensive number of factors evaluated within 6 weeks after surgery for their influence on functioning at least 3 months after volar plate fixation of a DRF and the existing research has primarily evaluated factors related to "body functions and structures," with limited focus on factors related to "activities and participation."

Development and field-testing of the Dementia Carer Assessment of Support Needs Tool (DeCANT).

OBJECTIVES: Caring for a person with dementia is associated with poor mental, physical, and social health, which makes it important to consider how carers are best supported in their caring role to preserve both their and the person with dementia's well-being. At present, a robust instrument to assess carers' support needs does not exist. This study aimed to develop a self-reported questionnaire to assess the support needs of carers of people with dementia. The objectives were to: (1) generate items, (2) pilot test, and (3) field-test the questionnaire. DESIGN: Development and field-testing of a new questionnaire. SETTINGS: Primary and secondary health and social care of informal carers and people with dementia in nine municipalities and one dementia clinic in a hospital in Denmark. PARTICIPANTS: Eight experts, 12 carers, and 7 digital users participated in pilot testing. 301 carers participated in field-testing. MEASUREMENTS: Items for inclusion were generated based on interviews and literature review. An iterative process of data collection was applied to establish face and content validity of the Dementia Carer Assessment of Support Needs Tool (DeCANT) using Content Validity Index among experts and cognitive interviews with carers. Field-testing of DeCANT among carers included using the 12-item Short Form Health Survey, the Barthel-20 Index, and the Neuropsychiatric Inventory. RESULTS: Initially, an item pool of 63 items was generated, and pilot testing reduced this to 42 items. Subsequent field-testing resulted in a 25-item version of DeCANT, and confirmatory factor analysis of three hypothesized models demonstrated a marginally better fit to a four-factor model with fit indices of: χ2 = 775.170 (p < 0.001), root mean square error of approximation = 0.073, Comparative Fit Index = 0.946, the Tucker-Lewis Index = 0.938, and weighted root mean residual (WRMR) = 1.265. CONCLUSIONS: DeCANT is a 25-item carer-reported questionnaire that can be used to help identify their support needs when caring for a person with dementia to enable supportive interventions and improve carers' health and well-being.

Stepwise mass spectrometry-based approach for confirming the presence of benzoxazinoids in herbs and vegetables.

INTRODUCTION: Benzoxazinoids (BXs) are plant phytochemicals that have both defensive properties in plants and therapeutic effects in humans. The presence of BXs has been largely studied in the Poaceae family (monocots). To study the presence or absence of BXs in dicotyledons and monocotyledons outside the Poaceae family, parts of 24 plant species at several growth stages were selected for analysis, some of which were already known to contain BXs. OBJECTIVES: To devise a stepwise mass spectrometry-based approach for confirming the presence of BXs in plant samples, and to use the method to explore the status of BXs in selected plant species. EXPERIMENTAL: Plant samples were extracted using accelerated solvent extraction and analysed using triple-quadrupole liquid chromatography-mass spectrometry. RESULTS: The use of different columns, double mass transitions, and ion ratios proved to be a robust tool for confirming the presence of BXs in different plant species. By this method, the presence of BXs was confirmed in three of the 24 species. Double-hexose forms of BXs, which have not been reported before in dicotyledons, were confirmed to be present in the dicotyledon plants Acanthus mollis and Lamium galeobdolon, and the presence of BXs in the seeds of Consolida orientalis is reported for the first time here. High concentrations of BXs were found in the aerial parts of Acanthus mollis and Lamium galeobdolon, at 20 and 32 µmol/g plant dry weight, respectively. CONCLUSIONS: The stepwise approach described in this work confirmed the presence of BXs in new samples.

Informal carers' support needs when caring for a person with dementia - A scoping literature review.

BACKGROUND: Informal carers of people with dementia report having unmet needs for support and few supportive interventions have been shown to be effective. There is a need to develop needs assessment instruments and supportive interventions with a holistic and person-centred approach to meet the various and complex needs of carers. The aim of this study was to provide an overview of carers' support needs when caring for people with dementia with the objectives to map and synthesise knowledge on key concepts of carers' support needs. METHODS: A scoping review methodology was used. A literature search was conducted in PsycINFO, CINAHL, PubMed and EMBASE between January 2007 and October 2019. Three authors independently selected articles meeting the inclusion criteria, and data were extracted using a matrix developed for that purpose. Inductive content analysis was used to synthesise key concepts of carers' support needs. RESULTS: The search identified 2748 articles after removing duplicates, and 122 articles were included in the mapping of carers' support needs. Synthesising carers' support needs indicated that the full extent of support needs emerges in the interaction between the carer and the person cared for and that it is possible to categorise support needs into four key concepts related to: 1) the carer as a person, 2) managing being a carer, 3) providing care, and 4) knowledge of dementia. CONCLUSION: The findings of this study help to map a framework describing carers' support needs that may guide the development of future needs assessment instruments and supportive interventions.

'I know his needs better than my own' - carers' support needs when caring for a person with dementia.

BACKGROUND: Caring for a person with dementia predisposes informal carers (carers) to mental and physical disability. Carers tend to focus on the needs of the person with dementia and have difficulties expressing their own needs for support. No instrument has yet been developed to directly assess carers' support needs. The aim of this study is to clarify the main categories of carers' support needs to inform future development of an instrument to assess carers' support needs. METHODS: A qualitative approach combining focus group interviews with carers and professionals and individual interviews were used. RESULTS: Carers' support needs were categorised into four areas: (i) daily life when caring for a person with dementia, (ii) focus on themselves, (iii) maintain own well-being, and (iv) communicate and interact with surroundings. DISCUSSION: Carers have support needs in common regardless of the relation to the person with dementia. Carers tend to focus on the needs of the person with dementia, thus not knowing their own needs. The four main categories clarified in this study may inform the foundation of developing an instrument to facilitate dialogue between carers and professionals with the purpose of assessing carers' support needs.

Selective mutism in children and adolescents. / Selektiv mutisme hos barn og unge.

The diagnosis selective mutism describes children who are completely mute in situations where speech is expected (usually in day-care or school), whereas at home they do speak with close family members. Early intervention is essential, but often a long time may pass before these children are offered adequate help.

Mapping empirical experiences of Tom Kitwood's framework of person-centred care for persons with dementia in institutional settings. A scoping review.

INTRODUCTION: Tom Kitwood's theoretical framework of person-centred care is extensively and internationally referred to in healthcare services. However, despite the broad use of Kitwood's approach in clinical practice, the research examining experiences with the approach has not been mapped. AIM: To map the available literature on current empirical experiences in clinical practice of Kitwood's approach to person-centred care for people with dementia, living in institutional settings in primary health care. METHODS: A total of 154 studies concerning the experiences of people with dementia and their formal caregivers' use of Kitwood's framework of person-centred care for residents living in institutional settings in primary health care were compiled from scientific databases. All three authors engaged in a systematic selection process, leading to nineteen articles being included in the review. RESULTS: The results showed an overall tendency towards positive experiences gained from applying person-centred approaches in clinical practice influenced by Kitwood's theoretical framework. Through the synthesis of data from the selected studies, six categories related to our research aim were identified 'Theoretical evaluation of Tom Kitwood's model of care', 'Models and frameworks', 'Interventions', 'Communication', 'Dementia Care Mapping' and 'Environment'. CONCLUSION: The present review included nineteen studies published from 1998 to 2016 and consisted mainly of peer-reviewed scientific articles, followed by dissertations, conference posters and nonpeer-reviewed articles. All studies were undertaken in Western countries. The vast majority of the studies considered Kitwood's theoretical framework to be beneficial and useful in practice.

An occupation-based intervention in patients with hand-related disorders grouped using the sense of coherence scale-A randomized controlled trial.

STUDY DESIGN: A nonblinded randomized controlled trial. INTRODUCTION: Occupation-based interventions are superior to physical exercise-based interventions in patients with activity limitations. However, only a few studies have examined the effect in patients with hand-related disorders. Patients recover heterogeneously, which could be due to personal factors, such as sense of coherence (SOC). PURPOSE OF THE STUDY: To investigate the effectiveness of an occupation-based intervention for patients with hand-related disorders and whether SOC can give an indication of the expected effects. METHODS: A total of 504 patients were stratified into three SOC groups and then randomized to either an occupation-based intervention, including physical exercises (OBI) or a physical exercise-based occupation-focused intervention. The primary outcome, functioning, was measured using the Disability of the Arm, Shoulder and Hand questionnaire. Primary endpoint was at three months. Patients were followed up for a year. RESULTS: No significant difference was found in primary outcome analysis. Nevertheless, patients receiving OBI had a statistically significant and greater change in satisfaction with their occupational performance at one, two, and three months follow-up. Patients with a weak SOC had worse functioning and lower health-related quality of life than those in the other groups, at all times. CONCLUSIONS: OBI as delivered in this study was not superior to physical exercise-based occupation-focused intervention in this patient group. However, in taking a client-centered approach, we recommend that OBI be based on individual needs, given that patients had a statistically greater change in score regarding satisfaction with their occupational performance. It is evident that patients with a weaker SOC have a lower level of functioning. This knowledge should inform clinical practice.

Methods for teaching evidence-based practice: a scoping review.

BACKGROUND: This scoping review aims to gather and map inspiration, ideas and recommendations for teaching evidence-based practice across Professional Bachelor Degree healthcare programmes by mapping literature describing evidence-based practice teaching methods for undergraduate healthcare students including the steps suggested by the Sicily Statement. METHODS: A computer-assisted literature search using PubMed, Cinahl, PsycINFO, and OpenGrey covering health, education and grey literature was performed. Literature published before 2010 was excluded. Students should be attending either a Professional Bachelor's degree or a Bachelor's degree programme. Full-text articles were screened by pairs of reviewers and data extracted regarding: study characteristics and key methods of teaching evidence-based practice. Study characteristics were described narratively. Thematic analysis identified key methods for teaching evidence-based practice, while full-text revisions identified the use of the Sicily Statement's five steps and context. RESULTS: The database search identified 2220 records. One hundred ninety-two records were eligible for full-text assessment and 81 studies were included. Studies were conducted from 2010 to 2018. Approximately half of the studies were undertaken in the USA. Study designs were primarily qualitative and participants mainly nursing students. Seven key methods for teaching evidence-based practice were identified. Research courses and workshops, Collaboration with clinical practice and IT technology were the key methods most frequently identified. Journal clubs and Embedded librarians were referred to the least. The majority of the methods included 2-4 of the Sicily Statement's five steps, while few methods referred to all five steps. CONCLUSIONS: This scoping review has provided an extensive overview of literature describing methods for teaching EBP regarding undergraduate healthcare students. The two key methods Research courses and workshops and Collaboration with clinical practice are advantageous methods for teaching undergraduate healthcare students evidence-based practice; incorporating many of the Sicily Statement's five steps. Unlike the Research courses and workshop methods, the last step of evaluation is carried out partly or entirely in a clinical context. Journal clubs and Embedded librarians should be further investigated as methods to reinforce existing methods of teaching. Future research should focus on methods for teaching EBP that incorporate as many of the five steps of teaching and conducting EBP as possible.

Treatment of selective mutism: a 5-year follow-up study.

Selective mutism (SM) has been defined as an anxiety disorder in the diagnostic and statistical manual of mental disorders (DSM-5). Cognitive behavioral therapy (CBT) is the recommended approach for SM, but prospective long-term outcome studies are lacking. Reports from the children themselves, and the use of more global quality of life measures, are also missing in the literature. We have developed a school-based CBT intervention previously found to increase speech in a pilot efficacy study and a randomized controlled treatment study. Continued progress was found in our 1-year follow-up studies, where older age and more severe SM had a significant negative effect upon outcome. In the present study, we provide 5-year outcome data for 30 of these 32 children with SM who completed the same CBT for mean 21 weeks (sd 5, range 8-24) at mean age 6 years (10 boys). Mean age at the 5-year follow-up was 11 years (range 8-14). Outcome measures were diagnostic status, the teacher- and parent-rated selective mutism questionnaires, and child rated quality of life and speaking behavior. At the 5-year follow-up, 21 children were in full remission, five were in partial remission and four fulfilled diagnostic criteria for SM. Seven children (23%) fulfilled criteria for social phobia, and separation anxiety disorder, specific phobia and/or enuresis nocturna were found in a total of five children (17%). Older age and severity at baseline and familial SM were significant negative predictors of outcome. Treatment gains were maintained on the teacher- and parent questionnaires. The children rated their overall quality of life as good. Although most of them talked outside of home, 50% still experienced it as somewhat challenging. These results point to the long-term effectiveness of CBT for SM, but also highlight the need to develop more effective interventions for the subset of children with persistent symptoms.Clinical trials registration NCT01002196.

Neurodevelopmental disorders: prevalence and comorbidity in children referred to mental health services.

BACKGROUND: Accurate prevalence rates of the neurodevelopmental disorders (ND) and comorbid conditions in child and adolescent mental health services (CAMHS) are essential for treatment planning and organization of health care. However, valid and reliable prevalence estimates from Nordic CAMHS populations are scarce, and the published findings vary. AIMS: To report prevalence rates of ND (attention-deficit hyperactivity disorder: ADHD, tic disorder: TD or autism spectrum disorder: ASD) and comorbid disorders by a validated diagnostic instrument in children referred to CAMHS outpatient clinics. METHODS: Parents of 407 consecutively referred children aged 7-13 years were interviewed with the semistructured interview schedule for affective disorders and schizophrenia, present and lifetime version (Kiddie-SADS-PL) at time of admittance. RESULTS: One or more ND was diagnosed in 226 children (55.5%; 69.9% boys): ADHD (44.5%; 68.5% boys); TD (17.7%; 77.8% boys) and ASD (6.1%; 76% boys). Among children with ND 70 (31.0%) had only one ND with no comorbid disorder, 49 (21.7%) had more than one ND (homotypic comorbidity) and 131 (58%) had a non-ND psychiatric disorder (heterotypic comorbidity). Anxiety disorders were the most frequently occurring heterotypic comorbidity in all three ND. Comorbid depressive disorder was associated with older age, and comorbid anxiety disorder with female gender. CONCLUSION: In children referred to CAMHS, ND constitute the most frequently occurring group of disorders, with high rates of both homotypic and heterotypic comorbidity. This needs to be taken into consideration in health service planning and treatment delivery.

Non-obsessive-compulsive anxiety disorders in child and adolescent mental health services--Are they underdiagnosed, and how accurate is referral information?

BACKGROUND: Previous studies have reported low prevalence of non-obsessive-compulsive (OCD) anxiety disorders in child and adolescent mental health services (CAMHSs), suggesting that these disorders may go unrecognized. Possible reasons may be lack of routinely used standardized diagnostic instruments, and/or an under-reporting of anxiety symptoms in the referral information. AIMS: To examine the frequency of non-OCD anxiety disorders in referred children based on a standardized diagnostic interview, to compare the results with data from the Norwegian Patient Register (NPR), and to explore the correspondence between anxiety as a referral symptom and anxiety as a diagnosis, and the influence of heterotypic co-morbidity on this correspondence. METHODS: Parents of 407 consecutive referrals to CAMHS aged 7-13 years were interviewed with the semi-structured diagnostic interview Kiddie-SADS-PL at the time of admittance. Referral symptoms were collected from national referral forms. RESULTS: A total of 133 referred children (32.7%) met the criteria for a non-OCD anxiety disorder compared with about 5% in the NPR. Half of those who met diagnostic criteria for an anxiety disorder did not have anxiety as a referral symptom. Co-morbid ADHD or disruptive disorder was significantly associated with a lower probability of having anxiety as a referral symptom. CONCLUSIONS: The use of a standardized diagnostic interview in consecutively referred children yielded significantly higher rates of anxiety disorders than the NPR prevalence rates. Co-morbid ADHD or disruptive disorder may contribute to the underdiagnosing of anxiety disorders. Diagnostic instruments covering the whole range of child psychiatric symptoms should be implemented routinely in CAMHS.

Convergent and divergent validity of K-SADS-PL anxiety and attention deficit hyperactivity disorder diagnoses in a clinical sample of school-aged children.

Background The Schedule for Affective Disorders and Schizophrenia for School Age Children, Present and Lifetime Version (K-SADS-PL) is a commonly used diagnostic interview both in research and clinical settings, yet published data on the psychometric properties of the interview generated diagnoses are scarce. Aims To examine the convergent and divergent validity of the Norwegian version of the K-SADS-PL current diagnoses of anxiety disorders and attention deficit hyperactivity disorder (ADHD). Method Participants were 105 children aged 7-13 years referred for treatment at child mental health clinics and 36 controls. Diagnostic status was determined based on K-SADS-PL interviews with the mothers. Child and mother reported child symptoms of anxiety on the Multidimensional Anxiety Scale for Children and teachers reported anxiety symptoms on the Teacher Report Form. Mother and teacher reported on symptoms of ADHD on the Disruptive Behavior Rating Scale. Results Rating scale data from multiple informants in a clinical sample and healthy controls supported the convergent and divergent validity of K-SADS-PL anxiety diagnoses combined, and, specifically, the diagnoses of separation anxiety disorder, social phobia, and specific phobia. Support was also observed for convergent and divergent validity of ADHD diagnoses, including the predominately inattentive subtype. Conclusion The K-SADS-PL generates valid diagnoses of anxiety disorders and ADHD.

Root isolations of Metarhizium spp. from crops reflect diversity in the soil and indicate no plant specificity.

Metarhizium spp. have recently been shown to be associated with the roots of different plants. Here we evaluated which Metarhizium species were associated with roots of oat (Avena sativa), rye (Secale cereale) and cabbage (Brassica oleracea), common crop plants in Denmark. Thirty-six root samples from each of the three crops were collected within an area of approximately 3ha. The roots were rinsed with sterile water, homogenized and the homogenate plated onto selective media. A subset of 126 Metarhizium isolates were identified to species by sequencing of the 5' end of the gene translation elongation factor 1-alpha and characterized by simple sequence repeat (SSR) analysis of 14 different loci. Metarhizium brunneum was the most common species isolated from plant roots (84.1% of all isolates), while M. robertsii (11.1%) and M. majus (4.8%) comprised the remainder. The SSR analysis revealed that six multilocus genotypes (MLGs) were present among the M. brunneum and M. robertsii isolates, respectively. A single MLG of M. brunneum represented 66.7%, 79.1% and 79.2% of the total isolates obtained from oat, rye and cabbage, respectively. The isolation of Metarhizium spp. and their MLGs from roots revealed a comparable community composition as previously reported from the same agroecosystem when insect baiting of soil samples was used as isolating technique. No specific MLG association with a certain crop was found. This study highlights the diversity of Metarhizium spp. found in the rhizosphere of different crops within a single agroecosystem and suggests that plants either recruit fungal associates from the surrounding soil environment or even govern the composition of Metarhizium populations.

Selective mutism: follow-up study 1 year after end of treatment.

Cognitive behavioral therapy (CBT) is generally considered the recommended approach for selective mutism (SM). Prospective follow-up studies of treated SM and predictors of outcome are scarce. We have developed a CBT home and school-based intervention for children with SM previously found to increase speech in a pilot efficacy study and in a randomized controlled treatment study. In the present report we provide outcome data 1 year after having completed the 6-month course of CBT for 24 children with SM, aged 3-9 years (mean age 6.5 years, 16 girls). Primary outcome measures were the teacher rated School Speech Questionnaire (SSQ) and diagnostic status. At follow-up, no significant decline was found on the SSQ scores. Age and severity of SM had a significant effect upon outcome, as measured by the SSQ. Eight children still fulfilled diagnostic criteria for SM, four were in remission, and 12 children were without diagnosis. Younger children improved more, as 78% of the children aged 3-5 years did not have SM, compared with 33% of children aged 6-9 years. Treatment gain was upheld at follow-up. Greater improvement in the younger children highlights the importance of an early intervention.

Associations between sleep problems and attentional and behavioral functioning in children with anxiety disorders and ADHD.

This study examined associations between sleep problems and attentional and behavioral functioning in 137 children aged 7 to 13 years with anxiety disorders (n = 39), attention deficit hyperactivity disorder (ADHD; n = 38), combined anxiety disorder and ADHD (n = 25), and 35 controls. Diagnoses were made using the semistructured diagnostic interview Schedule for Affective Disorders and Schizophrenia for School-age Children-Present and Lifetime Version. Sleep problems were assessed using the Children's Sleep Habits Questionnaire, attention was measured by the Attention Network Test, and behavioral problems were measured by teacher ratings on the Achenbach System of Empirically Based Assessment, Teacher Report Form. Sleep problems were associated with reduced efficiency of the alerting attention system for all children and with increased internalizing problems in children with anxiety disorders.

Somatic symptoms in children with anxiety disorders: an exploratory cross-sectional study of the relationship between subjective and objective measures.

Symptoms of childhood anxiety disorders include activation of bodily stress systems to fear stimuli, indicating alterations of the autonomic nervous system (ANS). Self-reported somatic symptoms are frequently reported, while studies including objective measures of ANS are scarce and show inconsistent results. Even less studied is the relationship between subjective and objective measures of somatic symptoms in anxious children. Increased knowledge of this relationship may have relevance for treatment programmes for anxiety disorders. This cross-sectional study examined subjective and objective measures of ANS responsiveness in a clinical sample of children with anxiety disorders (7-13 years; n = 23) and in healthy controls (HC; n = 22) with equal distributions of gender and age. The subjective measure used was the Multidimensional Anxiety Scale for Children, which includes a subscale on somatic symptoms. The objective measures consisted of an orthostatic challenge (head-up tilt test), and an isometric muscular exercise (handgrip) while the participants were attached to the Task Force Monitor, a combined hardware and software device used for continuous, non-invasive recording of cardiovascular variables. The anxiety disorder group reported significantly more somatic symptoms than HCs (both by mother and child reports). In contrast, no relevant differences in cardiovascular variables were demonstrated between the anxiety group and HCs. Finally, there were no significant correlations between subjective and objective measures in either group. Because of the small sample size, the findings must be interpreted carefully, but the results do not support previous reports of functional alterations of the ANS in anxious children.

A randomized controlled trial of a home and school-based intervention for selective mutism - defocused communication and behavioural techniques.

BACKGROUND: Randomized controlled psychosocial treatment studies on selective mutism (SM) are lacking. METHOD: Overall, 24 children with SM, aged 3-9 years, were randomized to 3 months treatment (n = 12) or wait list (n = 12). Primary outcome measure was the School Speech Questionnaire. RESULTS: A significant time by group interaction was found (p = .029) with significantly increased speech in the treatment group (p = .004) and no change in wait list controls (p = .936). A time by age interaction favoured younger children (p = .029). Clinical trail registration: Norwegian Research CouncilNCT01002196. CONCLUSIONS: The treatment significantly improved speech. Greater improvement in the younger age group highlights the importance of an early intervention.
