The validity and reliability of school-based fundamental movement skills screening to identify children with motor difficulties.

AIM: Assess whether school-based teacher-led screening is effective at identifying children with motor difficulties. METHODS: Teachers tested 217 children aged between 5 and 11 years old, after a one hour training session, using a freely available tool (FUNMOVES). Four classes (n = 91) were scored by both researchers and teachers to evaluate inter-rater reliability. Researchers assessed 22 children using the Movement Assessment Battery for Children (MABC-2; considered to be the 'gold standard' in Europe for use as part of the diagnostic process for Developmental Coordination Disorder) to assess concurrent and predictive validity. RESULTS: Inter-rater reliability for all individual activities within FUNMOVES ranged from 0.85-0.97 (unweighted Kappa; with 95%CI ranging from 0.77-1). For total score this was lower (κ = 0.76, 95%CI = 0.68-0.84), however when incorporating linear weighting, this improved (κ = 0.94, 95%CI = 0.89-0.99). When evaluating FUNMOVES total score against the MABC-2 total score, the specificity (1, 95%CI = 0.63-1) and positive predictive value (1; 95%CI = 0.68-1) of FUNMOVES were high, whereas sensitivity (0.57, 95%CI = 0.29-0.82) and negative predictive values (0.57, 95%CI = 0.42-0.71) were moderate. Evaluating only MABC-2 subscales which are directly related to fundamental movement skills (Aiming & Catching, and Balance) improved these values to 0.89 (95%CI = 0.52-1) and 0.93 (95%CI = 0.67-0.99) respectively. INTERPRETATION: Teacher-led screening of fundamental movement skills (via FUNMOVES) is an effective method of identifying children with motor difficulties. Such universal screening in schools has the potential to identify movement difficulties and enable earlier intervention than the current norm.

The impact of Allied Health Professionals on the primary and secondary prevention of obesity in young children: A scoping review.

Allied Health Professionals (AHPs) have the capacity to promote healthy behaviours in young children through routine 'contact points', as well as structured weight management programmes. This scoping review aims to evaluate the impact of AHPs in the prevention of obesity in young children. Databases were searched for relevant evidence between 1st January 2000 and 17th January 2022. Eligibility criteria included primary evidence (including, but not limited to; randomized controlled trials, observational studies, service evaluations) evaluating the impact of AHPs on the primary and secondary prevention of obesity in young children (mean age under 5 years old). AHP-related interventions typically demonstrated improvements in outcomes such as nutritional behaviour (e.g. lower sweetened drink intake), with some reductions in screen time. However, changes in weight outcomes (e.g. body mass index (BMI) z-score, BMI) in response to an AHP intervention were inconsistent. There was insufficient data to determine moderating effects, however tentative evidence suggests that those with a lower socioeconomic status or living in an underprivileged area may be more likely to lose weight following an AHP intervention. There was no evidence identified evaluating how AHPs use routine 'contact points' in the prevention of obesity in young children. AHP interventions could be effective in optimizing weight and nutritional outcomes in young children. However, more research is required to determine how routine AHP contact points, across the range of professional groups may be used in the prevention of obesity in young children.

Advancing cluster randomised trials in children's therapy: a survey of the acceptability of trial behaviours to therapists and parents.

BACKGROUND: Randomised controlled trials of non-pharmacological interventions in children's therapy are rare. This is, in part, due to the challenges of the acceptability of common trial designs to therapists and service users. This study investigated the acceptability of participation in cluster randomised controlled trials to therapists and service users. METHODS: A national electronic survey of UK occupational therapists, physiotherapists, speech and language therapists, service managers, and parents of children who use their services. Participants were recruited by NHS Trusts sharing a link to an online questionnaire with children's therapists in their Trust and with parents via Trust social media channels. National professional and parent networks also recruited to the survey. We aimed for a sample size of 325 therapists, 30 service managers, and 60 parents. Trial participation was operationalised as three behaviours undertaken by both therapists and parents: agreeing to take part in a trial, discussing a trial, and sharing information with a research team. Acceptability of the behaviours was measured using an online questionnaire based on the Theoretical Framework of Acceptability constructs: affective attitude, self-efficacy, and burden. The general acceptability of trials was measured using the acceptability constructs of intervention coherence and perceived effectiveness. Data were collected from June to September 2020. Numerical data were analysed using descriptive statistics and textual data by descriptive summary. RESULTS: A total of 345 survey responses were recorded. Following exclusions, 249 therapists and 40 parents provided data which was 69.6% (289/415) of the target sample size. It was not possible to track the number of people invited to take the survey nor those who viewed, but did not complete, the online questionnaire for calculation of response rates. A completion rate (participants who completed the last page of the survey divided by the participants who completed the first, mandatory, page of the survey) of 42.9% was achieved. Of the three specified trial behaviours, 140/249 (56.2%) therapists were least confident about agreeing to take part in a trial. Therapists (135/249, 52.6%) reported some confidence they could discuss a trial with a parent and child at an appointment. One hundred twenty of 249 (48.2%) therapists reported confidence in sharing information with a research team through questionnaires and interviews or sharing routine health data. Therapists (140/249, 56.2%) felt that taking part in the trial would take a lot of effort and resources. Support and resources, confidence with intervention allocation, and sense of control and professional autonomy over clinical practice were factors that positively affected the acceptability of trials. Of the 40 parents, twelve provided complete data. Most parents (18/40, 45%) agreed that it was clear how trials improve children's therapies and outcomes and that a cluster randomised trial made sense to them in their therapy situation (12/29, 30%). CONCLUSIONS: Using trials to evaluate therapy interventions is, in principle, acceptable to therapists, but their willingness to participate in trials is variable. The willingness to participate may be particularly influenced by their views related to the burden associated with trials, intervention allocation, and professional autonomy.

Occupational Lives in Sustained Recovery From Alcohol Dependency: An Interpretive Phenomenological Analysis.

Alcohol use is a significant risk factor for ill health. Although many people complete treatment, only one third maintain their sobriety. Research has suggested that occupational engagement supports early recovery, but its role in sustained recovery is not known. This study aimed to explore the occupational lives of individuals in sustained recovery from alcohol dependency. An interpretive phenomenological analysis methodology was used, utilizing an occupational perspective. Participants were recruited from a substance use recovery center. Data were collected through interviews and analyzed thematically. This study had three participants. Four themes emerged: (a) shaping occupational lives, (b) shifting coping strategies, (c) finding a gateway to new social connections and a sense of belonging, and (d) establishing a new role in the context of recovery. Findings suggest that in sustained recovery, occupations develop new meanings and purposes that have the potential to support recovery.

Social participation to support good mental health in neurodisability.

BACKGROUND: Young people with neurodisability experience lower levels of mental wellbeing and are at increased risk of mental illness compared with their non-disabled peers. Social participation is recognized as a protective factor against mental illness and a potential pathway to support better mental wellbeing in neurodisability. METHOD: This co-design study involved young people, parents and clinicians. First, possible interventions were identified through a rapid systematic evidence review. Any study designs were considered, which included people with a neurodisability aged 0-18 years, which evaluated a therapy intervention with social participation and mental health outcomes. Titles and abstracts were screened by two reviewers, from the included studies data were extracted and then presented using written summaries. Second, the summaries were discussed and prioritized in stakeholder groups with young people, parents and clinicians. Groups were audio recorded and framework analysis was used to identify and specify intervention elements and their delivery. RESULTS: The evidence review identified 13,870 records, from which 43 were included. These records were published 1994-2017 and reported studies with 4-249 participants aged 16 months-18 years with a range of neurodisabilities. Five intervention approaches (social skills training, arts, sports, technology and play) were identified from the review. Two themes emerged from the stakeholder groups: intervention in the real world, feeling judged and feeling safe. The groups prioritized an intervention in real-world social leisure contexts (i.e. existing clubs and groups) using nine key intervention elements (e.g. feedback and positive verbal reinforcement) delivered by club leaders trained by healthcare professionals using five intervention procedures (e.g. a manual and video training). CONCLUSION: This study has identified core elements of social participation interventions that may improve mental health outcomes in young people with neurodisability, which should now be tested.

Definitions and Operationalization of Mental Health Problems, Wellbeing and Participation Constructs in Children with NDD: Distinctions and Clarifications.

Children with impairments are known to experience more restricted participation than other children. It also appears that low levels of participation are related to a higher prevalence of mental health problems in children with neurodevelopmental disorders (NDD). The purpose of this conceptual paper is to describe and define the constructs mental health problems, mental health, and participation to ensure that future research investigating participation as a means to mental health in children and adolescents with NDD is founded on conceptual clarity. We first discuss the difference between two aspects of mental health problems, namely mental disorder and mental illness. This discussion serves to highlight three areas of conceptual difficulty and their consequences for understanding the mental health of children with NDD that we then consider in the article: (1) how to define mental health problems, (2) how to define and assess mental health problems and mental health, i.e., wellbeing as separate constructs, and (3) how to describe the relationship between participation and wellbeing. We then discuss the implications of our propositions for measurement and the use of participation interventions as a means to enhance mental health (defined as wellbeing). Conclusions: Mental disorders include both diagnoses related to impairments in the developmental period, i.e., NDD and diagnoses related to mental illness. These two types of mental disorders must be separated. Children with NDD, just like other people, may exhibit aspects of both mental health problems and wellbeing simultaneously. Measures of wellbeing defined as a continuum from flourishing to languishing for children with NDD need to be designed and evaluated. Wellbeing can lead to further participation and act to protect from mental health problems.

Why Do You Ride?: A Characterization of Mountain Bikers, Their Engagement Methods, and Perceived Links to Mental Health and Well-Being.

Mountain biking is an increasingly popular outdoor activity on the extreme sport continuum. Extreme and high-risk sports have been investigated using a variety of motivational theories with sensation seeking a dominant theme; however, behavioral and motivational homogeneity within these types of populations should not be assumed. Recent studies have highlighted the therapeutic potential of extreme sports and similar outdoor activities. The aim of this study was to describe the characteristics of mountain biking participants, their engagement methods, and perceived benefits to mental health and well-being. This was a cross-sectional survey and participants were recruited via social media. An online questionnaire specific to the domain of mountain biking was developed. Analysis of the full sample (n = 1,484) and of three independent paired sub-samples was conducted using SPSS. The sub-samples compared the results of males and females; younger and older riders; and those who have recently engaged in downhill mountain biking and those who have not. The results have succeeded in identifying some disparities in mountain biker characteristics and engagement methods. The results suggest that some riders found pleasure in higher risk engagement. The study proposes various explanations for the disproportion of women in mountain biking. Irrespective of the confounding factors related to rider characteristics or engagement methods, mountain bikers reported copious benefits to mental health and well-being related to their engagement. There was a high reported usage of mountain biking as a coping strategy. As such, this study provides insights that could inform the development of outdoor activities as interventions for mental health.

Selective enrichment and sequencing of whole mitochondrial genomes in the presence of nuclear encoded mitochondrial pseudogenes (numts).

Numts are an integral component of many eukaryote genomes offering a snapshot of the evolutionary process that led from the incorporation of an α-proteobacterium into a larger eukaryotic cell some 1.8 billion years ago. Although numt sequence can be harnessed as molecular marker, these sequences often remain unidentified and are mistaken for genuine mtDNA leading to erroneous interpretation of mtDNA data sets. It is therefore indispensable that during the process of amplifying and sequencing mitochondrial genes, preventive measures are taken to ensure the exclusion of numts to guarantee the recovery of genuine mtDNA. This applies to mtDNA analyses in general but especially to studies where mtDNAs are sequenced de novo as the launch pad for subsequent mtDNA-based research. By using a combination of dilution series and nested rolling circle amplification (RCA), we present a novel strategy to selectively amplify mtDNA and exclude the amplification of numt sequence. We have successfully applied this strategy to de novo sequence the mtDNA of the Black Field Cricket Teleogryllus commodus, a species known to contain numts. Aligning our assembled sequence to the reference genome of Teleogryllus emma (GenBank EU557269.1) led to the identification of a numt sequence in the reference sequence. This unexpected result further highlights the need of a reliable and accessible strategy to eliminate this source of error.

Heritable pollution tolerance in a marine invader.

The global spread of fouling invasive species is continuing despite the use of antifouling biocides. Furthermore, previous evidence suggests that non-indigenous species introduced via hull fouling may be capable of adapting to metal-polluted environments. Using a laboratory based toxicity assay, we investigated tolerance to copper in the non-indigenous bryozoan Watersipora subtorquata from four source populations. Individual colonies were collected from four sites within Port Hacking (Sydney, Australia) and their offspring exposed to a range of copper concentrations. This approach, using a full-sib, split-family design, tests for a genotype by environment (G×E) interaction. Settlement and complete metamorphosis (recruitment) were measured as ecologically relevant endpoints. Larval sizes were also measured for each colony. Successful recruitment was significantly reduced by the highest copper concentration of 80µgL(-1). While there was no difference in pollution tolerance between sites, there was a significant G×E interaction, with large variation in the response of colony offspring within sites. Larval size differed significantly both between sites and between colonies and was positively correlated with tolerance. The high level of variation in copper tolerance between colonies suggests that there is considerable potential within populations to adapt to elevated copper levels, as tolerance is a heritable trait. Also, colonies that produce large larvae are more tolerant to copper, suggesting that tolerance may be a direct consequence of larger size.

Quantifying male attractiveness.

Genetic models of sexual selection are concerned with a dynamic process in which female preference and male trait values coevolve. We present a rigorous method for characterizing evolutionary endpoints of this process in phenotypic terms. In our phenotypic characterization the mate-choice strategy of female population members determines how attractive females should find each male, and a population is evolutionarily stable if population members are actually behaving in this way. This provides a justification of phenotypic explanations of sexual selection and the insights into sexual selection that they provide. Furthermore, the phenotypic approach also has enormous advantages over a genetic approach when computing evolutionarily stable mate-choice strategies, especially when strategies are allowed to be complex time-dependent preference rules. For simplicity and clarity our analysis deals with haploid mate-choice genetics and a male trait that is inherited phenotypically, for example by vertical cultural transmission. The method is, however, easily extendible to other cases. An example illustrates that the sexy son phenomenon can occur when there is phenotypic inheritance of the male trait.
