General self-concept and life satisfaction for boys with differing levels of physical coordination: the role of goal orientations and leisure participation

Participation in leisure-time activities, self-concept perceptions and individual dispositional goal orientations were examined as mediators of relationships between physical coordination and self-evaluations of life satisfaction and general self-concept for 173 boys aged 10-13 years. Participants completed seven-day activity diaries and 12-month retrospective recall questionnaires recording participation in leisure-time activities. Self-report measures of self-concept, global life satisfaction and dispositional goal orientations were also completed. Results showed that boys with moderate to severe physical coordination difficulties had significantly lower self-concept perceptions of physical ability and appearance, peer and parent relations and general self-concept, as well as lower life satisfaction than boys with medium to high levels of physical coordination. The relationships between boys' physical coordination and their self-perceptions of life satisfaction and general self-concept were significantly influenced by individual self-concept appraisals of physical ability and appearance, peer and parent relations. Adopting task-oriented goals was found to positively change the relationship between physical coordination and both general self-concept and life satisfaction. Team sport participation positively mediated the relationship between physical coordination and life satisfaction. The potential for team sport participation and adoption of task-oriented goals to influence life satisfaction for boys with differing levels of physical coordination was discussed.     

How school-based dancing classes change affective and collaborative networks of adolescents

ObjectiveThe present research investigated the effects of adolescents' co-participation in a federally funded dance intervention project on students' affective and collaborative networks. In the intervention, students instructed by professional dancers collaboratively developed a dance-choreography during regular class hours in student groups. We expected that the number of reciprocated affective and collaborative ties should increase in classrooms participating in the intervention, but that boys should particularly benefit from the intervention.DesignWe used a quasi-experimental untreated control group design with dependent pretest and posttest samples. Participants were 421 youths (48% boys) in 23 classrooms of primary and secondary schools in Berlin, Germany. Of these, 226 (54%) participated in the intervention. Classrooms from the same grade and school were recruited as comparison groups. We assessed both networks using sociometric questionnaires.Method/ResultsWe found a significant Treatment × Gender interaction showing that reciprocated collaborative relations increased only for boys in the intervention group. Analyses probing potential mechanisms showed this was due to their choosing more collaboration partners, in particular more girls.ConclusionFindings suggest that school-based dancing programs encouraging coordinated physical activity in student groups may be particularly beneficial for boys, encouraging them to consider girls as academic cooperation partners and to proactively develop their collaborative networks.     

Parent-carer awareness and understanding of dyspraxia: Implications for child development support practices

Dyspraxia manifests as difficulty in thinking, planning, and executing planned movements or tasks. Dyspraxia affects roughly 5–6% of school aged children. This study aimed to explore parent-carer’s awareness and understanding of dyspraxia and the resources they self-perceived to need to manage their children with dyspraxia. Informants were 15 parents from the Cape Peninsula, South Africa. They completed semi-structured interviews on their knowledge of and indicators of dyspraxia in their children and resources they presently utilised or could seek to use. Thematic analysis of the data suggested the parent-carers to be aware of motor rather than cognition oriented limitations. Additionally, parent-carers accessed or sought educator assistance from the school system. Health professionals and educators working with parents of children with dyspraxia can expect them to report reliably on behavioural characteristics of their children’s abilities important for treatment support interventions.     

Responsible Alcoholic Beverages Sales and Services Training Intervention in Cape Town: A Pilot Study

The aim of this study was to pilot a responsible beverage service intervention in order to reduce alcohol-impaired road use. The sample included 20 shebeens including 10 licensed and 10 unlicensed establishments chosen from a list of alcohol serving establishments in Gugulethu, Cape Town. The study examined whether changes in knowledge, attitudes, and behaviour of servers as well as BAC levels of patrons occurred as a result of receiving server intervention training. Results indicate that the training programme was effective in changing serving practices consistent with the techniques and strategies emphasized in the training. However, the breathalyser results for baseline and follow-up, respectively, in the intervention and control group did not show differences among patrons. It is recommended that mandatory server training be introduced in South Africa for licensed establishments and develop an incentive system to encourage voluntary use of server training for unlicensed establishments.     

Detrimental psychological outcomes associated with pubertal timing in adolescent boys

Though often discussed as a discrete event, puberty comprises one segment of a larger developmental continuum and is notable for rapid transformation across a multitude of domains. While an earlier timing of puberty relative to peers stands as one of the most well-replicated antecedents of adolescent difficulties for girls, findings have been less consistent for boys’ development. The current review synthesizes the research on pubertal timing and psychosocial development in adolescent boys. Results are evaluated in the context of three theoretical perspectives by which precocious development is believed to affect the emergence of adverse outcomes: biological, psychosocial and selection.     

Effects of school-based interventions on motivation towards physical activity in children and adolescents: A systematic review and meta-analysis

IntroductionAssuming that motivation is the key to initiate and sustain beneficial health behaviors, the aim of this systematic review was to analyze the effects of school-based physical activity interventions on a variety of motivational outcomes towards PA in school-aged children and adolescents.MethodsA comprehensive literature search was carried out in six electronic databases to identify randomized controlled trials and quasi-experimental trials examining the effects of PA interventions implemented during the regular school day, e.g., during physical education lessons or lunch breaks. Primary outcomes of interest were students' motivation, basic psychological needs, goal orientation, enjoyment, and motivational teaching climate in physical education. Meta-analyses were conducted for these outcomes using Comprehensive Meta-analysis software. Secondarily, intervention effects on students' PA behaviors were examined and the findings summarized narratively. Methodological quality of studies was evaluated using the Cochrane Collaboration's tool for assessing risk of bias for randomized trials; certainty of evidence on outcome level was evaluated using the GRADE approach.ResultsIn total, 57 studies carried out between 2001 and 2018 were included in this review. Sixteen individual meta-analyses were performed and revealed significant pooled effects for the outcomes enjoyment (g = 0.310), perceived autonomy (g = 0.152), identified regulation (g = 0.378), intrinsic motivation (g = 0.419), self-determination index (g = 0.672), task/mastery climate (g = 0.254), ego/performance climate (g = −0.438), autonomy supportive climate (g = 0.262), task goal orientation (g = 1.370), ego goal orientation (g = −0.188). The narrative data synthesis indicated an increase in students' PA behavior. The overall risk of bias was high across all studies and certainty of evidence of meta-analyzed outcomes ranged from very low to moderate. Moderate certainty of evidence was found for ego/performance climate and ego goal orientation. Conclusions: Meta-analyses suggest that school-based PA interventions may be effective in increasing a variety of motivational outcomes. However, the certainty of evidence was limited in the majority of outcomes. Further research is needed to identify effective intervention strategies that increase students’ motivation towards PA.     

Managing dyspraxia: Pre-school teachers’ perceptions,experiences and strategies

Dyspraxia is a childhood developmental disorder that manifests as a difficulty in thinking, planning, and executing planned movements or tasks. Dyspraxia affects approximately 5–6% of school-aged children. This study aimed to explore pre-school teachers’ awareness and understanding of dyspraxia, and the support they desire for teaching children with dyspraxia. Informants were 15 pre-school teachers from the Cape Peninsula, South Africa (black = 1; coloured/mixed race = 13; white = 1). The teachers completed semi-structured interviews regarding their awareness and knowledge of dyspraxia and the support they require to better facilitate the learners’ development. A thematic analysis of the data suggested that the teachers were aware of the behavioural and cognitive difficulties associated with dyspraxia and that they need to seek professional development to enhance their management of children with dyspraxia. Early intervention strategies, in partnership with the parent carers of the children, appear to hold good prospects for the successful management of dyspraxia among school-aged children.     

Attention of 4-month infants to discrepancy and babyishness

A set of four facial stimuli derived from the Bolton standards of craniofacial development representing a human male at 6 months, 3, 8, and 18 years of age were used in a test of Lorenz's concept of babyishness and of the discrepancy hypothesis. Each 4-month-old subject was habituated to a criterion with one of the four stimuli and then presented with one of the four as a new stimulus. The design and analysis permitted the response to a new stimulus to be broken down into a component attributable to the physical characteristics of the new stimulus and a part attributable to its discrepancy from the familiar standard. The data revealed longer looking at the infant facial stimulus, but no difference in a rating of affect accompanying fixation. This lent partial support to the babyishness concept for infant subjects. Both fixation and affect increased monotonically with magnitude of discrepancy. The increasing rather than curvilinear result presumably derived from the failure of these stimuli (which were common to the infant's experience) to generate extreme levels of subjective uncertainty.
