Muscular fitness,motor competence,and processing speed in preschool children

ABSTRACT

The aim of this study was to examine the relationship between muscular fitness and motor competence and processing speed in preschool children. Eighty-four preschool-aged children were recruited and underwent assessments for muscular fitness (muscular endurance and power), motor competence, and then participated in an auditory oddball task. The findings showed that muscular fitness and motor competence were associated with shorter reaction times after controlling for confounding factors. These findings provide tentative support for a positive association between muscular fitness and motor competence and processing speed in preschool children.

Effect of a motor skill-based intervention in the relationship of individual and contextual factors in children with and without Developmental Coordination Disorder from low-income families

Contextual opportunities facilitate skill acquisition, and the interaction between individual and contextual factors is fundamental to enhancing health and social parameters in children with DCD. This study examined (1) the influence of Mastery Motivational Climate (MMC) and Exercise Play Climate (EPC) interventions on motor performance, physical activity, self-perceptions, BMI, engagement in the lessons, playtime, and screen time of children without and with DCD, (2) the relationship between motor performance, self-perceptions, BMI, engagement in the physical education lessons, playtime, and screen factors in the children's physical activity levels in the lessons (PA) pre-and post-test. Children (N = 255, 98 children with Developmental Coordination Disorder - DCD; 157 children without DCD) were randomly assigned to MMC and EPC. Physical Activity levels in the lessons, motor performance, self-perceptions of physical competence, body mass indexes, appropriate motor engagement with success in the lessons, and active play and screen time were assessed. Regarding intervention impact, from pre-to post-tests, the results showed increases (1) PA in children with DCD in the EPC group and without DCD in the MMC group; (2) locomotor and ball skills for children with DCD in both climates; (3) locomotor and ball skills for children without DCD in the MMC group; (4) self-perceptions of competence for children with DCD in the MMC group; and (5) engagement with success for all children in both climates. A slight decrease in BMI for children with DCD in both climates was found. Regarding the associations, at post-test, engagement with success explained (1) PA levels for children with DCD in the MMC group and children without DCD in the EPC group; (2) active playtime explained PA for children with DCD in the EPC group; (3) ball skills explained PA for children without DCD in the MMC group. The intervention promoted overall increases in motor performance and children’s engagement in the lesson. The intervention strengthened the role of ball skills performance, engagement with success, and active play; however, these relationships were different across groups.     

Configurations of actual and perceived motor competence among children: Associations with motivation for sports and global self-worth

The present study used a person-centred approach to examine whether different profiles based on actual and perceived motor competence exist in elementary school children. Multilevel regression analyses were conducted to explore how children with different motor competence-based profiles might differ in their autonomous motivation for sports and global self-worth. Validated questionnaires were administered to 161 children (40% boys; age = 8.82 ± 0.66 years) to assess their perceived motor competence, global self-worth, and motivation for sports. Actual motor competence was measured with the Körperkoordinationstest für Kinder. Cluster analyses identified four motor competence-based profiles: two groups were characterized by corresponding levels of actual and perceived motor competence (i.e., low–low and high–high) and two groups were characterized by divergent levels of actual and perceived motor competence (i.e., high–low and low–high). Children in the low–low and high–low group displayed significantly lower levels of autonomous motivation for sports and lower levels of global self-worth than children in the low–high and high–high group. These findings emphasize that fostering children’s perceived motor competence might be crucial to improve their motivation for sports and their global self-worth. Teachers and instructors involved in physical education and youth sports should thus focus on both actual and perceived motor competence.     

Psychosocial and health-related characteristics of religious well-being

This investigation examined the relationship between religions well-being and eight psychosocial and health-related characteristics. This study assessed the hypothesis that religious well-being is related to overall health. Participants were 462 college students at two separate colleges in the Pacific Northwest. Analysis showed those subjects scoring higher on the measure of religious well-being scored lower on indices like loneliness and hopelessness and higher on self-esteem. Alcohol and drug use also differed significantly between the high and the low, religious well-being groups.     

Association Between Body Mass Index and Motor Competence in Santal Children of Purulia District,India

The purpose of this study was to evaluate the relationship between body mass index and motor competence in Santal children 5–12 years old. A total of 816 Santal children were studied. Children's adiposity status was assessed by body mass index (BMI) for age z-score based on World Health Organization reference data. Motor competence was measured using the Bruininks-Oseretsky Test of Motor Competence (BOT-2). There was no significant difference in mean BMI z-score between Santal boys (0.13 ± 0.07) and girls (?0.14 ± 0.07). Healthy weight (HW) children scored higher (p < .05) in some individual motor subtests (bilateral competence, balance, running speed and agility, upper limb competence, and strength) and in total BOT-2 score (p < .05) compared with scores for underweight (UW) and overweight (OW) children. Nonlinear regression analysis showed that BMI is a significant independent predictor of motor competence (p < .01). Motor competence showed a curvilinear relationship with BMI-z-score, with the lowest point motor scores in strength and upper limb competence (p < .05) for both UW and OW children compared to HW children who scored highest. The results also indicated that gross motor skills, but not fine motor skills, were poorer among children who were UW or OW compared with HW children.     

Visuomotor adaptation and its relationship with motor ability in children with and without autism spectrum disorder

The high prevalence rates of motor impairments among individuals with autism spectrum disorder (ASD) lead to increased attention to motor learning. The current study examined the visuomotor adaptability in children with and without ASD using a computerized visuomotor adaptation task in which the real-time visual feedback of hand movement was rotated. The relationships between visuomotor adaptability and clinical symptomology were also investigated. Results revealed that the children with ASD showed a slower rate of improvement and smaller after-effects than their peers on the measures of motor planning. Additionally, autistic characteristics significantly moderated the association between individuals' adaptability and fine motor skills. The findings contribute to the growing evidence of compromised visuomotor adaptability, which suggested the importance of addressing these clinical features of ASD.     

Interest congruency as a moderator of the relationships between job tenure and job satisfaction and mental health

The purpose of the present study was to examine the role of interest-present job congruency as a moderator of the relationship between job tenure and job satisfaction and mental health. In a sample of 54 middle managers, significant moderator effects were found for the mental health indices of self-esteem, life-satisfaction, and overall mental health and for satisfaction with supervision. As expected, these indices correlated positively with job tenure for high congruency individuals. For low congruency individuals, the relationships were expected to be negative. However, the obtained correlations did not differ significantly from zero.     

The relationship between fine and gross motor ability, self-perceptions and self-worth in children and adolescents

The present study examined the impact of fine and gross motor ability on self-perceptions of male and female children and adolescents. Participants were compared across age group, sex, and level of motor ability. When intercorrelations between self-perceptions were taken into account, the level of movement ability was found to impact upon perceived athletic competence and scholastic competence. When movement was considered in terms of fine and gross motor ability, it was found that those with higher perceived scholastic competence were in the younger group and had better fine motor skills. Furthermore, those with greater perceived athletic competence were also in the younger group, were predominantly male and had better gross motor skills. The types of self-perceptions that influenced self-worth were dependent on the level of motor ability of the participants and varied according to their sex. The implications of these findings are discussed with reference to the necessity to assess specific types of motor deficit when tailoring intervention strategies for children with motor disorders, particularly within the academic setting.     

Domain Compensation in Quality of Life of Individuals with Vasovagal Syncope: a Test of Homeostasis Theory

Although health-related quality of life is often diminished in populations characterised by physical illness, this does not necessarily imply lower overall assessments of general life satisfaction (GLS) and greater incidence of mental illness. According to Homeostasis Theory, this limited impact of health on these more global wellbeing indices may be due to internal and external buffers that serve to maintain one’s overall sense of wellbeing and GLS in the face of adversity. Thus, the present study tested in a sample of 212 individuals (48 with vasovagal syncope, 62 cardiac patients, and 102 healthy control participants) the possibility that poor health-related quality of life (as expected for the cardiac and vasovagal syncope groups) may be offset by relatively higher satisfaction with other aspects of one’s life (the domain compensation hypothesis). Consistent with this view, present findings showed that although individuals in the two health-risk groups reported lower health satisfaction (HSat) than the control group, they had comparable levels of mental health, GLS satisfaction, and subjective wellbeing (minus health; PWI-H). Moreover, moderation analyses confirmed that the relationship between HSat and GLS reduced to non-significance for individuals with PWI-H higher than nationally representative, normative levels. Collectively, these findings suggest that a broader context is necessary to understand the impact that illness may have on one’s sense of GLS and mental health. In particular, the provision of support and satisfaction with other life domains may serve to buffer concerns about one’s health.     

个人自立与自我图式、他人图式

Fitness, attitude toward physical education, and self-concept of elementary school children

Elementary school children scoring in the highest and lowest 26% or 27% of their classes on the Texas Physical Fitness test were compared for attitude toward physical education and self-concept. Data were collected on the Children's Attitude Inventory Toward Physical Education, a Game of Pairs for Preferences Among School Subjects, and the Children's Self-concept Scale. Analysis of variance indicated significant differences on all tests between boys high in fitness, girls high in fitness, boys low in fitness, and girls low in fitness. Subsequent Scheffé tests indicated that highly fit girls had significantly higher attitude and self-concept scores than boys low in fitness. Highly fit boys had higher self-concepts than boys low in fitness. No other group comparisons were significant. Pearson correlations indicated nonsignificant associations between fitness and attitude and self-concept for the four groups.     

Coping with peer stressors and associated dysphoria: Acculturation differences among Chinese-American children

The purpose of this study was to explore the role of acculturation in coping with stress among 264 Chinese-American children. The results confirmed that the subjects used a variety of coping strategies including diversion, suppression, problem solving, minimization, and retaliation and that certain coping strategies influenced the dysphoria experienced as a result of peer stress. High acculturated children used retaliation significantly more often than their low acculturated counterparts and retaliation was found to be associated with less dysphoria for the high acculturated group. In contrast, low acculturated children who utilized suppression tended to report less dysphoria. Contrary to the hypothesis that general self worth would reduce the relationship between peer stressors and dysphoria, it had no bearing on the association for either acculturated group. The hypothesis that greater perceived social competence would lessen the association between peer stressors and dysphoria also failed to be supported by the data. In fact, for the high acculturation group higher social competence was actually associated with more reported dysphoria. In general, the results suggested that the adaptiveness of particular coping strategies may be influenced by acculturation level and that social competence plays a complicated role in the stress and coping process. Implications for counsellors are discussed.     

Children of Mentally Ill Parents Participating in Preventive Support Groups: Parental Diagnoses and Child Risk

In the Netherlands, preventive support groups are offered to children of mentally ill parents. Given the variety of parental diagnoses it might be questionable if offering a standardized program for all these children is the most effective response. While no overall knowledge exists about the type of parental disorder and varying risk levels and support needs among the participating children, we examined whether there are differences between these children that are related to their parents’ diagnoses. With questionnaires we assessed risk factors in 122 mentally ill parents and their children: high parental illness severity, low perceived parental competence, parent–child interaction problems, poor family functioning, difficult child temperament, and low child competence. We also assessed the children’s psychosocial problems and negative cognitions about their parent’s illness. Results showed that most parents had co-morbidity (multiple diagnoses) and/or personality disorders. Children of parents with either of these conditions were more likely to be exposed to the risk factors: high parental illness severity, low perceived parental competence, problematic parent–child interaction, and low perceived child competence, compared to children of parents without these conditions. They were also faced with more risk factors and had more psychosocial problems and negative cognitions. From these results we may conclude that children of parents with co-morbidity and/or personality disorders require more extensive support than children of parents without these conditions. We suggest strengthening the children’s competence and involving parents as important focuses of preventive interventions for children at high risk. Longitudinal studies should test these assumptions.     

Does level of motor competence affect the associations between identity health and self-perceptions in adolescents?

BackgroundAdolescence is a particularly important time for the development of self-perceptions and identity as many environmental and personal factors are influential. One relatively unexplored factor is level of motor competence.AimTo examine the relationship between identity health and self-perceptions in male and female adolescents with low motor competence (LMC) compared to typically developing (TD) adolescents.MethodAdolescents (N = 160, 64.4% males, M_age = 14.45 yrs., SD = 0.75) completed the Adolescent Motor Competence Questionnaire (AMCQ), Assessment of Identity Development in Adolescence (AIDA), and Harter's Self-Perception Profile for Adolescents (SPPA). Based on the AMCQ score, the sample was grouped into LMC and TD. Pearson's product moment correlations between the AIDA and SPPA subscales were derived for gender, competence groups, and gender x competence sub-groups.ResultsOverall, males had lower AIDA scores (healthier identity) than the females and significant associations with all self-perception domains. For females, only scholastic and social competence, physical appearance, behavioural conduct, close friendship and Global Self-worth (GSW) domains were significantly related to their AIDA score. The adolescents in the LMC group had higher AIDA scores (less-healthier identity) and fewer self-perception domains [scholastic competence, physical appearance, behavioural conduct, close friendships and GSW] were associated to their AIDA scores. For the TD group, all self-perception domains were significantly correlated with their AIDA scores. When grouped by gender and motor competence, the TD males had the healthiest identity scores which were strongly associated with all self-perception subdomains. For males with LMC, only scholastic competence, behavioural conduct and GSW domains were significantly related with their identity score. Females from both competence groups reported significant associations between physical appearance, close friendships, behavioural conduct, and social competence domains with their identity scores. Scholastic competence was also significantly associated with identity only for females with LMC.ConclusionPositive self-perceptions across a range of domains are associated with a healthier identity, but differ according to level of motor competence and gender. For those with LMC, the self-perception subdomains unrelated to physical activity and sport, such as school-based aspects were associated with a healthier identity. These findings should guide school based interventions to provide support in these domains in order to strengthen self-worth and identity health.     

儿童2岁活跃性、自我控制与5年后学校适应——父母养育方式的调节作用

通过5年的追踪,考察儿童早期气质特征对后期社会适应的影响。选取200名2岁儿童,采用实验室观察法评价其气质上的活跃性和自我控制;在其7岁时追踪到125名儿童,请父母报告养育方式、班主任老师评价其社会能力和学业表现。结果表明：（1）儿童2岁时的活跃性对5年后学校适应的预测总体是消极的,并且受父母养育方式调节;父母的高限制和低压制能够抵消活跃性对学习问题和任务定向的消极影响;（2）儿童2岁时的自我控制对于5年后的所有积极学校适应指标（学业成绩、低学习问题、果敢社交、挫折耐受、任务定向）有直接预测作用。这一结果揭示了气质上的活跃性与自我控制在儿童发展过程中的不同作用,父母应根据孩子的气质特点实行差别化教育。     

Teachers'' ratings of social competence of children with high versus low levels of depressive symptoms

This study examined the relationship between children's self-ratings of depressive symptoms on the Children's Depression Inventory (CDI) and teachers' ratings of the situational social competence of these children based on the Taxonomy of Problematic Social Situations (TOPS). Children in the high CDI group showed significantly higher teacher ratings (indicating lower social competence) than children in the low CDI group on four TOPS scales: peer group entry, response to provocation, response to success, and teacher expectations. Of the children in the high CDI group, 85% could be correctly classified with a discriminant analysis on the basis of TOPS ratings; of the children in the low CDI group, 77% were correctly classified. Implications of these findings, as well as limitations of the study, are discussed.     

Risk and Protective Factors for Children of Adolescents: Maternal Depression and Parental Sense of Competence

We investigated the relationship between depression and parental sense of competence to child cognitive outcomes for a sample of 49 adolescent mothers and their young children (Mean age=9 1/2 months) enrolled in a student parenting program. Cognitive development of the infants and toddlers was assessed using the Bayley Scales of Infant Development. Maternal depression was assessed with the CES-D and parental competence measured with the Parental Sense of Competence Scale. Results indicated that maternal depression and parental sense of competence alone did not predict children’s cognitive scores; the interaction of the variables significantly predicted children’s outcomes. Mothers reporting high levels of depression, who self-reported high levels of parental competence, had children who scored higher on the Bayley. Children of mothers with high levels of depression, and low reported levels of competence scored lower on the Bayley. The relationship was not significant for mothers reporting low levels of depression. Our findings suggest additional research needs to focus on the buffering effect of parental sense of competence for adolescent mothers experiencing depression.     

Judging the differences between women's attractiveness and health: Is there really a difference between judgments made by men and women?

Perceived weight in the face and body size have been shown to be significant predictors of both attractiveness and health. Studies looking at the relationship between attractiveness, perceived health, and perceived weight in faces have found that individuals prefer a lower weight for attractiveness than for apparent health. Here, a group of twenty-four Asian participants were allowed to manipulate the apparent body mass indices (BMIs) of full-length photographs of young Malaysian Chinese women to enhance their perceived healthiness and attractiveness. Results showed that both men and women differentiated between attractiveness and health by preferring a lower BMI for attractiveness than health, suggesting a consistency in the preferred ideal BMI for attractiveness and healthy appearance across both sexes. Results also suggested that BMI provides important cues to judgments of attractive and healthy appearance.     

Extracorporeal Membrane Oxygenation versus Conventional Treatment: Neurodevelopmental and Social Outcomes at 24 Months

The purpose of this prospective, controlled study was to compare neurodevelopmental and social outcomes at 2 years of age for children treated with extracorporeal membrane oxygenation (ECMO; n = 25) to those of children with severe respiratory illness treated with conventional methods (CT; n = 16) and to matched, healthy full-term (FT; n = 29) children. Mothers' parenting attitudes and children's mental, motor, language, exploratory play, and social competence skills were assessed. A retrospective chart review was also undertaken to further describe the groups with respect to the results of neuroimaging, audiologic, and neuromotor examinations. The FT group had significantly higher mental, motor, and language scores as compared to the ECMO and CT groups. Groups did not differ on measures of behavior, social competence, exploratory play skills, or parental attitudes. Specifically for the ECMO group, there was a trend toward language being more problematic than other areas of development. In general, the data demonstrate that severe respiratory complications, regardless of type of treatment, place children at increased risk for neurodevelopmental difficulties.
