Associations of Masticatory Muscles Asymmetry and Oral Health with Postural Control and Leg Injuries of Elite Junior Soccer Players.

The influence of asymmetry between masticatory muscles on postural control is still under debate and only few studies examined the impact of oral health on injury risk. The present study investigated the relationships between masticatory muscles asymmetry, oral health, postural control and the prevalence of (non-contact or traumatic) leg injuries in a sample of 144 male elite junior soccer players. sEMG of the masseter and temporal muscles was performed during maximum teeth clenching, postural control was tested by measuring sway velocity during the unipedal stance with eyes closed, while oral health and the number of leg injuries were assessed using a questionnaire.

Are oral health and fixed orthodontic appliances associated with sports injuries and postural stability in elite junior male soccer players?

Background: Dental caries and periodontitis are associated with elevated levels of pro-inflammatory cytokines which may trigger muscle fatigue during exercise, a strong risk factor for sports injuries. Fixed orthodontic appliances (FOA) may cause poor oral health and may disturb proprioceptive inputs of the stomatognathic system. This study aims to explore associations of poor oral health and of use of a FOA with injury frequency and postural stability.

Associations between poor oral health and reinjuries in male elite soccer players: a cross-sectional self-report study.

Background: Although it is well known that oral pathogens can enter the systemic circulation and cause disease, it is largely unknown if poor oral health increases the risk of sports injuries. The purpose of this study is to investigate the association between poor oral health and reinjuries in male elite soccer players, adjusted for psychosocial problems and player characteristics.

Methods: 184 Players in premier league soccer clubs and 31 elite, junior soccer players in the Netherlands, Belgium and England, were enrolled in a retrospective cross-sectional study.

Characteristics of children and adolescents in the Dutch national in- and outpatient mental health service for deaf and hard of hearing youth over a period of 15 years.

In this study socio-demographic, deafness-related and diagnostic characteristics of hearing impaired children and adolescents referred to a national mental health service for deaf and hard of hearing children and adolescents were examined. Socio-demographic and diagnostic characteristics were compared to corresponding characteristics of hearing referred peers with identified mental health problems. The difference in characteristics between them and hearing referred peers with identified mental health problems was analyzed.

Self-concept and ego development in deaf adolescents: a comparative study.

Self-concept and ego development, two intertwined aspects of self-indicating well-being and social-cognitive maturation, respectively, were examined in a representative sample of deaf adolescents of normal intelligence (N = 68), using translated and adapted versions of Harter's (1988, Manual for the self-perception profile for adolescents. Denver, CO: University of Denver) multidimensional measure of self-concept and Loevinger's (1998, Technical foundations for measuring ego development. Mahwah, NJ: Lawrence Erlbaum) measure of ego development.

Confirmatory factor analysis and factorial invariance analysis of the adolescent self-report Strengths and Difficulties Questionnaire: how important are method effects and minor factors?

OBJECTIVES. This study examined the factor structure of the self-report Strengths and Difficulties Questionnaire, paying special attention to the number of factors and to negative effects of reverse-worded items and minor factors within the subscales on model fit. Furthermore, factorial invariance across gender, age, level of education, and ethnicity was investigated.

Self-concept and psychopathology in deaf adolescents: preliminary support for moderating effects of deafness-related characteristics and peer problems.

Background: High rates of psychopathology were found amongst deaf adolescents, but little is known about the psychosocial risk factors. This study investigated whether (1) less severe deafness and/or acquired or otherwise complicated deafness, and (2) having mainly contacts with hearing people, each represent chronic stressful conditions that moderate the associations between self-esteem and emotional problems. In addition, the moderating effect of observed peer rejection on the association between social acceptance and behavioural problems was explored.

Examining the relation between the therapeutic alliance, treatment adherence, and outcome of cognitive behavioral therapy for children with anxiety disorders.

Little is known about the contribution of technical and relational factors to child outcomes in cognitive behavioral therapy (CBT) for children with anxiety disorders. This study investigated the association between treatment adherence, the child-therapist alliance, and child clinical outcomes in manual-guided individual- and group-based CBT for youths diagnosed with anxiety disorders. Trained observers rated tapes of therapy sessions for treatment adherence and child-therapist alliance in a sample of 52 children (aged 8 to 12) with anxiety disorders.

The relation of severity and comorbidity to treatment outcome with Cognitive Behavioral Therapy for childhood anxiety disorders.

The present study investigated the impact of comorbidity over and above the impact of symptom severity on treatment outcome of Cognitive Behavioral Therapy for children with anxiety disorders. Children (aged 8-12, n = 124) diagnosed with an anxiety disorder were treated with a short-term CBT protocol. Severity was assessed with a composite measure of parent-reported behavior problems.

A survey of self-directed dying attended by proxies in the Dutch population.

Physicians may hasten death by medical decisions to end life (MDEL) that have been extensively researched. However, outside the medical domain, some individuals hasten their death by Voluntary Refusal of Food and Fluid while receiving some palliative care (VRFF) or by Independently taking Lethal Medication attended by a Confidant (ILMC). Both dying trajectories are more or less under the control of the individuals themselves.

Parenting and parental anxiety and depression as predictors of treatment outcome for childhood anxiety disorders: has the role of fathers been underestimated?

A substantial percentage of children with anxiety disorders do not respond adequately to Cognitive Behavioral Therapy (CBT). Examination of parental factors related to treatment outcome could contribute to a further understanding of treatment outcome responses. This study investigated the predictive value of paternal and maternal emotional warmth, rejection, overprotection, anxiety, and depression for CBT outcome in clinic-referred anxious children (ages 8-12).

Prevalence and correlates of psychopathology in a sample of deaf adolescents.

Aims: To examine prevalence and correlates of psychopathology in deaf adolescents using a multi-method multi-informant approach.

Methods: Data for the study came from checklist assessments by parents (Child Behavior Checklist (CBCL)) and teachers (Teacher's Report Form (TRF)) of 70 deaf adolescents aged 13 to 21 years, from semi-structured clinical interviews of the adolescents (Semi-structured Clinical Interview for Children and Adolescents (SCICA)), and from expert ratings of dossier data.

Results: The percentages of Total Problems scores in the borderline clinical range in this population as found with the CBCL, TRF and SCICA are 28%, 32% and 49-63% respectively.

A developmental analysis of self-reported fears in late childhood through mid-adolescence: social-evaluative fears on the rise?

Background: The frequently reported decline in the overall frequency and intensity of fears during late childhood and adolescence may mask different developmental patterns for two broad subclasses of fears: fears concerning physical danger and fears concerning social evaluation. It was investigated if physical fears decrease between late childhood and mid-adolescence, while social-evaluative fears increase during this period. It was also studied if changes in both sets of fears are more strongly related to socio-cognitive maturity than to age, which itself is only a proxy measure of maturity.

Dutch version of the Strengths and Difficulties Questionnaire (SDQ).

A Dutch translation of the Strengths and Difficulties Questionnaire (SDQ) was made. In the first wave of data collection, self-report data of 11- to 16-yearolds (N = 970) were collected on the SDQ and other measures of psychopathology. In the second wave of data collection, extended versions of the SDQ were completed by 11- to 16-year-olds (N = 268), by parents of 8- to 16-year-olds (N = 300) and by teachers of 8- to 12-year-olds (N = 208); in addition, the Child Behaviour Checklist (CBCL) was completed by the parents and the Youth Self Report (YSR) by the 11- to 16-year-olds.

The facets of anxiety sensitivity represented in the childhood anxiety sensitivity index: confirmatory analyses of factor models from past studies.

Results of past factor analytic studies of the Childhood Anxiety Sensitivity Index and Anxiety Sensitivity Index were used to formulate hypotheses about factor models of anxiety sensitivity. Using a nonclinical sample of 767 children and adolescents and confirmatory factor analysis, hypothesized models with 2, 3, and 4 lower order factors (facets) were tested. Goodness-of-fit criteria indicated that a model with 4 facets fits these data well.

Negative symptoms in Alzheimer's disease: a confirmatory factor analysis.

Objective: To examine different conceptual models of negative symptoms in Alzheimer's disease.

Design: Confirmatory factor analysis of cross-sectional data.

Subjects: Alzheimer patients (n=281) admitted to a psychogeriatric observation ward.

The Dutch Childhood Anxiety Sensitivity Index: psychometric properties and factor structure.

Examined the reliability, validity, and factor structure of the Childhood Anxiety Sensitivity Index (CASI; Silverman, Fleisig, Rabian, & Peterson, 1991) in a Dutch sample. Five hundred forty-four Dutch schoolchildren between 8 and 16 years of age completed Dutch translations of the CASI; the State-Trait Anxiety Inventory for Children (Spielberger, Edwards, Lushene, Montuori, & Platzek, 1973); and the Fear Survey Schedule for Children-Revised (Ollendick, 1983). The Dutch CASI was found to have adequate internal consistency for use with children as well as adolescents.
