Bryant's Empathy Index: Structure and Measurement Invariance across Gender in a Sample of Primary School-Aged Children.
2016
AbstractThe purpose of this study was to examine the dimensional structure and measurement invariance of Bryant’s Index of Empathy for Children and Adolescents (IECA) (Bryant, 1982) across gender in a representative sample of primary school-aged children in Spain. The sample consisted of 2,050 children (50.80% girls), with a mean age of 9.80 years (SD = 1.24), recruited from 27 primary schools. Exploratory and confirmatory factor analyses were conducted. The model that presented the best fit indices was Lasa, Holgado, Carrasco, and del Barrio’s (2008) three-factor model: Understanding Feelings, Feelings of Sadness, and Tearful Reaction. The levels of internal consistency for the subscales r…
Sport burnout inventory–Dual career form for student-athletes: Assessing validity and reliability in a Finnish sample of adolescent athletes
2020
Background: The pressure of pursuing an athletic career simultaneously with education may set adolescent student-athletes at risk for sport and school burnout. Although the 2 life domains of student-athletes are strongly intertwined, so far, there has not been an instrument for investigating sport burnout parallel to school burnout. The aim of the present study was to introduce a sport burnout measure for adolescents in a dual career context and investigate its validity and reliability by using confirmatory factor analysis. Methods: The participants were 391 student-athletes (51% females) who filled in a questionnaire of sport burnout and background variables in the beginning of upper secon…
Retrospective study of maxilla growth in a Spanish population sample
2010
This study has been designed to evaluate the vertical and sagittal changes in the maxilla due to growth. A sample group was chosen of 38 individuals with normal occlusion, composed of 16 females and 22 males between the ages of 8 and 18. The total sample was divided into three groups: prepubescent (8-11 years), pubescent (12-14 years) and post-pubescent (15-18 years). A series of cephalometric angle parameters (SNA, maxillary height, slope of the palatal plane and maxillary depth) and lineal parameters (effective maxillary length, palatal plane length, middle third of the face height and convexity) were traced. Superimpositions of the initial and final cephalometries in the Ba-N plane and i…
Prevalence of cytomegalovirus infection in Italy
1991
SUMMARYBetween 1987 and 1989, the prevalence of antibody to cytomegalovirus (CMV) was determined, by the ELISA method, in serum samples from 1494 apparently healthy subjects, 3–18 years old. Subjects were selected by a systematic cluster sampling from five geographical areas in Italy. The overall prevalence of antibody was 64·2%, increasing from 54·4% in 4–6-year-olds to 73·3% in subjects 17–18 years old (P < 0·01). Prevalence of antibody was significantly higher in females (P < 0·05) and in subjects residing in the South of Italy (P < 0·01). A significant association was found with sociodemographic factors. Subjects belonging to a household with six or more persons had a 1·5-fold …
The Father in Youth Baseball: A Self-Determination Theory Approach
2021
This study based on the self-determination theory aims to examine the relationship among the aspirations that fathers have about their children’s youth baseball practice, the children’s basic psychological needs (satisfaction and frustration), and their intentions to either continue or drop out of baseball practice in a sample of children from Hermosillo, Mexico. A cross-sectional study was carried out involving 533 fathers (M = 44.30, SD = 5.18) and 533 children (M = 13.09, SD = 1.68). The results showed that the intrinsic aspirations of fathers were positively correlated to the satisfaction of the children’s psychological needs, whereas the extrinsic aspirations of fathers were positively…
Is It Possible to Measure the Role of the Bystander and the Victim of Bullying in Children? Construct Validity of Two Brief Pictorial Scales With IRT…
2021
The study's objective was to develop and validate the psychometric properties of two brief pictorial scales to evaluate the roles of bystanders and victims of bullying. A sample of 910 students was considered (49.6%, boys; 50.4%, girls) between the ages of 7 and 13 (M = 10, SD = 1.4). Both instruments present nine pictorial items representing two dimensions: physical bullying (items 1 to 4) and psychological bullying (items 5 to 9). An additional measure of anxiety was used to assess convergent validity. The Confirmatory Factorial Analysis shows that the two-dimensional oblique model, physical bullying and psychological bullying, presents a better fit to the bystander scale data (RMSEA = .…
Children's eating attitudes test: Validation in a sample of Spanish schoolchildren
2010
Objective: To validate the Spanish version of the Children's Eating Attitudes Test (ChEAT). Method: The factor structure and other psychometric characteristics of the questionnaire were examined using the answers of 38,554 schoolchildren. Diagnostic efficiency was based on a standardized clinical interview of 968 schoolchildren who had previously completed the questionnaire. Results: Five factors (“preoccupation with thinness,” “dieting,” “social pressure to eat,” “purging,” and “preoccupation with food and oral control”) explained 46% of the variance. Cronbach's α was .858 for the total scale. The area under the receiver operating characteristic curve was .851. Sensitivity (SE) was 27% and…
The Prevalence of sexual abuse in institutions : Results from a representative population-based sample in Germany
2018
The lifetime prevalence of sexual abuse in institutional settings in Germany was examined in a sample representative of the general adult population (N = 2,437). Participants completed a survey on whether they had ever experienced such abuse, its nature (contact, noncontact, forced sexual, intercourse), the type of institution (e.g. school, club), and the relationship of perpetrator to victim (peer, caregiver, staff member). Overall, 3.1% of adult respondents (women: 4.8%, men: 0.8%) reported having experienced some type of sexual abuse in institutions. Adult women reported higher rates of all types than did men, with rates of 3.9% versus 0.8% for contact sexual abuse, 1.2% versus 0.3% for …
Obstacles to intergroup contact: When outgroup partner's anxiety meets perceived ethnic discrimination
2013
Emerging research suggests that outgroup partner's anxiety can disrupt intergroup rapport-building. This study extends previous findings by investigating the interactive effects of anticipated outgroup partner's anxiety and perceived ethnic discrimination on self-anxiety and intergroup contact avoidance. A sample of immigrant adolescents belonging to different ethnic minorities in Italy (N = 118) was considered. Results showed that when participants expected to interact with an anxious outgroup (Italian) versus in-group partner, self-anxiety increased and, as a consequence, their intentions to avoid future encounters. However, these effects were observed only for participants with higher (v…
Genetic and environmental influences on psychological traits and eating attitudes in a sample of Spanish schoolchildren.
2014
Introduction: The heritability of eating disorders has been estimated to range from 22% to over 62%.The aim of this study is to determine the relative influence of genetics and environment that contribute to the drive for thinness, body dissatisfaction, perfectionism, and ineffectiveness, by evaluating sex differences in a sample of adolescent twins from Valencia, Spain. Material and methods: Five hundred eighty-four pairs of adolescent twins between 13 and 18 years of age completed the study. To determine zygosity, teachers responded to a questionnaire on physical similarity. Psychological traits of eating disorders were assessed with four sub-scales of the Eating Disorder Inventory (EDI);…
