    The effect of psychological state and social support on nail-biting in adolescents: An exploratory study
    (SAGE PUBLICATIONS LTD, 2017) ERGÜN, AYŞE; Sisman, Fatma Nevin; Tok, Ozlem; Ergun, Ayse
    Nail-biting is one of the most common behavioral problems in children. This study aimed to examine factors affecting nail-biting among adolescents and the effects of psychological state and social support on nail-biting. This cross-sectional study was conducted between January and May of 2014 in seven schools in Istanbul (N=724). Data were collected using the Personal Information Form, Brief Symptom Inventory, and Child and Adolescent Social Support Scale. This study found that 48.2% of adolescents in the 11- to 17-years-old age group had a habit of nail-biting. Anxiety, depression, negative self image, somatization, hostility, and three global index scores of adolescents who bit their nails were significantly higher than in those who did not. Social support scores of those who bit their nails were significantly lower than in those who did not in the mother' and classmates' subscales and total scores. Psychological state and social support were factors affecting nail-biting among adolescents.

    Psychometric properties of the Turkish version of the behavior assessment for children (BAC) scale
    (SPRINGER, 2021-11) SEZER BALCI, AYŞE; Sisman, Fatma Nevin; Ergun, Ayse; Sezer Balci, Ayse
    Behavioral problems are seen in one out of four school-age children. There are difficulties in evaluating children's behavior in Turkish culture and therefore a valid and reliable measuring tool is needed for assessing behavioral problems in this age group. The aim of this study was to evaluate the psychometric properties of the Turkish version of the Behavior Assessment for Children (BAC). The study was conducted using the cross-sectional data collection method to examine the content validity, factor structure, measurement invariance, reliability of BAC based on data from 495 parents and 14 teachers. The Content Validity Index (CVI) was used for testing content validity. Reliability analysis was carried out with Cronbach's alpha, MacDonald's omega test, item total correlations, Spearman Brown's and Guttman's split-half reliability coefficients, percent agreement and intraclass correlation coefficients (ICC). Construct validity was evaluated by confirmatory factor analysis (CFA). The measurement invariance was examined by multiple-group CFA. The CVI of the BAC was found to be .92. Three models were tested with CFA, and a 17-item, three-factor (attention, emotion, self-control) structure of the BAC was finally supported; this dimensional structure proved to be invariant across gender. Factor loadings varied between .56 and .83. Cronbach's alpha was .93; ICC was .60. Percent agreement varied between 41.6%-63.1%. It was determined that the BAC scale is a valid and reliable instrument that can be used to assess the behavioral problems of Turkish children. Its results can moreover contribute to the cross-cultural study of behavior problems and add to worldwide discussions.
