“…It is known that among children, Reward Dependence, Persistence, Cooperativeness, and Self-directedness are positively related to intelligence and academic achievement [44], [45], which would suggest that twins might have better prerequisites for performing well in school and in academic life. However, other studies have found that twins have substantially lower IQs [46] and perform less well academically later in life [47] than singletons.…”

“…The Congruent Second Nature vs. Bad Habits Self-directedness facet of the TCI, for instance, can actually measure self-discipline. Among adolescents, self-discipline outdoes IQ when predicting academic performance [56], [45]. In light of the studies showing lower IQ among twins compared to singletons [47], studies showing equal or even slightly better academic performance among twins compared to singletons [48], [49], and the results presented here showing higher Self-directedness scores among twins compared to general population groups, it is reasonable to suggest tentatively that twins might overcome having lower IQs as long as they develop a spectrum of goal-congruent, good habits so that they automatically act in accordance with their long-term values and goals, as high scorers in the Congruent Second Nature vs. Bad Habits Self-directedness facet are defined.…”

BackgroundThe Child and Adolescent Twin Study in Sweden (CATSS) is an on-going, large population-based longitudinal twin study. We aimed (1) to investigate the reliability of two different versions (125-items and 238-items) of Cloninger's Temperament and Character Inventory (TCI) used in the CATSS and the validity of extracting the short version from the long version, (2) to compare these personality dimensions between twins and adolescents from the general population, and (3) to investigate the genetic structure of Cloninger's model.MethodReliability and correlation analyses were conducted for both TCI versions, 2,714 CATSS-twins were compared to 631 adolescents from the general population, and the genetic structure was investigated through univariate genetic analyses, using a model-fitting approach with structural equation-modeling techniques based on same-sex twin pairs from the CATSS (423 monozygotic and 408 dizygotic pairs).ResultsThe TCI scores from the short and long versions showed comparable reliability coefficients and were strongly correlated. Twins scored about half a standard deviation higher in the character scales. Three of the four temperament dimensions (Novelty Seeking, Harm Avoidance, and Persistence) had strong genetic and non-shared environmental effects, while Reward Dependence and the three character dimensions had moderate genetic effects, and both shared and non-shared environmental effects.ConclusionsTwins showed higher scores in character dimensions compared to adolescents from the general population. At least among adolescents there is a shared environmental influence for all of the character dimensions, but only for one of the temperament dimensions (i.e., Reward Dependence). This specific finding regarding the existence of shared environmental factors behind the character dimensions in adolescence, together with earlier findings showing a small shared environmental effects on character among young adults and no shared environmental effects on character among adults, suggest that there is a shift in type of environmental influence from adolescence to adulthood regarding character.

“…Essa variação pode ser explicada à luz das mudanças desenvolvimentais dos alunos, isto é, crianças/jovens mais novos tendem a ser mais otimistas em relação às suas competências (Nicholls & Miller, 1984) do que crianças/jovens mais velhos, que tendem a ter uma visão mais crítica acerca das suas capacidades (Fredericks & Eccles, 2002). Além disso, dimensões disposicionais e relativamente estáveis ao longo do tempo, como a personalidade, exercem uma influência significativa em múltiplos resultados acadêmicos, incluindo o desempenho escolar e o envolvimento com a escola (Moreira et al, 2012d).…”

Estudos de Psicologia I Campinas I 32(2) I 187-199 I abril -junho 2015 ResumoAs associações entre as percepções dos alunos acerca das características da escola e o envolvimento dos alunos com a escola são ainda pouco compreendidas. O objetivo deste estudo foi avaliar a relação entre a percepção dos alunos acerca das estratégias de promoção de sucesso educativo e o seu envolvimento com a escola. Participaram neste estudo 529 alunos do 2º e 3º ciclo de um município do Norte de Portugal, Vila Nova de Famalicão. Os resultados demonstram a existência de uma correlação positiva e estatisticamente significativa entre a percepção dos alunos acerca das estratégias de otimização de aprendizagem e o envolvimento escolar. Estes resultados têm fortes implicações para os esforços de melhoria e da eficácia da escola, incluindo para a promoção de trajetórias acadêmicas positivas. Palavras-chave:Educação; Percepção; Realização; Rendimento escolar. AbstractThe association between the students' perception of the school characteristics and the students' engagement with school requires further research.

“…However, the sample size was not large enough to conduct detailed analyzes of psychometric properties. Junior versions of the TCI for children and adolescents are as yet less widely employed [7][8][9][10][11][12][13][14][15][16][17]. Out of these studies, using a representative Korean sample (663 middle-school students, 360 males and 303 females), Lyoo et al [13] examined the reliability and validity of Junior version of the TCI, with Cronbach's alpha values ranging from 0.48 to 0.80 for the temperament and from 0.64 to 0.68 for the character scales.…”

Objective: Junior Temperament and Character Inventory (J-TCI) was developed by Luby, Svrakic, McCallum, Przybeck, and Cloninger based on Cloninger's biopsychosocial model to assess temperament and character dimensions in children and adolescents. Methods: The Turkish version of J-TCI-Revised (J-TCI-R) was administered to 1129 elementary and middle-school (male/female, 546/583) students. Internal consistency reliabilities were measured by Cronbach's alpha; test-retest was assessed across one month. Results: Cronbach's alphas for the subscales of J-TCI-R ranged from 0.60 to 0.75 for temperament and character subscales, which were comparable to US and other populations. The correlations between baseline and one month after administration of J-TCI-R were highly and statistically significant (r = 0.578-0.674 for scales and 0.366-0.582 for subscales) (n = 795). Factor analysis results using Eigenvalue greater than one rule indicated three out of four factors for temperament scales and one out of two factors for character subscales which were similar to findings from the other countries. When all of the subscales were subjected to factor analysis, four out of six factors were retained. To our knowledge, this is the first study analysing psychometric properties and factorial construct of the J-TCI-R. Conclusions: The internal reliability coefficients and test-retest indicated a good stability of scores over time and the factorial structure was consistent with Cloninger's model of personality. The reliability and validity of the Turkish version of the TCI is therefore supported. ARTICLE HISTORY
