This 1-year follow-up study was performed to examine the association of temperament and character dimensions with new onset of fatigue-induced symptoms among school children in Japan, focusing on the transition from childhood to early adolescence.
This study prospectively reviewed data from 1512 school children from four elementary and four junior high schools in Japan. The survey was conducted in 2006 and 2007. Multivariate logistic regression analyses were performed to examine the association of psychological dimensions, assessed by the Junior Temperament and Character Inventory, with fatigue-induced symptoms.
The correlation between temperament and character dimensions with new-onset of fatigue-induced symptoms differed as the students advanced into higher grades. In terms of physical symptoms in males, traits correlated with fatigue-induced symptoms included Novelty Seeking (headaches OR, 1.36; 95% CI, 1.07-1.73) or Reward Dependence (extreme tiredness OR, 1.84; 95% CI, 1.09-3.12; muscle weakness OR, 2.32; 95% CI, 1.28-4.20) during elementary school, whereas in females, Novelty Seeking was mainly associated with both physical (morning fatigue OR, 1.40; 95% CI, 1.10-1.77; headaches OR, 1.22; 95% CI, 1.04-1.43) and mental (mood changes OR, 1.30; 95% CI, 1.09-1.56) symptoms. Among ninth graders, more mental symptoms of fatigue were associated with Harm Avoidance (males, poor motivation OR, 1.20; 95% CI, 1.02-1.42; females, mood changes OR, 1.25; 95% CI, 1.06-1.49) and Self Directedness (males, poor motivation OR, 0.75; 95% CI, 0.59-0.96; females, difficulty thinking OR, 0.78; 95% CI, 0.62-0.98).
Confirmation that the correlation between personality traits and fatigue-induced symptoms changes with grade at school has implications for screening susceptible children and adolescents and may help prevent the occurrence of such symptoms at an early stage.

"Elevated levels of HA have also been reported among depressed adolescents . Different relationships between temperament and character traits and mental health are suggested to exist in adolescents and adults . Therefore, more research is needed to improve our understanding of the relationship between adolescent depression and personality. "
[Show abstract][Hide abstract] ABSTRACT: Background. Focus upon depression and prevention of its occurrence among adolescents is increasing. Novel ways of dealing with this serious problem have become available especially by means of internet-based prevention and treatment programs of depression and anxiety. The use of Internet-based intervention programs among adolescents has revealed some difficulties in implementation that need to be further elucidated. The aim of this study is to investigate the association between personality and adolescent depression and the characteristics of users of an Internet-based intervention program. Method. The Junior Temperament and Character Inventory (JTCI), the General Self-Efficacy scale (GSE) and the Centre for Epidemiological Studies-Depression scale (CES-D) have been administered to a sample (n = 1234) of Norwegian senior high-school students. Results. Multiple regression analysis revealed associations between depression and gender, and several JTCI domains and facets. In line with previous findings in adults, high Harm Avoidance and low Self-Directedness emerged as the strongest predictors of adolescent depressive symptoms. Further, in logistic regression analysis with the covariates JTCI, GSE and CES-D, the only significant variables predicting use/non-use were the CES-D and the temperament domain Reward Dependence. Conclusion. The results in this study revealed level of depressive symptoms as the strongest predictor of the use of the Internet based intervention and that personality might provide useful information about the users.

[Show abstract][Hide abstract] ABSTRACT: Along the Southeast Atlantic coast of the U.S., attractiveness of climate and an ocean setting higt’llighted by a string of barrier islands and sandy beaches have drawn large numbers of people not only to visit but also to become permanent residents of the coastal zone. This expansion has been part of the increasing demand for outdoor recreation, the national movement toward the coasts, and other economic factors including overall growth in the Southeast. However, weather in any one year may stimulate or curtail recreational activities and, as in the case of destructive hurricanes, interrupt short-term recreational and residential development in a specific locality. This paper analyzes the relationship between climate and long-term recreational development along the Southeast coast. %en, using 1986 as the study year, the paper assesses short-term weather impacts on recreational usage and related development in the Southeast coast zone.
[Show abstract][Hide abstract] ABSTRACT: We examined relationships among fatigue, sleep quality, and effort-reward imbalance for learning in school children. We developed an effort-reward for learning scale in school students and examined its reliability and validity. Self-administered surveys, including the effort reward for leaning scale and fatigue scale, were completed by 1,023 elementary school students (grades 4-6) and 1,361 junior high school students (grades 7-9) at the end of 2006. Effort-reward imbalance for learning was associated with a high incidence of fatigue and sleep problems in elementary and junior high school students of both genders. A good relationship with family was associated with a low fatigue score in junior high school boys, and a good relationship with friends was associated with a low fatigue score in junior high school girls by multiple regression analysis. Fatigue score was associated with effort-reward imbalance and fatigue and quality of sleep in schoolchildren. Fatigue may lead to a decline in school performance, negative health outcomes, or refusal to attend school. These results suggest that it is desirable to consider social support, quality of sleep, and effort-reward imbalance when managing fatigue in school children.
