This study examined the extent to which depletion of mental effort modulated the change in
sustained attention during a prolonged information processing task. Twenty subjects participated
in an 8-hour proofreading task during which mental effort (heart rate variability), sustained
attention (SART), task performance and subjective fatigue were measured. The results showed
significant increases in subjects' mental effort and decreases in task performance later in the task.
There were also significant decreases in sustained attention by the end of the task. Sustained
attention was found to only correlate with subjective fatigue but not mental effort. The
implications of findings are discussed.

This paper will report on the Research with East London Adolescents’ Community Health Survey
(RELACHS) which is a longitudinal, representative, school based study of adolescents’ mental
and physical health. The baseline data surveyed adolescents in Year 7 (11-12yrs) and Year 9
(13-14yrs) and the follow-up data was collected two years later. This paper will report on the
relationships between mental health and past and present health behaviours and physical health.
The paper will discuss whether physical health and health behaviours predict future psychological
distress in adolescence, and identify risk and protective factors for adolescents’ mental health.

Hongmei Tao, Yan Xu, Beijing Normal University, China
Using the Psychological Health Scale of High School Students, the high school students’
psychological health status among 415 migrant students and 230 local students in Beijing was
investigated and a comparison was made between them. The result indicated that 1) migrant
students had slight psychological problems on all dimensions, with obsession, imbalance in
emotion, disadaptation and sensitivity in interpersonal relationship listed the most. 2) the scores of
the 9th grade were significantly higher than other grades on anxiety, study stress and imbalance in
emotion, with no gender difference. 3) migrant students scored significantly higher than local
students on all dimensions.
5132.5 Research on mental health of middle school instructors, Yan Ma, Fu Genyue,

This research was to investigate mental health of middle-school-instructors (N=110) with a
SCL-90 survey. Distinct from previous studies, a special concern was given to class-directors, as
they were more likely to bear stress and take responsibilities. Shown from results, among
junior-school-instructors, the depression rate of class-directors was significantly higher than that
