Adherence-health status relationships in childhood diabetes 总被引:4,自引:0,他引:4
Used 24-hr recall interviews to assess adherence in a sample of seventy-eight 6- to 19-year-olds with insulin-dependent diabetes mellitus over a 3-month period. Thirteen adherence measures were quantified and grouped into six adherence factors (Injection, Exercise, Diet Type, Testing/Eating Frequency, Calories Consumed, and Concentrated Sweets). Prevailing glucose levels over a 2- to 3-month interval were indexed by glycosylated hemoglobin A1c (HA1c) and glycosylated serum protein (GSP) assays. Fasting triglycerides (TRIG) and total cholesterol (CHOL) assays were used to estimate lipid metabolism. Adolescents were generally less adherent than their young counterparts. Using hierarchical multiple-regression techniques, HA1c and GSP were not reliably predicted by most of the adherence factors; only Calories Consumed showed any predictive power. No significant regression equations emerged for CHOL. In contrast, TRIG was significantly associated with five of the six adherence factors; in all cases, adherence interacted with the patients' metabolic status (as defined by HA1c) at study entry, suggesting that adherence had different effects for youngsters in good versus poor diabetes control. 相似文献

A computer program was written in PCPilot to teach a unit in basic concepts in experimental design. The graphics-based program includes both tutorials and simulations. The students who used the program had significantly higher test scores than those in another class who did not; they reported that they enjoyed learning to use the program. 相似文献

This research tested the hypothesis that the "freshman 15" may be more fantasy than fact. The "freshman 15" refers to the belief that college students, particularly women, gain an average of 15 pounds during their first year of college. Female college students were weighed during their first month at college and again 6 months later. They also completed measures of self-esteem, body image, locus of control, and self-monitoring. Findings indicated that the majority of women remained the same weight during the first 6 months of college. A favorable body image was related to less weight loss among those who lost weight, but none of the other characteristics were related to weight change. 相似文献

The convergent validity of the two most frequently used methods for assessing violent offending in juveniles (i.e., selfreports and arrests) was evaluated. Participants were 87 serious juvenile offenders and their maternal figures, primarily from disadvantaged families. Validation measures tapped established behavioral, family, and peer correlates of delinquency. Results failed to support the ability of either arrests for violent crimes or selfreported violent offenses to index violent criminal behavior accurately. Several methodological features of the study support our hypothesis that the findings were not spurious. Procedural and conceptual implications of the findings are discussed.The Family and Neighborhood Services Project was funded by Grant 2H87MH43557-04 to the South Carolina Department of Mental Health from the National Institute of Mental Health.

This paper presents the results of a study testing components of the Triandis model of choice to predict intention to obtain screening mammography in the next 2 years. A questionnaire was developed to measure the theoretical components of this model. Analysis was based on 2,521 women, 50 to 65 years old, who received primary care from 1 of 28 participating primary care group practices. Based on the four theoretical components of intention described in the Triandis model-social influence, affect, consequence, and barriers-a set of structural equation models was explored. The sample was split into two equal subsamples: one sample used for model exploration and one used for model confirmation. Results showed that the original intention model was not supported. Instead, the model that best fit the data, and upheld it in the subsample used for model confirmation, was a model in which habit and intention were strongly related. The strongest predictors of habit were barriers and consequences; the strongest predictors of intention were social influences and barriers. 相似文献

College courses are generally developed because of current fashion in the field and/or student and faculty interest in some topic without reference to departmental or programmatic goals. Current calls and needs for accountability in higher education demand a more organized approach. A computer program, ToolBook 1.53, which provides information to the instructor about systematic development of courses and assessment of student outcomes, is described. The program supports the construction of outcome-oriented learning objectives and corresponding assessment techniques. Instructors who used this program to learn about how to construct such objectives showed an increase in knowledge and evaluated the program positively. Using the information provided in this program leads to an integrated approach to course design and development in which course objectives are linked to the college mission statement through departmental or program objectives. 相似文献

The optimal stimulation theory proposes that hyperactive children are less tolerant of lower levels of arousal than nonhyperactive children and should thus derive greater gains from stimulation added to repetitive copying tasks than do comparisons. To test this hypothesis, 16 adolescents, rating high on attention and behavior problems, were matched on the basis of age and poor handwriting performance to 16 controls. Matched pairs were randomly assigned to treatment order (high-stimulation colored letters followed in 2 weeks by low-stimulation black letters or the reverse order) and to level of information (color added to difficult letter parts or added to randomly selected letters), counterbalanced for treatment order and level of information within each order. Errors and activity were subjected to a mixed-design analysis of covariance, with IQ the covariate. The major findings indicated that attention-problem adolescents performed better with high-stimulation task stimuli than with low, relative to the opposite performance pattern of controls. Different responding was significant for experimental but not for control children.This research was supported by National Institute of Mental Health Grant MH32282 to the first author. 相似文献
