大学生寻求专业性心理帮助态度的研究

寻求专业性心理帮助是大学生解决心理问题的前提和关键,与其心理健康知识的掌握和人格密切相关。心理健康知识掌握较少的大学生对于寻求专业性心理帮助持消极态度,反之,则持积极态度。大学生人格维度中的神经质与外显态度有显著的正相关;精神质与外显态度存在显著负相关;内外倾与外显态度相关不显著,与内隐态度有显著负相关。     

Recent progresses in outcome-dependent sampling with failure time data

An outcome-dependent sampling (ODS) design is a retrospective sampling scheme where one observes the primary exposure variables with a probability that depends on the observed value of the outcome variable. When the outcome of interest is failure time, the observed data are often censored. By allowing the selection of the supplemental samples depends on whether the event of interest happens or not and oversampling subjects from the most informative regions, ODS design for the time-to-event data can reduce the cost of the study and improve the efficiency. We review recent progresses and advances in research on ODS designs with failure time data. This includes researches on ODS related designs like case–cohort design, generalized case–cohort design, stratified case–cohort design, general failure-time ODS design, length-biased sampling design and interval sampling design.
