Ethnic Identity within a Larger Culture01:27

Ethnic Identity within a Larger Culture

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

Reliability and Validity

12.8K
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

科学领域:

  • 儿科体育活动测量测量
  • 在研究合规性方面的行为科学.

背景情况:

  • 使用加速度计来准确测量幼儿的体力活动,由于不遵守佩戴时间和活动日志指令而受到阻碍.
  • 了解影响合规性的因素对于提高研究结果的有效性至关重要.

研究的目的:

  • 调查穿戴时间和活动日志完成与幼儿人口,社会经济和育儿风格变量之间的关系.
  • 为了确定幼儿的静坐时间是否根据活动日志完成而不同.

主要方法:

  • 从一项涉及父母和幼儿 (12-35个月) 的随机对照试验中获得的基线数据的二次分析.
  • 幼儿戴着ActiGraph wGT3x加速度计,家长填写活动日志.
  • 有效日需要至少600分钟的佩戴时间;分析包括ANOVA和千平方测试.

主要成果:

  • 50个家庭参与了调查,56%的家庭提交了有效的加速度计数据和活动日志.
  • 关系中的参与者更有可能完成活动日志 (P < .05).
  • 在没有完成活动日志的和没有完成活动日志的婴儿之间,没有发现婴儿静坐时间的显著差异.

结论:

  • 遵守磨损时间和完成活动日志的情况各不相同,返回的活动日志质量差影响了数据有效性.
  • 婚姻支持似乎是坚持学习幼儿体育活动研究研究方案的重要因素.
  • 需要改进的策略来提高基于加速度计的体育活动研究的合规性和数据质量.
