Surveys02:16

Surveys

14.7K
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.

Nursing Evaluation01:15

Nursing Evaluation

3.3K
The evaluation stage signals the end of the nursing process. The nurse gathers evaluative data to assess whether or not the patient has attained the expected results. Whereas the nurse collects data in the nursing assessment to identify the patient's health concerns, the evaluation stage data determines if the indicated health issues are resolved. Evaluative data collection includes two sections: the data acquired to evaluate patient outcomes and the time criteria for data collection.

Nursing Process for Patient and Caregiver Teaching III: Evaluation and Documentation

1.7K
Evaluation of the teaching process enables the nurse to determine if the patient's learning needs were met and if training was effective. If the expected outcomes are not met, the care plan is revised, and additional education or reinforcement is provided. Nurses can ask questions after the session or obtain feedback to assess the patient's understanding of the topic.
Nurses can use several methods to evaluate patient outcomes. For example, oral questions can assess cognitive learning,...

Social Loafing01:37

Social Loafing

34.8K
Another way in which a group presence can affect performance is social loafing—the exertion of less effort by a person working together with a group. Social loafing occurs when our individual performance cannot be evaluated separately from the group. Thus, group performance declines on easy tasks (Karau & Williams, 1993). Essentially individual group members loaf and let other group members pick up the slack. Because each individual’s efforts cannot be evaluated,...

Reliability and Validity01:29

Reliability and Validity

12.7K
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.

Review and Preview

In statistics, several tools are used to interpret the data. Measures of central tendency represent the characteristics of the data, such as mean, median, and mode. Additionally, measures of variance like standard deviation and range are used to find the spread of data from the mean. Relative standing measures the distance between data locations. Commonly used measures of relative standings are percentile, z score, and quartiles.
Percentiles are a type of fractile that partition data into...

Summary
This summary is machine-generated.

Family medicine clerkship assessments show low correlations, indicating they measure different learning objectives. Replacing in-house exams with standardized ones improved validity, suggesting periodic assessment review is beneficial.

Area of Science:

  • Medical Education
  • Assessment in Medical Training

Background:

  • Family medicine clerkships require diverse assessment tools to evaluate a broad range of objectives.
  • A single assessment cannot capture the full scope of student learning.
  • Ensuring the longitudinal accuracy and validity of assessments is crucial.

Purpose of the Study:

  • To investigate the relevance and validity of various assessment tools used in family medicine clerkships.
  • To understand the correlation between different assessment methods in evaluating medical students.
  • To assess the psychometric properties of family medicine clerkship assessments.

Main Methods:

  • Retrospective correlation analysis of student scores across multiple assessment tools.
  • Comparison of individual assessment scores for 267 family medicine clerkship students.
  • Defined correlation thresholds: weak (ρ<0.3), moderate (0.3-0.5), high (ρ>0.5).

Main Results:

  • Low correlations were observed between clinical evaluations and case-based short-answer questions (ρ=0.165) and objective structured clinical examinations (OSCEs) (ρ=-0.246).
  • Unexpectedly high correlation was found between multiple-choice questions and OSCEs.
  • Preliminary analysis with a standardized exam showed weaker correlation with OSCEs, as expected.

Conclusions:

  • Low correlations between assessments are expected as they measure different objectives, supporting discriminant validity.
  • Higher correlations between component scores suggest convergent validity.
  • Replacing in-house multiple-choice questions with a standardized exam improved assessment validity, highlighting the value of periodic review and standardized testing.
