Convenience Sampling Method00:55

Convenience Sampling Method

Sampling is a technique to select a portion (or subset) of the larger population and study that portion (the sample) to gain information about the population. Data are the result of sampling from a population. The sampling method ensures that samples are drawn without bias and accurately represent the population.
Convenience sampling is a non-random method of sample selection; this method selects individuals that are easily accessible and may result in biased data. For example, a marketing...
Surveys02:16

Surveys

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.

Assessment of blood pressure in brachial artery(two-step method)

Measuring blood pressure is a fundamental skill in healthcare that aids in diagnosing and monitoring hypertension and other cardiovascular conditions. An aneroid sphygmomanometer, commonly used in clinical settings, offers a manual and precise method for blood pressure measurement. The technique for using this instrument involves specific steps that must be carefully executed to ensure accuracy. The following detailed description outlines a two-step technique for assessing blood pressure using...

Measurement of Bioavailability: Pharmacokinetic Methods

Pharmacokinetics is a vital branch of pharmacology that examines how drugs are absorbed, distributed, metabolized, and excreted by the body. Two key methodologies in pharmacokinetics are plasma drug concentration studies and urinary drug excretion analyses, both of which provide critical insights into a drug's therapeutic efficacy and bioavailability.Plasma Drug Concentration-Time StudiesPlasma drug concentration-time studies involve analyzing blood samples at specific intervals to quantify...

Summary
This summary is machine-generated.

Beverage intake survey questions for adolescents correlate with detailed dietary recalls but measure frequency, not exact servings. These surveys are valuable for tracking population beverage consumption trends.

Area of Science:

  • Nutrition science
  • Dietary assessment methodology
  • Adolescent health

Background:

  • Accurate assessment of beverage intake in adolescents is crucial for public health.
  • Existing survey methods require validation against criterion standards.
  • Understanding beverage consumption patterns informs targeted interventions.

Purpose of the Study:

  • To evaluate the validity of 7 specific beverage intake survey questions.
  • To compare survey data with criterion 24-hour dietary recalls (24HrDRIs) in adolescents.
  • To determine the utility of survey data for nutritional surveillance.

Main Methods:

  • Utilized data from 610 US high school students.
  • Compared mean beverage intake (times/day) from surveys to servings/day from ≥3 24HrDRIs.
  • Assessed agreement on the proportion of students reporting intake ≥1 time/day.

Main Results:

  • Survey data showed significant correlations with 24HrDRI data (corrected r: 0.26-0.49).
  • Discrepancies were observed between survey and 24HrDRI results for 5 specific beverages.
  • Reported intake frequencies from surveys did not directly equate to servings/day.

Conclusions:

  • Beverage intake survey questions are best reported as times/day, not a direct proxy for servings/day.
  • These survey questions demonstrate utility for population-level surveillance of adolescent beverage intake.
  • The methodology supports monitoring beverage consumption trends over time in adolescent populations.
