Surveys02:16

Surveys

17.3K
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.

Dose-Response Relationship: Selectivity and Specificity

10.8K
Drugs exert their therapeutic effects by interacting with receptors, enzymes, or ion channels that are present throughout the human body. The strength and duration of the interaction between a drug and its target receptor are characterized by the selectivity and specificity of the drug. Selectivity refers to a drug's strong preference for its intended target over other targets. For instance, isoprenaline, a non-selective β-adrenergic agonist, interacts with both β1- and...

Convenience Sampling Method00:55

Convenience Sampling Method

12.3K
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...

Data Collection by Survey01:07

Data Collection by Survey

9.7K
The systematic method of obtaining and analyzing accurate information of a population is called data collection. A survey is a standard method of data collection that involves collecting information from a target human population about their experience, opinion, or knowledge of a product, service, or process. The responses are recorded and interpreted. The most common survey examples are written questionnaires, face-to-face or telephonic conversations, focus groups, and electronic (e-mail or...

Data Collection by Observations

15.8K
Data collection refers to a systematic way of obtaining, observing, measuring, and analyzing accurate information. Observational studies are one of the most widely used methods of data collection. It involves collecting data by observing the behavior and physical characteristics of a sample without making any modifications to the sample.
An astronomer viewing the motion and brightness of stars in the sky and recording the data is an example of observational data collection. A botanist recording...

Longitudinal Research02:20

Longitudinal Research

13.7K
Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

Area of Science:

  • Longitudinal survey methodology
  • Social science research
  • Data linkage studies

Context:

  • The lidA Study aims to link survey data with social security and health insurance claims.
  • Obtaining multiple respondent consents for data storage and linkage presents methodological challenges.

Purpose:

  • To assess the feasibility of obtaining three distinct consents within a single longitudinal study.
  • To determine if the consent process introduces selectivity bias in the study sample.

Summary:

  • A cohort study of 6,585 employed individuals subject to social security contributions was analyzed.
  • Selectivity analyses confirmed that the initial sample was representative and unbiased.
  • All three required consents (panel participation, social security data linkage, health insurance claims linkage) were obtained without significant bias.

Impact:

  • Demonstrates that high consent rates for sensitive data linkage are achievable.
  • Highlights the importance of question placement and data transparency in participant engagement.
  • Provides a methodological precedent for future longitudinal studies requiring multiple data linkages.
