Surveys02:16

Surveys

16.4K
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.

Naturalistic Observations

16.8K
If you want to understand how behavior occurs, one of the best ways to gain information is to simply observe the behavior in its natural context. However, people might change their behavior in unexpected ways if they know they are being observed. How do researchers obtain accurate information when people tend to hide their natural behavior? As an example, imagine that your professor asks everyone in your class to raise their hand if they always wash their hands after using the restroom. Chances...

Longitudinal Research

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...

Censoring Survival Data01:09

Censoring Survival Data

372
Survival analysis is a statistical method used to analyze time-to-event data, often employed in fields such as medicine, engineering, and social sciences. One of the key challenges in survival analysis is dealing with incomplete data, a phenomenon known as "censoring." Censoring occurs when the event of interest (such as death, relapse, or system failure) has not occurred for some individuals by the end of the study period or is otherwise unobservable, and it might have many different...

Data Collection III

The physical assessment examines the patient for objective data that defines the patient's condition, and aids in formulating the nursing care plan. The purpose of physical assessment is a health status appraisal, which includes identifying health problems, and establishing a database for nursing intervention.
The principles to begin the physical assessment include conducting a comprehensive or problem-related history in a quiet, well-lit room, emphasizing privacy and comfort for the...

Errors and Mistakes in Surveying01:19

Errors and Mistakes in Surveying

404
Errors and mistakes in surveying refer to inaccuracies in measurements and data recording. The errors are deviations from the actual value caused by human sensory limitations, equipment flaws, or environmental effects. These errors are typically unintentional and can result from the inherent imperfections in the instruments used, atmospheric conditions, or the observer’s inability to perceive exact measurements. On the other hand, mistakes are caused by the surveyor's lack of...

Summary

Ecological momentary assessment (EMA) survey incompletion is more likely in noisy environments. While this can bias data, the overall impact on self-report data is minimal.

Area of Science:

  • Audiology
  • Behavioral Science
  • Human-Computer Interaction

Background:

  • Ecological momentary assessment (EMA) surveys capture real-time experiences but can be perceived as intrusive.
  • Respondent burden in EMA may lead to survey incompletion, affecting data validity.

Purpose of the Study:

  • To investigate how environmental factors influence EMA survey incompletion.
  • To quantify the impact of survey incompletion on EMA self-report data.

Main Methods:

  • Observational study with 10 hearing aid users.
  • Utilized hearing aids with data loggers and a smartphone app to collect environmental data and survey responses.
  • Analyzed data to determine predictors of survey incompletion and its effect on reported experiences.

Main Results:

  • Survey incompletion was more frequent in noisy, speech-filled, or machine-dominated environments.
  • Incompletion rates increased when directional microphones and noise reduction were active.
  • Predicted responses suggested more challenging listening conditions during incompletion, but the overall data difference was small.

Conclusions:

  • EMA survey incompletion is systematic and influenced by environmental characteristics.
  • While incompletion can introduce bias, its effect on EMA self-report data is likely minor.
