Applied Research Approaches in Health Studies: Survey Approaches

These flashcards cover important vocabulary and concepts related to survey approaches in health studies, focusing on designs, sampling, and data collection processes.

Experimental Design

A research design where the researcher manipulates one or more independent variables to observe the effect on a dependent variable.

Quasi-Experimental Design

A type of research design that seeks to evaluate interventions but does not randomly assign subjects to groups.

Cross-Sectional Survey

A study that analyzes data from a population at one specific point in time.

Response Rates

The proportion of respondents who participate in a survey relative to the number of people invited.

Generalizability

The extent to which findings from a study can be applied to a larger population.

Non-Experimental Fixed Design

A research design that does not involve manipulation of an independent variable and often assesses multiple variables.

Power Analysis

A statistical method used to determine the sample size needed for a study to detect an effect if it exists.

Sampling Frame

A list of individuals from which a sample is drawn.

Probability Sampling

Sampling techniques where each member of the population has a known chance of being selected.

Non-Probability Sampling

Sampling techniques where the probability of any member being selected is not known.

Confidentiality

An ethical principle that ensures individual responses in a survey are kept private.

Anonymity

A condition in which respondents cannot be identified from the data collected.

Survey Design

The process of creating a survey instrument to gather data, including layout, questions, and response options.

Follow-Up Procedures

Steps taken after the initial survey is distributed to encourage responses, such as sending reminders.

Obtrusive Data

Data collected in a way that might affect how respondents answer questions, often leading to social desirability bias.

Sampling Plan

A strategy for defining the population, sample size, and sampling approach for a study.

Longitudinal Design

A research design that involves repeated observations of the same variables over short or long periods.

Survey Bias

Any bias that occurs when a survey produces results that are not representative of the population.
