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.
Data Collection by Survey01:07

Data Collection by Survey

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...
Systematic Sampling Method01:17

Systematic 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. Because measuring the entire population in a study is not practical, researchers use samples to represent the population of interest.
Systematic sampling is one of the simplest methods...
Stratified Sampling Method01:16

Stratified 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. The sampling method ensures that samples are drawn without bias and accurately represent the population. Because measuring the entire population in a study is not practical, researchers use samples to represent the population of interest.
To choose a stratified sample, divide the population into groups called strata and then take a...
Birth Control Methods01:22

Birth Control Methods

Vasectomy is a surgical form of male sterilization that involves severing and sealing the vasa deferentia, preventing sperm from mixing with semen during ejaculation. Because a vasectomy does not impact the testes' ability to produce testosterone, hormone levels, libido, and sexual function generally remain unchanged. While vasectomy is highly effective in preventing pregnancy, with a success rate near 99.85%, rare cases of recanalization (spontaneous reconnection) can occur. Although vasectomy...
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...

Area of Science:

  • Demography
  • Public Health Research Methodology

Background:

  • Conducting abortion surveys presents unique methodological challenges.
  • Accurate data on abortion is crucial for public health policy and reproductive health research.

Purpose of the Study:

  • To provide evidence-based recommendations for improving abortion survey methodology.
  • To share lessons learned from the Brazilian National Abortion Survey (PNA) to guide future research.

Main Methods:

  • The study details methodological aspects of the Brazilian National Abortion Survey (PNA).
  • Key techniques discussed include random sampling, household surveys, and the ballot-box method for sensitive data collection.
  • Emphasis is placed on questionnaire testing and validation procedures.

Main Results:

  • The PNA successfully employed the ballot-box technique in a large-scale, urban household survey.
  • Recommendations cover questionnaire design, pilot testing, and validation to ensure data quality.
  • The experience highlights the importance of culturally sensitive and rigorous data collection methods.

Conclusions:

  • Methodological rigor is essential for reliable abortion survey data.
  • The PNA's experience offers a valuable framework for conducting similar surveys globally.
  • Implementing recommended practices can enhance the validity and reliability of reproductive health research findings.
