Revista De Saude Publica
|December 19, 2013
Summary
The Brazilian Longitudinal Study for Adult Health (ELSA-Brasil) questionnaire was developed to assess adult health. This tool examines factors influencing health outcomes in Brazil.
Area of Science:
- Epidemiology
- Public Health
- Health Sciences
Context:
- The Brazilian Longitudinal Study for Adult Health (ELSA-Brasil) aims to understand complex health outcomes in the adult population.
- Existing research necessitates standardized measurement instruments for comparability and comprehensive data collection.
Purpose:
- To detail the development process of the ELSA-Brasil questionnaire.
- To outline the selection of relevant health topics and measurement instruments.
- To describe the methodology for sequencing questionnaire sections and pilot testing.
Summary:
- The ELSA-Brasil questionnaire development involved topic selection for a complex causal network of health outcomes.
- Measurement instruments, including neighborhood environment scales, depression/anxiety scales, and a food frequency questionnaire, were translated and adapted.
- Criteria for theme block sequencing and the importance of pretesting and pilot studies were addressed.
Impact:
- The ELSA-Brasil questionnaire will contribute original data on factors affecting adult health in Brazil.
- It will identify determinants and protective factors for various health outcomes.
- The study facilitates comparability with international health research.

1.3K
Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.

In cross-sectional research, a researcher compares multiple segments of the population at the same time. If they were interested in people's dietary habits, the researcher might directly compare different groups of people by age. Instead of following a group of people for 20 years to see how their dietary habits changed from decade to decade, the researcher would study a group of 20-year-old individuals and compare them to a group of 30-year-old individuals and a group of 40-year-old...

01:29Reliability and Validity
12.9K
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

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...

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...

Response Surface Methodology (RSM) is a collection of statistical and mathematical techniques used to develop, improve, and optimize processes. It is particularly valuable when many input variables or factors potentially influence a response variable.
