Resumen
El diseño prospectivo de la investigación es crucial para los estudios médicos. Adherirse a un plan predefinido asegura resultados confiables, como lo demuestran los estudios Carvedilol Heart Failure y ELITE.
Área de la Ciencia:
- Metodología de la investigación médica.
- Diseño del ensayo clínico diseño del ensayo clínico.
- Investigación en salud pública.
Sus antecedentes:
- La difusión acelerada de los descubrimientos de tratamiento está aumentando la presión sobre la promulgación de la investigación.
- Los avances en computación facilitan el rápido intercambio de hallazgos médicos.
- Las enfermedades de salud pública requieren actualizaciones oportunas de la investigación.
Objetivo del estudio:
- Explicar la lógica del diseño prospectivo de la investigación en términos no matemáticos.
- Para resaltar la importancia de adherirse a un plan de investigación.
- Para ilustrar las consecuencias de abandonar la investigación prospectiva.
Principales métodos:
- Explicación de los principios de la investigación utilizando un lenguaje no matemático.
- Análisis del estudio de caso del programa estadounidense Carvedilol Heart Failure.
- Análisis del estudio de caso de la evaluación de losartan en los ancianos (ELITE). estudio.
Principales resultados:
- El diseño prospectivo de la investigación es vital para las conclusiones científicas válidas.
- Las desviaciones de un plan de investigación pueden conducir a resultados poco confiables.
- Es esencial adherirse a "primero diga lo que va a hacer, luego haga lo que dijo".
Conclusiones:
- Hacer hincapié en el papel crítico de la investigación prospectiva en la ciencia médica.
- Abogar por el cumplimiento riguroso de protocolos de investigación predefinidos.
- Subrayar el impacto negativo del abandono de las metodologías de investigación planificadas.

02:30Naturalistic Observations
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...
02:16Surveys
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.
01:40Archival Research
Some researchers gain access to large amounts of data without interacting with a single research participant. Instead, they use existing records to answer various research questions. This type of research approach is known as archival research. Archival research relies on looking at past records or data sets to look for interesting patterns or relationships. For example, a researcher might access the academic records of all individuals who enrolled in college within the past ten years and...
02:20Longitudinal 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...
01:50Cross-Sectional Research
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...
01:56Ethics in Research
Today, scientists agree that good research is ethical in nature and is guided by a basic respect for human dignity and safety. However, this has not always been the case. Modern researchers must demonstrate that the research they perform is ethically sound.
