Study Notes

Research Ideas, Design, and Operationalization

Research starts with curiosity, exploring concepts through case studies, special populations, subtypes, or previous studies.
Understanding relationships between variables (e.g., risk factors, moderators, mediators) is a foundation for a study.
Operationalization turns abstract ideas into measurable concepts, avoiding oversimplification or adding unnecessary features.
For example, "stress" can be measured via surveys or physiological responses.
Research types include true experiments (high control, often in labs), quasi-experiments (less control), and case-control designs (comparing groups with and without a condition).
Research conditions are contrasted, such as laboratory vs applied research (real-world settings), and analogue vs clinical research (simplified vs real cases).
Efficacy (controlled environments) versus effectiveness (real-world clinical settings) in treatment tests.

Observational Research and Case-Control Studies

Observational research focuses on observing and analyzing existing conditions, rather than manipulating variables.
Case-control studies compare individuals with a condition (cases) to those without (controls).
Case-control studies can be cross-sectional (data collected at one point in time) or retrospective (examining past factors to explain outcomes).
Cohort studies follow groups over time to observe the development of outcomes.
Cohort studies can be single-group or multigroup designs, comparing groups based on different risk exposures.

Advanced Observational Research and Cohort Studies

Specifying constructs (clearly defining variables) is crucial for observational studies.
Properly selecting groups (representative samples avoiding bias) is necessary for valid results.
A clear timeline is important in establishing causality, especially in retrospective analysis.
Cohort designs are adept at tracking long-term effects and establishing causality, but can be time-consuming and expensive.
Observational designs may rely heavily on data collection and study participants at different timelines.

Observational Research Overview

Observational research examines existing conditions without manipulation and explores associations to generate hypotheses and understand outcomes in real-world settings.

Case-Control Designs in Detail

These studies compare two groups—cases (individuals with a condition) and controls (without).
Cross-sectional studies gather data at one point in time—e.g., comparing stress levels in groups with and without anxiety.
Retrospective approaches analyze past conditions—e.g., studying early attachment in suicidal vs non-suicidal youth.

Cohort Designs

Cohort studies follow groups of individuals over time to observe how outcomes develop.
Single-group cohorts share a common characteristic, like birth year.
Multigroup cohorts compare different exposure groups.
Accelerated multicohort designs observe groups at different ages simultaneously to cover time frames rapidly.
