The Early Childhood Longitudinal Study (ECLS) program provides data about the development of children in the United States. [1] It is carried out by the Institute of Education Sciences. It provides data on children's status at birth and at various points thereafter.
Single-subject research with a longitudinal study follow-up is a commonly-used approach. Current research is focused on integrating single-subject designs through meta-analysis to determine the effect sizes of behavioral factors in development. Lag sequential analysis has become popular for tracking the stream of behavior during observations.
Cross-sectional study: involves data collection from a population, or a representative subset, at one specific point in time. Longitudinal study: correlational research study that involves repeated observations of the same variables over long periods of time. Cohort study and Panel study are particular forms of longitudinal study.
A longitudinal study (or longitudinal survey, or panel study) is a research design that involves repeated observations of the same variables (e.g., people) over long periods of time (i.e., uses longitudinal data). It is often a type of observational study, although it can also be structured as longitudinal randomized experiment. [1]
There are several benefits to doing participant observation. Firstly, participant research allows researchers to observe behaviors and situations that are not usually open to scientific observation. Furthermore, participant research allows the observer to have the same experiences as the people under study, which may provide important insights ...
In marketing and the social sciences, observational research (or field research) is a social research technique that involves the direct observation of phenomena in their natural setting. This differentiates it from experimental research in which a quasi-artificial environment is created to control for spurious factors, and where at least one ...
The experience sampling method (ESM), [1] also referred to as a daily diary method, or ecological momentary assessment (EMA), is an intensive longitudinal research methodology that involves asking participants to report on their thoughts, feelings, behaviors, and/or environment on multiple occasions over time.

The Dunedin Multidisciplinary Health and Development Study (also known as the Dunedin Study) is a detailed study of human health, development and behaviour.Based at the University of Otago in New Zealand, the Dunedin Study has followed the lives of 1037 babies born between 1 April 1972 and 31 March 1973 at Dunedin's former Queen Mary Maternity Centre since their birth.
