Any commonly known scales used to collect data for the study (e.g., psychological scales such as MMPI and CPI, or occupational scales such as the Census Occupational Codes). The inclusion of a common scale should be identified in the documentation associated with this dataset and confirmed by variable names or labels. If the questionnaire used has a finite list of responses, such as 'Always,' 'Sometimes,' 'Rarely,' and 'Never,' or 'Strongly Agree,' 'Agree,' 'Disagree,' and 'Strongly Disagree,' then 'A Likert-type scale was used' or 'Several Likert-type scales were used' is entered in this field. The scales can be cited either as a list or described in full sentences.

Scales

Software Applications

The time dimension in which the data were collected and framed, ex. longitudinal, cross-sectional, etc.</div><ul><li>Longitudinal -- Data collected repeatedly over time to study change in a population.</li><li>Longitudinal:Cohort/Event-based -- Data collected over time about a group of individuals that are connected in some way or have shared some significant experience within a given period. Examples: birth, disease, education, employment, family formation, participation in an event.</li><li>Longitudinal:Trend/Repeated Cross--section -- Studies different samples /groups of people from the same population at several points in time, using the same set of questions/variables. Conclusions are drawn for the population. Examples: public opinion polls, elections studies, etc.</li><li>Longitudinal:Panel -- Data collected over time from, or about, the same sample of respondents.</li><li>Longitudinal:Panel:Continuous -- Reports from the panel are collected on a regular basis.</li><li>Longitudinal:Panel:Interval -- Measurements are taken only when information is needed.</li><li>Time Series -- Data collected repeatedly over time to study change in observations. These are typically 'objective' measurements of phenomena that can be observed externally, as opposed to attitudes/opinions or feelings. Examples: economic/financial indicators, natural/meteorological phenomena, vital statistics, etc.</li><li>Time Series:Continuous -- Phenomena are measured at every instant of time. Examples: lie detectors, electrocardiograms, etc.</li><li>Time Series:Discrete -- Measurements are taken at (usually regularly) spaced intervals. Examples: macroeconomics (weekly share prices, monthly profits, sales, etc.), meteorology (daily rainfall, hourly temperature, etc.), sociology (crime figures, employment figures, etc.).</li><li>Cross-sectional -- Data about a population are obtained only once.</li><li>Cross-sectional ad-hoc follow-up -- Data collected at one point in time to complete information collected in a previous cross-sectional study; the decision to collect follow-up data is not included in the study design.</li></ul>

Time Methods

Lists significant variables that are present in the data files distributed for public release, particularly demographic variables.

Variable Description

Methodology

Tells when the data were physically collected. The Collection Time Frame field is a text description of the collection dates or collection date ranges.

Collection Dates

A description of technical details and other characteristics of the data collection (such as unique authoring, dissemination, or processing information) that cannot be recorded in the other metadata fields but constitute important information for the user.

Notes

The group of persons or other elements that are the object of the study and to which the study results refer. Age, nationality, and residence commonly help to delineate a given universe, but any of a number of factors may be involved, such as sex, race, income, veteran status, criminal convictions, etc. The universe may consist of elements other than persons, such as housing units, court cases, deaths, countries, etc. In general, it should be possible to tell from the description of the universe whether a given individual or element (hypothetical or real) is a member of the population under study.

Universe

Scope

Date when the data collection was first distributed by ICPSR.

Original Release Date

A summary description of changes that have been made to the data collection since its last release. This field constitutes the de facto change history for a data collection.

CDS-2020&nbsp;time&nbsp;diary&nbsp;weights are provided
as “User Generated” Data through OpenICPSR. Due to a low response rate and
small sample size for the&nbsp;CDS-2020&nbsp;time&nbsp;diaries, these weights are considered unofficial and
being made available to researchers who understand the limitations (and
potential uses) of these data.&nbsp;CDS-2020&nbsp;was
a follow-up data collection in the Fall of&nbsp;2020&nbsp;during
the Covid-19 pandemic for children who participated in the 2019 wave of&nbsp;CDS. Children’s&nbsp;time&nbsp;diaries
in&nbsp;CDS-2020&nbsp;were
collected for a random week day and a random weekend day.
