Research Tools and Measures
- Automated Self-Administered 24-hour Dietary Assessment Tool
The Automated Self-Administered 24-hour (ASA24®) Dietary Assessment Tool is a freely available web-based tool for epidemiologic, interventional, behavioral, or clinical research from NCI that enables multiple automatically coded self-administered 24-hour recalls and food records.
The Cancer Query Systems (CanQues) are applications that provide access to cancer statistics stored in online databases.
- CanStat Animator
The Cancer Statistics Animator (CanStat Animator) is a tool that allows users to animate cancer trends over time by cancer site and cause of death, race, and sex.
The Confidence Intervals for Ranks (CI*Rank) website presents confidence intervals for ranks of age-adjusted US cancer incidence and mortality rates by geographic region. Confidence intervals for ranks of age-adjusted US mortality rates for other causes of death are also provided.
- Classification of Laws Associated with School Students
Classification of Laws Associated with School Students (CLASS) is a scoring system that monitors and evaluates state-level school physical education and nutrition policies that have been codified into law. CLASS data, support materials, research briefs, and web-enabled tools for mapping nutrition and physical education policies nationally and for obtaining state-specific profiles have been organized in the CLASS website for use by the research community, educators, policy makers, and the public.
- Diet History Questionnaire III
The Diet History Questionnaire III (DHQ III) is a free food frequency questionnaire developed by NCI staff for use by researchers, clinicians, or teachers.
- Geographic Information Systems and Science for Cancer Prevention and Control
NCI's central source of information about GIS and related resources. It consists of an overview of GIS at NCI, examples of GIS tools and data, GIS research publications, and GIS-related funding opportunities.
- Grid-Enabled Measures
The Grid-Enabled Measures (GEM) site is a dynamic web-based collaboration tool that includes a repository of scientific measures organized by theoretical constructs. GEM is designed to enable users to come to agreement on the use of common measures using crowdsourcing to achieve insights on optimal measurement strategies. GEM can also be used to disseminate results of consensus initiatives for use by other researchers, practitioners, and clinicians.
The Health Disparities Calculator (HD*Calc) is designed to generate multiple summary measures to evaluate and monitor health disparities. The HD*Calc statistical software can be used either as an extension of SEER*Stat—allowing users to import Surveillance, Epidemiology, and End Results (SEER) data—or with other population-based health data.
HealthMeasures is an online resource that provides access to four person-centered measurement systems developed and validated with support from NIH, including the Patient Reported Outcomes Measurement Information System® (PROMIS®).
- Healthy Eating Index
The Healthy Eating Index (HEI) is a measure of diet quality, independent of quantity, that can be used to assess compliance with the US Dietary Guidelines for Americans and monitor changes in dietary patterns.
- NCI GeoViewer
An exploratory tool that enables users to construct comparative maps, graphs, and charts of cancer statistics and risk factors.
- Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events
The NCI Patient Reported Outcomes-Common Terminology Criteria for Adverse Events (PRO-CTCAE) is a patient-reported outcome measurement system developed to evaluate symptomatic toxicity in patients on cancer clinical trials. It was designed to be used as a companion to the Common Terminology Criteria for Adverse Events (CTCAE), the standard lexicon for adverse event reporting in cancer trials. PRO-CTCAE includes an item library of 124 items representing 78 symptomatic toxicities drawn from the CTCAE.
- Small Area Estimates for Cancer Risk Factors & Screening Behaviors
Model-based estimates for states, counties, and health service areas have been developed based on two surveys, the Behavioral Risk Factor Surveillance System (BRFSS) and the National Health Interview Survey (NHIS). The two surveys are combined using novel statistical methodology.
- SEER*Explorer SEER*Explorer is an interactive website to provide easy access to a wide range of SEER cancer statistics. It provides detailed statistics for a cancer site by gender, race, calendar year, age, and for a selected number of cancer sites, by stage and histology.
