Clinical trials data

Cue Reactivity Task in substance use and addiction trials: 158 registered studies

Every registered substance use and addiction study on ClinicalTrials.gov that names the Cue Reactivity Task in an outcome measure: how often it is a primary outcome, the tests named with it, how large the studies are and when they measure it.

These counts cover cue reactivity tasks with any cues: drug, alcohol and smoking cues as well as food. The library's version, the Food Cue Reactivity Task, shows food.

Questions, answered from the data

How many substance use and addiction trials use the Cue Reactivity Task?

158 registered substance use and addiction studies on ClinicalTrials.gov name it in an outcome measure, 89 of them in a primary outcome: 18% of the condition's 895 studies with a cognitive outcome, against 1% of all of them. It is the test substance use and addiction trials name most.

Which tests do substance use and addiction trials use with the Cue Reactivity Task?

The Stop-Signal Task (16 studies), the Go/No-Go Task (10 studies) and the Dot-Probe Task (9 studies).

How many participants do phase 2 substance use and addiction trials that use the Cue Reactivity Task enroll?

Half of the phase 2 studies that name it enroll 50 participants or fewer, and the middle half enroll 31 to 76. 47 of them give a size.

When do substance use and addiction trials measure the Cue Reactivity Task?

Half of the primary outcomes that name the Cue Reactivity Task are measured within 2 weeks of the start, and the middle half from the first day to 5 weeks. 73 primary outcomes give a duration.

How many completed substance use and addiction trials that use the Cue Reactivity Task have reported results?

49 of the 86 completed studies that name it, 57%, have reported results: 36 posted them on ClinicalTrials.gov, 27 have a results paper linked to the registry record, and 14 did both. The other 37 show neither. Of all completed studies with a cognitive outcome, 46% have reported results.

How the studies are counted

For each test family, the census runs ClinicalTrials.gov's own outcome search for the family's names and reads every study first posted by the day the family was counted. These studies were read on 10 November 2026. A study counts once on a page, however many tests it names. Counts for a test cover every version of the task under any of its names, so a page can count studies that used a commercial version.

The census adds two things to each record and changes nothing in it: which outcome list names the test (primary, then secondary, then other), and the condition groups, matched on the study's condition names and MeSH terms. A study can fall in several groups; one whose only condition is cognitive impairment or decline falls in “Cognitive impairment and decline”. Studies that name only instruments outside the library count in every total and share but are not listed.

A second read on 10 November 2026 added each study's overall status, whether results are posted, its intervention types, the countries of its sites and the time frame of the outcome that names each test. A time frame counts by the latest time point it names: “Baseline, 12 and 24 weeks” is 24 weeks, a single visit is within a day, and one that names no duration, such as “end of treatment”, is left out of the timings.

A third read on 10 November 2026 added the papers the registry links to each study: those its sponsor lists as reporting results, and those PubMed links to it through the study's NCT number. A study has a results paper when one of them came out in or after the month of its primary completion and PubMed does not class it as a protocol, review or comment. A paper that never gives the NCT number is not linked, so some studies counted as reporting neither did publish.

Source: ClinicalTrials.gov, a database of the U.S. National Library of Medicine, which does not endorse these pages. Every study line is in the data release 2.1.0, and the explorer's own file is clinical-trials-studies.json.
