Trial Outcomes & Findings for Evaluation of National Cancer Institute (NCI) Smoking Intervention Resources (NCT NCT01342523)
NCT ID: NCT01342523
Last Updated: 2015-10-14
Results Overview
Abstinence will be defined as 7-day point prevalence.

1034 participants
Measured after the 3 month follow up assessment
2015-10-14
Participant Flow
The recruitment period ran from November 28, 2011 through March 26, 2013. All study participants were recruited through the portal to the smokefree.gov website.
Prior to randomization, potential participants were asked to make a "confirmation" call to an automated answering system to confirm willingness to perform study procedures. The call was intended to increase the likelihood that individuals would take treatment and follow-up calls. Randomization occurred immediately after the confirmation call.

Outcome measures

Cancer Information Service Counseling ("CIS")
n=453 Participants
Participants in this intervention group received telephone quitline counseling from the Cancer Information Service (CIS). These proactive calls initiated by CIS included an initial call (30 min), occurring within 3 days of enrollment, plus 4 additional counseling calls (up to 15 min each) scheduled to occur on the quit day or the day after, and then weekly for the next 3 weeks. The content of the counseling calls focused initially on motivating quitting and then setting a quit date, providing support, building self-efficacy, and skill training. The CIS intervention group will be compared to a "No CIS" group. The original randomization plan called for approximately half of the total sample of 1034 participants to be randomized to this intervention group (CIS) and the other half to the No CIS intervention group. However, due to a problem in the electronic transfer of data from the research coordinating site to CIS, 453 participants were randomized to CIS and 581 to the "No CIS" group.
|
No Cancer Information Service Counseling ("No CIS")
n=581 Participants
Participants in this intervention group did not receive telephone quitline counseling from the Cancer Information Service (CIS). This intervention group will be compared to an intervention group that did receive telephone quitline counseling from the CIS. The original randomization plan called for approximately half of the total sample of 1034 participants to be randomized to this intervention group (No CIS) and the other half to the CIS intervention group. However, due to a problem in the electronic transfer of data from the research coordinating site to CIS, 581 participants were randomized to "No CIS" group and 453 to the CIS group.

Nicotine Replacement Therapy (NRT; Mini-Lozenge for 2 Weeks)
n=518 Participants
Participants in this intervention group received a 2-week starter package of nicotine mini-lozenges, with dose based on time to since first cigarette of the day as per package instructions. Each package contained 2 mini-lozenge dispensers (162 lozenges total) and instructions on proper use. Approximately half of the total sample of 1034 participants was randomized to receive the 2-week supply of mini-lozenges; the other half received no mini-lozenges.
|
No Nicotine Replacement Therapy
n=516 Participants
Participants in this intervention group received no nicotine replacement therapy (NRT), i.e., no nicotine mini-lozenges. Approximately half of the total sample of 1034 participants was randomized to receive no NRT; the other half a 2-week supply of nicotine mini-lozenges.
|
Email Messaging
n=526 Participants
Participants Email Messaging intervention group received brief email messages that could be accessed by any computer or mobile device that allowed email receipt. Messages were intended to provide: (1) Motivation/encouragement; (2) Quitting tips and information; (3) Adherence/education prompts (to use available resources as recommended), and (4) relapse prevention content. These emailed messages were sent twice/day for two weeks, once/day for an additional month, and then one every 3rd day for an additional 6 weeks (constituting a 3-month-long intervention). Approximately half of the total sample of 1034 participants was randomized to receive Email Messaging; the other half received no Email Messaging.
|
No Email Messaging
n=508 Participants
Participants in this intervention group received no Email Messaging. Approximately half of the total sample of 1034 participants was randomized to receive no Email Messaging; the other half received 3 months of Email Messaging.

Full SmokeFree.Gov Website
n=525 Participants
Participants in the Full SmokeFree.gov website intervention group received the standard smokefree.gov website content that included resources to motivate quitting and a step-by-step quitting guide that provided a skill-based intervention for preparing to quit, quitting, and maintaining abstinence. In addition, the active website offered encouragement and support, motivational information, and interactive features and referral links. The active website did not include direct interaction with users (e.g. live help) or interactive audio or video content. User-engagement features included task charts for behavior change, self-monitoring tools (e.g. for cravings and self-assessment), creation of a personal calendar, links to a quitline or to a counselor via text message for live help and social support through social media. No tailoring, feedback or outbound reminders were in use. Approximately half of the total sample of 1034 participants was randomized to receive the Full Smoke
|
Lite SmokeFree.Gov Website
n=509 Participants
Participants in the Lite SmokeFree.gov Website intervention group received received the "Lite" version of the website (developed by the investigators for this research) that included information about smoking and health such as benefits of quitting and information about withdrawal, medications and stress, but contained no interactive features or content that would support skill training. The look and graphics directly mirrored the full smokefree.gov website, but the number of web pages was reduced from over 50 to 16, and external links to resources were virtually eliminated. Approximately half of the total sample of 1034 participants was randomized to receive theLite SmokeFree.gov Website; the other half received the Full SmokeFree.gov Website.
|
Full Cessation Booklet
n=517 Participants
Participants in the Full Cessation Booklet intervention group received the National Cancer Institute's 36-page "Clearing the Air" brochure (www.smokefree.gov/pubs/clearing\_the\_air.pdf), containing a detailed guide for preparing to quit, quitting, and preventing relapse as well as suggested resources. Approximately half of the total sample of 1034 participants was randomized to receive the Full Cessation Booklet; the other half received a Brief Cessation Booklet.
|
Brief Cessation Booklet
n=517 Participants
Participants in the Full Cessation Booklet intervention group received a 12-page booklet developed by the investigators. The content of this booklet was the same as contained in the 36-page "Clearing the Air" booklet except that information directly relevant to coping skill training (identification of smoking triggers, making coping plans) was removed. Approximately half of the total sample of 1034 participants was randomized to receive the Brief Cessation Booklet; the other half received the Full Cessation Booklet.
