About this study

Official title: Design and Usability Testing of a Tailored Intervention to Increase Awareness About Sleep and Sleep Disorders Among Transportation Workers

The objective of this protocol is to conduct a focus group to identify OSA beliefs, attitudes, and knowledge among employees in the transportation industry on shift schedules.

Read the detailed description

Transportation shift workers (TSW, e.g., overnight, on-call, or rotating) have been identified as a high-risk group for health conditions (e.g., obesity, cardiovascular disease). Also, TSW are at risk for obstructive sleep apnea (OSA). According to one study, approximately 36% of TSWs have OSA, a condition that exacerbates health risks and daytime sleepiness. A recent report from the American Academy of Sleep Medicine (AASM) showed that those with untreated OSA cost on average $4,261 more than those without OSA. Also concerning, workers with OSA who are non-adherent to recommended OSA treatment (i.e., continuous positive airway pressure, CPAP) are at particularly high risk for motor vehicle accidents compared to those who are adherent.

This protocol outlines focus groups that will aim to identify knowledge, attitudes, and beliefs about OSA among TSW. Results of these focus groups will be used in future research to design a tailored website for relaying OSA information to TSW.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Personalized OSA messagesBehavioural

    Participants will receive personalized OSA messages designed to nudge and navigate them toward evaluation and treatment for OSA. Participants will complete questionnaires at baseline and at study follow-up.

  • ControlOther

    Participants will complete questionnaires at baseline and at study follow-up. At the end of the study period, participants will receive the OSA message intervention.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Obstructive Sleep Apnea (OSA) Self-efficacy

    The Survey of Obstructive Sleep Apnea Functional Health Literacy (SOFHL) was administered, which includes two subscales, one for OSA Self-Efficacy and another for OSA Knowledge. The SOFHL can be scored by measuring the proportion of correct answers in each sub-scale (OSA Self-Efficacy and OSA Knowledge). The OSA Self-Efficacy subscale collects responses to 5 self-efficacy questions on 3-point scales from 1 "I am confident" to 2 "I am not sure" and 3 "I am not confident." Scores of 1 ("I am confident") indicate self-efficacy. To score OSA Self-Efficacy, the total number of questions that participants mark a response of "1" ("I am confident") are summed then divided by the total number of questions in the subscale (5) and multiplied by 100. The result is a total score with a minimum possible value of 0% and a maximum possible value of 100%. Lower scores (closer to 0%) indicate low OSA self-efficacy scores. Higher scores (closer to 100%) indicate higher OSA Self-efficacy.

    Measured: Baseline and follow-up (approximately 2 months)

Secondary outcomes (2)
  1. OSA Knowledge

    The Survey of Obstructive Sleep Apnea Functional Health Literacy (SOFHL) was administered, which includes two subscales, one for OSA Self-Efficacy and another for OSA Knowledge. The SOFHL can be scored by measuring the proportion of correct answers in each sub-scale (OSA Self-Efficacy and OSA Knowledge). The OSA Knowledge subscale collects responses to 13 knowledge questions on 3-point scale from 1 ("I am confident this is true") to 2 ("I am not sure") and 3 ("I am confident this is not true"). To score OSA Knowledge, the total number of responses of 1 "I am confident this is true" are summed then divided by 13 and multiplied by 100. The result is a score with a minimum possible value of 0% and a maximum possible value of 100%. Lower scores (closer to 0%) indicate lower OSA knowledge while higher scores (closer to 100%) indicate higher OSA Knowledge.

    Measured: Baseline and follow-up (approximately 2 months)

  2. OSA Readiness to Change

    OSA Readiness to Change: A measure of willingness to improve sleep and address sleep problems. OSA readiness to change will be measured with a 12-item questionnaire. Responses are captured on a 5-item scale from 1 "strongly disagree" to 5 "strongly agree." Responses are summed for a total score of readiness to change. Higher scores indicate higher levels of readiness to change.

    Measured: Baseline and follow-up (approximately 2 months)

Model description
A 2-month pre-post pilot study will be conducted. Two worksites will be selected at random then randomized to either the tailored (intervention) or non-tailored (control) groups. Participants who fit the eligibility criteria will be recruited from each worksite and assigned to the study arm corresponding to their worksite (20 per worksite for a total of 40 participants).

Questions about this trial

What is this clinical trial studying?

A study testing Personalized OSA messages in people with Obstructive Sleep Apnea, run by Brigham and Women's Hospital at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 2 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 2 Oct 2026). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Obstructive Sleep Apnea (OSA) Self-efficacy (time frame: Baseline and follow-up (approximately 2 months)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Oct 2026.
