DECIDE: Developing Tools for Lung Cancer Screening Discussion Improvement (DECIDE)

August 14, 2024 updated by: Lisa Carter-Bawa, PhD, Hackensack Meridian Health

Using a Mixed Methods Approach to Understand Shared Decision-Making in Lung Cancer Screening

The purpose of this study is to learn about discussion between clinicians and their patients related to lung screening. Survey answers will be collected from both clinicians and their patients.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 80 years (Adult, Older Adult)

Accepts Healthy Volunteers

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Clinicians
Primary care clinicians (general internists, family physicians, nurse practitioners, physician assistants) who treat lung cancer screening eligible patients
Behavioral: Primary Care Clinicians' Lung Cancer Screening Survey
Includes items to assess attitudes, barriers, and knowledge of lung cancer screening guidelines.
Smokers/Former Smokers
Current smoker or former smoker who has quit within the past 15 years
Behavioral: Cataldo Lung Cancer Stigma Scale (Smoking-Related Subscale)
Perceived Smoking-Related Stigma will be measured using the 5-item Cataldo Lung Cancer Stigma Scale (Smoking-Related Subscale). The response scale is 1 = strongly disagree, to 4 = strongly agree, and scores range from 5 to 25 (high stigma). Cronbach's alphas were 0.75 to 0.89 in prior studies.
Behavioral: Patient Trust in the Medical
Medical Mistrust will be measured using the 5-item Patient Trust in the Medical Profession Scale.80 The five-point Likert responses measure the extent to which patients perceive their clinician to be honest, caring more about convenience, thorough and careful, and trusted. The range of scores is 5 to 25 (higher mistrust). Reliability and validity have been well established with a Cronbach"s alpha of 0.84.
Behavioral: Stage of Readiness for Smoking Cessation - Contemplation Ladder
Among current smokers
Behavioral: Decision Conflict Scale (DCS) - Lung Cancer Screening
The DCS is a 16-item Likert-response item scale that has been modified for the lung cancer screening and smoking cessation contexts. The DCS was developed by O"Connor,74-75 and validated in many health decisions including breast cancer screening with Cronbach"s alphas ranging from 0.78 to 0.81. 74-75 Despite its name, the DCS measures more than decision conflict to encompass personal perceptions of perceived decision-making quality such as feeling the choice is informed, values based, and likely to be implemented as well as expressing satisfaction with the decision. 74-75 The DCS is comprised of items with response options ranging from 1 (strongly disagree) to 5 (strongly agree). The items are summed to total scale score with lower scores reflective of higher decision conflict and higher scores reflective of lower decision conflict.
Other Names:
  • DCS
Behavioral: Shared Decision Making Questionnaire (SDM-Q)- Patient
Shared Decision Making Process will be measured from the patient perspective using the 9-item Shared Decision Making Questionnaire (SDM-Q-9),77 which has been validated with a Cronbach"s alpha of 0.94.
Other Names:
  • SDM-Q-9

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Key Components of Shared Decision Making Process That Predict Patient-perceived Lung Cancer Screening Decision Quality
Time Frame: at baseline (study enrollment)
Decisional Quality was measured using the multidimensional Decisional Conflict Scale, a 16-item Likert-response scale that was modified by the investigators for the lung cancer screening context. The total score ranging from 0 to 64. This total score is commonly transformed into a standardized score that falls within a 0 to 100 range. Decisional quality measured on this numeric scale from which lower scores represent lower decisional conflict and, therefore, higher decisional quality. Scores below 25 have been associated with low decisional conflict.

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date.

The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
