  5. To evaluate patient perspectives on the intervention.
  6. To evaluate the rate of TGT among Black or African American men with prostate cancer who have received the tumor genetic pre-test counseling tool.

OUTLINE:

This is a two-stage study. In Stage 1, Adult Black or African American men with metastatic prostate cancer who have not made a decision about TGT, or who have decided to undergo TGT, or patients who have decline TGT about tumor genetic testing will participate in development by answering questionnaires and utilizing the pilot application for up to 60 days. The investigators will then refine the tool to be piloted in Stage 2.

Stage 2: A pilot study of participants who are planning to have a discussion about undergoing tumor genetic testing with their oncology provider will be invited to join and utilize the tool, and answer questionnaires about the tool.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Stage 1: Tool Development
Participants will participate in a semi-structured qualitative interview either by phone, video conference or in-person. A trained interviewer will interview eligible, consenting participants using a semi-structured interview guide to meet objectives. The interview guide is based on The Patient Education Materials Assessment Tool (PEMAT) and the COM-B (capability (C), opportunity (O), and motivation (M))/Behaviour Change Wheel (BCW) framework and will be used to determine an implementation strategy. The interview will be audio-recorded, transcribed verbatim, and analyzed.
Non-therapeutic educational intervention
Participants will complete questionnaires online, via mail, by telephone, or in person per participant preference.
Other Names:
  • Surveys
Experimental: Stage 1: Tool Implementation (Pilot Study)
Participants will receive the tumor genetic pre-test counseling tool informed by results and themes identified in Stage 1. Participants will receive the non-therapeutic intervention, a pre-TGT counseling tool, and complete pre- and post-intervention surveys and a attend a brief post-intervention interview.
Non-therapeutic educational intervention
Participants will complete questionnaires online, via mail, by telephone, or in person per participant preference.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Frequency of participant responses (Stage 1)
Time Frame: 1 day
Participant-reported perspectives of intervention in a semi-structured interview will be collected during Stage 1 and reviewed and will be explored using thematic analysis. A codebook will be created using the PEMAT (for the primary objective) described in the interview guide. This framework provides a systematic approach for identifying behavior change models evaluated according to three criteria: comprehensiveness, coherence, and a clear link to an overarching model of behavior. This will produce evidence-based behavior change techniques most likely to be effective. Emergent codes and themes will be added throughout thematic analysis. Two coders will code each interview (one primary and one secondary coder). Discrepancies will be negotiated to consensus.
1 day
Proportion of enrolled participants (Stage 2)
Time Frame: 1 day
The proportion of participants who enrolled in the study after being approached by their healthcare team will be reported.
1 day
Proportion of enrolled participants who review all educational materials (Stage 2)
Time Frame: Up to 60 days
The proportion of all enrolled participants who utilized and reviewed all of the educational materials in the tool will be reported.
Up to 60 days
Mean score of Feasibility of Intervention Measure (FIM) (Stage 2)
Time Frame: Up to 60 days
Scores on the FIM will be averaged across all participants. Items will be scored on a 5-point scale: 1= Completely disagree, 2 = Disagree, 3 = Neither agree nor disagree, 4 = Agree, 5= Completely agree. A higher mean score indicates greater feasibility. The mean score and standard deviation will be reported.
Up to 60 days

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Mean score of Acceptability of Intervention Measure (AIM) (Stage 2)
Time Frame: Up to 60 days
Scores on the AIM items will be averaged across all participants. Items will be scored on a 5-point scale: 1= Completely disagree, 2 = Disagree, 3 = Neither agree nor disagree, 4 = Agree, 5= Completely agree. A higher mean score indicates greater feasibility. The mean score and standard deviation will be reported.
Up to 60 days
Mean score of investigator-developed, measure of acceptability items (Stage 2)
Time Frame: Up to 60 days
Scores on the 5-item investigator-developed, measure of acceptability will be scored on a 5-point scale: 1= Completely disagree, 2 = Disagree, 3 = Neither agree nor disagree, 4 = Agree, 5= Completely agree. A higher mean score indicates greater feasibility. The mean score and standard deviation will be reported. However, responses will not be averaged to across items; each item will be analyzed independently.
Up to 60 days
Mean score of cancer genomic testing knowledge (Stage 2)
Time Frame: Up to 60 days
Knowledge of tumor genetic testing adapted from a validated survey from Blanchette, et al.+ select questions from a survey from Rogith, et al.will be utilized to measure the level of cancer genomic testing knowledge. "Don't know" will be scored as incorrect. The proportion of correct responses will be calculated to generate a total score between 0-100, with a higher score indicating greater knowledge. No items will be weighted. Since all items are required, we anticipate missing responses will be rare. Any missing data will be managed case-by-case post-hoc.
Up to 60 days
Proportion of participants who select correct response in each genomic testing knowledge instrument item (Stage 2)
Time Frame: Up to 60 days
Knowledge of tumor genetic testing adapted from a validated survey from Blanchette, et al. including select questions from a survey from Rogith, et al. and is designed to measure the level of cancer genomic testing knowledge. Responses of "Don't know" will be scored as incorrect. Each of the item scores will be reported as a proportion of the participants who answered each item correctly. Since all items are required, we anticipate missing responses will be rare. Any missing data will be managed case-by-case post-hoc.
Up to 60 days
Proportion of participants who answer "Yes" to each attitude item in the Attitude and expectations for tumor genetic testing survey (Stage 2)
Time Frame: Up to 60 days
Attitude and expectations measure for tumor genetic testing is a 17-item measure adapted from a validated survey from Blanchette, et al. including one open-ended investigator-created item. Items on the attitude scoring scale range from "Yes" = 1 and "No" or "Unsure" = 0.
Up to 60 days
Proportion of participants who answer "Strongly Agree" or "Agree" to the expectation item in the Attitude and expectations for tumor genetic testing survey (Stage 2)
Time Frame: Up to 60 days
The attitude and expectations for tumor genetic testing is a measure adapted from a validated survey from Blanchette, et al. and includes one open-ended investigator-created item. The expectations scoring (item 3): "Strongly Agree" or "Agree" = 1 and all other responses = 0
Up to 60 days
Participant-reported perspectives of intervention in a semi-structured interview. (Stage 2)
Time Frame: Up to 60 days
Participant-reported perspectives of intervention in a semi-structured interview will be collected during Stage 1 and reviewed and will be explored using thematic analysis. A codebook will be created using the COM-B ((capability (C), opportunity (O), and motivation (M) / BCW domains (for the secondary objectives) described in the interview guide. This framework provides a systematic approach for identifying behavior change models evaluated according to three criteria: comprehensiveness, coherence, and a clear link to an overarching model of behavior. This will produce evidence-based behavior change techniques most likely to be effective. Emergent codes and themes will be added throughout thematic analysis. Two coders will code each interview (one primary and one secondary coder). Discrepancies will be negotiated to consensus.
Up to 60 days
Proportion of participants who have received the tumor genetic pre-test counseling tool who undergo TGT by chart review (Stage 2)
Time Frame: Up to 90 days
A medical record review of TGT completion date will be conducted. If TGT was not completed, the study staff will review and record reasons for non-completion, and date of last follow-up.
Up to 90 days
