A Video Intervention to Decrease Patient Fear of Colonoscopy After a Positive Fecal Immunochemical Test

Feasibility as measured by study accrual

Feasibility will be measured by recruitment as the proportion of invited participants who consent and complete the pilot study.

Time frame: Up to 12 months post-abnormal fecal immunochemical test (FIT) result

Feasibility: number of contacts needed to reach target enrollment

Feasibility will be measured by recruitment as the number of contacts required to reach target enrollment.

Time frame: Up to 12 months post-abnormal FIT result

Feasibility: time to reach recruitment

Feasibility will be measured by recruitment as the time required to reach target enrollment. Time to reach recruitment target will be measured in days and described using medians and interquartile range (IQR).

Time frame: Up to 12 months post-abnormal FIT result

Acceptability of the video intervention assessed by a survey

Intervention arm patients will complete a post-intervention survey to assess acceptability of the intervention using the Acceptability of Intervention Measure (AIM), a 4-item measure. Items are rated on a 5-point Likert Scale (1, completely disagree; 5, completely agree). Mean scores will be calculated to generate an average AIM score, where higher scores will indicate higher levels of acceptability.

Time frame: Up to 12 months post-abnormal FIT result

Incidence of fear related to colonoscopy

Intervention arm patients will complete a pre- and post-intervention survey that will include questions about fear of colonoscopy. Usual care patients will complete a baseline survey on the same measures. Fear will be assessed using Manne's 6-item fear of colonoscopy scale. Items are rated on a 5-point Likert scale (1, not at all fearful; 5, extremely fearful). Mean scores will be calculated to generate average fear per participant, with higher scores indicating higher levels of fear.

Time frame: Up to 12 months post-abnormal FIT result

Knowledge about colonoscopy

Intervention arm patients will complete a pre- and post-intervention survey that will include questions about knowledge about colon cancer screening. Usual care patients will complete a baseline survey on the same measures. Knowledge will be measured using 8 validated questions. Incorrect answers will be scored as 0 and correct answers scored as 1. Higher scores will indicate higher levels of knowledge.

Time frame: Up to 12 months post-abnormal FIT result

Self-efficacy related to colonoscopy

Intervention arm patients will complete a pre- and post-intervention survey that will include questions about self-efficacy related to a colonoscopy. Usual care patients will complete a baseline survey on the same measures. Self-efficacy will be assessed by adopting an 8-item self-efficacy scale for colonoscopy completion in patients with inflammatory bowel diseases and responses will be recorded on a 5-point scale. Higher scores will indicate higher levels of self-efficacy.

Time frame: Up to 12 months post-abnormal FIT result

Intent to complete a colonoscopy

Intervention arm patients will complete a pre- and post-intervention survey that will include questions about intent to complete a colonoscopy. Usual care patients will complete a baseline survey on the same measures. Intent will be measured using a single validated question on a nominal scale with 5 options. Responses will be dichotomized to affirmative intent (definitely will do, will do) or uncertain intent (don't know, will not do, and definitely will not do).

Time frame: Up to 12 months post-abnormal FIT result
