NCT ID: NCT01986790

Last Updated: 2016-06-09

Results Overview

Knowledge measures the degree at which participants understand the details about health insurance plans. Knowledge was scored on a scale from 0 to 7 based on number of correct answers to the 7 items. A higher value is considered to be a better outcome. Bivariate outcome data can be found below.

Measure
Plain Language
This intervention group will receive a plain-language table describing the features and costs of health insurance plans, with definitions of health insurance terms incorporated into the table. Plain Language
Plain Language + Visuals
This intervention group will receive the plain-language table plus visuals that focus on specific features of the plans. Participants will be able to view the information about each health insurance feature one feature at a time, in the order they prefer. Plain Language + Visuals
Plain Language + Narratives
This intervention group will receive the plain language table plus narratives about how others might use and rate the insurance plans. Plain Language + Narratives

Timeframe: 1 day (Immediately following showing the participant the assigned intervention (plain language table, plain language table + visuals, or plain language table + narratives)

Population: Analysis is represented as mean (standard deviation) of calculated knowledge.

Knowledge measures the degree at which participants understand the details about health insurance plans. Knowledge was scored on a scale from 0 to 7 based on number of correct answers to the 7 items. A higher value is considered to be a better outcome. Bivariate outcome data can be found below.

PRIMARY outcome

Timeframe: 1 day (Immediately following showing the participant the assigned intervention (plain language table, plain language table + visuals, or plain language table + narratives)

Population: Analysis is represented as mean (standard deviation) of calculated uncertainty.

A survey will be administered in order to measure participants' confidence in the features of health insurance plans that matter most to them and the insurance plan they chose of the ones presented. Confidence in choice is scored on a scale from 0 to 100, with higher scores indicating more decisional conflict/more uncertainty/less confidence in choice. Bivariate outcome data can be found below.

PRIMARY outcome

Timeframe: 1 day (Immediately following showing the participant the assigned intervention (plain language table, plain language table + visuals, or plain language table + narratives)

Population: Analysis is represented as mean (standard deviation) of calculated satisfaction.

A survey will be administered in order to measure the extent to which participants are satisfied with the information presented to them. Satisfaction was scored on a scale from 1 to 4, with higher scores indicating higher levels of satisfaction. Bivariate outcome data can be found below.
