Brief Summary

Researchers have linked media messages such as television programs to multiple problematic health behaviors. The narrative style of many television programs-involving a plot, recurrent characters, entertaining situations, and familiar settings-makes them compelling and likely contributes to the powerful influence these programs can have on behavior. However, narrative messages are not frequently utilized for prosocial purposes. In particular, health education embedded in a narrative context has been neither commonly utilized nor carefully evaluated. Using constructs from two complementary theories of health behavior, family physicians in a large metropolitan region have developed a situation comedy entitled "White Coats" that aims to provide quality patient education. The program currently airs on a local public access channel. The objective of this project is to evaluate the effect of one particular episode of "White Coats" on patient beliefs regarding hypertension.

Outcome Measures

Primary Outcomes (5)

• Change in Likert scale agreement with Perceived severity questionnaire statement from immediately pre-intervention to immediately post-intervention and also 2 months post-intervention

  Participants ranked their agreement with the following statement on an 8-point Likert scale: "If you have high blood pressure, controlling your blood pressure is important."

  immediately pre-intervention, immediately post-intervention, and 2 months post-intervention

• Change in Likert scale agreement with Perceived susceptibility questionnaire statement from immediately pre-intervention to immediately post-intervention and also 2 months post-intervention

  Participants ranked their agreement with the following statement on an 8-point Likert scale: "People don't need to worry about having high blood pressure if they don't have any symptoms (like headaches, chest pain, or blurry vision)."

  immediately pre-intervention, immediately post-intervention, and 2 months post-intervention

• Change in Likert scale agreement with Perceived barriers to change questionnaire statement from immediately pre-intervention to immediately post-intervention and also 2 months post-intervention

  Participants ranked their agreement with the following statement on an 8-point Likert scale: "I can find time to exercise."

  immediately pre-intervention, immediately post-intervention, and 2 months post-intervention

• Change in Likert scale agreement with self-efficacy questionnaire statement from immediately pre-intervention to immediately post-intervention and also 2 months post-intervention

  Participants ranked their agreement with the following statement on an 8-point Likert scale: "I can read food labels to look for high salt foods when I buy groceries."

  immediately pre-intervention, immediately post-intervention, and 2 months post-intervention

• Change in Likert scale agreement with Outcome efficacy questionnaire statement from immediately pre-intervention to immediately post-intervention and also 2 months post-intervention

  Participants ranked their agreement with the following statement on an 8-point Likert scale: "If you have high blood pressure and take your medicines, you can lower your chance of having a heart attack."

  immediately pre-intervention, immediately post-intervention, and 2 months post-intervention

Study Arms (2)

Treatment Group

EXPERIMENTAL

This group viewed the intervention video, a 24-minute episode of the sitcom "White Coats," deliberately scripted with the five health behavior theory constructs we are testing.

Other: 24-minute video episode of patient education TV sitcom "White Coats"

Control Group

PLACEBO COMPARATOR

The control group viewed a 25-minute video on an unrelated subject (depression).

Other: Placebo video

Interventions

24-minute video episode of patient education TV sitcom "White Coats" OTHER

The series features a fictional married couple of Family Medicine physicians who work in the same practice, located in our community. In both their professional and private lives and, in moments both humorous and serious, these doctors teach patients about a wide variety of health topics. The intervention episode addressing hypertension will focus on three different patient-physician plot lines, which were developed to specifically address each of the beliefs about hypertension highlighted in the theoretical model (susceptibility, seriousness, barriers, self-efficacy and outcome efficacy.).

Treatment Group

Placebo video OTHER

The control group watched a 25-minute patient education video on depression.
