Determining an Appropriate Sample Size for Qualitative Interviews to Achieve True and Near Code Saturation: Secondary Analysis of Data.

Background: In-depth interviews are a common method of qualitative data collection, providing rich data on individuals' perceptions and behaviors that would be challenging to collect with quantitative methods. Researchers typically need to decide on sample size a priori. Although studies have assessed when saturation has been achieved, there is no agreement on the minimum number of interviews needed to achieve saturation.

Understanding US Physician and Pharmacist Attitudes Toward Biosimilar Products: A Qualitative Study.

Background: Biosimilars account for 30-40% of biologic medications dispensed in the United States (US), yet healthcare providers in relevant medical specialties have limited awareness of biosimilars and their characteristics. Likewise, many providers perceive biosimilars as less safe and effective than original biologics and are more comfortable prescribing original biologics to patients.

Methods: We conducted in-person focus groups at three clinical sites in California and Texas (n = 49) to explore the reasons behind US healthcare providers' limited understanding of, cautious attitudes toward, and reluctance to prescribe biosimilars.

Air Aware: Improving Use of an Existing Air Quality and Health Tool.

Exposure to air pollutants is a significant health risk for individuals with asthma, cardiovascular disease, and chronic obstructive pulmonary disease. Measures such as limiting time outdoors or performing less strenuous tasks when air quality levels are better can mitigate these risks, but only if people are aware of both these recommendations and how to know when air quality is best, and worst. Formative audience assessment determined that applications developed for mobile devices are the optimal way to provide this information, but knowledge of the existing United States Environmental Protection Agency (EPA) and partners' AirNow tool was minimal.

Examining Information Needs of Heart Failure Patients and Family Companions Using a Previsit Question Prompt List and Audiotaped Data: Findings From a Pilot Study.

Background: Question prompt lists (QPLs) are an effective tool for improving communication during medical visits. However, no studies have attempted to correlate intentions related to question asking and actual questions asked during visits. Moreover, few studies have used QPLs with patients with heart failure (HF) or family companions who accompany them to visits.

Visual images of prescription drug benefits in direct-to-consumer television advertisements.

Objective: Images demonstrating a prescription drug's efficacy are often included in direct-to-consumer television advertisements. The current research assessed whether exaggerated efficacy images can mislead individuals, and whether providing accurate quantitative information can reduce these misperceptions.

Methods: We conducted two experimental studies with internet panelists 60 years and older testing drug efficacy images in television ads for wet age-related macular degeneration (N = 901) and plaque psoriasis (N = 902).

Development and validation of prescription drug risk, efficacy, and benefit perception measures in the context of direct-to-consumer prescription drug advertising.

Purpose: Understanding patient perceptions of prescription drug risks and benefits is an important component of determining risk-benefit tradeoffs and helping patients make informed medication decisions. However, few validated measures exist for capturing such perceptions. The purpose of this study was to develop and validate measures of perception of prescription drug risk, efficacy, and benefit.

The Effect of Including Quantitative Information on Multiple Endpoints in Direct-to-Consumer Prescription Drug Television Advertisements.

Previous research found that adding a single piece of quantitative information about prescription drug benefits to direct-to-consumer (DTC) ads helps consumers understand how well the drug works. However, drug information often includes quantitative information on multiple benefit outcomes and risks. Thus, we examined whether consumer understanding was similarly improved when DTC television ads include varying amounts of quantitative information.

Actors in whitespace: Communicating risk information on pharmaceutical websites.

This study examined the use of an actor to communicate prescription drug risks on pharmaceutical websites. Participants viewed risk information for a fictitious drug in one of several static visual formats or as a paragraph plus an animated actor; and with or without a signal directing them to the risk information text. The signal had little effect on outcomes.

Testimonials and Informational Videos on Branded Prescription Drug Websites: Experimental Study to Assess Influence on Consumer Knowledge and Perceptions.

Background: Direct-to-consumer (DTC) promotion of prescription drugs can affect consumer behaviors and health outcomes, and Internet drug promotion is growing rapidly. Branded drug websites often capitalize on the multimedia capabilities of the Internet by using videos to emphasize drug benefits and characteristics. However, it is unknown how such videos affect consumer processing of drug information.

Virtual Versus In-Person Focus Groups: Comparison of Costs, Recruitment, and Participant Logistics.

Background: Virtual focus groups-such as online chat and video groups-are increasingly promoted as qualitative research tools. Theoretically, virtual groups offer several advantages, including lower cost, faster recruitment, greater geographic diversity, enrollment of hard-to-reach populations, and reduced participant burden. However, no study has compared virtual and in-person focus groups on these metrics.

Placement and Format of Risk Information on Direct-to-Consumer Prescription Drug Websites.

We investigated whether the location and format of risk information on branded prescription drug websites influence consumers' knowledge and perceptions of the drug's risks. Participants (Internet panelists with high cholesterol [n = 2,609] or seasonal allergies [n = 2,637]) were randomly assigned to view a website promoting a fictitious prescription drug for their condition. The website presented risk information at the bottom of the homepage, or at the bottom of the homepage with a signal above indicating that the risk information was located below, or on a linked secondary page.

Consumer confusion between prescription drug precautions and side effects.

Objective: Multiple studies have identified consumers' difficulty correctly interpreting risk information provided about prescription drugs, whether in printed format or online. This study's purpose was to explore whether consumers can distinguish between prescription drug precautions and side effects presented on brand-name drug websites.

Methods: Participants (n=873) viewed fictitious drug websites that presented both precautions and side effects for one of four drugs, and they completed a survey assessing recall and comprehension.

Peer-Generated Health Information: The Role of Online Communities in Patient and Caregiver Health Decisions.

Individuals increasingly access peer-generated health information (PGHI) through social media, especially online health communities (OHCs). Previous research has documented PGHI topics, credibility assessment strategies, and PGHI's connection with well-being. However, there is limited evidence on where, when, and why individuals seek PGHI and how they use PGHI in health decisions.

Are Disease Awareness Links on Prescription Drug Websites Misleading? A Randomized Study.

We sought to determine whether links from branded prescription drug websites to websites containing disease information mislead participants about drug benefits and whether nonsponsorship disclosures diminish this potential effect. We randomly assigned online panelists with depression (N = 1,071) to view a fictitious prescription drug website that had (a) no link to a disease information website (control), (b) a link with no disclosure, (c) a link with a simple nonsponsorship disclosure, or (d) a link with a detailed nonsponsorship disclosure. If participants in the link conditions did not click the link, they were returned to the drug website and encouraged to click it.

Correction of misleading information in prescription drug television advertising: The roles of advertisement similarity and time delay.

Background: Prescription drug television advertisements containing potentially consequential misinformation sometimes appear in the United States. When that happens, the U.S.

Future Challenges and Opportunities in Online Prescription Drug Promotion Research Comment on "Trouble Spots in Online Direct-to-Consumer Prescription Drug Promotion: A Content Analysis of FDA Warning Letters".

Despite increased availability of online promotional tools for prescription drug marketers, evidence on online prescription drug promotion is far from settled or conclusive. We highlight ways in which online prescription drug promotion is similar to conventional broadcast and print advertising and ways in which it differs. We also highlight five key areas for future research: branded drug website influence on consumer knowledge and behavior, interactive features on branded drug websites, mobile viewing of branded websites and mobile advertisements, online promotion and non-US audiences, and social media and medication decisions.

Visual presentations of efficacy data in direct-to-consumer prescription drug print and television advertisements: A randomized study.

Objective: To determine whether visual aids help people recall quantitative efficacy information in direct-to-consumer (DTC) prescription drug advertisements, and if so, which types of visual aids are most helpful.

Methods: Individuals diagnosed with high cholesterol (n=2504) were randomized to view a fictional DTC print or television advertisement with no visual aid or one of four visual aids (pie chart, bar chart, table, or pictograph) depicting drug efficacy. We measured drug efficacy and risk recall, drug perceptions and attitudes, and behavioral intentions.

Perceived healthcare provider reactions to patient and caregiver use of online health communities.

Objective: Many Internet users seek health information through online health communities (OHCs) and other social media. Yet few studies assess how individuals use peer-generated health information, and many healthcare providers (HCPs) believe OHCs interfere with patient-provider relationships. This study explored how individuals use OHC content in clinical discussions and how HCPs react to it.

Presenting efficacy information in direct-to-consumer prescription drug advertisements.

Objective: We evaluated whether presenting prescription drug efficacy information in direct-to-consumer (DTC) advertising helps individuals accurately report a drug's benefits and, if so, which numerical format is most helpful.

Methods: We conducted a randomized, controlled study of individuals diagnosed with high cholesterol (n=2807) who viewed fictitious prescription drug print or television ads containing either no drug efficacy information or efficacy information in one of five numerical formats. We measured drug efficacy recall, drug perceptions and attitudes, behavioral intentions, and drug risk recall.

Communicating risk of hereditary breast and ovarian cancer with an interactive decision support tool.

Objective: Women with hereditary breast and ovarian cancer syndrome (HBOC) face a higher risk of earlier, more aggressive cancer. Because of HBOC's rarity, screening is recommended only for women with strong cancer family histories. However, most patients do not have accurate history available and struggle to understand genetic concepts.

Storm-Related Carbon Monoxide Poisoning: An Investigation of Target Audience Knowledge and Risk Behaviors.

Carbon monoxide (CO) poisonings in the United States consistently occur when residents improperly use portable gasoline-powered generators and other tools following severe storms and power outages. However, protective behaviors-such as installing CO alarms and placing generators more than 20 feet away from indoor structures-can prevent these poisonings. This study identified knowledge, attitudes, and beliefs that lead consumers to adopt risk and protective behaviors for storm-related CO poisoning and post-storm generator use.

Risk and protective behaviours for residential carbon monoxide poisoning.

Background: Unintentional, non-fire-related carbon monoxide (CO) poisoning is a leading cause of poisoning death and injury in the USA. Residential poisonings caused by faulty furnaces are the most common type of CO exposure. However, these poisonings are largely preventable with annual furnace inspections and CO alarm installation.

Effectiveness of a mass media campaign in promoting HIV testing information seeking among African American women.

"Take Charge. Take the Test." (TCTT), a media campaign promoting HIV testing among African American women, was piloted in Cleveland and Philadelphia from October 2006 to October 2007.
