Information seeking from media and family/friends increases the likelihood of engaging in healthy lifestyle behaviors

The amount of cancer-related information available to the general population continues to grow; yet, its effects are unclear. This study extends previous cross-sectional research establishing that cancer information seeking across a variety of sources is extensive and positively associated with engaging in health-related behaviors. The authors studied how active information seeking about cancer prevention influenced three healthy lifestyle behaviors using a 2-round nationally representative sample of adults ages 40–70 years (n = 1,795), using propensity scoring to control for potential confounders including baseline behavior. The adjusted odds of dieting at follow-up were 1.51 (95% CI: 1.05, 2.19) times higher for those who reported baseline seeking from media and interpersonal sources relative to nonseekers. Baseline seekers ate 0.59 (95% CI: 0.28, 0.91) more fruits and vegetable servings per day and exercised 0.36 (95% CI: 0.12, 0.60) more days per week at 1-year follow-up compared with nonseekers. The effects of seeking from media and friends/family on eating fruits and vegetables and exercising were independent of seeking from physicians. The authors offer several explanations for why information seeking predicts healthy lifestyle behaviors: information obtained motivates these behaviors; information sought teaches specific techniques; and the act of information seeking may reinforce a psychological commitment to dieting, eating fruits and vegetables, and exercising.

Is cannabis an illicit drug or a medicine? A quantitative framing analysis of Israeli newspaper coverage.

BACKGROUND Various countries and states, including Israel, have recently legalized cannabis for therapeutic purposes (CTP). These changes have received mass media coverage and prompted national and international dialogue about the status of cannabis and whether or not it can be defined as a (legitimate) medicine, illicit and harmful drug, or both. News media framing may influence, and be influenced by, public opinion regarding CTP and support for CTP license provisions for patients. This study examines the framing of CTP in Israeli media coverage and the association between media coverage and trends in the provision of CTP licenses in Israel over time. METHODS All published news articles relevant to CTP and the framing of cannabis (N=214) from the three highest circulation newspapers in Israel were content analyzed. Articles were published between January 2007 and June 2013, a period in which CTP licenses granted by the Ministry of Health increased substantially. RESULTS In the majority of CTP news articles (69%), cannabis was framed as a medicine, although in almost one third of articles (31%) cannabis was framed as an illicit drug. The relative proportion of news items in which cannabis was framed as an illicit drug fluctuated during the study period, but was unrelated to linear or curvilinear trends in CTP licensing. CONCLUSION The relatively large proportion of news items framing cannabis as a medicine is consistent with growing support for the expansion of the Israels CTP program.

The role of direct-to-consumer advertising in shaping public opinion surrounding prescription drug use to treat depression or anxiety in youth.

This study investigated the impact of exposure to prescription drug advertisements for antidepressants and antianxiety medications on public opinion regarding preferred treatment options for youth suffering from depression or anxiety. The study randomly recruited a nationally representative adult sample (N = 402) through the 2007 Annenberg National Health Communication Survey. The study examined the distribution of public support for the use of antidepressant drugs to treat depression and anxiety disorders in youth. The analysis adjusted for the effects of demographic characteristics, prior knowledge about prescription drugs, and personal and familial drug history. Attitude toward direct-to-consumer advertising (DTCA, for all products) moderated the effect of exposure to ads for these drug treatments on support for their use among youth as a preferred treatment. Among respondents with negative attitude toward direct-to-consumer advertising (for all products), with increased exposure to ads for antidepressants and antianxiety medications, support for the use of these drugs to treat youth decreased. Among this group, with high levels of exposure to advertisements, the predicted probability of support decreased from 0.68 (95% CI: 0.61 to 0.76) to 0.46 (95% CI: 0.38 to 0.56). No effect was found among respondents with positive attitudes toward DTCA (for all products). The implications of the findings are discussed.

Nonmedical information seeking amid conflicting health information: negative and positive effects on prostate cancer screening

Abstract This study investigates the impact of seeking information about the prostate-specific antigen (PSA) test on men’s PSA test use during a period of conflicting recommendations. Analyses used longitudinal survey data collected in 2005 and 2006 from a nationally representative sample of U.S. males aged 40–70 years (n = 777). Cross-sectionally, nonmedical information seeking was significantly associated with increased odds of having a PSA test in the past year (Time 1 odds ratio [OR] = 9.74, p < .01, 95% confidence interval [CI] = 4.37, 21.70; Time 2 OR = 5.78, p < .01, 95% CI = 3.17, 10.55). However, lagged analyses showed that among men who had a PSA at Time 1, active seeking is associated with reduced odds of later having a PSA test (OR = 0.33, p < .05, 95% CI = 0.13, 0.85). Participants who had not had a PSA test in the past year very rarely sought information about PSA tests. Information acquisition in an environment of conflicting recommendations may influence adoption of cancer screening behaviors.

Medical Cannabis A Framing Analysis of Israeli Newspaper Coverage

Medical cannabis is a topic of increasing debate. To investigate this issue, we conducted a content analysis of Israeli news coverage of medical cannabis from 2007 to 2013. A deductive framing analysis examined three elite issue frames—medical, policy, and law enforcement. Additionally, inductive analysis revealed a a fourth, nonelite patients’ frame. Each frame was associated with a distinct pattern of textual elements, including portrayal of patients, references to cannabis, opinion about medical cannabis, and salience of scientific research. The most common and most stable frame was the policy frame. Implications for framing theory are discussed.

Does the Number of Cancer Patients' Close Social Ties Affect Cancer-Related Information Seeking Through Communication Efficacy? Testing a Mediation Model

This study addresses whether having a broad social network of close friends equips cancer patients with increased efficacy to engage in communication about their cancer, which then leads to an increased likelihood of patients actively seeking cancer-related information. Guided by the theory of motivated information management, the study also tests whether the effect of the number of close social ties on information seeking is mediated, in part, by communication efficacy. Results are based on data collected from a randomly drawn sample from the Pennsylvania Cancer Registry of 2,013 cancer patients who completed mail surveys in the Fall of 2006. Results are consistent with a cross-sectional mediation effect in which the number of close social ties in ones social network is positively associated with communication efficacy (b = .17, p = .001), which, in turn, is positively associated with cancer-related information seeking (b = .13, p < .001).

Examining Patterns and Motivations for Drug-Related Information Seeking and Scanning Behavior: A Cross-National Comparison of American and Israeli College Students

The current study uses a grounded theory approach to explore dimensions and bi-national comparisons of active information seeking efforts (seeking) for and passive information acquisition (scanning) of drug-related information among two college student samples from the United States (N = 25) and Israel (N = 39). Specifically, the study focuses on seeking and scanning related to amphetamines and marijuana, two frequently used drugs among college populations, about which information is easily accessible. Results of semi-structured interviews suggest that information scanning and seeking about marijuana and amphetamines are common, particularly from peers and from the Internet. The analysis uncovers themes relating to young adults’ drug-related, information-seeking behaviors, including cross-source information acquisition across interpersonal and media sources, and motivations for engaging in active efforts to seek drug-related information. These findings extend research on information seeking and scanning and suggest future research should examine predictors and effects of these behaviors in the context of substance use.

Examining effects of medical cannabis narratives on beliefs, attitudes, and intentions related to recreational cannabis: A web-based randomized experiment

BACKGROUND This experimental study tests effects of exposure to video narratives about successful symptom relief with Medical Cannabis (MC) on attitudes, beliefs, and intentions related to recreational cannabis use. METHODS Patient video testimonials were modeled after those found in extant media coverage. Israeli participants (N = 396) recruited through an online survey company were randomly assigned to view a narrative or a non-narrative video containing equivalent information about MC. Video content was further manipulated based on whether the protagonist had a stigmatized disease or not, and whether attribution of responsibility for his disease was internal or external. RESULTS Exposure to patient testimonials indirectly increased positive attitudes, beliefs and intentions related to recreational cannabis use through changing attitudes, beliefs and intentions related to MC. Furthermore, exposure to narratives in which the patient was presented as not to blame for contracting his illness (external attribution) was associated with more positive attitudes, beliefs and intentions toward MC, a factor that was significantly associated with more positive attitudes, beliefs and intentions related to recreational cannabis use. CONCLUSIONS These results suggest that narrative news media coverage of MC may influence public attitudes toward recreational cannabis. Because such media stories continue to be commonplace, it is important to examine potential spillover effects of this coverage on public perceptions of recreational cannabis. Cannabis prevention programs should address the role of media coverage in shaping public opinion and address the distinction between medical and recreational cannabis use.

A Cross-Comparative Survey of Information Seeking and Scanning About Drug-Related Sources and Topics Among U.S. and Israeli College Students

Abstract There is an increasing amount of drug-related information that is easily accessible from media and interpersonal sources. Recent research shows significant positive associations between information acquisition and nonmedical drug use intentions among college students. This study examines information about amphetamines and marijuana that was actively searched (“seeking”) as well as information that was encountered during routine media use (“scanning”). Data are drawn from a cross-national comparative survey of college students in the United States (N = 734) and in Israel (N = 800). U.S. participants reported seeking and scanning information about marijuana across a broader range of sources than Israeli participants. Among U.S. and Israeli participants, the most frequently searched marijuana-related topics included the benefits of marijuana, negative effects of marijuana use, and political reasons why marijuana should be legal. Participants from both countries reported the benefits of amphetamines, and the negative effects of amphetamine use as the most frequently searched topics about amphetamines. Participants in both countries identified the internet and friends as the most popular sources of drug-related information and noted that physicians, friends, and the internet were the most trusted sources. Implications for research on information seeking and health communication are discussed.

Measures of Information Seeking: A Validation Study in the Context of Nonmedical Drug Use Behaviors

ABSTRACT Health information is readily available and easily obtained from a variety of media and interpersonal sources. Although several studies have examined health-related information seeking, a comprehensive validation study of this measure is still needed. This study uses a longitudinal cohort study of Israeli university students (N = 800) aged 18–30, and a cross-sectional sample of U.S. college students (N = 498) to validate measures of information seeking about the nonmedical use of two drugs (marijuana and amphetamines) from a range of media and interpersonal sources. Information seeking measures for both drug types showed good convergent, discriminant, nomological, and test-retest validity. Results offer support for the use of these measures as valid indicators of the constructs for which they were designed. Implications for the use of these measures in future research are discussed.
