Content analysis is widely used to analyze sexual themes and messages on television. Although researchers generally use a sampling procedure to identify programs for analysis, there is currently no gold standard for the number of episodes needed to establish a valid, representative sample. This study sought to explore how many episodes of weekly television programs should be examined for an accurate assessment of sexual content present throughout the season. Various sampling strategies were used to select episodes from programs that ran in the 1998-1999 season, and results were compared with data collected from all episodes of these programs to test representativeness. Findings suggest that to provide a representative assessment of sexual content on television programs for behavior-level variables, a random sample of five episodes of weekly television programs is sufficient, while three episodes may be acceptable if variation is minimal. A random sample of seven episodes is needed f...

We identify the adolescent and family factors that shape the time adolescents spend viewing television. Adolescent traits, family/household characteristics, television access, and TV viewing time were assessed by self-report using a web-based survey conducted with a sample of 457 14- to 16-year-old adolescents in a Northeastern US city. Bivariate analyses indicated that the number of televisions in the home, having a bedroom TV, and subscribing to premium cable/satellite channels were each positively and significantly associated with television viewing time. Regression results show that having greater access to TV significantly increased viewing independent of adolescent and family variables. In addition, the influence of different forms of access on adolescent time varied by respondent race. Having a television set in the bedroom was the strongest predictor of TV time for White adolescents, and having more television sets in the home was the strongest predictor of TV time for Black...

Intimate partner violence is a significant women's health issue. Since the news media can play a role in policy development, it is important to understand how newspapers have portrayed training and screening. The purpose of this study was to describe the frequency and nature of print news coverage of health issues related to partner violence, specifically, provider training and screening by health providers. We conducted a content analysis on articles obtained from major city and state capital daily newspapers from 20 states. News articles and editorials mentioning intimate partner violence and provider training and screening were examined for the years 1994 through 2001 (N = 188). Results showed that print news coverage was limited and received low levels of attention, indicating little potential to influence either policy or individual behavior. However, when the issue was covered, little debate or controversy was present, and a broad discussion of the issue was generally provided. News coverage of training and screening could be improved by increasing dissemination of research results, illustrating the policy implications of these issues, and offering resource information to women experiencing violence.

Dating violence is highly prevalent among adolescents. Of importance, dating violence has been associated with negative physical and mental health outcomes for teens and high-risk behaviors such as unsafe sex practices. Although a growing body of research has examined the extent and nature of this problem, little research has considered aspects of the media that might be associated with risk for teen dating violence, such as time spent using media and effects of media content. This article provides an overview of the prevalence of teen dating violence, describes the potential for assessing media use as a risk factor, offers a conceptual model, and suggests ideas for future research.

Childhood obesity is a growing problem in the USA. As parents play a major role in shaping a child's diet, the present study examines food advertisements (ads) directed towards parents in parenting and family magazines. Given the potential for magazines to influence attitudes and knowledge, we used content analysis to examine the food ads appearing in four issues each of six different parenting and family magazines from 2008 (n 24). USA. Food ads in parenting and family magazines. We identified 476 food ads, which represented approximately 32 % of all ads in the magazine sample. Snack foods (13 %) were the most frequently observed food ads, followed by dairy products (7 %). The most frequently used sales theme was ‘taste’ (55 %). Some ads promoted foods as ‘healthy’ (14 %) and some made specific health claims (18 %), such as asserting the product would help lower cholesterol. In addition to taste and health and nutrition appeals, we found several themes used in ad messages to promote products, including the following: ‘convenience’, ‘economical’, ‘fun’ and ‘helping families spend time together’. We also found that over half (n 405, 55·9 %) of products (n 725) advertised were products of poor nutritional quality based on total fat, saturated fat, sodium, protein, sugar and fibre contents, and that ads for such products were slightly more likely to use certain sales themes like ‘fun’ (P = 0·04) and ‘no guilt’ (P = 0·03). Interventions should be developed to help parents understand nutritional information seen in food ads and to learn how various foods contribute to providing a balanced family diet.

Numeracy, or, "the ability to use and understand numbers in daily life" is a critical component of health literacy. However, little research has focused on numeracy in young adults (ages 18-29). We used a national sample to examine how health-information seeking, trust in sources, and interactions with health care providers differ for young adults with lower and higher numeracy. We included respondents ages 18 to 29 (n = 661) from the latest administration (2008) of the Health Information National Trends Survey (HINTS). There were no significant differences between those with lower and higher numeracy for most sociodemographic variables, nor did numeracy predict trust in health information sources. However, there were several differences for health-information seeking and health-provider interactions. Those with lower numeracy were significantly more likely to say their most recent search took a lot of effort (46% vs. 24%, p = .0008) and was frustrating (45% vs. 22%, p = .0038). Those in the lower numeracy group also reported more negative interactions with health providers, including feeling less able to rely on their provider (62% vs. 86%, p < .0001), and less likely to say their provider made sure they understood information (70% vs. 88%, p = .0001) and helped with any uncertainty (51% vs. 75%, p < .0001), even when adjusting for other variables. Our data suggest that limited comfort with numbers and statistics can influence a variety of health-related factors for young adults. More research is needed to understand how health literacy skills--including numeracy--influence health-information seeking, patient-provider relationships, and health outcomes, for young adults.

Content analysis is a research method that was traditionally utilized by communication scholars, but as the study of media messages has grown, scholars in other fields have increasingly relied on the methodology. This paper reports on a systematic review of studies using quantitative content analysis methods to examine health messages in the mass media, excluding the Internet, from 1985 to 2005. We searched for health-related content analysis studies published in peer-reviewed journals, identifying 441 articles meeting inclusion criteria. We examined article attributes including theories used, topics, media type, and intercoder reliability measures, and looked at differences over time. Our findings show that studies focusing on health-related messages increased from 1985 to 2005. During this time, studies primarily examined magazines, television, and newspapers, with an emphasis on topics related to substance use, violence, sex, and obesity and body image. Results suggest that studies published in communication journals are significantly more likely to include intercoder reliability data and theory discussion. We recommend that all publications, regardless of discipline or impact factor, request the inclusion of intercoder reliability data reported for individual variables, and suggest that authors address theoretical concepts when appropriate. We also encourage authors to include the term "content analysis," as well as media type and health topic studied, as keywords to make it easier to locate articles of interest when conducting literature searches.
