Audience segmentation Lecture 4 COMT 492/592 Overview Determine target audience Determine what you need to know Audience research Interpreting results Determining the target audience Primary audience: Clients Secondary audience: People who influence your primary audience (peers; social referents) Tertiary audience: Policymakers Media professionals Supervisors, boards of directors Your employees What is a target audience? People whose behavior you wish to affect. Potential customers or consumers considering whether to adopt the “product” you are promoting. People most at risk for the problem you are addressing. Potential segmentation bases A priori Determined in advance (sex, race, age, residential status) Objective (can be observed/measured) Inferred (assessed thru questionnaire) General or behavioral General or behavioral Self-selection bases Segments define themselves thru response to campaign Rarely indicates why response occurred Bases to segment by: Objective general data – often available thru 2ndary data Age Income Sex Residence Race Family size Inferred general: Inferred behavioral: Obj. Behavioral Access to health care Past behaviors Distance to sources Behavior of peer group/village/family Hours watching different media Personality Lifestyle Risk preferences Media preferences Self-confidence Self-efficacy Perceived benefits/costs Stage of behavior change Social norms Perceived risk Perceived severity Audiences not homogenous Even within an audience subgroup, there may be many important differences with respect to the behavior you are promoting. E.g., an STD prevention program won’t use the same appeals for boys and girls, or older and younger teens. Segmenting by demographics (age, sex, education, etc.) may NOT be as important as segmenting by risk-level or personality. E.g., those who know they’re at risk may react differently to those who feel invulnerable. Theory & Method in Segmentation What criteria are properly used to segment an audience or market? Smorgasboard of techniques and strategies Little direction for preferred strategy What’s needed: Identify subgroups that have common similar determinants of behavior in question Slater, M.D. (1996). Theory and Method in Health Audience Segmentation. J of Health Comm, vol. 1: 267-283. Behavior Determinants 1) Identify from research the known determinants of KAP with respect to goal behavior 2) Identify audience segments on basis of distinctive patterns of determinants HOWEVER…How do you identify these patterns? Segmentation Methods VALS – Values and Lifestyles dataset for commercial use more art than science? SES – Crude segmentation by demographics (education, race, income, gender, geography) Easy to measure, but not that informative Many sub-differences w/in demographic groups overlooked Segmentation Methods (cont’d) Psychosocial variables – Self-efficacy; peer support; etc. Harder to measure More informative Can start w/ demographic sub-groups and then further subdivide by psychosocial But…Assumes there are a few key variables Assumes one has correctly identified them May miss subtle distinctions w/in segments Social Science & Typology Segmentation process usually stops there Need for parsimony…the fewest possible variables to explain audience variance Statistical models are cumbersome when overloaded with too many variables Descriptive vs. predictive models To best guide channel selection & intervention design, segments should be predictive of distinctive patterns of media use Define Target Audience, Focus Message & Choose Media Start with audience Define who they are: sociodemographic variables personal identity - what they care about risk level - stage of behavior change Gear message to fit Choose appropriate media Media diets vary by race & gender Not all teenagers tune into the same kind of media Girls prefer softer music and soap operas Boys prefer action flicks and harder, louder music African-Americans and children from singleparent households watch more TV Steele JR, Brown JD. Adolescent room culture: Studying media in the context of everyday life. J Adolesc Hth 1995; 24(5). Media diet varies by personal identity, too Even within race & class categories, teenagers’ media use vary dramatically Teens define themselves by their identities Girls’ sense of selves may be particularly transitory & vulnerable to media influence Pipher M.

Identity associated with behavior Speaking to teen identities may be key to influencing behavior Identity -- a person’s self-perception & tastes in fashion, music & friends -- may determine sexual risk practice Related to subjective beliefs about what’s important Identity attributes may be more amenable to change than basic sociodemographic variables Prochaska J, Redding C, Harlow L, et al.

Adolescent girls can be segmented by identities Categories of girls’ relationship behavior (Thompson, 1995) Shy girls Romantic idealists Hell-raisers Fast-track girls Having the baby How girls use sexual media (Steele & Brown, 1995) Disinterested Intrigued/Conformers Resisters ? ? Segmenting by risk level: Stages of Change Model Behavior change is not a one-step process Different messages are needed for each stage Precontemplation Contemplation Ready for action Action Maintenance Stages of Behavior Change: Operationalization Pre-contemplation: Contemplation: Intends to use condoms from now on Action: Intends to use condoms in next 6 months Ready-for-action: No intention to use condoms Every time condom use for less than 6 months Maintenance: Condoms used every time for at least 6 months Prochaska J, et al.

Segmenting by risk level: Results Campaigns that target audience by risk level are more effective than nontargeted campaigns -- in smoking cessation, exercise adoption, dietary fat reduction & mammography screening Results of a smoking campaign People who progress from one stage to next early in campaign are more likely to ultimately change behavior 3% pre-contemplators quit smoking 7% pre-contemplators who moved to contemplation in 1st month quit smoking 20% contemplators took action 41% contemplators who moved to ready-for-action in 1st month took action Prochaska JO, et al.

Segmenting by risk level: Condom campaign CDC’s Role Model Stories Campaign, San Francisco, 1992-94 to change women’s HIV risk behavior & community norms, using narrative pamphlets Target audience: Welfare mothers ages 17-54 Different stories developed for each risk category Contemplation: Ready-for Action: Kizzy says she’ll “seriously try” to use condoms Mayeisha decides to use condoms with her next man Action: Champagne uses condoms, but not every time Kinght K, et al.

Segmenting by demographics: Project ACTION Social marketing campaign to promote teenage condom use in Portland, Oregon by Population Services International 1992-94 Community mobilization Condom vending machines Peer skill-building workshops Motivational media campaign Evaluation research Project ACTION: Tailoring the message Target audience: Audience segments: At-risk teens ages 12-21 Caucasian boys; Caucasian girls; African-American boys & girls Different PSAs designed to match sexual scripts of each subgroup PSA for girls: romantic flowers PSA for boys: pretty girls PSA for African-Americans: passionate glance PSAs promote condoms in Portland, Oregon 1992-94 Teens who used condoms in last month increased from 32% to 40% Teens who used condoms with casual partners rose from 72% to 90% Teens who planned to discuss condoms with next partners rose from 53% to 80% Blair J.
