Overview/Goals of the Study Collect tobacco-related information (attitudes, opinions, and behaviors) from current adult residents of Oswego County to: 1.Develop a greater understanding of current attitudes, opinions, and behaviors regarding tobacco in Oswego County. 2.Use this data to make data-driven decisions in the development and planning of future TFNOC programming and activities. 3.Use current data and past data to identify trends and evaluate impact.

Methodology →Telephone survey, instrument developed by NYSDOH, TFNOC, and JLC. → ≈30 survey questions ( ≈25 tobacco-related, 5 demographics) →Calls made between 3:30-9:00 p.m., M-F, January 2014 →Random residential landline and cellular numbers (≈24%, 20% c-o) →All calls made by JLC employees trained in Human Subject Research laws and effective interviewing techniques, from a call center in Watertown, NY →400 adult participants (18+ years of age) →≈40% response rate → At least 4 call backs to each no answer/busy → Margin of Error: →approximately ±3.9% →Margin of Error is larger than ±3.9% when investigating smaller subgroups (n<400) →Telephone interviewing historically selected as the sampling protocol since it is far less susceptible to bias, and often-times less expensive, than: Mail surveys; Intercept (face-to-face) surveys; Focus groups; or Online surveying Sample Size (n=…) Approximate Margin of Error 30 ±14.3% 50 ±11.1% 75 ±9.0% 100 ±7.8% 125 ±7.0% 150 ±6.4% 175 ±5.9% 200 ±5.5% 225 ±5.2% 250 ±5.0% 275 ±4.7% 300 ±4.5% 325 ±4.3% 350 ±4.2% 375 ±4.0% 400 ±3.9% Margins of Error for Varying Sample Sizes

More Methodology – Error Before we begin the roll-out of highlighted results in 2014, it is predicted that each of you … at various times … for varying survey results ….. during this presentation … will experience … Surprise, and Confirmation, even seemingly obvious confirmation, and Disagreement, and even possibly Disbelief (and, for three of these four reactions, the natural response is for one to question the methodology in the study!)
5
More Methodology – Error There are three, and only three, sources of error when completing research based upon sampling (not exclusive to survey research) RANDOM ERROR chance of sampling (how can n=400, out of N=90,000 in Oswego County, be believed? Sampling -- Coins? Aspirin? Nate Silver …. 1 out of 2,252,000,000,000,000) SAMPLING ERROR the way the sample was selected (under-represented groups …. Quotas vs. Weighting … school employees … cell-only persons … JLC weights by SEX, AGE, ED, HH TYPE, and PHONE OWNERSHIP) NON-SAMPLING ERROR what was actually measured (broken thermometer? … definitions, phrasing, non-leading, consistency, and constant supervision)
6
Final Methodology – Controlling Error Confidence Level and Margin of Error As a result of using n=400, and weighting the data to adjust for sampling error, and using IRB approved valid survey questions with well-trained interviewers -- We are 95% confident that a sampled % that is reported in this study for Oswego County is within approximately ±4% of what would be found if, in fact, all adults in the county were surveyed.

Presentation of Results The interviews included eight sections of tobacco-related survey question, all of course, tied to the TFNOC workplan. Survey Sections: 1.Spreading the Message about the Dangers of Tobacco 2.Tobacco Marketing – Displays in Stores 3.Tobacco Marketing – Advertisements 4.Tobacco Point of Sale 5.Outdoor Tobacco Policies 6.Smoke Free Workplace 7.Smoke Free Housing 8.Tobacco Use

Presentation of Results – Highlight #1 (Table 22, Page 47) What more may we learn from the “not allow at all” statistic (36%)? – “framing” that statistic…
9
Presentation of Results – “Framing a Statistic” With survey-generated data, often times the following five methods are used to better understand the presented statistic – “framing” that statistic: Within Response Distribution (Majority? 4:1?) Trend Across Time (Increased? Decreased?) Compare to Target/Benchmark (compare to current 21-county regional average? Workplan goal?) Ranking among similar variables (First? Last?) Cross-tabulations by Potential Explanatory Variables (Smokers and Non-smokers differ? Age-dependent? Gender- dependent?)
