Medication Adherence
• Placebo-controlled Trial of Bupropion for Smoking Cessation in Pregnant Women • Daily text messages
– Intro: Baby Development Messages – Ending: Reminder to take study medication – Assessment: Respond when medication taken
• Had to revise protocol to include handing out cellphones – Participant service cancellation – Mobility of population –lack of “place of
residence”

Twitter Language Predicts Excessive Drinking (County Level)
• Behavioral Risk Factor Surveillance System data (2006-2012) • 50 states, plus DC, Puerto Rico, Guam and US Virgin
Islands • Excessive drinking
– Binge (drinking 5 or more drinks on an occasion for men or 4 or more drinks on an occasion for women)
– Heavy Drinking (15 or more drinks per week for men or 8 or more drinks per week for women)
![Page 16: Digital Platforms and Substance Use Research · Digital Platforms and Substance Use Research April 17, 2017 Brenda Curtis, PhD, MSPH Assistant Professor Department of Psychiatry—Addictions](https://reader033.fdocuments.net/reader033/viewer/2022060610/606157eaafc219780d63639f/html5/thumbnails/16.jpg)

• A random 10% of Twitter data was collected between October 2011 and December 2013, totaling 2.24 billion tweets.
• Used geolocation information to “map” 22% of these tweets across 3,146 counties.
• Limited the analysis to counties for which at least 30,000 words were available to insure an adequate sample of a county’s language, reduced this number to 1,667 counties.
• For each of the 1,667 counties, scores for the 2000 pre-specified topics formed the independent variables in our statistical analysis.

Can we predict Excess Drinking from language?
• Using a 10 fold, cross validated ridge regression, we predicted excess drinking from • Twitter language alone • Demographic and SES variables alone • Twitter, demographics and SES combined
![Page 18: Digital Platforms and Substance Use Research · Digital Platforms and Substance Use Research April 17, 2017 Brenda Curtis, PhD, MSPH Assistant Professor Department of Psychiatry—Addictions](https://reader033.fdocuments.net/reader033/viewer/2022060610/606157eaafc219780d63639f/html5/thumbnails/18.jpg)

Note: For ease of inspection, correlations are color formatted, ranging from strongly positive (dark green) to strongly negative (dark red). Cells in white are not significant, all other correlations significant at a Benjamini–Hochberg corrected significance level of p < 5x10-4.
Correlations between excessive drinking and standard demographic and socio-economic variables

Topics correlated with excessive drinking
r = 0.32 r = 0.32 r = 0.30 r = 0.30 r = 0.29
r = -0.44 r = -0.41 r = -0.40 r = -0.39 r = -0.38
Note: Topics in teal are positively correlated with excess drinking, while topics in blue are negatively correlated. The size of the word represents its relative frequency within the topic. Larger words are more frequent, while smaller words are less frequent. All correlations significant at a Benjamini–Hochberg corrected significance level of p < 1x10-6.

Study Design
• Participants are asked to: • complete an intake battery • report weekly on their AOD via an online survey • give permission to extract treatment entry, discharge, and
urinalysis data from their clinic record • give permission to extract data from their Facebook and/or
Twitter accounts
• Monitoring participants for 26 weeks post-baseline

Specific Aims
1) Analyze differences in the frequency and content of dialogue on social media to determine the words or phrases associated with time of relapse and treatment drop out; as well as drug use, treatment status, duration, and discharge status.

27
Specific Aims
2) Describe the frequency and patterns of dialogue on social media with respect to six content areas: a) drug information, b) drug use, c) treatment information, d) risk and protective factors for drug use (e.g., stress levels, depression), e) drug use consequences and; f) communications promoting use of AOD.

28
Specific Aims
3) Determine a) the prevalence and frequency of Facebook, Twitter, and other social media platform use by patients in substance abuse treatment; b) patients’ receptiveness to the use of these platforms for interventions that promote positive substance abuse treatment outcomes and; c) differences in platform use by geographic area, age, gender, SES, race, and drug use and health profile

What might we learn?
Social media language could provide: • a natural and more continuous method of monitoring
changes in an individual’s engagement within the treatment process
• their stage of change • their risk for treatment drop out and relapse • their intention to attend 12-Step meetings or to
reinitiate drug use • reflect environmental conditions that may support or
detract from recovery, such as personal depression and stress levels, or new pressures from home, friends or work environment
