Fundamentals of happy ending
Fundamentals of Happy Ending

  • Fully automated smoking cessation intervention

  • Internet & cell-phone

  • Target group: smokers motivated to quit

  • Core idea: The quitter needs different help at different times

    • tunnelling


Three distinct phases
Three distinct phases

  • Three distinct phases

2 weeks + 4 weeks + 11 months

The information architecture of HE

  • This figure shows a sample week from each phase, where each cell represents a unique contact point between client and program that particular day


The information architecture of he1
The information architecture of HE

  • A new unique web-page (□)

  • Each day, week 1 through week 6

  • Todays assignment – interactive diary


The information architecture of he2
The information architecture of HE

Legend:

─ one text-message (SMS) a day

= two text-messages a day

≡ three text-messages a day


The information architecture of he3

“today, your blood pressure has been reduced to that of a non-smoker.”

The information architecture of HE

  • Motivational conflict:

    • short-term positive consequences of starting to smoke again - inflated

    • value of the long term positive consequences of abstinence - deflated

  • Psycho-educative approach

  • Quitting-chronology requires tunnelling


The information architecture of he4
The information architecture of HE non-smoker.”

Choices: (1) reduce stress; (2) regulate

negative affect; or (3) fuel motivation

Available 24 hours a day for one year

No human contact – pre-recorded messages only

  • Data collection: web based surveys

    • Initiating mail + 2 reminders

    • then telephone interview with non-responders

Arguments for tunnelling
Arguments for tunnelling non-smoker.”

  • Required by the therapeutical model

    • tunnelling affords a relationship to the user

    • relationship is a possibility condition for dialog and therapy

  • Different help at different times

    • because the psychological processes are different

  • Keep up the interest


Implication summary
Implication – summary non-smoker.”

  • Automatization + flexibility = success

  • Automatization of interventions

    • stick to it!

    • to preserve the high-reach-low-cost feature of mass media

  • Exploit the flexibility!

    • flexibility is the key to efficacy

  • Learn from clinical psychology

    • take advantage of the therapeutical processes we know from clinical psychology

    • from sequencing and selection towards dialog and relation

    • do not forget sequencing strategies (like tunnelling) on the way


Questions
Questions non-smoker.”

  • Intervention / RCT-results / implications of advances in IT

  • Other dimensions of flexibility?

  • The role of chat rooms and discussion forums for e-health interventions?

    • some of you may be more optimistic than I am...


Nicotine replacement therapy nrt

Trial 1 non-smoker.”

Nicotine Replacement Therapy (NRT)

  • Proportion of NRT users:

    • 93% in treatment vs. 87% in control (N.S.)

  • Higher NRT-adherence in treatment:

    • Days/week of NRT use, mean: 4.5 vs. 3.6; SD = 2.9; t(382) = 3.11, p = .002

    • Weeks of use, mean: 8.3 vs. 7.0; SD = 4.9; t(316) = 2.22, p = .03

  • NRT-adherence did NOT mediate 1yr. sustained abstinence!


Program adherence and abstinence
Program adherence and abstinence non-smoker.”

  • 65% ADHERENCE

  • Adherence to various components are highly correlated. Using a backward conditional procedure, answering the log-off call, came out as the only significant predictor – adding the other variables did not increase explained variance.

  • When tested alone, however, log-on and reading web-pages did also sig. predict abstinence (helpline-calls did not).

    Adherence – each component tested alone:

  • log-off: R² = 25%

  • log-on: R² = 16%

  • web-pages: R² = 8%

  • help-line: N.S.
