Define the goals of your data collection session.
What do you want to find out? These goals should be based on your project goals.

Enhance the user guidance and support features of the „Smoke free“ app by integrating the next features:
– a short guide of using the app
– daily tracking with motivation section, and advice

Therefore we want to find out more about our target group. For example what are their reasons for quiting, if they quit smoking before and why they went back to smoking. Furthermore we want to find out if they know about apps that support you or if they already tried them.

Based on your goal, derive the stakeholders you want to collect data from.
What are your stakeholders? Whom do you need to approach (i.e., who is indispensable for your achieving project goals)?

Our main target group are people who want to quit smoking, but it would also be interessting to talk to people who quit before (successfully or not) to see patterns that helped them or reasons why they were unsuccessfull.

Start with collecting information without approaching your stakeholders (so-called secondary data collection). Use existing websites, app information, and experience the app by yourself. Describe the app you are using in detail (who has developed the app, why, what functionality is available, how can people access the app, etc.)

Prepare an interview study with your primary stakeholders.
Name the stakeholders and explain, why they need to be interviewed. Explain, how you want to contact them.

Our main stakeholders are current smokers and smokers that want to quit. They need to be interviewed because we need to understand the reasoning for quitting and failed quitting attemps so we can fill the gap with the app. Furthermore we need to see if they see an app as a possible support of their quitting journe. Also we need to see if our stakeholder group is correct or if we need to talk to a other subgroup (e.g. longterm smokers or smokers in a certain age)

Justify the type of interview (structured, unstructured, semi-structured).

In our case, a semi-structured interview is the best choice as it allows us to get some general info about person’s smoking routine as well as to focus on each person’s case individually.

Prepare the introduction and the closing session as well as the consent form as well as the questions (the interview should be 20 to 30 min long)
Describe how you plan to conduct the interview (Who is taking notes? How do you take notes? Who is asking questions?)

Einleitung:

Guten Tag Herr/Frau XY,

herzlich Willkommen und vielen Dank, dass sie sich die Zeit für dieses Interview nehmen. Wir sind … und möchten dieses Interview für unseren Unikurs „Human-Computer Interaction“ an der Freien Universität Berlin führen. Im Kurs beschäftigen wir uns mit Digitalen Gesundheitsanwendungen, so genannten DIGAs. Die DiGA, die wir untersuchen möchten ist eine App zur Unterstützung der Rauchentwöhnung und daher möchten wir ihnen einige Fragen zu den Themen Rauchen und Rauchentwöhnung stellen. Damit wir die Daten aus diesem Interview auch verwenden dürfen, brauchen wir bitte die unterschriebene EInverständniserklärung. Außerdem möchten wir das Gespräch, das ca. 20 bis 30 Minuten in Anspruch nehmen wird, gerne aufzeichnen. Ist das für Sie in Ordnung?

Einverständniserklärung

Demographische Fragen:

• Wie viel rauchen Sie pro Tag/pro Woche/pro Monat?
• Welche Tabakprodukte konsumieren Sie?

• Haben Sie schon einmal mit dem Rauchen aufgehört oder versucht mit dem Rauchen aufzuhören?
  • Wenn ja: Welche Hilfsmittel (Apps, Nikotinpflaster ect.) oder Unterstützungsangebote(Gruppensitzungen, Raucherberatungen) haben Sie bei der Rauchentwöhnung wahrgenommen?
  • Was waren Ihre größten Probleme bei der Rauchentwöhnung?

Vielen Dank das Sie sich für das Interview zeitgenommen haben. Wir werden Ihre Antworten in den kommenden Wochen auswerten und in unser Projekt einbinden. Dürfen wir sie bei weiteren Fragen zu einem zweiten Interview einladen?

Reflexion

Wer hat welchen Beitrag geleistet?

We decided all together on the questions for the interview. Henry created the consent form, Anna answered the starting questions for the blogpost and Alexandra did the research concerning smoking-statistics (in germany, in the EU and worldwide) and wrote the introduction and closing session for the interview as well as the blog post

Was habt ihr gelernt?

We learned how to set up a semi-structured interview and how to formulate the proper questions for it. Furthermore, we learned how to create a consent form for an interview. We also continued to work with the app and became familiar with its functions.

Was lief gut?

The communication in the team worked very well. We were able to distribute the tasks evenly so that everyone had the same amount of work. We were also able to set up questions for an interview using the methods we had learned in the lecture. Furthermore, we were able to successfully create a consent form in which all data protection-related questions are clarified.

Was möchtet ihr verbessern?

We need to improve our time management so that there is enough time to review the answers and correct mistakes.
