The Quantitative-based study on the integration-related situation, profile and intentions of recognized refugees and beneficiaries of international protection in Greece is a UNHCR-led project assigned to ETH Zurich in scientific cooperation with University College London (UCL). In this context, the Immigration Policy Lab (IPL) at ETH Zurich conducted a study on the integration of refugees and Beneficiaries of Internal Protection (BIP) in Greece. The study aimed at conducting an updated profiling of the population of interest, and exploring the different dimensions of refugees’ integration experience in Greece by subgroup analysis, as well as preparing an action plan for a longitudinal study. This assignment was focused on the implementation of the data collection part of that study via a CATI survey of 3,750 individuals, as well as respondents’ compensation for their participation.

• Recruitment and Training: Recruitment of interviewers fluent in the corresponding language of Greece’s refugee/migrant population considered cultural idiosyncrasies. The questionnaire was translated into all relevant languages, and thorough training was conducted for interviewers and supervisors, including piloting the questionnaire. Survey fieldwork organization, equipment supply, and maintenance were ensured.
  
• Data Collection and Survey Management: Data collection involved contacting 3,750 refugees and BIP in Greece via various methods, including WhatsApp, Viber, or phone calls, with follow-up text messages. Interviews were audio-recorded and files delivered to IPL for analysis. Data cleaning and preparation were carried out, along with managing respondents’ remuneration.
  
• Translations and CATI Script: The questionnaire, translated from English to multiple languages, was incorporated into Survey Solutions CATI and rigorously tested to ensure functionality and proper flow. Timing data for each question and total survey duration were provided to ETH Zurich.
  
• Recruitment & Training of enumerators: Recruitments focused on language skills and availability, with a 3-day training workshop covering questionnaire guidance, CATI form testing, and interviewing vulnerable populations. Interviewers were selected based on language composition matching the sample’s requirements.
  
• Sampling frame: Sampling frames received from ETH Zurich were used for pilot and main data collection phases. Pilot testing was conducted, completing 100 interviews as per language quotas.
  
• Text messaging and respondents’ remuneration management: Messages were sent to inform and thank respondents, and 12€ phone credit compensation was provided within 72 hours of interviews. A dedicated task force was established for efficient compensation management.
  
• Quality control: Audio recordings of two interviews per enumerator were sent for quality analysis during pilot and data collection stages. Additional recordings were provided upon request for ongoing quality assessment.
