Designing Effective Mobile Phone Surveys: Insights from Mozambique on Optimizing Call Attempts and Evaluating Response, Refusal, and Contact Rates among Refugees and Asylum Seekers

Résumé

This study aims to provide a detailed analysis of the call attempts and sample design phase in Computer Assisted Telephone Interviewing (CATI) when applied to forcibly displaced populations. The sampling frame consisted of 680 individuals from initial batch and 1400 individuals from the latter which was currently updated, all refugees and asylum seekers. Data was collected from 400 individuals using the UNHCR registration database, ProGres.The initial focus was on assessing response, refusal, contact, and cooperation rates. Additionally, the study examined the impact of survey length on refusal rates. This analysis was followed by a comparison of respondent profiles with the sampling frame to estimate representativity of the final sample. To optimize the ideal number of calls, the study assessed call attempts, particularly emphasizing differences in reasons for non-responses specific to forcibly displaced populations. Only 30 percent of call attempts resulted in phone contact, and among those, only 18 percent successfully completed the surveys. Kaplan Meier survival estimations were employed to illustrate the likelihood of reaching respondents based on the number of attempts. The findings underscore the importance of a meticulous sampling design to ensure data quality and minimize bias when employing CATI for forcibly displaced populations.
