Depending on whether data is collected in-person or remotely, there are two methods of [[Primary Data Collection|primary data collection]] - [[Field Surveys|field surveys]] and '''remote surveys'''. Researchers often remote surveys to collect data in areas that are not accessible, or are affected by conflict. In such cases, researchers can still get access to data that can help them solve common development challenges such as lack of access to water, electricity or healthcare.

== Phone Surveys (CATI) ==
A phone survey or a computer-assisted telephone interview (CATI) is one where the enumerator calls the respondent and asks them the questions over telephone. The enumerator enters these responses onto a programmed digital survey, which is then shared electronically with the research team. Phone surveys have 2 major advantages. Firstly, they allow data to be collected remotely, thus saving resources since collecting data through face-to-face interviews can often be expensive. Secondly, they are a great option for collecting data in emergencies or in conflict areas while still retaining the personal touch that researchers prefer.

=== Feasibility ===
== Other Remote Surveys ==
The research team must keep in mind that in a lot of cases, data collection through phone surveys will not be feasible. In that case, they will have to rely on field data collection, or pause data collection in case in-person data collection is not possible. In order to decide whether conducting a phone survey is feasible, ask the following questions:
Besides phone surveys, there are other forms of '''remote data collection''' as well. These include '''web surveys''' and '''recorded surveys'''.
*'''Is it practical to ask these questions over a telephone?'''
=== Web surveys ===
This is an important consideration because in some cases asking questions over the phone can drastically alter the nature of data that is collected, or the manner in which respondents interpret questions in the survey.
In a '''web survey''', the [[Impact Evaluation Team|research team]] directly shares a link to a [[Questionnaire Programming|programmed questionnaire]] with respondents via text or email, without relying on an enumerator. The respondent then answers the questions in the survey by clicking the link to the survey, either on a phone or a laptop. Therefore, in the case of web surveys, it is important for respondents to have access to internet and have the ability to read and understand a written questionnaire.
       
Examples of questions which cannot be asked over the phone are: questions on sensitive topics (such as gender-based violence), and questions with test components (such as a Math test for a school-based survey).
       
* '''How long is the survey?'''
General guidelines and best practices suggest that phone interviews should be short and longer surveys result in lower response rates. If your original questionnaire (for a field survey) took longer than 20 minutes to answer (on average), you might need to reduce the length of your questionnaire or the number of questions when transitioning to a phone survey.
 
However sometimes it is not possible to reduce the duration of the survey without affecting the outcomes of interest. In such cases, you might consider the feasibility of conducting the survey over multiple phone calls.
       
* '''Does a majority of the target population have access to telephones?'''
This is important because if the target population does not have access to telephones , the survey will introduce a [[Selection Bias|selection bias]] into the sample. Further, it will lead to lower response rates and reduce the cost-effectiveness of the survey.
       
* '''Are contact details of the target population easily available?'''
In the case of a '''follow-up survey''' (that is, if a prior round of surveys has already been conducted), it is likely that the research team has already collected contact information about the respondents. But in the case of a '''baseline survey''' (that is, when it is the first round of survey), if the research team does not have access to the contact numbers, they can consider '''random digit sampling (RDS)'''.  This is a method for selecting people for involvement in telephone statistical surveys by generating or selecting telephone numbers at random. However it is only possible when the research team has access to a long list of phone numbers from the population.


If the answers to the above questions are yes, then the research team can move to the next step, that of preparing for remote data collection. In the next section, we discuss the logistics of data collection for a phone survey.
Web-surveys are useful because they reduce survey costs considerably as there are no enumerators involved. They can also be programmed easily using open data kit (ODK)-based tools, without the need for a lot of modification in the drafting process. However, they too suffer from the problem of lower '''response rates''' which arise due to [[Selection Bias|self-selection]].


=== Preparation ===
=== Recorded surveys ===
The steps involved in preparing for phone surveys are different from the steps in [[Preparing for Field Data Collection|preparing for a field survey]]. At each stage of this process, everyone involved in the data collection (government agencies, survey firm, enumerators) must communicate clearly. The research team must carefully work through certain additional steps before conducting a phone survey. These steps deal with the following:
In a '''recorded survey''', the questionnaire is pre-recorded in either written or oral form. Examples of recorded surveys include '''interactive voice response (IVR) surveys''', '''short message service (SMS)''' surveys, and surveys shared via social media and email. These surveys are effective when the surveys are very short (4-5 questions and/or less than 5 minutes on average), have zero or minimal [[SurveyCTO_Programming_Work_Flow#Pseudo Code|skip patterns]], and the questions are very straightforward to understand.  


# '''Timeline for a phone survey.''' <br/> The research team agrees on a comprehensive [[Timeline of Survey Pilot|timeline of a field survey pilot]] at the beginning of the process of preparing a survey. The research team must therefore keep in mind that for a phone survey, each step leading up to, and including, the data collection will take additional time. Therefore it is important to account for this, and allocate a bigger window for each step.
The downside of a recorded survey is that there is a lack of human interaction, and the respondent cannot ask for more clarity on a question. This can lead to lower '''response rates''' compared to phone surveys as well as in-person interviews. They can also result in data that is potentially '''noisy''', that is, the answers either vary a lot or are vague because respondents could not interpret questions accurately.
# '''IRB approvals for a phone survey.'''<br/> Every survey must obtain an [[IRB Approval|IRB approval]]. For a phone survey, the research team must obtain additional approvals for aspects like oral consent, [[Random Audio Audits|audio audits]], and incentives for respondents. (link to Preparing for Remote Data Collection#IRB Approvals)
# '''Procurement-related documents.''' <br/> [[Procuring a Survey Firm|Procuring a survey firm]] involves drafting [[Survey Firm TOR|terms of reference (TOR)]], and preparing a [[Survey Budget|budget]] for each component of the survey process. These procurement-related documents should also reflect the fact that the data collection will be conducted over the phone, and not in-person. The research team must spend time on estimating the costs of procuring adequate equipment, such as setting up a call-center for interviewers.
# '''Questionnaire for a phone survey.'''<br/> The process of [[Questionnaire Design|designing a field survey]] involves various considerations. However, there are additional considerations while designing a phone survey, such as managing the length of the survey, including verbal consent, and including '''audio audits'''.
# '''Remote data collection protocols.'''<br/> Similarly, the protocols for phone surveys are different from [[Survey Protocol|protocols for field surveys]]. Some of these differences are in terms of the team setup, communication protocols and data-quality checks.
# '''Enumerator training.''' <br/>Enumerator training for phone interviews also involves certain additional steps compared to [[Enumerator Training|Enumerator training for in-person interviews]]. This process becomes even more challenging in the case of a work-from-home phone survey, for instance, when a pandemic like COVID-19 prevents the research team from training enumerators in-person. In such cases, the research team must establish certain logistical and content-based changes to the training method. This includes sharing recorded training sessions, preparing '''enumerators''' for follow-up questions from respondents, and discussing steps to keep respondents engaged.
 
'''Note: These steps will be useful in case the the research team has to transition from an in-person survey to a phone survey, for instance, during a pandemic or natural disaster.'''
 
=== Communication during data collection ===
Since there are so many aspects involved in the process of data collection, it is important to make sure that all members of the research team communicate frequently and effectively. Communication becomes even more important when data collection is being carried out remotely. Some guidelines to keep in mind are:
* Set up strong monitoring and communication protocols before starting data collection. Test them during training and the pilot, to identify any gaps that might arise.
* Set up a clear chain of command, and make sure each '''enumerator''' knows who their '''first point of contact (POC)''' is on the research team.
* Schedule regular calls to check-in with each '''enumerator''', and to resolve any concerns they may have.
* Conduct team meetings at least once a week.
* Consider using a team-collaboration and communication tool to maintain a 24X7 channel for communication with supervisors in the survey team. You may add '''enumerators''' too if the survey team is small.
- Monitor data carefully, and on a daily basis. Provide regular feedback to '''enumerators''' on the quality of data being collected.

Depending on whether data is collected in-person or remotely, there are two methods of primary data collection - remote surveys and field surveys. The impact evaluation team (or research team) can conduct remote surveys either to conduct a follow-up survey after an initial round of field survey, or when the study area is not accessible, for instance in the case of a conflict. In such cases, the research team can still get access to data that can help them solve common development challenges such as lack of access to water, electricity or healthcare.

Phone Surveys (CATI)

In phone surveys or computer-assisted telephone interviews (CATI), the enumerator calls the respondent and asks them the questions over telephone. The enumerator enters these responses onto a programmed digital survey, which is then shared electronically with the research team. Phone surveys have 2 major advantages. Firstly, they allow the research team to collect data remotely, which is cost-effective since collecting data through face-to-face interviews can often be expensive. Secondly, they are a great option for collecting data during emergencies or in conflict areas while still retaining the personal touch that researchers prefer.

However, when a research team decides to use a phone survey for collecting data, they must keep in mind concerns about:

Other Remote Surveys

Besides phone surveys, there are other forms of remote data collection as well. These include web surveys and recorded surveys.

Web surveys

In a web survey, the research team directly shares a link to a programmed questionnaire with respondents via text or email, without relying on an enumerator. The respondent then answers the questions in the survey by clicking the link to the survey, either on a phone or a laptop. Therefore, in the case of web surveys, it is important for respondents to have access to internet and have the ability to read and understand a written questionnaire.

Web-surveys are useful because they reduce survey costs considerably as there are no enumerators involved. They can also be programmed easily using open data kit (ODK)-based tools, without the need for a lot of modification in the drafting process. However, they too suffer from the problem of lower response rates which arise due to self-selection.

Recorded surveys

In a recorded survey, the questionnaire is pre-recorded in either written or oral form. Examples of recorded surveys include interactive voice response (IVR) surveys, short message service (SMS) surveys, and surveys shared via social media and email. These surveys are effective when the surveys are very short (4-5 questions and/or less than 5 minutes on average), have zero or minimal skip patterns, and the questions are very straightforward to understand.

The downside of a recorded survey is that there is a lack of human interaction, and the respondent cannot ask for more clarity on a question. This can lead to lower response rates compared to phone surveys as well as in-person interviews. They can also result in data that is potentially noisy, that is, the answers either vary a lot or are vague because respondents could not interpret questions accurately.
