Harnessing Technology to Streamline Data Collection

By Guillermo Rojas

The survey process at The DHS Program takes an average of 18-20 months and goes through several steps: survey preparation and questionnaire design, training and fieldwork, data processing, and finally, writing the final report and dissemination. But how do the data get from respondents’ households into the tables you see in the final report?

We employ field interviewers to ask respondents the questions included in the DHS questionnaires – household, woman’s, man’s, and biomarkers. But the way we record their answers changes based on the data collection methodology. At The DHS Program, we employ three types of methodologies to collect data: paper questionnaires, Computer Assisted Field Editing (CAFE), and Computer Assisted Personal Interviews (CAPI).

DHS Model Household Questionnaire, Page 1

DHS Model Household Questionnaire, Page 1

The vast majority of DHS surveys in the past 30 years have used paper questionnaires to collect data. With physical paper questionnaires in hand, field interviewers go from house to house, ask the questions of the respondents, and manually fill out the questionnaires. After interviewers visit all households within a cluster, supervisors ship the questionnaires to the survey central office. Upon arrival, the data processing begins for that particular cluster.

The Computer Assisted Field Editing (CAFE) system allows for editing to happen as interviews are taking place. With CAFE, interviewers still use paper questionnaires, but Field Editors enter the questionnaires into computers while the team is still in the cluster. Essentially, questionnaires are fully field edited by an intelligent data entry program. With this type of data collection approach, Field Editors provide feedback to interviewers on any anomaly identified by the program such as interviewers missing full sections of the questionnaire or wrongly executing critical skip patterns. At this point in the survey process, it is relatively easy to send the interviewer back to the household to resolve any problems. With this approach, there is no need for main data entry as the data entered in the field is sent via the internet to the central office. Therefore, CAFE speeds up the survey process as cluster data files are available as soon as the data arrive to the central office for further processing.

The 2005 Colombia DHS was the first DHS survey to utilize the Computer Assisted Personal Interview (CAPI) methodology. CAPI does not involve any type of paper questionnaire—it is entirely digital. Back in 2005, field interviewers used bulky laptops, though nowadays we use lighter tablets and notebook computers.

The DHS CAPI data collection system consists of three comprehensive subsystems:

1. A system for interviewers to facilitate the interview process

2. A system for supervisors to centralize the data collected by interviewers

3. A system for the central office to monitor the fieldwork operation and to further process the data

The DHS CAPI system uses Bluetooth technology to transfer and share data among members of the same fieldwork team. Supervisors then send data to the central office headquarters using the Internet File Streaming System (IFSS), a cloud-based electronic file delivery system developed by The DHS Program. The primary objective of the service is to deliver files from one user to another in an exceptionally fast and secure way.

In the past 30 years, we’ve witnessed an incredible change in technology, especially with both hardware and software. When I first started at The DHS Program, running the program to impute the woman’s events dates could easily take more than six hours for a survey with a sample size of 2,000 to 3,000 households! Nowadays, with sample sizes of 20,000 to 30,000, this program takes just one to two minutes to run. CAFE and CAPI allow us to use the power of these newer innovations in technology to make sure that we carry out DHS surveys as efficiently and accurately as possible.

The Nutrition Landscape in India

This post is part of a series commemorating 30 years of The DHS Program.

By Fred Arnold

Historically, India has suffered through devastating periods of famine, but due to the Green Revolution, improved food storage and distribution, and other factors, famine has been all but eradicated in the country. However, malnutrition continues to threaten the health of India’s population.

NFHS-3

NFHS-3

The National Family Health Surveys (as DHS surveys are known in India) have been documenting the nutrition situation in India since 1992 (by measuring the height, weight, and anemia status of children and adults, and by assessing infant and young child feeding practices). These surveys have brought to the nation’s consciousness the excessively high levels of stunting, wasting, underweight, and anemia that young children in India continue to suffer from. The most recent NFHS survey (NFHS-3) found that nearly half of children under five are stunted, 43% are underweight, 20% are wasted, and 7 out of every 10 children are anemic. Stunting among children was as high as 60% in the lowest wealth quintile, but was still considerable (25%) even in the highest wealth quintile. These findings were widely reported in the media, were agonized over by international organizations and NGOs, and were prominently discussed at the highest levels of government. In two national addresses, Prime Minister Manmohan Singh revealed that he had seen the results of the National Family Health Survey, and he declared the poor nutrition of India’s children to be “a national shame.” He immediately responded by writing a letter to the Chief Ministers of every state in the country, ordering them to take up the fight against malnutrition “on a war footing” and to report back to him every quarter on the progress that had been made.

Based on the NFHS-3 findings, that same year I wrote a paper on the nutrition landscape in India, which was published in Demography India and presented as the keynote speech at the Annual Meeting of the Indian Association for the Study of Population. That reached yet another important constituency that joined the national dialogue on nutrition.

Another aspect of nutrition that was documented in that paper was the emerging dual burden of simultaneous undernutrition and overnutrition among Indian adults. About one-third of women and men were abnormally thin and about 1 in 8 were overweight or obese, meaning that only about half of adults had a normal nutritional status. The figures are even more alarming in certain segments of the population. Thirty to forty percent of women were overweight or obese in some of India’s largest cities, and even in urban slums, 20-30% of women fell in that category.

Since NFHS-3, there have been encouraging signs of improvements in nutrition in some places, but discouraging signs of stagnation or deterioration in others. The results of the NFHS-4 survey, which is just about to go into the field, are eagerly awaited to provide more definitive information on the current nutrition situation. And when the next chapter in India’s nutrition history is written, NFHS will be there to monitor trends and provide vital information to guide informed policymaking and program planning.

Gender in the Demographic & Health Surveys: Past, Present, & Future

This post is part of a series commemorating 30 years of The DHS Program.

When I first started at The DHS Program in late 1993 as a Women-in-Development Specialist, the survey questionnaires contained few questions that could shed light on the impact of gender on demographic behavior and health. While the questionnaires were designed to collect all kinds of information on women’s and children’s health, women’s use of contraception, fertility, mortality and nutrition, there was virtually no information on the status of the women themselves other than information on their education and employment. In other words, there was little information that provided insights into the gendered context within which the health and demographic behavior of women and households was being determined.

1995 Egypt DHS

1995 Egypt DHS

So I had a lot of work to do. My challenge was to develop a parsimonious module of questions that in the future could potentially be used by DHS surveys across the world to better understand the role that gender plays in demographic and health outcomes. To this end I put together a set of questions on women’s status based on a thorough literature review and an examination of several studies that used questionnaires to measure women’s status and gender relations in the household. Once ready we managed to include this module of questions in the 1995 Egypt DHS. Preparing the module was challenging since the literature provided mostly proxy indicators of women’s status at the household level, but few that could directly measure empowerment. Additionally, since one of the key features of The DHS Program is that it provides comparable data across countries, I needed questions that had similar meaning across cultures with widely varying perceptions of women’s roles. The pilot of the Women’s Status Module in the Egypt DHS yielded a lot of useful information and helped determine the key indicators that would be useful to have for most countries such as the questions on women’s role in household decision making, their attitudes towards spousal violence, and barriers to accessing health care for themselves.

1998 Nicaragua DHS

Another gender-related topic that really increased in importance during my tenure as the Senior Gender Advisor to The DHS Program is domestic violence. The women’s status module implemented in Egypt contained only a couple of questions on women’s experience of domestic violence and the 1990 and the 1995 Colombia DHS surveys included country-specific questions on domestic violence. Then in 1998, a module of questions that utilized a modified conflict tactics scale approach (Strauss 1990) to the measurement of violence was implemented in the Nicaragua DHS. It was this module that became the foundation for the core DHS Domestic Violence Module which was finalized and piloted around 2000. Overtime we also developed a protocol for the ethical collection of data on violence, particularly for the protection of female respondents and field interviewers. However, having a standardized module and protocols for its implementation, did not mean that countries were immediately interested in collecting information on domestic violence. There was first a need to try and overcome commonly held beliefs that domestic violence was not a State concern and had no place in a demographic and health survey. Additionally few believed that women would be willing to talk about their experiences of violence.

The 1995 Egypt DHS marked a new chapter in the life of The DHS Program. Questions on women’s empowerment are now part of the core questionnaire and asked in most countries. The Domestic Violence Module has been included in more than 95 surveys in over 50 countries. Survey data have been used for major legislation, advocacy efforts, and national programs to protect women in their own homes in countries as diverse as Moldova, Uganda, Timor Leste, and Zimbabwe. Analysis of DHS data has convincingly linked violence with negative reproductive health outcomes and HIV, showing that violence is an important public health issue as well as a violation of individual rights.

In the coming years, The DHS Program will continue to collect more information on women’s empowerment. The 2014 revised survey instruments now include questions on women’s ownership of mobile phones, personal bank accounts, and ownership and co-ownership of property. We have come a long way since the first pilot module on women’s status, and we will continue to be on the forefront of research into women’s lives.

A look back at the 1986 Liberia DHS

2013 Liberia DHS

2013 Liberia DHS

The fact that Liberia is currently battling the Ebola crisis makes it harder to appreciate the fact that the recently released report on the 2013 Liberia Demographic and Health Survey (LDHS) showed improvement in most of the health-related indicators since the 2007 LDHS was carried out. I prefer to remember Liberia the way it was during the first DHS, before Ebola and before the civil war.

The 1986 LDHS was the first DHS in Africa and only the second worldwide. I was the country manager assigned to cover the survey. However, because we recruited interviewers from the local areas in which they would work and it was deemed too expensive to bring them all to one central place, we decided to hold two simultaneous training courses. I travelled the 6 hours to the town of Zwedru, while my boss (then Regional Coordinator, later DHS Director) Ann Way, was in charge of the training in Monrovia. Zwedru was a small quiet city and I was lucky to be able to stay in a USAID guest house for the month-long training. We also had a pleasant, airy new building for the training. Ann, however, was training in an old school with broken windows in Monrovia.

Although we had conducted a pretest several months before, this was the first DHS main interviewer training for both of us. Consequently, we had a number of questions that came up. How do you estimate a person’s age when they don’t have any documents and can’t remember who was president when they were born? Do you list someone in the household schedule who works away from home but comes home every weekend? Although we had a detailed interviewers’ manual, some of these questions had not been fleshed out. And of course, there were a slew of administrative issues too, like locating enough vehicles, getting payments wired from the U.S., etc.

Ann and I set up a plan to call each other every few days. Since this was before cell phones and even land lines were pretty scarce in Liberia, I would walk to a pay phone in Zwedru, put in several of the heavy Liberian coins (nicknamed “Doe Dollars” after the Liberian President) and call her in Monrovia. We would review various issues and catch up on news. It sounds so quaint now, but it was like a lifeline for me and I remember saving up the coins so that when the phone indicated the time was running out, I could drop another dollar in and talk a bit longer. We always had to remember to set up the time for the next call so that we would be sure to be at our respective phones. We don’t realize how much cell phones have changed the survey landscape.

Celebrating 30 years of DHS

2014 marks the 30th anniversary for the USAID-funded Demographic and Health Surveys Program and my eleventh anniversary as Senior Advisor for Communication with the project.  Much has changed over the past three decades: we’ve done many more surveys and much more complex surveys, added biomarkers, conducted more formal capacity building, and varied the kind of dissemination products and activities.  What hasn’t changed is how much people all over the world value the DHS.

When I joined The DHS Program—then MEASURE DHS—in 2003, I was a devoted DHS user, relying on surveys for background information to inform behavior change communication programs.  But I knew very little about how national governments and development partners used the surveys. It was my first trip for the project that gave me a whole new perspective on the impact of DHS findings.

2003 Nigeria DHS

2003 Nigeria DHS

I went to Abuja, Nigeria for the launch of the 2003 Nigeria DHS Final Report. More than 500 people crammed into the Sheraton Hotel Conference Centre designed to hold only about 350.  The morning session included opening prayers, introductory speeches by four government ministers, the USAID Mission Director, the head of the National Population Commission, the Chief Economic Advisor to the President, and more.  Finally, we got to the data—a short key findings presentation of the survey results highlighting childhood vaccination rates from Nigeria and from DHS surveys in other African countries (see chart below).

Percentage of children who received all basic vaccinations in select African countries from the 2003 Nigeria DHS Key Findings

At the time, only 13% of Nigerian children had been fully vaccinated, putting Nigeria dead last in Africa.   When this statistic was presented, all 500 participants in the audience sat in shocked silence. The data told the story, and the Nigerians were not happy to be so far behind their smaller and much poorer neighbors. The DHS results were a critical factor prompting Nigerian leaders to focus on improving national immunization programs. While still not impressive, vaccination coverage for Nigerian children has doubled since 2003, reaching 25% in the 2013 DHS.

I heard another example of the impact of the 2003 Nigeria DHS during my trip.  The survey found that only 12% of households owned mosquito nets. As a result, a DFID-funded Society of Family Health project decided to increase malaria prevention activities and add insecticide treated nets to its roster of social marketing products.  For both the national government, private sector, and development partners, the DHS made the difference.

I’m immensely proud to introduce this blog series, which will highlight many different stories of DHS over the years. In the coming weeks, you will hear from DHS leaders over the years, including Sunita Kishor, Martin Vaessen, Trevor Croft, Guillermo Rojas, Fred Arnold, and Annie Cross, on topics ranging from gender & women’s issues in the DHS to nutrition in India, Data Processing and collection methods to experiences from the first DHS in Liberia. I hope this series unlocks some of DHS history for you, our users. Here’s to 30 years of DHS!

DHS Curriculum Training in Kenya

Participants in the DHS Curriculum Training in Mombasa, Kenya

Participants in the DHS Curriculum Training in Mombasa, Kenya

By Peninah K. Masibo

The Demographic and Health Survey (DHS) curriculum is a course that builds the capacity of faculty and students in African universities to understand and use DHS surveys. The course covers a general introduction to the DHS, basic statistics and demographic health terms, indicators in the DHS, conducting a DHS, collecting data on HIV/AIDS and malaria as well as dissemination and use of DHS data.

In May 2014, 40 participants from the Technical University of Mombasa and Pwani University went through a five day training on the DHS curriculum course. Participants were an interesting mix of senior university professors, deans of schools, heads of academic departments, members of various faculties, and graduate students. The participants came from various fields of specialization including medical sociology, public health, environmental science, laboratory management, entomology, epidemiology, and medicine.This range of scholars made it so much fun and generated very hearty debates regarding the DHS curriculum and the applicability of the materials in university teaching, learning, and research.

The DHS curriculum training spurred participants into finding ways of integrating DHS into their university teaching. Applicable fields include statistics, epidemiology, research methods, vector control, parasitology, human nutrition, medical laboratory, HIV/AIDS, research methods, and medical sociology. The graduate students from the Master of Public Health (MPH) programs at both universities found the training very applicable to their course and field work activities.

2008-09 Kenya DHS

One of the prominent areas of discussion was the new malaria module. The Kenyan coastal region is a malaria endemic zone, and the module is very relevant for research and academic teaching in the institutions of higher learning. The malaria trivia game made it a very memorable learning experience. Other interesting discussions centered on emerging health issues such as cervical cancer. Participants were thrilled to learn of the inclusion of cervical cancer knowledge questions in some DHS countries.

The training created a lot of interest in learning how to use DHS data for individual and group research activities. Working in small groups made the training very exciting allowing the graduate students to lead discussions along with senior faculty.

The training was well organized with full participation from the two public universities. The Deputy Vice Chancellor (DVC) of Academics, Research, and Extension at Technical University of Mombasa made the official opening speech. She highlighted the importance of DHS in informing health and development policy in Kenya and globally. The closing ceremony and the certificate award were conducted by the DVC of Academics and Student Affairs at Pwani University. He observed the need for participants to apply the newly acquired knowledge and skills from the training to enhance the universities’ training activities.
