1. BASIC INFORMATION
1.1 LOCATION
The Asian Barometer 2014 Survey covered the entire Philippines, and had four major
study areas: National Capital Region (NCR), Balance Luzon (outside NCR), Visayas and
Mindanao.
1.2 POPULATION
The population of the Philippines in 2010 was 92,097,000, with estimation at
100,096,496 as of July 1, 2014. Fifty percent of the population is urban, with the median
age as 23.2 years.1
1.3 GOVERNMENT2
The Philippines is a democratic republic with the president as the head of the state and the
government. It is a unitary state with the exception of the Autonomous Region in Muslim
Mindanao, which is largely free from the national government.
The president is elected by popular vote for a single six-year term through the
first-past-the-post rule. The bicameral Congress consists of the Senate and the House of
Representatives. Members of the Senate are elected to a six-year term (limited to 2
consecutive terms). The Senate is composed of 24 senators who are elected at-large by
the electorate. The members of the House of Representatives are elected to a three-year
term (limited to 3 consecutive terms). In 2013, representatives were elected from 234
legislative districts (single-member district), and no more than 20% of the total number of
representatives are elected through the party-list. Currently, there are 58 representatives
elected through the party-list, which make the total number of the representatives to be
292. Voters vote for a single party-list organization and organizations that garner at least
2% of the total number of votes win one seat for every 2% up to a maximum of three
representatives. Major parties are not allowed to participate in the party-list election.
The current president is Benigno S. Aquino III, who was elected in June 2010. The latest
legislative election was held in 2013, with the president’s party—the Liberal
Party—controls 39% of the seats.

1.4 ECONOMIC PERFORMANCE3
The GDP per capital is USD 7,412 for the 2015 estimate. The annual economic growth is
forecast to be 5.0% in 2015. The Philippines has high unequal income distribution, with
the Gini coefficient as 43.0.
1.5 IMPORTANT POLITICAL AND SOCIAL EVENTS4
The Philippines has territorial disputes with China and Taiwan in the South China Sea. In
May 2013, major diplomatic row erupts between Taiwan and the Philippines after
Filipino coastguards killed a Taiwanese fisherman in disputed waters.
In November 2013 Typhoon Haiyan swept across central areas of the country, leaving
devastating and thousands of dead in its wake. A major international aid efforts was
organized to help more than four million people affected.
In March 2014, MILF rebel group signed a peace deal with the government that brought
an end to one of Asia’s longest and deadliest conflicts.

3. RESPONDENTS 3.1 CRITERIA OF SELECTING RESPONDENTS
Data was gathered through face-to-face interviews of voting-age Filipino adults aged 18
years old and above. The survey asked a host of questions about political, social and
economic issues, some undertaken as regular indicators monitored over time and others
reflective of current concerns. It also obtained information and background characteristics
about the household and family members. The questionnaire was administered thru paper
and pencil interviews (PAPI).
3.2 RESEARCH ETHNICAL REVIEW
In the Philippines there is no need to obtain any permission for any research type. For
the ABS IV we did not need to go through the review process in the Philippines.
However, before the beginning of interview process, the interviewers informed all
interviewees that ‘we will not record your name or identifying information about you
on the questionnaire. So no one will know who gave which answers to our questions.
There is no risk to you in participating in the survey. There is also no benefit to you in
participating in the survey. But if you answer our questions, you will help us
understand how the public feels about issues facing the country today. Your
participation in the survey is voluntary. If there are any questions you don't want to
answer you don't have to answer them. And you can stop participating in the survey at
any time. ..’
4. SAMPLING PROCESS AND METHODOLOGY 4.1 SAMPLING SIZES AND ERROR MARGINS
An indicator of data quality is the standard error of the estimate, on which the margin for
sampling error is based. As survey statistics are mostly proportions, the key measure of
data precision is the standard error of a proportion taken from a sample. It is computed as
follows:
Where Z, at 95% confidence level is 1.96; p is the sample proportion estimate and n is the
+ _ Z * p(1-p) n
sample size. The overall sample size of 1,200 voting-age adults gives a maximum error
margin of ± 2.83% at the 95% confidence level, assuming a simple random sampling
design. The sampling error is at its highest when the true proportion being estimated is
close to 50%.
The following approximate 95%-confidence margins for sampling error should be made
when aggregating data at various levels:
Region Sample Size Error margin
Philippines 1,200 ±3%
National Capital Region 300 ±6%
Balance Luzon 300 ±6%
Visayas 300 ±6%
Mindanao 300 ±6%
However, somewhat higher error margins should be expected since multi-stage cluster
sampling was used; this design-effect is not readily measurable through established
statistical software.
4.2 SAMPLING SCHEME
The Philippines was divided into four study areas: National Capital Region (NCR),
Balance Luzon, Visayas, and Mindanao (See Figure 1. Map of the Philippines).
Multi-stage probability sampling was used in the selection of sample spots. The allocation
of sample units in each stage was as follows:
Region Sample
Province
Sample
MunicipalitySpots Respondents
National Capital
Region -- 17 60 300
Balance Luzon 10 15 60 300
Visayas 5 15 60 300
Mindanao 6 15 60 300
Total 21 62 240 1200
4.2.1 FIRST STAGE-SELECTION OF PSU
4.2.1.1 NATIONAL CAPITAL REGION (NRC)
For NCR’s first stage, 60 barangays were distributed among the 17 NCR cities and
municipalities in such a way that each city/municipality was assigned a number of
barangays that was roughly proportional to its population size. An additional provision
was that each municipality must receive at least one barangay. Barangays were then
selected from within each municipality with probability proportional to size (PPS). See
Figure 2 for an illustration of the sampling scheme for NCR.
4.2.1.2 OUTSIDE OF THE NATIONAL CAPITAL REGION: BALANCE
LUZON, VISAYAS, MINDANAO
Balance Luzon was divided into 6 regions: Region I, CAR+Region II, Region III, Region
IV-A, Region IV-B and Region V; Visayas into 3 regions: Region VI, Region VII and
Region VIII; and Mindanao into 6 regions; Region IX, Region X, Caraga, Region XI,
Region XII and ARMM. See Figure 3 for an illustrative example of the sampling scheme
for Balance Luzon. Using probability proportional to population size (PPS) of the region,
the allocation of 10 provinces in Luzon, 5 in Visayas and 6 in Mindanao were as follows:
Luzon Visayas Mindanao
Region I 1 Region VI 2 Region IX 1
CAR+Region
II 1 Region VIII 2
Region X 1
Region III 3 Region VIII 1 Caraga 1
Region IV-A 3 Region XI 1
Region IV-B 1 Region XII 1
Region V 1 ARMM 1
Total 10 5 6
The non-quota provinces were selected without replacement using probability
proportional to their remainders. The remainders are fractions derived when the
proportion of the regions (based on their respective study area) are multiplied by 10 for
Luzon, and 5 for Visayas and 6 for Mindanao. For instance, if 1.28 is obtained for Region
I, then 1 province is assigned to this region and remaining fraction of 0.28 is included for
the allocation of the non-quota province.
Given the target number of provinces for each region, sample provinces were then
selected by PPS, without replacement. An additional provision is that each region must
receive at least one province.

4.2.2 SECOND STAGE-SELECTION OF SSU
4.2.2.1 NATIONAL CAPITAL REGION (NRC)
National Capital Region does not have SSU. It goes straightly to the household selection.
4.2.2.2 OUTSIDE OF THE NATIONAL CAPITAL REGION: BALANCE
LUZON, VISAYAS, MINDANAO
Within the study areas of Luzon, Visayas and Mindanao, 15 municipalities were allocated
among the sample provinces. The number of municipalities for each study area was
multiplied by the proportion of the provinces. The resulting integers became the number
of municipalities in that province. If there were remaining municipalities to be allocated,
they were distributed using probability proportional to the remainders. Sample
municipalities were then selected from within each sample province with probability
proportional to population size, without replacement. An additional provision was that
each province must receive at least one municipality.
4.2.4 THIRD STAGE-SELECTION OF SPOTS
4.2.4.1 NATIONAL CAPITAL REGION (NRC)
National Capital Region does not have the third stage. It goes straightly to the household
selection.
4.2.4.2 OUTSIDE OF THE NATIONAL CAPITAL REGION: BALANCE
LUZON, VISAYAS, MINDANAO
Once the sample provinces have been selected, 60 spots for each of the major areas were
allocated among the sample provinces. Using the target number set for each spot in each
region, the spots were distributed in such a way that each province was assigned a number
of spots roughly proportional to its population size.
Luzon Visayas Mindanao

Region X 12
Region III 15 Region VIII 14 Caraga 6
Region IV-A 16 Region XI 12
Region IV-B 5 Region XII 11
Region V 9 ARMM 9
Total 60 60 60
Sample barangays within each sample municipality were selected with probability
proportional to size. Sample barangays were then classified as urban or rural based on the
latest National Statistics Office classification (2000).
4.2.4 FOUTH STAGE-SELECTION OF HOUSEHOLDS
4.2.4.1 NATIONAL CAPITAL REGION (NRC)
In each sample barangay, five (5) households were established by systematic sampling.
Designated starting points were randomly assigned - it was either: 1) a
municipal/barangay hall, 2) a school, 3) the barangay captain's house, 4) a
church/chapel/mosque, 5) a health facility, or 6) a basketball court. A random start from
1-6 was also randomly generated for each spot. Thus, if a particular spot has a random
start of 4, the first sample household should be the 4th household from the designated
starting point. Subsequent sample households were chosen using a fixed interval of 5
households in between the sampled ones; i.e. every 6th household was sampled.
4.2.4.2 OUTSIDE OF THE NATIONAL CAPITAL REGION: BALANCE
LUZON, VISAYAS, MINDANAO
For the fourth stage, within each sample spot, five (5) households were established by
systematic sampling. In urban barangays as well as in rural barangays, designated starting
points were randomly assigned - it was either: 1) a municipal/barangay hall, 2) a school, 3)
the barangay captain's house, 4) a church/chapel/mosque, 5) a health facility, or 6) a
basketball court. A random start from 1-6 was also randomly generated for each spot.
Thus, if a particular spot has a random start of 4, the first sample household should be the
4th household from the designated starting point. The sampling interval for urban
barangays was six, while for rural barangays, it was two.
4.2.5 FIFTH STAGE-SELECTION OF RESPONDENT
4.2.5.1 NATIONAL CAPITAL REGION (NRC)
For the last stage, in each selected household, a respondent was randomly chosen
among the household members who were 18 years of age and older, using a
probability selection table. In selecting the probability respondent of a household,
only male family members were pre-listed in the probability selection table of
odd-numbered questionnaires; only female family members were pre-listed for
even-numbered questionnaires.
4.2.5.2 OUTSIDE OF THE NATIONAL CAPITAL REGION: BALANCE
LUZON, VISAYAS, MINDANAO
For the fifth and final stage, as discussed earlier, a respondent was randomly chosen from
among the voting-age adults in each selected household using a probability respondent
selection table. A respondent not contacted during the first attempt was visited for a
second time. If the respondent remained unavailable, or in cases where there was no
qualified probability respondent of a given gender, the interval sampling of households
would continue until five sample respondents were identified.
4.3 NUMBER OF CALLS AND SUBSTITUTION/ALTERNATE SAMPLES
A respondent not contacted during the first attempt was visited for a second time. If
the respondent remained unavailable, or in cases where there was no qualified
probability respondent of a given gender, the interval sampling of households would
continue until five sample respondents were identified.
Only three barangays out of the 240 barangays were substituted. Two barangays were
substituted for security reasons and one because it is in a remote/far-flung area. They
are:
1. Brgy. Datu Esmael (Bago-a-ingud), Dasmarinas, Cavite (Balance Luzon): The
barangay captain did not allow the interviewers to conduct the interviews because of
his concern for their security, particularly due to the prevalence of drug addicts in
some parts of the barangay;
2. Brgy. Lanao Dakula, Parang, Sulu (Mindanao): This barangay was replaced
because of ongoing security operations in that area at the time of the interviews; and,
3. Brgy. Panampalay, Pres Manuel A. Roxas, Zamboanga Del Norte (Mindanao):
This barangay was replaced because of its remote/far-flung location, and there were
no public vehicles going to this barangay at the time of the interview because of the
heavy rains.
4.4 SURVEY STATISTICS
Shown in the table below are the final dispositions of case codes. These were slightly
modified for area-based in-person household surveys, based on the American Association
for Public Opinion Research (AAPOR) Standard Definitions on Final Dispositions of
Case Codes and Outcome Rates for Surveys.
A total of 3,345 households were contacted for the survey, of which 1,200 were
completed interviews. There were 1,317 eligible cases for which no interview is
obtained: 992 were cases of the respondent away/not available and 290 cases of known
respondent refusal.
There were 650 cases of unknown eligibility and no interview: 478 were cases of nobody
home, and 113 cases of unknown if household has an eligible respondent. There were 178
cases of households with no eligible respondents.
Category Frequency Percent

HH-level language problem 2 0.1
Not Eligible 178 5.3
No eligible respondent 178 5.3
Total 3,345 100
The refusal rate for this survey is 52.3%. SWS computed the refusal rate (RR) following
the definition that refusal rate is one minus the number of complete interviews (I) with
reporting cases divided by the number of eligible cases in the sample:
1I
I P R NC O
Where
I = Complete interview
P = Partial interview
R = Refusal and break-off
NC = Non-contact
O= Physically or Mentally unable/incompetent
Shown in the table below are the response rates disaggregated by area, locale, class, sex,
age and educational attainment of the respondents. The refusal rates are lower in Visayas
(41%) and Mindanao (37%), in rural areas (40%), among females, among older adults
aged 25 and above and among those with elementary education or less.

5. RESEARCH METHODOLOGY 5.1 PREPARATION
5.1.1 QUESTIONNAIRE
The final questionnaire is composed of two modules: the Main Questionnaire and the
Socio-Demographic (SDC) Questionnaire. The Main Questionnaire has 172 questions,
while the SDC Questionnaire has 15 questions, for a total of 187 question items.
The definitive language version of the core questionnaire, English, was translated into
Filipino. The Filipino version of the questionnaire became the basis of the other language
versions translated by the pool of SWS language translators: Bicolano, Cebuano,
Hiligaynon, Iluku, Tausug, and Waray.
5.1.2 PRE-TESTING AND FINALIZING QUESTIONNAIRE
The Filipino version underwent cognitive pretests to make sure that the messages were
conveyed accurately. In addition, cognitive pre-testing enabled SWS to:
- Determine the time length of the interview;
- Improve the wording of the questions, if necessary;
- Eliminate unnecessary questions or add new items, as the case may be;
- Test question sequence and identify bases;
- Correct and improve translation;
- Change open-ended questions into multiple-choice questions;
- Find out which items are conceptually vague;
- Check accuracy and adequacy of the questionnaire instructions;
- Determine whether the focus of the question is clear; and,
- Identify interviewer's recording difficulties
5.1.3 TRAINING
Two sets of training were conducted prior to the fieldwork implementation – one for the
Supervising Anchors (SAs) and assistant Supervising Anchors (ASAs), and one for the
field interviewers on-site.
5.1.3.1 SUPERVISOR
A general training for the five (5) SAs and seven (7) ASAs was conducted at the SWS
office in Quezon City. The Supervising Anchors (SAs) are regular SWS staff who
directly report to the Project Director (Ms. Linda Guerrero), the Field Manager (Ms.
Germelita Caron), and, Project Manager (Ms. Iremae Labucay). The ASAs are regular
project-based assistants. They are in-charge of the overall day-to-day monitoring of the
conduct of the survey implementation as well as the administration of fieldwork logistics.
The general training was conducted by the Project Manager. The SAs/ASa, in turn,
conducted the training of field interviewers.
5.1.3.2 INTERVIEWER
The field interviewers’ trainings were conducted on-site, or in strategic, central locations
where the interviews were to be conducted.
Training Time. The minimum training time for interviewers was 2 days prior to field
implementation. The third day was the start-off, where the SAs/ASAs observed the field
interviewers on their first interviews.
Training Activities. These mainly consisted of:
One or two days office training to learn the basics of the project; and, Mock interviews
among participants, i.e. field interviewers interviewing supervising anchors as
respondents are done to get accustomed to the flow of interviewing and questionnaire
format. Interviews were practiced with a supervisor around until the interviewer could be
left on her own.
5.2 FIELDWORK
5.2.1 WORKERS ON HAND
For this project, a total of 53 field interviewers and seven project assistants were deployed.
The field interviewers and project assistants were from the pool of SWS interviewers.
Thirty encoders were hired for data processing.
5.2.2 SUPERVISION
5.2.2.1 EVALUATION OF INTERVIEWER'S WORK
All first interviews of each field interviewer were observed by her field supervisor, and
then evaluated. Only after meeting a certain evaluation criteria was an interviewer left to
interview on her own, although her field supervisor always stayed within the vicinity of
the sample spot to conduct checks.
Supervisors reporting to the field manager monitored the study full-time. They observed
interviewers (at least 10% of total interviewers were observed by supervisors),
followed-up and did surprise checks on the field interviewers. They also ensured that field
logistics were received promptly and administered properly.
5.2.2.2 SPOT-CHEKING
Part of quality control was to make sure at least 30% of each interviewer’s output was
spot-checked and back-checked. Once an incomplete or inconsistent answer was spotted
in the questionnaire, the field interviewer went back to the respondent’s house to re-ask
the question for verification.
5.2.2.3 RE-TESTING
There is no re-testing but after each interview, the interviewer was asked to go over her
own work and check for consistency. All accomplished interview schedules were
submitted to the assigned group supervisor who, in turn, edited every interview.
5.3 FIELD EDITING
5.3.1 DATA PROCESSING
All the completed questionnaires were returned to the SWS office for data processing.
A CSPro-based program was used for data entry, and SPSS for the generation of data
tables.
5.3.2 DATA ENTERING AND CLEANING
Office editors conducted final consistency checks on all interviews prior to coding.
Encoded data were validated (100%) by a group separate from the encoders.
All data tables generated were checked.
5.4 ISSUES IN THE IMPLEMENTATION OF THE QUESTIONNAIRE
Overall, the interviewers assessed that the questionnaire was relatively easy to implement
compared with other SWS questionnaires that they have recently implemented. In
particular, they cite that because there were only a few items with skipping instructions,
the flow of the interview was facilitated. There were also a few questions that needed to
be cross-checked for consistency.
They observed that the questions were of interest particularly to the younger, more
educated respondents from urban areas.
The problems encountered in the implementation of the questionnaire were primarily
related to the length of the questionnaire. Some of the questions were also too wordy or
verbose, which contributed to the questionnaire being lengthy. The use of show cards
with the answer categories of the questions could have reduced the overall length of the
interview.
The questionnaire, with 187 question items, took an average 62 minutes to be completed,
or three (3) questions per minute. Several respondents, in fact, complained to the
interviewers that the questionnaire was too lengthy. There were a few cases of the
interviews terminated because of the lengthy interviews. One interviewer noted a case of
an elderly respondent who fell asleep while being interviewed. In some cases, the
respondents asked the interviewers to repeat reading to them the answer categories. The
interviewers also noted that some of the respondents seemed bored in the middle of the
interviews.
The interviewers themselves found the questionnaire too lengthy to implement, to the
extent that some of them suffered sore throat following the interviews. One interviewer
shared that a respondent had offered her a glass of water to drink when she had difficulty
enunciating the questions near the end of the interview.
Aside from the issue of the questionnaire being too lengthy when implemented, the
interviewers had little difficulty with the implementation. On the questions related to
participation in elections, the interviewers reported that several respondents seemed
hesitant to answer, but eventually gave their responses without prompting or probing
from the interviewer.
Just before the fieldwork started, a security alert was raised for Southern Mindanao due to
intelligence reports of possible terror threat in key cities in the region, particularly in
Davao City, Cagayan de Oro City, Koronadal City, and Kidapawan City. This heightened
security situation, however, it did not affect the survey implementation, that is, it did not
cause any delay in the fieldwork.
5.5 RECOMMENDATIONS FOR FURTURE IMPLEMENTATION
To address the issue of the interview being lengthy, SWS strongly suggests expanding
the use of show cards with the answer categories of the questions, from which the
respondents will choose their response to the survey question. The use of show cards with
answer categories would facilitate the survey administration in several ways.
For one, it could eliminate the need for the interviewer to repeat reading the answer
categories upon the request of the respondent. Show cards with answer categories would
also minimize the recency effect, or the tendency of respondents to choose the answer
category that they would hear last. In addition, using show cards in repetitive questions,
such as putting the agree-disagree battery statements in show cards, would minimize the
probability of the respondents giving mechanical answers as it would give the
respondents sufficient time to think carefully before they give their responses. It would
also address the issue of the respondents getting bored or sleepy in the middle of the
interviews, as they would feel that they are active participants to the interview process.
The expected primacy effect of show cards with answer categories, or the tendency of
respondents to choose the answer category that they would see first in the list, could be
mitigated by using a rating board-ring card with answer categories. Ring cards are
show cards that are bound by together usually ring bound, hence the name “ring card”.
The rating boards are where the answer categories are written. Ring cards assure that the
statements are shown to the respondents sequentially. (See Figures 4 and 5 for example of
rating board-ring card).
When using the rating board-ring card, the interviewer will first read the question. Then
the interviewer will give the ring cards to the respondent and read the first statement.
After that, the interviewer will show the rating board where the respondent can choose
his/her answers from. The interviewer may read the answer categories again and again, if
necessary. She then records the answer of the respondent before proceeding to the next
statement. If the respondent reads everything in the ring cards, the interviewer should tell
the respondent in a polite manner that he/she should answer the questions one by one and
in a particular order. If the respondent understands how to use the rating boards and ring
cards, the interviewer will not have a hard time in the succeeding questions.

shows the language version (in this case, the English version).
Figure 5. Example of a rating board. The board shows the answer categories for an
Agree-Disagree statement battery. The rating board always contains the Filipino
version and the local language version of the answer categories (in this case, the
English version).
6. RELIABILITY ANALYSIS As part of a full review of the survey, questions were subjected to a reliability analysis.
Reliability was measured using Cronbach’s alpha, α. It is a common rule of thumb
that a Cronbach α value of .6 to .7 is an acceptable value. This Technical Report uses
commonly accepted rule of thumb in interpreting Cronbach’s α values:
α ≥ 0.9 Excellent
0.7 ≤ α < 0.9 Good
0.6 ≤ α < 0.7 Acceptable
0.5 ≤ α < 0.6 Below Standard
α < 0.5 Poor
6.1 ECONOMIC EVALUTIONS
The Cronbach’s α value for the six items is .6157, which is considered acceptable. Each
of the six items is positively correlated with each of the other questions in this battery. Q2
(.3375) and Q5 (.3365) have the lowest corrected item-total correlation. Deleting any of
the items from this battery would not have significant effect on the overall Cronbach’s α
value, i.e., none of the items would increase the reliability if they were deleted because all
values are less than the overall reliability α = .615.
Cronbach's α = .615 Corrected Item-total

Q1. How would you rate the overall
economic condition of our country today?.373 .566
Q2. How would you describe the change
in the economic condition of our country
over the last few years?
.337 .579
Q3. What do you think will be the state of
our country’s economic condition a few
years from now?
.349 .588
Q4. As for your own family, how do you
rate the economic situation of your family
today?
.390 .565
Q5. How would you compare the current
economic condition of your family with
what it was a few years ago?
.336 .578
Q6. What do you think the economic
situation of your family will be a few
years from now?
.404 .550
6.2 TRUST IN POLITICAL INSTITUTIONS
The Cronbach’s α value for the 13 items is .837, which is considered good. Each of the 13
items is positively correlated with each of the other questions in this battery. Q7 (.404)
has the lowest corrected item-total correlation. Deleting any of the items from this battery
would not have significant effect on the overall Cronbach’s α value, i.e., none of the items

6.3.1 FAMILY TRUST
The Cronbach’s α value for the three items is .615, which is considered acceptable. Each
of the three items is positively correlated with each of the other questions in this battery.
Q28 (.395) has the lowest corrected item-total correlation. As Q27 has the highest
corrected item-total correlation of .554, deleting Q27 from the battery would have
significant effect on the overall Cronbach’s α value. That is, if it were to be deleted, it
would reduce the overall reliability.615 to unacceptable .398.
Deleting either Q26 or Q28 from this battery would not have significant effect on the
overall Cronbach’s α value, i.e., none of the items would increase the reliability if they

7. EXAMINATION OF REPRESENTATIVENESS OF SAMPLE SET AND WEIGHTING
To yield representative figures at the national level, census-based population weights are
applied to the survey data. The weight projection is computed by dividing the projected
population in the area by the sample size of the same area. Appropriate projected factors
were applied so that original population proportions were reflected in the data tables
using this formula:
Population
Projection factors =-----------------------
(Weight) No. of Interviews
For questions answered by the sample voting-age adults, the following projection factors
were used:
