THE BENEFITS OF SOCIAL NETWORKING PROFESSIONAL GROUPS FOR SALESPERSONS:
SOCIAL CAPITAL & SALESPERSONS
Trang 3Recently social networking professional groups (SNPG) are increasing and becoming popular in various social media sites such as Facebook, LinkedIn, Twitter,
Google+, Pinterest, Forum, and Blog Many people using them as tools to share
information together, acquire existing & new connections, and maintain relationships
Typically, salesperson has demand to connect and maintain with customers every day,
and the SNPG is a very useful tool for them to build up, develop, and nourish
relationships with their business partners By drawing on the social capital theory, there
are three kinds of benefits that salesperson can attain from SNPG, including SNPG
bridging, SNPG bonding, and SNPG maintaining This study attempts to investigate the
effects of these SNPG benefits on salesperson’s self-efficacy, which in turn influence
salespersons performance The data were collected from 120 salespersons, and the result
shows that among the social capital benefits of SNPG, only bringing is positively
associated with self-efficacy of salespersons Besides, self-efficacy of salespersons is
found to significantly increase salespersons performance These findings implies that, in
order to improve salesperson performance, salespersons need to enhance their
self-efficacy, and two sub-dimensions of SNPG bridging can help salespersons enhance this
factor is bridging involvement and bridging devotion

1.1 Research Background
According to We Are Social, a new kind of globe agency combines an innate understanding of social media with digital, public relation, and marketing skills, entirely
focused on innovative, creative and effective social media marketing and
communications Following this agency’s report of South East Asia (SEA) consist of
Vietnam in January, 2014: SEA has nearly 196 million internet users with 31% Internet
Penetration and nearly 162 active social networks users with 26% social networking
penetration (Kemp, 2014)
For further details, Internet Live Stats (2014) show a report: there are about 40 million internet users in Vietnam as of July 01st , 2014 Internet users grow 9% compare
with 2013 in the same period And internet penetration shares 1.28% country’s share of
World Internet Users, and ranges at No.14 of Global rank And We Are Social has just
updated the report of Vietnam in Jan , 2014 significant social indicators: social media
penetration as of percentage of the total population is 38%, the average time that internet
users spend using the internet each day through all devices: 6 hours and 20 minutes
While, the average time social media users spend on social media each day: 2hours and
23 minutes Specially, report also represent Vietnam situation in social media use: 97%
of Vietnam internet users have any social network’s account: Facebook, Google+,
Twitter, LinkedIn, Pinterest and 81% all of them use one of these social network in the
Trang 9previous month With the more detail in percentage of social media usage: 67%
Facebook, 34% Google+, 16% Twitter, 8% LinkedIn, 5% Pinterest Kemp (2014) also
state that: communities or social networking professional groups (SNPG): we can
categorise audience in the common group by instead, look for the interests, motivations
and attitudes that the people we want to engage have in common, and use these
commonalities to define your audience People are drawn to others whom they feel
affinity for, and when it comes to the borderless internet, this affinity is far more
dependent on passion than it is on place around their shared motivation Currently, in
Vietnam now there are many groups or e-communities in social networking They are
established everyday to invite the new members anytime whom have the common
professional or interests or fan club So that, they can connect together, sharing
experiences, new things or interesting topic
From this report, we observe Vietnam internet user, typically the benefits of social network is very large The development of social networking in Vietnam very fast which
make many organizations cannot overlook this opportunity This is the big chance for
salespersons whom need to connect people, customer engagement, building new
customer, approach new prospect or maintain relationship with customer for building
customer service or simply for product warranty or new product introduction
However, in order to understand in-depth SNPG in Vietnam, salesperson need to know what people think and feel when joining these professional groups Furthers detail,
Trang 10salesperson need to understand what factor impact to salesperson when participate SNPG
and from this salesperson can enhance their skill and improving their working
performance when using SNPG
1.2 Research Problems
SNPG in Facebook, Twitter, LinkedIn, Google Plus, Pinterest, Forum, Blog… are becoming an indispensable part of every societies, with many people using them as tools
to share information together, acquire existing & new connections, maintain relationships
online & offline SNPG not only facilitate individuals to connect together but also allow
business organizations to find-out more customers and help generate new customers,
identify potential customers, build customer relationship effectively, and even solve
customer complaints on time As salespersons playing the role of boundary-spanners in
business organizations, they can utilize SNPG for both personal and professional
purposes which might improve the quality of their lives, and enhance their working
capacity, thus leading to better performance in their job
Besides, the reason of joining of salespersons in SNPG from different reasons, for instance, customer service for customer orientation, attracts and finding new customers,
while company think about their business, do some marketing campaign and public
relation activities to pose on SNPG Depending on particular purposes and objectives,
each subject will develop their account in right way
Trang 11According to social capital theory, SNPG bring three kinds of benefits including SNPG bridging, SNPG bonding, and SNPG maintaining to the users within the networks
(Ellison et al, 2007) The benefits or values of SNPG are perceived as supportive among
salespersons upon their joining the groups (Madanka et al, 2013) A comprehensive and
intensive literature review on the application of social capital theory reveals that there is a
lack of research that apply the theory in online environment, especially so far no research
has been done on explaining the benefits and values that salesperson attain from SNPG to
improve their working performance Therefore, the purpose of the current research thesis
is to investigate the relationships mechanism that three aforementioned benefits of social
capital (i.e., SNPG Bridging , SNPG Bonding, and SNPG Maintaining) pertaining to
Salespersons Performance and Self-Efficacy of Salespersons at work
1.3 Research Objectives
The overall objective of this study is to examine SNPG benefits to Salespersons performance Typically, it investigates:
The relationship between SNPG Bridging and Self-Efficacy of Salespersons
The relationship between SNPG Bonding and Self-Efficacy of Salespersons
The relationship between SNPG Maintaining and Self-Efficacy of Salespersons
The relationship between Self-Efficacy of Salespersons and Salespersons
Performance
1.4 Research Methodology and Scopes
Trang 12The research method that many researchers are using lately is the combination of qualitative and quantitative research It helps increase the accuracy and sufficiency of the
study Applying qualitative research to collect the ideas and opinions allows the
adjustment of the study is made While, the quantitative research guarantees many people
take the survey and allows the researcher to carry out the data analysis with more reliable
results
The researcher uses Statistical Package for the Social Science software (SPSS), an effective tool to analyze the data The first step is to study the Descriptive Statistics The
second one is to test the reliability of the scales (Cronbach’s Alpha), Factor Analysis
Finally, the Regression is used to examine the relationship between independents
variables and dependent variables
This study is to research salespersons performance in SNPG in Vietnam, so, the scope of this research is restricted to all salespersons who mostly live in Hanoi City and
Ho Chi Minh City Because these cities are the two biggest city of Vietnam with the huge
number of population, have modern technology and stable infrastructure, people who are
living in these areas have better facilities to access social networking sites than other
people in other areas Certainly, the respondents of this study must know about SNPG
and have created an account on it; otherwise, their answers are not qualified and cannot
be used in the data analysis

Trang 14This chapter presents main conclusions and implications based on the results of the previous chapters, some suggestions for the improvement as well as the limitations of
this study
CHAPTER 2: LITERATURE REVIEW & HYPOTHESIS DEVELOPMENT
In this chapter, researcher presents the literature review, the research model and the hypotheses development of the study
2.1 Social Networking Professional Groups (SNPG)
According Scoot & Johnson (2005) SNPG or e-communities are defined as groups
of people with common interests that communicate regularly, and for some duration, in
an organized way over the Internet, they are designed to provide users with a range of
tools for learning, personal development, and collective action point, all embedded in a
complex, continuing, and personally enriching network of social relations And Pinho
(2013) state that SNPG (e.g Facebook, Twitter, Linkedln and Pinterest) have become a
recent global phenomenon in human communication and interaction, more than a billion
individuals are globally connected through virtual communities, interacting with their
friends and working partners, exchanging valuable knowledge while being exposed to a
vast universe of brands SNPG are becoming an indispensable part of every societies,
with many people using them as tools to share information together, acquire existing &
new connections, maintain relationships online & offline, all of them have target users
and separately benefits differently
2.2 Social Capital: Bridging, Bonding, and Maintaining
Trang 15According to social capital theory, the term “social capital” is what allows any organization or individual to make requests of its followers successfully, think of social
capital as funds in a sort of intangible bank account that you add to by listening to,
engaging with, and doing favors for others (Solomon, 2013)
Huvila et al (2009) also declare social capital has been acknowledged as it opens
up relational, structural and content dimensions related to sharing Social capital refers to
both norms and networks as facilitating collective action and encouraging cooperative
behavior, the positive effects of having a high level of social capital through networks
and through the relationships between individuals and social units Social Capital, a
method to measuring the value of connections that resident have to each other and to their
communities (Frank, 2010)
Madanka et al (2013) define social capital is crucial & vital ingredient of economic included: social supporting, integration, social cohesion, teamwork, density of
changes with colleagues Adler & Kwon (2002) also define social capital is the goodwill
available to individuals or groups Its source lies in the structure and content of the
actor’s social relations Its effects flow from the information, influence and solidarity it
makes available to others
Jones (1987) explained supporting of SNPG: Perceptions of their social network support, self-esteem, time of study participation, and motivation for using social networks
(e.g., to find new friends, new customers, to share good or bad things, to obtain new
Trang 16information) interacted with SNPG use to predict changes in affective or cognitive
well-being or self-efficacy
Social capital help people to share of social networking, reduced probability of opportunism, cost of monitoring, encourage cooperative behavior, facilitating
development of new form & innovative organization, taking advantages of new
opportunities, featuring the structure, not of individual actor within social structure,
ecologic characteristic (Madanka et al, 2013) There is relation between supporting of
SNPG, interest in media such as: Internet, computer games, video games, computer, cell
phone, and television and personal’s well-being (Castella et al, 2011) And help
individual becoming strong, consistent, reciprocity, provide info people care abt, positive
way to bring benefit to someone, ask for opinion, giving back, reputation, value
contructive input, more controversial , to be involved, giving credit, encourage feedback
(Solomon, 2010)
Ellison et al (2007) state that social capital brings three kind benefits of SNPG:
including SNPG bridging, SNPG bonding, and SNPG maintaining to the users within the
networks and distinguishes between bridging and bonding social capital The former is
linked to what network researchers refer to as ‘‘weak ties,’’ which are loose connections
between individuals who may provide useful information or new perspectives for one
another but typically not emotional support (Granovetter, 1982)
2.3 Self-Efficacy of Salespersons
Trang 17Based on research of Chelariu & Rodney (2011), Salesperson self-efficacy refers
to judgments about the individual’s capability to organize and execute courses of action
required to achieve designated levels of sales performance (Bandura, 1978) Self-efficacy
is not concerned with the skills one has, but with the judgment of what one can do with
whatever skills one possesses (Bandura,1986) From a cultural standpoint, self-efficacy is
often seen as being congruent with traditional Western values such as mastery,
self-reliance, and achievement (Gecas, 1989)
Sujan et al (1994) define self-efficacy is domain specific, it is a more general construct than expectancy, which involves success at specific sales tasks, but a narrower
construct than esteem, which refers to success in all life’s domains Strong
self-efficacy beliefs have been consistently associated with task performance or high levels of
sales performance in general (Ryerson, 2003) Sujan et al (1994) state that: performance
orientation motivates both “working hard” and “working smart” more so for high
self-efficacious salespeople than for those who are less self-self-efficacious Self-efficacy is
defined as how well one can execute courses of action required in dealing with different
situations
Self-Efficacy, establishing the foundation, can be credited as the foremost theorist
in the area o f self-efficacy His original work originated from social In simplifying the
definition of self-efficacy, Bandura (1986) propose that an appropriate measure is not o f
the skills one possesses but of the judgment of, “ what one can do with whatever skills
one possesses” (Ryerson, 2003)
Trang 18The benefits or values of SNPG are perceived as supportive among salespersons upon their joining the networks (Madanka et al, 2013) Such is associated to improve
their professional knowledge and skills (Solomon, 2010), enable them to develop more
contacts and build relationships with both extant and potential customers (Jones, 1987),
thus enhancing their self-efficacy at work (Chelariu & Rodney, 2011), then eventually
leading to a better sales performance in their job (Sujan, 1994)
There are two types of social capital: bridging and bonding Putnam (2000)
“Bridging social capital” is accommodative It occurs in social networks linking
individuals of different backgrounds, providing opportunities for the exchange of
new information or resources Bridging social capital “is better for linkage to external
assets and for information diffusion” Putnam (2000) In the other words, bonding social
capital ensures a sense of social solidarity within groups, while bridging social capital
links often disparate people and provides information about opportunities outside the
groups
Based on this prior work, we proposed the following hypothesis having relation between Social Capital: SPNG Bridging and Self-Efficacy of Salespersons:
H1: SNPG bridging is positively associated with Self-Efficacy of Salespersons
Putnam (2000) also state that “bonding social capital” can be monopolized It occurs among personal acquaintances such as family members or close friends
who provide mutual support for one another, both emotionally and physically The
diversity of these social bonds and social capital is the result of strong interpersonal
Trang 19connections “Bonding social capital is good for under-girding specific reciprocity and
mobilizing solidarity”,
Patulny & Svendsen (2007) claim the beneficial outcomes that flow from bonding social capital, such as reduced transaction costs among familiars, focuses upon secure
closed networks, in that special interest groups can cooperate to impose costs on
non-members in pursuit of member’s interests, the gains being much greater in this regard
than from cooperative action
Meadowcroft & Pennington (2008) define bonding social capital describes the cohesion that exists between small groups of similar people, such as family members,
close friends, and colleagues and perhaps the members of ethnic or religious groups, the
bridging variety describes the networks that link acquaintances who may be very
dissimilar people, such as businesswoman and her customers
These arguments lead to following hypothesis:
H2: SNPG bonding is positively associated with Self-Efficacy of Salespersons
Alternatively, bonding social capital is found between individuals in tightly-knit, emotionally close relationships, such as family and close friends After briefly describing
the extant literature on these two forms of social capital and the Internet, we introduce an
additional dimension of social capital that speaks to the ability to maintain valuable
connections as one progresses through life changes This concept, ‘‘maintaining social
capital,’’ permits us to explore whether online network tools enable individuals to keep in
touch with a social network professional groups (Ellison et al, 2007)
Trang 20Penard and Poussing, (2010) state that: interesting relations between participatory online capital, a high level of trust in others increases the probability of maintaining
social capital through the Internet
Based on this prior work, we proposed the following hypothesis having relation
between SPNG Maintaining and Self-Efficacy of Salespersons:
H3: SNPG maintaining is positively associated with Self-Efficacy of Salespersons
2.4 Salespersons Performance
Barling & Beattie (1983) stated a correlation between self-efficacy beliefs and salespersons performance The generality of self-efficacy theory in a business
environment was indicated by the relationship between self-efficacy and objective
measures of sales performance Self-efficacy theory postulates that people will perform
better when they believe that they have the skills necessary to succeed
The definition for salespersons performance borrowed from (Michael, 2010) study
of sales performance evaluation Measures include presentation skills, product
knowledge, customer relations, as well as quantity o f sales The sales behaviors of sales
professionals are defined as actual assessments of what psychological and physiological
behaviors the sales professionals carry out (Anderson & Oliver, 1987)
General self-efficacy impacts on sales performance has been researched and measured the positive relationship between self-efficacy of performance rating and sales
performance, with mixed results as to the correlation between self-efficacy and
salespersons performance (Lee and Gillen 1989)
Trang 21Krishnan et al (2002) state that: the individual characteristics of self-efficacy, competitiveness, and effort as potential antecedents of salesperson performance Based
on different selling contexts, it is observed that whereas effort mediates the relationship
between competitiveness and sales performance, self-efficacy has both direct and indirect
effects on sales performance
Based on this prior work, we proposed the following hypothesis having relation between Self-Efficacy of Salespersons and Salespersons Performance
H4: Self-Efficacy of Salespersons is positively associated with Salespersons
Performance

3.2.1 Measures of Social Capital
Measures of social capital—Bridging, Bonding, and Maintaining —were created
by adapting existing scales, with wording changed to reflect the context of the study, and
creating new items designed to capture Internet-specific social capital (Ellison et al,
2007) The factors of social capital analyzed to ensure that the items reflected three
distinct dimensions:
SNPG Bridging
Bridging1: I feel I am part of the SNPG
Bridging2: I am interested in what goes on at SNPG
Bridging3: SNPG is a good place to be
Bridging4 I would be willing to contribute money to SNPG
Bridging5 Interacting with people at SNPG makes me want to try new things
Bridging6 I am willing to spend time to support general social media activities
Bridging7 At SNPG, I come into contact with new people all the time
Bridging8: Interacting with people at SNPG reminds me that everyone in the world is
connected
SNPG Bonding
Bonding1: There are several people at SNPG I trust to solve my problems
Bonding2: There is someone at SNPG I can turn to for advice about making very
Trang 25important decisions
Bonding3: The people I interact with at SNPG would be good job references for me
SNPG Maintaining
Maintaining1: I’d be able to find out about events in another town from SNPG
acquaintance living there
Maintainging2: I’d be able to stay with SNPG acquaintance if traveling to a different city
Maintaining3: I would be able to find information about a job or internship from a SNPG
acquaintance
Maintaining4: It would be easy to find people to invite to SNPG reunion
3.2.2 Measures of Self-Efficacy of Salespersons
Self-Efficacy of Salespersons
Measure of Self-Efficacy of Salespersons was created by adapting existing scales from (Chelariu and Stump, 2011):
Self-Efficacy1: It’s easy for me to make my customers understand me
Self-Efficacy2: I am confident of my ability to sell
Self-Efficacy3: I feel I have the capabilities to successfully perform well in my job
Sefl-Efficacy4: I am good at selling
3.2.3 Measures of Salespersons Performance
Salespersons Performance
Trang 26Measure of Sales Performance was created by adapting existing scale from (Frino, 2010):
Sales Performance1: Grade your selling skills
Sales Performance2: Your overall performance in terms of quantity of sales achieved?
Sales Performance3: Your overall performance in last year?
Sales Performance4: Where do you rank currently in the sales organization?
3.3 Data Collection Method
The primary data is mainly collected by sending email to salespersons through researcher’s email Most of them is doing business in sales jobs and they are belong
researcher’s networking from: customers, partners, suppliers, colleagues, and friend
Posting on Facebook and LinkedIn of researcher to invite salespersons to response
questionnaire list using Google Form
Sampling design
Salespersons
Salespersons for this study is Vietnamese salespersons who have been working sales area included B2C & B2B company, in HCMC, Hanoi City consist of: Sales Staff,
Sales Executive, Sales Manager, Sales Director and Private Owner
Sample size and Sampling Method
Preliminarily, the sample size for this study should be 200 people, the convenient sampling was also applied to increase the attendant probability in the survey and to
Trang 27possibly get around 150 - 180 results in return but due to time limit, it was not easy to
reach that number The researcher received 133 questionnaires after several times of
sending the questionnaire to above 200 people including reminders In which, there were
7 respondents had no account social networking sites, they must be cleaned and 6
questionnaires lack of reliability are all given answer as “neutral” must be deleted
According to Hair et al (2006), “it is generally agreed that the minimum sample for appropriate use for statistical analysis is equal to or greater than 5 times of
independent variables, but not less than 100”:
n ≥ 100 and n ≥ 5k (where k is equal to the number of variables)
In this study, there are 23 variables, so the minimum sample size for this research is:
n = 5 x 23 = 115 (k = the number of variables)
Otherwise, Tabachnick and Fidell (2001) illustrated the minimum sample size, which is required for the multiple regressions analysis should be:
n ≥ 50 + 8m (where m is equal to the number of independent factors)
In this study, there are three independent factors, so the minimum sample size is required for the multiple regressions:
n = 50 + (8 x 3) = 74 (m = 3 is the number of independent factors)
Finally, 120 questionnaires remaining after cleaning all unqualified answers were possible for running data analysis
3.4 Qualitative Research
Trang 28It is important to carry out qualitative research for the brainstorming and summarizes knowledge The researcher has to acknowledge all factors and explain their meaning in the
easiest way to be able to understand by most of people for having the precise results then
establish four hypotheses for the study After achieving the measurement scale borrowed
from others, the researcher had to modify and design into preliminary scale to be suitable for
the topic of this study
Creating the first questionnaire based on the preliminary scale when conducting the in-depth interview with a group of targeted salespersons who frequently use internet for sales
job Typically, usually participate in SNPG to engage with customers and others The
researcher interviewed salespersons to know if they can understand the scale and explore
other opinions or suggestions for the improvement of official questionnaire While collected
data, respondents also feedback and called back researcher to advise opinion to adjust
questionnaire list appropriately This step allowed the researcher supplementing and
adjusting the questionnaire (See Appendix A)
The researcher modified the questionnaire according to the reviewing of comments and ideas or suggestions from those interviewees The questionnaire was structured into 3
parts for screening and classifying The first part is for screening, the respondents must know
about SNPG and used to login frequently The second part was the main part of the research
which focused on salespersons of factors associated with self-efficacy and salespersons
performance The third part was to classify demographic data such as gender, age, education
and employment However, it was written in English while the study was carried out within
Trang 29Vietnam with Vietnamese people, so, before giving to the respondents, the researcher
translated it into Vietnamese (See Appendix B)
At that moment, the revised questionnaire was used for 20 pretest first This test was needed to know whether people can understand each question or misunderstand some things
or not To check the contents and meaning of the words, there were salespersons already took
this test In this stage, if anyone had other ideas or could not get it, the questionnaire had to
be corrected again Fortunately, all of them committed to ans agreement that every question
was easy to understand and there were nothing cause confusions After all, the final
questionnaire was officially completed
3.5 Quantitative research
Since collecting data as many as possible are necessary and the key point of the quantitative method, the official questionnaire was finished earlier must be issued widely for
the coming process
When the main research started, the first thing was to fix the time of recalling questionnaire
results All of information must be in hand of the researcher within 3-4 weeks since the
starting day of sending questionnaire The questionnaire of this research was delivered to the
respondents in early of August, 2014
In the condition of time limit, the communication method through email was reasonable and better Sending email will save time and cost and makes the respondents feel
comfortable to answer the questions Collecting data through email took long time, so, twice
to three times or more reminders to the recipients helped increase the responses, in this
Trang 30situation, the reminder happened every 02 days Posting the link of the survey on Facebook
was a good way because its wide and convenient network helped collecting very quickly and
four other members of Facebook also gave a hand to share that link to their contacts
Following the details of data cleaning, the errors including unqualified respondents and lack
of reliability were removed turned the final sample to 120 observations
3.6 Data Analyzing Method
The specific processes of data analysis will be declared in the next section This part only presents the encoding of the data with the scale

SalesPerformance3, SalesPerformance4
All the data was analyzed by the Statistical Package for the Social Science (SPSS) 16
Firstly, the descriptive statistic helped figure out the characteristics of the sample After that,
by using Cronbach’s alpha measurement and Exploratory Factor Analysis, the reliability of
Trang 31factors was tested and the conceptual model was assessed and modified For more
specifically, Cronbach’s alpha is the most commonly used in internal consistency reliability
testing which is above 0.6 and the higher, the more reliable Also, EFA is used when
developing scale and to identify underlying relationship between measured variables
Normally, the number of factors is less than the numbers of measures, therefore, a factor
must represent a set of measures and at least three to five measures per factor for the
accuracy Finally, Multiple Regression was conducted to test the relationship between
independent and dependent variables to come up with an equation
Trang 32CHAPTER 4: DATA ANALYSIS and RESULTS
In this chapter, researcher will test Reliability of Scale by: Testing Cronbach’s Alpha and EFA After testing, Cronbach’s Alpha EFA, researcher will running multiple
regression analysis
After cleaning data, we collected total 120 respondents from salespersons joined to answered this survey through email, posting on personal Facebook and LinkedIn, some of
them researcher also posted in popular group of Buy-Sell Online on Facebook, LinkedIn
and others Forum to targeted the salespersons such as: otosaigon.com,
webtretho.com…etc… to capture almost salespersons there There are 95% respondents
used to use professional group in social networking sites and 5% do not use any social
networking profession groups (SPGs) And there is 84.09% salespersons using Facebook,
33.33% salespersons using Forum, 23.48% salespersons using LinkedIn, 16.67%
salespersons using Google Plus, a few salespersons using Twitter and Pinterest are not
much familiar in Vietnam with the same 4.55%, 15.91% salespersons using Blog and
remain 1.52% salespersons using others professional groups in social networking
websites
Trang 33Figure 4.1 Statistic using SNPG of Salespersons
According below Table 4.1 & Figure 4.2 to show how of salespersons using social networking profession groups frequently, there is 48% salespersons using it frequently
and only 3% dit not using it frequently

Trang 354.2 Reliability Analysis: Cronbach’s Alpha Testing
Cronbach’s coefficient alpha was used to test the reliability of the measurement scales The value of Cronbach’s alpha need to be accepted is over 0.6 and any variables
which the Item-total correlation are smaller than 0.3, negative and the lowest value will
be considered to delete from factor
SNPG Bridging factor

reliability of Bridging factor
We tested again and Reliability Statistics is better at 0.834 See results detail in Appendix C

Trang 38We found item: Maintaining2 have the lowest Corrected Item is 0.446, if we remove this item then cannot help Cronbach’s Alpha (0.71 > 0.6) of Maintaining factor is
higher even lower at 0.675 So all of these 04 items should be keep for next EFA testing

Self-Efficacy is measured by 04 items and having Cronbach’s Alpha is 0.824 >
0.6 And we found in Table 4.8: Self-Efficacy1 have the lowest Corrected Item- Total
Correlation is 0.536, however deleting this item raise more reliability very little at 0.828,
the difference is 0.004- too small Therefore, we still keep it for next EFA testing to see
what happen

Trang 404.3 Exploratory Factor Analysis
For this study, Exploratory factor analysis (EFA) is conducted to analyze validity
At the beginning, this study has defined 23 independent variables affecting to
salespersons After tow variables consist of Bonding3 and Bridging4 had been deleted
because of the low Item-total correlation through reliability analysis, 21 variables were
used to run EFA analysis We will run EFA for all variables together, including both
independent factors and dependent factor If there are some variables appear in 02 or
more than 02 components, then it should be considered to delete for better result in EFA
analysis
4.3.1 Factor Analysis
The KMO’s value is 0.862, means the data set is likely to factor well and Bartlett’s test shows the significant value lower than 0.05 (Sig =.000) which indicating that the
correlation matrix is significant different from an identity matrix and the correlation
between variables are all zero As result, both acceptances for diagnostic tests confirm
that the data are suitable for factor analysis
