    THE RELATIONSHIP BETWEEN BANKING SERVICE QUALITY AND

    CUSTOMER SATISFACTION IN COMMERCIAL BANKS IN THUA THIEN

    HUE PROVINCE VIET NAM: THE TEST ON STRUCTURAL EQUATION

    MODELING (SEM)

    ABSTRACT

    This study aims to identify the relationship between service quality and customer satisfaction in commercial banks in Thua Thien Hue on the basis of a survey conducted from 439 customers. Adjusted SERVPERF model; reliability Cronbachs Alpha analysis, exploratory factor analysis (EFA), confirmatory factor analysis (CFA) and structural equation modeling analysis (SEM) are the principal data analysis methods in this study.

    The research result has shown that the quality of banking services is measured by six components which are shown in order of importance to positive effect on customer satisfaction, including Reliability about service delivery process (RELI), Assurance (ASS), Tangibles (TAN), Reliability about promise to customer (RELII), Empathy (EMP) and Responsiveness (RES).

    Keywords: Thua Thien Hue; Relationship; Service quality; Satisfaction. 1. Introduction In the current business environment which is constantly changing and contains intense competition, commercial banks are facing with many challenges. One of the biggest challenges is competitiveness. When competitive pressures increase, service quality is considered as a competitive factor of the banks and it is also considered as an essential key to create the difference among banks (Kazi Omar, 2011). So, delivering service quality system accordant with customer demand is considered as one of the crucial ways that could create competitiveness and sustainable competitive advantages for banks. To assess the suitability of banking service quality to the customers needs, customer satisfaction on service quality is an important measure. And satisfying customers has become an important asset for the banks in an effort to improve service quality, which will enhance the banks competitiveness [8], [12]. So far, there are many studies about the relationship between banking service quality and customer satisfaction in the world such as Levesque study, McDougall (1996); Almad Jamal, Kamal Naser (2002) and Addo Kwarteng (2012). In Vietnam, Dinh Phi Ho (2009, 2012); Gioi & Huy (2012) have studies in a number of local banks (Ho Chi Minh City, Da Nang). These studies have mentioned and clarified this relationship in different banks. Although these studies have a number of different points (components affecting quality of banking services and the relationship between these components and customer satisfaction) due to different characteristics of customer behavior in each locality, research locations, but in general, these studies showed significant relationship between service quality and customer satisfaction in the bank.

    Reality shows that this significant research issue is quite limited in Thua Thien Hue. Therefore, the study of the relationship between service quality and customer satisfaction in the banking sector is very essential.

    This article will focus on identifying the components of the banking service quality and the extent of its impact on customer satisfaction through the case studies in commercial banks in Thua Thien Hue. 2. Literature review and research model

    2.1 Service quality The conceptualization and measurement of service quality is one of the most

    debated topics in service marketing literature (Brady and Cronin, 2001). There are many of different definitions about service quality. Here, some important definitions of service quality are coming as following:

    Service quality is determined by the differences between customers expectations of services providers performance and their evaluation of the services they received (Parasuraman et al., 1985, 1988). Service quality is the consumer's judgment about an entity's overall excellence or superiority; it is a form of attitude, and results from a comparison of expectations to perceptions of performance received (Zeithaml, 1987). Or service quality can be defined as the difference between customers expectations for service performance prior to the service encounter and their perceptions of the service received (Asubonteng et al., 1996). Generally, the authors described service quality as a form of attitude that results from the comparison of consumer expectations with service performance delivered.

    As we have known, service is intangible, heterogenic, and inseparable, which makes service quality difficult to measure and understand (Parasuraman et al., 1985).

    Many researchers tried to define and measure service quality for a long time. The result is there are many instruments to measure. Among instruments, the most popular model used for evaluation of service quality is SERVQUAL, a well-known scale developed by Parasuraman et al. (1985, 1988).

    Parasuraman et al. (1988) developed and tested the five components scale of the service quality, called SERVQUAL scale, consisting of 22 variables to measure five components of service quality, which are: reliability, responsiveness, assurance, empathy and tangibles.

    The measurement model that Parasuraman et al. (1988) suggested still has controversy by many scholars around the world. In the framework of this debate, Cronin and Taylor (1992) stated that service quality can be generalized to a similar viewpoint, attitude. They announced a model that only mentions the performance instead of performance minus expectation" (SERVQUAL) to measure service quality. This model is called SERVPERF (Service performance).

    When using the SERVQUAL model, respondents expressed confusion when answering questions twice on the expected and perceived versions (Bouman & Van der Wiele, 1992). In addition to the long questionnaire, the expectation concept is also vague for the respondents (Phong & Thuy, 2007). Therefore, using SERVPERF model will get better result than SERVQUAL. SERVPERF model questionnaire is also brief more than half compared to SERVQUALs, which will enhance willingness for answering questionnaires from respondents.

    Therefore, our research approaches how to assess the service quality by performance (SERVPERF scale) by Cronin and Taylor (1992). 2.2 Customer satisfaction

    Customer satisfaction is considered as the foundation of the marketing concept on satisfying needs and wants of consumers (Spreng, MacKenzie, & Olshavsky, 1996). There are many definitions of customer satisfaction. For example:

    Customer satisfaction is defined as an "evaluation of the perceived discrepancy between prior expectations and the actual performance of the product" (Tse and Wilton, 1988).

    Satisfaction is the reaction of the customer when meeting the want (Oliver, 1997)

  • 4

    Customer satisfaction is the degree of a person's state of feeling derived from comparison of results obtained from consuming products/services with his expectation. Satisfaction level depends on the difference between getting results and expectations, if actual results are lower than expected, the customer is not satisfied, if the actual results match the expectations, the customer will be satisfied , if actual results are higher than expected, the customer is very satisfied (Kotler, 2002).

    Thus, satisfaction is a function of the difference between getting results and expectations (Kotler, 2003). 2.3. The relationship between service quality and customer satisfaction

    The relationship between service quality and customer satisfaction is the topic has been discussed consecutively in the last decades. Many studies have attempted to establish the essence of the relationship between service quality and customer satisfaction (Jamal & Naser, 2002). Among them, a number of studies have shown a causal linkage between satisfaction and service quality (Jamal & Naser, 2002).

    Many studies on customer satisfaction in the service sector have been made (Fornell, 1992) and have generally concluded that service quality and satisfaction are two distinct concepts (Bitner, 1990; Boulding et al, 1993).

    Service quality and satisfaction are two different concepts but are closely related to each other in studying about service (Parasuraman et al, 1988). According to some previous studies in other countries around the world and in Vietnam, the relationship between these two concepts has been clarified from the supermarket industry (Dabholkar, 1996; Tho & Trang, 2006; Phong & Thuy, 2007), Hotel (Mahdavinia, 2007; Giao & Hao, 2011; Huy & Quang, 2012) to the banking sector (Levesque & McDougall, 1996; Almad Jamal & Kamal Naser, 2002; Najjar & Bishu, 2006; Dhandabani, 2010; Siddiqi, 2011; Addo &Kwarteng, 2012; Dinh Phi Ho, 2009, 2012; Giao, 2010, 2011; Gioi & Huy, 2012). In summary, these studies have shown the existence of a positive relationship between components of service quality and customer satisfaction with different levels depending on each service sectors characteristics. Therefore, it can be confirmed that the quality of service is the cause of customer satisfaction. The reason is that quality is related to service delivery, and satisfaction can be only assessed after using the service. If quality is improved, but not based on the needs of the customer, the customer will never be satisfied with the service. Hence, when using services, if customers feel high-quality services, they will be satisfied with the service. Conversely, if customers feel low-quality services, dissatisfaction will appear.

    On the basis of theoretical research on criteria of evaluating the service quality and the relationship between service quality and customer satisfaction above, along with the characteristics of the banking sector, the proposed research model is shown in Figure 1.

    service. Assurance (ASS): The knowledge and courtesy of employees and their ability

    to convey trust and confidence. Empathy (EMP): The provision of caring, individualized attention to

    customers. Tangibles (TAN): The appearance of physical facilities, equipment, personnel,

    and communication materials. 3. Research methodology To achieve the research objectives, the study was carried out with process consists of two steps: (1) pilot study, and (2) main study. 3.1. Pilot study

    * Secondary data: the researchers gathered information from books, newspapers, textbooks, internet, specialized scientific journals related to service quality and customer satisfaction.

    * Qualitative pilot study: Qualitative pilot study was conducted through discussions with experts and customers. First, discussions with experts was conducted through in-depth interviews with senior managers of commercial banks in Hue. This was followed by group discussions with 20 customers regularly using banking services. The main purpose of this study step is to explore, adjust or edit the banking service quality and customer satisfaction scales.

    Based on the theoretical basis from secondary materials combined with discussions with experts and customers, the designed questionaire consists of 02 parts, part I: information about answered subjects, part II: measurement of banking service quality and customer satisfaction. This section is designed to include 29 observed variables. In particular, the first 26 observed variables used to measure service quality according to Servperf model, 03 next observed variables used to measure customer satisfaction1. Each observed variable is measured based on the 5-point Likert scales, from completely disagree (strongly disagree) to completely agree (strongly agree).

    * Quantitative pilot study: Quantitative pilot study was conducted through pre-interview with customers to complete questionnaires for the survey process. 3.2. Main study

    Main study was carried out by quantitative research methods. To perform the study, we conducted a sample survey through direct interviews customers of commercial banks with questionaires to collect data.

    Because the data analysis methods used in this study based on analysis of linear structural model SEM, to achieve reliable estimates for this method, sample

    1 Based on the study of Lassar et al. (2000), the scale of customer satisfaction includes 03 observed variables: Satisfied with the quality of banking services (SAT1), About the bank's services to others (SAT2), Continue to use the bank's services in the future (SAT3).

    size is often large (n> 200: Hoelter, 1983). On the other hand, based on the experience rule (Bollen, 1989), it requires at least 5 samples for a estimated parameter. Hence, following the above, based on the number of parameters to be estimated, the sample size targetted in this study was more than 400.

    Sample was selected by convenience sampling method of size n = 500. Thus, 500 questionnaires were given out, 456 collected, reaches 91.2%. In 456 collected questionnaires, there was 17 questionnaires did not meet requirements due to missing information were rejected. Finally, 439 questionnaires were used in the analysis.

    Data collected from 439 questionnaires corresponding to 439 surveyed customers were entered and processed on SPSS, AMOS software with using analytical techniques such as: descriptive statistics, testing the reliability of a scale by Cronbach's coefficient alpha, explore factor analysis (EFA), confirmatory factor analysis, structural equation modeling analysis. 4.

    Regarding career, surveyed customers are mainly white-collar employee and businessman accounting for 64.2% of the sample size; followed by students accounting for 18.3%, 11.8% of retirement; the remaining is the other labor.

    Regarding bank of transaction, proportion of bank customers surveyed in the sample is distributed fairly equally ranging from 10 to 12.1%. 4.2. Reliability analysis

    Table 2 shows the Cronbach's Alpha coefficients of all scales are larger than 0.6 and the totals correlation coefficient of corrected items are greater than 0.3.

    According to Nunnally and Burnstein (1994), selection criteria of Cronbach's Alpha is higher than 0.6 and the total correlation coefficient is higher than 0.3. Therefore, this result can conclude that all scales achieved reliability and used for subsequent analysis of EFA. Table 2: Cronbachs Alpha testing result of service quality and satisfaction scales

    To use factor analysis techniques, we must consider the appropriateness of factor analysis. Keiser-Meyer-Olkin (KMO) measure of sampling adequacy and Bartlett's Test of Sphericity are the indexes used to consider that appropriateness. If KMO index is in the range from 0.5 to 1 and the Bartlett test has the value Sig. < 2, the factor analysis is considered appropriate [20]. KMO test results and Bartlett's Test for the scale of quality banking services show that the database is fully suitable for factor analysis because the KMO index reaches 0.843 and Bartletts test has statistical significance (Sig. = 0.000 1, variance extracted is 50.311%; all itemfactor loadings are simultaneously above 0.5.

    After testing the scale by Cronbach's alpha coefficient and EFA, we have the modified model shown in Figure 2.

    4.4. Confirmatory Factor Analysis (CFA) In the CFA analysis, we can carry out for each concept, several concepts, or all

    concepts included in the model (called the critical model). Here, the concepts are level one concept so CFA analysis should be done for all concepts in the model.

    Confirmatory Factor Analysis CFA was conducted with 29 observed variables. From the analysis, 6 EFA factors are extracted to service quality scale and 1 factor is extracted to the satisfaction scale. These factors create corresponding scale groups forming concept measurement models and taken into CFA analysis to consider the appropriateness of the model to market data.

    To assess the scale by Confirmatory Factor Analysis (Confirmatory Factor Analysis - CFA), the research group used Chi - square criteria adjusted by degrees of freedom (Cmin / df), the Comparative fit index (CFI), the Tucker and Lewis index (TLI) and the Root Mean Square Error approximation (RMSEA).

    If a model has TLI, CFI 0.9 (Bentler & Bonett, 1980), CMIIN / df 3 (Carmines & McIver, 1981), RMSEA 0.08 (Steiger, 1990), the model is considered to be consistent with market data.

    Five scale evaluation criteria include: (1) Composite Reliability, (2) Variance Extracted, (3) Unidimensionality, (4) Convergent Validity and (5) Discriminant Validity (Hair et al, 2009).

    CFA result of the banking service quality scale model shows that the model has 355 degrees of freedom; Cmin / df = 2.858, TLI = 0.940, CFI = 0.948 and RMSEA = 0.065 should be confirmed the model fits the market data.

    The scale evaluation criteria are shown as follows: (1) Composite Reliability, (2) Variance Extracted: The integrated reliability of the component (concept) Assurance (ASS) is 0.938 with total variance extracted is 75%; of the component (concept) Reliability about service delivery process (RELI) is 0.904 with total variance extracted is 66.3%; of the component (concept) Responsiveness (RES) is 0.875 with variance extracted is 59.5%; of the component (concept) Tangibles is 0955 with variance extracted is 84.2%; of the component (concept) Empathy is 0.844 with variance extracted is 60.4%; of the component (concept)

    Reliability about promise to customer (RELII) is 0.960 with variance extracted is 88.9% and the component (concept) Customer Satisfaction is 0.749 with variance extracted is 50.3%. All coefficients are greater than 0.5 and 50%, satisfy the conditions of integrated reliability and total variance extracted (Fornell & Larcker, 1981 Hair, 1998). (2) Unidimensionality: Figure 1 shows that only component (concept) Empathy (EMP) do not reach unidimensionality because relationship between errors exists (e22 and e23), and other components (concepts) reach unidimensionality. (3) Convergent Validity: Gerbring & Anderson (1988) argues that scale achieves convergent values when weight of standardized scales are high (>0.5) and statistically

    significant (p0.5) and statistically significant with all p-values are equal to 0.000. Therefore, we conclude the observed variables used to measure 6 components of the service quality scale and 1 component of satisfaction scale achieves convergent value. (4) (Discriminant Validity): We found that the correlation coefficients between component concepts are less than 1 (statistically significant), so all concepts of component achieve discriminant validity.

    customer satisfaction (eg, Dinh Phi Ho, 2009, 2012; About & Huy, 2012; Zaim et al, 2010; Mengi, 2009; Kumar et al, 2010; Lai, 2004, Baumann, 2007; Ahmed et al, 2010). In these components which can affect to customer satisfaction, the factor Reliability about service delivery process (RELI) has the strongest effect. This is consistent with some previous studies (eg, Arasli, 2005; Najjar & Bishu, 2006; Jamal & Naser, 2002).

    Currently, customers become busier and their time budget should be distributed to more work so they esteem their time. Therefore, when doing anything, they wish to be precise to help them limit waste of valuable time due to doing improperly. During bank transaction, customers often require theirs to be done correctly, accordantly to help them avoid wasting time due to repeating transactions when wrong.

    Therefore, the study results show the fact that Reliability about service delivery process (RELI) impacts (influences) the most to customer satisfaction is a perfect fit. And, in order to improve customer satisfaction, thereby contributing to maintain relationships with customers, banks need to have oriented solutions from identified components through research results, especially Reliability about service delivery process (RELI). 5. Conclusion and future research suggestions

    Research results have shown that customer satisfaction in the case of commercial banks in Thua Thien Hue affected by service quality components in order of importance, they are: Reliability about service delivery process (RELI), Assurance (ASS), Tangibles (TAN), Reliability about promise to customer (RELII), Empathy (EMP) and Responsiveness (RES). In particular, Reliability about service delivery process (RELI) is the strongest component affects customer satisfaction. On the other hand, the results obtained from the analysis of structural equation modeling, it was found that 06 components of quality banking services explain only 61.3% of customer satisfaction; the remaining 38.7% is due to impact from other components.

    Hence, in order to improve customer satisfaction, the commercial banks in Thua Thien Hue needs to focus on improving the banking service quality component, including components Reliability about service delivery process (RELI), Assurance (ASS), Tangibles (TAN), Reliability about promise to customer (RELII), Empathy (EMP) and Responsiveness (RES).

    In addition to the contributions, this study still has some limitations so that suggestions for future research are as follows:

    First, this study only surveyed customers of 09 commercial banks, so it still limits the generalizability of the research issues. Thus, further studies need to expand the scope in other banks in Thua Thien Hue province to explore; and analyze the relationship between service quality and customer satisfaction in banking sector.

    Second, this study only discovered the relationship between the components of service quality with customer satisfaction but it has not evaluated specific components of service quality and customer satisfaction. Therefore, further research is necessary to evaluate in more detail on this issue.

    Third, this study has not mentioned the component prices (interest rate, service charges) to the customer satisfaction. Meanwhile, the service price can be very influential on satisfaction perception and value (Zeithaml and Bitner, 2000). According to Levesque and McDougall (1996) competitive interest rate is one of the important determinants of customer satisfaction in banking sector. Besides, this study has not tested the relationship between satisfaction to customer loyalty while between satisfaction and customer loyalty have positive relationships with each other (Donio et

    al., 2006; Story and Hess, 2006; Cheng et al., 2008). Therefore, further research needs to add component prices to factors affecting customer satisfaction as well as it must to test the relationship between satisfaction and customer loyalty to conduct research.
