Supermarket self-checkout service quality,customer satisfaction,and loyalty: Empirical evidence from an emerging market

Supermarket shoppers around the world are increasingly encountering and using self-service technologies (SSTs) during their shopping process. The SSTs are mainly offered to reduce retailer costs and enhance customer's experience. Among the many different SSTs available, self-checkout systems (SCS) have become an extremely popular choice of supermarkets around the world. Although some of the main motivations of the supermarkets for offering SCSs are cost cutting, speed, and convenience, supermarkets are also assuming that these services would enhance customer experience, satisfaction, and ultimately loyalty. However, empirical evidence is needed to better understand customer expectations of SCS service quality and how technology based service quality impacts retail patronage. Therefore, the purpose of this research is to examine the service quality of supermarket/grocery store SCSs and its impact on customer satisfaction and loyalty in an emerging market, namely Turkey. Using the SSTQUAL scale (Lin and Hsieh, 2011), data (n=275) for the study is collected from shoppers who had just completed going through the self-checkout counter in a large supermarket chain. The results of this study show that SCS service quality positively influences loyalty through the customer satisfaction path. Managerial and research implications of the findings are discussed.     

The effect of self-checkout quality on customer satisfaction and repatronage in a retail context

Self-service technologies (SSTs) are defined as technological interfaces that enable customers to produce a service without direct employee involvement. Among various SSTs, self-checkouts are being tested by grocery stores across the world. However, while most studies focus on SST adoption, there is limited research on its impact on service quality, customer satisfaction, and retention. Our study investigates consumers’ assessments of self-checkout in a retail outlet, and its influence on post-usage intentions. The study presents a causal model in order to determine (i) whether consumers evaluate service quality for self-checkout based on five different attributes: speed, ease-of-use, control, reliability, and enjoyment; (ii) whether the evaluation of service quality differs according to demographics and usage frequency; and finally (iii) if service quality delivered by self-checkout relates to overall customer satisfaction and retail patronage. We conclude that successful use of self-checkout may "tie" consumers to a provider, representing a feature that differentiates a retailer from competitors.     

Self-service innovativeness scale: introduction,development, and validation of scale

Consumer innovativeness is a central variable in innovation diffusion and adoption literature. The foremost challenge confronted by investigators involved in innovation diffusion and adoption research is the problem of measuring the innovativeness construct. Furthermore, a scale measuring innovativeness towards self-service technologies (SSTs) adoption is required as SSTs have grown considerably in the last few decades. To this end, this study develops and validates a self-service innovativeness (SSI) scale applicable across a variety of SSTs. The study presents a series of six distinct phases describing the development and validation of a six-item, self-report scale. The innovativeness scale has been validated in different contexts, allowing comparisons across distinct samples (i.e., student vs. non-student sample) and different industries (i.e., retail and hospitality industries). The SSI scale presented in this paper is short, valid, reliable, and easy to administer in service domains.     

Re-assessment of E-S-Qual and E-RecS-Qual in a pure service setting

Understanding and measuring electronic service quality including its dimensions has become crucial since a growing volume of business takes place in the cyber world. This paper focuses on measuring electronic service quality and service recovery issues by means of E-S-QUAL and E-RecS-QUAL scales in a pure service oriented setting and across a culturally different consumer group than the original scale. This research covers 2017 customers' assessment of the electronic service quality offered by 13 banks in Turkey. Findings suggest a refined and more stable version of the E-S-QUAL scale for the internet banks. Comprehensive psychometric tests also suggest that E-RecS-QUAL is an appropriate tool to evaluate online service recovery in consumer research.     

Exploring factors which motivate older consumers’ self-service technologies (SSTs) adoption

Although the proportion of the older population is growing, the majority of research on technology adoption behaviour, such as the adoption of self-service technologies (SSTs), tends to focus on younger consumers. To fill this gap, this study is designed to explore factors which motivate older consumers’ adoption of SSTs by applying Gatignon and Robertson’s diffusion process model. Responses were collected from 104 respondents who were aged 55 or over and who had used self-checkouts in the past. The data were analysed using partial least squares path modelling with SmartPLS 3.0 software. The results indicate that perceptions of SST characteristics, including usefulness, enjoyment, and control, are indirect antecedents of older consumers’ SST adoption through service quality and/or perceived risk. Another key predictor of older consumers’ adoption of SST is prior usage experience with SSTs, which strongly influences usefulness and compatibility. Findings from this study contribute to the literature because little research has explored what drives older consumers to use SSTs.     

Assessing Perceived Quality in Industrial Service Settings:

The development and application of a 22-item perceived service quality measure for the flight attendant segment of airline catering services is described. This ''performance-only'' scale emerges as a unidimensional measure with better psychometric properties than an alternative formulation based on ''performance x importance'' scores. Results of hypotheses tests provide evidence supporting the proposition that service performance exerts a significant influence on behavioral intentions via the mediating role of overall service quality perceptions. In addition, the study provides insights of a practical nature within an ongoing quality improvement environment. In particular, the measure provides actionable information for decision makers. Implications of the findings for researchers and industrial services marketers are discussed.     

An independent assessment of the unidimensionality,reliability, validity and factor structure of the LibQUAL+™ scale

This empirical study provides a thorough measurement analysis of the LibQUAL+? scale for measuring library service quality. In particular, the study assesses the unidimensionality of the scale, the scale's psychometric properties and its factor structure. Data were gathered using a self-administered questionnaire distributed to a sample of university library users: 189 in Canada and 374 in Mexico. Using confirmatory factor analysis (CFA), the study confirms the assumption of unidimensionality in only two of the three current sub-dimensions of the scale. The results of this study also show that the LibQUAL+? scale consists of four dimensions. The remainder of the CFA results in the study provides strong support for the general reliability and validity of the four-dimensional structure.     

Asymmetric Effects of Regulatory Focus on Expected Desirability and Feasibility of Embracing Self‐Service Technologies

This research draws on regulatory focus theory to examine the asymmetric effects of regulatory focus (promotion focus versus prevention focus) on expected desirability and feasibility of using self‐service technologies (SSTs) in a retail setting. To study consumers’ SST trial intention from the perspective of regulatory focus theory, this research first integrates the attributes of SSTs explored in prior studies into a desirability–feasibility framework. The proposed asymmetric effects of regulatory focus (promotion focus versus prevention focus) lie in both scope (on desirability, feasibility, versus both desirability and feasibility) and valence (positive versus negative): The promotion focus facilitates consumers to recognize both desirability (consumption value) and feasibility of using SSTs, whereas the prevention focus inhibits consumers from understanding the feasibility‐related attributes of SSTs. In addition, it is proposed that the promotion focus contributes to the easement of consumers’ technology anxiety, whereas the prevention focus has a reverse effect. Furthermore, expected desirability (consumption value) and feasibility both positively influence consumers’ intention to adopt SSTs, whereas technology anxiety negatively affects consumers’ trial intention. Structural equation modeling is used to test the overall model, and the results support the hypotheses in general.     

Technology readiness and the evaluation and adoption of self-service technologies

As companies struggle to persuade their customers to adopt new self-service technologies (SSTs), it has become increasingly important to understand the factors affecting customers’ attitudes towards these SSTs and their adoption behaviour. Technology readiness (TR), i.e. the customer's mental readiness to accept new technologies, has been proposed as such a factor. TR comprises four dimensions: innovativeness, optimism, discomfort and insecurity. This article investigates the effects of TR on customers’ (1) attitudes towards using SST for airline check-in, (2) adoption of self-service check-in, and (3) evaluations of a new self-service check-in on the Internet, in terms of perceived service quality, satisfaction and loyalty. An empirical study was conducted among loyalty program customers of a European airline, having access to Internet check-in. Data were collected with online and traditional mail surveys, resulting in 1258 usable responses. Analysis of the data revealed that only optimism and innovativeness formed unique individual dimensions. Furthermore, TR had surprisingly little impact on customer attitudes towards SST, on adoption behaviour, and on SST evaluations. Optimism explained consumer behaviour towards SSTs best, whereas innovativeness had only a marginal effect on attitudes towards using the Internet or a mobile phone to check-in. The article concludes with a discussion of the validity of the TR construct and suggestions for future research. Managerial implications are provided.     

Fairness quality: a conceptual model and multiple-item scale for assessing firms’ fairness – an exploratory study

Abstract

Scholars suggest that fairness is a precursor to ethical firm behaviour. Existing research suggests that (1) commonly used single-item fairness measures lack reliability and validity, and (2) single-item scales do not contribute to understanding fairness as a multidimensional concept. Using the means-end framework, we develop a measure of fairness quality (FQ) of service experience. We conceptualise, construct, refine and test the FQ scale over multiple stages of data collection. Using the soft-laddering interviewing technique, we initially explore FQ attributes. Subsequently, we design and conduct two surveys to test the FQ measure. The final scale contains 18 items in four dimensions: transparency, associations, moderations and process. The FQ scale demonstrates good psychometric properties, passing all reliability and validity tests. The scale extends existing research on fairness and provides a new conceptualisation of FQ. Marketers are encouraged to manage their FQ systematically to stimulate social and ethical behaviour. We present theoretical and managerial implications, with future research directions.     

The perceived credibility of quality labels: a scale validation with refinement

In this paper, we present quality labels as signals that reduce problems that arise under asymmetric information. We propose to closely scrutinize the concept of signal credibility, which is a key determinant of signalling effectiveness. In order to assess the perceived credibility of a quality label, we offer a revisited version of a scale originally proposed by Larceneux. The data used in this paper involve three different labels and were collected using self‐report surveys administered to 602 respondents. Based on findings from a variety of reliability and validity tests, the scale demonstrates good psychometric properties. Both theoretical and managerial implications are discussed, along with limitations and future research directions.     

An alternative measure for assessing perceived quality of software house services

Since the notion of perceived service quality and the disconfirmation paradigm were introduced in the IS community, quite a few studies have employed the SERVQUAL scale to measure perceived service quality. However, the instrument's psychometric properties have been seriously questioned, not only within the IS domain but also in many other contexts in which it has been tested. Yet, so far, no attempt has been made to develop and validate an alternative instrument specifically tailored to tackle the provision of b2b services such as those pertaining to MIS design and maintenance, despite the fact that quite a few researchers have made clear the need for doing so. Responding to this gap, the present study reports the results of an effort to validate INDSERV, an alternative to SERVQUAL. According to the findings, when slightly attuned by collapsing two specific dimensions into a single one, INDSERV outperforms SERVQUAL in all tests performed regarding dimensionality, reliability, convergent and discriminant validity as well as in concurrent validity.     

Robotic service quality – Scale development and validation

Viewing robots as service agents that provide services to customers for value exchange, the study developed a scale to measure robotic service quality. The scale underwent several stages of development including item generation, domain specification, scale refinement, and validity testing, including internal and external cross validation. A range of methods were used in this process. Data were collected from Australia, China, and Vietnam to test external validity. Four dimensions were identified to represent robotic service quality. Development of this scale has implications for artificial intelligence and service research. The scale can be used by practitioners to enhance customer experience and generate positive attitudinal and behavioural responses from customers.

Frontline employees׳ attitudes towards self-service technologies: Threats or opportunity for job performance?

Increasing diffusion of self-service technologies (SSTs) on the points of sale impacts on traditional retailing from several perspectives. For instance, SSTs have direct effect on front-line employees. Indeed, they may cause a potential reduction in personal contacts with clients, reduction of workers, modifying the job conditions and so on. To date, the effect of SSTs on the points of sale has been mainly investigated from a consumers׳ perspective, by mainly focusing on consumers׳ acceptance and usage of these systems. The aim of this paper is to make employees׳ point of view clearly emerge, through a qualitative approach focusing on the investigation of employees׳ perception of the consequences of these technologies on job performance. The content analysis based on exploratory in-depth interviews involves 250 frontline employees. Authors examine the success of technology from employee׳s standpoint by evaluating their attitude and considering the impact on their job performance perception. In this way, the analysis allows defining new variables which are not previously investigated, such as the perception of speed for task completion, which emerged as the most important factor for employees׳ self-evaluation. Hence, this study offers support for evaluating job performance considering the specific case of SSTs in the frontline employees as initial insights rather than definitive understandings.     

The impact of basic human needs on the use of retailing self-service technologies: A study of self-determination theory

Self-service technologies (SSTs) are becoming increasingly popular in retailing contexts. Previous theories of SST adoption have largely ignored the basic human needs, such as competence, autonomy and relatedness, that drive customer motivation and the use of SSTs. We address this theoretical gap and examine self-determination theory (SDT) in the context of the supermarket self-checkout. Based on the argument proposed by SDT, self-determined motivation is hypothesized to mediate the relationships between autonomy, competence, and perceived anonymity, and the intention to use SSTs. Data collected from 361 respondents form a structural equation model and support these hypotheses. The current study is important as it helps understand the role of customers' participation in the self-service. Managerial and theoretical implications are suggested.     

How do we measure the intangible? Overcoming the measurement challenge in services

Measuring service tangibility and intangibility aspects has been an interest to service researchers. While the Likert rating scale has been widely employed for measuring mental intangibility or its dimensions, it is not free from issues such as different anchoring, that is, the same words pointing to different attitudes and understanding for different individuals. The present study proposes the usefulness of a discrete choice experiment (DCE), where respondents are asked the same questions (i.e., items) and are presented with a scale while dichotomizing the possible responses for each scale item. We show that our proposed method is accurate and generalizable across contexts and samples through multiple studies. The DCE method gives managers a better way to measure intangibility or similar service constructs like service quality, which can help them manage their service offerings and make customers happier.     

Scale modification: alternative approaches and their consequences

Important marketing scales such as SERVQUAL are often adapted for use in a particular applied/theory-testing context and/or refined using some statistical method, assuming the resultant scale will have improved psychometric properties for a particular application. However, little attention has been paid to the consequences of how scale modifications are made, the criteria that are used to assess how well a modified scale performs, and whether scale modification is in fact worthwhile. To investigate these issues, we review approaches to scale modification, select an influential marketing scale and use context, and then examine the effects of the different scale modification approaches on which items are included in the refined scale. We then cross-validate the psychometric performance of the resulting scales using criteria that reflect the multiple purposes to which a scale can be applied. The results show approaches that leads to a more reliable scale for one purpose (e.g., segmentation) can be far less adequate for another purpose (e.g., benchmarking).     

On the Potential for Advertising to Facilitate Trust in the Advertised Brand

The Viewer Response Profile (VRP) scale is often used in commercial advertising research, and frequently used and cited in the academic advertising literature. This paper describes an investigation of the psychometric soundness of the Schlinger scale among a very large sample of respondents (N = 4,800) who each view a single ad from a large set of ads. Confirmatory factor analysis (CFA) provides an alternative parsimonious 20-item version of the scale that is found to exhibit superior psychometric properties. Managerial and research implications are discussed and suggestions for further improvement of the scale are offered.     

Measuring the Perceived Quality of Professional Business Services

Professional firms serving business clients are recognizing the need for improved quality services. Unfortunately, measures of professional service quality have proven difficult to develop. This paper reports on the use of SERVQUAL, an instrument commonly used to assess consumer perceptions of service quality. This instrument was employed with a sample of business owners who were asked to rate the quality of service received from their accounting firm. Although several dimensions of the scale proved useful, additional quality related factors emerged from the analysis.
