Abstract
Purpose
This paper aims to extend Rossiter’s C-OAR-SE method of measure design (IJRM, 2002, p. 19, p. 4, pp. 305-335; EJM, 2011, p. 45, p. 11, p. 12, pp. 1561-1588) by proposing five distinct construct models for designing optimally content-valid multiple-item and single-item measures.
Design/methodology/approach
The paper begins by dismissing convergent validation, the core procedure in Nunnally’s (1978) and Churchill’s (1979) psychometric method of measure design which allows alternative measures of the same construct. The method of dismissal is the mathematical demonstration that an alternative measure, no matter how highly its scores converge with those from the original measure, will inevitably produce different findings. The only solution to this knowledge-threatening problem is to agree on an optimal measure of each of our major constructs and to use only that measure in all future research, as is standard practice in the physical sciences. The paper concludes by proposing an extension of Rossiter’s C-OAR-SE method to design optimal standard measures of judgment constructs, the most prevalent type of construct in marketing.
Findings
The findings are, first, the mathematical dismissal of the accepted practice of convergent validation of alternative measures of the same construct, which paves the way for, second, the proposal of five new C-OAR-SE-based construct models for designing optimal standard measures of judgment constructs, three of which require a multiple-item measure and two of which a single-item measure.
Practical implications
The common practice of accepting alternative measures of the same construct causes major problems for the social sciences: when different measures are used, it becomes impossible, except by remote chance, to replicate findings; meta-analyses become meaningless because the findings are averaged over different measures; and empirical generalizations cannot be trusted when measures are changed. These problems mean that we cannot continue to accept alternative measures of the constructs and that, for each construct, an optimal standard measure must be found.
Originality/value
The ideas in this paper, which have untold value for the future of marketing as a legitimate science, are unique to Rossiter’s C-OAR-SE method of measure design.

Abstract
Purpose
New measures in marketing are invariably created by using a psychometric approach based on Churchill's “scale development” procedure. This paper aims to compare and contrast Churchill's procedure with Rossiter's content‐validity approach to measurement, called C‐OAR‐SE.
Design/methodology approach
The comparison of the two procedures is by rational argument and forms the theoretical first half of the paper. In the applied second half of the paper, three recent articles from the Journal of Marketing (JM) that introduce new constructs and measures are criticized and corrected from the C‐OAR‐SE perspective.
Findings
The C‐OAR‐SE method differs from Churchill's method by arguing for: total emphasis on achieving high content validity of the item(s) and answer scale – without which nothing else matters; use of single‐item measures for “basic” constructs and for the first‐order components of “abstract” constructs; abandonment of the “reflective” measurement model, along with its associated statistical techniques of factor analysis and coefficient alpha, arguing that all abstract constructs must be measured as “formative”; and abandonment of external validation methods, notably multitrait‐multimethod analysis (MTMM) and structural equation modeling (SEM), to be replaced by internal content‐validation of the measure itself. The C‐OAR‐SE method can be applied – as demonstrated in the last part of the article – by any verbally intelligent researcher. However, less confident researchers may need to seek the assistance of one or two colleagues who fully understand the new method.
Practical implications
If a measure is not highly content‐valid to begin with – and none of the new measures in the JM articles criticized is highly content‐valid – then no subsequent psychometric properties can save it. Highly content‐valid measures are absolutely necessary for proper tests of theories and hypotheses, and for obtaining trustworthy findings in marketing.
Originality/value
C‐OAR‐SE is completely original and Rossiter's updated version should be followed. C‐OAR‐SE is leading the necessary marketing measurement revolution.

Abstract
This study examines how various characteristics of the discount retail environment and the overall attitude towards a discount retail store, considered to be an abstract and global image component, influence consumers’ satisfaction and how consumers’ satisfaction, in turn, affects store loyalty. The data, collected from a sample of 517 discount retail customers in Daegu, Korea, indicate that: (1) forming the overall attitude is more closely related to in‐store services: atmosphere, employee service, after sales service and merchandising, (2) store satisfaction is formed through perceived store atmosphere and value, (3) the overall attitude has strong influence on satisfaction and loyalty and its impact is much stronger on loyalty than on satisfaction, (4) store loyalty is directly affected by most significantly location, merchandising and after sale service in order, (5) satisfaction is not related to customers’ committed store revisiting behavior. The applications in management and implications for future research are discussed.

Abstract
Much of human behaviour is viewed as a process, which begins with early childhood experience, and develops into later life emotions, values, beliefs, and behaviours. Described below, considerable interdisciplinary attention has been given to the role of childhood, and more specifically, to the relevance of different types of parental influence on children as they later become adults. Within marketing, selected scholarly consideration has been devoted to the roles of parents on their children's existing consumer behaviour. The unique contribution of this article is to examine the role of different types of parental influence on later adulthood shopping behaviours.

Abstract
Purpose
The purpose of this study is threefold: To compare many old and new media channels in terms of a range of attributes such as perceived intrusiveness, reliability, trustworthiness, convenience, and entertainment value. To compare the perceived relative effectiveness of alternative communication channels in terms of how a marketing proposition is evaluated by recipients and thus to establish whether some channels are better than others for achieving engagement and persuasion. To additionally survey the senders of marketing communications, to examine potential differences between how senders think recipients perceive each channel and what recipients actually perceive. Moreover, it is proposed that the survey be conducted in both consumer and business markets.
Design/methodology/approach
First, in a survey, the channels are compared from the perspective of both receivers and senders of marketing communications and additionally from that of consumer and business markets. Second, by means of experimentally generated scenarios, the paper assesses the relative effectiveness of the 11 channels in eliciting responses to two typical B‐to‐C and two B‐to‐B promotion offers.
Findings
The paper finds that, although e‐mail is well established and widely used, the traditional channels of television, radio, newspapers and direct mail retain their historically favored attributes of trust and reliability of information that make them still preferred by consumer recipients of marketing communications, even by “tech savvy” younger consumers who use e‐mail and SMS extensively. Business receivers are more accepting of e‐mail marketing communications than are consumers but, like consumers, they are more likely to act on a marketing offer if it comes through traditional mass media or mail channels.
Originality/value
The paper enables marketing managers to assess the relative benefits of a number of marketing communication channels.

Abstract
This paper examines the believability of strong warnings about the negative consequences of drug use among young adults in Australia who have never tried, currently use, or have tried and rejected cannabis. It finds that the strong warnings about cannabis are generally believed by never‐triers. The same warnings are perceived by current users as only slightly believable. Surprisingly, but also consistent with cognitive dissonance, trier‐rejecters of cannabis are the most likely, more so even than never‐triers, to believe the warnings about cannabis. The paper also examines warnings about cocaine and heroin by cannabis usage status. Current users of cannabis, compared with non‐users, perceive the warnings about the harmful effects of cocaine as less believable, suggesting possible “gateway” susceptibility to trial of this drug. But for heroin, all groups perceive the warnings very believable. The beliefs about particular negative consequences that are most likely to lead to discontinuation of use of cannabis, and those that should discourage uptake of cocaine and heroin, are identified.
