Authors have long known of the need for ?cues? to assess the competence and training of providers of credence services. In the case of health care providers such as eye care professionals, one such cue is whether the eye care professional is ?board certified.? This study of 500 consumers who had had an eye exam either from an optometrist or an ophthalmologist examines four questions: what factors are important to a consumer seeking an eye-care provider, what is communicated by an eye-care provider?s claim of being board certified, whether there are differences in perception between board certification as applied to an optometrist and an ophthalmologist, and whether there are differences in the perceptions of optometrists who are board certified compared to those who are not board certified. The results show that board certification is an important cue for consumers in assessing the competence and expertise of optometrists and that board certification can be used to distinguish between an optometrist and an ophthalmologist. The results also show that optometrists who are board certified as seen as better trained and more competent than optometrists who are not board certified.

\section[{Introduction}]{Introduction}\par
n 1973 Darby and Karni identified a distinction between experience, search, and credence goods and services. According to \hyperref[b4]{Darby and Karni (1973)}, credence goods are goods and services "sold within relationships characterized by high levels of information asymmetry between buyers and sellers, with buyers Author: Department of Marketing Towson University Towson, Maryland USA. e-mail: tmaronick@towson.edu having to trust the sellers as to claims made, i.e., in situations where the seller determines the customers' requirements." Moreover, in the case of some services, such as health care, not only do consumers have almost no ability to assess what service is needed or the quality of the service to be performed, they may have difficulty evaluating the quality of the service even after it is received. In addition, in most cases involving health care, consumers don't have the ability to determine how the quality of the service received compares to other health care providers of the same service. This is because, as noted by  {\ref Parasuraman, Zeithami and Berry (1985)}, service experiences are systematically different because services are heterogeneous and, as a result, less predictable.\par
The question then becomes what kind of information is important to consumers as they seek to reduce the risks inherent in the purchase of these credence services? In other words, what sources of information can a consumer use as "cues" as to the competence and expertise of a health-care provider? One such "cue" is whether the health-care provider is "board certified" and, then the questions are whether the certification is important to consumers in their selection of a health-care professional and whether board certification is effective as a cue to the providers' expertise and competence.\par
This study focuses on one type of health-related service, eye care, and consumers' purchase of eye-care services from optometrists, who are state-licensed eyecare professionals but different from ophthalmologists, who are medical doctors specializing in eye care. Eye care was selected because eye care is a service with both a credence and an experience attribute, i.e., the consumers know if they see better after an eye exam but must rely on the expertise of the eye care provider to determine the need for treatment, i.e., a new or changed prescription, and because the consumer has no way of knowing whether the quality of the service received would be different if a different eye care provider had been selected. Specifically, the research questions are: 1. What factors are important in the selection of an eye-care provider? 2. How important was board certified in a consumer's decision to see their particular eye care provider?\par
3. What message is being communicated by an eye care provider who is board certified? 4. Is there a difference in perception of optometrists who are board certified eye-care providers and ophthalmologists, all of whom are board certified medical doctors specializing in eye care? 5. Are there differences in perception of an optometrist who is board certified and an optometrist who is not board certified?\par
The data for this analysis is a nationwide on-line survey of 500 consumers age 21 or older who had seen an eye-care professional (optometrist or ophthalmologist) in the prior three years. Board certification of optometrists or ophthalmologists was selected as a subject matter since ophthalmologists, who are medical doctors specializing in eye care, have board certification as a requirement to practice while board certification of optometrists is a relatively new phenomenon and is voluntary.\par
Thus, consumers' perceptions of the certification of ophthalmologists serve as a control to account for pre-existing beliefs regarding board certification in general and as it relates to board certification of optometrists. 
\section[{II.}]{II.} 
\section[{Prior Research}]{Prior Research}\par
The seminal article on credence goods and services is \hyperref[b4]{Darby and Karni (1973)} who introduced the concept of a credence good to \hyperref[b12]{Nelson's (1970)} earlier classification of search and experience goods. Other authors have expanded on the Darby and Karni continuum of credence goods to include services based, for example, on the level of risk associated with services (Zeithamal \& Bitner 2000; and Mitchell 1994); the level of information search with credence services \hyperref[b11]{(Mortimer and Pressey, 2013)}; and whether the services were provided in a professional-consumer or professional-business relationship \hyperref[b13]{(Ostrom \& Iacobucci 1995)}.\par
Additionally, authors have noted that professional services have characteristics similar to credence goods in that they are often customized for the individual \hyperref[b8]{(Lapierre, 1997)}, and frequently require interaction between the service provider and the consumer to create value (Hirvonen \& Helander 2001).\par
Importantly, as noted by \hyperref[b10]{Mitra and Capella (1999)}, there is reason to believe that consumers engage in different decision-making processes while evaluating credence services because the intangibility of services makes it difficult to assess the quality of the service. Thus, services in general and medical-related services in particular are perceived as associated with greater uncertainty and higher risks and, as a result, must be taken on faith. For example, as noted by \hyperref[b15]{Sun, et al (2012)}, a higher level of uncertainty leads consumers of credence services such as health-care to rely on non-alignable attributes, i.e., those that are unique to the particular provider of the service, as opposed to alignable attributes, which are discernable across service providers. Similarly, \hyperref[b7]{Hsieh and Hiang (2004)} found that, among consumers who had had a hospital visit, that "interaction quality," defined as the trust between consumers and the health-care providers, and "functional quality," defined as the attitudes, behaviors, and expertise of the health-care provider, were important criteria in assessing the value of credence services.\par
Other authors have examined the role of thirdparty certification for credence services, including certification of health care professionals. For example, \hyperref[b3]{Baldwin et al (2011)} found that credentialing, including certification programs, are developed by third-party health-related organizations to "?protect the public by establishing and ensuring a minimum acceptable standard of quality and performance for professionals working in population health ?"Also, \hyperref[b2]{Babakus et al (1991)} found that "?physicians have found that consumers value certification as an indicator of achievement, competence, and quality."\par
Similarly, Adams et al  {\ref (2002)} suggests that, in the case of midwife and nurse midwifes, being "certified" is an indication of competence that will forestall consumers' "drift to lowprice, low-quality alternatives" when selecting a healthcare (midwife) provider. On the other hand, \hyperref[b5]{Grosch (2006)} found "no credible link between specialty board certification and outcomes or quality of clinical care among medical doctors." Applying these findings to eye-care professionals, while consumers may, in varying degree, have the skill, knowledge, experience, and technical expertise to form expectations and performance assessments about some services they receive, no such skill or knowledge is likely to exist in the case of eye care. Thus, while consumers may engage in more involvement and more information search with credence services, there is limited opportunity for such search in the case of eye-care providers. This is called "asymmetry of information" \hyperref[b16]{(Zeithaml and Bitner 2000)} because sources don't exist to enable a consumer to determine if optometrist A is more competent, or better trained than optometrist B. Hence, the role of a cue such as board certification as a measure of credence factors such as expertise, training, and quality of care is likely to be an important factor in a consumers' decision as to who to choose as his/her eye-care professional. 
\section[{III.}]{III.} 
\section[{Methodology}]{Methodology}\par
The data were collected from a nationwide sample of 500 consumers drawn from an internet panel of individuals who have agreed to participate in internet surveys on a periodic basis. The universe for this study is adults age 21 or older who have seen an eye care provider (optometrist or ophthalmologist) within the prior three years. Respondents who agreed to participate in the on-line survey were first asked a series of qualifying questions related to whether they wore contact lenses or glasses prescribed by an eye care provider and whether they had received their eye care from either an optometrist or an ophthalmologist. Respondents were then asked what factors were important in their selection of an eye-care provider, whether they believe the eye care provider they had seen, i.e., an optometrist or ophthalmologist, was "board certified," and the importance of their eye care provider being board certified. They were also asked what it meant to be "board certified" (in general) and what a claim of being board certified says about that eye care provider and whether there are any differences in training, competence, or expertise between an optometrist who is board certified and one who is not board certified.\par
IV. 
\section[{Findings a) Demographic Profile}]{Findings a) Demographic Profile}\par
As noted in Table \hyperref[tab_0]{1}, 71\% of respondents were female, almost half (47\%) had either a 4-Year college or graduate degree, and 58\% had seen an optometrist in the past three years while a third (42\%) had seen an ophthalmologist.  \hyperref[tab_1]{2}, the provider's professional qualifications was seen as the most important, rated as "very important" or "extremely important" by 75.8\% of respondents, followed by his/her reputation (71.9\%), his/her personal qualities (69.9\%), and board certification (68.1\%). What is particularly noteworthy is that 68.1\% of respondents viewed board certification as "very important" or "extremely important," even though there was no mention of board certification in any prior question. The second research question examines the specific importance of board certification in a consumer's decision to see a particular eye-care provider. Respondents were first asked whether the eye care provider they saw was board certified. As noted in Table \hyperref[tab_2]{3}, significantly more respondents (?=.05) who had seen an ophthalmologist said they believed he/she was board certified, compared to 73\% of those respondents who had seen an optometrist. This latter result is noteworthy since it is estimated that less than five percent of optometrists are board certified by either of the optometric associations (American Optometric Society, Inc. vs American Board of Optometry, Inc. 2011). Computation of traditional estimates of statistical precision technically require a probability (random) sample. However, statistical estimates using non-probability samples can be used to provide some estimate of likely sampling error. Under appropriate statistical assumptions, a total sample size of 504 will produce confidence intervals for statistical estimates that are no greater than +/-5.9\% 95\% of the time.\par
All respondents were next asked how important, if at all, it is that their eye care provider be board certified. As noted in Table \hyperref[tab_3]{4}, 62.5\% of respondents who had seen an optometrist said it was "very important" or "extremely important" that their eye care provider be board certified while 70.8\% of respondents who had seen an ophthalmologist indicated it was "very important" or "extremely important" that they be board certified. Respondents were then asked their reason for a belief that it was important or unimportant that their eye care provider be board certified, with their verbatim responses recorded. Among the reasons as to why being board certified was important across all respondents were such statements as "I only have one pair of eyes, I want them taken care of by a professional," "it certifies that he has the qualifications I needed," "I feel more assured of his/her competence if he/she is board certified,""it gives comfort that he has the required skills to perform job," and "it means he or she has passed a series of qualification tests from peers representing the industry." Among, those who said board certification was unimportant, the primary reason was that being "licensed" is seen as the same as being "board certified."

The third research question asks what message is being communicated by an eye-care provider who is board certified. In order to address this question, respondents where shown a series of statements regarding board certification of eye care providers and asked whether they believed each statement was "Definitely/Probably Correct" or not. As noted in Table \hyperref[tab_4]{5}, consistent with prior research regarding the perception of providers of credence services like health care providers, two-thirds of the respondents (64\% -68\%) believe that eye-care providers who are board certified: a) are more competent than eye care providers who are not board certified, b) have completed residency training, and c) have more formal training than an eye care provider who is not board certified. Importantly, however, less than half of all eye care consumers (45.7\%) believe that being board certified is necessary to provide eye care.

The fourth research question sought to determine if consumers' perceptions of eye-care providers who had seen an optometrist are different from perceptions of consumers who had seen an ophthalmologist. In order to answer this question respondents were asked whether there was a difference in the nature of the certification requirements for an optometrist to become board certified and the requirements for a medical doctor to become board certified in ophthalmology. As noted in Table \hyperref[tab_5]{6}, in all credence-factor categories raised, significantly more respondents see ophthalmologists as having higher requirements for board certification than optometrists, including 80\% of respondents believing that a medical doctor must "pass a qualifying exam/test" to become board certified in ophthalmology, compared to 66\% who believe an optometrist must pass a qualify exam to be board certified. All respondents, regardless of who their eye care provider was, were asked about the fifth research question, i.e., their perceptions of optometrists who are board certified and those who are not board certified. Specifically, they were shown a series of statements and asked whether the statement was "definitely or probably true" or "definitely or probably not true." As noted in Table \hyperref[tab_6]{7}, some of the noteworthy results are that significantly more respondents believe an optometrist who is board certified: a) is more competent than one who is not, b) has more training than one who is not, and c) is more of a specialist than one who is not. Also, over a third of respondents don't believe that an optometrist who is board certified just paid a fee to be certified. On the other hand, being board certified is not seen as necessary to treat particular types of diseases or to write prescriptions. Moreover, when the data in Table \hyperref[tab_6]{7} were analyzed by sub-group (i.e., optometrist v. ophthalmologist) the results show similar perceptions of board certification for optometrists and ophthalmologists, suggesting that at least some of the basis for perceptions of board certification for optometrists comes from respondents' pre-existing beliefs regarding board certification of ophthalmologists. V. 
\section[{Conclusions}]{Conclusions}\par
Four conclusions flow from this study of consumers who have seen either an optometrist or an ophthalmologist for eye care. First, credence factors such as personal qualifications and reputation are the most important factors consumers use when selecting an eye-care provider, with "board certification" being the fourth most important factor in their decision. Second, the importance of board certification is not significantly different when the consumers' eye-care provider was an optometrist and when he/she was an ophthalmologist. Third, board certification provides a cue as to competence and training of a credence service provider such as eye-care providers and, theoretically, can be used to distinguish between the competence and training of optometrists based on whether they are board certified or not Also, board certification can be used, at least theoretically, to distinguish between optometrists and ophthalmologists, particularly since ophthalmologists are seen as more competent and more of an eye care specialist, based on the perception that the requirements for board certification for an ophthalmologist are higher than for an optometrist. Fourth, and most importantly, while board certification serves as a cue as to competence, it is not an effective cue that consumers can use in deciding what type of eye care provider to use, given that 73\% of respondents who saw an optometrist (as opposed to an ophthalmologist) believe their eye care provider was board certified when estimates are that less than 5\% of optometrists are board certified. Apparently, simply because the optometrist was licensed by the State as an eye care provider leads consumers to believe he/she is board certified.

\section[{Policy Implications}]{Policy Implications}\par
First, public entities at the Federal and State level, working with professionals and academics in the field of optometry, need to establish uniform standards for board certification in order to provide an environment of trust such that the consuming public can be assured The Role of Board Certification as a Cue to Competence of Eye Care Providers: An Empirical Analysis organizations must establish and maintain rigorous standards for certification that include additional training and coursework, and periodic assessment of optometrists' performance to assure that, consistent with consumer perceptions, "board certification" of an optometrist can be used by a consumer as a "cue" to an eye-care provider with the highest level of expertise, competence, and training. Finally, the results of this study clearly show the need for optometrists to distinguish themselves from ophthalmologists and articulate the benefits of board certification.
