The Jungle of Support: What Do We Really Mean When We Say “Residents’ Support”?

: The aim of this research is to provide a conceptual framework to facilitate the standardization of the concept of “residents’ support” in tourism studies. The model is designed to prevent ambiguity and confusion that may arise in the use of the generic term “residents’ support.” Social Exchange Theory and the Theory of Reasoned Action will be incorporated for the purposes of contextualizing the term “residents’ support” with respect to three dimensions: attitudinal, intentional, or behavioral. A longitudinal analysis of the term “residents’ support” will be conducted on the basis of the proposed model. Fifty-four articles published between 2004 and the ﬁrst quarter of 2020 have been studied to classify the items used to create the construct of “residents’ support” in tourism studies and to draw conclusions about the work of scholars and tourism agents.


Introduction
Five decades have passed since 1970, when interest was first shown in analyzing how residents of a destination perceive the impacts of tourism and how this perception is linked to the support they provide for further development. [1] Suess, Woosnam, and Eru, (2020) claim that these studies have been vital in explaining the sustainability of tourism in destinations and recommending policies related to visitor management and industry development.
Throughout the years in which research has been conducted, efforts have been made to create a more standardized theoretical framework of reference. The research in this area appears to be transitioning away from a poor level of methodological refinement and an inadequate theoretical framework towards a more advanced level, thereby striking a better balance between methodology and theory ( [5] Nunkoo, Smith, and Ramkissoon, 2013; [6] Sharpley, 2014).
As the volume and complexity of publications has increased, the confusion surrounding the terminology has also grown apace. This is becoming more acute at a time when the sector recognizes the need to look beyond residents' attitudes and study their behavior towards tourism. While the co-existence of terms such as support, perceptions, attitude, intention, and behavior in current research both enriches and expands the object of the study, it also adds to the confusion and ambiguity surrounding the terminology used. In this sense, [9] Prayag (2013) stresses the need to distinguish negative link between negative attitudes and pro-tourism behavior. [37] Wu, Tsai, and Lee (2017) indicate that attitude is the most powerful variable that can influence intentions regarding tourism. However, some studies have shown that attitudes are weakly associated with behavior [38] (Krosnick and Richard, 1995), that behavior is influenced by more variables than attitudes [39] (Azjen and Fishbein, 1980), and that the most intense attitudes are those that best predict actual behavior [40] (Howe and Krosnick, 2017).
When research focuses on residents' intentions regarding tourism development, various expressions are used to refer to the construct, such as intentional behavior [41] (Fishbein and Ajzen, 1975), intention to act (11) (Jackson and Inbakaran, 2006), or intention to support [42] (Kwon and Vogt, 2010), and are shaped by a variety of items that express a certain intention, e.g., "I am willing," "I would like," "I would be willing to," and "I intend to." When researching behavior, the issues created by the variety of terms and items surrounding the construct ( [43] Lepp, 2007; [44] Peter, Chung-Shing, and Legerer, 2018; [9] Prayag, Hosany, Nunkoo, and Alders, 2013; [34] San Martin, García, and Herrero, 2017) are compounded by those caused by the variety of behaviors that residents can display towards tourism development: participation in tourism activities in their communities [34]  The TRA developed by [41] Fishbein and Ajzen (1975), expanded by the Theory of Planned Behavior (TPB) developed by [51] Ajzen and Madden in 1986, can be regarded as an effective initial solution that incorporates attitude, intention, and behavior, and bridges the "attitude-behavior gap." It also prevents confusion of these three terms. Not surprisingly, this theory attempts to predict behavior on the basis of attitude. As shown in Figure 1, according to this model, behavior is directly determined by intention. This variable is, in turn, influenced by another two: attitude (the subject's positive or negative assessment of behaving in a certain way) and subjective norms (the subject's judgement of how likely it is that people important to him/her would expect him/her to behave as predicted). In turn, attitude is determined by subjective probability and subjective desirability. Subjective norms depend on normative belief and the motivation to conform to these beliefs. However, some studies have shown that attitudes are weakly associated with behavior [38] (Krosnick and Richard, 1995), that behavior is influenced by more variables than attitudes [39] (Azjen and Fishbein, 1980), and that the most intense attitudes are those that best predict actual behavior [40] (Howe and Krosnick, 2017).

A Conceptual Model for "Residents' Support"
In the light of the above, our goal is to propose a conceptual framework that integrates SET and TRA in order to facilitate a more standardized approach to the concept of "residents' support", establishing whether it has been considered from an attitudinal, intentional, and/or behavioral perspective. It should be noted that our proposed conceptual model ( Figure 2) only partially considers the TRA, exclusively incorporating the terms relating to attitude, intention, and behavior (attitude towards behavior, intentional behavior, and actual behavior), and thus excluding the concept of subjective norm. The reason for this is that these are the concepts to which the term of support could refer.

A Conceptual Model for "Residents' Support"
In the light of the above, our goal is to propose a conceptual framework that integrates SET and TRA in order to facilitate a more standardized approach to the concept of "residents' support", establishing whether it has been considered from an attitudinal, intentional, and/or behavioral perspective.
It should be noted that our proposed conceptual model ( Figure 2) only partially considers the TRA, exclusively incorporating the terms relating to attitude, intention, and behavior (attitude towards behavior, intentional behavior, and actual behavior), and thus excluding the concept of subjective norm. The reason for this is that these are the concepts to which the term of support could refer. Firstly, it should be emphasized that-from a psychological perspective-attitudes, intentions, and behaviors are different concepts with a specific definition, while the term "support" remains broad and generic.
The term "support" is defined by the Cambridge Dictionary as: "to agree with and give encouragement to someone or something because you want him, her, or it to succeed. Approval and encouragement given to someone or something; to help someone emotionally or in a practical way; to accept something and allow it to happen".
Attitude is defined as the degree to which a person has a favorable or unfavorable evaluation or appraisal of the behavior in question ( [52] Ajzen, 1991, p. 188); general assessments (positive or negative) that people make about what happens around them, including people, ideas, and objects ( [53] Eagly and Chaiken, 1993; [54] Petty and Cacioppo, 1986). Attitudes can hold affective (emotions), cognitive (beliefs), and behavioral information, but they are a single global mental construct relating to the summary of all information reported in an assessment. Attitude is usually measured with items that include the following expressions: I support…; I believe…; I am happy…; I am against…; I am proud…; I think that …; I oppose….; I perceive… Intention is "the amount of effort one is willing to exert to attain a goal" [52]   Firstly, it should be emphasized that-from a psychological perspective-attitudes, intentions, and behaviors are different concepts with a specific definition, while the term "support" remains broad and generic.

Finally, behavior is "an organism's external reactions to its environment. Human behavior is the term used to describe a person's actions and conduct. Is an attempt on the part of an individual to bring about some state of affairs" [60] (Ossorio, 2006, p. 49). It is common to use expressions such as: I practice . . . ; I help . . . ; I recommend . . . ; I visited . . . Figure 3 shows an example of how each of the previous concepts could be reflected, for the case of a specific typology of resident behavior (the information that residents give to the tourist about things to see or do in the locality).

Intentions capture both the level of the set goal or behavior and the person's level of commitment" [59] (Sheeran and Webb, 2016). Finally, behavior is "an organism's external reactions to its environment. Human behavior is the term used to describe a person's actions and conduct.

The proposed model outlines a threefold approach to "residents' support" as a dependent variable: attitudinal support (AS), intentional support (IS), and behavioral support (BS). This implies that the resident's support could mean different things depending on whether it is considered from an attitudinal, intentional, or behavioral perspective.
The model is designed to prevent ambiguity and confusion that may arise in the use of the generic term "residents' support" in resident studies. The aim of the conceptual model is not to standardize the concepts of residents' attitudes, residents' intentions, or residents´ behaviors. The proposed model is also not designed to recommend the generic term "residents' support" to be selected earlier than before.
As the term "residents' support" is not exclusively linked to attitude, intention, or behavior, the model aims to highlight the importance of establishing the meaning (attitudinal, intentional, or behavioral) of the term "residents' support" prevalent in each investigation, delimiting a priori what dimension/s of support is/are to be analyzed in each study, and thus to avoid the confusion created when it is used as a catch-all term. The proposed conceptual model offers two benefits: firstly, its use facilitates comparison between different research studies (inter-research level) by clearly identifying the meaning of the term "residents' support" that each of them refers to. Secondly, it is advantageous at the intraresearch level (in an individual research) because it prevents the creation of a confusing and ambiguous "residents' support" construct due to the inclusion of a mixture of items pertaining to very different dimensions of support.
Finally, it also illustrates the importance of reducing the "attitude-behavior gap" by considering attitudes, intentions, and behavior, which favors the development of studies that include two or more constructs to measure "residents' support" from two or more different dimensions.

Methodology
Having clarified the terms of the proposed conceptual model, we will conduct a longitudinal analysis of the term "residents' support" in residents' studies in the field of tourism, taking the approach established in Figure 2 as a basis.
We will examine studies published in three leading tourism journals (Annals of Tourism Research, Journal of Travel Research, and Tourism Management) between 2004 and the first quarter of 2020. There are several reasons for this selection. First of all, the mere fact that they are academic journals guarantees that they are a source of information that contributes to research in a field (  The proposed model outlines a threefold approach to "residents' support" as a dependent variable: attitudinal support (AS), intentional support (IS), and behavioral support (BS).

Methodology
Having clarified the terms of the proposed conceptual model, we will conduct a longitudinal analysis of the term "residents' support" in residents' studies in the field of tourism, taking the approach established in Figure 2 as a basis.
We will examine studies published in three leading tourism journals (Annals of Tourism Research, Journal of Travel Research, and Tourism Management) between 2004 and the first quarter of 2020. There are several reasons for this selection. First of all, the mere fact that they are academic journals guarantees that they are a source of information that contributes to research in a field ( Limiting the review to these journals allows for initial testing of the proposed model, although we are aware that further relevant studies published in other scientific journals have been excluded from the analysis ( [ A three-step process was used to select the studies. Firstly, the authors conducted an online search in the databases of the journals combining the concepts of support and residents/host/locals/community in the title, key words, and/or abstract. Secondly, only full-length and empirical articles were selected to ensure that relevant information could be identified in the methods section, particularly the name given to the dependent variable measuring the residents' support of tourism, as well as the items used in its composition. That is why some qualitative works were eliminated despite their focus (e.g., [70] Monterrubio, Andriotis, and Rodríguez-Muñoz, 2020; [71] Spencer and Nsiah, 2013). Thirdly, studies in which "residents' support" was measured using a variable that does not expressly include the term "support" in its wording were eventually excluded ( [72]   . This three-step selection process made it easier to focus on the purpose of the research, which, as mentioned above, is to identify what we really mean from a terminological standpoint when we say "residents' support." Finally, a total of fifty-three articles met the inclusion criteria. Each article was then reviewed in order to identify seven major categories: authors, publication year, region under study, theoretical approach, method of data analysis, the precise term given to the support construct, and, when expressly identified, the items that formed the "residents' support" construct. The first six categories have been summarized in Table A1. Following that, for each individual study we searched for the specific items constituting the "residents' support" construct and, depending on the proposed conceptual model, classified them according to the support dimension they were related to: attitudinal support (Table A2), intentional support (Table A3), and/or behavioral support (Table A4).

Results
Table A1 (see Appendix A) collates information pertaining to authors, publication year, region under study, theoretical approach, method of data analysis, and the precise term given to the support construct. A column has been added that identifies, for each article, the dimension or dimensions of the support that it outlines, based on the individualized analysis of each of the items used in the construct (as shown in Tables A2-A4) (see Appendix B). The first columns of the table provide some general and methodological information about the selected works. The columns "Name of the support construct" and "Items related to . . . " serve to clarify whether the construct "residents' support" is standardized across different studies; in other words, whether the construct used in the collection of articles was unequivocally linked to a single specific dimension of support, or, on the contrary, whether the dimension of support used in the studies varied.
The studies conducted vary greatly in terms of the geographical location of the resident populations examined, with a total of 20 different countries. The leading countries analyzed were the USA (26%), China (11%), England (6%), Korea, Mauritius, Malaysia, and Brazil (each accounting for 5%), Australia, Canada, Greece and Iran (each accounting for 4%). Other regions with a token presence include Spain, Pakistan, Poland, Taiwan, Qatar, the Caribbean, Jamaica, and South Africa. They are grouped into the following major world regions: America (40%), Asia (25%), Europe (14%), Middle East (10%), Africa (8%), and Oceania (3%). A longitudinal analysis reveals the clear prevalence of U.S. studies in the early years, accounting for 64% of those analyzed between 2004 and 2010. There has been a progressive diversification of the areas under study since then, to the extent that most of the work With respect to the authors, it is important to note the presence of ten articles in which Dogan Gursoy is the co-author (18.5%), six are signed by Kyle Maurice Woosnam-one of them exclusively-(11.1%), and there are another six in which Robin Nunkoo is the co-author (11.1%).
As would be expected given the tradition in resident studies, the theory on which most of the analyzed articles are based is SET (79.2%); in some cases exclusively (54,7%) and in others it is accompanied by other complementary theories, and those with similar weighting (3 out of 43 cases) include TRA, Place Identity Theory (PIT), and Weber's Theory of Formal and Substantive Rationality (WFSR). SET is accompanied by the Stakeholder Theory on two occasions. Additional theoretical approaches used alongside SET to support the works included the following: Authenticity Perception, Emotional Solidarity, Community Attachment, Subjective Well-Being, Bottom-up Spillover Theory, Social Carrying Capacity Theory, Fairness Heuristic Theory, Social Dilemma Theory, and Cognitive Appraisal Theory, Destination Life Cycle.
The studies that did not apply SET (11 out of 53, i.e., 20.7%) used a range of approaches such as the Theory of Community Attachment, Stakeholder Theory, Institutional Theory, Quality of Life, Self-Perception Theory, Theory of Formal and Substantive Rationality, Complexity Theory, Weber's Theory of Substantive and Formal Rationality, Attitude Theory, Resident Empowerment, and Tourism Use History.
In terms of the statistical methodology applied, it should be noted that 38 out of 53 (71.7%) studies use the structural equation model (SEM), mainly through covariance-based SEM (CB-SEM) (33 out of 38, 86.8%), and 5 out of the 38 (13.2%) studies conducted use partial least squares SEM (PLS-SEM). Modeling is usually accompanied by exploratory and/or confirmatory factor analysis and principal component analysis. The remaining 28.3%, which do not use SEM, used other statistical methods including Multiple Regression Analysis (17%) and, less frequently, techniques such as exploratory and/or confirmatory factor analysis, principal component analysis, ANCOVA, and ANOVA.
Having summarized the most general and methodological aspects of the studies reviewed, the authors then conducted a full review of the items used to shape the concept of support in 53 of the studies compiled. Each study was assigned to the most appropriate support dimension column(s) (attitudinal, intentional, or behavioral) (see Table 1) in accordance with the scheme of Figure 1. It is important to point out that some articles are listed in several support dimension columns; this is because the items used to shape the support construct are related to several of the dimensions defined and not to a unique dimension as would be desirable. With respect to the term used for the support construct, "support for tourism development" has been used most frequently with 17 constructs out of the 57 analyzed (29.8%) (some articles produce 2 support constructs), followed by "support for tourism" with 13 (22.8%), "support for mega-events" with 10 (17.5%), and the support for certain types of tourism, such as Airbnb, short-term vacation rentals, World Heritage Sites, Red tourism in China, peer-to-peer accommodation, alternative tourism, and mass tourism. Consequently, from the outset it has been possible to see how the concept of support is used to address residents' support in a wide variety of situations associated with tourism in their localities, including tourism development in general, support for certain events, types of tourism, and tourism policy.
Furthermore, the last three columns of Table A1 (see Appendix A) indicate the type of support given by the resident for these developments. These types of supports are divided into the three dimensions of the support concept: attitudinal, intentional, and behavioral. Figure 4 offers a summary of the findings. With respect to the term used for the support construct, "support for tourism development" has been used most frequently with 17 constructs out of the 57 analyzed (29.8%) (some articles produce 2 support constructs), followed by "support for tourism" with 13 (22.8%), "support for mega-events" with 10 (17.5%), and the support for certain types of tourism, such as Airbnb, short-term vacation rentals, World Heritage Sites, Red tourism in China, peer-to-peer accommodation, alternative tourism, and mass tourism.

Furthermore, the last three columns of Table A1 (see Appendix A) indicate the type of support given by the resident for these developments. These types of supports are divided into the three dimensions of the support concept: attitudinal, intentional, and behavioral. Figure 4 offers a summary of the findings. An initial observation reveals a constant feature in resident studies, namely the use of the variable of support as a synonym of the "attitude of the resident towards tourism" ("attitudinal support" in the proposed terminology). Specifically, 86.8% of the articles analyzed exclusively link the concept of support to the attitudinal dimension, while 7.5% measure it with items that exclusively refer to the intentional dimension, and none of them measure behavior. In spite of the comprehensive nature of the concept of support, this demonstrates that the majority of the articles are centered around the analysis of a single dimension of the concept (94.3%), essentially focusing on the attitudes (86.8%) as opposed to intentions (5.7%), and that the area of behavior in not addressed in any case.
The sparse use of the term "support" exclusively associated with intention does not present a clear trend over time. On the contrary, it is homogeneously spread throughout the period under study, which shows that at no point does the concept leave the field of attitude to move on to that of intentions, and much less that of behavior, which is not addressed in any case.
The construct of support seeks to cover two or more of its potential dimensions simultaneously in only three articles (5.7%). In addition, the following comments are made on each of them: Lee (2013) [74] defined the latent variable "support for sustainable tourism development" on the basis of an item related to the attitudinal aspect ("I support the development of community-based An initial observation reveals a constant feature in resident studies, namely the use of the variable of support as a synonym of the "attitude of the resident towards tourism" ("attitudinal support" in the proposed terminology).

The construct of support seeks to cover two or more of its potential dimensions simultaneously in only three articles (5.7%). In addition, the following comments are made on each of them: Lee (2013) [74] defined the latent variable "support for sustainable tourism development" on the basis of an item related to the attitudinal aspect ("I support the development of community-based sustainable tourism initiatives") and another four items that reflect clear behavioral components related to participation and cooperation ("I participate in sustainable tourism-related plans and development", "I participate in cultural exchanges between local residents and visitors", "I cooperate with tourism planning and development initiatives", and "I participate in the promotion of environmental education and conservation").
Two years later, Zhou et al. (2015) [75] addressed the construct of "support for tourism", combining intentional ("I am willing to support tourism development") and behavioral ("I want to continue to participate in tourism or will to participate in the future") aspects.
Finally, Ritchie et al. (2020) [76] recently addressed the construct of "future event support" using items that cover the three dimensions of support, i.e., the attitudinal dimension ("residents were asked to indicate their overall support for hosting the 2012 Olympic events and associated development"), the intentional dimension ("please indicate the probability that you would support the hosting of future events"), and the behavioral dimension ("Did you visit any of the following events/places in Weymouth and Portland during the Games?", "Did you volunteer as a Weymouth and Portland ambassador or a Games maker during London 2012?").
If we look at the years in which these studies were published, it can be concluded that the use of items that combine different dimensions of the concept of support is a phenomenon that is confined to the second half of the analyzed period and that may be partially due to two aspects: (a) the greatest number of research endeavors pertaining to resident support identified in this second half (accounting for 68.5% of the analyzed articles); and (b) the recent addition to the field of resident studies of theoretical frameworks that complement the traditional SET and attempt to go beyond the knowledge of resident attitudes to explore their intentions and behaviors with respect to tourism development (the introduction of TRA from the psychological field into the domains of tourism research is a clear example of this).
Tables A2-A4 (see Appendix B) classify the articles pursuant to the support dimensions set out in the conceptual model and list the set of items used to measure the support variable. The analysis of these tables produces results in terms of the terminology used to measure each of the three support dimensions, and they serve as a reference for researchers in the selection of items to configure the variable.
As shown in Table 1, the most commonly used word among the 51 constructs analyzed containing items related to attitudes is "support". This word appears in 35 out of the 51 constructs (68.7%). This is another indication of the confusion surrounding the terminology related to this object of study. This word is followed by statements made by residents about what, in their opinion, tourism can entail for their locality-be it opinions, beliefs, desires, etc. In fact, these expressions appear in 19 of these 51 constructs (37.3%). Other expressions that constitute items related to attitude make reference to statements about the role of the government in the tourism development in the locality, appearing in 14 out of the 51 constructs (27.5%). Finally, a large part of the items are constructed with expressions that contain the following verbs: "I believe . . . " (21.6%), "I am proud . . . " (11.9%), "I am happy . . . " Furthermore, the expressions that appear most frequently, in 50% of the constructs, in the 6 constructs containing items related to the intentional dimension of support are as follows: "I would support . . . " and "I will . . . ," with the latter appearing in the following verbal forms: "I would be willing," "I will join," and "I am willing." Finally, the following appear among the different items: "I need to . . . ," "I want to . . . ," and "I should...," with each one of these contributing to the formation of a construct (16.67%).
Ultimately, the following stands out among the items that contribute towards measuring the dimension of support related to behaviors: "I participate . . . .," "I cooperate . . . .," "I visited . . . ," "I want to continue . . . ," and "I was a volunteer." All of these appear in just one of the three constructs identified in this support dimension, as few studies address the analysis of this dimension.
In summary, in light of the many items used in the evaluation of the three conceptual dimensions of support, the following expressions are most commonly used.

Conclusions
Over the last fifteen years, there has been an increase in the number of studies on the concept of "residents' support" published in the three tourism journals with the greatest impact in the Journal Citation Index (JCR 2018) [62] due to the increasing importance of the role that residents play in implementing tourism development processes.
This growing number of studies on residents' support requires a homogeneous methodology in order to draw comparisons between them, something touched upon by Boley and Strzelecka (2016) [7], in view of the lack of standardization of the scales used to measure the attitudes of residents towards tourism development in their localities. The problem is compounded further when the attitudinal dimension of support ceases to be unique and reaches the field of intentions and behaviors, including a variety of items in the composition of the same latent variable.
Both aspects are clearly reflected in the results of this study, which reveal the indisputable prominence of the attitudinal facet in providing semantic content to the concept of support, perhaps conditioned by the clear hegemony that SET has had and continues to have within the theoretical framework of resident studies. In fact, for many years the final objective of the majority of studies on residents has been to identify and explain the attitudes of residents towards tourism in their locality, analyzing the variables that influence them.
However, in recent years new theoretical frameworks have emerged which have sought to complement SET and move beyond perceptions and attitudes of residents to focus on their intentions and behaviors. This phenomenon has coincided with a paradigm shift in that the resident is no longer analyzed as a passive subject that endures or benefits from tourism development in his/her locality and has become an active agent that can favor or hinder the future of tourism in a region with his/her actions.
Accompanying this paradigm shift, new theories have escaped the strict psychological domain where they emerged to branch into new and complex phenomena, including tourism. One of the fundamental theories that has facilitated progress in resident studies in recent years is the TRA. The advantage of this theory is that it considers the attitudinal, intentional, and behavioral dimensions to be distinct and interrelated latent variables, which provides an innovative framework for future support studies to focus on their study without the need to incorporate items from each of these dimensions in the composition of each unique construct, as done previously by some of the articles analyzed.
The use of standardized terminology in accordance with the conceptual model presented in Figure 2 (irrespective of the dimensions of the support concept to be analyzed) would very much favor the comparison of studies. It would also be advisable to conduct studies that simultaneously include all the conceptual dimensions defined in Figure 1, albeit in separate constructs. From a theoretical and qualitative perspective, this study seeks to initiate a process of debate and reflection on the characterization and conceptualization of the items that should be used to develop the construct of "residents' support" in its different attitudinal, intentional, and behavioral dimensions.
A series of expressions are recommended for the wording of the items of the construct. In the case of attitudinal support (AS), these construct items could use verbs such as "I believe," "I think," or "I would like." For intentional support (IS), these could be "I will," "I need," or "I am going to." And for behavioral support (BS) these could be "I participate," "I cooperate," and "I visited." As regards the implications of this study for scholars, there are two points to be made: (a) There is a need to advance in the analysis of residents' support for tourism development and attempt to standardize the terminology used in the research. To do this, it is necessary to consistently clarify the dimension or dimensions of the support to be addressed and to be very clear about the items to be used to create the constructs of each of these dimensions, and (b) There is a need to advance in the analysis of residents' intentions and, above all, behavior, and to delve deeper into the attitude-intention-behavior sequence.
On the other hand, the analysis of the concept of residents' support, broken down into its different dimensions, will help entrepreneurs and public authorities in the destination to determine more thoroughly the role that the different groups and segments of the local population can play in promoting sustainable tourism development processes. To this effect, some studies have shown that attitudes are weakly associated with behavior [38] (Krosnick and Richard, 1995) and behavior is influenced by more variables than just attitudes [39] (Azjen and Fishbein, 1980). This study does, however, have several limitations. The first of these arises from the extended literature review, centered on articles published in the three most prestigious journals in the tourism field over a time period of fifteen years (2004 to first quarter of 2020).
In spite of these limitations, this study can be regarded as a reasonable starting point, from a conceptual and terminological perspective, to delve into other relevant issues, such as the validity of the items used to shape the support construct, as carried out in [7] Boley and Strzelecka (2016).
As future lines of research, it would be advisable to standardize the assessment scales used to quantify the different items that constitute each of the constructs. This would enable us to compare the findings of studies, in addition to their conclusions.
Furthermore, the preparation of empirical studies to create and test items and measurement scales for each of the dimensions of the support concept, the analysis of the actual interrelations that can arise between the different dimensions, and the classification of residents according to the different support dimensions are all areas of research to be pursued as a result of this study.
The literature and analysis are now focused almost exclusively on resident support in tourism. There are however other fields (e.g., urban development) where resident support is also analyzed. It would be worth investigating whether or not these fields suffer from the same ambiguity regarding the usage of the term, or if there is more consistency there. It also would be of interest to find out if there is a relationship between the context of the study and the way the concept of residents' support is defined/applied.
In applying the Theory of Reasoned Action to build the theoretical framework, this article focuses very much on the sequence attitude-intention-behavior. Although there is a logic in applying this simplified version of the TRA theory, given the arguments that studies should be directed at closing the attitude-behavior gap, it does raise the question if a different theoretical base (focused less on the step towards behavior and, e.g., more on the way attitudes are formed) would have lead to a different subdivision of the dimensions of residents' support. Given the large number of revised papers focused on the attitudinal support dimension, added value can perhaps be achieved by introducing a further differentiation of the concept of attitude by including the concepts of "Evaluation of Behavioral Outcomes" and "Behavioral Beliefs" (specified in TRA).
