This new social and work landscape inspired supranational institutions, such as the European Union, to develop theories for new educational systems. These Key Competencies seek the comprehensive training of students, on not only the cognitive but the socioemotional plane, as occurs with arts education. With this literature review, we intend to demonstrate the relationship between the Key Competencies as catalysts for the development of character strengths in students through art education programmes. The results conclude that it is possible to define a relationship between the Key Competencies and character strengths and to outline the nature of these relationships, noting that certain patterns of combinations of strengths are repeated in the Key Competencies. Additionally, our work leads us to propose the need to increase the volume of research in this field and to design future studies that allow an empirical evaluation of the nature of these connections and whether they are efficient and enduring.

Introduction Positive psychology is a branch of psychology that studies optimal human functioning from a scientific basis [ 1 ]. This trend, driven by Seligman, promotes research and the fostering of the positive aspects of the human being as the basis for happiness. Seligman bases his study on three pillars: positive emotions; positive traits, which are personal virtues and strengths; positive institutions, which should facilitate the development of the other two pillars. Furthermore, he proposes two premises as foundations: that cultivating virtues and strengths will make us happy and that a happy life is a pleasant life, but one that must have meaning [2]. Research on personal strengths within positive psychology materializes in trait theory. Seligman refers to good character as that which is constituted by positive traits, which he calls strengths. The distinctive qualities that, according to Seligman [ 2 ] and Park and Peterson [ 3 ], this good character should comprise a family of positive traits that are manifested in individual differences and that allow the strengths that people possess to be distinguished. These traits are manifested through thoughts, feelings and actions; can change throughout life; are measurable and are influenced by contextual, proximate and distal factors, so that character and its strengths are educable. Educ. Sci. 2022,12, 178. https://doi.org/10.3390/educsci12030178 https://www.mdpi.com/journal/education Educ. Sci. 2022,12, 178 2 of 19 The six universally accepted positive traits, which are also called virtues, are wisdom, courage, humanity, justice, moderation and transcendence. As these virtues are very general and abstract, but are concretized through 24 personal strengths, which are defined as morally valuable styles of thinking, feeling and acting, which contribute to a life in fullness [4]. Seligman [ 2 ] differentiates three aspects that are present in the concept of happiness: pleasure, commitment and meaning. For people to be happy, they must guide their lives towards the balance of these three aspects, especially the last two [ 5 , 6 ]. Subsequently, he added two more aspects to this model of well-being, achievements and interpersonal relationships, to create the PERMA model [ 7 ] of positive emotions, engagement, relationships, meaning and achievements. These aspects give happiness an internal and social nature. Happiness, in the scientific approach of positive psychology, is considered “subjective well-being”, which includes two components: the emotional and the cognitive [8]. Happiness or well-being and personal improvement are inseparable processes. Seligman [ 2 , 7 ] states that to be happy, we need to develop personal strengths and capacities with which to enjoy things and achieve the necessary balance and satisfaction in life. Fordyce [ 9 ] was the first to develop a project for teaching happiness; based on the scientific literature, he recognized 14 qualities associated with happiness. We present the counts and definitions of the virtues and character strengths, according to Seligman and Peterson (Table 1): Table 1. Virtues and strengths of character according to Seligman and Peterson. VIRTUES STRENGTHS 1Wisdom and knowledge 1Curiosity, open to experience, interest in the world 2Love of learning 3Open-mindedness, judgement, critical thinking 4Creativity, originality, practical intelligence, insight 5 Perspective 2Courage 6 Bravery 7Persistence, industry, perseverance 8Integrity, authenticity, honesty 9Vitality, enthusiasm, energy, passion, zest 3Humanity 10 Kindness, generosity, compassion, altruistic love, kindness, caring 11 Love 12 Social intelligence, personal intelligence, emotional intelligence 4Justice 13 Citizenship, social responsibility, loyalty, teamwork 14 Impartiality and equity 15 Leadership 5Temperance 16 Forgiveness, mercy 17 Prudence, discretion, caution 18 Humility and modesty 19 Self-control 6Transcendence 20 Appreciation of beauty and excellence 21 Spirituality, purpose, faith, religiosity 22 Gratitude 23 Humour and playfulness 24 Hope, optimism, foresight Positive psychology encourages education professionals to become better able to help people increase their well-being and flourish. This translates into improving people’s quality of life and subjective well-being and developing their competencies [ 10 ]. According to this author, common elements of positive psychology, such as well-being and the development of strengths, among others, should be integrated into the mandatory academic curriculum. Different programmes and experiences of positive psychology are applied in education, such as “Bounce Back!” [ 11 ]; the “Celebrating Strengths Programme” [ 12 ]; “Strengths Gym” [ 13 ]; the “Affinities Programme” or “Strong Planet” [ 14 ] and “SMART Strengths” [ 15 ] in the United States and the “Programa de promoción del desarrollo personal y social” [16,17], Educ. Sci. 2022,12, 178 3 of 19 the “VIP Programme” [ 18 ] and the Handbook of Positive Psychology in Schools [ 19 ] in Spain. We opted to apply the Peterson and Seligman model of happiness to education in our research because it is a global model, with important theoretical and empirical support, and because it can be applied in the educational field. Positive education is born of positive psychology’s study of the optimal functioning of the human being in educational contexts [ 20 ]. It is supported by research on emotions in teaching and learning processes [21–26]. Because it is practically impossible to develop all of a student’s strengths, as many characteristics as possible should be improved, as should others that are less innate, when possible. As indicated by Reivich et al. [ 27 ] and Seligman [ 2 ], by improving personal qualities and skills and social contexts through the fostering of resilience and well-being, character strengths are cultivated, and positive emotions and relationships are experienced. Education in the arts seeks to encourage the student’s autonomy in their learning process and connect them with the world through its affective and cognitive components [ 28 ]. Its affective component makes the arts different from scientific thought and its influence on curricula, thereby adding value to general education. In addition, a work of art in itself can evoke perplexity, mystery or confusion that creates enormous cognitive demand and encourages intellectual research [29]. There is a body of literature that links the arts in education with positive psychology, demonstrating that it develops fundamental strengths for achieving eudaemonic happiness and subjective well-being [ 30 , 31 ]. There are countless antecedents of studies of artistic projects that seek eudaemonic happiness and the well-being of their participants, such as the Sing Up Programme in the United Kingdom [ 32 ] and studies in educational centres in Canada [ 33 ], in youth orchestras in Argentina [ 34 ] and in the Venezuelan system and the projects it has inspired [35,36]. We, thus, recognize a confluence of positive education with emotional education in the arts that contributes to the personal and social well-being of the individual and develops students’ integral personalities, enabling them to face daily challenges by working with values [ 37 ]. Additionally, training autonomous individuals who can adapt to the changes and needs of the new labour market has led to concerns about education at the international level. This is how the OECD came to create the DeSeCo project [ 38 ]. In this project, school curricula are reformulated around the concept of competencies. A series of Key Competencies are created that serve as a reference for the educational systems of the member countries and through which the individual is responsible for his or her learning, moving from being a consumer of knowledge to a builder of it, a process that strengthens students’ overall development [39]. To clarify this relationship, the Key Competencies of the European Union and the character strengths that could be included in and/or developed through them are compared (Table 2). Table 2. Comparison between the Key Competencies of the European Union and the character Strengths described by Seligman and Peterson. Key Competencies of the European Union Character Strengths 1.

Cultural awareness and expression 1, 3, 4, 5, 12, 13, 20, 21 Educ. Sci. 2022,12, 178 4 of 19 Research, such as that of Miller, Dumford and Johnson [ 40 ], provides evidence that the arts are fundamental and foster the acquisition of professional competencies that students will use in their day-to-day lives and that are necessary in social settings. The connection between emotion and attention is vital, and it seems that art is one of the most reliable and interesting methods for developing competencies, since it has been demonstrated that there is a relationship between attention and the emotional world [41]. In a previous mapping, we observed that there are already systematic reviews dedicated to three coexisting competencies: social and personal, professional and methodological [ 42 ]. There are also two meta-analyses that cover the areas of social and emotional competencies, but none that relate competencies with all of the strengths in the field of arts education [43,44]. At this point, we intend, through this literature review, to demonstrate the relationship between the Key Competencies as catalysts for the development of character strengths in students through art programmes in education. 2. Systematic Review Methodology A systematic review of the literature was developed for which we used the PRISMA model as a framework [ 45 ], adapting the checklists of the CASP model [ 46 ] in the Web of Science (WOS) and Education Resources Information Center (ERIC) databases. Before carrying out the systematic review, we verified the validity of these models by performing a search in WOS with the terms Review, PRISMA, CASP and Education for the last 5 years. We obtained articles such as the study by Gow, Mostert, and Dreyer [ 47 ] that legitimize the use of CASP in the PRISMA model for our systematic review using the WOS and ERIC databases. 2.1. Identification. Search Terms To identify the search terms, we used the PICo criteria [ 48 ] on the basis of their reliability, as determined by keyword searches based on the PICo elements: participants, interventions and comparators. • Participants: Children, youth and adult students in primary, secondary and university education in formal, nonformal and informal education fields and in settings with low, medium and high social involvement. •Intervention: ◦Arts in education studies linked to character strengths. ◦Positive education studies related to the arts in education. ◦ Studies of the relationship between the Key Competencies and an operational breakdown of the character strengths of positive education in the context of the arts. • Comparators: In terms of the search, we considered alternative interventions that contextualized the search within positive education in the arts. To organize our search, we classified the terms in relation to four constructs: positive psychology, education, arts and the Key Competencies. For each construct, we considered the following search terms: Positive psychology (Character Strengths, Values in Action, Positive Psychology, Eudaemonic Happiness, Happiness, Wellbeing, Well-being, Eudaemonic Wellbeing and Wellness), education (Education and Positive Education), Arts (Arts, Arts-Based Education, Education through Arts, Arts Education, Artistic Education, Arts in Education and Arts-Based Programmes) and the Key Competencies (Competencies, Skills, Key Competencies, Educational Competencies, Emotional Competencies, Social Competencies, Cognitive Competencies and Basic Skills). Each of the search terms included in these constructs was combined with the others. By combining the nine terms related to positive psychology, the two terms related to education, the seven terms related to the construct of arts in the educational context and the Educ. Sci. 2022,12, 178 5 of 19 eight search terms related to the Key Competencies, we performed a total of 1,008 searches in each database (WOS and ERIC) using the Boolean operator AND. The result of these searches was 50 articles in the WOS database and 48 references in ERIC, of which 43 were articles and five were books. Each article was coded to obtain information on the type of sample. An ID was assigned to each article with the letter W or E, depending on the database where the article was found (WOS or ERIC, respectively). This screening required a subsequent analysis of the potential synonyms and alternative terms that appeared in the included articles. In the case of the constructs “character Strengths” and “key Competencies”, they are not always studied explicitly, but implicitly. Although the explicit treatment of the constructs in the articles is preferable to the implicit treatment, the interpretation of the implicit concept lies in the relationship and how it is defined by the reader [49]. It is interesting to analyse how the terms used in the different articles describe the constructs that are the object of our study, that is, how researchers have referred to the constructs to define them or to specify the relationships among them. To this end, we present the theory of Murphy and Alexander [ 49 ] regarding the explicit or implicit definitions of the construct through the terms used by the authors of the articles. This multiplicity of terminology used to define the constructs, citing Murphy and Woods [ 50 ], occurs because lexicons are developed as the members of a certain community label and define constructs. The way that constructs are labelled or named is fundamental for the development of theories, which must be clarified to create a perfect definition of both the constructs and the terms that define them. In the case of the social sciences, specifically education, as expressed by Dinsmore, Alexander and Loughlin [ 51 ] citing Alexander, Schallert and Hare [ 52 ] and Murphy and Alexander [ 49 ], there is a lack of clarity and linguistic specificity in educational literature, where lexicons can be amorphous and open to interpretations that can lead to a misinterpretation of the construct. This can, as the authors explain, be the result of wanting to use terms with the expectation that their meanings are well known and accepted or without considering the thoughts underlying them or the understandings that have resulted from their imprecise use. In our research, we observed that, because neither positive psychology nor the Key Competencies have a very extensive trajectory, professionals from different fields of research have contributed to these trends in psychology and education by borrowing terms and findings from their respective fields of research, introducing related terminologies that can lead to ambiguities when defining a construct. 2.2. Screening Before the exclusion and inclusion criteria were applied, articles that were duplicates (n= 8) or were written before 2016 (n= 4) were eliminated using Microsoft Excel software. Of the 98 initial references, 86 remained. 2.3. Eligibility 2.3.1. Inclusion and Exclusion Criteria Inclusion criteria •Pragmatic criteria: ◦Languages: English and Spanish. ◦Studies in student population among children, youth and adults. ◦ That the research of the articles be carried out in the formal school environment (Primary and Secondary or in the equivalent of other countries), university, adult training and in non-formal and informal environments. ◦Publication date: Articles published after 2016.

Review Phases. Traceability We applied the inclusion and exclusion criteria in four phases: 1. Studies in languages other than English or Spanish were excluded (n= 4). Of the 86 references, 82 remained; 40 were identified in WOS, and 37 were identified in ERIC, of which 32 were articles, and five were books. 2. We proceeded to read the abstract. During this process, we screened the studies that were directly related to the four constructs under study. During this step, 37 articles and four books were eliminated. The remaining references continued to the next screening step (26 were from WOS and 14 from ERIC, of which 13 were articles, and one was a book). 3. We read the full text of the 37 references, of which one was a systematic review that we have included for its investigative value. To ensure the eligibility of the included references, we applied the CASP checklist to each selected article and to the different stages of our systematic review. 4. Eight articles and one book were eliminated because they did not address the relationship among the four constructs, leaving 27 articles, of which 16 were found in WOS, and 11 were found in ERIC. 5. In this last phase, which initially included the 27 references that were related to the four study constructs, 14 references obtained conclusions that answered our research question; eight were selected from WOS, and six were selected from ERIC. The remaining 13 articles (eight from WOS and five from ERIC) partially answered our question. Therefore, our study and analysis of the results focused on the first group of 14 articles. We present a summary of the selected articles included in our systematic review with their IDs, title, authors, year of publication, type of document, journal or book, where the study was published, in addition to the age, gender and educational level of the participants, the research methodology and source of data for the paper (Table 3).

Results The results that we present confirm the relationship between the Key Competencies and the development of character strengths in students through art programmes in education. In global terms, the Key Competencies have been linked to character strengths, although the terminology used by researchers has not always been explicit. Educ. Sci. 2022,12, 178 16 of 19 With respect to Virtue 4 (justice), it was not possible to find a clear link between Competency 1 (communication in mother tongue) and Strength 14 (impartiality and equity). For Virtue 5 (temperance), we highlight that Strength 19 (self-control) was barely linked to the Key Competencies, with the exception of Competencies 5 (learning to learn) and 7 (sense of initiative and entrepreneurial spirit). For Virtue 6 (transcendence), no links were found between Strength 21 (spirituality, purpose, religiosity) and Competency 4 (digital competence) or between Strength 24 (hope, optimism) and Competency 3 (mathematical competence and basic competence in science and technology). The weaker presence of the strengths associated with Virtue 2 (courage and temperance) is noteworthy. Specifically, no links were found with Strengths 6 (courage), 7 (persistence, industry) and 9 (vitality, enthusiasm). Thus, we can conclude that the competencies that can be worked on in positive education through the arts would hardly develop these strengths. Practical and Academic Implications and Recommendations for Future Research From a practical point of view, the conclusions from our research allow us to make decisions to start a field of research that deepens the relationship of the Arts in education, from the perspective of Positive Education and Key Competencies. The Arts in Education becomes the tool to link Character Strengths with Key Competencies. This contribution of the Arts develops in the student the Competences and Strengths necessary to face the constant changes that are generated in the current professional panorama. In addition, we believe that different possibilities are opened for other researchers to delve into this still little explored field, in which we consider the application of validated tools with a greater scientific nature to be very necessary. It should be added that a significant number of articles in our systematic review point to the lack of studies that apply the scientific method with greater rigour, so that a consistent reference framework can be consolidated. This is an element that we corroborate after the analysis and interpretation of this systematic review. Based on our study, and after demonstrating the link between Character Strengths and Key Competencies, future research may deepen this link in the educational field of the Arts, as the foundation of sustainable human development. Since the Key Competencies are the pillar that UNESCO uses for Education for Development, this human development can be better evaluated thanks to the measurement of Character Strengths. From the academic point of view, our SR has also made it possible to integrate the existing literature that, up to now, has attempted to address separately the different constructs that are the object of our research. With our study, we have been able to bring together the four constructs in a single research object. Even when the articles and studies of our research seem to connect the constructs separately or implicitly, we need a larger corpus of studies that brings together the four constructs to be able to demonstrate our hypothesis more solidly. Another type of research design would also be necessary. Future studies should apply adequate designs that include both the random assignment of participants and an active control group. Such a design would allow the empirical evaluation of whether these connections are efficient and will endure. 6. Limitations and Recommendations In our study, we observed two important limitations. The first is that the constructs of this research belong to very diverse areas, such as psychology, education and the arts, and the researchers in each of these areas define the other constructs by importing the terms used in their own fields. This results in a lack of conceptual clarity that affected the search terms used and the criteria used to establish them, since it would have been necessary to use an excessive variety of terms to conduct an exhaustive search. Following the steps of Educ. Sci. 2022,12, 178 17 of 19 Murphy and Alexander [ 53 ], the choice of our search terms considered the breadth and overlap of constructs to allow for a certain degree of efficiency. We could define this limitation as a lack of specificity when defining the constructs or, in other words, the excessive number of synonyms that are attributable to a particular construct. As previously indicated by authors, such as Dinsmore, Alexander and Loughlin [ 51 ], this may be due to two reasons: The first is because the construct is defined by authors who are not familiar with it or who do not regard it as its own entity, or because authors define constructs using terms from their own professional field. In this way, the researcher defines characteristics and qualities inherent to the constructs that we systematized in our systematic review. This excess of terminology, which has resulted from a need for a definition that serves all specialties, led us to broaden the search terms that we used for this systematic review and to consider implicit definitions of those constructs that were studied, with or without the express desire of the researcher. The second limitation, which is derived from the previous limitation, is the ambiguity that can be generated by the use of a given term to define a strength or a competence. That is, the breadth of interpretations and definitions of one or several strengths or competencies can be covered by a single term. This possibility of relating a concept that appears in an article with one or more strengths and/or competencies can, a priori, generate certain limitations in the search for relationships among strengths and competencies. We are aware, on the other hand, of other limitations of our research, such as the selected languages (only English and Spanish), the omission of a bibliometric review and not having considered other databases.
