International or global psychology is an emerging branch of psychology that focuses on the worldwide enterprise of psychology in terms of communication and networking, cross-cultural comparison, scholarship, practice, and pedagogy (Stevens & Gielen, 2007). Often, the terms international psychology, global psychology, and cross-cultural psychology are used interchangeably, but their purposes are subtly and importantly different: Global means worldwide, international means across and between nations, cross-cultural means across cultures. In contrast, the term “multicultural” is more often used to refer to ethnic and other cultural differences existing within a given nation rather than to global or international comparisons.

Definitions and scope[edit]

International psychology is concerned with the emergence and practice of psychology in different parts of the world (Stevens & Gielen, 2007). It advocates committed involvement in worldwide and regional psychology and policy-making organizations such as the International Union of Psychological Science (IUPsyS includes 87 national psychology associations and more than 20 international/regional associations), the International Association of Applied Psychology (IAAP), the International Association of Cross-Cultural Psychology (IACCP), the International Council of Psychologists (ICP), the European Federation of Psychologists’ Associations (EFPA: it includes 36 national psychology associations), the Sociedad Interamericana de Psicología (SIP), the recently founded Pan-African Psychological Union (PAPU), and others. The goal is to establish psychology as a global discipline that in its theories, research practices, applications, and ethical aspirations is focused on the psychological study of humanity as a whole while avoiding as much as possible ethnocentric biases and preoccupations (McCormick & Constantable, 2015; Stevens & Wedding, 2004). For an annotated bibliography on international psychology that covers 156 publications, see Takooshian, Gielen, Rich, and Velayo (2016).

In contrast, the term “global psychology” is more frequently used to refer to the worldwide investigation of global issues and phenomena from a psychological and psychocultural point of view. Examples include the investigation of subjective well being, identification and treatment of mental health problems, the psychological dimensions of family systems, gender roles and gender-typed behavior, childrearing practices, cognitive and emotional functioning, international attitudes, value systems, intergroup conflicts, threats to the natural environment, societal transformation and national development, the struggles of disempowered groups (such as women, children, immigrants, and refugees) as seen in a global perspective (Stevens & Gielen, 2007).

Cross-cultural psychology may be defined as the comparative study of behavior and mental processes in different cultures. It aims to measure the psychological phenomena across cultures and looks for patterns, generalizability, and culture-specific differentiation (Shiraev & Levy, 2013). An example would be the investigation of child-rearing practices and their psychological consequences among distinctly different groups. Cross-cultural psychology focuses on the relationship between psychology and culture (such as language, traditions, and socialization practices) and how it affects individual human functioning. In this respect, cross-cultural psychology constitutes one important element of global psychology. Cross-cultural psychology emerged during the 1960s-1970s as a separate field of study with a definite identity; it is thus older than the more general field of international psychology, which is only now emerging as a distinct discipline.

The Oxford English Dictionary (1993) defines global as, “…pertaining to or involving the world, worldwide” (p. 1101) and international as, “Existing, occurring, or carried on between nations…Agreed on by many nations; used by, or able to be used by (the people of) many nations” (p. 1397). At present the term international psychology is in wider use although Stevens and Gielen (2007) prefer the term global psychology, to underline the increasingly global nature of psychological phenomena and problems together with their scientific investigation and efforts to ameliorate them. More generally, the emergence and intensification of an international psychology movement is part and parcel of the broader process of globalization in the economic, technological, sociocultural, political and ecological spheres. It reflects and makes use of the increasingly global flow of information, ideas, and peoples. In addition, globalization in psychology has led to the de facto use of English as the predominant means of communication so that academics in many parts of the world are now expected to read and publish in English-language journals.

It should be added that international psychology, global psychology, and cross-cultural psychology share the common goal of making psychology more universal and less ethnocentric in character. Because American psychologists dominated the field of psychology especially in the decades after World War II, they frequently ignored contributions from other parts of the world and claimed, whether explicitly or implicitly, that their theories, concepts, ethical standards, and empirical findings applied to all—or at least most—people around the world. In addition, because they largely ignored books and journals not written in English, American psychology became a largely monocultural and monolinguistic discipline (Draguns, 2001). Consequently, it is a key goal of internationally oriented psychologists both in the US and elsewhere to turn psychology into a more universally and less culturally biased discipline that contributes to human welfare everywhere while strengthening "world consciouness" rather than ethnocentric and potentially violent forms of nationalism or extremist religious preoccupations (Leong, Pickren, Leach, & Marsella, 2012).


Major foci of international psychology include:

  • The worldwide study of psychological processes and phenomena (e.g., Gielen, 2016; Hofstede, 2001).
  • Macro-level interventions and policy making, for example, international efforts to reduce HIV infections based on psychological research (Wessells & Dawes, 2007), to assess and reduce ethnic conflicts (Landis & Albert, 2013), and to further global mental health (Patel, Minas, Cohen, & Prince, 2014).
  • Micro-level interventions, for example, counseling and psychotherapy, school psychology, and interventions in organizations (e.g., Moodley, Gielen, & Wu, 2013; Pedersen, Lonner, Draguns, & Trimble, 2015).
  • International networking and international psychology organizations and conferences, such as IUPsyS, IAAP, IACCP, EFPA, SIP, APA’s Division 52 – International Psychology, APA's Office of International Affairs, and the Institute for International and Cross-Cultural Psychology (IICCP) (Merenda, 1995).
  • Supporting efforts to internationalize psychology education by infusing global, international, and cultural perspectives into the curriculum, providing international and cross-cultural training experiences, increasing international faculty and student exchange, and forming collaborative research programs (Heine, 2016; Leong et al., 2012; McCarthy, Dickson, Cranney, Trapp, & Karandashev, 2012; Rich & Gielen, 2015; Takooshian, Gielen, Plous, Rich, & Velayo, 2016).
  • Rewriting the history of psychology from a global and less ethnocentric point of view, together with corresponding changes in the curriculum (Baker, 2012; Brock, 2007; Leong et al., 2012; Rich & Gielen, 2015; Takooshian, Gielen, Plous, Rich, & Velayo, 2016).
  • Establishing shared training standards, professional regulations, and codes of ethics (Pettifor, 2007; Leach, Stevens, Lindsay, Ferrero, & Korkut, 2012), such as the Universal Declaration of Ethical Principles for Psychologists (2008), which has been adopted by the IUPsyS and its 87 national member organizations (Leach, Stevens, Lindsay, Ferrero, & Korkut, 2012).
  • Representing psychology at the United Nations especially in the context of non-governmental organizations (NGO's). An important step in this regard was taken in 2012, when The Psychology of NGOs Accredited at the United Nations (PCUN) was established by a group of psychology-based NGOs. These NGOs advocate for the inclusion of psychological perspectives, research, and practice, for instance when formulating and implementing the UN's Sustainable Development Goals.
  • Based in part on the advocacy of psychologists such as Judy Kuriansky, Chair of the Psychology Coalition of NGOs at the United Nations, mental health and well-being have for the first time been included in the UN 2030 Agenda for Sustainable Development. Supported by the World Bank Group and the World Health Organization (2016), mental health specialists are now succeeding in moving mental health issues from the periphery closer to the center of worldwide efforts to improve global health.


Modern scientific psychology had an international dimension from its beginnings in the late 19th century. Wilhelm Wundt (1832-1920), for instance, the father of modern experimental psychology, supervised approximately 190 doctoral students from at least 10 countries. Similarly, the First International Congress of Physiological Psychology in 1889, in Paris, included more than 200 participants from 20 countries (Sabourin & Cooper, 2014). Although psychology developed first in Europe, it soon began to prosper in the United States as well. Altogether, modern scientific psychology remained a predominantly western enterprise till well after World War II although modern psychology was already present in the early 1900s some in nonwestern countries such as India, Japan, and Mexico. During the 1930s many prominent psychologists from Germany and Austria emigrated to the United States. As a result of these developments, psychology in the United States assumed worldwide leadership, but also grew increasingly monocultural, monolingual, and ethnocentric in character (see David and Buchanan, 2003, and Bullock, 2012, for timelines of important events in the history of international psychology). However, there is now an increased awareness among U.S. psychologists that U.S. psychology must take into account global developments in order to fully represent the world of psychology. For instance, the American Psychological Association established in 1997 an International Psychology Division (Division 52), which currently has about 600 members.

During the last three to four decades, especially, psychology has expanded worldwide and assumed a global presence. Stevens and Gielen (2007) estimate that there are over one million psychologists. This estimate is based on local definitions of what it means to be a professional psychologist: in most countries the prerequisite is a Masters degree or Diploma in psychology, whereas in others (e.g., Brazil) a professionally oriented Bachelor’s degree and a period of supervised practice enable one to gain admission to a licensing examination. The global estimate includes well over 320,000 psychologists in Europe, at least 250,000 in Latin America, and 225,000 in the United States. The country with the highest density of psychologists is Argentina. In addition, psychology has gained ground in East and Southeast Asia and is increasingly visible in Muslim countries such as Turkey, Egypt, Jordan, Iran, and Lebanon (Ahmed & Gielen, 1998; Baker, 2012; Stevens & Wedding, 2004). In sub-Saharan Africa, psychology is well developed in South Africa, but less present though expanding in the other regions. For more detailed information, see the edited volume by Stevens and Wedding (2004) which includes analyses of the status of psychology in 27 countries located on all inhabited continents. The handbook by Baker (2012) reviews the respective histories of psychology in 27 countries and regions around the world while the volume by Rich and Gielen (2015) focuses on 17 past and present pathfinders in the realm of international psychology. The contributions respectively to Moodley, Gielen, and Wu (2013) and Gerstein et al. (2009) analyze the status of counseling psychology and psychotherapy in numerous countries.

In general, psychology as a discipline has prospered in well-to-do, urbanized, and individualistic countries and cultures but it is frequently considered an unnecessary luxury in the poorer and more rural regions of the world where the treatment of physical health problems by modern healthcare workers and indigenous healers is likely to take precedence over the identification and treatment of mental health problems (Leung & Zhang, 1995; O'Gorman, Shum, Halford, & Ogilvie, 2012). Such problems are frequently treated by indigenous healers who tend to rely on supernatural explanations for their identification and treatment. However, a global mental health movement that has been strongly influenced by psychiatrists is gathering steam. This makes it likely that in the future, greater resources will be allocated to mental health problems especially in medium-income countries (Patel et al., 2014). Countries where psychology is both influential and especially well developed include The Netherlands, Switzerland, Israel, Germany, USA, United Kingdom, Australia, Indonesia, Austria, the Scandinavian countries, and Argentina (especially psychoanalysis).


Perhaps the best measure of trends within international psychology is within its organizations, through new membership, conference topics, and cooperative research across borders. For example, the International Union of Psychological Science (IUPsyS) has seen an increase of new member countries from Africa, Asia, Eastern Europe, and Latin America in the past 15 years; membership in such organizations represents a desire and need in these countries for networking, training, accreditation, expansion of scientific research, and international recognition (Stevens & Gielen, 2007). Correspondingly, international psychology conferences are now increasingly taking place in both Western and non-Western countries. IUPSyS's quadrennial International Congresses of Psychology (ICP), for instance, have been and will be taking place in Beijing (2004), Berlin (2008), Cape Town (2012), Yokohama (2016), and Prague (2020). Similarly, the quadrennial Congresses of Applied Psychology offered by IAAP, the largest international psychology organization for individual members, have taken or will take place around the globe in cities such as San Francisco (1998), Singapore (2002), Athens (2006), Melbourne (2010), Paris (2014), and Montreal (2018).

Trends in global psychology point to the sustained growth, specialization, and feminization of psychology, and the emergence of contextually sensitive paradigms.

The number of psychologists, psychology students, and psychology programs worldwide continues to grow steadily, proving that one of the goals of globalization is being met. However, much work still needs to be done to bring psychology to underdeveloped areas, and to increase the resources and development of the field in countries where it has already taken hold (Adair & Kağitçibaşi, 1995; Stevens & Wedding, 2004).

Specialization is a growing trend, with each nation focusing specializations on its own needs and goals. Also, communication within these specializations is being facilitated through the World Wide Web and the emergence and growth of specialized international organizations and journals in subfields of psychology. Although access to the Internet is frequently still limited in low-income countries, it has nevertheless improved considerably in recent years thus facilitating the exchange of scientific and professional information as well as research data. The Journal of Cross-Cultural Psychology, for instance, is increasingly publishing papers by large teams of international psychologists that compare psychological phenomena across numerous countries located on all inhabited continents. Moreover, high impact psychological journals published in North America and Europe have broadened their scope by increasingly accepting articles by international and non-Western authors including these residing in East Asian countries.

Feminization in psychology is another trend, as women are beginning to dominate the field in Europe, Latin America, Canada, the United States, and parts of Asia. A trend within this trend is the continued dominance of male psychologists within business and academia, whereas women tend to work more frequently in school, counseling, and clinical settings.

Finally, with the globalization of psychology comes the demand for more culturally sensitive paradigms (Heine, 2016). Traditionally, psychology was taught in the Western context, reflecting the norms, values, and data of those particular regions. Increasing awareness that this psychology does not sufficiently address culturally specific as well as global issues and therefore does not fully apply to some cultures has led to the call for indigenous psychologies, or at least an alternative psychology to the mainstream, reductionistic paradigm which may be applied to most, if not all, cultures (Kim, Yang, & Hwang, 2006). Prominent centers of indigenous psychology include Mexico, the Philippines, South Korea, and Taiwan. Moreover, the increasing inclusion of globally collected data of psychological relevance is gradually undermining the traditionally ethnocentric nature of psychology as taught in the United States and elsewhere in the West (e.g., Hofstede, 2001). Theoretically, indigenous psychologists emphasizing culturally sensitive paradigms tend to see themselves as cultural rather than as cross-cultural psychologists.

Professional regulations and ethical standards[edit]

Many countries around the world have professional regulations for the practice of psychology. “With some exceptions, the existence of professional regulation reflects the level of development of professional psychology in that country. A profession needs to establish an identity and credibility before there is something to be regulated” (Pettifor, 2007, p. 312). In the 36 European countries represented in EFPA, a major effort is underway to unify the basic academic curriculum as well as other requirements underlying the training and certification of psychologists. These countries have established specific yet wide ranging guidelines for a European Diploma in Psychology comparable to a Master’s level university education of six years duration that includes supervised practice. The diploma will enable psychologists trained in one country to practice in other European countries and is likely to influence the education and practice of psychologists in other parts of the world as well.

Countries that currently have no regulation of the profession include India, Iran, Japan, Kenya, Kuwait, Nigeria, Pakistan, the Philippines, Poland, Russia, Singapore, Thailand and Turkey. Several of these countries are working toward licensing legislation, and several have developed ethical standards of practice to guide. Many national psychology associations have adopted a code of ethics such as, for instance, APA’s Ethical Principles of Psychologists and Code of Conduct. EFPA has adopted several codes of ethics in recent years, and the five Nordic countries (Denmark, Finland, Iceland, Norway, and Sweden) adopted a unified code of ethics in 1988, which they revised in 1998 to be more consistent with EFPA’s meta-code (Pettifor, 2007). Moreover, IUPsyS and IAAP adopted, in 2008, a Universal Declaration of Ethical Principles for Psychologists. Such codes and declarations tend to be aspirational in nature.


The scope of scientific psychology and its practice have expanded enormously from its early beginnings in the 19th century to today. This holds true for all post-industrial countries and increasingly for some modernizing nations such as Brazil, China, India, Indonesia, Mexico, the Philippines, and Turkey. In contrast, psychology remains much less visible in the poorer countries and especially so in their rural areas. The expansion of psychology into the nonwestern world has led to an increasing awareness of the role of cultural factors in psychological functioning together with repeated calls to “indigenize” psychology (Kim, Yang, & Hwang, 2006). International contacts among psychologists as well as joint research and applied projects across national and geographic boundaries have prospered thanks to the rapidly evolving technologies of transportation and electronic communication. Consequently, one may safely predict that the cross-cultural, global, and international dimensions of psychology will become more prominent in the foreseeable future.
