Predicting Intercultural Communication in Malaysian Public Universities from the Perspective of Anxiety/Uncertainty Management (AUM) Theory

: The mission to promote national unity has become more strenuous with the decline of intercultural engagement among multicultural students in Malaysian public universities. Underpinned by Anxiety/Uncertainty Management (AUM) theory, this article examines barriers to intercultural communication by integrating ethnocentrism as an additional barrier. Based on a quantitative approach, 449 valid responses were collected from undergraduates from five public universities in Malaysia. Partial-least-squares software (SmartPLS3) was used to test the proposed relationships. The findings reveal that anxiety, uncertainty, and ethnocentrism have a significant negative relationship with intercultural communication.


Introduction
Malaysia is one of the most multicultural countries in Southeast Asia (Azlan, Kee & Abdullah 2018) with three major ethnic groups: Malay, Chinese and Indian (Chang & Kho 2017). Since its independence in 1957, Malaysia has always been struggling to introduce concepts able to promote "unity in diversity" to form a national identity (Yusof & Esmaeil 2017). Although education policies are expected to play the key role in fostering national integration, existing studies indicate that intercultural communication in higher education institutions is still limited and not up to satisfactory level (Tamam 2013;Tamam et al. 2013) To worsen the situation, most university students prefer socializing with their friends and peers from the same ethnic group (Hashmi et al. 2017). Instead of being an avenue for uniting students, Malaysian public universities are in danger of being breeding grounds for intolerance, ethnocentrism, and segregated communities (Mustapha et al. 2009).
There is considerable evidence that intercultural communication often creates chaos among higher-learning-institution students coming from diverse cultural backgrounds (Holmes 2005). Uncertainty is considered to be the primary factor that affects intercultural communication (Novinger 2001). Neuliep (2015) explains that communication with someone from a different cultural background can be frightening and can be worsened by uncertainty. A concept that is strongly associated with uncertainty is anxiety. Interaction with people from a different culture often leads to anxiety, which sometimes causes individuals to avoid initiating interaction (Logan, Steel & Hunt 2015).
Underlying the present research is Bill Gudykunst's (1995) Anxiety/Uncertainty Management (AUM) theory. AUM theory identifies uncertainty and anxiety towards other cultures as playing a major role in intercultural communication. According to Gudykunst, to communicate effectively, people from different cultural backgrounds try to lessen anxiety and, at the same time, improve certainty about themselves and the other person. establishing integration in a nation whereby local and neighbourhood settings are the starting point for integration processes. Intercultural communication is essential in strengthening the bonding among people from different cultural backgrounds and helping them to take part in the global community.
Life, culture, communication and national integration are ongoing, evolving processes without precise beginnings or endings (Dada & Babatunde 2015). A country relies heavily on intercultural communication for its development given the consequent ability to share ideas internationally and also between people of varied cultural backgrounds within the same country. For Singh (2016), intercultural communication is an important component establishing social harmony; it plays a significant role establishing the link between two or more persons or ethnicities of one culture and another, or of one society and a nation. Singh writes that, by promoting intercultural relationships through intercultural communication, world views of diverse cultural communities are enhanced.
As a leading institution for socialization, higher educational shapes each new generation's world perspectives through its role as a platform for establishing new contacts

Relationship of uncertainty to intercultural communication
Uncertainty refers to a lack of information as to how one should act to expect certain outcomes (Aspers 2018). Communication with someone from an unknown culture can be terrifying and worsened by uncertainty (Neuliep 2015), causing inability to predict or explain the events that transpire in and around social communication (Whitt 2015). Neuliep (2015) states that, due to the difficulty predicting a stranger's responses, it is common to experience a higher degree of uncertainty while communicating with an individual from a different culture. Intercultural encounters seek to lower the degree of uncertainty to improve the ability to predict and understand a stranger from a different culture (Redmond 2015) by gaining more information about the person (Ihtiyar 2018). When people fail to gather more information, it becomes more difficult for them to predict or explain the other's behavior. This leads to uneasy feelings, and intercultural communication becomes ineffective or avoided (Presbiteroa & Attar 2018). A limited number of studies have been conducted in Malaysia regarding uncertainty. Ismail's (2015) study on intercultural communication among multicultural university staff reveals that 92% of the respondents felt uncertain during interactions with colleagues from differing cultural backgrounds. Tamam and colleagues (2013) state that doubts among students over whether or not another cultural group is interested in intercultural engagement is taken as uncertainty. They reason that there is need to investigate the influence of uncertainty in intercultural communication among Malaysian undergraduates. We suggested that: H1: There is a relationship between uncertainty and intercultural communication among Malaysian undergraduates.

Relationship of anxiety to intercultural communication
A high degree of uncertainty triggers high anxiety among communicators (Neuliep 2015). Anxiety often presents with complex behaviors that impede effective communication (Ilie 2019). In an unfamiliar situation, people feel anxious because of not knowing what they should say or do. Especially when people are in a new environment, language barriers and insufficient knowledge about the new culture cause difficulty adapting (Khatimah 2019), which make people feel that they are losing all their familiar signs and symbols of social intercourse (Wu, Garza & Guzman 2015). When people have more in common with others, they are more comfortable getting along (Ilie 2019). Bucker and colleagues (2014) observe that intercultural interactions can threaten people as they realize that assumptions they had during interactions with those from their own culture are not applicable when communicating with those from a different culture. A feeling of losing ground often leads to anxiety.
Studies in Malaysia have focused on anxiety in intercultural communication between local and international university students (Ahmad et al. 2017, Khojastehrad & Sattarova, 2015, second-language anxiety (Manan & Shamsudin 2017, Miskam & Saidalavi 2019, and anxiety in intercultural communication between university staff and international students (Mandayar 2011, Misni 2014. There is only one study, conducted by Jaganathan and Kaur (2003), which investigates the impact of anxiety on intercultural communication among multiracial high-school students aged 19-20 years. To the best of our knowledge, there is no empirical study investigating anxiety among multiracial undergraduates in intercultural communication settings. The current study is intended to bridge the gap. We suggest that: H2: There is a relationship between anxiety and intercultural communication among Malaysian undergraduates.

Relationship of ethnocentrism to intercultural communication
High levels of anxiety and uncertainty lead to an ethnocentric attitude (Liu, Volcic & Gallois 2014). Sumner (1906: 13) coined the term "ethnocentrism" defined as "the technical name for this view of things in which one's own group is the centre of everything, and all others are scaled and rated with reference to it". Although a certain level of ethnocentrism is necessary to establish solidarity within a group, an excessive level leads to prejudice and discrimination (Neuliep 2012). Neuliep (2012) examined the relationship between anxiety, uncertainty, and communication satisfaction during initial intercultural interaction. The results demonstrate that uncertainty reduction becomes difficult due to ethnocentrism and anxiety. Tegelaar (2012) investigated the relationship of anxiety and ethnocentrism to willingness to communicate with homeless people. Their findings show the European respondents to be more ethnocentric than the American or Mexican participants. The negative relationship between ethnocentrism and intercultural communication is supported in further studies (e.g., Arasaratnam & Banerjee 2011, Robinson 2017.
Although many studies related to ethnocentrism are available in Western countries, only very limited studies are available in Malaysia. This study aims to examine the relationship of ethnocentrism to intercultural communication. We theorize that: H3: There is a relationship between ethnocentrism and intercultural communication among Malaysian undergraduates.
The framework for this study is based on Gudykunst's (1995) Anxiety/Uncertainty Management theory with its two barriers on intercultural communication: anxiety and uncertainty. Ethnocentrism, a concept introduced by Sumner (1906), is incorporated as another determinant, for a total of three independent variables. See Figure 1.

Participants and sampling
For this study, respondents comprise Malay, Chinese, and Indian undergraduates studying at one of five research universities in Malaysia: Universiti Malaya (UM), Universiti Sains Malaysia (USM), Universiti Putra Malaya (UPM), Universiti Kebangsaan Malaysia (UKM), and Universiti Teknologi Malaysia (UTM). The main reason for selecting public universities rather than private is the access to a high number of multicultural students.

Survey procedure
Respondents were selected by proportionate stratified sampling. The number of questionnaires distributed to each university was proportionate to each university's undergraduate population. Sampling was determined based on the sample-size table from Krejcie and Morgan (1970: 608). Sekaran and Bougie (2016) cite that table as a guideline to deciding sample size. Since the total undergraduate population in the five universities was 89,310 at the time of data collection, the minimum sample size for the present study was determined to be 382.
This paper intended to achieve a minimum response rate of 80% based on response rates obtained in past studies (Awang-Rozaimie et al. 2017, Yunus et al. 2017. Therefore, to obtain 382 responses, 477 questionnaires were distributed. Due to privacy laws and regulations as well as the universities' own policies, the universities refused to disclose information related to ethnicity, gender or age. That made it impractical if not impossible to recruit respondents according to ethnic proportion of the university population. Therefore, this study used the overall ethnic breakdown of the Malaysian population, which is approximately 6:3:1 (Malay, Chinese, Indian). This meant that 286 questionnaires were distributed to Malay respondents (60%), 143 to Chinese respondents (30%), and 48 to Indian respondents (10%). Respondents were selected using probabilistic systematic sampling: every third student who entered each university's main library was approached and asked to answer the questionnaire. Questionnaires were collected immediately once completed. We received 449 usable questionnaires, yielding a success rate of 94.1%.

Measures
Intercultural communication was measured with a seven-item scale proposed by Ketab and colleagues (2015) extracted from the Your First College Year YFCY survey.
Uncertainty was measured with Clatterbuck's (1979) Attributional Confidence Scale, which consists of seven items. The original scale required respondents to indicate their certainty level in percentage for each item, ranging from 0 (not confident at all) to 100% (fully confident). Following a suggestion from Baruh and Cemalcilar (2018), to maintain uniformity throughout the questionnaire, the present study changed the items from questions to statements and used a five-point Likert scale instead.
For the purpose of measuring anxiety level among respondents, the Personal Report of Intercultural Communication Apprehension (PRICA) Scale developed by Neuliep and McCroskey (1997b) was adopted and modified. The original scale consists of 14 items measuring anxiety towards strangers, seven measuring relaxed feelings, and seven measuring anxiety. For the present study, only those seven measurement items related to anxiety were used.
Ethnocentrism was assessed with five items from Neuliep and McCroskey's (1997a) Generalized Ethnocentrism (GENE) Scale. The original scale consists of 22 items. For the present study, only five items were used, based on suggestions from a previous study conducted in Malaysia (Ketab et al. 2015).
All 26 items were measured on a five-point Likert scale from 1 ("strongly disagree") to

Descriptive analysis
The respondents comprised 271 (60.4%) Malay, 134 (29.8%) Chinese, and 44 (9.8%) Indian undergraduate students, of whom 76.6% were female and 23.4% male. They represented all years of study: 186 (41.4%) first-year students, 105 (23.4%) second-year, 149 (33.2%) thirdyear, and nine (2%) fourth-year. Frequency analysis revealed that the majority of respondents (62.4%) reported having intercultural communication on a daily basis. Of the remaining, 21.6% indicated a frequency of three to five days per week, 8.7% one to two days, and 7.3% "rarely". No one reported "never". This implies that students in the university setting are unable to escape from participating in intercultural communication. Khumsikiew, Donsamak, and Saeteaw (2015) write that, for a five-point Likert scale, mean scores can be interpreted as very low, low, moderate, high, and very high for scores ranging 1.00 to 1.80, 1.81 to 2.60, 2.61 to 3.40, 3.41 to 4.20, and 4.21 to 5.00, respectively. Table 1 summarizes how respondents showed low anxiety (mean = 2.40, SD = .78), moderate uncertainty (mean = 2.73, SD = .52), low ethnocentrism (mean = 1.87, SD = .79), and high intercultural communication (mean = 3.54, SD = .65). Table 2 shows mean values based on ethnicity.  The Indian sample had the highest mean value for intercultural communication (3.62, SD = 0.63), followed by the Malay sample (3.55, SD = 0.67), and the Chinese sample (3.50, SD = 0.61). These means tracked the mean values for each barrier. The Malay respondents had medium mean values for all three barriers (and consequently for intercultural communication overall); the Chinese respondents had the highest mean value for anxiety and ethnocentrism but the lowest mean value for uncertainty; while the Indian respondents had the highest mean value for uncertainty but the lowest mean values for anxiety and ethnocentrism. As the Indian respondents were mainly affected by one barrier (uncertainty), they had the highest mean value for intercultural communication, while the Chinese had the lowest (3.50, SD = 0.61), being significantly affected by two barriers: anxiety and ethnocentrism.
Female students constituted the highest number of respondents. This reflects the true composition of students in the chosen public universities. As Tienxhi (2017) notes, most public universities in Malaysia fall within the extreme-disparity classification with a Gender Parity Index (GPI) above 1.5, which means that females outnumber males by a ratio of more than 1.5. Given the gender disparity, a T-test was used to find out if there was any significant difference in the mean values scored by male and female respondents. No such difference was found, either for intercultural communication overall or for any of the three barriers.

Assessment of the measurement model
Confirmatory factor analysis (CFA) was performed to examine discriminant validity, convergent validity and reliability to assess the measurement model. Based on the rule of thumb from Hair and colleagues (2017), three items were omitted from the measurement model due to low factor loading less than 0.5 (UNCT1, UNCT2, and IC1). Table 3 shows the remainder of the item loadings. All the composite reliability (CR) values exceed 0.7, indicating adequate acceptable reliability per Hair and colleagues. For average variance extracted (AVE), Hair and colleagues suggest that values must be 0.50 or higher, to show that the variable explains more than half the variance of its indicators. All our AVE values are above 0.5.

Assessment of the structural model
To use SmartPLS3 in hypothesis testing, two compulsory analyses should be carried out: the coefficient of determination (R2) to quantify the endogenous constructs and the path coefficients (Hair et al., 2017). It is important for the path coefficients to be significant, whereas R2 can vary depending on the research area. Chin (1998) describes the R2 values of 0.19, 0.33 and 0.67 in the path model as weak, moderate and substantial, respectively. As shown in Figure 2, we found an R2 for intercultural communication of 0.235, which is moderate. This means that the influence of uncertainty, anxiety, and ethnocentrism towards intercultural communication is 23.5% only, with the remaining 76.5% determined by other variables.

Hypothesis testing
As shown in Table 5, all independent variables --uncertainty, anxiety, and ethnocentrism -were found to have a significant influence on and negative relationship with intercultural communication.
Uncertainty has a significant negative effect on intercultural communication (β = -0.352, t = 8.744, p = 0.000), supporting H1: uncertainty is negatively associated with intercultural communication among undergraduates in Malaysian public universities. It impedes interaction with peers from different cultures.
Similar to uncertainty, anxiety has a significant negative effect on intercultural communication (β = -0.202, t = 3.071, p = 0.002), supporting H2: anxiety is negatively correlated with intercultural communication among undergraduates in Malaysian public universities. When students face higher anxiety, it results in low intercultural communication among peers from different cultures.

Discussion
This study was carried out to determine the nature of relationships between anxiety, uncertainty, and ethnocentrism and their effect on intercultural communication among Malay, Chinese, and Indian undergraduate students at five Malaysian universities. This study is the first of its kind to do so.
The results for the first hypothesis show a significant negative relationship between uncertainty and intercultural communication among Malaysian undergraduates. This finding supports previous studies that revealed uncertainty as a barrier to intercultural communication (Gudykunst 1995;Logan et al. 2015Logan et al. , 2016Logan et al. , 2017Neuliep 2012;Whitt 2015). Presbiteroa and Attar (2018) explain that, when people fail to gather more information about an individual who comes from a different cultural background, it becomes more difficult for them to predict and explain the individual's behavior. This leads to uneasy feelings, and intercultural communication becomes ineffective.
The results for the second hypothesis show a significant negative relationship between anxiety and intercultural communication among Malaysian undergraduates. This finding supports previous studies that revealed anxiety as a barrier to intercultural communication (Gudykunst 1995, Ilie 2019. Individuals experience anxiety due to insufficient knowledge about an environment and its culture, making them feel like they are losing all their familiar ground (Khatimah 2019; Wu, Garza & Guzman 2015). This feeling can be controlled if sufficient information related to the intercultural setting is available (Chen & Yang 2015).
Finally, the results for the third hypothesis show a significant negative association between ethnocentrism and intercultural communication. Again, past studies have reported similar results, agreeing that ethnocentrism impedes intercultural engagement (Cargile & Bolkan 2013, Hooghe & Quintelier 2013, Jandt 2013, Ketab et al. 2015. Due to uncertainty and anxiety, students may choose not to interact at all, which may eventually make them ethnocentric (Campbell 2016).

Conclusion
The findings of this study directly support the AUM theory, which claims that both anxiety and uncertainty are barriers to intercultural communication (Gudykunst 1998, Gudykunst & Nishida 2001, while indicating the relevance of AUM theory in the Malaysian context. Ethnocentrism was found to be another factor influencing intercultural communication. Although all the independent variables were found to have a significant negative relationship with intercultural communication, uncertainty has a stronger influence compared to anxiety and ethnocentrism. As indicated by Neuliep (2015), a higher degree of unfamiliarity and uncertainty triggers high levels of anxiety among communicators. To avoid that anxiety, individuals may choose not to interact with people from differing cultural backgrounds. Our findings show that uncertainty is the root cause of unsatisfactory intercultural engagement among Malaysian undergraduates. This aligns with Neuliep (2015), who views uncertainty as the primary factor affecting intercultural communication. By lowering uncertainty, anxiety and ethnocentrism should also be lowered and intercultural communication fostered. This study delivers clear insight for the management of Malaysian universities to enhance intercultural communication among undergraduates, leading to a better and more harmonious living environment for all.
The findings suggest several practical implications for educators and university management. Institutions of higher education should provide more opportunities for multicultural students to get involved in intercultural activities. The Ministry of Higher Education should consider introducing more Malaysian culture-related courses for undergraduates on top of the existing ethnic-relations course. This will equip students with more knowledge about and better understanding of the other cultures and peoples of Malaysia. Students will be aided in experiencing positive intercultural communication, which should eventually help them to manage their anxiety, uncertainty, and ethnocentrism at an appropriate level. When students encounter different ideas, views and cultures, they can get a better exposure to the other culture(s), which should assist them in establishing more effective intercultural relations later on.
