6.1 Implications for Theory and Practice
Following design science methodology, we developed a novel online peer-group-based approach and an offline realization to enhance refugee integration. We implemented both the online and the offline realization of the approach in a randomized field experiment to demonstrate the practical applicability of our approach, to evaluate its effectiveness, and to assess the two realizations in a comparative way. The findings contribute to theory and practice in different ways. From a theoretical point of view, they indicate the following three implications.
First, our study provides strong evidence that peer groups provide substantial value to refugee integration in four of five examined domains of integration by Ager and Strang (
2008), i.e.,
social bridges,
social bonds,
rights and citizenship, and
safety and stability. Particularly, our study is the first to establish online peer group effects in the context of refugee integration, by means of a randomized field experiment. First, our study shows that peer groups counteract negative developments in refugees’ attachment to their home and host country which relates to the peer group effect
positive behaviour change. While the control group showed both a slightly significant decrease in
attachment to host country (
p < 0.1) and an (undesired) significant increase in
attachment to home country (
p < 0.05), the online peer groups stayed stable in both of these measures. Studies on online peer groups in other contexts found, for example, an enhancement of participants’ attitude towards career choice through online peer groups and eventually their career search intensity (Klier et al.
2019) or positive effects on participants’ physical activity mediated by change in intention (Cavallo et al.
2014). While those changes in attitude are closely linked to behaviour, findings in our study concern a general attitude towards a country. Second, we observe an increase of refugees’ connectedness to the host country community, i.e., non-peers, which relates to the online peer group effect
intensification of social connectedness (e.g., Goswami et al.
2010; Felgenhauer et al.
2019a). The construct
frequency of contact with people of host culture significantly increased in online peer groups (
p < 0.05) compared to only a slightly significant increase in the control group (
p < 0.1). While former literature shows online peer groups to go along with improved contact with professionals, for example in the context of unemployment (Felgenhauer et al.
2019a),
intensification of social connectedness in our study refers to people of the host country in general. This peer group effect is highly relevant in the context of refugee integration, as social connectedness both represents a central dimension in several integration frameworks (cf. e.g., Ager and Strang
2008; Hynie et al.
2016; AbuJarour et al.
2018; Harder et al.
2018) and is explicitly referred to as a target indicator for ICT interventions in this context (e.g., AbuJarour et al.
2019). In demonstrating this peer group effect, our approach stands out from existing integration interventions as they are frequently criticized for isolating refugees (Mason and Buchmann
2016).
Second, our findings highlight that online and offline peer groups when established in the same context and in a comparable way are associated with different peer group effects. While online peer groups in our study provided better outcomes in the integration domain
rights and citizenship, which relates to the peer group effect
positive behaviour change (e.g., Klier et al.
2019), they showed weaker outcomes in the integration domains
social bonds and
safety and stability which relates to the peer group effects
intensification of social connectedness (e.g., Goswami et al.
2010) and
increase of general well-being (e.g., Prevatt et al.
2018), respectively. Both online and offline peer groups showed positive outcomes in the domain
social bridges. To the best of our knowledge, we are the first to quantitatively demonstrate differences in effectiveness between the two foundational realizations of peer groups: online and offline. We thereby extend understanding of ICT impacts by contributing to the so far unanswered research question of the relative importance of online characteristics in peer groups (Klier et al.
2019). In our study, the following differences were apparent between the two realizations: Only online peer groups stayed stable in the construct
attachment to host country, whereas offline peer groups showed a highly significant, undesired decrease in that measure (
p < 0.01). In contrast, there was no significant development in online peer groups with respect to
frequency of contact with people of home culture and
overall life satisfaction, whereas offline peer groups significantly increased in both variables as desired (
p < 0.05;
p < 0.1). Literature on online characteristics and participants’ feedback provides avenues to interpret these differences. Online peer groups are characterized by non-copresence (Coulson
2013). While offline peer groups increased contact with people from their home country, partly by broadening the connection with other refugees in the offline meetings, online peer groups provided support without intensifying contacts amongst each other beyond the participation in the virtual channel. Since online peer group participants only met virtually, they did not strengthen and broaden their network with other refugees, thus, this intervention did not result in increasing their contact to people from their home country. In turn, we conclude that the lower occurrence of a community feeling in the online peer groups allows participants to also feel attached to other people, indicating superior effects with respect to
attachment to host country. Participants in the offline peer groups reported a different experience with the peer group intervention. They stressed the personal exchange among peers and an atmosphere comparable to a “teahouse”, resulting in a feeling of closeness to peers in offline peer groups in line with literature (Sannomiya and Kawaguchi
1999). Accordingly, prior research suggests that while in online peer groups information plays a more central role, in offline peer groups emotional support and helper therapy are more relevant (Setoyama et al.
2011; Bender et al.
2013). This stronger feeling of connectedness to peers and more central role of helper therapy might explain superior effects of offline peer groups with respect to
frequency of contact with people of home culture and
overall life satisfaction.
Through this comparison of online and offline peer groups, we furthermore extend insights into the impact of ICT in the specific context of the study, i.e., refugee integration. Prior studies in this context emphasize the value of ICT with respect to
social bridges and
social bonds (e.g., Lloyd and Wilkinson
2017; AbuJarour et al.
2018; Alencar
2018; Kutscher and Kreß
2018). First, while AbuJarour et al. (
2018) found that ICT helps resettled refugees to communicate with their friends and family back home and thereby increase their sense of social connectedness, our study suggests that connecting resettled refugees face-to-face is more effective for increasing
social bonds than connecting them via ICT. Furthermore, existing research proposes that refugees’ online communication with people from the host culture is positively correlated with a sense of social connectedness with people from the host culture (AbuJarour et al.
2018). The results of our study expand these findings and suggest that even online communication among refugees themselves can increase
social bridges. Thus, online peer groups, although ‘only’ connecting refugees with other refugees, might answer the call for ICT connecting people from the host culture and the home culture (AbuJarour et al.
2019). Finally, prior research found that refugees use ICT to consume and produce cultural content which helps them to maintain a continued connection to their home country (Díaz Andrade and Doolin
2019). In contrast, the online peer groups in our study prove effective for maintaining the
attachment to the host country: While participation in online peer groups did not increase the
attachment to their home country, participants in these groups did not experience the decrease of the
attachment to the host country of the offline peer groups and control group.
Third, our results provide evidence that online peer groups are used to a higher extent than offline peer groups in the context of refugee integration. We find that a significantly higher percentage of participants of the online peer groups (50.8%) used the approach on a regular basis than participants of the offline peer groups (11.1%). While prior research proposes advantages of online peer groups compared to offline peer groups due to time- and location-independent accessibility (Coulson
2013), our study empirically shows that ICT fosters participation in peer groups via a randomized field experiment. In our study, participants reported distance, domestic responsibilities and attending other interventions as main reasons to not make use of the offline peer groups.
Along these theoretical insights, our findings indicate four practical implications to guide decisions in public sector and non-profit organizations.
First, our study demonstrates that peer groups are an effective instrument to enhance refugee integration in four of five dimensions of integration. They particularly help to improve integration by increasing refugees’ social connectedness with people from the home and host country and stabilizing their attachment to the home and host country. Against the background that the latest integration summit in Germany (March 2021) reported mixed results with respect to integration interventions for refugee and migrant integration in Germany over the last 15 years, peer groups represent a highly promising approach for refugee integration.
Second, our results show that there is no one-size-fits-all approach to enhance refugee integration, but rather online and offline peer groups are particularly effective in distinct integration domains. Depending on the specific target of integration, the online or offline realization might thus be more advantageous for public sector organizations and non-profit organizations. Being aware of the differences in effectiveness of the two realizations helps organizations to allocate resources more effectively and efficiently.
Third, in the age of digitalisation, the online realization bears advantages for public sector and non-profit organizations. In particular, the online realization of the peer-group-based approach is more promising for implementation on a larger scale. Indeed, our findings regarding the usage of the two realizations suggest that the online realization provides a low-threshold access for participation via smartphone to the peer group as, on average, online peer groups are used more frequently than offline peer groups. At times of crises like Covid-19, online services often remain the only feasible option. The specific insights into online peer group benefits and effects are becoming more relevant as they support stakeholders of public or social services in quickly and reasonably introducing effective digital services whenever necessary.
Finally, organisations that intend to implement a peer-group-based approach to enhance refugee integration should be aware that online peer groups as a digital service demand different working models and competencies than offline peer groups. To illustrate this, moderators of offline peer groups need to host regular in-person meetings (for instance weekly one-hour meetings as in our study), while moderators of online peer groups can flexibly (in time and location) participate in discussions during working hours. This showcases that digitalisation and digital services go along with different requirements for associated organizations.
6.2 Limitations and Future Research
Aside from the highlighted research contribution presented in this paper, our approach is also subject to limitations which can serve as promising starting points for further research. First, the strengths of our study notwithstanding, our findings are limited regarding the number of participants. Although we could already show significant results for the (separately observed) developments of the two treatment groups and the control group in our study, future research with a larger pool of participants would allow to use more advanced methods to strengthen our results, increase their generality and generate more nuanced insights. For example, methods like differences-in-differences estimators or regression analyses could be used to test for statistical differences between the experimental groups in terms of their development over time. Further, a larger sample would allow for more differentiated insights, e.g., which types of participants extract greater benefit from the online or offline peer groups. Second, the limited observation period of three months did not allow us to analyse long-term effects of our treatments. While we could measure significant developments in domains of integration like
social bonds and
social bridges describing refugees’ social connectedness, we for instance only found a mitigating effect in
attachment to host country for online peer groups and could not investigate all integration domains proposed by Ager and Strang (
2008). Still, our research provides a promising starting point for future studies investigating long-term effects of online peer groups for refugee integration. Third, despite the valuable opportunity to conduct a field experiment, the generalizability of our findings might be limited by the fact that we conducted our study in one single setting at one “Integration Point”. Even though Germany hosts the largest absolute number of refugees among EU countries in mid-2020 (UNHCR
2020b), we invite future research to evaluate our peer-group-based approach in other geographical or cultural settings, as studies on ICT in the context of refugee integration are “a context-specific phenomenon” (AbuJarour et al.
2019, p.15). Fourth, in our study, we focused on refugees with basic skills in the home country’s language along with a certain duration of stay to maximize the impact of the (online) peer-group-based approach. However, future studies could design variants of this artefact, which allow also new arrivals to participate and benefit from it, and analyse effects on refugee integration for this target group as well. Fifth, even though our artefact primarily focuses on the refugee perspective of the two-way integration process (cf. e.g., Da Lomba
2010; Alencar and Tsagkroni
2019) both in the design and the evaluation of the artefact, professional counsellors from public (refugee) services and social workers from non-governmental organization take part in the approach as moderators and experts. Through participating in the (online) peer groups, those stakeholders potentially learn from the refugees as well. Consequently, there might be positive effects on the host community through the artefact which could be explored in future research. Sixth, our data collection is based on measurement of constructs’ initial level and final level to determine the subjects’ development in our study. Future research might deepen these insights by observing the continuous development throughout the treatment period, for instance regarding the domain
safety and stability that may also be subject to more short-term fluctuations. Finally, although we considered two realizations of peer groups for refugees, future studies could conduct another cycle in the iterative design science process (Hevner et al.
2004) and consider further realizations of our artefact, like for example hybrid solutions.
