Validating and Extending the L2 Willingness to Communicate Scale: Incorporating Virtual Exchange Contexts

Technical Summary: Validating and Extending the L2 Willingness to Communicate Scale

Problem Statement
While the concept of Willingness to Communicate (WTC) in a second language (L2) is well-established, existing measurement instruments fail to adequately capture the nuances of structured, institutionally guided digital interactions known as Virtual Exchange (VE). Current scales, such as the L2 WTC-R (Lee & Drajati, 2019), successfully differentiate between classroom, outside-classroom, and Informal Digital Learning of English (IDLE) contexts. However, IDLE items primarily reflect self-directed, low-stakes, and often asynchronous communication. They do not account for the unique psychological parameters of VE, which are characterized by structured, synchronous, task-based, and often evaluated interactions (e.g., Collaborative Online International Learning). Consequently, there is a measurement gap regarding how learners conceptualize these formal digital exchanges and whether they constitute a distinct communicative domain or integrate into existing WTC constructs. Additionally, the influence of interlocutor background (native vs. non-native speakers) within these specific digital contexts remains under-explored in validated instruments.

Methodology
This study employed a quantitative, cross-sectional design to validate and extend the L2 WTC-R scale within a Japanese EFL context.

• Participants: Data were collected from two independent samples of first-year undergraduate students at a university in Kumamoto, Japan, with an estimated CEFR A2 proficiency level. Sample 1 (N = 195) was used for Exploratory Factor Analysis (EFA), and Sample 2 (N = 351) was used for Confirmatory Factor Analysis (CFA).
• Instrument: The researchers developed the L2 WTC-VE scale, a 14-item instrument. This was derived from the original 11-item L2 WTC-R scale by:
  1. Reintroducing one previously excluded item (WTC OC-3).
  2. Adding two new items specifically designed to capture synchronous, real-time VE interactions via smartphones or computers, explicitly distinguishing between communication with native and non-native speakers.
  3. Adapting wording for clarity and cultural relevance for Japanese learners.
• Procedure: The instrument was translated and back-translated by bilingual experts. Participants rated items on a 5-point Likert scale ranging from "Definitely not willing" to "Definitely willing."
• Analysis: Data analysis was conducted using JASP software.
  • EFA: Principal axis factoring with oblimin rotation was applied to Sample 1 to examine the factor structure of the 14 items.
  • CFA: Maximum likelihood estimation was applied to Sample 2 to validate the structural validity and reliability of the model, utilizing standard fit indices (χ²/df, CFI, GFI, RMSEA, SRMR).
  • Comparative Analysis: Paired-samples t-tests were conducted to compare mean scores for items specifying native versus non-native interlocutors within VE and IDLE contexts.

Key Results

• Factor Structure: The EFA and CFA results supported a robust three-factor structure consistent with the original L2 WTC-R framework: Willingness to Communicate Inside the Classroom (WTC IC), Outside the Classroom (WTC OC), and in IDLE contexts (WTC IDLE).
• Integration of VE Items: Contrary to the hypothesis that VE might form a distinct fourth factor, the two new VE items loaded strongly onto the "Inside the Classroom" (WTC IC) factor. This indicates that Japanese EFL learners conceptualize structured virtual exchanges as formal academic tasks rather than informal digital activities.
• Reliability and Validity: The 14-item scale demonstrated high internal consistency and construct validity. Cronbach's alpha values were .892 (WTC IC), .867 (WTC IDLE), and .842 (WTC OC). CFA fit indices for the 14-item model met recommended thresholds (CFI = .946, RMSEA = .078, SRMR = .050), confirming the model's stability.
• Interlocutor Effects: A comparative analysis revealed a small but statistically significant preference for communicating with non-native speakers in VE contexts (spoken, synchronous video interaction), where learners reported higher willingness with non-native interlocutors. Conversely, no significant difference was observed in IDLE contexts (asynchronous, text-based social media), where willingness levels were similar regardless of interlocutor background.

Significance and Claims
The paper claims to make three primary contributions to the field of applied linguistics and L2 acquisition:

1. Empirical Validation: It provides empirical support for the applicability of the L2 WTC-R scale structure among Japanese university learners, reinforcing its cross-contextual validity.
2. Instrument Extension: It successfully extends the measurement framework by incorporating VE-specific scenarios, resulting in the L2 WTC-VE scale. This tool allows researchers and practitioners to assess communicative readiness in structured digital environments without disrupting the established theoretical model.
3. Contextual Nuance: The findings highlight the critical role of communication mode (synchronous vs. asynchronous) and perceived evaluative pressure in shaping WTC. The study suggests that learners distinguish between digital interactions not only by formality but also by interactional conditions; specifically, the anxiety associated with native-speaker interactions appears more pronounced in synchronous, spoken VE contexts than in asynchronous IDLE contexts.

The authors conclude that the L2 WTC-VE scale serves as a practical diagnostic tool for assessing learners' readiness to participate in contemporary, digitally mediated language learning settings, particularly those involving structured virtual exchanges. They note limitations regarding the cross-sectional nature of the data and the specific institutional context, suggesting that future research should examine longitudinal changes in WTC and measurement invariance across diverse populations.
