The relationship between instrumental motivation and English communication behavior through learning perseverance and self efficacy among Vietnamese undergraduates

This mixed-methods study of Vietnamese undergraduates reveals that instrumental motivation influences English communication behavior indirectly through a sequential pathway where career-oriented goals first foster learning perseverance, which in turn strengthens English self-efficacy to drive actual communicative engagement.

The Big Picture: The "Career Ladder" vs. The "Actual Climb"

Imagine you are standing at the bottom of a very tall, slippery ladder. Your goal is to reach the top, where a big sign says "High-Paying Job." This desire to get the job is what the researchers call Instrumental Motivation.

The study asked a simple question: Does just wanting the job at the top automatically make you climb the ladder?

The answer, according to this study of 382 Vietnamese university students, is no. Just having the goal isn't enough to get you moving. Instead, the desire for the job has to go through two specific "checkpoints" before it turns into actual action (speaking English).

The researchers found a specific chain reaction:
The Goal (Motivation) → The Grind (Perseverance) → The Confidence (Self-Efficacy) → The Action (Speaking).

Here is how that chain works, step-by-step.

Step 1: The Spark (Instrumental Motivation)

The Paper's Claim: Students want to learn English because they need it for their careers.
The Analogy: Think of this as the ignition key in a car. Turning the key (wanting the job) is necessary to start the engine, but it doesn't actually make the car move down the road yet. It's just the reason you are in the car.

Step 2: The Engine Work (Learning Perseverance)

The Paper's Claim: The desire for a career must first turn into sustained effort. Students have to keep studying and practicing even when English is hard (like confusing grammar or tricky pronunciation).
The Analogy: This is the gas pedal. You can't just turn the key and float; you have to press down and keep pressing. The study found that students who wanted the job did press the pedal harder, but this effort is a separate step from just having the desire. It's the "grit" of keeping going when the road gets bumpy.

Step 3: The Dashboard Light (English Self-Efficacy)

The Paper's Claim: When students keep pressing the gas (persevering), they start to feel like they are actually getting somewhere. This builds confidence. They start to believe, "I can do this."
The Analogy: This is the dashboard light that says "Engine Running Smoothly." You don't feel confident just because you want to drive; you feel confident because you've been driving for a while and the car hasn't stalled. The study shows that this feeling of "I can do it" is the most direct thing that makes you actually speak up.

Step 4: The Movement (English Communication Behavior)

The Paper's Claim: This is the final result: actually speaking English in real life, in class, or with friends.
The Analogy: This is the car actually moving forward. The study found that the car doesn't move just because you turned the key (Motivation). It moves because you pressed the gas (Perseverance), which made the engine run smoothly (Confidence), which finally allowed the wheels to turn (Speaking).

The "Secret Sauce" of the Study

The researchers used a mix of math (surveying 382 students) and storytelling (interviewing 30 students) to prove this chain.

What the Math Said:
They built a complex map (a statistical model) and found that the path from "Wanting a Job" to "Speaking English" is a relay race, not a straight line.

Wanting a Job passes the baton to Hard Work.
Hard Work passes the baton to Confidence.
Confidence crosses the finish line with Speaking.

Interestingly, the math showed that "Wanting a Job" has a very weak direct connection to "Speaking." It's like trying to push a heavy boulder with just your pinky finger. But if you use your whole body (Hard Work) to build momentum, and then your muscles get strong (Confidence), then the boulder moves easily.

What the Stories Said:
When the researchers talked to the students, the students confirmed this.

One student said, "I know I need English for my career, but I'm scared to speak."
Another said, "I keep trying even when I make mistakes, and that makes me feel brave enough to talk."
A third said, "Once I felt I was getting good at it, I stopped worrying and just started talking."

The Main Takeaway

If you are a teacher, a parent, or a student, the lesson is this: You cannot force someone to speak English just by telling them it will get them a job.

The desire for the job is the starting line, but it's not the finish line. To get students to actually speak, you have to help them:

Keep trying when things get hard (Perseverance).
Feel good about their progress (Confidence).

Once those two things happen, the speaking happens naturally. The study proves that the "grind" and the "belief" are the invisible bridges that connect a career goal to real-world conversation.

Technical Summary: Instrumental Motivation, Learning Perseverance, Self-Efficacy, and English Communication Behavior

Problem Statement and Research Gap
The study addresses a critical gap in Second Language Acquisition (SLA) literature regarding the mechanism through which instrumental motivation (IM)—defined as career-driven, utilitarian orientation—translates into actual English communication behavior (ECB). While traditional frameworks acknowledge IM as a predictor of language achievement, empirical evidence suggests that extrinsic goals alone are insufficient to sustain active oral interaction, particularly when learners face linguistic complexities and evaluative anxieties. The specific problem investigated is the lack of clarity on the indirect, sequential pathways that convert distal vocational aspirations into proximal communicative actions within the Vietnamese higher education context. The study posits that the relationship between IM and ECB is not direct but is serially mediated by behavioral investment (Learning Perseverance, LP) and cognitive self-belief (English Self-Efficacy, ESE).

Methodology
The research employed an explanatory sequential mixed-methods design involving two distinct phases:

Quantitative Phase: A cross-sectional survey was administered to 382 undergraduate English majors from public universities in Vietnam. The sample included students across all four academic years, with a majority at upper-intermediate (B2/C1) or intermediate (B1) proficiency levels. Data were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM) via SmartPLS 4. This variance-based approach was selected to model multi-stage sequential mediation without strict assumptions of multivariate normality. The analysis included assessments of measurement model reliability (Cronbach's alpha, Composite Reliability), validity (AVE, HTMT ratios), and structural path coefficients, utilizing bootstrapping (5,000 resamples) to test significance.
Qualitative Phase: Semi-structured interviews were conducted with a purposive sub-sample of 30 participants representing varying levels of perseverance and self-efficacy. Thematic analysis (following Braun & Clarke, 2021) was used to explore the socio-psychological factors underlying the quantitative patterns, specifically examining how career goals interact with linguistic challenges and self-perception.

Key Results
The structural model demonstrated robust explanatory power, accounting for 58.9% of the variance in English communication behavior (ECB). The empirical diagnostics yielded the following key findings:

Direct Effects: Instrumental motivation (IM) significantly predicted Learning Perseverance (LP), English Self-Efficacy (ESE), and ECB directly. However, the effect size of IM on ECB was small ( $f^2 = 0.092$ ), suggesting that career goals alone have limited capacity to drive communication without mediation. Conversely, ESE emerged as a substantial proximal driver of ECB ( $f^2 = 0.284$ ).
Mediation Pathways: All hypothesized single mediation paths were supported:
- IM $\rightarrow$ ESE $\rightarrow$ ECB
- IM $\rightarrow$ LP $\rightarrow$ ECB
- LP $\rightarrow$ ESE $\rightarrow$ ECB
Sequential Mediation (H11): The study validated the primary hypothesis of a sequential trajectory: IM $\rightarrow$ LP $\rightarrow$ ESE $\rightarrow$ ECB. This path was statistically significant ( $\beta = 0.062, p < 0.001$ ), confirming that instrumental motivation influences communication behavior indirectly by first fostering sustained behavioral effort (LP), which in turn accumulates mastery experiences to reinforce self-efficacy (ESE), ultimately triggering communicative execution.
Qualitative Corroboration: Thematic analysis revealed that while professional aspirations act as a catalyst for seeking practice, students require "cognitive persistence" to navigate linguistic complexity. Participants indicated that sustained effort mitigates anxiety and stabilizes self-belief, allowing them to view communication as a skill-building process rather than an evaluative performance.

Key Contributions

Theoretical Integration: The study integrates Social Cognitive Theory with behavioral frameworks to propose a unified, serialized socio-psychological model. It moves beyond viewing motivation and self-efficacy as isolated predictors, demonstrating that behavioral perseverance is the necessary engine that converts extrinsic goals into cognitive competence beliefs.
Distinction between Intention and Behavior: By operationalizing ECB as the actualized frequency of speech acts rather than the internal "Willingness to Communicate" (WTC), the research bridges the gap between psychological readiness and observable linguistic performance.
Contextual Specificity: The findings provide empirical evidence specific to Vietnamese English majors, a demographic where vocational demands are high but communicative practice may be hindered by anxiety, offering a nuanced view of how career goals function in this specific EFL environment.

Significance and Claims
The paper claims that instrumental motivation is a necessary but insufficient antecedent for proactive communicative engagement. Its significance lies in demonstrating that the translation of vocational aspirations into actualized linguistic engagement requires a "serialized psychological transition." Specifically, career goals must first be internalized as sustained behavioral effort (grit), which then builds the cognitive self-belief (self-efficacy) required to regulate communication behavior.

The authors conclude that pedagogical interventions focusing solely on highlighting the economic value of English are inadequate. Instead, effective strategies must foster "behavioral grit" and mitigate evaluative pressures to help students align their professional aspirations with the persistent effort and self-confidence necessary for actualized communication. The study cautions that these findings are context-specific to Vietnamese English majors and cross-sectional in nature, limiting causal inferences and generalizability to other disciplines or cultures without further validation.
