Abstract

Penggunaan rokok elektronik (vape) pada kelompok emerging adults terus mengalami peningkatan dan menjadi perhatian karena berpotensi menimbulkan ketergantungan nikotin serta berbagai dampak kesehatan. Meskipun sebagian besar pengguna menyadari manfaat berhenti menggunakan vape, tidak semua memiliki intensi yang kuat untuk menghentikan perilaku tersebut. Penelitian ini bertujuan untuk menganalisis pengaruh Attitude, Subjective Norm, Perceived Behavioral Control, dan Craving Behavior terhadap Intensi Berhenti Menggunakan Vape pada emerging adultsberdasarkan kerangka Extended Theory of Planned Behavior. Penelitian ini menggunakan pendekatan kuantitatif dengan desain eksplanatif. Responden penelitian berjumlah 305 emerging adults berusia 18–29 tahun yang aktif menggunakan vape dan dipilih menggunakan teknik purposive sampling. Data dikumpulkan menggunakan kuesioner yang dikembangkan melalui elicitation study sesuai pedoman Ajzen (2006), sedangkan variabel Craving Behaviordiukur menggunakan adaptasi Tobacco Craving Questionnaire–Short Form (TCQ-SF). Analisis data dilakukan menggunakan Hierarchical Multiple Regression dengan bantuan perangkat lunak JASP. Hasil penelitian menunjukkan bahwa Model 1, yang terdiri atas Attitude, Subjective Norm, dan Perceived Behavioral Control, mampu menjelaskan 57,7% variasi Intensi Berhenti Menggunakan Vape (R² = 0,577). Setelah variabel Craving Behavior ditambahkan pada Model 2, kemampuan model meningkat menjadi 57,8% (R² = 0,578) dengan kontribusi tambahan sebesar 0,1% (ΔR² = 0,001), namun peningkatan tersebut tidak signifikan secara statistik. Secara parsial, hanya Subjective Norm yang berpengaruh positif dan signifikan terhadap Intensi Berhenti Menggunakan Vape, sedangkan Attitude, Perceived Behavioral Control, dan Craving Behavior tidak menunjukkan pengaruh yang signifikan. Temuan ini menunjukkan bahwa pembentukan intensi berhenti menggunakan vape pada emerging adults lebih dipengaruhi oleh faktor sosial dibandingkan faktor individual. Penelitian ini mendukung penerapan Theory of Planned Behavior dalam menjelaskan intensi berhenti menggunakan vape serta menunjukkan bahwa penambahan Craving Behavior memberikan kontribusi tambahan yang relatif kecil terhadap kemampuan prediksi model. *** The use of electronic cigarettes (vaping) among emerging adults has continued to increase and has become a public health concern due to its potential to cause nicotine dependence and various adverse health effects. Although many users recognize the benefits of quitting vaping, not all develop a strong intention to stop. This study aimed to examine the effects of Attitude, Subjective Norm, Perceived Behavioral Control, and Craving Behavior on the Intention to Quit Vaping among emerging adults based on the Extended Theory of Planned Behavior. This study employed a quantitative explanatory design. The participants consisted of 305 emerging adults aged 18–29 years who were active vape users and were selected using purposive sampling. Data were collected using a questionnaire developed through an elicitation study based on Ajzen's (2006) guidelines, while Craving Behavior was measured using an adapted version of the Tobacco Craving Questionnaire–Short Form (TCQ-SF). Data were analyzed using Hierarchical Multiple Regression with JASP software. The results indicated that Model 1, consisting of Attitude, Subjective Norm, and Perceived Behavioral Control, explained 57.7% of the variance in the Intention to Quit Vaping (R² = 0.577). After Craving Behavior was added in Model 2, the explanatory power increased slightly to 57.8% (R² = 0.578), representing an additional contribution of 0.1% (ΔR² = 0.001); however, this increase was not statistically significant. Partial regression analysis revealed that only Subjective Norm had a positive and significant effect on the Intention to Quit Vaping, whereas Attitude, Perceived Behavioral Control, and Craving Behavior did not show significant effects. These findings suggest that the intention to quit vaping among emerging adults is influenced more strongly by social factors than by individual factors. This study supports the applicability of the Theory of Planned Behavior in explaining the intention to quit vaping and demonstrates that adding Craving Behavior provides only a minimal additional contribution to the model's predictive ability.
