Penelitian ini dilakukan pada mahasiswa dari Fakultas Ekonomi di Universitas Methodist Indonesia di Medan yang telah membeli dan menggunakan smartphone Samsung. Penelitian ini bersifat kuantitatif dengan pendekatan asosiatif. Ukuran sampel untuk penelitian ini adalah 89 responden, diambil dengan menggunakan teknik purposive sampling. Pengumpulan data dilakukan melalui kuesioner. Teknik analisis data yang digunakan adalah analisis regresi linier berganda, uji-t, uji-F, dan koefisien determinasi (R²) dengan menggunakan SPSS versi terbaru. Hasil penelitian menunjukkan bahwa secara parsial, variabel E-WOM, Kualitas Informasi, Kualitas yang Dirasakan, dan Citra Merek berpengaruh positif dan signifikan terhadap Keputusan Pembelian. Secara simultan, keempat variabel ini juga berpengaruh positif dan signifikan terhadap Keputusan Pembelian. Koefisien determinasi (R²) sebesar 0,844 menunjukkan bahwa 84,4% keputusan pembelian dipengaruhi oleh keempat variabel tersebut, sedangkan sisanya sebesar 15,6% dipengaruhi oleh variabel di luar model penelitian ini

Abstract

This research investigates how Mental Health Support System (MHSS) implementation functions as a comprehensive intervention mechanism for enhancing organizational performance through improved employee well-being in large hospitals in Medan. Drawing upon Job Demands-Resources (JD-R) theory, Conservation of Resources (COR) theory, and organizational support theory, this study examines how mental health support systems create value through improved employee psychological well-being and reduced work-related stress among healthcare workers. Using Structural Equation Modeling with Partial Least Squares (PLS-SEM) analysis on 8 large hospitals in Medan (385 healthcare worker observations, 2023-2024), the research demonstrates that mental health support system implementation significantly enhances employee well-being (β = 0.692, p < 0.001) and directly improves organizational performance (β = 0.458, p < 0.001). Employee well-being substantially mediates the relationship between mental health support systems and organizational performance (indirect effect = 0.389, p < 0.001, VAF = 45.9%). The model explains 61.8% of employee well-being variance and 68.3% of organizational performance variance. This study provides comprehensive empirical evidence of how mental health support systems transform healthcare workplace environments and operational effectiveness in hospital settings
