Abstract

This study aimed to develop a causal model of factors influencing the organizational commitment of nursing instructors under Praboromarajchanok Institute, Ministry of Public Health and study guidelines for building organizational commitment. The research was conducted in three phases: 1) developing the causal model through a literature review and interviewed 15 experts and nursing instructors; 2) validating the model and analyzing the effects of influencing factors based on data collected from 586 nursing instructors across 30 institutions; 3) developing guidelines for enhancing organizational commitment through a connoisseurship seminar with 8 experts. The research instruments included structured interviews and validated questionnaires, seminar questions, and an evaluation form for a draft of guidelines for enhancing organizational commitment. Data analysis was conducted using structural equation modeling (SEM) and framework analysis for qualitative data.


The results showed that: 1) the causal model included one external latent variable: transformational leadership and four internal latent variables: perceived organizational justice, perceived organizational support, job satisfaction, and organizational commitment; 2) the model was consistent with empirical data (ð‘ĨÂē = 82.115, df = 64, p = 0.063, CFI = 0.998, TLI = 0.995, RMSEA = 0.022, SRMR = 0.027); 3) the factors with the highest total effect on organizational commitment were job satisfaction (=1.414), followed by perceived organizational justice (=1.149) and transformational leadership (=0.528). Guidelines for fostering organizational commitment encompassed four areas: improving job satisfaction, developing transformational leadership among administrators, promoting organizational justice, and enhancing organizational support among nursing instructors.
