Abstract: The complex interplay between stress levels, self-efficacy, and emotional intelligence (EI) has a profound impact on the overall well-being and operational effectiveness of military personnel. This study centers on the implementation of a targeted intervention model developed by the researchers, aimed at alleviating stress while simultaneously enhancing self-efficacy and emotional intelligence among army personnel. Using a pre-test/posttest experimental design, the researchers selected 150 army members in Pune, India, divided into two age groups: 25–35 years and 36–45 years, with 75 participants each. Over eight weeks, the intervention included 24 sessions featuring positive behavior therapy, muscle relaxation therapy, breathing, yoga, meditation, and counseling, all aimed at improving participants’ psychological resilience. Results indicated that the combination of cognitive-behavioral methods and mindfulness techniques effectively reduced stress and improved self-efficacy and EI. However, the research has limitations, as it focused solely on military personnel, which may restrict the relevance of findings to civilian populations. Additionally, the concentrated approach may have missed other important psychological factors affecting participants’ overall well-being.
