Question: Effectiveness was evaluated through pre-post-measurements of state anxiety (STAI-X1), affect (PANAS), and visual analogue scales for stress, relaxation, and well-being. VR demonstrated strong feasibility, with low dropout rates, high satisfaction and immersion, and minimal motion sickness (M = 0.25 ± 0.91). Mixed repeated measures ANOVA analyses revealed significant improvements in state anxiety, stress, negative affect, relaxation, positive affect, and well-being across both groups (p < 0.001), with no significant differences between VR and GI. Feasibility and effectiveness were consistent across age, gender and severity of illness. Our findings suggest that VR relaxation is a feasible and effective intervention for older adults with mental illness, offering a comparable alternative to traditional relaxation methods. This study underscores the potential of VR to enhance mental health care for older populations, including those with advanced age and serious mental illness. Need Assignment Help?
