This RCT study provides important results to the application of workplace mental health
programs for nurses in low- and middle-income country. Healthcare workers, including
nurses in LMIC are at high risk of work-related mental disorders which have detrimental
impacts on their health and quality of health services they provide. Meanwhile, low cost
technology based mental health programs with easy access have showed effectiveness on
improvement of workers’ mental health in high-income countries. This RCT study aimed
to investigate the effect of newly adapted smartphone based mental health programs on
depression and anxiety among nurses in Vietnam, and the following results have been
obtained.
1. Both programs (a fixed-order, internet cognitive behavioral therapy (iCBT)
program B and a multimodule stress management techniques program A with a
free-choice sequence) showed nonsignificant effectiveness on improvement of
anxiety and depression among nurses at the end of the study.
2. Program B significantly improved nurses’ depressive symptoms at three-month
(p=0.048; Cohen’s d: -0.18, 95% Confident interval: -0.34 to -0.02), but not at
seven-month (p=0.92). Program A showed a nonsignificant effect on depression.
Both intervention programs were not efficacious in anxiety improvement at any
follow-up.
3. The iCBT program B is a potential, low cost stress management intervention to
improve depression for hospital nurses in Vietnam.

As described above, this study provides new insights on mental health intervention for
nurses, an indispensable workforce of the health system in Vietnam. This is the first RCT
to show the effectiveness and feasibility of a smartphone-based CBT intervention to
improve depression among nurses in a LMIC
