The effect of mobile health application training based on micro-learning method on the level of resilience and happiness among intensive care nurses: a randomized controlled trial

Increasing the level of resilience and happiness of intensive care nurses can lead to an improvement in their psychological health. This study aimed to extract the possible effectiveness of mHealth application utilizing the micro-learning method on a mobile phone platform on the intensive care nurses’ resilience and happiness.

This single-blind randomized controlled trial was conducted in 2022-24. Sixty nurses working in intensive care units at two hospitals in Tehran, Iran were recruited using purposive sampling and randomly assigned to either the intervention or control group. Techniques of resilience and increasing happiness were taught to the intervention group using the mHealth application based on the micro-learning method. No training was provided to the control group. For data collection, questionnaires of individual characteristics, Connor-Davidson Resilience, and Oxford Happiness were used.

Before the intervention, there was no significant difference between the mean of the subscales and the total score of resilience and happiness of the intervention and control groups (P < 0.05). However, after the intervention, there was a significant difference (P < 0.05). After using the mHealth application, the total resilience score of the intervention group increased from 67.30 ± 10.12 to 79.27 ± 5.87 (P < 0.0001), while the resilience of the control group changed from 68.80 ± 9.09 to 65.93 ± 8.44 (P = 0.548). Similarly, using the mHealth educational application based on micro-learning led to an increase in the happiness score of the intervention group from 38.50 ± 11.10 to 67.83 ± 8.84 (P < 0.0001), whereas the happiness score of the control group nurses after the intervention (38.93 ± 14.33) compared to the baseline (41.40 ± 14.51) did not change significantly (P = 0.388).

The use of the mHealth application based on the micro-learning method played an effective role in training resilience and happiness skills in nurses. It is recommended to conduct more studies using this new educational approach.

The study has been registered in the Iranian Registry of Clinical Trials (No. IRCT20221225056916N1, Date: 04/29/2023).
