Participants in the experimental group received the four-session Mindful Caring Education Program. Subsequently, a mobile application named M-MindCare was installed, and participants were asked to use it for three months.

No intervention was administered to the nurses in the control group during the study, and they continued their routine work processes.

The Self-Care Activities Screening Scale (SASS) was used to assess participants' self-care behaviors. The scale consists of 14 items, each rated on a 6-point Likert scale ranging from 1 to 6. The total score ranges from 14 to 84. Higher total scores indicate greater engagement in self-care behaviors.

The Self-Compassion Scale (SCS) was used to assess participants' levels of self-compassion. The scale consists of 26 items rated on a 5-point Likert scale. Each sub-dimension is scored separately, and the total self-compassion mean score is obtained. The total score is calculated by summing the scale items and dividing the result by 26. A total score between 1 and 2.49 indicates low self-compassion, a score between 2.5 and 3.5 indicates moderate self-compassion, and a score between 3.51 and 5 indicates high self-compassion. Higher total scores indicate higher levels of self-compassion.

The Professional Quality of Life Scale (ProQOL) was used to assess participants' professional quality of life. The scale consists of 30 items and comprises three subscales: Compassion Satisfaction, Burnout, and Compassion Fatigue. The scale does not yield a total score. Instead, each subscale is scored and interpreted independently. During scoring, items 1, 4, 15, 17, and 29 are reverse scored.

The Caring Nurse-Patient Interaction Scale-Short Form (CNPI-Short Scale) was used. The scale consists of 23 items. Each item is evaluated across three dimensions: importance, competence, and feasibility. The scale does not yield a total score; instead, each dimension is scored and interpreted independently. Each item is evaluated using a five-point Likert-type scale with separate instructions appropriate to the target dimension. Scores on the scale range from 23 to 115. Higher scores indicate a more positive perception of the measured dimension and subdimension.
