Mobile micro-learning intervention contains a 10-minute video about cardiopulmonary resuscitation to continuously improve their self-confidence, motivation and reduce their stress

It contains 12 items on a 5-point Likert scale (1 = not confident; 2 = hardly confident; 3 = confident; 4 = very confident; and 5 = extremely confident), with scores ranging between 12 and 60, with higher scores indicating more confidence.

This instrument examined eight dimensions, including facilitators of resuscitation (6 items), feeling of achievement (7 items), high chances of success (8 items), low chances of success (6 items), recognition and appreciation (6 items), accountability (4 items), perceived importance (3 items), and beliefs (3 items). The scale of the questionnaire was a five-point Likert scale. More specifically, the first three items were rated on a scale ranging from always to never (i.e. 5 = always, 4 = most of the time,3 = sometimes,2 = rarely, and 1 = never). Moreover, the remaining items were rated on a scale ranging from completely agree to 'neither agree nor disagree (i.e. 5 = I completely agree score, 4 = I agree, 3 = I disagree, 2 = I completely disagree, and 1 = neither agree nor disagree).

It consist of 20 items, the 5-level Likert scale, where: 1-the claim does not apply to me, 2-the claim hardly applies to me, 3-I cannot decide whether the claim applies to me or not, 4-the claim often applies to me and 5-the claim is typical of me
