The population of the study consisted of 123 students who were first-year students in the Home Patient Care Program. Control group (n=29)

The hand washing skills of the students in the three groups were evaluated by a researcher by observing the hand washing of the students in the sink with the Hand Washing Skills Checklist. After the students were given theoretical information about hand hygiene, including the importance of hand washing, the situations in which hands should be washed, and the steps of hand washing skills, the laboratory practice was started immediately afterwards. In the laboratory, hand washing training was given to the video group with the hand washing video developed by the researchers within the scope of the course. Afterwards, the same researcher who made the first observation re-evaluated the handwashing skills of all students in the sink by filling out the Handwashing Skill Checklist.

It was developed by the researchers and includes seven questions including age, gender, family type, economic status, previous hand hygiene training, need for hand hygiene training, and hand washing frequency.

The checklist prepared by the researchers in line with the WHO (World Health Organization) guidelines consists of 20 steps to evaluate the hand washing skills of the students. For the developed checklist, expert opinion was obtained from 5 Fundamentals of Nursing experts. Among the steps in the checklist, 0 points were given to the steps that were not applied, 0.5 points to the missing applied steps, and 1 point to the correctly applied steps. The highest score that students can get from the hand washing skill checklist is 20 points.

It was developed by Thea F. Van De Mortel (2009). The Turkish validity and reliability of the Hand Hygiene Belief Scale and Hand Hygiene Practice Inventory were conducted by Karadağ et al. The Hand Hygiene Belief Scale and Hand Hygiene Practice Inventory were used to evaluate students' hand hygiene beliefs and practices. The Hand Hygiene Belief Scale is scored as "1=strongly disagree, 2=disagree, 3=not sure, 4=agree, 5=strongly agree" and consists of 22 items in total; the Hand Hygiene Practice Inventory is scored as "1=never, 2=sometimes, 3=often, 4=most of the time, 5=always" and consists of 14 items. Items 5,8,16,17,18,19,20 are evaluated in reverse (5=strongly disagree, 4=disagree, 3=not sure, 2=agree, 1=strongly agree).
