Participants will be selected by healthcare professionals who care for patients with dementia. At the first meeting, participants will be informed about the study, will be screened for inclusion criteria, and a written informed consent form will be obtained before testing.

Sense of Competence in Dementia Care Staff (SCIDS) Scale

This scale includes competence in the field of dementia clinical practice, knowledge, skills and attitudes regarding dementia care.

Scoring All items are scored from 1 (Not at all) to 4 (Very much). Higher scores mean a higher level of sense of confidence.

Scores are added up for items from 1 to 17 for the overall SOCID-S score (ranging from 17 to 68) and for the subscales as follows:

Professionalism: 7, 8, 9, 10, 12 (scores ranging from 5 to 20); Building Relationships: 1, 2, 3, 4 (scores ranging from 4 to 12); Care Challenges: 13, 14, 15, 17 (scores ranging from 4 to 12); and Sustaining Personhood: 5, 6, 11, 16 (scores ranging from 4 to 12)

Its correlation with Sense of Efficacy in Dementia Care Personnel will be conducted for construct validity.

Assurance (8 items = 16, 17, 18, 20, 21, 22, 23, 24), knowledge-skill (5 items = 9, 10, 11, 12, 15), being respectful (6 items = 1, 3, It consists of 4 subgroups and 24 items: 5, 6, 13, 19) and commitment (5 items = 2, 4, 7, 8, 14), and a 6-point Likert-type scale (1 = never, 2 = almost never, 3=sometimes, 4=usually, 5=most of the time, 6=always) is used for the responses.

As the subscale and total scale scores increase, the level of care quality perception of patients or nurses increases.
