Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The introduction of new elements to the workspace is assumed to have a twofold impact on nursing care specialists exposed to the light ceiling: on the one hand, the levels of illuminance will have an instrumental function, allowing a correct and efficient performance of tasks to the nursing care specialists, thus contributing to a reduction of their perceived levels of stress. On the other hand, the mere presence of the light ceiling will have a symbolic function, signaling the commitment of the organization toward patient welfare and innovation. This will impact attitudes toward the organization like commitment to the workplace and meaning of work. Furthermore, this symbolic function will likely also impact the feelings of empathy toward the patients among nursing care specialists.
Following their work schedules, nursing care specialists will be anonymously allocated into 4 treatment groups:
1. working the early shift in rooms with an operating light ceiling irradiating LSA-1 (high circadian effective irradiances + blue Light Intervention) or LSA-2 (high circadian effective irradiances without blue light intervention)
2. working the late or night shift in rooms with an operating light ceiling irradiating LSA-1 (high circadian effective irradiances + blue Light Intervention) or LSA-2 (high circadian effective irradiances without blue light intervention)
3. working in rooms with an operating light ceiling irradiating LSA-3 (standard irradiances)
4. working in conventional rooms, in which no light ceiling has been installed (Control Group).
Main Hypothesis:
Nursing care specialists working under increased irradiance lighting may differ in the perceived levels of stress compared with nursing care specialists working under conventional irradiance lighting.
Secondary Hypotheses:
1. Nursing care specialists working under increased irradiance lighting receiving illumination with increased irradiance and phases of Blue-Enriched White light (LSA-1) differ in the perceived levels of stress and report lower perceived stress compared with nursing care specialists working under conventional irradiance lighting (LSA-3).
2. Nursing care specialists working under increased irradiance lighting receiving illumination with increased irradiance without phases of Blue-Enriched White light (LSA-2) differ in the perceived levels of stress and report lower perceived stress compared with nursing care specialists working under conventional irradiance lighting (LSA-3).
3. Nursing care specialists working in rooms with a newly installed light ceiling differ in their self-reported commitment to the workplace compared with nursing care specialists working in rooms in which the light ceiling has not been installed.
4. Nursing care specialists working in rooms with a newly installed light ceiling differ in their self-reported meaning of work compared with nursing care specialists working in rooms in which the light ceiling has not been installed.
5. Nursing care specialists working in rooms with a newly installed light ceiling differ in their self-reported empathy compared with nursing care specialists working in rooms in which the light ceiling has not been installed.
