Item distribution, internal consistency and structural validity of the German language person-centred climate questionnaire - staff version (PCQ-G-S): a cross-sectional study.

BACKGROUND: Person-centredness is considered as best practice for people living with dementia. A frequently used instrument to assess person-centredness of a care environment is the Person-centred Climate Questionnaire (PCQ). The questionnaire comprises of 14 items with the three subscales a climate of safety, a climate of everydayness and a climate of community. AIM: The aim of the study is to describe the translation process of the English language Person-centred Climate Questionnaire (Staff version, Patient version, Family version) into German language (PCQ-G) and to evaluate the first psychometric properties of the German language Person-centred Climate Questionnaire- Staff version (PCQ-G-S). METHODS: We conducted a cross-sectional study. The three versions of the 14-item English PCQ were translated into German language (PCQ-G) based on the recommendations for cross-cultural adaption of measures. Item distribution, internal consistency and structural validity of the questionnaire were assessed among nursing home staff (PCQ-G-S). Item distribution was calculated using descriptive statistics. Structural validity was tested using principal component analysis (PCA), and internal consistency was assessed for the resulting subscales using Cronbach's alpha. Data collection took place from May to September 2021. RESULTS: A total sample of 120 nurses was included in the data analysis. Nine out of 14 items of the PCQ-G-S demonstrated acceptable item difficulty, while five times showed a ceiling effect. The PCA analysis demonstrated a strong structural validity for a three-factor solution explaining 68.6% of the total variance. The three subscales demonstrated a good internal consistency with Cronbach's alpha scores of 0.8 for each of the subscales. CONCLUSION: The analysis of the 14-item German version (PCQ-G-S) showed first evidence for a strong internal consistency and structural validity for evaluating staff perceptions of the person-centredness in German nursing homes. Based on this, further investigations for scale validity of the PCQ-G versions should be carried out.

Attitudes and knowledge of nurses working at night and sleep promotion in nursing home residents: multicenter cross-sectional survey.

BACKGROUND: Sleep disturbances are common in nursing home residents and challenging for their nurses. Knowledge about sleep and sleep promoting factors is essential to provide adequate sleep management, where nurses play a key role. Therefore, nurses' knowledge and attitudes towards sleep and sleep promoting interventions is important as enabling or inhibiting factor for successful sleep management. METHODS: A multicenter cross-sectional study was conducted among nurses working wholly or partially at night in nursing homes in Germany. Data were collected between February and April 2021 via online or paper and pencil questionnaires, comprising 56 items. Nursing homes were recruited through existing cooperation with the study centers as well as via nursing home registers. RESULTS: Finally, 138 nursing homes participated and 271 nurses completed the survey. Nurses agreed that sleep disturbances are an important topic with important impact on resident' health. Although, the assessment of sleep was seen as nurses' responsibility, only 40 nurses (14.7%) stated that residents' sleep was always documented. Only 21.7% reported the availability of policy documents providing guidance regarding the management of sleep disturbances. The vast majority (93.2%) reported never having received training about sleep and management of sleep disturbances after their basic nursing training. CONCLUSIONS: Our results indicate that nurses working at night can play an important role in residents' sleep promotion. The findings indicate nurses' educational needs regarding sleep and sleep promotion. Nursing homes should implement institutional guidelines in order to promote residents' sleep based on adequate evidence-based non-pharmacological interventions.
