Validation of the NOSCA - nurses' observation scale of cognitive abilities.

To examine the psychometric properties of the Nurses' Observation Scale for Cognitive Abilities. Nurses' Observation Scale for Cognitive Abilities is a behavioural rating scale comprising eight subscales that represent different cognitive domains. It is based on observations during contact between nurse and patient. Observational study. A total of 50 patients from two geriatric wards in acute care hospitals participated in this study. Reliability was examined via internal consistency and inter-rater reliability. Construct validity of the Nurses' Observation Scale for Cognitive Abilities and its subscales were explored by means of convergent and divergent validity and post hoc analyses for group differences. Cronbach's αs of the total Nurses' Observation Scale for Cognitive Abilities and its subscales were 0·98 and 0·66-0·93, respectively. The item-total correlations were satisfactory (overall > 0·4). The intra-class coefficients were good (37 of 39 items > 0·4). The convergent validity of the Nurses' Observation Scale for Cognitive Abilities against cognitive ratings (MMSE, NOSGER) and severity of dementia (Clinical Dementia Rating) demonstrated satisfactory correlations (0·59-0·70, p < 0·01), except for IQCODE (0·30, p > 0·05). The divergent validity of the Nurses' Observation Scale for Cognitive Abilities against depressive symptoms was low (0·12, p > 0·05). The construct validity of the Nurses' Observation Scale for Cognitive Abilities subscales against 13 specific neuropsychological tests showed correlations varying from poor to fair (0·18-0·74; 10 of 13 correlations p < 0·05). Validity and reliability of the total Nurses' Observation Scale for Cognitive Abilities are excellent. The correlations between the Nurses' Observation Scale for Cognitive Abilities subscales and standard neuropsychological tests were moderate. More conclusive results may be found if the Nurses' Observation Scale for Cognitive Abilities subscales were to be validated using more ecologically valid tests and in a patient population with less cognitive impairment. Use of the Nurses' Observation Scale for Cognitive Abilities yields standardised, reliable and valid information about patient's cognitive behaviour in daily practice. The Nurses' Observation Scale for Cognitive Abilities aids in tailoring nursing interventions to patients' specific cognitive needs. We advocate the implementation of the Nurses' Observation Scale for Cognitive Abilities both in research and at geriatric units in acute care hospitals.

Delirium-O-Meter: a nurses' rating scale for monitoring delirium severity in geriatric patients.

Delirium is a common psychiatric disorder in general hospital elderly patients. Several delirium screening tests exist. Few nurse based delirium severity measures are available. The aim of this study was to evaluate the Delirium-O-Meter, a new nurses' behavioural rating scale that is an efficient and sensitive measure of delirium severity. Analysis of cross sectional and repeated assessments data. Participants were 92 elderly general hospital patients; 56 with delirium, 24 with dementia or other cognitive disturbances (no delirium) and 12 with other psychiatric disorders or no mental disorder. Measures were the Delirium-O-Meter (DOM), Delirium Rating Scale-Revised version (DRS-R-98), Delirium Observation Scale (DOS), Behavioural observation scale for geriatric inpatients (GIP) and Mini Mental State Examination (MMSE). The majority of DOM items show a (near-) normal score distribution. Reliability of the DOM was high; Cronbach's alpha values ranged from 0.87-0.92; Intra Class Correlation (ICC) range was 0.84-0.91 for total scores and 0.40-0.97 for item scores. Factor analysis produced a 'Cognitive/Motivational' factor explaining almost half of variance and a smaller 'Psychotic/Behavioural' factor. The two-factor model results support the conceptual distinction between hyperactive and hypoactive delirium. DOM observations differentiated delirium from non delirium patients. DOM total scores were highly related to the DRS-R-98, DOS, MMSE and GIP apathy and cognitive sub scales, but less so to the GIP affective disturbances subscale, indicating convergent and divergent validity. Temporal difference scores calculated for DRS-R-98 and DOM assessments on subsequent days were also highly related (rho = 0.80-0.95). The newly constructed DOM is a brief and valid nurses' behavioural rating scale that can be useful for measuring different aspects of delirium and for efficiently monitoring delirium severity in elderly patients.
