Aim:
To determine the factorial structure of the German Care Dependency Scale (CDS) for self-assessment in supported housing in Austria.
Background:
The CDS is a well-established tool for the assessment of care dependency. However, several versions of the scale showed different factorial structures depending on the country and the setting where they were applied. The factorial structure of the CDS, therefore, needed clarification prior to its application in supported housing.
Design:
Cross-sectional study.
Methods:
Self-assessments of care dependency were obtained from residents in supported housing in Austria. The factorial structure of the scale was determined by exploratory factor analysis. The resulting factor models were compared by confirmatory factor analyses with a single factor model regarding the best fit. CDS total score and sum scores of the identified factors were correlated with externally assessed care levels according to the Austrian care insurance.
Results:
48.2% of the residents in supported housing participated, but some of them were younger than 60. Exploratory factor analysis resulted in a three-factor model with two variants in the distribution of items, depending on whether people over 59 were included in the analysis or not. The second variant showed the best fit in confirmatory factor analysis. CDS total score and sum scores of the identified factors showed statistically significant correlations with externally assessed care levels.
Conclusion:
The three-factorial structure differentiates between various aspects of support and results from the particular characteristics of the setting and the care recipients. Several cross-loadings of items indicate an ambiguous understanding of support needs. It is suggested to modify the scale to adapt it to the target group and setting.
Implications For The Profession:
Self-assessments with a modified version of CDS in supported housing can be useful to identify the various support needs in this setting.
Patient Or Public Contribution:
No patient or public contribution.
