Factor 1 represents (1) basic domains (items) that relate to basic care needs/support to sustain life and health (food and drink, accommodation cleanliness and comfort, personal cleanliness and comfort, personal safety). Factor 2 represents higher order domains that relate to aspects of quality of life beyond basic care needs and/or relate to a person’s sense of self and identity (social participation and involvement, occupation, control over daily life).
The correlation between the promax rotated factors was: 0.4407. This suggests that promax rotation is an acceptable solution (the correlation was higher than 0.30).
