Factor structure in the Camberwell Assessment of Need

  • Erik Wennström (a1), Dag Sörbom (a2) and Frits-Axel Wiesel (a3)
Abstract
Background

In order to define needs for care of people with severe mental illness, the Camberwell Assessment of Need (CAN) is focused on measuring personal and social functioning. However, previous studies of the CAN have given inconsistent results in terms of what variables are actually being measured.

Aims

To investigate the factor structure of the CAN.

Method

Assessments of 741 out-patients (mean age 45.5 years, 50% females) with severe mental illness (68% schizophrenia or other psychotic disorder) were used in an exploratory maximum likelihood factor analysis.

Results

Support was found for a three-factor model, comprising 13 of the 22 variables in the CAN, with the factors corresponding to functional disability (7 variables), social loneliness (3 variables) and emotional loneliness (3 variables). The remaining variables did not load on any factor.

Conclusions

Exploratory factor analysis revealed three homogeneous dimensions in the CAN that may represent functional disability and two aspects of social health.
