Predicting uptake of housing services: The role of self-categorization in the theory of planned behaviour.

Abstract: The theory of planned behaviour (TPB) and self-categorization theory (SCT) were used to predict homeless people's (n = 80) uptake of housing support services. Homeless people's uptake behaviour was measured one year after a TPB/SCT-based interview schedule was administered. Congruent with previous research, TPB variables were influential predictors of both intention and behaviour. However, the addition of self-categorization variables, such as friendship group norms and identification as a housing support service user, significantly increased the rate prediction for both intention and behaviour, respectively. The implications of the research are firstly, that social cognition models are useful for understanding uptake of housing support services; and secondly, the addition of self-categorization variables aids in exploring the central role that social norms play in understanding the uptake of these services. These findings are discussed in terms of their impact on theory and practice
