This study examined the psychosocial factors impacting upon the rule-following behaviour of residents of a hostel providing crisis accommodation to women who are homeless. After their arrival, residents of a women's hostel (N=83) completed questionnaires assessing the theory of planned behaviour constructs of attitude, subjective norm, perceived behavioural control (PBC), and intentions related to rule following while residing at the hostel. Perceived resident group norms for rule following were assessed also. Follow-up staff evaluations of the target behaviour were completed after participants ceased their hostel residence. As expected, attitude, subjective norm, PBC, and group norm significantly predicted intention to follow hostel rules, and intention and PBC predicted rule-following behaviour. As rule following is a crucial requirement for continuation of their stay, these findings can inform strategies to improve the experiences and outcomes of women's short-term hostel stays.
