Abstract
Objectives: The current study aimed to develop a measure of positive and negative beliefs in non-suicidal self-injury (NSSI), the Self-Harm Beliefs Scale (SHBS). A secondary aim was to explore the impact of these beliefs on NSSI behaviour. Design: The study adopted a cross-sectional design. Methods: Adults (n=98) with a history of NSSI were recruited from general and clinical populations across the North-West of England. The relationship between beliefs and NSSI behaviour (i.e. current NSSI, NSSI severity and future likelihood of NSSI) were assessed. The impact of NSSI beliefs on shame and mental well-being were also explored. Results: The SHBS demonstrated good reliability and convergent validity. Individuals with current and historic experience of self-harm endorsed positive and negative beliefs about NSSI. Increased endorsement of positive beliefs appeared to predict current NSSI behaviour as well as future likelihood of NSSI. Both positive and negative beliefs were significant predictors of shame however, only negative beliefs significantly predicted mentalwell-being. NSSI beliefs did not appear to significantly predict NSSI severity. Conclusions: The SHBS is a reliable and valid measure of beliefs about NSSI and presents as a useful clinical and research tool. Exploring NSSI beliefs appears important for better understanding the maintenance of NSSI and improving treatment approaches for this population. Keywords: Non-suicidal self-injury (NSSI), positive beliefs, negative beliefs, shame, mental well-being
