Development and Validation of the Affect Intolerance Scale to Assess Maladaptive Beliefs and Avoidance of Emotion

Abstract

Cognitive processes are considered integral to the conceptualisation of emotional disorders and distress. Contemporary models have emphasised the importance of individual differences in the interpretation of internal events, including emotions. Maladaptive beliefs about emotional experience may motivate unhelpful control strategies, and impact negatively on psychological wellbeing. Building on existing measures of emotion, an integrative scale was developed to assess a range of maladaptive beliefs about the experience of negative emotions. Psychometric evaluation provided preliminary support for the reliability and validity of the Affect Intolerance Scale (AIS). Furthermore, the scale demonstrated a unique relationship with clinical symptomatology (i.e., depression, anxiety, stress and worry) above and beyond existing measures assessing dimensions of emotional experience. Potential utility of the measure for clinical practice and avenues for future research are discussed.
