Background: The present study explored the reliability, validity, and factor structure of a modified version of the Moral Disengagement Scale (MDS), which comprehensively assesses proneness to disengage from different forms of conduct specific to Australian adolescents. Methods: A sample of 452 students (Mage = 12.79; SD = 1.93) completed the modified MDS and the Australian Self-Report Delinquency Scale. A multistep approach was used to evaluate the factor structure of the MDS. The sample was divided into exploratory (n = 221) and cross-validation samples (n = 231). Principal component analysis was conducted with the exploratory sample and multiple factor solutions compared to determine the optimal factor structure of the modified MDS. The final factor solution was confirmed in the cross-validation sample using confirmatory factor analysis. Internal consistency of the final scale and convergent validity with the delinquency questionnaire was also assessed. Results: Analyses resulted in a 22-item MDS for use in Australia, with four factors mapping onto the four conceptual categories of moral disengagement. The individual subscales demonstrated adequate to good internal consistency, and the total scale also demonstrated high internal consistency (α = 0.87). Convergent validity of the scale was established. Conclusions: The 22-item Australian MDS is a reliable and valid instrument for use within an Australian population.

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.
