Psychometric Properties of the Multidimensional Perfectionism Scale of Hewitt in a Dutch-Speaking Sample: Associations With the Big Five Personality Traits

We administered the Dutch Multidimensional Perfectionism Scale of Hewitt and Flett (1991, 2004) in a large student sample (N = 959) and performed a confirmatory factor analysis to test the factorial structure proposed by the original authors. The existence of a method factor referring to the negatively keyed items in the questionnaire was investigated by including it in the tested models. Next, we investigated how the 3 perfectionism dimensions are associated with the Five-factor model (FFM) of personality. The 3-factor structure originally observed by the authors was confirmed, at least when a method factor that refers to the negatively keyed items was included in the model. Self-oriented and socially prescribed perfectionism were both distinguished by low extraversion and low emotional stability. Self-oriented perfectionism's positive relationship with both conscientiousness and openness to experience differentiated the 2 perfectionism dimensions from each other. Other-oriented perfectionism was not well-characterized by the Big Five personality traits.     

The Facts and Practices of Moral Responsibility

Strawsonians about moral responsibility often claim that our practices of holding morally responsible fix the facts of moral responsibility, rather than the other way round. Many have argued that such ‘reversal’ claims have an unwelcome consequence: If our practices of holding morally responsible fix the facts of moral responsibility, does this not imply, absurdly, that if we held severely mentally ill people responsible, they would be responsible? We provide a new Strawsonian answer to this question, and we explore the relation between reversal claims and (in)compatibilism.
