Methods The study design consisted of direct observations during a pre-intervention period, an intervention phase introducing motivational signs promoting stair use at points of decision and a post-intervention period. Results The proportion of students who took the stairs on average differed significantly between baseline and intervention phase I (χ2(1) = 12.2; p = .001; Phi = 0.078), baseline and intervention phase II (χ2(1) = 17.3; p = .001; Phi = 0.093), and baseline and post-intervention (χ2(1) = 9.9; p = .002; Phi = 0.074). Conclusions Simple and cost-effective interventions can increase stair use of university students.This study was concerned with associations between narcissism, childhood trauma, dissociation, attachment styles, and depression among young adults. Childhood Trauma Questionnaire, Dissociative Experiences Scale (DES), Relationship Styles Questionnaire, Beck Depression Scale, and the Five-Factor Narcissism Questionnaire were administered to 422 college students. Multivariate analyses revealed that childhood sexual abuse, physical neglect, both fearful and secure attachment styles, dissociation, and male gender predicted grandiose narcissism. Vulnerable narcissism was predicted by preoccupied attachment, depression, and female gender. Dissociative taxon members (n = 133, 31.5%) had elevated scores on all childhood trauma types, fearful attachment, and both vulnerable and grandiose narcissism. While there was a link between bodily childhood maltreatment, dissociation, and grandiose narcissism, vulnerable narcissism was related to loss of perceived security in relationships and depression. Representing ambivalence and an indirect link between childhood trauma and vulnerable narcissism, depression was associated with both emotional neglect and overprotection-overcontrol, and fearful and preoccupied at
