  A dimensional diagnostic system for personality disorders (PD) postulates continuous transition from normal to disordered personalities (continuity hypothesis) and universal validity of basicA dimensional diagnostic system for personality disorders (PD) postulates continuous transition from normal to disordered personalities (continuity hypothesis) and universal validity of basic personality dimensions (universal hypothesis). The present study investigates the validity of Leonhard's concept of attenuated personalities that define a conceptual link between normal personality dimensions and PD. Nine possible continuous transitions between three conceptual levels (Big Five personality factors, nine attenuated personality traits, nine PD) were tested by questionnaire data obtained from a mentally healthy (n = 166) and a clinical sample (n = 78). Both samples differed significantly in nearly all variables. However, they showed substantial similarity concerning the (in)validity of single continua and the complex structure of all variables as analyzed by multidimensional scaling. The concept of attenuated personalities could be validated for six out of nine tested continua and can be recommended for application in dimensional models of personality and personality disorders.

Data have been collected in a mentally healthy (n = 479), a depressed (n = 171) and a schizophrenic (n = 139) sample. Conventional psychometric criteria and a facet analytical methodology have been applied. The resulting questionnaire "Modular System for Quality of Life" (MSQoL) consists of a core module with 47 items (one "G-factor" and six subdimensions), which is sufficiently valid for all three samples. Additionally, there are four specific modules (demography, family, partnership, profession). No specific modules can be identified for the psychopathological subgroups. The validated radex structure for subjective QoL offers the opportunity for a cumulative research design and for adaptations to the actual setting.
