This study examined five aspects of change (or stability) in cognitive abilities in middle adulthood across a 12-year period. Data come from the Interdisciplinary Study on Adult Development. The sample consisted of N = 346 adults (43.8 years on average, 48.6% female). In total, 11 cognitive tests were administered to assess fluid and crystallized(More)
The present study examines whether the relationship between memory complaints and memory performance is better assessed by analyzing the mutual development. Five hundred participants, averaging 62.9 years of age at first measurement, were measured three times over 12 years. After establishing partial strong factorial invariance, correlations between levels(More)
BACKGROUND The WHO-surgical checklist is strongly recommended as a highly effective yet economically simple intervention to improve patient safety. Its use and potentially influential factors were investigated as little data exist on the current situation in Switzerland. METHODS A cross-sectional online survey with members (N = 1378) of three Swiss(More)
UNLABELLED BACKGROUND/STUDY CONTEXT: Typical intellectual engagement has been postulated as a trait-like construct that can explain interindividual differences in the extent of engaging in cognitively challenging tasks. Although formulated within the framework of cognitive development, the developmental aspects of typical intellectual engagement itself have(More)
The present study examined measurement invariance in the three anger expression subscales of the STAXI (Spielberger, 1988) with respect to gender. In a sample of 576 male and 531 female students, strict measurement invariance was found. For all three anger expression factors, no differences in variances or factor correlations were found. A large negative(More)
RATIONALE, AIMS AND OBJECTIVES Safety climate measurements are a broadly used element of improvement initiatives. In order to provide a sound and easy-to-administer instrument for the use in Swiss hospitals, we translated the Safety Climate Survey into German and French. METHODS After translating the Safety Climate Survey into French and German, a(More)
Safety Climate has been acknowledged as an unspecific factor influencing patient safety. However, studies rarely provide in-depth analysis of climate data. As a helpful approach, the concept of "climate strength" has been proposed. In the present study we tested the hypotheses that even if safety climate remains stable on mean-level across time, differences(More)
Background: Although surgical checklist use is not new in Switzerland, compliance and actual use fall short behind expectations taking scientific recommendation as standard. A national media campaign to raise awareness, inform experts, and change professional norms and standards on national level about checklist use was conducted. The aim of this study was(More)
Use of the surgical checklist in Switzerland is still incomplete and unsatisfactory. A national improvement program was developed and conducted in Switzerland to implement and improve the use of the surgical safety checklists. The aims of the implementation program were to implement comprehensive and correct checklist use in participating hospitals in every(More)
