A comparison of two approaches to the assessment of coping styles
1997
Abstract This study examined the association of coping style classifications based on (a) dispositional vigilance (VIG) and cognitive avoidance (CAV) and (b) trait anxiety and social desirability (SD). 281 subjects (123 men, 158 women) completed questionnaires to assess these variables. By applying median splits, subjects were divided into high and low scorers on each dimension. According to both classifications, four coping style groups were operationally defined on the basis of the respective dichotomized variables. Results yielded convergent assignments of repressers (low anxiety and high SD; low VIG and high CAV, respectively), sensitizers (high anxiety and low SD; high VIG and low CAV)…
Anxiety, coping strategies, and the processing of threatening information: Investigations with cognitive-experimental paradigms
2011
Abstract This review treats individual differences in anxiety and coping from several perspectives. It starts with the argument that structural considerations (often linked to trait concepts) and processing considerations (often linked to situational demands and actual behavior) are not fundamentally in opposition, but that global and uncontextualized trait concepts (e.g., trait anxiety) require revision to incorporate cognitive–affective units such as appraisals, goals, or self-regulatory competencies (cf. Mischel, 2004 ). The article then presents a personality-oriented coping theory (the model of coping modes; MCM; Hock and Krohne, 2004 , Krohne, 1993 , Krohne, 2003 ) which attempts to i…
Rigid and flexible modes of coping: Related to coping style?
1993
Abstract This study examined dispositional and situative antecedents of vigilant and avoidant coping behavior. Seventy-two subjects were classified in coping style on the basis of their responses to the vigilance and cognitive avoidance scales of the Mainz Coping Inventory (MCI, Krohne, 1989), and alternatively, on their trait anxiety and defensiveness scores (cf. Weinberger, Schwartz, & Davidson, 1979). In a subsequent laboratory task, subjects were exposed to various conditions of predictability of an aversive event. In anticipation of an aversive loud tone, coping behavior was operationally defined as choosing to listen either to a warning channel (i.e., vigilance) or instead to music (i…
Coping variables as predictors of perioperative emotional states and adjustment
1996
Abstract Surgery, regardless of its kind and severity, can be regarded as a major stress situation for any patient. High preoperative emotional arousal may negatively influence adaptation during surgery and, consequently, rate of postoperative recovery. In a series of previous studies, our research group analyzed the influence of dispositional and actual coping on subjective and objective stress indicators before, during, and after surgery. The present study investigates the influence of the dispositional coping variables vigilance and cognitive avoidance on actual surgery-related coping, state anxiety, and indicators of intra- and postoperative adjustment. The sample consisted of 42 male a…
Nonlinear dynamical aspects of the human sleep EEG.
1994
This article deals with the application of methods from the theory of nonlinear dynamical systems to EEG signals. Theoretical background, mathematical concepts and algorithms for the calculation of "non-linear parameters" are reviewed and influences of the structure of reconstructed data sets on the calculations are pointed out. We present results for the estimation of the correlation dimension D2 and the principal Lyapunov-exponent lambda 1 for sleep EEG data respectively from 10 and 15 healthy subjects corresponding to different sleep stages. Essentially, we found a statistically significant decrease of both D2 and lambda 1 as sleep moves towards slow wave stages. The values for REM sleep…
Kognitive Prozesse und dynamische Zeitstrukturen. Vorstellung eines Meßgerätes zur Untersuchung der Mikro-Vigilanz-Shift-(MVS-)Hypothese. Cognitive P…
2003
The psychophysiological measuring method for the determination of the auditory order threshold (OT) is steadily gaining in importance, both for the diagnosis and treatment of speech disorders. Observed intraindividual variability of (macro-) vigilance led to the hypothesis of discontinuous cognitive processing in the central nervous system. The base for the variability of microvigilance is hypothesized to be in the phase difference of the alpha rhythm. To test for this hypothesis, we developed an EEG-comparator, which allows for a phase-dependent triggering of external stimuli. In direct comparison with stochastic (i.e. non-phase-dependent) stimulus presentation, the threshold in phase-depe…
A prospective study of adverse drug reactions as a cause of admission to a paediatric hospital
1996
1A total of 512 consecutive paediatric hospital admissions of children 2 years old or less were evaluated to assess the extent and pattern of admission caused by suspected adverse drug reactions (ADRs). The proportion of suspected ADRs related to hospital admissions was 4.3%. 2The organ-systems most commonly implicated were the central nervous system (40.5%), digestive system (16.7%), and skin and appendages (14.3%). Together, they accounted for 71.5% of admissions attributed to ADRs. The most common clinical manifestations inducing admission were convulsions (4 cases), dizziness (4), vomiting (3), and tremor, fever, itching and apnoea (2 cases each). 3The four classes of drugs most frequen…
Predicting the risk of drug–drug interactions in psychiatric hospitals: a retrospective longitudinal pharmacovigilance study
2021
ObjectivesThe aim was to use routine data available at a patient’s admission to the hospital to predict polypharmacy and drug–drug interactions (DDI) and to evaluate the prediction performance with regard to its usefulness to support the efficient management of benefits and risks of drug prescriptions.DesignRetrospective, longitudinal study.SettingWe used data from a large multicentred pharmacovigilance project carried out in eight psychiatric hospitals in Hesse, Germany.ParticipantsInpatient episodes consecutively discharged between 1 October 2017 and 30 September 2018 (year 1) or 1 January 2019 and 31 December 2019 (year 2).Outcome measuresThe proportion of rightly classified hospital epi…
Polypharmacy and the risk of drug-drug interactions and potentially inappropriate medications in hospital psychiatry.
2021
PURPOSE The aim of this study was to analyze the epidemiology of polypharmacy in hospital psychiatry. Another aim was to investigate predictors of the number of drugs taken and the associated risks of drug-drug interactions and potentially inappropriate medications in the elderly. METHODS Daily prescription data were obtained from a pharmacovigilance project sponsored by the Innovations Funds of the German Federal Joint Committee. RESULTS The study included 47 071 inpatient hospital cases from eight different study centers. The mean number of different drugs during the entire stay was 6.1 (psychotropic drugs = 2.7; others = 3.4). The mean number of drugs per day was 3.8 (psychotropic drugs …
ALDEN, an Algorithm for Assessment of Drug Causality in Stevens–Johnson Syndrome and Toxic Epidermal Necrolysis: Comparison With Case–Control Analysis
2010
Epidermal necrolysis (EN)--either Stevens-Johnson syndrome (SJS) or toxic EN (TEN)--is a severe drug reaction. We constructed and evaluated a specific algorithm, algorithm of drug causality for EN (ALDEN), in order to improve the individual assessment of drug causality in EN. ALDEN causality scores were compared with those from the French pharmacovigilance method in 100 cases and the case-control results of the EuroSCAR study. Scores attributed by ALDEN segregated widely. ALDEN pointed to a "probable" or "very probable" causality in 69/100 cases as compared to 23/100 with the French method (P < 0.001). It scored "very unlikely" causality for 64% of medications vs. none with the French metho…
