Fine-Needle Aspiration (FNAB) Molecular Analysis for the Diagnosis of Papillary Thyroid Carcinoma through BRAFv600E mutation and RET/PTC rearrangement
2007
Objective: To evaluate BRAFV600E mutation on consecutive fine-needle aspiration biopsy (FNAB) specimens in order to assess FNAB’s usefulness in preoperative papillary thyroid carcinoma (PTC) diagnosis with the contemporaneous analysis of RET=PTC1 and RET=PTC3 rearrangements obtained from ex vivo thyroid nodules. Design: Thyroid FNABs from 156 subjects with nodules and 49 corresponding surgical samples were examined for the presence of BRAF mutation by real-time allele-specific polymerase chain reaction, confirmed with the use of a laser pressure catapulting system. Samples were also examined for RET=PTC rearrangements. The results were compared with the cytological diagnosis and histopathol…
Assessing Anxiety with Extrinsic Simon Tasks
2006
This article introduces two new indirect measures of anxiety that are based on the Extrinsic Affective Simon Task (EAST; De Houwer, 2003 ). The EAST differs from the more established Implicit Association Test (IAT; Greenwald, McGhee, & Schwartz, 1998 ) in that participants' responses to different trials within one block of trials are compared rather than performance between two different blocks of trials. Two studies led to the following results: (a) Both extrinsic Simon tasks for assessing anxiety showed only moderate internal consistencies, (b) one of the two tasks showed at least some convergent validity with an IAT for assessing anxiety, and (c) both tasks were dissociated from sel…
Strength of memory encoding affects physiological responses in the Guilty Actions Test
2009
The Guilty Actions Test (GAT) is a valid and scientifically sound technique of forensic psychophysiology that allows for the detection of concealed memories. However, its application has been challenged because the results might be affected by the culprit's forgetting of crime details as well as the leakage of information to innocents. In the current study, these aspects were examined by varying the amount of time between a mock crime and the subsequent GAT, as well as by contrasting culprits with informed innocents. It turned out that culprits specifically forgot peripheral crime details during a period of 2 weeks whereas informed innocents showed similar forgetting for all details. As a c…
The effect of prosocial priming in the presence of bystanders.
2013
This study investigated the influence of priming and bystander apathy on helping behavior. After priming prosociality through a scrambled sentences test, participants encountered a woman who dropped the books she was carrying. Helping behavior in bystander and no-bystander conditions was tested. The results showed that people in a prosocial-prime condition were more likely to help than people in a neutral-prime condition, and that the effect of priming persists even in the presence of bystanders.
Some physiological and psychological characteristics of myopic and non-myopic young men.
2009
As a part of a research project on the health and functional capacity of men at different ages a comparison of selected physiological and psychological characteristics of myopic and non-myopic 31–35 year-old men was made. The random sample studied consisted of 31 myopic and 100 non-myopic men. It was found that the body mass index and fat content were lower among the myopic than among the non-myopic. No significant differences were found in the elastic properties of skin, in blood pressure or in haematological assays studied between the groups. With respect to physical performance it was observed that the myopic had a higher aerobic capacity whereas there were no significant differences in …
A non-randomised trial of an art therapy intervention for patients with haematological malignancies to support post-traumatic growth
2012
The aim of this study was to determine the effect of art therapy on post-traumatic growth in patients with haematological malignancies in a non-randomised trial ( n = 36, intervention group; n = 129, control group). Art therapy was administered over a period of 22 weeks in small groups. Post-traumatic growth was measured with the Stress-Related Growth Scale. After controlling for the effect of potential confounders, no difference in post-traumatic growth was observed between the intervention and control groups after 22 weeks. There was no evidence for an effect of weekly group sessions with art therapy on post-traumatic growth in patients with haematological malignancies.
Effectiveness of the Cognitive Differentiation Program of the Integrated Psychological Therapy
2011
The aim of the current pilot study was to compare two strategies in the application of the cognitive differentiation program of Integrated Psychological Therapy for people with schizophrenia. Twenty-six outpatients were randomly assigned to the application of the program in group sessions (CDg), or to its application in individualized sessions (CDi). The program provides cognitive exercises to promote better performance in cognition, and both groups of participants completed the same number of exercises following the same number of sessions per week. Outcomes were assessed on neuropsychological measures of attention, executive functioning and everyday memory, and everyday functioning. Effec…
Temporal stability of the implicit association test-anxiety.
2005
The Implicit Association Test-Anxiety (IAT-Anxiety; Egloff & Schmukle, 2002) provides an indirect assessment of anxiety by measuring associations of self (vs. other) with anxiety-related (vs. calmness-related) words. In 3 studies (using 3 independent samples), we examined the temporal stability of the IAT-Anxiety. In Study 1, 65 participants responded twice to the IAT-Anxiety with a time lag of 1 week. The test-retest correlation was .58. In Study 2 (N = 39), we extended the time interval between test and retest to 1 month and this yielded a stability coefficient of .62. In Study 3 (N = 36), we examined the long-term stability (time lag: 1 year) of the IAT-Anxiety and this showed a correlat…
Development of a new measure for assessing insight: Psychometric properties of the insight orientation scale (IOS)
2015
Abstract Introduction Given the centrality of insight in promoting change, the relevance of measures for assessing this construct has become increasingly clear. This paper describes a new self-report measure for assessing some of the characteristics of insight, the insight orientation scale (IOS). Aims In study 1, we evaluated the factor structure and the reliability of the scale. In study 2, we analyzed the concurrent and discriminant validity of the scale in patients with different clinical diagnoses. Methods In study 1 participants were 600 individuals (41.1% male, 58.9% female) with a mean age of 33.95 years (SD = 13.04). In study 2 participants were 136 individuals divided into the fol…
Predictors of neurocognitive impairment at 3years after a first episode non-affective psychosis
2013
Abstract Background Neurocognitive impairment is a core component of schizophrenia. However, patients show great variability in the level and course of deficits. The goal of the present longitudinal study was to identify predictors of neurocognitive impairment in first episode psychosis patients. Methods N eurocognitive performance was analyzed in a cohort of 146 patients 3 years after a first episode non-affective psychosis. Subgroups, impaired vs. unimpaired, were compared on baseline clinical, neuropsychological, premorbid and sociodemographic characteristics. Results Fifty-nine percent of participants presented general neurocognitive impairment and regression analyses demonstrated that …
