The aim was to extend recent findings of suggested temperamental features in attempted suicide and to explore possible domains of vulnerability to suicide risk after attempted suicide. Fifty-four psychiatric inpatients hospitalized after a suicide attempt underwent lumbar puncture for analysis of CSF 5-HIAA concentration and also completed the Karolinska Scales of Personality (KSP) before discharge from the hospital. Suicide attempters scored high on Somatic Anxiety, Psychic Anxiety, and Muscular Tension, and low on Socialization, findings that support recent findings in suicide attempters followed up after an emergency room visit. Five patients committed early suicide, i.e., within 3 years, and the overall long-term suicide mortality after attempted suicide was 13%. There were significant correlations between survival time among early suicides and CSF 5-HIAA (r = .87;p = .054), and the following KSP scale t scores: Somatic Anxiety (r = ?.96;p < .05), Impulsivity (r = ?.88; p < .05), and Socialization (r = .90; p < .05). KSP Socialization showed correlations with CSF 5-HIAA (r = .89; p = .046) among the early suicides. Features of temperamental vulnerability to suicide risk after attempted suicide might involve anxiety proneness, impulsivity, low socialization, and low CSF 5-HIAA. 相似文献

A large number of experiments in successive tests of episodic memory have focused on an experimental paradigm called recognition failure of recallable words. In this paradigm, a cued recall test follows a recognition test. Large amounts of data have revealed a lawful moderate dependence between recognition and cued recall. TECO (Sikstr?m, 1996b), a general connectionist theory of memory, has been applied for the phenomenon of recognition failure. This paper makes a strong claim that all possible pairwise combinations of successive tests between recognition, cued recognition, cued recall, and free recall follow a lawful relationship. The quantitative degree of the dependency predicted between these tests can be summarized in one function. Four experiments were conducted to test this claim. In line with the predictions, the results show that all pairwise combinations of these tests fit reasonably well with the proposed function. The TECO theory suggests theoretical insights into how recognition and recall may be divided into a recollection component, a familiarity component, and a cue-target integration component. 相似文献

A large number of experiments have found a moderate degree of dependence between subsequent tests of recognition and cued recall as described by the TW-function. This paper investigates the dependence in word pair recognition. Tests of word pair recognition are conducted with the subsequent test being free recall, cued recall, recognition, and cued recognition. The dependence is compared to subsequent tests of cued recognition (i.e. recognition of a target with the presence of a cue). The results are related to a general theory of memory called TECO (Target, Event, Cue, & Object, see Sikstr?m 1996b). This theory makes different quantitative predictions depending on the number of shared connections in the subsequent tests. Using a function suggested by TECO, different degrees of dependencies are predicted for pair and cued recognition. The predictions of the TECO-function show a non-significant deviation from observed data, whereas those of the TW-function deviate significantly in all conditions. 相似文献

The contribution of nonlinear dynamics to heart rate variability in healthy humans was examined using surrogate data analysis.
Several measures of heart rate variability were used and compared. Heart rates were recorded for three hours and original
data sets of 8192 R-R intervals created. For each original data set (n=34), three surrogate data sets were made by shuffling
the order of the R-R intervals while retaining their linear correlations. The difference in heart rate variability between
the original and surrogate data sets reflects the amount of nonlinear structure in the original data set. Heart rate variability
was analyzed by two different nonlinear methods, point correlation dimension and approximate entropy. Nonlinearity, though
under 10 percent, could be detected with both types of heart rate variability measures. More importantly, not only were the
correlations between these measures and the standard deviation of the R-R intervals weak, the correlation among the nonlinear
measures themselves was also weak (generally less than 0.6). This suggests that in addition to standard linear measures of
heart rate variability, the use of multiple nonlinear measures of heart rate variability might be useful in monitoring heart
rate dynamics. 相似文献

The purpose of this study is to estimate the percentage of mental health problems in a pediatric outpatient Norwegian clinic. We used the Strengths and Difficulties Questionnaire to screen for mental health problems. Families of children aged 4–11 took part in the study, and 380 out of 982 possible families consented to take part, and 349 families contributed with questionnaire data. The main referral reasons for the patients were asthma, eneuresis and stomach pain. Mothers reported that 17.4% of boys and 17.8% of girls displayed mental clinical problems. The prevalence of problems did not differ significantly between somatic diagnostic groups. Although the study has low participation, it underlines the necessity of screening all pediatric patients for mental health problems. Future research in pediatric clinics should include factors of psychology because pediatric problems are not caused by somatics alone. 相似文献

A comparison of coping strategies in patients with fibromyalgia,chronic neuropathic pain,and pain‐free controls 下载免费PDF全文

Patients suffering from chronic pain may benefit from learning adaptive coping strategies. Consensus on efficient strategies for this group of patients is, however, lacking, and previous studies have shown inconsistent results. The present study has examined coping strategies in two distinctly different groups of chronic pain patients and a group of healthy controls. Thirty neuropathic pain (NP) patients, 28 fibromyalgia (FM) patients, and 26 pain‐free healthy controls completed the Coping Strategy Questionnaire (CSQ‐48/27) and rated their daily pain. The results showed that FM and NP patients did not cope differently with pain. The only difference between the groups was that FM patients felt more in control of their pain than NP patients. Both patient groups used more maladaptive/passive coping strategies, but surprisingly also more adaptive/active coping strategies than healthy controls. However, FM patients with high levels of passive strategies felt less in control than FM patients with low levels of passive strategies. This was not seen in NP patients. An important implication for clinical practice is therefore that passive coping strategies should be restructured into active ones, especially for FM patients. Otherwise, the same psychological treatment model can be applied to both groups since they use similar coping styles. 相似文献

Child sexual abuse (CSA) investigations are complicated and few cases are prosecuted. The aim of the present study was to investigate judicial decisions in CSA investigations. Seventy‐one law students (42 females, 29 males) read a vignette depicting a CSA investigation, assessed the complainant's and the accused's credibility, and if the case should be prosecuted or not. The participants were assigned to one of four conditions defined by a 2 (evidence: high probative value vs. low probative value) × 2 (complainant demeanour: emotional vs. neutral) factorial design. Females assigned higher credibility to the complainant than did males and males assigned higher credibility to the accused than did females. Emotionality, but not evidential value, affected credibility judgements: Females believed less in the suspect when the child behaved in an emotional manner. Most participants (94.4%) thought that the case should be prosecuted, though only 73.2% believed that prosecution could be corroborated. Corroboration of prosecution was affected by evidential value, but not emotionality. The results indicate that the behavior of alleged crime victims might affect males and females differently, which in turn could lead to biased judicial decisions in CSA investigations. 相似文献
