A review of research on prenatal depression effects on the fetus and newborn suggests that they experience prenatal, perinatal and postnatal complications. Fetal activity is elevated, prenatal growth is delayed, and prematurity and low birthweight occur more often. Newborns of depressed mothers then show a biochemical/physiological profile that mimics their mothers' prenatal biochemical/physiological profile including elevated cortisol, lower levels of dopamine and serotonin, greater relative right frontal EEG activation and lower vagal tone. Elevated prenatal maternal cortisol is the strongest predictor of these neonatal outcomes. Moderate pressure massage can alleviate these effects including reducing prematurity. 相似文献

Belief in life after death offers potential comfort in the face of inevitable death. However, afterlife belief likely requires not only an awareness of death but also body–self dualism—the perception that the self (e.g., the mind) is distinct from the physical, undeniably mortal, body. In turn, we hypothesized that mortality salience (MS) should heighten afterlife belief only when dualism is facilitated. Study 1 found that MS increased belief for people high, relative to low, in trait mind–body dualism. In Study 2, MS only increased belief when people first wrote about their thoughts and personality, which a pilot study confirmed facilitated dualistic belief, relative to thinking about the physical self. Study 3 used the brain–computer interface technology to induce a dualistic experience: MS increased belief when participants accurately “typed” without the use of their external body (i.e., no hands). Together, these findings support the position that mortality awareness and body–self dualism constitute a “why” and “how” of afterlife belief. Copyright © 2015 John Wiley & Sons, Ltd. 相似文献

The Depression Anxiety and Stress Scales: Reference data from a large psychiatric outpatient sample 下载免费PDF全文
Gordon Davies Peter Caputi Maria Skarvelis Nicola Ronan 《Australian journal of psychology》2015,67(2):97-104
The published norms for the Depression Anxiety and Stress Scale (DASS) give results for clinical populations that largely fall in the severe to very severe categories. As a result, within this population, the ability to compare the comparative contributions of the underlying emotional components is reduced. The present study presents results from a large general psychiatric outpatient population and provides percentile norms with confidence intervals for both the original DASS and the shorter 21‐item form. It is noted that both forms have high validity but that the correlations between scales are higher than those reported in non‐clinical populations. There was little variation between sexes but some variation of results with age with both younger and older cohorts having lower scores except for the Stress scale where there were higher scores in the older group. There is some evidence of a ceiling effect in the Depression and Stress scales. It was noted that nearly a quarter of patient scores fell within the originally defined normal range suggesting that the DASS would not be a particularly sensitive instrument in its previously reported use as a screening instrument for psychiatric illness. 相似文献

The identification of high-risk adolescent suicide attempters in a population of depressed and suicidal adolescents is of crucial importance. This retrospective study examined characteristics of suicidality (recent and lifetime, active and passive) and psychopathology (depression, aggression, impulsivity, stressful life events, SCL-90 dimensions) among four groups of depressed adolescent outpatients: (1) suicide attempters who required medical treatment (n = 84), (2) suicide attempters who did not require medical treatment (n = 57), (3) suicidal ideators who had never made a suicide attempt (n = 40), and (4) nonsuicidal patients (n = 44). Results indicate that the nonsuicidal group could be differentiated from the three suicidal groups on the basis of suicidality and psychopathology, and that the three suicidal groups could be differentiated from one another on the basis of suicidality but not psychopathology. These findings are discussed in terms of the usefulness of certain self-report measures of suicidality for identifying suicidal adolescents and for differentiating among them. Furthermore, the findings suggest that psychopathological factors do not determine which suicidal adolescents make a medically dangerous suicide attempt and which do not. 相似文献

Aim: This paper seeks to understand whether Maltese school counsellors are equipped to deal with dyslexic clients, considers whether specific strategies need to be used, and what positive effects, if any, counselling has on these clients. Previous studies: A literature review on self-concept and techniques on how to improve the self-concept of children with Learning Disabilities (LD)/Specific Learning Difficulties (SpLD) will place the current study in context. Method: Questionnaires (available from the authors on request) were distributed to all school counsellors on the island and analysed using content analysis. Findings: Findings from respondents indicate a need for more training, evidence-based knowledge of specific techniques when dealing effectively and successfully with dyslexic clients, specific specialised training to understand dyslexic clients and that counselling has a positive effect on dyslexic clients. 相似文献
