Background/Objective
Unwanted mental intrusions (UMIs) are the normal variants of obsessions in Obsessive-Compulsive Disorder (OCD), preoccupations about defects in Body Dysmorphic Disorder (BDD), images about illness in Hypochondriasis (HYP), and thoughts about eating in Eating Disorders (EDs). The aim was to examine the similarities and differences in the functional links of four UMI contents, adopting a within-subject perspective. Method: 438 university students and community participants (Mage = 29.84, SD = 11.41; 70.54% women) completed the Questionnaire of Unpleasant Intrusive Thoughts (QUIT) to assess the functional links (emotions, appraisals, and neutralizing/control strategies) of the most upsetting UMIs with OCD, BDD, HYP and EDs-contents. Results: HYP-related intrusions caused the highest emotional impact, OCD-related intrusions were the most interfering, and EDs-related intrusions interfered the least. The four UMI were equally ego-dystonic. Women appraised OCD-related intrusions more dysfunctionally, but men appraised the four intrusive contents similarly. All UMI instigated the urge to “do something”, to keep them under control and/or neutralizing them. Conclusions: Similarities among the functional links of intrusions related to OCD, BDD, HYP and EDs contents support their transdiagnostic nature and they might contribute to understanding common factors in these disorders. 相似文献942.

Middle childhood is considered a sensitive phase for the development of both dependency and achievement-related problems. In order to target efficient prevention and treatment, it is necessary to identify unique associations with possible precursors. This study hypothesized that children’s dependency-related problems (i.e., separation anxiety and generalized anxiety) would uniquely relate to parental dependency-oriented psychological control and that children’s achievement-related problems (i.e., extrinsic motivation and maladaptive perfectionism) would uniquely relate to parental achievement-oriented psychological control. The study included 180 elementary school children. Results showed that higher levels of children’s separation anxiety uniquely related to more parental dependency-oriented psychological control, while higher levels of children’s extrinsic motivation uniquely related to more parental achievement-oriented psychological control. Contrary to the expectations, higher levels of children’s maladaptive perfectionism were associated with both dimensions of parental psychological control, and children’s generalized anxiety was not associated with any dimension. Study implications are discussed. 相似文献

To provide the three-way comparisons needed to test existing theories, we compared (1) most-stressful memories to other memories and (2) involuntary to voluntary memories (3) in 75 community dwelling adults with and 42 without a current diagnosis of posttraumatic stress disorder (PTSD). Each rated their three most-stressful, three most-positive, seven most-important and 15 word-cued autobiographical memories, and completed tests of personality and mood. Involuntary memories were then recorded and rated as they occurred for 2 weeks. Standard mechanisms of cognition and affect applied to extreme events accounted for the properties of stressful memories. Involuntary memories had greater emotional intensity than voluntary memories, but were not more frequently related to traumatic events. The emotional intensity, rehearsal, and centrality to the life story of both voluntary and involuntary memories, rather than incoherence of voluntary traumatic memories and enhanced availability of involuntary traumatic memories, were the properties of autobiographical memories associated with PTSD. 相似文献

Mood in humans is a complex phenomenon that integrates emotion (e.g. happiness and sadness), cognition, perception, ideation, and action in a coherent manner. In bipolar disorder extremes of mood (up or down) occur outside the normal range, in which all the above functions are coherently affected. Mood is controlled by a series of separate but interactive brain circuits that involve much of the brain, but particularly the limbic system. The question addressed in this paper is whether the coordination of all these separate systems into one coherent functional mood is mediated by non-linear dynamics acting between these systems as equal participants; or whether it is affected by a single master regulator controlling the others. The possible roles, as master regulators, of non-linear dynamically linked populations of neurons, and of the C1–C3 adrenergic nuclei in the medulla is discussed. 相似文献

Participants with posttraumatic stress disorder (PTSD) and participants with a trauma but without PTSD wrote narratives of their trauma and, for comparison, of the most-important and the happiest events that occurred within a year of their trauma. They then rated these three events on coherence. Based on participants’ self-ratings and on naïve-observer scorings of the participants’ narratives, memories of traumas were not more incoherent than the comparison memories in participants in general or in participants with PTSD. This study comprehensively assesses narrative coherence using a full two (PTSD or not) by two (traumatic event or not) design. The results are counter to most prevalent theoretical views of memory for trauma. 相似文献

Background
The role of glucocorticoids in extinction of traumatic memories has not been fully characterized despite its potential as a therapeutic target for acquired posttraumatic stress disorder (PTSD). The predator stress paradigm allows us to determine whether glucocorticoids mediate the extinction of both context-dependent and context-independent fear memories.Methods
Male C57BL/6J mice were exposed to a predator (cat) then repeatedly exposed to the predator stress context in the absence of the cat. Context-dependent (associative) fear memory was assessed as suppression of activity during re-exposure to the predator stress context without the cat (extinction trials). Context-independent fear (non-associative) was assessed seven days after extinction trials using measures of hyperarousal and anxiety-like behaviours in environments unlike the predator stress context. To assess the role of glucocorticoids, mice were injected with metyrapone (50 mg/kg) 90 min prior to extinction trials in predator stressed mice and context-dependent and context-independent fear memories were assessed. Finally, metyrapone-treated predator stressed mice were injected with corticosterone (5 or 10 mg/kg) immediately following extinction trials and context-dependent and context-independent fear memories were assessed.Results
Repeated re-exposure to the predator stress context without the cat present extinguished context-dependent fear memory, and also reduced hyperarousal, a generalized, chronic PTSD-like symptom. We show that extinction of context-independent predator stress-induced hyperarousal is dependent on endogenous glucocorticoids during the extinction trials. Furthermore, the inhibition of extinction by metyrapone on startle amplitude was reduced by exogenous administration of corticosterone following extinction trials. Overall, these data implicate glucocorticoids in the extinction of hyperarousal, a core symptom of PTSD. 相似文献949.
Aims: This study (1) profiled the well‐being of first year students entering one UK university, and (2) explored whether initial well‐being and year end academic performance were correlated. Method: A total of 117 students (mean age 21, 67% female) completed the Rosenberg Self‐Esteem Scale, Clinical Outcomes in Routine Evaluation‐General Population, and Liebowitz Social Anxiety Scale; academic achievement data were collected from academic records. Results: Almost a quarter of the sample reported quasi‐clinical levels of psychological distress and moderate to very severe social anxiety. Quasi‐clinical levels of psychological distress were associated with low self‐esteem and social anxiety. No statistically significant links were found between well‐being as assessed at the beginning of the first year and academic achievement at the end of the first year. Discussion: The failure to find a link in this study between initial well‐being and academic performance at the end of the first year suggests that further investigation is required to understand how academic achievement is related to student well‐being. 相似文献
