Co-occurrence of substance use disorders (SUDs) and posttraumatic stress disorder (PTSD) is extremely common and is associated with elevated dropout and relapse rates. Given that PTSD/SUD co-occurrence rates among veterans have been found to be as high as 55?75%, it is important to identify mechanisms that may affect the interplay of both disorders. Emotion dysregulation (ED) presents a candidate mechanism that may underlie poor treatment response in co-occurring PTSD/SUD. This article proposes a transdiagnostic emotion regulation framework that considers ED conceptualized as a combination of low ability to tolerate emotional distress (low distress tolerance) and difficulties in the goal-directed use of emotion regulation strategies as a key risk factor in co-occurring PTSD/SUD. The authors review empirical findings from self-report and laboratory-based studies of ED in PTSD. They describe psychological explanations of the emotion-substance relationship and review studies documenting ED in SUDs and in co-occurring PTSD/SUD. The literature on ED in PTSD/SUD suggests that (a) patients with PTSD may resort to substances to cope with trauma-related symptoms due to ED, and (b) ED may maintain SUD symptoms and interfere with psychological treatment. Longitudinal studies on bidirectional relationships between ED and substance use in PTSD are needed, particularly research examining the course of ED in PTSD patients who use substances versus those who do not. 相似文献

This essay concerns the question of how we make genuine epistemic progress through conceptual analysis. Our way into this issue will be through consideration of the paradox of analysis. The paradox challenges us to explain how a given statement can make a substantive contribution to our knowledge, even while it purports merely to make explicit what one’s grasp of the concept under scrutiny consists in. The paradox is often treated primarily as a semantic puzzle. However, in “Sect. 1” I argue that the paradox raises a more fundamental epistemic problem, and in “Sects.1 and 2” I argue that semantic proposals—even ones designed to capture the Fregean link between meaning and epistemic significance—fail to resolve that problem. Seeing our way towards a real solution to the paradox requires more than semantics; we also need to understand how the process of analysis can yield justification for accepting a candidate conceptual analysis. I present an account of this process, and explain how it resolves the paradox, in “Sect. 3”. I conclude in “Sect. 4” by considering the implications for the present account concerning the goal of conceptual analysis, and by arguing that the apparent scarcity of short and finite illuminating analyses in philosophically interesting cases provides no grounds for pessimism concerning the possibility of philosophical progress through conceptual analysis. 相似文献

Evaluating salespeoples' performance is an important task for sales managers. However, little is known about what bases are used by sales managers to evaluate the performance of their salespeople. A study was conducted to determine the bases actually used by sales managers and the results were compared with a study conducted in 1983. Findings indicate more emphasis on profit and cost control, a continued reliance on qualitative measures, and a wide variety of bases being utilized to evaluate the performance of salespeople. Furthermore, the stability of results, across a wide variety of respondent job titles as well as business types and sizes, indicates a good deal of generalizability to other firms. 相似文献

Abstract Measures of attitude concerning exposure to the sun, and judgements of risk and other beliefs concerning skin cancer and four other problems (stomach cancer, deafness, AIDS and sunstroke) were obtained from a questionnaire completed by 176 university students. Subjects also estimated the incidence of each problem using one of three response formats. The highest incidence estimates were obtained when subjects were asked to guess at an absolute number, and the lowest when they used a scale which differentiated between lower frequencies, while grouping higher frequencies into a single response category. The effect of the response scale format, however, did not generalize to other ratings of personal risk. Subjects' ratings of their personal risk, compared with their peers, showed an optimistic bias over the five problems as a whole, particularly for AIDS, but not reliably so in the case of skin cancer. Optimism was inversely related to the amount of thought given to each problem. Men and women did not differ overall in their optimism regarding their own risk of skin cancer. However, differences as a function of gender and optimism were found on various behavioural attitudes. The results are discussed in relation to a tendency of disregard base-rates in subjective risk judgements, unrealistic optimism, and implications for health education. 相似文献

Objective: This study tested whether social cognitions from the reasoned action approach (RAA) can be reliably measured in a sample of primary school children (aged 4–6 years) and whether these RAA measures are predictive of physical activity.Design: Longitudinal observational study with repeated measures over six months.Measures: RAA variables were measured using a novel choice paradigm between physically active and sedentary pastimes. Relative reinforcing value, covariates (sex, age, deprivation and BMI) and physical activity by accelerometry (primary outcome) were also measured.Results: RAA cognitions could be measured with acceptable retest reliability and discriminant validity and social norms regarding parents and teachers (but not friends) were correlated with physical activity and change in physical activity when relative reinforcing value and other covariates were controlled for.Conclusions: RAA cognitions can be reliably measured in primary school children aged 4–6 and RRA measures appear useful in understanding children’s activity choices and may potentially inform future interventions. 相似文献

Abstract The fear of dental treatment in adults can be characterised in several ways, loosely related, such as anticipating being afraid, avoiding dental check-ups and seeking treatment only under general anaesthesia. Defined thus, at least a quarter of adults are highly afraid of dentistry. The feared experiences are many, including most frequently, pain. Several studies have shown that anxious patients experience less pain during treatment than they expect. It remains to be confirmed that these are typical experiences because other studies show that local anaesthesia can fail to protect patients from sudden pain in 13% of treatments on average. Expectations of pain are highly resistant to change, the result probably of several influences including distortion in recall of pain-free treatment, intermittent experience of sudden severe pain, expecting pain in order to reduce its impact, and uncertainty about treatment. It has yet to be shown that experience free of discomfort can reduce these expectations. However, relaxation instructions and information about pain management and stop signals can reduce pre-treatment fear. To prevent the onset and the maintenance of anxiety: the prevention of pain is essential; controlled behavioural studies of the treatment of pain and other experiences such as panics are needed. Finally, the need for new instruments to assess all aspects of fear of dentistry is described. 相似文献

Children with medium chain acyl coenzyme A dehydrogenase deficiency (MCADD) have been reported to be at high risk for neurocognitive deficits. However this has not been systematically studied and little is known about the exact nature of neuropsychological sequelae or of the impact of early diagnosis and screening on outcome. We examined cognitive and adaptive outcome in children with MCADD (N?=?38, age range: 2 years, 2 months – 10 years, 3 months) diagnosed either through a newborn screening program (tandem mass spectrometry/MSMS) or upon clinical presentation. There was no evidence of overall intellectual impairment in either groups but there was some suggestion of poorer verbal and specific executive functioning (i.e., planning) abilities in the unscreened cohorts. Adaptive functioning was relatively intact with the exception of reduced Daily Living Skills in both our screened and unscreened groups. Early diagnosis and greater number of hospitalizations were related to higher verbal, communication, and socialization skills. Overall, our results highlight the importance of early diagnosis and management for children with MCADD. 相似文献
