Posttraumatic stress disorder (PTSD) is one of the most common psychiatric disorders diagnosed in U.S. veterans. PTSD is associated with high smoking prevalences and difficulty quitting in the general U.S. population. The current study reviewed research on smoking and PTSD in U.S. veteran samples to summarize past research and identify areas in need of additional inquiry. MEDLINE and PsycINFO searches identified papers on smoking in samples of U.S. veterans with PTSD published from January 2006 through December 2016. Thirty-four articles met all of the inclusion criteria: (a) part of the sample consisted of U.S. veterans with PTSD or PTSD symptoms, and (b) the study examined some aspect of smoking behavior. U.S. veterans with PTSD were more likely to report smoking, heavy smoking, nicotine dependence, and late-onset smoking compared to veterans without PTSD. Smoking behaviors (e.g., current smoking, heavy smoking, smoking expectancies) differed by PTSD symptoms and by combat exposure. Smoking cessation feasibility studies examined the integration of smoking treatment into PTSD clinics and found favorable outcomes. Future research on veterans with PTSD would benefit from extending topics beyond rates of smoking to better understand the treatment needs of veterans. Research on smoking-related behaviors can help identify areas to target for interventions.  相似文献

为探索运动速度和方向对碰撞时间(TTC)估计的影响,采用3运动速度×4运动方向的双因素设计开展了实验研究。结果发现,在相对慢速条件下,受试者TTC估计的准确性显著差于相对中速和相对快速条件;仅在相对慢速条件下受试者对竖直方向的TTC估计准确度显著差于水平方向、低估TTC的比例显著高于高估TTC的比例。结果表明,运动速度对TTC估计绩效指标的影响相对较强,运动方向对其影响相对较弱;两个因素的影响存在交互作用。  相似文献

为探讨青少年手机依赖、学业倦怠、应对方式与心理健康的关系及作用机制,采用手机依赖指数量表、初中生学习倦怠问卷、简易应对方式问卷和SCL-90心理症状自评量表,对黑龙江、天津、山东、河南、江西8所高校的在校大学生以及河南省2所初中、2所高中的中学生共1191名青少年进行测查。结构方程模型的分析结果表明:(1)手机依赖对青少年心理健康有显著的负向预测作用;(2)学业倦怠在手机依赖和心理健康之间发挥部分中介作用;(3)消极应对方式调节了手机依赖通过学业倦怠影响青少年心理健康中介作用的后半段路径,相对于低消极应对的青少年,中介作用在高消极应对的青少年中更显著。该研究结果对维护和促进手机移动互联网时代青少年心理健康具有积极启示意义。  相似文献

Antecedent conditions of cycling have been extensively studied, yet barriers that prevent individuals from choosing bicycle transportation are less known. The present study, conducted on a sample of individuals who were both cyclists and drivers (N = 280), investigated whether dependence on car transportation significantly reduces cycling frequency. It also assessed the predictive validity of a larger set of cycling determinants that included moral, objective environmental, demographic and car-related variables. Responses were analyzed using a structural equation modeling approach. Results show that moral considerations do little to predict cycling frequency and that car-related factors such as perceived behavioral control to reduce car use (β = 0.28) and car use habits (β = -0.27) have the strongest predictive power. Objective environmental factors such as temperature (β = -0.13) and altitude (β = -0.15) or demographic factors such as gender (β = 0.19) were also significant predictors of cycling frequency. The present study highlights a new perspective of understanding cycling behavior and pleads for the inclusion of car-related factors in its future conceptualizations and interventions to encourage it.  相似文献

AimsTo provide quantitative summarized evidence on gender-related differences in self-reported problematic exercise (PE) symptoms.MethodsEligible studies were searched up to December 31, 2021 in the databases MEDLINE, Current Contents Connect, PsycINFO, Web of Science, SciELO, and Dissertations & Theses Global. Studies were considered eligible if they included information that allowed the calculation of the differences of interest as expressed by either the aggregate or subscales scores of the main self-reported instruments of PE identified by previous research (i.e., Commitment to Exercise Scale, Compulsive Exercise Test, Exercise Addiction Inventory, Exercise Dependence Questionnaire, Exercise Dependence Scale-Revised, and Obligatory Exercise Questionnaire). Data were analysed using three-level meta-analytic models. Potential moderator variables were examined using meta-regressions.ResultsA total of 168 effect-sizes from 117 studies (N = 65,718) were retrieved. Results showed (i) small overall differences favouring males for the aggregate scores of the instruments (g = 0.105), (ii) small-to-moderate differences favouring females for symptoms involving withdrawal (g = 0.169 and 0.118), lack of exercise enjoyment (g = 0.226), and the employment of exercise as a means to ends such as health improvement (g = 0.222), mood management (g = 0.158 and 0.226), and body weight control (g = 0.453 and 0.465); and (iii) small differences favouring males for symptoms involving spending considerable amount of time in the activity (g = 0.250), exercising with greater volume/intensity than planned (g = 0.254), a need for increased amounts of exercise to achieve the desired effect (g = 0.291), loss of control over the behaviour (g = 0.101), reduction or cessation of other activities because of exercise (g = 0.323), and continue to exercise despite physical and/or psychological issues being caused or exacerbated by this behaviour (g = 0.243).ConclusionsAdopting a gender-informed perspective may be needed both in the professional praxis of exercise and health practitioners prescribing and guiding exercise practice and in the design of prevention and treatment efforts aimed at avoiding the occurrence of PE.  相似文献

酒精性肝病是导致我国肝脏损害的第二大原因,已成为最严重的健康问题之一。我国已经迎来了酒精性肝病的高峰时期,并将会持续增长,卫生系统将面临巨大的压力。然而,对于酒精性肝病本身,还存在着诊断、治疗、预防等众多医学困惑;饮酒的危害不仅仅局限在肝脏,还可引起全身多器官的损害;酒害也早已超越了医疗界,是一个严重的社会问题。对于酒精性肝病的防治需要全社会共同参与,并且将是一条极其漫长而艰难的路程。  相似文献

The Wisconsin card sort task (WCST) is a commonly used neuropsychological test of executive or frontal lobe functioning. Traditional behavioral measures from the task (e.g., perseverative errors) distinguish healthy controls from clinical populations, but such measures can be difficult to interpret. In an attempt to supplement traditional measures, we developed and tested a family of sequential learning models that allowed for estimation of processes at the individual subject level in the WCST. Testing the model with substance dependent individuals and healthy controls, the model parameters significantly predicted group membership, even when controlling for traditional behavioral measures from the task. Substance dependence was associated with (a) slower attention shifting following punished trials and (b) reduced decision consistency. Results suggest that model parameters may offer both incremental content validity and incremental predictive validity.  相似文献

Abstract: Response‐dispositional (RD) properties are standardly defined as those that involve an object's appearing thus or thus to some perceptually well‐equipped observer under specified epistemic conditions. The paradigm instance is that of colour or other such Lockean “secondary qualities”, as distinct from those—like shape and size—that pertain to the object itself, quite apart from anyone's perception. This idea has lately been thought to offer a promising alternative to the deadlocked dispute between hard‐line ‘metaphysical’ realists and subjectivists, projectivists, social constructivists, or hard‐line anti‐realists. A chief source text is Plato's Euthyphro, where the issue is posed in ethical terms: do the gods infallibly approve virtuous acts on account of their divine moral omniscience or are virtuous acts just those the gods approve? Among the areas proposed as amenable to an RD approach are epistemology, ethics, political theory, and philosophy of mathematics. It is claimed that by making due allowance for the involvement of normalised or optimised human responses one can steer a course between the twin poles of an objectivist realism that places truth beyond our cognitive grasp and an epistemic conception that confines truth within the limits of humanly attainable proof, knowledge, or verification. Here I argue—on the contrary—that RD approaches can be shown to offer nothing more than a variant of the same old realist versus anti‐realist dilemma. That is, they work out either as a trivial (tautologous) claim that ‘truth’ simply equates with ‘best judgement’ in the ideal (quasi‐objective) limit or as the claim—advanced by anti‐realists like Michael Dummett—that we cannot form any adequate conception of objective (recognition‐transcendent) truths. After looking at this issue in various contexts of debate, I conclude that one useful (if pyrrhic) outcome is to demonstrate the non‐availability of any middle‐ground stance. We are left with the strictly unavoidable choice between a realist or objectivist approach and one that assimilates truth to the consensus of accredited best opinion. This latter amounts to a roundabout, elaborately qualified version of the anti‐realist case.  相似文献
