Anxiety sensitivity in smokers with indicators of cardiovascular disease

There is growing recognition of the importance of understanding the nature of the associations between anxiety and cardiovascular disease (CVD), although limited research has examined mechanisms that may explain the anxiety-CVD link. Anxiety sensitivity (fear of anxiety-relevant somatic sensations) is a cognitive-affective risk factor implicated in the development of anxiety psychopathology and various behavioral risk factors for CVD, although has not been examined among individuals with CVD. Adult daily smokers (n = 619; 50.9% female; M_age = 44.0, SD = 13.67) completed an online survey that included the Anxiety Sensitivity Index-3 (ASI-3) and the Patient Health Questionnaire (PHQ). The presence of CVD was assessed via the presence of ≥1 of the following: heart attack, heart murmur, positive stress test, heart valve abnormality, angina, and heart failure. Smokers with CVD indicators (n = 66, 10.7%) had significantly higher scores on the ASI-3 (M = 33.5, SD = 22.15), relative to smokers without CVD (M = 22.0, SD = 17.92; Cohen’s d = .57). Those with CVD were significantly more likely to have moderate or high anxiety sensitivity (66.7%) relative to those without CVD (49.4%). Physical and social concerns about the meaning of somatic sensations were common among smokers with CVD.     

Association between tobacco use,depression, and anxiety: A cross-national study among university students from 30 low- and middle-income countries

This study aimed to investigate the association between tobacco use and depression and anxiety in a cross-national study among university students from 30 predominantly low- and middle-income countries. Self-report survey data were collected from 23 073 university students (58.0% female), with a mean age of 20.8 years (SD = 2.5). Following logistic regression analyses, tobacco using university students were more likely to have depressive symptoms and anxiety (posttraumatic stress symptoms = PTSS) than non-tobacco using students. Gender stratified analysis found associations between tobacco use and depressive symptoms were stronger among women than men. The associations between tobacco use and anxiety (PTSD) symptoms were stronger among men than women. In this large cross-national study, current tobacco use was significantly associated with depression and anxiety (PTSD) symptoms. Tobacco use prevention efforts can help alleviating mental health problems among university students.     

使用题组反应模型缓解局部题目依赖性对多阶段测验的危害

尽管多阶段测验(MST)在保持自适应测验优点的同时允许测验编制者按照一定的约束条件去建构每一个模块和题板,但建构测验时若因忽视某些潜在的因素而导致题目之间出现局部题目依赖性(LID)时,也会对MST测验结果带来一定的危害。为探究"LID对MST的危害"这一问题,本研究首先介绍了MST和LID等相关概念;然后通过模拟研究比较探讨该问题,结果表明LID的存在会影响被试能力估计的精度但仍为估计偏差较小,且该危害不限于某一特定的路由规则;之后为消除该危害,使用了题组反应模型作为MST施测过程中的分析模型,结果表明尽管该方法能够消除部分危害但效果有限。这一方面表明LID对MST中被试能力估计精度所带来的危害确实值得关注,另一方面也表明在今后关于如何消除MST中由LID造成危害的方法仍值得进一步探究的。     

He's gotta have it: shopping dependence and the homosexual male clothing consumer

Shopping is not always ‘fun’ and is not always ‘therapeutic’, yet, the negative aspects and motivations for this behaviour have received little attention. Consumers often may be dependent upon shopping activity to satisfy personal needs, such as emotional repair and self‐image, which are far removed from the acquisition and use of products. Not only may this dependence be dysfunctional in that it signals an individual's inability to control their shopping behaviour but also it may be symptomatic of more serious problems, such as compulsive and even addictive shopping. This paper explores this shopping dependence in the context of fashion clothing consumption. Male consumers are considered, with sexual orientation employed as an indicator of behaviour. Data from a survey of 225 homosexual and 225 heterosexual UK males suggest that homosexual males display clothes shopping dependence, and at a level that is significantly stronger than for heterosexuals. Younger males show a greater tendency to display such behaviour, with dependence declining with age for both groups. Managerial and research implications are considered.

多元整合元分析法评介

在传统元分析中, 每个研究只能提取一个效果量, 以满足各效果量相互独立的条件。若出现单个研究多效果量的情况, 就需要采用多元元分析技术予以处理。多元元分析主要包括多元线性模型法和多元整合法, 其中, 多元整合法是应用最为广泛的一种方法, 可较为有效地解决多效果量非独立性问题, 还可借助传统元分析的固定效应模型和混合效应模型进行统计分析。但多元整合法在应用中还存在着统计软件的开发问题、同质性Q检验显著性的稳定问题、不同质混合效果量的同质性检验的可行性问题。     

Stimulus dependence and cross-modal interference in sequence learning

A central issue in sequence learning is whether learning operates on stimulus-independent abstract elements, or whether surface features are integrated, resulting in stimulus-dependent learning. Using the serial reaction-time (SRT) task, we test whether a previously presented sequence is transferrable from one domain to another. Contrary to previous artificial grammar learning studies, there is mapping between pre- and posttransfer stimuli, but contrary to previous SRT studies mapping is not obvious. In the pre-transfer training phase, participants face a dot-counting task in which the location of the dots follows a predefined sequence. In the test phase, participants face an auditory SRT task in which the spatial organization of the response locations is either the same as spatial sequence in the training phase, or not. Sequence learning is compared to two control conditions: one with a non-sequential random-dot counting in the training phase, and one with no training phase. Results show that sequential training proactively interferes with later sequence learning, regardless of whether the sequence is the same or different in the two phases. Results argue for the existence of a general sequence processor with limited capacity, and that sequence structures and sequenced elements are integrated into a single sequential representation.     

Is anxiety about health associated with desire to exercise, physical activity, and exercise dependence?

There are significant gaps in the literature regarding the behavioural consequences of health anxiety. Although past research indicates that health anxiety is associated with distinctive maladaptive behaviours, such as reassurance seeking, the relationship between health anxiety and wellness-related behaviours, such as physical activity, has not been adequately examined. Given that health anxiety is associated with excessive attempts to ensure health and avoid illness, health anxiety could be potentially related to extreme physical activity, known as exercise dependence. Using the cognitive behavioural model of health anxiety as a framework, this exploratory study investigated the relationships between health anxiety, exercise desire, physical activity, and exercise dependence.Undergraduate university students (n = 144) completed a battery of online measures. Results indicated that only the perceptual component of health anxiety, namely hypervigilance to somatic symptoms, was related to exercise desire and components of exercise dependence. Implications of the findings are discussed and future research avenues are explored.     

Psychometric Validation of the Temptation and Restraint Inventory in Two Samples of College Drinkers1

Drinking restraint, commonly measured by the Temptation and Restraint Inventory (TRI; Collins & Lapp, 1992), refers to a cycle of temptation to drink alcohol and attempts to control alcohol use that results in excessive consumption. Recent research has examined college drinkers using the TRI, however, it has been validated only in adult samples. This study validated the TRI in two samples of college drinkers, designated as “hazardous” (n = 480) and “harmful” (n = 231) drinkers. Using confirmatory factor analysis, the previously reported higher order two-factor structure was identified in both samples. In addition, multiple regression analyses using derived component scores demonstrated that TRI performance was associated with degree of alcohol dependence in both samples. These data support the use of the TRI in college samples.These data were previously presented in November 2002 at the 36th annual meeting of the Association for the Advancement of Behavior Therapy, Reno, NV     

The relation of modelling and the perception of parental care with adolescent smoking: a cross-sectional study

The smoking of tobacco among adolescents is due to several influential factors, both individual and social. The present study aimed at comparing the effects of different variables on adolescent cigarette smoking, specifically, peer and parent modelling, self-regulatory efficacy, and parental degree of care as perceived by the adolescent. Data were collected by means of a self-report questionnaire administered to a sample of 229 secondary school students aged between 15 and 20 years (mean = 16.69, SD = 1.14). To test the influence of different variables, we performed a binary logistic regression analysis. Results indicated that the father is a key figure in that his care and affection can prevent adolescents from becoming a smoker and his modelling is a risk factor. The significant influence of friends was also confirmed and indicated that peer modelling is a strong predictor of adolescent cigarette smoking. Finally, the results revealed that self-regulatory efficacy is a relevant psychological variable capable of preventing smoking initiation during adolescence.     

Exercise Dependence: Diagnostic and Therapeutic Issues for Patients in Psychotherapy

Health promotion and exercise is recognized as an important ingredient in health maintenance. Within the diagnostic category of obsessive-compulsive disorders has been the increased recognition by clinicians of a phenomena best described as exercise dependence. Reviewed herein is its definition, theoretical framework and a spectrum of factors often associated with exercise. Realizing that exercise dependence as a clinical entity is not yet recognized in either the International Classification of Disorders (ICD-9) or the Diagnostic and Statistical Manual (DSM-IV-R), proposed criteria for its inclusion are offered. Where a pattern of behavior shows the presence of symptoms consistent with exercise dependence, clinical diagnosis should be made to assure that appropriate treatment might be offered to manage the condition and continue to make exercise an important part of a healthy lifestyle. Diagnostic and therapeutic considerations are offered for the contemporary psychotherapist.
