Abstract
Rumination has been suggested to be an important factor maintaining posttraumatic stress disorder (PTSD). Using an analogue design, this study aimed to experimentally test the hypothesis that trauma-related rumination maintains PTSD symptoms. Fifty-one participants were first asked to give a detailed narrative of a negative life event and were then randomly assigned to a rumination or distraction condition. In line with the hypotheses, rumination about the event resulted in the maintenance of negative mood and intrusive memories immediately after the manipulation whereas distraction resulted in symptom reduction. However, this effect was reversed during a subsequent symptom provocation task, in which distraction led to a greater increase in some of the symptoms than rumination. Results are in line with the idea that rumination is involved in the maintenance of PTSD but may suggest a complex relationship between rumination and posttraumatic stress symptoms.

Abstract
Theoretical conceptualizations of generalized anxiety disorder (GAD) continue to undergo scrutiny and refinement. The current paper critiques five contemporary models of GAD: the Avoidance Model of Worry and GAD [Borkovec, T. D. (1994). The nature, functions, and origins of worry. In: G. Davey & F. Tallis (Eds.), Worrying: perspectives on theory assessment and treatment (pp. 5-33). Sussex, England: Wiley & Sons; Borkovec, T. D., Alcaine, O. M., & Behar, E. (2004). Avoidance theory of worry and generalized anxiety disorder. In: R. Heimberg, C. Turk, & D. Mennin (Eds.), Generalized anxiety disorder: advances in research and practice (pp. 77-108).

Applying an emotion regulation framework to integrative approaches to generalized anxiety disorder. Clinical Psychology: Science and Practice, 9, 85-90]; and the Acceptance-based Model of GAD [Roemer, L., & Orsillo, S. M. (2002). Expanding our conceptualization of and treatment for generalized anxiety disorder: integrating mindfulness/acceptance-based approaches with existing cognitive behavioral models. Clinical Psychology: Science and Practice, 9, 54-68]. Evidence in support of each model is critically reviewed, and each model's corresponding evidence-based therapeutic interventions are discussed. Generally speaking, the models share an emphasis on avoidance of internal affective experiences (i.e., thoughts, beliefs, and emotions). The models cluster into three types: cognitive models (i.e., IUM, MCM), emotional/experiential (i.e., EDM, ABM), and an integrated model (AMW). This clustering offers directions for future research and new treatment strategies.

Abstract
OBJECTIVES Rumination has been linked to self-reported sleep quality. However, whether rumination is related to an objective sleep parameter has not been tested. This study examined whether rumination predicts sleep onset latency (SOL) on the night after an acute psychosocial stressor. We hypothesized that those who ruminate (assessed with both trait and stressor-specific measures) would have longer SOL (assessed with objective and subjective methods). METHODS Seventy participants delivered a 5-minute speech in front of an evaluative panel during an afternoon laboratory session. Trait rumination was assessed before the stressor. Stressor-specific rumination was captured with the frequency of task-related thoughts participants experienced during a 10-minute rest period after the stressor. Participants wore actigraphs on their wrists on the night after the laboratory session to measure objective sleep onset latency (SOL-O). Subjective sleep onset latency was estimated by participants on the subsequent morning. RESULTS Consistent with hypotheses, trait and stressor-specific rumination predicted longer SOL-O and subjective sleep onset latency, respectively. In addition, trait and stressor-specific rumination interacted to predict longer SOL-O. SOL-O was longest among those who engaged in more stressor-specific rumination and had greater trait rumination scores. Neither rumination measure was related to sleep duration or wakefulness after sleep onset. CONCLUSIONS The findings from this study are consistent with previous research linking rumination to subjective sleep quality. The results also suggest that post-stressor ruminative thought may predict delayed sleep onset for those with a propensity for rumination.

Abstract
Imagery appears to be associated with higher levels of anxiety than does worry. Borkovec has argued that worry could be a way of avoiding distressing imagery and the associated affect. Thus worry could suppress emotional activation, interfere with emotional processing, and contribute to the maintenance of anxiety. This hypothesis suggests that short and long-term effects of worrying after experiencing a distressing stimulus should differ from the effects of engaging in imagery. In the short term, imagery should maintain anxiety while worry should not do so, or should do so less. In the longer term, worry should be a less successful way of reducing anxiety associated with the stimulus than imagery, and should be followed by a greater number of intrusive cognitions (indicating the relative failure of emotional processing). These predictions were tested by asking subjects to worry, engage in imagery or “settle down” after watching a distressing video. The results were broadly consistent with the hypothesis. Other interpretations are also considered.

Abstract
Intrusive thoughts are variously reported as images, thoughts, doubts, impulses etc. Recent accounts of emotional processing make important distinctions between cognitive activity in verbal form and images. The comparison of verbal intrusions and images was made on archival data about intrusive cognitions from 628 university students. Images and doubts (a verbal form) occurring together were perceived as more difficult to dismiss than either images or doubts alone. In addition, images and doubts together were more frequent, more probable, and required more effort to counter than images alone. Likewise, images and doubts together and doubts alone were more worrisome and more frequently triggered by various stimuli than images alone. These results suggest that cognitive intrusions identified as a mixture of doubts and images are qualitatively different and more troublesome than those identified as either doubts or images. These findings are discussed in terms of current accounts of emotional processing.

Abstract
A number of studies have indicated that the right hemisphere is specialized for (negative) emotions. Some authors have suggested that this specialization stems from the cognitive characteristics of this hemisphere. More specifically, the verbal and analytic approach that characterizes left hemisphere functioning would inhibit emotional reactions, whereas the imaginal and global approach that characterizes right hemisphere functioning would facilitate emotional reactivity. The present study examined whether these two cognitive strategies have, indeed, different effects on emotional responsivity. Subjects were exposed to a series of aversive slides. One group (n = 14) was instructed to process the slides in a verbal/analytic manner. The second group (n = 14) employed an imaginal/global strategy while viewing the slides. The third group (n = 14) was a control group that received no explicit instructions. Self-reported emotions, skin conductance responses, heart rate frequency, and eye blink startles were recorded. There were no differences between the three groups with regard to any of these variables. Thus, no evidence was obtained to support the idea that processing modes (i.e., verbal/analytic versus imaginal/global) have a differential impact on emotional reactivity. The implications for theories about lateralization of emotions and for cognitive therapy are discussed.

Abstract
A new model of worry is presented, differing from previous work in which worry was set within a broader theory of anxiety. It is proposed that threat is initially evaluated in terms of imminence, likelihood, and cost set against perceived self-efficacy; this evaluation can produce worry as a relatively automatic response. Worry serves the functions of alarm, prompt, and preparation; in terms of processes, it leads to an unfocused attentional style, sensitivity to emotional information, and arousal (which produces self-absorption). Threat (and worry) are maintained if there are elevated evidence requirements or inappropriate problem solving. The therapeutic implications of the model are discussed briefly.

Abstract
Few studies have been conducted on psychological disorders other than post-traumatic stress disorder (PTSD) in war survivors. The aim of this study was to examine PTSD, social anxiety disorder (SAD), and major depressive disorder (MDD) and their associations with distress and quality of life in 174 Albanian civilian survivors of the Kosovo War. This included testing of conceptual models suggesting that experiential avoidance might influence associations between anxiety and mood disorders with psychological functioning. Each of the three psychiatric disorders was associated with greater experiential avoidance and psychological distress, and lower quality of life. Being a refugee was associated with a higher likelihood of having SAD and MDD. We found evidence for experiential avoidance as a partial mediator of the respective effects of SAD and PTSD on quality of life; experiential avoidance did not mediate the effects of disorders on global distress. We also found support for a moderation model showing that only war survivors without SAD and low experiential avoidance reported elevated quality of life; people with either SAD or excessive reliance on experiential avoidance reported compromised, low quality of life. This is the third independent study, each using a different methodology, to find empirical support for this moderation model [Kashdan, T. B., & Breen, W. E. (2008). Social anxiety and positive emotions: a prospective examination of a self-regulatory model with tendencies to suppress or express emotions as a moderating variable. Behavior Therapy, 39, 1-12; Kashdan, T. B., & Steger, M. F. (2006). Expanding the topography of social anxiety: an experience sampling assessment of positive emotions and events, and emotion suppression. Psychological Science, 17, 120-128]. Overall, we provided initial evidence for the importance of addressing PTSD, SAD, MDD, and experiential avoidance in primarily civilian war survivors.

Abstract
Worry is thought to involve a strategy of cognitive avoidance, in which internal verbalization acts to suppress threatening emotional imagery. This study tested the hypothesis that worry-prone individuals would exhibit patterns of between-hemisphere communication that reflect cognitive avoidance. Specifically, the hypothesis predicted slower transfer of threatening images from the left to the right hemisphere among worriers. Event-related potential (ERP) measures of interhemispheric transfer time supported this prediction. Left-to-right hemisphere transfer times for angry faces were relatively slower for individuals scoring high in self-reported worry compared with those scoring low, whereas transfer of happy and neutral faces did not differ between groups. These results suggest that altered interhemispheric communication may constitute one mechanism of cognitive avoidance in worry.

Abstract
The present study examined EEG gamma (35-70 Hz) spectral power distributions during worry inductions in participants suffering from generalized anxiety disorder (GAD) and in control participants without a history of psychiatric illness. As hypothesized, the EEG gamma band was useful for differentiating worry from baseline and relaxation. During worry induction, GAD patients showed higher levels of gamma activity than control participants in posterior electrode sites that have been previously associated with negative emotion. Gamma fluctuations in these electrode sites were correlated with subjective emotional experience ratings lending additional support to interpretations of negative affect. Following 14 weeks of psychotherapy, the GAD group reported less negative affect with worry inductions and the corresponding gamma sites that previously differentiated the clinical from control groups changed for the GAD patients in the direction of control participants. These findings suggest converging evidence that patients suffering from GAD experience more negative emotion during worry and that the EEG gamma band is useful for monitoring fluctuations in pathological worry expected to follow successful treatment.

Abstract
The relation between analogue generalized anxiety disorder (GAD) assessed the day before the events of September 11, 2001 (9/11) and long-term outcome was examined in 44 young adults who were directly exposed the following day to the terrorist attacks in New York City. After controlling for high exposure to the attacks, preattack analogue GAD was associated with greater social and work disability, loss of psychosocial resources, anxiety and mood symptoms, and worry, but not symptoms of posttraumatic stress, assessed 12 months after 9/11. Fear and avoidance of emotions assessed 4 months after 9/11 statistically mediated the relation between preattack analogue GAD and social and work disability, loss of psychosocial support, mood and anxiety symptoms, and worry at 12-month follow-up. Avoidance of emotions 4 months after 9/11 also mediated the relation between preattack analogue GAD and posttraumatic stress symptoms 12 months after 9/11.

Abstract
Worrying may be an avoidance behaviour preventing the discomfort of imagining future threats. To study the link between phasic physiological activation and thought contents, we recruited 32 generalized anxiety disorder (GAD) patients and 31 controls and asked them to report whatever was in their mind just prior to whenever they were prompted. Half of 20 prompts were triggered by non-specific skin conductance fluctuations (activating thoughts). Controls judged activating thoughts as being less pleasant. GAD participants judged activating thoughts as more anxiety provoking, less relaxing and less controllable. Not the level of activation but the appraisal of activating thoughts in a catastrophic fashion differentiates GAD patients from controls.

Abstract
Generalized anxiety disorder (GAD) has been conceptualized as being characterized by the experience of intense emotion, limited understanding of the emotional experience, poor ability to adaptively modulate emotions, and an aversive response to emotions [Mennin, D. S., Turk, C. L., Heimberg, R. G., & Carmin, C. N. (2004). Focusing on the regulation of emotion: a new direction for conceptualizing and treating generalized anxiety disorder. In: M. A. Reinecke, & D. A. Clark (Eds.), Cognitive therapy over the lifespan: theory, research and practice (pp. 60-89). New York: Wiley]. In order to test aspects of this model, participants completed daily diaries and a questionnaire measuring emotion regulation strategies. As hypothesized, relative to controls, individuals classified as having GAD reported more intense daily emotional experiences. Contrary to predictions and previous research, those with GAD did not show poor emotion differentiation and used several emotion regulation strategies more often than control participants. The implications for both the emotion dysregulation model and treatment of GAD are discussed.

Abstract
The experience of childhood cancer can be one of the most severe stressors that parents endure. Studies using illness-specific measures of parental stress indicate that moderate-to-severe parenting stress is quite common in the first year of childhood cancer treatment, and as many as 5% to 10% of these parents go on to develop posttraumatic stress disorder. This review of the literature suggested that although parenting stress symptoms may be relatively transitory for most parents dealing with childhood cancer, the impact of these stress symptoms on parent and child functioning is substantive and worthy of therapeutic attention. The stresses entailed in childhood cancer should be viewed as complex and varied across stages of diagnosis and treatment. Factors associated with increased risk of parental posttraumatic stress symptoms include poor social support, adverse experience with invasive procedures, negative parental beliefs about the child's illness and/or associated treatment, and trait anxiety. For those parents with risk factors that might forebode more severe and enduring stress reactions to their children's cancer, therapeutic strategies are proposed to ameliorate their stress and reduce the development and/or maintenance of posttraumatic stress symptoms.

Abstract
The author reviews research showing that repetitive thought (RT) can have constructive or unconstructive consequences. The main unconstructive consequences of RT are (a) depression, (b) anxiety, and (c) difficulties in physical health. The main constructive consequences of RT are (a) recovery from upsetting and traumatic events, (b) adaptive preparation and anticipatory planning, (c) recovery from depression, and (d) uptake of health-promoting behaviors. Several potential principles accounting for these distinct consequences of RT are identified within this review: (a) the valence of thought content, (b) the intrapersonal and situational context in which RT occurs, and (c) the level of construal (abstract vs. concrete processing) adopted during RT. Of the existing models of RT, it is proposed that an elaborated version of the control theory account provides the best theoretical framework to account for its distinct consequences.

Abstract
The definition of generalized anxiety disorder (GAD) has been narrowed in successive editions of DSM by emphasizing intrusive worry and deemphasizing somatic symptoms of hyperarousal. We tried to determine the clinical characteristics of more broadly defined chronically anxious patients, and whether they would show physiological signs of sympathetic activation. A group whose chief complaint was frequent, unpleasant tension over at least the last six weeks for which they desired treatment, was compared with a group who described themselves as calm. Participants were assessed with structured interviews and questionnaires. Finger skin conductance, motor activity, and ambient temperature were measured for 24h. Results show that during waking and in bed at night, runs of continuous minute-by-minute skin conductance level (SCL) declines were skewed towards being shorter in the tense group than in the calm group. In addition, during waking, distributions of minute SCLs were skewed towards higher levels in the tense group, although overall mean SCL did not differ. Thus, the tense group showed a failure to periodically reduce sympathetic tone, presumably a corollary of failure to relax. We conclude that broader GAD criteria include a substantial number of chronically anxious and hyperaroused patients who do not fall within standard criteria. Such patients deserve attention by clinicians and researchers.

Abstract
Cognitive- behavioral therapy (CBT), although effective, has the lowest average effect size for generalized anxiety disorder (GAD), when compared to effect sizes of CBT for other anxiety disorders. Additional basic and applied research suggests that although interpersonal processes and emotional avoidance may be maintaining GAD symptomatology, CBT has not sufficiently addressed interpersonal issues or emotion avoidance. This study aimed to test the feasibility and preliminary efficacy of an integrative psychotherapy, combining CBT with techniques to address interpersonal problems and emotional avoidance. Eighteen participants received 14 sessions of CBT plus interpersonal emotional processing therapy and three participants (for training and feasibility purposes) received 14 sessions of CBT plus supportive listening. Results showed that the integrative therapy significantly decreased GAD symptomatology, with maintenance of gains up to 1 year following treatment. In addition, comparisons with extant literature suggested that the effect size for this new GAD treatment was higher than the average effect size of CBT for GAD. Results also showed clinically significant change in GAD symptomatology and interpersonal problems with continued gains during the 1-year follow-up. Implications of these results are discussed.

Abstract
Like other forms of emotion, anxiety has been theoretically linked to preparation for action. Worry is a type of anticipatory anxiety and the hallmark of generalized anxiety disorder. Research has shown that worry is associated with vigilance to threat cues and increased muscle tension, which may in part be explained by motor facilitation that accompanies preparation for action. This study assessed corticospinal motor responses during worry using transcranial magnetic stimulation (TMS). Participants received TMS during a worry induction, during motor imagery, and during mental arithmetic, while electromyography and force were measured. TMS over the primary motor cortex elicited larger corticospinal motor responses during worry than mental arithmetic and smaller responses than motor imagery of maximum voluntary contraction of targeted muscles. These findings suggest that the association between worry and motor preparation cannot be explained by high cognitive load and provide further support for theoretical accounts emphasizing the role of action preparation in anxiety.

Abstract
Contemporary models of generalized anxiety disorder (GAD) posit that worry functions as an avoidance strategy. During worry, individuals inhibit threat-related imagery in order to minimize autonomic reactivity to phobic topics. This conceptualization of worry suggests a role for the executive system in exerting top-down inhibitory control (IC) over threat processing. We tested the hypothesis that better performance on an IC task would be associated with greater severity of worry and concomitant anxious mood. Forty-three older adults (age 60-77) with GAD completed the Stroop color word task and a battery of self-report symptom measures. Fifteen of the GAD patients were paired with age- and sex-matched non-anxious controls. In the full GAD sample, age-normed t-scores of Stroop performance were positively correlated with measures of worry and trait anxiety, but not anxious arousal or depression. Positive relationships between IC and symptom severity were upheld in the smaller subsample of GAD patients, while in the matched control group, no relationships between Stroop scores and clinical measures were observed. Patients and controls did not differ in Stroop performance. In the context of a disorder-specific tendency to make maladaptive use of executive functions, better IC may be associated with more severe symptomatology.

Abstract
We hypothesized that the reduced concreteness theory of worry (Stöber & Borkovec, 2002) would be applicable to negative recurrent thinking in general, including depressive rumination. To test this prediction, the current study compared the concreteness of problem descriptions of currently depressed (n = 30), recovered depressed (n = 29) and never depressed (n = 30) individuals. Participants provided open-ended descriptions of two current major problems about which they repeatedly dwell. Blind ratings demonstrated reduced concreteness of the problem descriptions and associated perceived consequences reported by the depressed group relative to the recovered depressed and control groups, which did not differ from each other. These findings are consistent with the hypothesis that recurrent thinking in depression involves reduced concreteness, paralleling the findings in GAD.

Abstract
The role of worry in generalized anxiety disorder (GAD) has been posited to serve as an avoidance of emotional experience, and emotion regulation deficits in GAD have been found in several previous studies. It remains unclear whether those with GAD experience more dysregulated emotions during periods of euthymia and positive affect or whether these deficits occur only during periods of worry. Individuals with GAD (with and without co-occurring dysphoria) and non-anxious controls were randomly assigned to receive a worry, neutral, or relaxation induction. Following the induction, all participants viewed a film clip documented to elicit sadness. Intensity of emotions and emotion regulation were examined following the induction period and film clip. The results revealed that, regardless of co-occurring dysphoria, individuals with GAD in the worry condition experienced more intense depressed affect than GAD participants in the other conditions and controls participants. In contrast, presence of worry appeared to have less impact on indices of emotion dysregulation, which were greater in participants with GAD compared to controls, but largely insensitive to contextual effects of worry or of relaxation. Following film viewing, both GAD participants with and without dysphoria displayed poorer understanding, acceptance, and management of emotions than did controls. However, acceptance and management deficits were most pronounced in individuals with both GAD and co-occurring dysphoria. Implications for the role of emotions in conceptualization and treatment of GAD are discussed.

Abstract
Muscle relaxation therapy (MRT) has continued to play an important role in the modern treatment of anxiety disorders. Abbreviations of the original progressive MRT protocol [Jacobson, E. (1938). Progressive relaxation (2nd ed.). Chicago: University of Chicago Press] have been found to be effective in panic disorder (PD) and generalized anxiety disorder (GAD). This review describes the most common MRT techniques, summarizes recent evidence of their effectiveness in treating anxiety, and explains their rationale and physiological basis. We conclude that although GAD and PD patients may exhibit elevated muscle tension and abnormal autonomic and respiratory measures during laboratory baseline assessments, the available evidence does not allow us to conclude that physiological activation decreases over the course of MRT in GAD and PD patients, even when patients report becoming less anxious. Better-designed studies will be required to identify the mechanisms of MRT and to advance clinical practice.

Abstract
Over the past decade, a number of well-controlled studies have supported the validity of a cognitive model of generalized anxiety disorder (GAD) that has four main components: intolerance of uncertainty, positive beliefs about worry, negative problem orientation, and cognitive avoidance. Although these studies have shown that the model components are associated with high levels of worry in nonclinical samples and with a diagnosis of GAD in clinical samples, they have not addressed the question of whether the model components can predict the severity of GAD. Accordingly, the present study sought to determine if the model components are related to diagnostic severity, worry severity, and somatic symptom severity in a sample of 84 patients with a primary diagnosis of GAD. All model components were related to GAD severity, although positive beliefs about worry and cognitive avoidance were only modestly associated with the severity of the disorder. Intolerance of uncertainty and negative problem orientation had more robust relationships with the severity of GAD (and with worry severity, in particular). When participants were divided into Mild, Moderate, and Severe GAD groups, intolerance of uncertainty and negative problem orientation distinguished the Moderate and Severe GAD groups from the Mild GAD group, even when age, gender, and depressive symptoms were statistically controlled. Overall, the results lend further support to the validity of the model and suggest that intolerance of uncertainty and negative problem orientation are related to the severity of GAD, independently of sociodemographic and associated clinical factors. The theoretical and clinical implications of the findings are discussed.

Abstract
The effects of worry and rumination on affective states and mentation type were examined in an unselected undergraduate sample in Study 1 and in a sample of individuals with high trait worry and rumination, high rumination, and low worry/rumination in Study 2. Participants engaged in worry and rumination inductions, counterbalanced in order across participants to assess main and interactive effects of these types of negative thinking. During mentation periods, the thought vs. imaginal nature and the temporal orientation of mentations were assessed 5 times. Following mentation periods, negative and positive affect, relaxation, anxiety, and depression were assessed. Both worry and rumination produced increases in negative affect and decreases in positive affect. Worry tended to generate greater anxiety, and rumination tended to generate greater depression. Interactive effects were also found indicating that worry may lessen the anxiety experienced during subsequent rumination. Moreover, worry lessened the depressing effects of rumination. Worry was associated with significantly greater thought than imagery, compared to rumination. Rumination involved a progression from mentation about the past to mentation about the future over time. Implications for understanding the generation of negative affect and comorbid anxiety and depression are discussed.

Abstract
Research suggests that experiential avoidance may play an important role in generalized anxiety disorder (GAD); see . Expanding our conceptualization of and treatment for generalized anxiety disorder: Integrating mindfulness/acceptance-based approaches with existing cognitive-behavioral models. Clinical Psychology: Science and Practice, 9, 54-68, for a review). Therefore, a treatment that emphasizes experiential acceptance, as well as intentional action, may lead to both reduced symptomatology and improved quality of life and functioning for individuals with this chronic disorder. In an open trial of a newly developed acceptance-based behavior therapy for GAD, 16 treated clients demonstrated significant reductions in clinician-rated severity of GAD and reports of anxiety and depressive symptoms and fear and avoidance of their internal experience, as well as significant improvements in reports of quality of life, at both posttreatment and 3-month follow-up. Directions for future treatment development and research are discussed.

Abstract
This article is a condensation of several chapters from Principles of Therapeutic Change That Work edited by L.G. Castonguay and L.E. Beutler. The authors present the work of M.G. Newman, W.B. Stiles, A. Janeck, and S.R. Woody (2006), who outline an integrative model for effective psychotherapy of anxiety disorders. The authors also summarize, review, and extend several chapters on the current knowledge about therapeutic technique factors (S.R. Woody & T.H. Ollendick, 2006), participant factors (M.G. Newman, P. Crits-Christoph, M.B. Connelly Gibbons, & T.M. Erickson, 2006), and relationship factors (W.B. Stiles & B.E. Wolfe, 2006), which are related to anxiety disorder treatment outcome. The authors then place these factors and their practice implications within a common framework. Their integration is based on (a) the concept of appropriate responsiveness, and (b) a distinction between actions and achievements.

Abstract
Generalized anxiety disorder is a highly debilitating psychologic disorder associated with cognitive, affective, behavioral and physiologic forms of rigidity and dysfunction. Chronic and uncontrollable worry, a future-oriented and highly negative form of verbal thought, is its hallmark symptom. Cognitive behavioral therapy, the most well-established psychologic treatment for generalized anxiety disorder, entails techniques designed to target and reduce dysfunction in each of these mutually interrelating domains. This review serves as an introduction to cognitive behavioral therapy for generalized anxiety disorder, including conceptualization, treatment methods and evidence for efficacy. Future directions for augmenting treatment efficacy are also discussed.

Abstract
To study the psychophysiological correlates of worrying, the authors recorded heart rate, respiratory sinus arrhythmia (RSA), skin conductance level, and alpha electroencephalographic asymmetry in healthy males during baseline, relaxation, worry induction, and anticipation of an impromptu speech task. Compared with baseline, relaxation, and anticipation, worrying was associated with greater heart rate and lower RSA. Worrying was further characterized by higher skin conductance levels compared with baseline but lower levels than during anticipation. Finally, worrying was associated with relatively greater left frontal activity compared with anticipation. Trait public speaking anxiety was positively correlated with left frontal activity during worrying. These results support the notion that worrying is a unique emotional state that is different from fearful anticipation.

This study examined the association between worry and fearful responding to a 3-min voluntary hyperventilation procedure. Participants were 160 adolescents (71 females) between the ages of 12 and 17 years (M=14.92 years). After accounting for the significant effects of state anxiety and anxiety sensitivity, results indicated that pre-challenge levels of worry indexed by the Penn State Worry Questionnaire-Child Version predicted post-challenge anxiety and intensity of panic symptoms. Results are discussed in terms of the role of worry in relation to panic-relevant emotional vulnerability among youth.

Abstract
Several studies suggest that cognitive tasks attenuate activation of the limbic system by emotional stimuli. We investigated the possibility that worry would similarly inhibit the limbic system by examining its effects on regional cerebral blood flow (rCBF). Ten nonanxious volunteers underwent four scans within one session, using positron emission tomography (PET) with H(2)(15)O as tracer. The first two scans recorded emotionally neutral thinking induced after listening to tapes describing neutral statements. Preceding the third and fourth scans, subjects listened to the self-recorded tape describing their individual worries, were instructed to continue to worry, and were scanned 5 min later. Subjects rated themselves as more anxious during the worry scans but showed no significant heart interbeat or skin conductance changes. During worry, rCBF increases were found bilaterally in the medial fronto-orbital gyri and the right thalamus; rCBF decreases were found bilaterally in the hippocampi and amygdalae, in the right insula, the left and right inferior, middle and superior temporal gyri and the occipito-temporal gyri, the right inferior occipital gyrus and the left supramarginal gyrus. Activity of the left orbito-frontal gyrus was negatively correlated with activity of the amygdalae. The results support the hypothesis that worry-induced prefrontal activity suppresses affect-related subcortical regions.

Abstract
Although separate lines of behaviorally oriented pain research have drawn attention to the importance of pain catastrophizing and trait worry, little is known about how they work together to influence aspects of chronic pain. Integrating pain research with the broader anxiety, cognitive science, and learning literature, we hypothesized that the process (vs. content) of worry influences pain through catastrophizing. One hundred and eighty-six consecutive patients diagnosed (Rome II) with irritable bowel syndrome completed measures of three dimensions of pain (sensory pain, affective pain, long-term suffering), pain intensity, trait anxiety, worry, catastrophizing, and somatization during baseline assessment of an NIH-funded clinical trial of two psychological treatments. Worry was most strongly associated with the emotionally unpleasant aspects of pain, particularly suffering. Multivariate mediational analyses showed that catastrophizing mediated the link between worry and suffering. Worry, catastrophizing and control variables accounted for 46% of the variance in suffering. Chronic pain patients who worry excessively engage in more catastrophic thinking and through this cognitive process experience more intensely the suffering component of pain. Data are consistent with the notion that worry functions as an "experiential avoidance" strategy for aversive features of pain. Findings are discussed with respect to their relevance to behavioral models for understanding and treating anxiety-related chronic pain disorders.

Abstract
Although it has been fairly well established that symptoms of anxiety are often present in patients with irritable bowel syndrome (IBS), less is known about the role of worry and intolerance of uncertainty in this population. This study investigates the relations among these variables in a sample of treatment-seeking IBS patients. Although the results are preliminary, worry does seem to predict gastrointestinal symptom severity and, when combined with a measure of current anxiety, accounts for almost 30% of the variance. Intolerance of uncertainty differentiated diarrhea-predominant IBS patients from constipation-predominant IBS patients. Earlier research has taken a psychiatric perspective on anxiety in IBS patients—the current study may provide some support for shifting our focus to the cognitive biases that may be operating in IBS patients, regardless of the presence of an anxiety disorder. Implications for a cognitive therapy approach to IBS treatment are discussed.

Abstract
Negative problem orientation, a dysfunctional set of attitudes related to problem-solving ability, has been implicated as a process variable in several psychological disorders, notably depression and generalized anxiety disorder (GAD). The goal of the present study was two-fold: (1) to further examine the construct validity of a new measure of negative problem orientation, the negative problem orientation questionnaire (NPOQ), through its relationship to conceptually similar variables, and (2) to investigate the specificity of negative problem orientation to worry, the cardinal feature of GAD, compared to depression. The sample consisted of 148 university students who completed six questionnaires, the NPOQ and measures of worry, depression, pessimism, self-mastery, and neuroticism. Multiple hierarchical regressions revealed that when entered in the last step following demographic information and personality variables (pessimism, self-mastery, and neuroticism), the NPOQ accounted for 5.6% of the variance in worry scores compared to 1.6% of the variance in depression scores. It was concluded that the NPOQ shows evidence of construct validity, and that the process variable of negative problem orientation appears to have greater specificity to worry than depression. Implications for the understanding of worry and GAD are discussed.

Abstract
The current study investigated whether the immediacy and concreteness of fear stimuli play an important role in the effects of trait worry on physiological response to fear. One hundred and eight participants were exposed to one of three fear-provoking stimuli: an actual spider (immediate and concrete), an opaque box which they were told contained a spider (immediate but abstract), or a recorded script (distant and abstract). Participants were yoked by levels of worry and gender. Heart rate, vagal tone, and skin conductance were recorded. The combination of high worry and an actual spider caused the largest decrease in vagal tone, but both the actual spider and opaque box increased skin conductance regardless of worry level. The results suggest that factors, such as the type of fear stimulus and the type of physiological measures used, are vital in understanding the reasons for and the limits of fear activation.

Abstract
This study tested the hypothesis that interhemispheric communication about emotional stimuli is influenced by situational factors that alter emotional relevance. Under evaluative or nonevaluative conditions, participants matched angry and happy faces within a single visual field or across opposite visual fields. An overall across-field advantage (AFA) reflected the benefit of sharing information between the hemispheres. The AFA was greater for angry than for happy faces in the evaluation condition but did not differ for angry and happy faces in the no-evaluation condition. Examination of individual differences indicated that high trait evaluation levels of worry were associated with poorer interhemispheric communication of angry faces, supporting a threat-avoidance conception of worry. Thus, both situational factors and individual differences affected interhemispheric communication about emotional faces.

Abstract
Social phobia (social anxiety disorder) was officially recognized as a distinct clinical entity only with the publication of the DSM-III in 1980. Research on the psychopathology of this disorder has revealed a great degree of heterogeneity in its symptomatology. In order to acknowledge this heterogeneity, later versions of the nosological system introduced the generalized subtype of social phobia to describe individuals who fear most or all social situations. The empirical literature on the differences between the diagnostic subtypes has yielded inconsistent findings. Based on the recent emotion literature and concepts from evolutionary psychology, we discuss fearfulness, anxiousness, shyness, self-consciousness, submissiveness, and anger as dimensions of social phobia. The empirical evidence for this classification system and its relationship to the diagnostic subtypes will be discussed.

Abstract
Anxious people often show a particular attentional focus towards potentially threatening stimuli. Like any other emotion, anxiety goes along with physiological reactions, which may be more or less noticeable, and may impair behavior and physical wellness. In view of the psychophysiological reactions related with anxiety and anxiety disorders, it seems important to examine potential correlations between psychophysiological activity and the phenomena of hypervigilance. In fact, selective psychophysiological activation has repeatedly been found as a reaction to pathology-specific threatening stimuli in patients with anxiety disorders, whereas their psychophysiological responses appeared often to be blunted when they were submitted to neutral stimuli.
