Acute exercise effects on worry,state anxiety,and feelings of energy and fatigue among young women with probable Generalized Anxiety Disorder: A pilot study

BackgroundLittle is known about the acute effects of exercise among individuals with clinical or subclinical Generalized Anxiety Disorder (GAD).PurposeThus, this study examined worry, state anxiety, and feelings of energy and fatigue responses to acute aerobic exercise and quiet rest, and explored potential moderators of response among young adult women with worry scores indicative of GAD.MethodsSeventeen young women with Penn State Worry Questionnaire scores ≥45 (60 ± 8) completed 30-min treadmill running at 65%–85% heart rate reserve (%HRR) and 30-min seated quiet rest in counterbalanced order. Outcomes included worry, state anxiety, and feelings of energy and fatigue. Two condition X two time repeated measures ANOVA examined differences across condition and time. Hedges’ d effect sizes (95%CI) were calculated to quantify and compare the magnitude of change. Independent-samples t-tests explored potential moderators of outcome response.ResultsTotal exercise time was 35.8 ± 3.4min with a mean 30.3 ± 0.16 in-zone minutes (65%-85%HRR); participants exercised at ∼72.9 ± 0.03 %HRR (range 66%–79%). Compared with quiet rest, acute exercise significantly improved worry engagement, state anxiety, and feelings of energy and fatigue (all p ≤ 0.031). Moderate-to-large (d = 0.44 to 1.69) reductions in state anxiety and feelings of fatigue and improvements in feelings of energy were found. Exercise-induced reductions in worry engagement were significantly larger among non-high trait anxious participants. Compared to normal sleepers, quiet rest significantly increased feelings of fatigue among poor sleepers.ConclusionFindings provide support for the positive effects of acute aerobic exercise on worry, state anxiety, and feelings of energy and fatigue among young women with worry indicative of GAD.

Factor solutions of the Social Phobia Scale (SPS) and the Social Interaction Anxiety Scale (SIAS) in a Swedish population

Culturally validated rating scales for social anxiety disorder (SAD) are of significant importance when screening for the disorder, as well as for evaluating treatment efficacy. This study examined construct validity and additional psychometric properties of two commonly used scales, the Social Phobia Scale and the Social Interaction Anxiety Scale, in a clinical SAD population (n?=?180) and in a normal population (n?=?614) in Sweden. Confirmatory factor analyses of previously reported factor solutions were tested but did not reveal acceptable fit. Exploratory factor analyses (EFA) of the joint structure of the scales in the total population yielded a two-factor model (performance anxiety and social interaction anxiety), whereas EFA in the clinical sample revealed a three-factor solution, a social interaction anxiety factor and two performance anxiety factors. The SPS and SIAS showed good to excellent internal consistency, and discriminated well between patients with SAD and a normal population sample. Both scales showed good convergent validity with an established measure of SAD, whereas the discriminant validity of symptoms of social anxiety and depression could not be confirmed. The optimal cut-off score for SPS and SIAS were 18 and 22 points, respectively. It is concluded that the factor structure and the additional psychometric properties of SPS and SIAS support the use of the scales for assessment in a Swedish population.     

儿童早期亲子间情绪谈话的影响因素

作为父母情绪社会化的一种重要途径,亲子间有关情绪的谈话对儿童个性和社会性的发展意义重大。研究发现,包括文化、种族、社会经济地位在内的外部社会环境,儿童的年龄、性别和依恋等特点,以及父母的依恋、养育观念和心理健康状况等因素,都会对父母与儿童之间有关情绪的谈话产生影响。未来亲子间有关情绪的谈话研究应更多考虑儿童长远发展的社会文化适应性视角,加强对非言语信息、亲子间交互回应行为的分析,拓展儿童中期和青春期的探讨,并进一步细化各项研究指标的差异水平、考虑中介因素的作用。     

青少年同伴依恋与问题性手机使用的关系:自我建构对孤独感中介作用的调节

采用同伴依恋问卷、问题性手机使用量表、孤独感问卷以及自我建构量表对624名青少年进行调查,以探讨青少年同伴依恋对问题性手机使用的作用过程及其机制。结果显示,青少年同伴依恋通过孤独感的完全中介作用对问题性手机使用产生影响;依存型建构在孤独感与问题性手机使用之间起调节作用,独立型建构的调节作用不显著。这说明同伴依恋通过孤独感影响青少年的问题性手机使用,依存型建构可促进感到孤独的青少年使用手机。     

大学生依恋与心理弹性——情绪调节与元情绪的多重中介

对982名大学生的依恋、情绪调节策略、元情绪及心理弹性进行测查,考察依恋与心理弹性间关系的内在机制。结构方程模型分析结果显示：（1）依恋、情绪调节与元情绪均能显著预测心理弹性;（2）依恋焦虑通过认知重评和元情绪间接预测心理弹性;（3）依恋回避不但直接负向预测心理弹性,还会通过认知重评和元情绪间接预测心理弹性。本研究结果显示,情绪调节策略和元情绪能够解释依恋与心理弹性间关系的内在机制。     

Stress associated changes in Pavlovian-instrumental transfer in humans

Predictive learning is known to influence instrumental responding for reward. Cues associated with an instrumental outcome can influence performance in two ways: (a) by selectively promoting actions associated with the outcome predicted by the cue (specific transfer), and (b) by increasing motivation and the vigour of instrumental responding (general transfer). To examine these two distinct processes in humans we developed a novel behavioural task in which participants were able to liberate junk-food snacks from a virtual vending machine. Additionally, the relationship between stress and cue-driven reward seeking was examined using participant scores on the Depression Anxiety and Stress Scale (DASS). Reward-paired cues were found to separately bias action selection and influence the rate of responding for rewards. Furthermore, the effects of reward-paired cues on the rate of responding for reward was influenced by increased stress and anxiety. Increased levels of stress and anxiety were associated particularly with changes in cue-driven response vigour; whereas high levels of stress and anxiety were associated with elevated responding above baseline in the presence of a cue associated with a non-rewarding outcome, participants with low levels of anxiety and stress showed appropriate suppression of responding during this cue. These differences in performance between high and low anxiety and stress participants provides initial evidence that, as has been demonstrated in rodents, stress affects the influence of cue-driven response vigour in humans.     

The relationship between attachment, personality and antisocial tendencies in a prison sample: a pilot study

This study examined the role of adult attachment and personality in relation to antisocial tendencies (i.e. convictions for violence and interpersonal problems in romantic relationships) in Norwegian prison inmates (N=92). Attachment styles and personality were measured using self-report questionnaires (RSQ; Griffin & Bartholomew, 1994; and NEO-FFI, Costa & McCrae, 1992a). The prison inmates scored higher on avoidant than on anxious attachment style. While age and agreeableness (negatively associated) emerged as significant predictors of violence, anxious attachment explained most of the variances in aggression in intimate relationships. The study suggests that different types of antisocial tendencies could have different attachment and general personality correlates.     

Transdiagnostic internet treatment for anxiety and depression: a randomised controlled trial

Disorder-specific cognitive behavioural therapy programs delivered over the internet (iCBT) with clinician guidance are effective at treating specific anxiety disorders and depression. The present study examined the efficacy of a transdiagnostic iCBT protocol to treat three anxiety disorders and/or depression within the same program (the Wellbeing Program). Seventy-seven individuals with a principal diagnosis of major depression, generalised anxiety disorder, panic disorder, and/or social phobia were randomly assigned to a Treatment or Waitlist Control group. Treatment consisted of CBT-based online educational lessons and homework assignments, weekly email or telephone contact from a clinical psychologist, access to a moderated online discussion forum, and automated emails. Eighty one percent of Treatment group participants completed all 8 lessons within the 10 week program. Post-treatment data were collected from 34/37 Treatment group and 35/37 Control group participants, and 3-month follow-up data were collected from 32/37 Treatment group participants. Relative to Controls, Treatment group participants reported significantly reduced symptoms of anxiety and depression as measured by the Depression Anxiety and Stress Scales-21 item, Patient Health Questionnaire-9 item, and Generalised Anxiety Disorder-7 item scales, with corresponding between-groups effect sizes (Cohen’s d) at post treatment of.56,.58, and.52, respectively. The clinician spent a mean time of 84.76 min (SD = 50.37) per person over the program. Participants rated the procedure as highly acceptable, and gains were sustained at follow-up. These results provide preliminary support for the efficacy of transdiagnostic iCBT in the treatment of anxiety and depressive disorders.     

Rumination as a transdiagnostic factor in depression and anxiety

The high rate of comorbidity among mental disorders has driven a search for factors associated with the development of multiple types of psychopathology, referred to as transdiagnostic factors. Rumination is involved in the etiology and maintenance of major depression, and recent evidence implicates rumination in the development of anxiety. The extent to which rumination is a transdiagnostic factor that accounts for the co-occurrence of symptoms of depression and anxiety, however, has not previously been examined. We investigated whether rumination explained the concurrent and prospective associations between symptoms of depression and anxiety in two longitudinal studies: one of adolescents (N = 1065) and one of adults (N = 1317). Rumination was a full mediator of the concurrent association between symptoms of depression and anxiety in adolescents (z = 6.7, p < .001) and was a partial mediator of this association in adults (z = 5.6, p < .001). In prospective analyses in the adolescent sample, baseline depressive symptoms predicted increases in anxiety, and rumination fully mediated this association (z = 5.26, p < .001). In adults, baseline depression predicted increases in anxiety and baseline anxiety predicted increases in depression; rumination fully mediated both of these associations (z = 2.35, p = .019 and z = 5.10, p < .001, respectively). These findings highlight the importance of targeting rumination in transdiagnostic treatment approaches for emotional disorders.
