Development of a measure of symptoms in chronic fatigue syndrome: The profile of fatigue-related symptoms(pfrs)

Abstract

Chronic fatigue syndrome (CFS) is a disorder of uncertain aetiology which attracts increasing research interest. This paper describes the development of a multidimensional measure incorporating the diverse symptoms associated with the illness. The Profile of Fatigue-Related Symptoms (PFRS) has four scales: emotional distress, cognitive difficulty, fatigue and somatic symptoms. These showed good convergence with comparison measures, high reliability and high internal consistency. CFS patients had markedly elevated scores compared with a student comparison group, and these scores correlated with indices of illness severity. The PFRS is a short and easily administered measure which, it is suggested, may be used to assess patients in terms of the severity and pattern of their disorder, to relate subjective symptoms to immunological and other findings, to evaluate the effects of treatments, and to compare the symptomatology of CFS with that in other fatiguing illnesses.     

Work Stressors,Depressive Symptoms,and Hazardous Drinking Among Navy Members Across Deployment

Few studies have attempted to examine how changes in work stressors from predeployment to postdeployment and reintegration may be associated with changes in mental health symptoms and hazardous drinking. The present study examined associations between work stressors, depressive symptoms, and hazardous drinking, and whether depressive symptoms mediated the association between work stressors and hazardous alcohol use or vice versa across deployment (predeployment, postdeployment, and 6-month reintegration). Participants were 101 U.S. Navy members (72 men; mean age = 28.34 years; SD = 5.99 years) assigned to an Arleigh Burke-class destroyer that experienced an 8-month deployment after recent wars in the Middle East. They completed measures that assessed work stressors, depressive symptoms, and alcohol use at each time point (i.e., predeployment, postdeployment, and 6-month reintegration). Using a parallel process latent growth modeling approach, we found a significant indirect effect at postdeployment such that an increase in work stressors contributed to increases in hazardous drinking via increases in depressive symptoms. Specifically, increases in work stressors significantly predicted increases in depressive symptoms, which in turn significantly predicted increases in hazardous drinking from pre- to postdeployment. Our findings garner support for affect regulation models and indicate that work stressors and changes in work stressors and depressive symptoms may be key to hazardous alcohol use among U.S. Navy members experiencing high pace of deployment. Taken together, our results help identify targets for alcohol prevention efforts among current military members.     

Relations Among Children's Coping Strategies and Anxiety: The Mediating Role of Coping Efficacy

The current study tests a model that depicts the relationships among coping strategies (active, distraction, avoidance, and support seeking) and anxiety symptoms. SEM is used to test if the relationship between these variables is mediated by coping efficacy. A large sample of Canadian children (N = 506) aged 8 to 11 years (boys = 249, girls = 245, unknown gender = 12) participated in the study. Results showed that coping efficacy is a partial mediator of the relations between active coping strategies and anxiety symptoms, however support was not found for it to be an effective mediator for other coping strategies. This study contributes to the understanding of childhood anxiety by highlighting the importance of the relationship between anxiety and the methods children use to cope with stress and how perceptions of their coping abilities influence this relationship.     

Pervasiveness and correlates of implicit attitudes and stereotypes

http://implicit.harvard.edu/ was created to provide experience with the Implicit Association Test (IAT), a procedure designed to measure social knowledge that may operate outside awareness or control. Significant by-products of the website's existence are large datasets contributed to by the site's many visitors. This article summarises data from more than 2.5 million completed IATs and self-reports across 17 topics obtained between July 2000 and May 2006. In addition to reinforcing several published findings with a heterogeneous sample, the data help to establish that: (a) implicit preferences and stereotypes are pervasive across demographic groups and topics, (b) as with self-report, there is substantial inter-individual variability in implicit attitudes and stereotypes, (c) variations in gender, ethnicity, age, and political orientation predict variation in implicit and explicit measures, and (d) implicit and explicit attitudes and stereotypes are related, but distinct.     

The horserace between distractors and targets: Retrieval-based probe responding depends on distractor–target asynchrony

According to models assuming binding of stimulus and response features, any features can be integrated into a compound (consisting of stimulus and response features) and stored in episodic memory, even features irrelevant to the task. Reencountering any part of such an episode can retrieve the entire episode (or “event file”), including the response. That is, even the repeated presentation of a distractor can retrieve a response given to a target stimulus accompanied by this very distractor. We analysed how distractor-induced retrieval of an event-file competes with the response generation process triggered by the target by varying the stimulus onset asynchrony of targets and distractors. In particular, we used a selection task with prime–probe sequences and asynchronous onset of distractors and targets on the probe. Distractor-induced retrieval was only observed if the probe distractor appeared before or simultaneously with the probe target but not if the probe distractor appeared after probe target onset.     

Talking about daily emotional events: Psychological well-being moderates the intensity–disclosure link

The intensity of distressing events predicts people’s disclosure of those events at between-person and within-person levels. Depression symptoms seem to attenuate the within-person relation, but past research has not taken a multidimensional view of depression as a moderator. The authors tested whether two constructs related to depression-general psychological well-being and life satisfaction-account for depression’s moderating effects. In a daily diary study, college students (N = 116) rated the intensity of the day’s most unpleasant event and their disclosure of the event each day for 14 days. Participants completed measures of disclosure tendencies, depression symptoms, well-being, and life satisfaction prior to the diary portion of the study. Multilevel modeling analyses revealed moderating effects of disclosure tendencies and depression on the within-person intensity–disclosure relation. However, when psychological well-being and life satisfaction were entered, depression was no longer a significant moderator, but well-being was. Psychological well-being therefore determines the expression of individual differences in the disclosure of daily emotional events.     

The role of social support in the acculturation and mental health of unaccompanied minor asylum seekers

There is a lack of knowledge about psychosocial resources that may sustain post‐resettlement psychological adjustment among unaccompanied minor asylum‐seekers. The aim of this study is to investigate the impact of social support from family abroad and friends on acculturation, discrimination, and mental health among these vulnerable children and youth. Questionnaire data were collected from a population‐based multi‐ethnic sample involving 895 unaccompanied minors resettled in municipalities in all regions of the country. They met in groups in their local communities. The informants were on average 18.6 years, and had an average length of stay in Norway of 3.5 years. The findings showed that the participants suffered from high levels of ongoing war related intrusive symptoms and depression. Still, at the same time they engaged in adaptation processes that are normative to youth with immigrant backgrounds, in terms of constructing supportive networks and developing culture competence. In accordance with the main effect hypothesis, social support had direct effects on depression and indirect effects by increasing culture competence that may aid the young refugees in dealing with discrimination. However, there were no effects of social support on symptoms of PTSD. The findings give direction to areas of interventions, beyond dealing with the sequel of the traumas the unaccompanied minors have been exposed to, not only for clinicians, but also social workers and school personnel.     

The Relationship of Adverse Childhood Experiences to PTSD,Depression, Poly-Drug Use and Suicide Attempt in Reservation-Based Native American Adolescents and Young Adults

Adverse childhood experiences (ACEs) are associated with numerous risk behaviors and mental health outcomes among youth. This study examines the relationship between the number of types of exposures to ACEs and risk behaviors and mental health outcomes among reservation‐based Native Americans. In 2011, data were collected from Native American (N = 288; 15–24 years of age) tribal members from a remote plains reservation using an anonymous web‐based questionnaire. We analyzed the relationship between six ACEs, emotional, physical, and sexual abuse, physical and emotional neglect, witness to intimate partner violence, for those <18 years, and included historical loss associated symptoms, and perceived discrimination for those <19 years; and four risk behavior/mental health outcomes: post‐traumatic stress disorder (PTSD) symptoms, depression symptoms, poly‐drug use, and suicide attempt. Seventy‐eight percent of the sample reported at least one ACE and 40 % reported at least two. The cumulative impact of the ACEs were significant (p < .001) for the four outcomes with each additional ACE increasing the odds of suicide attempt (37 %), poly‐drug use (51 %), PTSD symptoms (55 %), and depression symptoms (57 %). To address these findings culturally appropriate childhood and adolescent interventions for reservation‐based populations must be developed, tested and evaluated longitudinally.     

Is hostile attributional bias associated with negative urgency and impulsive behaviors? A social-cognitive conceptualization of impulsivity

The aim of this study was to verify the relevance of social information-processing (SIP) models in the study of impulsivity. 170 undergraduates completed the UPPS Impulsive Behavior Scale relevant to negative urgency, the SIP–AEQ and control measures. The SIP–AEQ consists of eight vignettes featuring a social situation measuring hostile attributional bias (HAB), emotional responses and impulsive behaviors in response to an ambiguous social provocation. Regression analyses showed negative urgency’s unique contribution to indirect HAB after controlling for the effects of aggressiveness, negative emotions and lack of perseverance, another UPPS dimension of impulsivity. Analyses also revealed that indirect HAB mediates the relationship between negative urgency and impulsive behaviors, after controlling for the effects of aggressiveness and negative emotions. Results suggest that SIP models are relevant to study the active social cognitive processes in impulsive behaviors of high-urgency individuals.     

父母亲职压力与儿童对立违抗行为的关系:一项交叉滞后分析

采用亲职压力量表和对立违抗行为表现评估表调查了来自北京、山东和云南三地14所小学有ODD(oppositional defiant disorder)行为表现的301名儿童及其父母。通过为期两年的追踪研究,采用交叉滞后分析探讨了父母亲职压力与儿童的ODD行为之间的关系。结果发现:(1)在第一年和第二年的数据中,父母亲职压力和儿童的ODD行为表现均存在显著正相关;(2)第一年和第二年的父母亲职压力得分显著正相关,同样,两年的儿童ODD行为表现得分也显著正相关;(3)交叉滞后分析发现,对于有ODD行为表现的男孩来说,其父母第一年的亲职压力能预测他们第二年的ODD行为表现,但对于有ODD行为表现的女孩来说,其父母第一年的亲职压力并不能预测她们第二年的ODD行为表现;而不管是男孩,还是女孩,第一年的ODD行为表现都不能预测第二年的父母亲职压力。研究结果揭示出男孩父母的亲职压力可预测男孩的ODD行为表现,而不论是男孩或女孩的ODD行为表现都不能预测其父母亲职压力,说明父母亲职压力可能是男孩ODD行为表现的影响因素。
