A parent-report measure of children's anxiety: psychometric properties and comparison with child-report in a clinic and normal sample

This study examined the psychometric properties of the parent version of the Spence Children's Anxiety Scale (SCAS-P); 484 parents of anxiety disordered children and 261 parents in a normal control group participated in the study. Results of confirmatory factor analysis provided support for six intercorrelated factors, that corresponded with the child self-report as well as with the classification of anxiety disorders by DSM-IV (namely separation anxiety, generalized anxiety, social phobia, panic/agoraphobia, obsessive-compulsive disorder, and fear of physical injuries). A post-hoc model in which generalized anxiety functioned as the higher order factor for the other five factors described the data equally well. The reliability of the subscales was satisfactory to excellent. Evidence was found for both convergent and divergent validity: the measure correlated well with the parent report for internalizing symptoms, and lower with externalizing symptoms. Parent-child agreement ranged from 0.41 to 0.66 in the anxiety-disordered group, and from 0.23 to 0.60 in the control group. The measure differentiated significantly between anxiety-disordered children versus controls, and also between the different anxiety disorders except GAD. The SCAS-P is recommended as a screening instrument for normal children and as a diagnostic instrument in clinical settings. (C) 2003 Elsevier Ltd. All rights reserved.

Using psilocybin to investigate the relationship between attention, working memory, and the serotonin 1A and 2A receptors

Increasing evidence suggests a link between attention, working memory, serotonin (5-HT), and prefrontal cortex activity. In an attempt to tease out the relationship between these elements, this study tested the effects of the hallucinogenic mixed 5-HT1A/2A receptor agonist psilocybin alone and after pretreatment with the 5-HT2A antagonist ketanserin. Eight healthy human volunteers were rested on a multiple-object tracking task and spatial working memory task under the four conditions: placebo, psilocybin (215 mu g/kg), ketanserin (50 mg), and psilocybin and ketanserin. Psilocybin significantly reduced attentional tracking ability, but had no significant effect on spatial working memory, suggesting a functional dissociation between the two tasks. Pretreatment with ketanserin did not attenuate the effect of psilocybin on attentional performance, suggestinga primary involvement of the 5-HT1A receptor in the observed defecit. Based on physiological and pharmacological data,we speculate that this impaired attentional performance may reflect a reduced ability to suppress or ignore distracting stimuli rather than reduced attentional capacity. The clinical relevance of these results is also discussed.

Imaginary relish and exquisite torture: The elaborated intrusion theory of desire

The authors argue that human desire involves conscious cognition that has strong affective connotation and is potentially involved in the determination of appetitive behavior rather than being epiphenomenal to it. Intrusive thoughts about appetitive targets are triggered automatically by external or physiological cues and by cognitive associates. When intrusions elicit significant pleasure or relief, cognitive elaboration usually ensues. Elaboration competes with concurrent cognitive tasks through retrieval of target-related information and its retention in working memory. Sensory images are especially important products of intrusion and elaboration because they simulate the sensory and emotional qualities of target acquisition. Desire images are momentarily rewarding but amplify awareness of somatic and emotional deficits. Effects of desires on behavior are moderated by competing incentives, target availability, and skills. The theory provides a coherent account of existing data and suggests new directions for research and treatment.

Anxiety and social worries in children with Asperger syndrome

Objective: The current study examined anxiety and social worries in a group of children with Asperger syndrome (AS). Method: Sixty-five children with AS were compared with a clinically anxious sample and a normative sample using parent and child reports. Results: Comparisons between clinically anxious children and children with AS showed similar scores on overall anxiety and on six anxiety subscales using child reports. Parent reports revealed higher ratings of overall anxiety and described children with AS experiencing more obsessive-compulsive symptoms and physical injury fears than clinically anxious children. Conclusions: Children with AS without a diagnosis of anxiety, present with more anxiety symptoms than a normal population and with a different profile than a clinically anxious population. Study limitations are identified and considerations for future research presented.

Passion and psychological adjustment: A test of the person-environment fit hypothesis

Passion represents a strong inclination toward an activity that is important, liked, and in which significant time is invested. Although a harmonious passion is well integrated in one’s identity and is emitted willingly, obsessive passion is not well integrated and is emitted out of internal pressure. This study tested for the presence of a Passion × Environment fit interaction with respect to psychological adjustment. Elite hockey players (N = 233) who tried out for a team in a highly competitive league participated in this short-term longitudinal study. As hypothesized, being selected by the highly competitive leagues led to higher psychological adjustment than not being selected by such leagues. Two months later, an interaction revealed that among athletes who were playing in highly competitive leagues, obsessively passionate athletes reported higher psychological adjustment than did harmonious athletes. Conversely, among athletes playing in less competitive leagues, harmonious athletes reported higher psychological adjustment than did obsessive athletes.

The psychosocial impact of an activity holiday for young children with severe food allergy:a longitudinal study

Background Food allergy has been shown to severely affect quality of life (QoL) in children and their families. The Anaphylaxis Campaign UK supports families with allergic children and as part of that support ran an activity holiday for those with food allergy. This study investigated the effectiveness of this activity holiday for reducing anxiety and improving QoL and food allergy management for these children. Methods Measures were taken at baseline, at the start of the activity holiday, at the end of the holiday, at 3 and 6 months follow-up. Children (n = 24) completed a paediatric food allergy–specific QoL questionnaire (PFA-QL), a generic QoL questionnaire (PedsQL™), the Spence Children's Anxiety Scale (SCAS) and the Children's Health Locus of Control (CHLC) scale at all stages of the study. Results There were significant improvements in social QoL, food allergy–specific QoL, total CHLC and internal locus of control scores over time (p > 0.05). There were significant decreases in powerful others locus of control, total anxiety and obsessive compulsive disorder scores (p < 0.05). Greater anxiety significantly correlated with poorer QoL at all time points; no correlations with locus of control were significant at the 3- and 6-month follow-up. Conclusions The activity holiday was of significant benefit to the children who took part, providing support for the need for activity holidays such as this for children with severe food allergy. Ways in which adaptive locus of control and improved quality of life can be facilitated need to be further explored.

What checkers actually check:an eye tracking study of inhibitory control and working memory

Background - Not only is compulsive checking the most common symptom in Obsessive Compulsive Disorder (OCD) with an estimated prevalence of 50–80% in patients, but approximately ~15% of the general population reveal subclinical checking tendencies that impact negatively on their performance in daily activities. Therefore, it is critical to understand how checking affects attention and memory in clinical as well as subclinical checkers. Eye fixations are commonly used as indicators for the distribution of attention but research in OCD has revealed mixed results at best. Methodology/Principal Finding - Here we report atypical eye movement patterns in subclinical checkers during an ecologically valid working memory (WM) manipulation. Our key manipulation was to present an intermediate probe during the delay period of the memory task, explicitly asking for the location of a letter, which, however, had not been part of the encoding set (i.e., misleading participants). Using eye movement measures we now provide evidence that high checkers’ inhibitory impairments for misleading information results in them checking the contents of WM in an atypical manner. Checkers fixate more often and for longer when misleading information is presented than non-checkers. Specifically, checkers spend more time checking stimulus locations as well as locations that had actually been empty during encoding. Conclusions/Significance - We conclude that these atypical eye movement patterns directly reflect internal checking of memory contents and we discuss the implications of our findings for the interpretation of behavioural and neuropsychological data. In addition our results highlight the importance of ecologically valid methodology for revealing the impact of detrimental attention and memory checking on eye movement patterns.

Priming moral self-ambivalence heightens deliberative behaviour in self-ambivalent individuals

Background: Recent work on cognitive-behavioural models of obsessive-compulsive disorder has focused on the roles played by various aspects of self-perception. In particular, moral self-ambivalence has been found to be associated with obsessive-compulsive phenomena. Aims: In this study we used an experimental task to investigate whether artificially priming moral self-ambivalence would increase participants' deliberation on ethical problems, an index that might be analogous to obsessive-compulsive behaviour. Method: Non-clinical participants completed two online tasks designed to prime either moral self-ambivalence, general uncertainty, or neither. All participants then completed a task requiring them to consider solutions to moral dilemmas. We recorded the time participants took to respond to the dilemmas and the length of their responses; we then combined these variables to create a measure of deliberation. Results: Priming moral self-ambivalence led to increases in deliberation, but this was only significant among those participants who scored highly on a baseline measure of moral self-ambivalence. Priming general uncertainty had no significant effect upon deliberation. Conclusions: The results suggest that moral self-ambivalence may play a role in the maintenance of obsessive-compulsive behaviour. We propose that individuals who are morally self-ambivalent might respond to situations in which this ambivalence is made salient by exhibiting behaviour with obsessive-compulsive characteristics. These findings have implications for the incorporation of ideas about self-concept into theories of obsessive-compulsive disorder.

Personality profile of male adolescents with Tourette syndrome:a controlled study

Tourette syndrome is a neurodevelopmental disorder characterized by multiple tics and commonly associated with behavioral problems, especially obsessive-compulsive disorder and attention-deficit hyperactivity disorder (ADHD). The presence of specific personality traits has been documented in adult clinical populations with Tourette syndrome but has been underresearched in younger patients. We assessed the personality profiles of 17 male adolescents with Tourette syndrome and 51 age- and gender-matched healthy controls using the Minnesota Multiphasic Personality Inventory-Adolescent version, along with a standardized psychometric battery. All participants scored within the normal range across all Minnesota Multiphasic Personality Inventory-Adolescent version scales. Patients with Tourette syndrome scored significantly higher than healthy controls on the Obsessiveness Content Scale only (P = .046). Our findings indicate that younger male patients with Tourette syndrome do not report abnormal personality traits and have similar personality profiles to healthy peers, with the exception of obsessionality traits, which are likely to be related to the presence of comorbid obsessive compulsive symptoms rather than tics.

Group cognitive -behavioral therapy for heterogeneous anxiety disorders in children and adolescents: A multiple baseline study

This study investigated the efficacy of Group Cognitive-Behavioral Therapy (GCBT) in the treatment of heterogeneous anxiety disorders in children. A partially nonconcurrent multiple baseline across groups design was used to assess the effects of the treatment on 12 clinically referred children and adolescents between 6 and 16 years of age who met DSM-IV criteria for an anxiety disorder. Targeted diagnoses included Obsessive Compulsive Disorder, Simple Phobia, Separation Anxiety Disorder, Social Phobia, and Generalized Anxiety Disorder, with three of the children also presenting with school refusal behavior. Duration of baseline for each of the three groups varied and ran for one, two, or three weeks. Dependent measures included diagnostic status, child and parent-completed reports, and daily child and parent ratings of child anxiety severity. Results indicated that GCBT was efficacious in reducing anxious symptoms in children and adolescents treated in diagnostically heterogeneous groups, and that gains were generally maintained at 6 and 12 month follow-ups. Findings are discussed in terms of their theoretical and practical implications for the efficient treatment of children and adolescents with anxiety disorders. ^

Personalidade e sua relação com transtornos de ansiedade e de humor: Uma análise da produção científica brasileira na abordagem cognitivo-comportamental

Personality is one of the most controversial and intriguing theme in Psychology. In a general way, it could be understood as a set of rigid patters of feelings, thoughts, and behaviors from an individual. The aim of this investigation was describe how Brazilian researches in Psychology that use cognitive, behavioral, and cognitive-behavioral therapy referential have been approaching the subject Personality in their work. We also intended to determine the frequency of publications on Personality Disorders to compare this data with the bibliographical production on Anxiety and Mood Disorders. Moreover, we tried to describe how the Personality construct - and even Personality Disorders construct - has been addressed in the work on the Anxiety and Mood Disorders chosen for this review. The PePSIC Periódicos Eletrônicos em Psicologia - e SciELO.ORG - Scientific Electronic Library Online - databases were used for research. We investigated 53 journals, including two specific Cognitive Therapies and Behavioral-Cognitive Therapy (TCC) periodicals. Within each journal, we undertook a systematic survey on publications on the themes: Personality, Personality Disorder, Panic Disorder, Social Phobia, Obsessive-Compulsive Disorder (OCD), Generalized Anxiety Disorder, Major Depression, Dysthymia and Bipolar Disorder. A preliminary research has resulted in 218 articles. A second filter has obtained 81 articles in which we the focused on this review. There were found thirty-eight articles on Anxiety Disorders, twenty-five on Mood Disorders and eighteen on Personality Disorders. It was found that 90% of the papers on Anxiety Disorders make no reference to the term Personality or make it in a discrete way. This number rises to 96% to Personality Disorder group. Analyzing the specific journals on TCC we verified that 97% of the articles on Anxiety and Humor disorders do not cite the term Personality or cite but not explore it. This results point to the low rate of studies addressing the Personality and personality disturbs. Then, we can suggest that the difficulty on treating this Axis II disturbs has been worsened by lack of knowledge produced on the subject, either for lack of interest among researchers or because of the methodological obstacles found on this field.

Reward circuitry dysfunction in psychiatric and neurodevelopmental disorders and genetic syndromes: animal models and clinical findings.

This review summarizes evidence of dysregulated reward circuitry function in a range of neurodevelopmental and psychiatric disorders and genetic syndromes. First, the contribution of identifying a core mechanistic process across disparate disorders to disease classification is discussed, followed by a review of the neurobiology of reward circuitry. We next consider preclinical animal models and clinical evidence of reward-pathway dysfunction in a range of disorders, including psychiatric disorders (i.e., substance-use disorders, affective disorders, eating disorders, and obsessive compulsive disorders), neurodevelopmental disorders (i.e., schizophrenia, attention-deficit/hyperactivity disorder, autism spectrum disorders, Tourette's syndrome, conduct disorder/oppositional defiant disorder), and genetic syndromes (i.e., Fragile X syndrome, Prader-Willi syndrome, Williams syndrome, Angelman syndrome, and Rett syndrome). We also provide brief overviews of effective psychopharmacologic agents that have an effect on the dopamine system in these disorders. This review concludes with methodological considerations for future research designed to more clearly probe reward-circuitry dysfunction, with the ultimate goal of improved intervention strategies.

Examining the Relationship Between Passion and Perceptions of Cohesion in Athletes

The purpose of the present study was to examine the relationship of harmonious and obsessive passion to perceptions of task and social cohesion in team sport athletes. Participants were 370 competitive (N=252) and recreational (N=118) athletes ranging from 18- to 28-years-old (Mage=20.20, SD=1.52) from a wide variety of team sports. Participants completed the Passion Scale (Vallerand et al., 2003) and the Group Environment Questionnaire (Carron et al., 1985). A MANOVA revealed that competitive athletes were more passionate and had higher perceptions of cohesion than did recreational athletes. Multiple regression analyses revealed a positive relationship between both harmonious and obsessive passion and both task (ATG-T, GI-T) and social (ATG-S, GI-S) cohesion. Theoretical and practical implications are discussed pertaining to the importance of harmonious and obsessive passion in athletes and perceptions of cohesion in competitive and recreational sport.

Just Need Some Satisfaction: Examining the Relationship between Passion for Exercise and the Basic Psychological Needs

Individuals often pursue activities for which they are passionate about, and this passion is operationalized as being harmonious (an autonomous desireto engage in the activity) or obsessive (a controlled desire to engage in the activity) in nature (Vallerand et al., 2003). With regard to harmonious passion, Vallerand et al. (2003) suggests that it is fostered in environments that nurture innate needs for autonomy, competence, and relatedness. The purpose of the present study was to explore the nature of the passion-basic psychological needs (competence, autonomy, relatedness) relationship. Kinesiology students (N = 917; Mage = 18.54 SD = 1.66) completed the Passion Scale (Vallerand et al., 2003) and the Psychological Need Satisfaction in Exercise Scale (Wilson et al., 2006). Results from the SEM path analysis indicated that harmonious passion was positively related to competence (SPE = .43) and relatedness (SPE = .43) and obsessive passion was negatively related to autonomy (SPE = -.18)(CFI = .90, RMSEA = .07, SRMR = .07). Implications for exercise participation/enjoyment are discussed.

Acceptance of relapse fears in breast cancer patients: effects of an act-based abridged intervention

Objective: Relapse fear is a common psychological scar in cancer survivors. The aim of this study is to assess the effects of an abridged version of Acceptance and Commitment Therapy (ACT) in breast cancer patients.Method: An open trial was developed with 12 non-metastatic breast cancer patients assigned to 2 conditions, ACT and waiting list. Interventions were applied in just one session and focused on the acceptance of relapse fears through a ‘defusion’ exercise. Interference and intensity of fear measured through subjective scales were collected after each intervention and again 3 months later. Distress, hypochondria and ‘anxious preocupation’ were also evaluated through standardized questionnaires.Results: The analysis revealed that ‘defusion’ contributed to decrease the interference of the fear of recurrence, and these changes were maintained three months after intervention in most subjects. 87% of participants showed clinically significant decreases in interference at follow-up sessions whereas no patient in the waiting list showed such changes. Statistical analysis revealed that the changes in interference were significant when comparing pre, post and follow-up treatment, and also when comparing ACT and waiting list groups. Changes in intensity of fear, distress, anxious preoccupation and hypochondria were also observed.Conclusions: Exposure through ‘defusion’ techniques might be considered a useful option for treatment of persistent fears in cancer patients. This study provides evidence for therapies focusing on psychological acceptance in cancer patients through short, simple and feasible therapeutic methods.
