These British Association for Psychopharmacology guidelines cover the range and aims of treatment for anxiety disorders. They are based explicitly on the available evidence and are presented as recommendations to aid clinical decision making in primary and secondary medical care. They may also serve as a source of information for patients and their carers. The recommendations are presented together with a more detailed review of the available evidence. A consensus meeting involving experts in anxiety disorders reviewed the main subject areas and considered the strength of evidence and its clinical implications. The guidelines were constructed after extensive feedback from participants and interested parties. The strength of supporting evidence for recommendations was rated. The guidelines cover the diagnosis of anxiety disorders and key steps in clinical management, including acute treatment, relapse prevention and approaches for patients who do not respond to first-line treatments.

The present study examined the ability of a Virtual Reality (VR) public speaking task to elicit physiological arousal in adults with SAD (n=25) and Controls (n=25). A behavioral assessment paradigm was employed to address three study objectives: (a) to determine whether the VR task can elicit significant increases in physiological response over baseline resting conditions (b) to determine if individuals with SAD have a greater increase from baseline levels of physiological and self-reported arousal during the in vivo speech task as opposed to the VR speech task and (c) to determine whether individuals with SAD experience greater changes in physiological and selfreported arousal during each speech task compared to controls. Results demonstrated that the VR task was able to elicit significant increases in heart rate, skin conductance, and respiratory sinus arrhythmia, but did not elicit as much physiological or self-reported arousal as the in vivo speech task. In addition, no differences were found between groups. Clinical implications of these findings are discussed

Learner absenteeism is one of the major precursors to poor academic performance. If learners miss school, they do not learn and ultimately they fail or drop-out. Notwithstanding, this problem does not receive the attention it deserves. A literature study, which reviewed research findings concerning absenteeism in South Africa and selected countries, provided a framework for the ensuing empirical inquiry. A qualitative study using in-depth interviews, focus group interviews, document review and observation as data gathering techniques focused on two selected primary schools with a high rate of learner absenteeism in the Acornhoek area of Mpumalanga, South Africa. Participants were purposefully selected as information rich candidates: absentee learners, parents of absentee learners, teachers and school principals. Learner absenteeism negatively impacts effective professional practice, that is, teaching and learning. The study concludes with recommendations to prevent learner absenteeism in order to improve teaching and learning in South African primary schools. / Curriculum and Instructional Studies / M. Ed.

While previous studies successfully identified the core neural substrates of the animal subtype of specific phobia, only few and inconsistent research is available for dental phobia. These findings might partly relate to the fact that, typically, visual stimuli were employed. The current study aimed to investigate the influence of stimulus modality on neural fear processing in dental phobia. Thirteen dental phobics (DP) and thirteen healthy controls (HC) attended a block-design functional magnetic resonance imaging (fMRI) symptom provocation paradigm encompassing both visual and auditory stimuli. Drill sounds and matched neutral sinus tones served as auditory stimuli and dentist scenes and matched neutral videos as visual stimuli. Group comparisons showed increased activation in the insula, anterior cingulate cortex, orbitofrontal cortex, and thalamus in DP compared to HC during auditory but not visual stimulation. On the contrary, no differential autonomic reactions were observed in DP. Present results are largely comparable to brain areas identified in animal phobia, but also point towards a potential downregulation of autonomic outflow by neural fear circuits in this disorder. Findings enlarge our knowledge about neural correlates of dental phobia and may help to understand the neural underpinnings of the clinical and physiological characteristics of the disorder.

As interações entre o sistema nervoso central e os sistemas imune e endócrino são o objeto de estudo da psiconeuroimunologia. Protocolos de indução de estresse têm sido amplamente utilizados como métodos confiáveis de investigação da relação entre transtornos psiquiátricos, aspectos psicológicos, traços de personalidade, ansiedade e a resposta imune. O procedimento de simulação de falar em público (SFP) é um protocolo experimental validado que reconhecidamente é capaz de ativar o eixo hipotálamo-hipófise-adrenal (HPA) e produzir respostas de estresse em sujeitos humanos. Esse método foi utilizado para: 1) Comparar a reatividade imunológica de indivíduos com diagnóstico de fobia social com a de indivíduos sem qualquer diagnóstico psiquiátrico; 2) Investigar se ocorrem alterações imunes subseqüentes à exposição a um estressor agudo induzido em laboratório e 3) identificar e correlacionar parâmetros imunológicos com traços de personalidade, humor, níveis de ansiedade e medidas fisiológicas. Os traços de personalidade foram investigados por meio dos seguintes instrumentos: Inventário de Temperamento e Caráter (TCI), Escala de Afeto Positivo e Negativo (PANAS), Inventário de Ansiedade Traço (IDATE-T), Inventário de Depressão de Beck (BDI), Inventário de Estratégias de ?Coping? de Folkman e Lazarus e Adaptação da Escala de Percepção de Estresse (PSS). Os sintomas de ansiedade foram avaliados por meio da Escala Analógica Visual de Humor (VAMS), da Escala de Sintomas Somáticos (ESS) e do IDATE-Estado. As variáveis psicofisiológicas avaliadas foram pressão arterial sistólica (PAS), diastólica (PAD), batimentos cardíacos (BPM), resposta galvânica da pele (GSR) e temperatura. Os níveis plasmáticos de catecolaminas (adrenalina, noradrenalina e dopamina) e hormônios do eixo HPA (cortisol e ACTH) também foram dosados. Realizou-se a contagem de células imunes polimorfonucleares e mononucleares no sangue periférico e mediu-se a atividade citotóxica de células NK e neutrófilos. Dosou-se proteínas de fase aguda e imunoglobulinas (A, D, G, M e E) a produção de citocinas no sangue por ELISA e RT-PCR. Os dados foram submetidos a análises de variância para dados com medidas repetidas testando efeitos de grupo, sexo, momento experimental e interações. As correlações entre as variáveis foram testadas por regressões múltiplas e coeficientes de correlação de Pearson. Os resultados apontam que o SFP foi eficiente para induzir estresse e produzir alterações detectáveis em diversos dos parâmetros investigados. As diferenças entre fóbicos sociais e controles são significativas para traços de personalidade e atuam ao longo do tempo para as medidas psicofisiológicas. Alterações imunes e hormonais estiveram mais frequentemente associadas ao gênero do que ao grupo experimental, e afetaram mais homens. Além disso, as alterações imunes foram de pequena magnitude afetando componentes inespecíficos da resposta imune. Conjuntamente, os resultados apontam uma relativa ativação do eixo HPA em fóbicos mas que não corresponde a alterações imunes de mesma magnitude. Mais estudos com uma amostra maior e a investigação de outros parâmetros são necessários para compreender melhor como a fobia social afeta o sistema imune de homens e mulheres e investigar se as alterações podem aumentar a susceptibilidade a doenças nesse grupo de sujeitos. Uma vez que essa interação seja melhor compreendida poderá subsidiar estratégias mais adequadas para abordar e elaborar estratégias de prevenção e intervenção capazes de promover comportamentos saudáveis. / Interactions among the nervous, immune and endocrine systems are the object of study of Psychoneuroimmunology. Stress protocols have been broadly used as reliable means to investigate the relationship among psychiatric disorders, psychological aspects, personality traits, anxiety and immune response has been studied using these interactions. The Simulated Public Speaking (SPS) is a validated experimental procedure known to activate the Hypothalamus-Pituitary-Adrenal (HPA) axis and produce stress responses in human subjects. This method was used to: 1) compare the immune reactions of individuals with a diagnosis of social phobia to that of individuals without any psychiatric diagnosis; 2) investigate if immune alterations occur subsequent to the exposure to an acute laboratory induced stressor; 3) identify and correlate immune parameters with personality traits, mood, anxiety levels and physiologic measures. Personality traits were investigated with Cloninger?s Temperament and Character?s Inventory (TCI), Positive and Negative Affects Scale (PANAS), State-Trait Anxiety Scale (STAI?T), Beck?s Depression Inventory (BDI), Lazarus?s Coping Strategies Inventory, Perceived Stress Scale (PSS). Anxiety symptoms were investigated along the procedure with the Bodily Symptoms Scale (ESS), STAI-E and the Visual Analogue Mood Scale (VAMS). Psychophysiologic variables assessed were Systolic (PAS) and Diastolic (PAD) Blood Pressure, Heart Rate (BPM), Galvanic Skin Response (GSR) and temperature. Plasmatic circulating levels of cathecolamines (Adrenaline, Noradrenaline and Dopamine) and HPA axis hormones (Cortisol, ACTH) were assessed. Peripheral blood cell population counts were obtained for polymorphonuclear (PMN) and mononuclear cells. Cytotoxic activity of neutrophils and NK cells was assessed, as well as cytokine production by ELISA and RT-PCR. Acute phase proteins and immunoglobulins (A, D, G, M, and E) were dosed on peripheral blood. Data was submitted to variance analysis for data with repeated measures testing effects of group, sex, experimental moment and interactions on variables. Correlations among variables were tested by multiple regressions and Pearson?s correlation deltas. The results show SPS was efficient in inducing stress and produce detectable alterations in several of the parameters investigated. Differences between social phobics and controls are significant for personality traits and, along time for psychophysiologic measures. Hormonal and immune alterations were more often associated to gender rather than to the group subjects belonged to, with men being more susceptible to the procedure. Also, immune changes were of small magnitude, usually affecting inespecific components of the response. Together, the results point to a relatively higher activation of the HPA-axis in social phobics, but one that does not correspond to immune responses of the same magnitude. Further studies with a larger sample and investigation of other parameters are necessary to better understand how social phobia affects the immune system of men and women and to investigate if the alterations can increase susceptibility to diseases in this group of individuals. Once this interaction is better understood it may provide the basis for an improved design to approach and elaborate prevention/intervention strategies and promote healthy behaviours.

To study of cognitive fear networks and associations, indirect experimental paradigms like the Implicit Association Test (IAT, Greenwald et al., 1998) or the Extrinsic Affective Simon Task (EAST, De Houwer, 2003) may be helpful, as they promise to assess the structure of specific associations using a performance based approach without having to ask the participant for a verbal report. Three studies investigated the usefulness and characteristics of IAT and EAST. The aim of the first study was to measure fear associations towards spiders among spider phobic and non-phobic participants as well as in a group of spider enthusiasts. Results indicate that the IAT paradigm is sensitive to the strength of fear relevant associations and able to predict anxious behavior beyond the predictions of direct measures such as questionnaires. The second study focused on some of the mechanisms that underlie IAT effects. With a newly developed masked IAT, these experiments investigated the influences of individual stimuli and superordinate categories on IAT performance. Besides theoretical implications, the results also provide practical, relevant applications for the use of IAT experiments. A third study applied the EAST to investigate how different context conditions lead to differential activation of cognitive schemata in fear of spiders. One can conclude that the impact of automatic threat associations depends on the activated context, and that the EAST is suitable for the assessment of fear associations and their current activation level. This dissertation leads to the conclusion that the performance based methodology of the IAT and EAST is a useful and practical approach to reflect fear associations in phobia indirectly. At this point, the use of indirect measures is still at its beginning, and requires intensive methodological and theoretical efforts. These paradigms, however, may become useful for possible implications in psychopathology and other fields of psychology.

BACKGROUND.One group of theories aiming at providing a framework explaining the etiology, maintenance and phenomenology of anxiety disorders is classified as cognitive models of anxiety. These approaches assume that distortions in specific levels of information processing are relevant for the onset and maintenance of the disorder. A detailed knowledge about the nature of these distortions would have important implications for the therapy of anxiety, as the implementation of confrontative or cognitive elements precisely fitting the distortions might enhance efficacy. Still, these models and related empirical evidence provide conflicting assumptions about the nature of disorder-linked processing distortions. Many cognitive models of anxiety (e.g., Fox, Russo, & Dutton, 2002; Mathews & Mackintosh, 1998; Williams, Watts, MacLeod, & Mathews, 1997) postulate that anxiety-linked biases of attention imply hypervigilance to threat and distractibility from other stimuli in the presence of feared materials. This is convincingly confirmed by various experimentalclinical studies assessing attention for threat in anxious participants compared to non-anxious controls (for a review, seeMathews &MacLeod, 2005). In contrast, assumptions concerning anxiety-linked biased memory for threat are less convincing; based on the shared tendency for avoidance of deeper elaboration in anxiety disorders, some models predict memory biases only for implicit memory tasks (Williams et al., 1997) or even disclaim the relevance of memory in anxiety at all (e.g., Mogg, Bradley, Miles, & Dixon, 2004). Other theories restrict the possibility of measuring disorder-specific memory biases to tasks that require merely perceptual encoding of the materials instead of verbal-conceptual memory (e.g., Fox et al., 2002; Mathews &Mackintosh, 1998). On the one hand, none of these models has integrated all the inconsistencies in empirical data on the topic. On the other hand, the numerous empirical studies on memory in anxiety that have been conducted with varying materials, anxiety disorders, encoding and retrieval conditions do not allow final conclusions about the prerequisites for finding memory biases (for a review, see MacLeod & Mathews, 2004). A more detailed investigation of the complete spectrum of memory for threat utilizing carefully controlled variations of depth of encoding and materials is needed. In view of these inconsistencies, it is all the more surprising that one important part of this spectrum has so far remained completely uninvestigated: visual working memory (VWM). No study has ever differentially addressed VWM for threat in anxious vs. nonanxious participants and none of the cognitive models of anxiety provides any predictions concerning this stage of information processing. Research on cognitive biases in anxiety has thus far only addressed the two extremes of the processing continuum: attention and longer-term memory. In between, a gap remains, the bridging of which might bring us closer to defining the prerequisites of memory biases in anxiety. As empirical research has provided substantial and coherent knowledge concerning attention in anxiety, and as attention and VWM are so closely linked (see, for instance, Cowan, 1995), the thorough investigation of VWM may provide important clues for models of anxiety. Is anxiety related to VWM biases favoring the processing of threatening information, or does the avoidance presumed by cognitive models of anxiety already begin at this stage? RESEARCH AIMS. To investigate the relevance of biased VWM in anxiety, the present research focused in eight experiments on the following main research questions: (1) Is threat preferably stored in VWM in anxious individuals? (2) Does threat preference occur at the cost of the storage of other items, or is extra storage capacity provided? (3) Would the appearance of threat interrupt ongoing encoding of non-threatening items? (4) Does prioritized encoding of threat in anxiety occur strategically or automatically? (5) Are disorder-specific VWM biases also materials-specific? (6) Are VWM biases in anxiety modifiable through cognitive-behavioral therapy? METHODS. In Experiments 1-4, a spatial-sequential cueing paradigm was used. A subset of real-object display items was successively cued on each trial by a sudden change of the picture background for 150 ms each. After the cueing, one of the display pictures was hidden and probed for a memory test. On most trials, a cued item was tested, and memory accuracy was determined depending on the item’s position within the cue string and depending on its valence. In some cases, memory for an uncued item was tested. Experiment 1 and 2 were directed at discovering whether spider fearfuls and non-anxious controls would differ with respect to the accuracy in memorizing cued spiders and uncued spiders and, thus, reveal disorder-specific biases of VWM. In addition, the question whether the presence of a spider image is related to costs for the memorization of other images was tested. Experiment 3 addressed whether any disorder-specific VWM biases found earlier were specific to the feared spiders. Therefore, the critical stimuli here were a snake and a spider. Participants were spider fearfuls and non-anxious controls, both without snake anxiety. In Experiment 4, it was tested whether disorder-specific biases found in Experiment 1 and 2 were modifiable through cognitive-behavioral treatment. The critical stimulus was a spider image. Spider fearfuls were tested three times. Half of them received a cognitive-behavioral intervention after the first test, the other half only after the second test. In two additional experiments, VWM was assessed with a change-detection paradigm. The main aim was to clarify whether disorder-specific effects found in the previous experiments were associated with automatic or with strategic selective encoding of threatening materials, and whether any group differences in spider change detection were materials-specific to spiders, but not to snakes. In Experiment 5, several images were presented simultaneously in a study display for either 100 or 500 milliseconds. After a short interruption, a test display was presented including either the same items as the first one or one changed item. Participants’ accuracy in determining whether displays were the same or different was measured depending on the valence of the changed item, set size, and presentation time of the display. There were trials with and without spiders. If a change was made, it could involve either a non-spider or a spider item. Of specific interest was the condition in which a spider image was presented initially, but not in the test phase, as noticing this specific change would require storage of that image in VWM. Would group differences be particularly pronounced in the shorter encoding condition suggesting automatic encoding of threat, or would they occur in the longer encoding condition, suggesting strategic encoding of spiders? In Experiment 6, change detection accuracy for spiders vs. snakes was tested. The participants in both experiments were spider fearfuls vs. controls, but those of Experiment 6 were additionally required to lack snake anxiety. Moreover, a temporal VWM paradigm - an attentional blink task - was applied to assess whether a biased encoding of spider images in spider fearfuls would occur at the expense of non-threatening items undergoing concurrent processing, and whether this effect was specific to spiders, but not to snakes. Series of real-object pictures were presented at rates of 80 ms at the display center. The observer’s task was to identify and report the two target pictures indicated by a brighter background. In Experiment 7, the first target always depicted a neutral item. The valence of the second target was varied - either negative depicting a spider, positive, or neutral. Participants varied with respect to their spider anxiety. In Experiment 8, spider fearfuls and non-anxious controls, both without snake anxiety, were tested. The experiment was nearly the same as the previous one, but two negative target types were tested: disorder-relevant spiders and negative but not feared snakes. Of specific interest was whether the appearance of a threatening target would reduce the report probability of the earlier attended target, indicating the interruption of its VWM encoding in favor of the threat item. RESULTS. (1) Both anxious and non-anxious controls, showed VWM advantages for negative materials such as spider or snake images. (2) In addition, there were disorderspecific VWM biases: some effects were larger in spider fearfuls than in non-anxious controls and some effects occurred exclusively in spider fearfuls. (3) Group differences and, thus, disorder-specificity were particularly pronounced under competitive circumstances, that is, under the condition of numerous stimuli competing for processing resources: when only little orientation time was allowed, when only little time was provided for selecting and encoding items from a crowd, and when VWMfor the critical item required reflexive instead of voluntary attention. (4) Pronounced memory for task-relevant, voluntarily attended spiders was related to difficulties in disengaging attention from these items in the fearful group, reflected in reduced memory accuracy for the item following it. (5) Disorder-specific VWM biases seem to be based on attentional biases to threatening materials resulting in a very quick, automatic memory consolidation. However, this preferential encoding was not at the cost of neutral materials currently undergoing encoding processes. (6) All disorder-specific VWM biases occured only with fear-related materials, not with other negative materials. (7) Automatic and highly disorder-specific fear-related VWM biases – but not strategic VWM biases occuring in both groups - were modifiable through cognitive-behavioral intervention. CONCLUSIONS. This work provides additional information about informationprocessing distortions related to specific anxiety. With the experimental investigation of biased VWM, this work has been performed to fill a gap within research on cognitive biases in anxiety. Moreover, this dissertation contributes to cognitive theories of anxiety by proposing several recommendations for refinements of current theoretical approaches. Most important, it was suggested to extend existing models by a more detailed consideration of attention and memory. In view of numerous previous empirical studies on the topic and the conclusions of this dissertation, a differentiation of the attentional engagement and disengagement component appears inevitable. Even more important, in view of the data presented here predictions concerning VWM for threatening materials need to be taken into account. In addition, suggestions are provided for the differential consideration of biases occuring from prepotent threat value of negative stimuli vs. individual threat value. A proposal for a cognitive model of anxiety extended by all these aspects is provided to serve as an invitation of further research in the investigation of the nature of memory biases in anxiety disorders.

This descriptive survey was carried out to gather information that could be used to assist in the development of an HIV/AIDS educational program as a way to promote adolescents' health and prevent diseases in the United Arab Emirates. The study examines the knowledge, attitudes, beliefs and sources of information of high school students in Sharjah city regarding HIV/AIDS. Anonymous questionnaire with five sections: demographics, HIV/AIDS knowledge, sources of information, attitudes and beliefs was administered to 12th grade high school students from four schools in Sharjah. Analysis of findings showed that 87 percent of students knew that AIDS affects the body's immune system and 68 .5 percent knew that it is not inherited .The majority of students were aware of relationship between drug abuse and HIV/AIDS. However, students lacked information in some areas as HIV/AIDS transmission routes. There was generally a negative attitude towards HIV/AIDS infected people. This was shown in students' responses to some statements that AIDS was "a punishment for those infected for their immoral acts". Moreover, students expressed unwillingness to live with HIV/AIDS infected people. Students were positive in applying prevention, facilitating proper treatment for the diseased and believed that HIV/AIDS education in schools is a necessity. Their HIV/AIDS sources of information were mainly from written materials (journals, newspapers and books). It was concluded that, generally, students in this study had a good knowledge, and some positive attitudes about AIDS. However, the concerns they expressed in relation to their fears of sharing, or living with HIV/AIDS infected individuals, and some of their beliefs, need to be addressed more in the education prevention programs. Students need to be more knowledgeable about HIV/AIDS prevention. They indicated desires for more knowledge, especially as they become aware of the increasing risk of HIV/AIDS among adolescents in the Emirates. / Thesis (M.Cur.)-University of Natal, Durban, 2002

This paper presents the Social Phobia Psychotherapy Research Network. The research program encompasses a coordinated group of studies adopting a standard protocol and an agreed-on set of standardized measures for the assessment and treatment of social phobia (SP). In the central project (study A), a multicenter randomized controlled trial, refined models of manualized cognitive-behavioral therapy and manualized short-term psychodynamic psychotherapy are compared in the treatment of SP. A sample of 512 outpatients will be randomized to either cognitive-behavioral therapy, short-term psychodynamic psychotherapy or waiting list. Assessments will be made at baseline, at the end of treatment and 6 and 12 months after the end of treatment. For quality assurance and treatment integrity, a specific project using highly elaborated measures has been established (project Q). Study A is complemented by 4 interrelated add-on projects focusing on attachment style (study B1), on cost-effectiveness (study B2), on variation in the serotonin transporter gene in SP (study C1) and on structural and functional deviations of the hippocampus and amygdala (study C2). Thus, the Social Phobia Psychotherapy Research Network program enables a highly interdisciplinary research into SP. The unique sample size achieved by the multicenter approach allows for studies of subgroups (e.g. comorbid disorders, isolated vs. generalized SP), of responders and nonresponders of each treatment approach, for generalization of results and for a sufficient power to detect differences between treatments. Psychological and biological parameters will be related to treatment outcome, and variables for differential treatment indication will be gained. Thus, the results provided by the network may have an important impact on the treatment of SP and on the development of treatment guidelines for SP. / Dieser Beitrag ist mit Zustimmung des Rechteinhabers aufgrund einer (DFG-geförderten) Allianz- bzw.
