Effectiveness of cognitive behavioural group therapy for social phobia in a community clinic: a benchmarking study

This study used a benchmarking strategy to investigate the transportability of cognitive behavioural group therapy (CBGT) for social phobia to a community mental health clinic. The influence of common exclusion criteria on effect sizes was also examined. Patients (N=153) attended seven 4-h sessions of CBGT, which resulted in significant reductions in symptoms of social anxiety and depression. Effect sizes compared favourably to previous efficacy and effectiveness studies of both group and individual treatment. More than half of the treatment completers achieved reliable change. One-third achieved clinically significant change (CSC) on the Social Phobia Scale and the Beck Depression Inventory, but fewer achieved CSC on the Social Interaction and Anxiety Scale. Restricting the sample on the basis of depression symptoms, age above or below 50 years, comorbidity, alcohol problems, or student status did not significantly moderate effect sizes for social anxiety. It is concluded that CBGT is effective within community mental health clinics.     

Belief disconfirmation versus habituation approaches to situational exposure in panic disorder with agoraphobia: a pilot study

Exposure therapy and cognitive behaviour therapy (CBT) are both effective in the treatment of panic disorder with agoraphobia. Cognitive theories suggest that the way in which exposure to avoided situations is implemented in either treatment may be crucial. In particular, it is suggested that clinical improvement will be greatest if opportunities for disconfirmation of feared catastrophes are maximized. In a small pilot study, 16 patients with panic disorder and (moderate or severe) agoraphobia were randomly allocated to either habituation based exposure therapy (HBET) or exposure planned as a belief disconfirmation strategy and accompanied by dropping of safety-seeking behaviours. Both treatments were brief (total of 3.25 h of exposure) and were similar in terms of expectancy of change. Patients in the CBT condition showed significantly greater improvements in self-report measures of anxiety, panic and situational avoidance. They also completed significantly more steps in a standardized behavioural walk, during which they experienced significantly less anxiety. The controlled effect sizes for CBT were substantial (range 1.7-2.7), which suggests it may be a particularly efficient way of managing therapeutic exposure to feared situations in panic disorder with agoraphobia. Further research is needed to clarify the mechanism of change involved.     

Juvenile prostitution and community rehabilitation: an exploratory analysis of beliefs and values

A community, juvenile prostitution rehabilitation programme in Bogotá, Colombia, South America is described; and beliefs and values of the residents were explored. Multiple sorting procedures and multi‐dimensional scaling analysis elicited qualitative, structured, self‐report data, and investigated cognitive constructs. Participants discriminated between belief‐statements along two global dimensions: street‐life and prostitution; and rehabilitation. These were comprised of qualitatively different elements. Clinical implications for interventions with this group and the rehabilitation programme are discussed. Copyright © 2007 John Wiley & Sons, Ltd.     

A classmate in distress: schoolchildren as bystanders and their reasons for how they act

Research has shown that bystanders more often fail to or are slower to help a victim in emergency when there are other bystanders than when there are not. The study presented in this paper is a qualitative case study with a focus on students’ own reasons why they do not help a classmate in emergency when there are other children witnessing the emergency situation in the real-life classroom case studied. Grounded theory methods were used to analyse the data. The individual conversations with the students indicated a variety of definitions of the specific distress situation when they recalled and talked about the classroom incident. During the process of the analysis seven concepts of definitions associated with passive or non-intervention bystander behaviour were constructed and grounded in the empirical material: trivialisation, dissociation, embarrassment association, busy working priority, compliance with a competitive norm, audience modelling, and responsibility transfer. Relations between these concepts of definitions were also analysed. However, this study is a first step and a first report from an ongoing study about school children as helper and bystander.     

Weakly aggressive behaviour towards nymphs in the cockroach Schultesia nitor (Blattaria: Zetoborinae)

This paper describes aggressive behaviour in the cockroach Schultesia nitor, a tropical forest species living in bird nests. Young S. nitor nymphs are known to show active dispersal while old nymphs and adults are contrastingly strongly gregarious, a combination of features never observed in other cockroach species. Our laboratory experiments using video recording of confrontations between pairs show that aggressive behaviour towards conspecific nymphs is not exhibited towards nymphs of the species Phoetalia pallida, and thus can be considered species specific in S. nitor. But, it is not kin oriented: the mother and all adults of both sexes in different physiological states exhibit this behaviour as well. Six types of aggressive interactions were discriminated, occurring in age-symmetric pairs of nymphs and adults. Even more frequent aggression was exhibited by adults and last instar nymphs towards younger nymphs of all instars. The frequency of aggressive acts and types of aggressive interactions varied according to sex and size of the two interacting individuals. The possible function and evolution of this behaviour is discussed, with emphasis on the difficulty of interpreting obvious but weak and not kin-biased aggression.     

儿童孤独感与同伴关系、社会行为及社交自我知觉的研究

本研究采用同伴提名法和问卷调查法对3-6年级儿童共600名进行了研究,试图考察儿童孤独感与同伴关系、社会行为及社交自我知觉的关系。结果表明:(1)受欢迎组儿童的孤独感显著低于被拒绝组、被忽视组、有争议组和一般组;一般组儿童的孤独感显著低于被拒绝组和被忽视组。(2)社交自我知觉较高的儿童的孤独感显著低于社交自我知觉一般和较低的儿童,社交自我知觉一般的儿童的孤独感显著低于社交自我知觉较低的儿童。(3)高攻击型儿童的孤独感高于低攻击型儿童,但没有达到显著水平;高退缩型儿童的孤独感显著高于一般退缩型和低退缩型儿童,一般退缩型儿童的孤独感显著高于低退缩型的儿童。     

Regularity and/or consistency in the production of the past participle?

In the present study we have investigated the acquisition of the past participle of Italian verbs of the second (including mostly irregular verbs) and third (including mostly regular verbs) conjugations in school age children, and with simulations with an artificial neural network. We aimed to verify the extent to which children are sensitive to regularity, as opposed to the consistency in the mapping from the infinitive to the past participle. In particular, we predicted that children would learn at some point that verbs of the second conjugation tend to be irregular, and therefore they would be more likely to produce irregularizations for verbs of this class, compared to the verbs of the third conjugation. However, they should also show sensitivity to the phonological mapping consistency within each subclass, learning to produce correct forms on the basis of phonological similarity. In contrast, children should be more likely to produce regular forms for verbs of the third conjugation. Thus, a larger regularity effect would be expected for verbs of the third than of the second conjugation, leading to the prediction of a regularity by conjugation interaction.     

Gaze characteristics of elite and near-elite athletes in ice hockey defensive tactics

Traditional visual search experiments, where the researcher pre-selects video-based scenes for the participant to respond to, shows that elite players make more efficient decisions than non-elites, but disagree on how they temporally regulate their gaze. Using the vision-in-action [J.N. Vickers, J. Exp. Psychol.: Human Percept. Perform. 22 (1996) 342] approach, we tested whether the significant gaze that differentiates elite and non-elite athletes occurred either: early in the task and was of more rapid duration [A.M. Williams et al., Res. Quart. Exer. Sport 65 (1994) 127; A.M. Williams and K. Davids, Res. Quart. Exer. Sport 69 (1998) 111], or late in the task and was of longer duration [W. Helsen, J.M. Pauwels, A cognitive approach to visual search in sport, in: D. Brogan, K. Carr (Eds.), Visual Search, vol. II, Taylor and Francis, London, 1992], or whether a more complex gaze control strategy was used that consisted of both early and rapid fixations followed by a late fixation of long duration prior to the final execution. We tested this using a live defensive zone task in ice hockey. Results indicated that athletes temporally regulated their gaze using two different gaze control strategies. First, fixation/tracking (F/T) gaze early in the trial were significantly shorter than the final F/T and confirmed that the elite group fixated the tactical locations more rapidly than the non-elite on successful plays. And secondly, the final F/T prior to critical movement initiation (i.e. F/T-1) was significantly longer for both groups, averaging 30% of the final part of the phase and occurred as the athletes isolated a single object or location to end the play. The results imply that expertise in defensive tactics is defined by a cascade of F/T, which began with the athletes fixating or tracking specific locations for short durations at the beginning of the play, and concluded with a final gaze of long duration to a relatively stable target at the end. The results are discussed within the context of gaze research in open and closed skills, as well as theoretical models of long-term memory and decision making in sport.     

Advances in a cognitive behavioural model of body dysmorphic disorder

Body dysmorphic disorder (BDD) is the most distressing and handicapping of all the body image disorders. A cognitive behavioural model of BDD is discussed which incorporates evidence from recent studies and advances in the author’s 1996 conceptual model. The model aims to understand the maintenance of symptoms in BDD, to assist in the process of engagement of therapy and to guide the strategies to use. At the core of BDD is an excessive self-focussed attention on a distorted body image, the negative appraisal of such images leading to rumination, changes in mood and the use of safety behaviours. Evidence for possible risk factors in the development of BDD is also discussed.
