The impact of dialectical behaviour therapy training on therapists in Singapore: A mixed-methods study

Background

While dialectical behaviour therapy (DBT) has much empirical support for treating borderline personality disorder (BPD) and other conditions, little research has examined the dissemination of DBT in Southeast Asia.

Aims

This study evaluated training outcomes following a 5-day intensive DBT training programme in a group of psychologists in Singapore, who were in the process of implementing DBT as part of the training's objectives.

Methodology

A mixed-methods design was employed. Fourteen psychologists from a public psychiatric hospital in Singapore were recruited. Seven self-selected into DBT training, and the remaining were matched controls who were not attending the training programme. The latter served as a nonrandomised control group. Prior to and 3 months after training, all participants completed measures of stigma towards BPD patients, burnout and therapeutic alliance. DBT training participants additionally attended a focus group discussion assessing their experiences and challenges implementing DBT in Singapore's context.

Findings

Quantitative analyses using mixed ANOVA showed that, compared with controls, DBT-trained participants demonstrated significantly greater increases in acceptance towards BPD patients. No between-group differences were found on changes in burnout or therapy alliance with patients. Analyses of qualitative data using thematic analysis revealed that DBT training impacted the way participants conceptualised and delivered therapy for BPD patients, and highlighted several challenges in implementing DBT in the local hospital context.

Conclusion

The findings demonstrate the potential of DBT training in improving clinicians' attitudes towards BPD patients and support a need for policymakers to prepare organisations for DBT implementation to ensure programme sustainability.     

Velocities of motor and sensory nerve conduction are the same for right and left arms in right- and left-handed normal subjects

The velocities of motor and sensory conduction of median and ulnar nerves were measured on the left and right arms of 33 right-handed and 12 left-handed normal subjects. Contrary to current knowledge there was no statistically significant difference in the velocities of nerve conduction on the left and right sides of these subjects. It was suggested that the differences in the velocities of nerve conduction cannot contribute to the mechanisms of handedness.     

Information transmission with a multifinger tactual display

In this work, the tactual information transmission capabilities of a tactual display designed to provide stimulation along a continuum from kinesthetic movements to cutaneous vibrations are assessed. The display is capable of delivering arbitrary waveforms to three digits (thumb, index, and middle finger) within an amplitude range from absolute detection threshold to about 50 dB sensation level and a frequency range from dc to above 300 Hz. Stimulus sets were designed at each of three signal durations (125, 250, and 500 msec) by combining salient attributes, such as frequency (further divided into low, middle, and high regions), amplitude, direction of motion, and finger location. Estimated static information transfer (IT) was 6.5 bits at 500 mseC., 6.4 bits at 250 mseC., and 5.6 bits at 125 msec. Estimates of IT rate were derived from identification experiments in which the subject’s task was to identify the middle stimulus in a sequence of three stimuli randomly selected from a given stimulus set. On the basis of the extrapolations from these IT measurements to continuous streams, the IT rate was estimated to be about 12 bits/seC., which is roughly the same as that achieved by Tadoma users in tactual speech communication.     

Experience as art

Chinese philosophy views experience as intrinsically aesthetic. This world view could be elucidated through a consideration of John Dewey's aesthetics and features of Chinese art. Dewey's philosophy of art starts with an understanding of experience as ‘live processes’ of living creatures interacting with their environment. Such processes are autopoietic in being self‐sustaining, ever‐changing, capable of increasing complexity, capable of generating novelty, direction and progress on its own. Its autopoietic character is a precondition of the aesthetic in the process of experience. An aesthetic experience is rhythmic, focused, consummatory, and reaches beyond the transitory boundaries of concrete existence. The aesthetic is not confined to what is conventionally identified as art. Most important, the ethical‐political, the natural and the cosmic all have an aesthetic aspect, as the paper attempts to show by examining classical Confucianism.     

汉字的视觉识别过程:对形码和音码作用的考察

本实验应用启动条件下的词汇判断法,探讨了字形和语音在汉字视觉识别过程中的作用。实验发现,当启动词中的某个成分字和目标字形状相似时,被试对目标字的反应速度显著加快,表明特征分析是汉字识别的必经阶段;启动词中的多音字不但会促进被试对和其适当读音相近的目标字的反应,而且会促进被试对和其不适当读音相近的目标字的反应。这就明,在到达心理词典之前,熟悉的中文字词的语音特征已经得到了自动的激活。     

胼胝体分步全切病人左右侧命名的不对称

以一位第一次进行胼胝体前部切开,第二次作后部切开的胼胝体全切断患者为被试,在第二次手术前后进行了Ⅰ。左右单侧操作检查,和Ⅱ。两半球之间感觉信息传递两类神经心理学实验。结果提示:后部切断前,左右侧操作没有明显的差异。同时,视觉和触觉的感觉信息的传递基本正常。在后部切断后,命名作业呈右视野和右手优势,图形临摹左手似乎较好,这时视觉和触党的感觉信息的传递发生了障碍。左视野和左手命名高于随机水平,讨论了这一结果与右脑语言的关系。方位比较等多个实验提供了支持两半球协同活动理论的证据。     

Harmonic structure as a determinant of melodic organization

Musicians and nonmusicians indicated whether a two-note probe following a tonally structured melody occurred in the melody. The critical probes were taken from one of three locations in the melody: the two notes (1) ending the first phrase, (2) straddling the phrase boundary, and (3) beginning the second phrase. As predicted, the probe that straddled the phrase boundary was more difficult to recognize than either of the within-phrase probes. These findings suggest that knowledge of harmonic structure influences perceptual organization of melodies in ways analogous to the influence of clause relations on the perceptual organization of sentences. They also provide evidence that training plays an important role in refining listeners’ sensitivity to harmonic variables.     

Toward the differentiation of trust in supervisor and trust in organization

Trust in supervisor and trust in organization are argued to be distinct but related constructs, each with its own set of antecedents and outcomes. Empirical field results supported the proposition. Although trust in supervisor and trust in organization were positively and significantly correlated, trust in supervisor was more strongly associated with proximal variables (ability, benevolence, and integrity of supervisor), whereas trust in organization was more strongly correlated with global variables (perceived organizational support and justice). This conclusion held despite the inclusion of proximal variables in the regression on trust in organization and the inclusion of global variables in the regression on trust in supervisor. In addition to the differential antecedents of trust in supervisor and trust in organization, the outcomes for both variables were different. Trust in supervisor was related to increased innovative behavior and satisfaction with supervisor, and trust in organization was related to higher organizational commitment and lower intention to leave. Therefore, the authors provide clear preliminary data on the distinctiveness of trust in supervisor and trust in organization. One implication of this set of results is that organizations should adopt a more holistic approach in building trust, which can be achieved by focusing on the various constituents of the organization and the various levels (e.g., the supervisor level and the organizational level).     

冲突视阈下类别信息与个体信息知觉负载的认知控制效应

个体根据知觉选择、反应偏向以及实时更新的情境信息调节自身状态,以适应性地促进对当前知觉信息的灵活编码,这一过程即为印象形成的认知控制。采用词语判断任务与侧抑制任务的变式将他人信息(类别信息vs.个体信息)分成高、低知觉负载两种水平,考察了冲突视阈下认知控制策略对他人印象形成的调控作用及知觉负载的效应。结果发现:(1)知觉负载影响他人印象形成的认知控制策略。(2)当类别信息与个体信息存在知觉冲突且个体的知觉负载较高时,受到反应性控制的作用,他人印象形成易出现冲突适应偏向; 当个体的知觉负载较低时,他人印象形成易受主动性控制的作用,从而产生冲突抑制偏向。这些结果表明,当个体形成他人印象时,其认知控制策略因受知觉负载影响而呈现分阶段加工特征。     

Medical Students’ Creation of Original Poetry,Comics, and Masks to Explore Professional Identity Formation

Introduction. This study examines differences in students’ perceived value of three artmaking modalities (poetry, comics, masks) and whether the resulting creative projects offer similar or different insights into medical students’ professional identity formation. Methods. Mixed-methods design using a student survey, student narrative comments and qualitative analysis of students’ original work. Results. Poetry and comics stimulated insight, but masks were more enjoyable and stress-reducing. All three art modalities expressed tension between personal and professional identities. Discussion. Regardless of type of artmaking, students express concern about encroachments of training on personal identity but hoped that personal and professional selves could be integrated.
