Objective: The aim of this study is to improve the understanding of self-changes after an intervention for depression focused on implicative dilemmas, a type of cognitive conflict related to identity. As recent research has highlighted the relevance of identity-related dilemmas in clients with depression, we sought to assess the way in which clients resolve such inner conflicts after a tailored dilemma-focused intervention and how this is reflected in the clients’ self-narratives. Method: We used three instruments to observe differences between good (n?=?5) and poor (n?=?5) outcome cases: (i) the Repertory Grid Technique to track the resolution of dilemmas, (ii) the Change Interview to compile clients’ accounts of changes at posttreatment, and (iii) the Innovative Moments Coding System to examine the emergence of clients’ novelties at the Change Interview. Results: Groups did not differ in terms of the number and relevance of client-identified significantly helpful events. However, between-group differences were found for the resolution of dilemmas and for the proportion of high-level innovative moment (IM) types. Furthermore, a greater self-narrative reconstruction was associated with higher levels of symptom improvement. Conclusions: Good outcome cases seem to be associated with the resolution of conflicts and high-level IMs. 相似文献

Objective: We investigated the application of 51 autosomal short tandem repeat (STR) loci with the identity by state (IBS) method and a discriminant function algorithm in full-sib identification. Methods: A total of 342 pairs of full sibs (FSs) and 3900 pairs of unrelated individuals (UIs) were genotyped for 51 STR loci. Groups were formed in accordance with discrimination power (DP) values and the number of loci, and IBS scores of FSs and UIs were analyzed and compared. The discriminant functions of FS-UI were determined by using the Fisher discriminant with SPSS software. Results: All IBS in FSs and UIs groups showed normal distributions and there were significant differences between FS-UI. Receiver operating characteristic curves revealed that the detection efficiency of full-sib identification was affected by both the locus polymorphism and the number of loci detected. Comparing the rate of false positive and false negative of discriminant function between groups, a higher average DP value and larger number of loci detected were associated with a lower rate of miscarriage of justice and were more helpful for full-sib identification. Conclusion: STRs with higher DP values should be selected when additional autosomal markers are required for FS identification. Discriminant analysis with the IBS method is highly applicable for the FS-UI test. 相似文献

Yerxa’s [1] model of an integrated profession depicts a circular scholarly process whereby ideas formed in practice are subjected to research and then returned to practice through education. This knowledge-generating cycle supports occupational science and the development of our professional identity. The aim of this article is to demonstrate how Yerxa’s model was used to evaluate if three developmental cycles of the ADL-Focused Occupation-Based Neurobehavioral Evaluation (A-ONE) sufficiently represented all necessary model components required for implementation into practice. The three cycles were historical, educational and measurement. The necessary components included: (a) dilemmas in practice, (b) new ideas that emerged from those practice issues, (c) research to test those ideas and (d) education designed to integrate new knowledge into practice. The results of this analysis of the A-ONE supported adequate research related to ideas from practice being implemented back into practice. Through using the model of an integrated profession to reflect on ideas ignited within practice, and then implementing research to explore the potential contribution of those ideas to knowledge generation, we gain the power to influence the future development of occupational science and the profession. 相似文献

ABSTRACT For a nationwide Geriatric Interdisciplinary Team Training (GITT) program evaluation of 8 sites and 26 teams, team evaluators developed a quantitative and qualitative team observation scale (TOS), examining structure, process, and outcome, with specific focus on the training function. Qualitative data provided an important expansion of quantitative data, highlighting positive effects that were not statistically significant, such as role modeling and training occurring within the clinical team. Qualitative data could also identify “too much” of a coded variable, such as time spent in individual team members' assessments and treatment plans. As healthcare organizations have increasing demands for productivity and changing reimbursement, traditional models of teamwork, with large teams and structured meetings, may no longer be as functional as they once were. To meet these constraints and to train students in teamwork, teams of the future will have to make choices, from developing and setting specific models to increasing the use of information technology to create virtual teams. Both quantitative and qualitative data will be needed to evaluate these new types of teams and the important outcomes they produce. 相似文献

ABSTRACT Most clinicians working with dissociative identity disorder (D.I.D.) recognize the importance of working towards a cooperative system especially during the initial stages of treatment. However, achieving this can be a monumental task given the inner war that goes on inside the mind of an individual diagnosed with D.I.D. From an ego-state theoretical framework, this article will demonstrate through clinical cases and artwork, the value of imagery techniques in changing internal perceptions, especially with regards to introject ego states. These changes can assist in eliciting more internal cooperation, a necessary task prior to working towards a collaborative, co-conscious system or what some theorists would call integration. 相似文献

Cystic fibrosis (CF) results in increased energy requirements at rest. However, the energy expended during physiotherapy management is unknown. The aim of this study, therefore, is to examine the energy expended during two commonly used forms of chest physiotherapy in CF subjects. Twenty-six CF subjects completed a randomised crossover trial with 48 hours between treatments. Two regimens of treatment were conducted: therapist-assisted treatment (active cycle of breathing, ACBT, with percussion, vibration), and independent treatment (ACBT alone, under the supervision of a physiotherapist). Subjects completed pulmonary function tests before and after either treatment. Indirect calorimetry and oximetry parameters were recorded at rest, during, and following treatment. Treatment groups were compared using ANOVA and two-sample crossover t-tests. When compared to resting values, physiotherapy treatment resulted in significant increases in VO2, VCO2 and respiratory exchange ratio. No difference was evident between treatment regimens for the change in VO2 between baseline and treatment. The increase in ventilation (baseline to treatment) was significantly greater for the therapist-assisted treatment. The therapist-assisted ACBT was associated with a significant carryover effect for forced expiratory flow at 50% of vital capacity (FEF50). Oxygen requirements for the two treatments were similar. However, the assisted regimen resulted in greater changes in minute ventilation during treatment and improved 48-hour post-treatment pulmonary function after only one treatment session. These findings suggest that the inclusion of percussion and vibration within the ACBT may influence respiratory muscle activity during treatment and result in improved pulmonary function. 相似文献

ABSTRACT The Waves, written in 1931 by Virginia Woolf, is an astounding depiction of an internal landscape richly full of dissociative phenomena. Although applauded for its genius and considered by many to be her highest literary achievement, critics complained that the language of the characters seemed artificial and a departure from the usual interior monologue appearing in other works that utilized stream of consciousness writing at the time. Woolf believed this work to be misunderstood as she often felt herself. This paper illustrates how The Waves might metaphorically connote the internal experiences of dissociating. The narrative of the novel illuminates the mapping of Woolf's internal system as it changes across a life span. Woolf deftly submerged not only the facts of her personal life in The Waves but, more important, revealed through both her literary method and language the dissociative nature of her own mind. By extrapolating from Woolf's autobiographies, journals, and letters, the parallels between fact and fiction become apparent. 相似文献

ABSTRACT This paper describes and illustrates the two-part film (TPF) technique, an intervention characteristic of the Collective Heart model (Krakauer, 2001), a phase-oriented approach to treating dissociative disorders. Emphasis is on the technique's value in interdicting maladaptive interpersonal and intrapersonal patterns which perpetuate depression, anxiety, dissociation, and self-defeating behaviors. The approach is compared with similar internal screen techniques appearing in the hypnotic literature, and distinctive features of the TPF are noted. These include the minimally directive role of the therapist, reliance on the inner wisdom of the client, present and future orientation, and amplification of desired affective and somatic experiences. A verbatim clinical illustration is presented and discussed, with emphasis on the empowering impact of the TPF. 相似文献
