Single prolonged stress disrupts retention of extinguished fear in rats

Clinical research has linked post-traumatic stress disorder (PTSD) with deficits in fear extinction. However, it is not clear whether these deficits result from stress-related changes in the acquisition or retention of extinction or in the regulation of extinction memories by context, for example. In this study, we used the single prolonged stress (SPS) animal model of PTSD and fear conditioning procedures to examine the effects of prior traumatic stress on the acquisition, retention, and context-specificity of extinction. SPS administered one week prior to fear conditioning had no effect on the acquisition of fear conditioning or extinction but disrupted the retention of extinction memories for both contextual and cued fear. This SPS effect required a post-stress incubation period to manifest. The results demonstrate that SPS disrupts extinction retention, leading to enhanced fear renewal; further research is needed to identify the neurobiological processes through which SPS induces these effects.     

Unconditioned freezing is enhanced in an appetitive context: implications for the contextual dependency of unconditioned fear

It has been well established that expression of conditioned fear is context independent, but the context dependency of unconditioned fear expression has rarely been explored. A recent study reported that unconditioned freezing in rats is enhanced in a familiar context, which suggests that unconditioned fear expression can be modulated by contextual processing. In order to further explore this possibility we examined unconditioned freezing in novel, familiar, and appetitive contexts; and attempted to identify brain regions critical for context-related changes in unconditioned freezing by measuring c-Fos mRNA levels in emotional circuits. Unconditioned freezing was enhanced in the appetitive context, and this enhancement was accompanied by increased c-Fos mRNA expression in the medial amygdala and hippocampus, but attenuated expression in the medial prefrontal cortex. In the appetitive context, expectation of a reward coupled with detection of threat may have enhanced unconditioned fear expression, which suggests that unconditioned fear expression can be modulated by contextual factors. Context-related expectancy mismatch may explain the enhancement of unconditioned fear expression seen in this study and warrants further examination.     

Emotional support and counselling for people with visual impairment: Quantitative findings from a mixed methods pilot study

Aims: This paper reports on mainly quantitative findings from a mixed methods evaluation of a new model of emotional support and counselling for people with moderate visual impairment. Method: The CORE Outcome Measure was completed with service users at baseline and post‐intervention to assess the impact of the new service on psychological wellbeing and social functioning. Their perceived needs and expectations of the service were also explored. Results: Of the 35 individuals providing data at each assessment time, mean item scores on the CORE fell significantly (p<.001), taking the sample from within a clinical population before therapy, to a mean score below this following therapy. A more positive outlook accompanied this improvement in functioning. Discussion: Findings from the study augment the growing evidence that emotional support and counselling services can play an important role alongside and within related vision services. Implications for practice: The study indicates that therapeutic input for the visually impaired client group may need to target both wellbeing (feelings about oneself and the future) and problems (depression, anxiety, physical health, and trauma). Conclusions: Our findings suggest that a dual model of emotional support and counselling offers considerable benefit for people with visual impairment.

Can boundary crossings in clinical supervision be beneficial?

Published studies have addressed boundary violations by clinical supervisors, but boundary crossings, particularly those deemed positive by supervisees, have not received much attention. Eleven trainees in APA-accredited doctoral programs in clinical and counseling psychology were interviewed regarding positive boundary crossings (PBCs) they experienced with clinical supervisors. Interview data were analyzed using Consensual Qualitative Research. Examples of PBCs included socializing with supervisors outside the office, sharing car rides, and supervisor self-disclosure. Typically, supervisees did not discuss the PBC with their supervisors because they were uncomfortable doing so, felt that the PBC was normal, or felt that processing such issues was not part of the supervisor’s style. Most supervisees viewed the PBCs as enhancing the supervisory relationship and their clinical training; however, some participants reported that the PBCs created role confusion. The results suggest that there are legitimate reasons for supervisors to be scrupulous about their boundaries with supervisees; however, supervisors who hold rigid boundaries can deprive supervisees of deeper mentoring relationships or a more authentic emotional relationship that can be valuable to supervisees learning how to provide psychotherapy.     

Improving Treatment Plan Implementation in Schools: A Meta-analysis of Single Subject Design Studies

Twenty-nine peer-reviewed journal articles that analyzed intervention implementation in schools using single-case experimental designs were meta-analyzed. These studies reported 171 separate data paths and provided 3,991 data points. The meta-analysis was accomplished by fitting data extracted from graphs in mixed linear growth models. This analytic approach was adopted to provide a model whose assumptions were met and could model both level and trend. The extent to which interventions were implemented as planned in baseline was low with a downward trend. Performance feedback, performance feedback augmented with additional procedures, and self-monitoring with environmental supports were found to be highly effective for improving intervention implementation. Follow-up meetings without review of implementation data were ineffective. Maintenance data were positive across studies. Implications of the results for future research and practice are discussed.     

Trust and Goodwill as Attractors: Reflecting on a Complexity-Informed Inquiry

This article discusses a complexity-informed review and evaluation project. Complexity-informed methods and techniques are used to fashion understanding of the relationships and processes implicated between the service agencies constituting the Youth Accommodation Interagency—Nepean (YAIN) and their Resource Worker, the influence of these relationships and processes on the achievement of desired and required goals, and the potential for replication of these relationships and processes elsewhere. The article concludes with critical reflection regarding what was learnt from utilizing complexity in this qualitative inquiry.
