Clients in Simulated Teletherapy via Videoconference Compensate for Altered Eye Contact When Evaluating Therapist Empathy.

Eye contact is frequently associated with an increased perception of empathy and telepresence, but the currently used videoconferencing (VC) technologies diminish the possibility of naturally conveying eye contact. This study compared the empathy, telepresence, and eye gaze patterns of clients in simulated VC teletherapy sessions where eye contact was altered or facilitated. Forty-two would-be clients met with one of four therapists in training for one 20-min simulated teletherapy session taking place via VC. The session either altered or facilitated eye contact perception by manipulating the positioning of the webcams and of the clients in their chair. Eye-tracking data focusing on the eyes, face, and general body regions of interest were obtained for 25 clients. The results show that facilitating eye contact in VC did not increase the clients' perceptions of empathy or telepresence. However, empathy was associated with greater time spent looking at the eyes and faces of the therapists, but only in the sessions facilitating eye contact. We suggest that clients successfully rely on other verbal and nonverbal cues to detect therapist empathy when eye contact is altered in teletherapy sessions.

[Basic, Clinical and Social Perspectives on the Use of Virtual Characters in Mental Health]. / Perspectives fondamentale, clinique et sociétale de l'utilisation des personnages virtuels en santé mentale.

Along other breakthroughs in computer sciences, such as artificial intelligence, virtual characters (i.e. digitally represented characters featuring a human appearance or not) are foreseen as potential providers of mental healthcare services. However, their current use in clinical practice is marginal and limited to an assistive role to help clinicians in their practices. Safety and efficiency concerns, as well as a general lack of knowledge and experience, may explain this discrepancy between the expected (sometimes futuristic) and current use of virtual characters. An overview of recent evidence would help pinpoint the main concerns and challenges pertaining to their use in mental healthcare. Objective This paper aims to inform relevant actors, including clinicians, on the potential of virtual characters in mental healthcare practices and to raise awareness on societal challenges regarding their use. Method A narrative literature review was conducted to summarize basic and clinical research findings, and to outline an in-depth discussion on various societal caveats related to the inclusion of virtual characters. Results Basic studies highlight several characteristics of the virtual characters that seem to influence patient-clinician interactions. These characteristics can be classified into two categories: perceptual (e.g. realism) and social features (i.e. attribution of social categories such as gender). To this day, many interventions and/or assessments using virtual characters have shown various levels of efficiency in mental health, and certain elements of a therapeutic relationship (e.g. alliance and empathy) may even be triggered during an interaction with a virtual character. To develop and increase the use of virtual characters, numerous socioeconomic and ethical issues must be examined. Although the accessibility and the availability of virtual characters are an undeniable advantage for their use in mental healthcare, some inequities about their application remain. In addition, the accumulation of biometric data (e.g. heart rate) could provide valuable information to clinicians and could help develop autonomous virtual characters, which raises concerns over issues of security and privacy. This paper proposes some recommendations to avoid such undesirable outcomes. Conclusion Due to their promising features, the inclusion of virtual characters will no doubt be increasingly prevalent in mental healthcare services. All involved actors should thus be informed about specific challenges raised by such breakthroughs. They should also actively participate in discussions regarding the development of virtual characters in order to adopt unified recommendations for their safe and ethical use in mental healthcare.

I Can But I Shall Not Always Be Empathic.

Empathy, a core process for social interactions, is the capacity to understand and share others' mental states and emotions. Each individual is thought to have a maximum level of empathy (empathic ability) and a spontaneous tendency to express it (empathic propensity), which can be affected by multiple factors. Two within-subject studies were conducted to assess the malleability of empathy by modulating contextual factors and measuring their interaction with psychological characteristics. In Study 1, 59 healthy adults evaluated their empathy for people showing facial expressions of pain following different instructions: Passive Observation and Instruction to Actively Empathize. In Study 2, 56 healthy adults performed a similar task under two conditions: Passive Observation and Observation under a Cognitive Load. The results revealed that empathy was significantly increased in the actively empathizing condition (Study 1) and under a cognitive load, but more importantly for men (Study 2). The level of change between the two conditions was associated with self-reported empathy, autistic, alexithymia and psychopathic traits (Study 1), as well as with working memory capacities and the level of empathy reported in the passive observation condition (Study 2). These findings suggest that an instruction to actively empathize and, surprisingly, a cognitive load can both increase empathy, but not for the same individuals. An instruction to actively empathize seems to increase empathy for individuals with good empathic dispositions, while a cognitive load enhances empathy in people for which empathic propensity is sub-optimal.

An interprofessional qualitative study of barriers and potential solutions for the safe use of insulin in the hospital setting.

OBJECTIVE: Insulin is regularly used in hospitalized patients for glycemic control but is associated with significant risks. The goals of this study were to describe the strengths and weaknesses of a university health centre in the safe use of insulin, to collect improvement proposals from health professionals involved in the management of insulin therapy and to assess inpatient glycemic control. METHODS: This is a qualitative study. Physicians, nurses and pharmacists practising at the Centre Hospitalier Universitaire de Sherbrooke (CHUS) for at least 2 years were invited to join focus groups on safe insulin treatment. Themes up for discussion were roles of professionals in insulin therapy, problems encountered, solutions put forward and strengths of the hospital. The Quality Hyperglycemia Score (QHS) was assessed using an existing cohort of inpatients who were prescribed insulin. RESULTS: A total of 5 focus groups were held in February and March of 2012, involving 31 healthcare professional participants. Several groups pointed out the same problems, namely, lack of access to useful information for optimal management of insulin therapy and lack of communication among personnel on different work shifts. Results of the QHS suggest room for improvement in blood glucose control at our institution. CONCLUSION: These focus groups allowed better identification of the management problems related to the use of insulin in our health institution and possible interventions to solve them. The QHS will be reassessed to measure quality of inpatient glycemic control over time.

Intervention focused on the patient and family for better postoperative pain relief.

Hip arthroplasty results in high-intensity postoperative pain. To counter this, a multimodal approach (combining pharmacologic and nonpharmacologic strategies) is recommended. The involvement of the patient and family is also suggested, but there are few examples. The purpose of this study was to measure the effects of a patient and family-centered educational intervention (accompanying family member), promoting nonpharmacologic strategies, about pain relief, anxiety, and the pain-coping strategies used. The intervention took the family into consideration by recognizing its expertise, existence, experience, and need for hope. Thirty-three patients took part in this quasiexperimental study, all being accompanied by a significant other (control group [CG]: n = 17; experimental group [EG]: n = 16). The control group received conventional treatment and the experimental group received the intervention. The results show that EG members experienced less intense pain on postoperative days 2 (2.75 vs. 5.14; p = .001) and 4 (2.17 vs. 4.00; p = .01). EG members reported less anxiety (29.50 vs. 37.00; p = .041). EG members used significantly fewer negative pain-coping strategies, such as ignorance and dramatization. The results suggest that a patient and family-centered educational intervention (accompanying family member), promoting nonpharmacologic strategies, should be routinely used in combination with the multimodal approach. This combination improves pain management, lowers anxiety, and facilitates the use of positive postoperative coping strategies.

Validation of a thermal bias control technique for Coda Wave Interferometry (CWI).

The Coda Wave Interferometry (CWI) analysis serves to monitor the variation of propagation velocity in a heterogeneous medium with high precision (10(-3)% in relative terms). In combination with acoustoelastic theory, this type of analysis offers an NDT method for stress evaluation and/or damage detection. Since the CWI method is intended to evaluate extreme levels of accuracy, the presence of bias under certain circumstances can undermine evaluation results and/or test repeatability. In this paper, we offer a bias control technique involving the use of a second (reference) specimen for CWI analysis that is designed to compensate: (1) the thermally-induced velocity variation due to environmental temperature fluctuations; and (2) bias originating from experimental procedures. The presentation of this technique contains both a theoretical analysis and experimental protocol for the purpose of implementation. Furthermore, comparisons of experimental results have been included in order to demonstrate the utility of this bias control technique under laboratory conditions.

Study of stress-induced velocity variation in concrete under direct tensile force and monitoring of the damage level by using thermally-compensated Coda Wave Interferometry.

In this paper, we describe an experimental study of concrete behavior under a uniaxial tensile load by use of the thermally-compensated Coda Wave Interferometry (CWI) analysis. Under laboratory conditions, uniaxial tensile load cycles are imposed on a cylindrical concrete specimen, with continuous ultrasonic measurements being recorded within the scope of bias control protocols. A thermally-compensated CWI analysis of multiple scattering waves is performed in order to evaluate the stress-induced velocity variation. Concrete behavior under a tensile load can then be studied, along with CWI results from both its elastic performance (acoustoelasticity) and plastic performance (microcracking corresponding to the Kaiser effect). This work program includes a creep test with a sustained, high tensile load; the acoustoelastic coefficients are estimated before and after conducting the creep test and then used to demonstrate the effect of creep load.
