abstract = {Background: Body image disturbance has been associated with various health conditions and has the potential to trigger the development of unhealthy behaviors, including dysfunctional attitudes and eating behaviors, which may evolve into eating disorders. This study explores the relationship between body image variables—such as global self-worth, physical self-worth, and physical attractiveness—and the continuum of eating attitudes and behaviors. Methods: A canonical correlation analysis was performed to assess the multivariate relationship between attitudinal and perceptual variables and the continuum of eating behaviors, with a total of 113 cases analyzed. Results: The findings indicate that intuitive eating and a positive body image (including global self-worth and physical attractiveness) are most strongly associated with the functional end of the continuum, while disordered eating behaviors and body dissatisfaction are linked to the dysfunctional end. Conclusions: These results suggest that interventions targeting the emotional and attitudinal dimensions of body dissatisfaction, whether delivered in vivo or via virtual reality (e.g., weight exposure), may facilitate a shift toward healthier, more functional eating behaviors along the continuum. © 2025 by the authors.},

A focus group design was used to collect data from the therapists, and emerging common themes were identified by thematic analysis. Results: Therapists felt they could build strong alliances and communicate emotions and empathy effectively, although the lack of nonverbal cues posed some challenges. The intervention, according to participating therapists, was less suitable for participants in high-stress situations and in case of discrepancy between client expectations and the intervention content. Moreover, the therapists perceived specific interventions as easy-to-use or as more challenging based on their complexity and on the therapist support needed for executing them. Client engagement in the program emerged as an underlying theme that had fundamental impact on alliance, communication, and ultimately, treatment efficiency.

abstract = {Many studies have revealed cultural differences in the way Easterners and Westerners attend to their visual world. It has been proposed that these cultural differences reflect the utilization of different processes, namely holistic processes by Easterners and analytical processes by Westerners. In the face processing literature, eye movement studies have revealed different fixation patterns for Easterners and Westerners that are congruent with a broader spread of attention by Easterners: compared with Westerners, Easterners tend to fixate more toward the center of the face even if they need the information provided by the eyes and mouth. Although this cultural difference could reflect an impact of culture on the visual mechanisms underlying face processing, this interpretation has been questioned by the finding that Easterners and Westerners do not differ on the location of their initial fixations, that is, those that have been shown as being sufficient for face recognition. Because a broader spread of attention is typically linked with the reduced sensitivity to higher spatial frequency, the present study directly compared the spatial frequency tuning of Easterners (Chinese) and Westerners (Canadians) in 2 face recognition tasks (Experiment 1 and 2), along with their general low-level sensitivity to spatial frequencies (Experiment 3). Consistent with our hypothesis, Chinese participants were tuned toward lower spatial frequencies than Canadians participants during the face recognition tasks, despite comparable low-level contrast sensitivity functions.

abstract = {It is generally thought that faces are perceived as indissociable wholes. As a result, many assume that hiding large portions of the face by the addition of noise or by masking limits or qualitatively alters natural "expert" face processing by forcing observers to use atypical processing mechanisms. We addressed this question by measuring face processing abilities with whole faces and with Bubbles (Gosselin & Schyns, 2001), an extreme masking method thought by some to bias the observers toward the use of atypical processing mechanisms by limiting the use of whole-face strategies. We obtained a strong and negative correlation between individual face processing ability and the number of bubbles (r = -.79), and this correlation remained strong even after controlling for general visual/cognitive processing ability (rpartial = -.72). In other words, the better someone is at processing faces, the fewer facial parts they need to accurately carry out this task.

abstract = {Telemental health is the use of information and communications technologies and broadband networks to deliver mental health services and support wellness. Although numerous studies have demonstrated the efficiency and utility of telemental health, certain barriers may impede its implementation, including the attitudes of mental health service providers. The current study draws on the technology acceptance model (TAM) to understand the role of mental health service providers’ attitudes and perceptions of telemental health (psychotherapy delivered via videoconferencing) on their intention to use this technology with their patients. A sample of 205 broadly defined mental health service providers working on 32 First Nations reserves in the province of Quebec completed the questionnaire adapted to assess TAM for telepsychotherapy. Confirmatory factor analysis and structural equation modeling provided evidence for the factor validity and reliability of the TAM in this sample. The key predictor of the intention to use telepsychotherapy was not mental health providers’ attitude toward telepsychotherapy, nor how much they expected this service to be complicated to use, but essentially how useful they expect it to be for their First Nations patients. If telemental health via videoconferencing is to be implemented in First Nations communities, it is essential to thoroughly demonstrate its utility to mental health providers. Perceived usefulness will have a positive impact on attitudes toward this technology, and perceived ease of use will positively influence perceived usefulness. Cultural issues specific to the populations receiving telemental health services may be more efficiently addressed from the angle of perceived usefulness. © 2013, SAGE Publications.
