Data set and methodology involving pedagogical approaches to teach mental health and substance use in dental education.

OBJECTIVE: In this Data note, we provide a raw data set in the form of brief self-guided reflections. We also present the methodological approach to generate these reflections including an educational vignette so that other dental schools can plan for their teaching activities involving mental health and substance use topics. DATA DESCRIPTION: Between 2015/16 and 2018/19, the University of British Columbia's (UBC) undergraduate dental and dental hygiene students submitted optional written guided reflections to address 'how can an educational vignette, depicting a patient with a history of substance use and mental health disorders accessing dental care, promote an open dialogue about stigma?' From a total of 323 undergraduate students, 148 anonymous reflections between 200 and 400 characters each were received. The main ideas that may emerge from the reflections include 'exploring power relations' and 'patient-centered care approach to counteract stigma'.

The role of an educational vignette to teach dental students on issues of substance use and mental health disorders in patients at the University of British Columbia: an exploratory qualitative study.

BACKGROUND: Inverted classroom approaches and the use of vignettes have been suggested in health care education. The objective of this study was to use an educational vignette to discuss issues of stigma around substance use and mental disorders within undergraduate Doctor of Medicine in Dentistry (DMD) and Bachelor of Dental Science in Dental Hygiene (BDSc-DH) students at the University of British Columbia, Canada. Our research question was "how can an educational vignette, depicting a fictitious patient with a history of substance use and mental health disorders accessing dental care, promote an open dialogue about stigma?" METHODS: An educational vignette was developed based on individuals' lived-experiences with a variety of substance use and/or mental health disorders. This vignette was used to generate in-class discussion involving all the DMD and BDSc-DH undergraduate students enrolled between 2015/16 and 2018/19 who attended a mandatory 2.5 h didactic session using an inverted classroom approach. Students were also encouraged to provide a post-class voluntary written reflection, between 200 and 300 words, around stigma. The authors took written field notes on students' response to the vignette and used excerpts from students' de-identified reflections to illustrate the impact of such an educational tool. RESULTS: A total of 323 DMD and BDSc-DH students attended the didactic sessions between 2015/16 and 2018/19, and 148 reflections were submitted over the same time period. The inverted classroom approached showed to be engaging and collaborative. The vignette promoted open dialogue and was determined to be a conducive tool to generate in-class discussion and reflection. Major themes from the textual data included 'exploring power relations' and 'patient-centered care approach to counteract stigma'. The vignette also enabled the discussion of positive experiences characterized by empathy, reassurance and communication, although it might not have prompted all students to participate in class or in writing the reflections. CONCLUSION: The inverted classroom approach and the vignette seemed to be an effective way to facilitate dialogue and reflection for most students. This study highlighted the need to explore innovative ways in which to continuously prepare current and future oral health care providers to professionally address the needs of patients with a history of substance use and/or mental health disorders.

Stigma of addiction and mental illness in healthcare: The case of patients' experiences in dental settings.

OBJECTIVE: To explore the ways in which stigma is experienced in healthcare and dental settings by patients with a history of addiction and mental illness. METHODS: Audio-recorded, semi-structured interviews with a purposefully selected convenience sample of residents from two community treatment centres in Vancouver, Canada were conducted. The interview guide contained questions about experiences while seeking health and dental care and was based on an existing framework of labeling, stereotyping, exclusion, discrimination, and power imbalance. Interviews were transcribed verbatim for coding and thematic analysis. RESULTS: Twenty-five participants between 23 and 67 years of age were interviewed; 17 were males. Most had a self-reported history of depression combined with use of alcohol and crack-cocaine; most of them only sought dental care for emergency purposes. Textual analysis of more than 300 pages of transcribed interviews revealed that participants perceived stigma when they were negatively stereotyped as 'unworthy', labeled as 'different', excluded from the decision-making process, discriminated against, 'treated unfairly', and felt powerless when interacting in the heath and dental care systems. Conversely, positive experiences were characterized by empathy, reassurance and good communication, which were empowering for patients. CONCLUSIONS: When associated with stigma, mental illness and addictions have negative implications for accessing health and dental care. From our participants' perspectives, it seems that the lack of understanding about their life conditions by the healthcare professionals was the origin of stigma. We suggest that an increased social awareness of these health issues be enhanced among current and future health and dental care professionals to help improve care experiences for this marginalized population.

Scrambled eyes? Disrupting scene structure impedes focal processing and increases bottom-up guidance.

Previous research has demonstrated that search and memory for items within natural scenes can be disrupted by "scrambling" the images. In the present study, we asked how disrupting the structure of a scene through scrambling might affect the control of eye fixations in either a search task (Experiment 1) or a memory task (Experiment 2). We found that the search decrement in scrambled scenes was associated with poorer guidance of the eyes to the target. Across both tasks, scrambling led to shorter fixations and longer saccades, and more distributed, less selective overt attention, perhaps corresponding to an ambient mode of processing. These results confirm that scene structure has widespread effects on the guidance of eye movements in scenes. Furthermore, the results demonstrate the trade-off between scene structure and visual saliency, with saliency having more of an effect on eye guidance in scrambled scenes.
