Psychosocial Factors Influencing Quality of Life Among Medical Students.

OBJECTIVE: This study investigated the influence of psychosocial factors on medical students' quality of life (QOL). METHODS: A total of 408 medical students participated in this study. We collected data on participants' sociodemographic details, symptoms of depression and Internet addiction, self-esteem, social support, and QOL. QOL was assessed using the World Health Organization Quality of Life-Abbreviated form, which has four domains (physical health, psychological health, social relationships, and environment). A stepwise multiple linear regression model was constructed to identify factors' independent impact on QOL. RESULTS: Higher levels of depression and Internet addiction were associated with lower scores in all domains of QOL, whereas higher levels of self-esteem and social support were associated with higher scores. Being in third-year versus first-year was associated with higher scores in the physical health and environment domains. Living alone or in dormitories, low or middle socioeconomic status, and insufficient or moderate pocket money were associated with lower scores in the environment domain. Additionally, female students displayed significantly lower scores for physical health, psychological health, and environment than male students, but not for social relationships. There were significant differences in certain domains of QOL due to sociodemographic factors. CONCLUSION: This study demonstrates the psychosocial factors influencing medical students' QOL. Educational strategies focusing on strengthening self-esteem and social support as well as preventing depression and Internet addiction may contribute to improving medical students' QOL.

The mediating roles of workplace support and ethical work environment in associations between leadership and moral distress: a longitudinal study of Canadian health care workers during the COVID-19 pandemic.

Introduction: The COVID-19 pandemic has resulted in heightened moral distress among health care workers (HCWs) worldwide. Past research has shown that effective leadership may mitigate potential for the development of moral distress. However, no research to date has considered the mechanisms by which leadership might have an influence on moral distress. We sought to evaluate longitudinally whether Canadian HCWs' perceptions of workplace support and ethical work environment would mediate associations between leadership and moral distress. Methods: A total of 239 French- and English-speaking Canadian HCWs employed during the COVID-19 pandemic were recruited to participate in a longitudinal online survey. Participants completed measures of organizational and supervisory leadership at baseline and follow-up assessments of workplace support, perceptions of an ethical work environment, and moral distress. Results: Associations between both organizational and supervisory leadership and moral distress were fully mediated by workplace supports and perceptions of an ethical work environment. Discussion: To ensure HCW well-being and quality of care, it is important to ensure that HCWs are provided with adequate workplace supports, including manageable work hours, social support, and recognition for efforts, as well as an ethical workplace environment.

In Their Own Words: What Do Healthcare Workers Want from Their Organization during the COVID-19 Pandemic?

Pandemics are associated with heightened distress among healthcare workers (HCWs). We report qualitative findings from a two-stage survey administered to HCWs at a large acute care hospital in Ontario during the COVID-19 pandemic to identify their concerns and wellness needs. Responses reflected HCWs' desires to be heard, protected, prepared, supported and cared for by the organization. HCWs' concerns were diverse and dynamic, reflecting the specific circumstances of their work and personal lives as well as the shifting landscape of the pandemic. We discuss implications for organizations seeking to promote and protect HCWs' psychological well-being and resilience during pandemics.

Seeing is believing: an exploration of what residents value when they receive feedback.

OBJECTIVE: The primary purpose of this paper is to report on psychiatry residents' perceptions of what is important when receiving feedback from evaluators. METHODS: In January 2018, as part of the Harvard South Shore Psychiatry Residency Training Program's (HSS) ongoing local quality improvement efforts to enhance the delivery and effectiveness of feedback that residents receive from faculty during training, the authors disseminated a survey to psychiatry residents (n = 31) at HSS. Residents rated the level of importance of 17 statements pertaining to the way feedback is delivered. Two open-ended prompts also allowed respondents to share examples of growth-oriented and unhelpful feedback they have received during residency. RESULTS: Twenty-seven residents responded (87% response rate). Eighty-one percent rated "the evaluator models the same behavior they're encouraging" as "extremely important" when receiving feedback. Many residents also rated the following survey items as "extremely important": "confidence in the evaluator's clinical and interpersonal skills" (63.0%), "amount of time the evaluator observed the resident" (51.9%), "there is a way to fix a performance deficit" (51.8%), and "specific feedback based off the resident's work" (48.1%). Conversely, only 11.1% of residents rated the feedback sandwich as "extremely important." CONCLUSIONS: Despite a small sample size, this project demonstrated that, when receiving feedback, the majority of psychiatry residents strongly value when evaluators model the targeted behavior. The feedback sandwich was least important to residents. This project underscores the importance of evaluators serving as role models in the context of feedback, and findings can be used in faculty development activities focused on feedback delivery best practices.

Neuropsychiatry and neuroscience education of psychiatry trainees: attitudes and barriers.

OBJECTIVE: The American Association of Directors of Psychiatric Residency Training (AADPRT) Task Force on Neuropsychiatry and Neuroscience Education of Psychiatry Residents was established in 2011 with the charge to seek information about what the field of psychiatry considers the core topics in neuropsychiatry and neuroscience to which psychiatry residents should be exposed; whether there are any "competencies" in this area on which the field agrees; whether psychiatry departments have the internal capacity to teach these topics if they are desirable; and what the reception would be for "portable curricula" in neuroscience. METHODS: The task force reviewed the literature and developed a survey instrument to be administered nationwide to all psychiatry residency program directors. The AADPRT Executive Committee assisted with the survey review, and their feedback was incorporated into the final instrument. RESULTS: In 2011-2012, 226 adult and child and adolescent psychiatry residency program directors responded to the survey, representing over half of all US adult and child psychiatry training directors. About three quarters indicated that faculty resources were available in their departments but 39% felt the lack of neuropsychiatry faculty and 36% felt the absence of neuroscience faculty to be significant barriers. Respectively, 64 and 60% felt that neuropsychiatry and psychiatric neuroscience knowledge were very important or critically important to the provision of excellent care. Ninety-two percent were interested in access to portable neuroscience curricula. CONCLUSIONS: There is widespread agreement among training directors on the importance of neuropsychiatry and neuroscience knowledge to general psychiatrists but barriers to training exist, including some programs that lack faculty resources and a dearth of portable curricula in these areas.

Decreasing inter-resident conflict by using computer-generated on-call schedules.

OBJECTIVE: Although significant attention has been paid to the number of hours worked by residents, little consideration has been given to how the hours are assigned. This project describes an alternative to having Chief Residents manually create on-call schedules. In order to enhance objectivity and transparency, reduce perceived inequities in the process, and reduce inter-resident conflict, Harvard South Shore Psychiatry Residency Training Program experimented with a computer-generated on-call schedule. METHOD: A locally written MATLAB script generated an on-call schedule for academic year (AY) 2012-2013. Measurements to assess the manual scheduling method (from AY 2011-2012) and the computer-generated method included the balance in the total number of hours assigned to individual residents; the number of call switches over two six-month periods; and survey of the residents' perception of fairness of the two scheduling methods and preferences. RESULTS: A retrospective analysis of the AY 2011-2012 Chief Resident-generated call schedule found a range of differences of up to 25.8% between total hours assigned to individual residents in a given year. In the AY 2012-2013 computer-generated schedule, the differences in total hours assigned were reduced to a maximum of 6.1%. There were 63% fewer call switches resulting from the computer-generated as compared to the Chief Resident-generated method. Resident survey response rate was 76%. Seventy-seven percent of resident respondents (N = 22) perceived the computer-generated method to be fairer, and 90.9% of residents preferred having a summary table of hours of call per resident. Residents perceived the computer-generated method as resulting in less inter-resident conflict. CONCLUSION: Methods for assigning duty hour schedules that are transparent, equitable, and require less Chief involvement may result in perceptions of greater fairness and less inter-resident conflict.

Working memory in schizotypal personality disorder: fMRI activation and deactivation differences.

BACKGROUND: Schizotypal personality disorder (SPD) is considered a schizophrenia spectrum disorder, sharing with schizophrenia cognitive, neuropsychological, epidemiological, and biological characteristics. Working memory may be one area of shared deficit, although to date, this is only the second study to investigate working memory in SPD using fMRI. METHODS: In a block-design fMRI study, fifteen antipsychotic-naïve SPD and sixteen healthy control subjects performed blocks of a 2back visual working memory task and 0back continuous performance task while undergoing whole-brain fMRI at 3T. Whole-brain analyses were performed for the 0back>rest (fixation baseline) and the 2back>0back contrasts (isolating the working memory component from the visual perception and attention component). Parameter estimates were extracted to determine whether observed differences were due to task-induced activation and/or deactivation. RESULTS: Activation differences emerged between the two groups, without differences in task performance. In the 0back task, SPD showed decreased task-induced activation of the left postcentral gyrus. In the 2back>0back contrast, HC showed greater task-induced activation of the left posterior cingulate gyrus, superior temporal gyrus, insula, and middle frontal gyrus. These differences were due to SPD subjects' decreased task-induced activation in the left posterior cingulate gyrus, and task-induced deactivation in the remaining regions. CONCLUSIONS: These findings suggest that compared to HC subjects, individuals with SPD may achieve comparable working memory performance. However, differences emerge at the level of functional neural activation, attributable to different task-induced activation and deactivation patterns. Such differential recruitment of neural resources may be beneficial, contributing to SPD subjects' ability to perform these tasks comparably to HC subjects.

Globally and locally reduced MRI gray matter volumes in neuroleptic-naive men with schizotypal personality disorder: association with negative symptoms.

IMPORTANCE: Some, but not all, previous magnetic resonance imaging studies have indicated smaller cortical and local gray matter volumes (GMVs) in men with schizotypal personality disorder (SPD) compared with healthy control (HC) subjects. Thus, there is need for a whole-brain comparison to resolve inconsistencies and provide hitherto generally absent data on the association between GMV and symptoms. OBJECTIVE: To use voxel-based morphometry to evaluate a large sample of neuroleptic-naive men with SPD compared with group-matched HC subjects on local and global GMV and to identify associations with symptoms, especially negative symptoms. Also, to determine whether age-related GMV reductions are greater in men with SPD than HC subjects, providing presumptive evidence on possible progression. DESIGN, SETTING, AND PARTICIPANTS: This naturalistic study involved 54 neuroleptic-naive men with SPD and 54 male HC subjects aged 18 to 55 years recruited from the community and scanned on the same 1.5-T GE magnetic resonance imaging scanner. Participants were group matched on age, socioeconomic status, handedness, and IQ. MAIN OUTCOME MEASURES: Cross-sectional voxel-based morphometry, GMV in subjects with SPD and HC participants, and the relationship to clinical symptoms. RESULTS: A voxelwise analysis showed participants with SPD had significantly smaller GMV in the left superior temporal gyrus and widespread frontal, frontolimbic, and parietal regions compared with HC subjects. Most of these regional volumes were strikingly and significantly correlated with negative symptoms: the more the volume reduction, the more negative symptoms. Global cortical GMV and most regional GMV showed significant negative relationships with age in both those with SPD and HC subjects, without any group by age interactions. CONCLUSIONS AND RELEVANCE: Men with SPD showed global and widespread smaller regional GMV. The regional structural abnormalities were correlated with the severity of a participant's negative symptoms. While the pattern of GMV loss is similar to that in schizophrenia, the similar patterns of HC-SPD age-related GMV reduction suggest that SPD showed no progressive GMV loss, pointing to an important difference in the biological mechanisms of SPD and schizophrenia.

Prosodic abnormalities in schizotypal personality disorder.

OBJECTIVE: Patients with schizophrenia speak with blunted vocal affect but little is known regarding the prosody of persons with schizotypal personality disorder (SPD). This work examined expressive prosody in SPD, its relationship to brain structure, and outlined a framework for measuring elements of prosody in clinical populations. METHODS: Twenty-eight antipsychotic-naïve SPD subjects were matched with 27 healthy comparison (HC) subjects. Subjects read aloud short sentences and responded to probes to record both predetermined and self-generated speech samples. Samples were analyzed acoustically (pause proportion, duration, attack, and pitch variability) and subjectively by raters (amount of pauses, degree of emotion portrayed, and how much they wanted to hear more from the subjects) on paragraph, sentence, word, word-fragment, and syllable levels. Alexithymia and ability to self-monitor behavior were compared between groups. The pars opercularis was manually traced on structural MRI data. RESULTS: SPD subjects' speech had significantly more pauses, was slower, had less pitch variability, and expressed less emotion than HC subjects. Pitch variability correlated with socio-economic status achievement. There was no difference between groups in left or right pars opercularis volumes. A statistically significant correlation suggested that smaller left pars opercularis volumes in SPD subjects correlated with more pauses and less emotion. SPD subjects reported more alexithymia and difficulty self-monitoring their behavior compared with controls. In SPD subjects the high alexithymia correlated with raters not wanting to hear more from them and SPD subjects' inability to modulate their social behavior correlated with their having fewer friends. Thus, the SPD subjects exhibited insight. CONCLUSIONS: SPD subjects displayed significant prosodic deficits that were measurable in speech samples as brief as a word-fragment. The determinants of these deficits are not known although these may include a dysfunctional pars opercularis. These data add to the nascent literature describing social cognition deficits in SPD.

Facial emotion recognition and facial affect display in schizotypal personality disorder.

BACKGROUND: Patients with schizophrenia have deficits in facial affect expression and detection that hinder social interactions. The goal of this study was to examine whether or not epidemiologically-related antipsychotic-naïve schizotypal personality disorder (SPD) subjects would have similar deficits as patients with schizophrenia. METHODS: Matched SPD and healthy comparison (HC) subjects were asked to identify the eight classic emotions (SPD N=55, HC N=67) and to discriminate gender. Subjects (SPD N=22, HC N=17) were also photographed while displaying the same emotional expressions. Raters scored the subjects' facial expressions along several dimensions. RESULTS: SPD subjects compared with HC were slower and less accurate in identifying facial expressions. This may have been driven by deficits in identifying gender. Although raters were able to identify correctly SPD and HC subjects' expressions equally well, raters found SPD subjects' facial expressions to be more odd, more ambiguous, and the subjects less attractive in general compared with HC subjects. Raters were less confident in their ability to correctly interpret SPD subjects' facial expressions and raters were less comfortable with the idea of spending time with the SPD subjects compared with HC subjects. CONCLUSIONS: SPD subjects face two hurdles in terms of daily social interactions. They have problems both in correctly interpreting others' facial expressions and in generating socially attractive and unambiguous facial expressions.

Factors in sensory processing of prosody in schizotypal personality disorder: an fMRI experiment.

INTRODUCTION: Persons diagnosed with schizophrenia demonstrate deficits in prosody recognition. To examine prosody along the schizophrenia spectrum, antipsychotic-naïve schizotypal personality disorder (SPD) subjects and healthy control subjects were compared. It was hypothesized that SPD subjects would perform more poorly; with cognitive and demographic factors contributing to the poor performance. The superior temporal gyrus (STG) was selected as the region-of-interest (ROI) given its known abnormalities in SPD and its important role in the processing of prosody. METHODS: SPD and healthy comparison (HC) subjects were matched on age, IQ, and parental social-economic status (PSES). Cognitive measures included the Speech Sound Perception Test (SSPT) to examine phonological processing (SPD=68, HC=74) and the Verbal Fluency task to examine executive functioning (SPD=129, HC=138). The main experiment was a novel fMRI task of prosody identification using semantically neutral sentences spoken with emotional prosody (SPD=16, HC=13). Finally, volumetric measurement of the superior temporal sulcus (STS), a key region for processing prosody, and partially overlapping with the STG, was performed (SPD=30, HC=30). RESULTS: Phonological processing and executive functioning were both impaired in SPD subjects compared with HC subjects. Contrary to the prediction, SPD subjects, as a group, were similar to HC subjects in terms of correctly indentifying the emotion conveyed and reaction time. Within the SPD group, prosody identification accuracy was influenced by executive functioning, IQ and perhaps PSES, relationships not found with HC subjects. Phonological perception aided prosody identification in both diagnostic groups. As expected, both groups activated the STG while performing the prosody identification task. However, SPD subjects may have been less "efficient" in their recruitment of STG neurons. Finally, SPD subjects demonstrated a trend toward smaller STS volumes on the left, particularly the lower bank. CONCLUSIONS: These data suggest that subtle differences between SPD and controls in phonological processing, executive functioning, IQ, and possibly PSES, contributed to difficulty in processing prosody for some SPD subjects.

Dichotic listening in schizotypal personality disorder: evidence for gender and laterality effects.

Verbal dichotic listening performance was examined in 42 right-handed men and women with DSM-IV-defined schizotypal personality disorder (SPD) and 68 right-handed controls. As expected, both male and female control groups showed a right ear advantage on a verbal dichotic listening task. Although SPD subjects in general had lower accuracy scores than comparison subjects, only male SPD subjects showed an abnormal left ear advantage that was specifically due to deficient right ear performance. The results suggest that left hemisphere temporal lobe structures may be particularly involved in male, but not female, SPD.

Shape abnormalities of caudate nucleus in schizotypal personality disorder.

BACKGROUND: Previously, we reported abnormal volume and global shape in the caudate nucleus in schizotypal personality disorder (SPD). Here, we use a new shape measure which importantly permits local in addition to global shape analysis, as well as local correlations with behavioral measures. METHODS: Thirty-two female and 15 male SPDs, and 29 female and 14 male normal controls (NCLs), underwent brain magnetic resonance imaging (MRI). We assessed caudate shape measures using spherical harmonic-point distribution model (SPHARM-PDM) methodology. RESULTS: We found more pronounced global shape differences in the right caudate in male and female SPD, compared with NCLs. Local shape differences, principally in the caudate head, survived statistical correction on the right. Also, we performed correlations between local surface deformations with clinical measures and found significant correlations between local shape deflated deformations in the anterior medial surface of the caudate with verbal learning capacity in female SPD. CONCLUSIONS: Using SPHARM-PDM methodology, we found both global and local caudate shape abnormalities in male and female SPD, particularly right-sided, and largely restricted to limbic and cognitive anterior caudate. The most important and novel findings were bilateral statistically significant correlations between local surface deflations in the anterior medial surface of the head of the caudate and verbal learning capacity in female SPD. By extension, these local caudate correlation findings implicate the ventromedial prefrontal cortex (vmPFC), which innervates that area of the caudate, and demonstrate the utility of local shape analysis to investigate the relationship between specific subcortical and cortical brain structures in neuropsychiatric conditions.

Auditory processing abnormalities in schizotypal personality disorder: an fMRI experiment using tones of deviant pitch and duration.

BACKGROUND: One of the cardinal features of schizotypal personality disorder (SPD) is language abnormalities. The focus of this study was to determine whether or not there are also processing abnormalities of pure tones differing in pitch and duration in SPD. METHODS: Thirteen neuroleptic-naïve male subjects met full criteria for SPD and were group-matched on age and parental socio-economic status to 13 comparison subjects. Verbal learning was measured with the California Verbal Learning Test. Heschl's gyrus volumes were measured using structural MRI. Whole-brain fMRI activation patterns in an auditory task of listening to tones including pitch and duration deviants were compared between SPD and control subjects. In a second and separate ROI analysis we found that peak activation in superior temporal gyrus (STG), Brodmann Areas 41 and 42, was correlated with verbal learning and clinical measures derived from the SCID-II interview. RESULTS: In the region of the STG, SPD subjects demonstrated more activation to pitch deviants bilaterally (p<0.001); and to duration deviants in the left hemisphere (p=0.005) (two-sample t). SPD subjects also showed more bilateral parietal cortex activation to duration deviants. In no region did comparison subjects activate more than SPD subjects in either experiment. Exploratory correlations for SPD subjects suggest a relationship between peak activation on the right for deviant tones in the pitch experiment with odd speech and impaired verbal learning. There was no difference between groups on Heschl's gyrus volume. CONCLUSIONS: These data suggest that SPD subjects have inefficient or hyper-responsive processing of pure tones both in terms of pitch and duration deviance that is not attributable to smaller Heschl's gyrus volumes. Finally, these auditory processing abnormalities may have significance for the odd speech heard in some SPD subjects and downstream language and verbal learning deficits.

Occipital lobe gray matter volume in male patients with chronic schizophrenia: A quantitative MRI study.

Schizophrenia is characterized by deficits in cognition as well as visual perception. There have, however, been few magnetic resonance imaging (MRI) studies of the occipital lobe as an anatomically defined region of interest in schizophrenia. To examine whether or not patients with chronic schizophrenia show occipital lobe volume abnormalities, we measured gray matter volumes for both the primary visual area (PVA) and the visual association areas (VAA) using MRI based neuroanatomical landmarks and three-dimensional information. PVA and VAA gray matter volumes were measured using high-spatial resolution MRI in 25 male patients diagnosed with chronic schizophrenia and in 28 male normal controls. Chronic schizophrenia patients showed reduced bilateral VAA gray matter volume (11%), compared with normal controls, whereas patients showed no group difference in PVA gray matter volume. These results suggest that reduced bilateral VAA may be a neurobiological substrate of some of the deficits observed in early visual processing in schizophrenia.
