Simulated Sea Surface Salinity Data from a 1/48° Ocean Model.

To study the validation process for sea surface salinity (SSS) we have generated one year (November 2011- October 2012) of simulated satellite and in situ "ground truth" data. This was done using the ECCO (Estimating the Circulation and Climate of the Oceans) 1/48° simulation, the highest resolution global ocean model currently available. The ground tracks of three satellites, Aquarius, SMAP (Soil Moisture Active Passive) and SMOS (Soil Moisture and Ocean Salinity) were extracted and used to sample the model with a gaussian weighting similar to that of the spaceborne sensor ground footprint. This produced simulated level 2 (L2) data. Simulated level 3 (L3) data were then produced by averaging L2 data onto a regular grid. The model was sampled to produce simulated Argo and tropical mooring SSS datasets. The Argo data were combined into a simulated gridded monthly 1° Argo product. The simulated data produced from this effort have been used to study sampling errors, matchups, subfootprint variability and the validation process for SSS at L2 and L3.

Give until It Hurts: An Exploratory Analysis of Mental Health Workers' Wellness.

BACKGROUND: The well-being of mental health professionals has been of growing concern due to the increasing rates of reported stress and burnout. Previous research suggests that the quality of life for mental health workers (MHWs) is at an increased risk due to clinical load, salary concerns, and lack of time for self-care activities outside of work. There is a lack of research regarding the wellness of MHWs (i.e., psychology graduate students, academic faculty, psychiatrists, and mental health counselors) and its relation to the workplace environment. This study examined job-related factors that impacted participants' social, emotional, and professional well-being. METHODS: Participants were recruited via professional organization listservs and answered questions about their psychological health (Generalized Anxiety Disorder-7 and Patient Health Questionnaire-9), support systems (Multidimensional Scale of Perceived Social Support), and three qualitative questions about what they enjoy or find challenging about their work and any barriers to engaging in self-care activities. RESULTS: An inductive qualitative analysis of the qualitative questions and descriptive statistics are presented to provide context for their qualitative responses. CONCLUSIONS: Institutions can better support their workers by creating outlets to teach their staff self-care strategies and practice these strategies at work.

Moderate-Affinity Affibodies Modulate the Delivery and Bioactivity of Bone Morphogenetic Protein-2.

Uncontrolled bone morphogenetic protein-2 (BMP-2) release can lead to off-target bone growth and other adverse events. To tackle this challenge, yeast surface display is used to identify unique BMP-2-specific protein binders known as affibodies that bind to BMP-2 with different affinities. Biolayer interferometry reveals an equilibrium dissociation constant of 10.7 nm for the interaction between BMP-2 and high-affinity affibody and 34.8 nm for the interaction between BMP-2 and the low-affinity affibody. The low-affinity affibody-BMP-2 interaction also exhibits an off-rate constant that is an order of magnitude higher. Computational modeling of affibody-BMP-2 binding predicts that the high- and low-affinity affibodies bind to two distinct sites on BMP-2 that function as different cell-receptor binding sites. BMP-2 binding to affibodies reduces expression of the osteogenic marker alkaline phosphatase (ALP) in C2C12 myoblasts. Affibody-conjugated polyethylene glycol-maleimide hydrogels increase uptake of BMP-2 compared to affibody-free hydrogels, and high-affinity hydrogels exhibit lower BMP-2 release into serum compared to low-affinity hydrogels and affibody-free hydrogels over four weeks. Loading BMP-2 into affibody-conjugated hydrogels prolongs ALP activity of C2C12 myoblasts compared to soluble BMP-2. This work demonstrates that affibodies with different affinities can modulate BMP-2 delivery and activity, creating a promising approach for controlling BMP-2 delivery in clinical applications.

A systematic review of health-related quality of life outcomes in psychosocial intervention trials for adolescent and young adult cancer survivors.

BACKGROUND: The National Cancer Institute has catalyzed research in adolescent and young adult (AYA) oncology by identifying the need for supportive care intervention studies and psychometrically robust health-related quality of life (HRQOL) measures. We evaluated progress toward these goals (1) examining changes in the number of registered psychosocial intervention trials being conducted with AYAs over time; (2) determining what domains of HRQOL were assessed across these intervention trials; and (3) identifying the most frequently used measures of HRQOL. METHODS: We conducted a systematic review of psychosocial intervention trials for AYAs registered on ClinicalTrials.gov from 2007 to 2021. Following identification of relevant trials, we extracted the outcome measures and determined whether they were measures of HRQOL and which HRQOL domains were evaluated. Descriptive statistics were used to summarize trial and outcome characteristics. RESULTS: We identified 93 studies that met our inclusion criteria and 326 HRQOL outcomes across studies. The average number of clinical trials conducted annually has increased from 2 (SD = 1) during the years of 2007-2014 to 11 (SD = 4) during the years of 2015-2021. 19 trials (20.4%) did not include a measure of HRQOL. HRQOL measures varied widely, and most evaluated psychological and physical domains. Of the 9 measures used 5 + times, none were developed to cover the full AYA age spectrum. CONCLUSIONS: This review demonstrated that the number of AYA psychosocial intervention trials conducted annually has increased. However, it also revealed several important areas for additional work including: (1) ensuring psychosocial trials include HRQOL measures; (2) increasing the frequency of evaluation of underrepresented domains of HRQOL (e.g., body image, fertility/sexuality and spiritual); and (3) improving the validity and standardization of measures used to evaluate domains of HRQOL across AYA-focused trials to improve the field's ability to compare the impact of different psychosocial interventions on HRQOL outcomes.

Interactions between FUS and the C-terminal Domain of Nup62 are Sufficient for their Co-phase Separation into Amorphous Assemblies.

Deficient nucleocytoplasmic transport is emerging as a pathogenic feature of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD), including in ALS caused by mutations in Fused in Sarcoma (FUS). Recently, both wild-type and ALS-linked mutant FUS were shown to directly interact with the phenylalanine-glycine (FG)-rich nucleoporin 62 (Nup62) protein, where FUS WT/ Nup62 interactions were enriched within the nucleus but ALS-linked mutant FUS/ Nup62 interactions were enriched within the cytoplasm of cells. Nup62 is a central channel Nup that has a prominent role in forming the selectivity filter within the nuclear pore complex and in regulating effective nucleocytoplasmic transport. Under conditions where FUS phase separates into liquid droplets in vitro, the addition of Nup62 caused the synergistic formation of amorphous assemblies containing both FUS and Nup62. Here, we examined the molecular determinants of this process using recombinant FUS and Nup62 proteins and biochemical approaches. We demonstrate that the structured C-terminal domain of Nup62 containing an alpha-helical coiled-coil region plays a dominant role in binding FUS and is sufficient for inducing the formation of FUS/Nup62 amorphous assemblies. In contrast, the natively unstructured, F/G repeat-rich N-terminal domain of Nup62 modestly contributed to FUS/Nup62 phase separation behavior. Expression of individual Nup62 domain constructs in human cells confirmed that the Nup62 C-terminal domain is essential for localization of the protein to the nuclear envelope. Our results raise the possibility that interactions between FUS and the C-terminal domain of Nup62 can influence the function of Nup62 under physiological and/or pathological conditions.

Properties of the Shift and Persist Questionnaire in adolescent and young adult cancer patients and survivors: Validity, consistency, and interpretability.

PURPOSE: The Shift and Persist model provides an informative framework to understand how adolescent and young adult (AYA) cancer patients and survivors (ages 15-39) may withstand stress and thrive despite adversity. The goal of the present study was to examine the psychometric properties of the Shift and Persist Questionnaire (SPQ) in this population and provide guidelines for interpretation. METHODS: AYA cancer patients and survivors were recruited via an online research panel. Participants reported demographics and health history and completed the SPQ and Patient-Reported Outcome Measurement Information System 29-item profile (PROMIS®-29). We evaluated the structural validity, internal consistency, and construct validity of the SPQ. Minimally important differences (MIDs) were estimated to inform SPQ score interpretation. RESULTS: 572 eligible individuals completed the survey. On average, participants were aged 24 (SD = 7) at evaluation. Of the participants, 43.5% were female, 77.1% were white, and 17.5% were Hispanic (across races). The two-factor structure of the SPQ demonstrated very good structural validity (CFI > 0.95, SRMR < 0.08), and construct validity with PROMIS-29® domains (convergent Rs = 0.17 to 0.43, divergent Rs = - 0.11 to - 0.51). Internal consistency was adequate (ω = 0.76-0.83). Recommended MIDs were 1 point for the Shift subscale, 1-2 point(s) for the Persist subscale, and 2-3 points for the total SPQ score. CONCLUSION: The SPQ is a psychometrically sound measure of skills that contribute to resilience in AYA cancer patients and survivors. MID recommendations enhance the interpretability of the SPQ in this population. Future studies examining shifting and persisting in this population may benefit from administering the SPQ.

Effect of slit lamp table design on neck position and the prevalence of neck pain in eye care professionals.

BACKGROUND: Ophthalmologists/Optometrists have a high incidence of neck pain. Little research has been conducted on specific equipment that predisposes these professionals to cervical discomfort. OBJECTIVE: Primary purpose: to determine if neck position is altered by slit lamp table design. Secondary purpose: to confirm the prevalence of neck pain in eye care professionals. METHODS: A survey of work-related pain was administered to 36 subjects (8 ophthalmologist, 2 optometrists, 26 technicians). The craniovertebral (CV) angle was measured in each subject in three separate positions (resting posture, best posture, slit lamp posture) between two different slit lamps/tables: slit lamp-deep and slit lamp-shallow. RESULTS: 79% of subjects reported neck pain in the last 6 months. The mean CV angle of all subjects at resting posture, best posture, and both slit lamp postures differed significantly. There was also a difference in CV angle between slit lamps. CONCLUSION: Neck pain is more prevalent in eye professionals than in the general population. The use of slit lamps promotes a forward head posture which decreases the CV angle, putting the user at risk for neck pain. By altering slit lamp table design, the CV angle of eye care professionals can be increased, reducing the risk for neck injury.

Preliminary Effects of Mindfulness Training on Inflammatory Markers and Blood Pressure in Young Adult Survivors of Cancer: Secondary Analysis of a Pilot Randomized Controlled Trial.

BACKGROUND: This was a secondary analysis of a pilot randomized controlled trial (RCT) of mindfulness-based stress reduction (MBSR) among young adult (YA) survivors of cancer, which showed preliminary evidence for improving psychosocial outcomes. Secondary outcomes assessed were the feasibility of collecting biological data from YAs and preliminary effects of MBSR on markers of inflammation and cardiovascular function. METHOD: Participants were randomized to 8-week MBSR or a waitlist control condition. Participants provided whole blood spot samples for analysis of C-reactive protein (CRP) and interleukin (IL)-6 as well as blood pressure data in-person at baseline and 16-week follow-up. Feasibility was assessed with rates of providing biological data. Linear mixed effects modeling was used to evaluate preliminary effects of MBSR on inflammatory markers and blood pressure over time. RESULTS: Of 126 total participants enrolled, 77% provided biological data at baseline (n = 48/67 MBSR, n = 49/59 control). At 16 weeks, 97% of the 76 retained participants provided follow-up biological data (n = 34/35 MBSR, n = 40/41 control). Relative to the control group, MBSR was associated with decreased systolic blood pressure (p = 0.042, effect sizes (ES) = 0.45) and decreased diastolic blood pressure (p = 0.017, ES = 0.64). There were no changes in CRP or IL-6. CONCLUSION: This was the first study to explore the feasibility of collecting biological data from YA survivors of cancer and assess preliminary effects of MBSR on inflammatory and cardiovascular markers in an RCT. Minimally invasive biological data collection methods were feasible. Results provide preliminary evidence for the role of MBSR in improving cardiovascular outcomes in this population, and results should be replicated.

Opposing Roles of the Dorsolateral and Dorsomedial Striatum in the Acquisition of Skilled Action Sequencing in Rats.

The shift in control from dorsomedial to dorsolateral striatum during skill and habit formation has been well established, but whether striatal subregions orchestrate this shift cooperatively or competitively remains unclear. Cortical inputs have also been implicated in the shift toward automaticity, but it is unknown whether they mirror their downstream striatal targets across this transition. We addressed these questions using a five step heterogeneous action sequencing task in male rats that is optimally performed by automated chains of actions. By optimizing automatic habitual responding, we discovered that loss of function in the dorsomedial striatum accelerated sequence acquisition. In contrast, loss of function in the dorsolateral striatum impeded acquisition of sequencing, demonstrating functional opposition within the striatum. Unexpectedly, the mPFC was not involved; however, the lateral orbitofrontal cortex was critical. These results shift current theories about striatal control of behavior to a model of competitive opposition, where the dorsomedial striatum interferes with the development of dorsolateral-striatum dependent behavior.SIGNIFICANCE STATEMENT We provide the most direct evidence to date that the dorsomedial and dorsolateral striatum compete for control in the acquisition of habitual action sequences. The dorsolateral striatum was critical for sequencing behavior, but loss of dorsomedial striatum function enhanced acquisition. In addition, we found that the mPFC was not required for the formation of automated actions. Using a task that optimizes habitual responding, we demonstrate that the arbitration of dorsomedial and dorsolateral control is not modulated by medial prefrontal cortical activity. However, we find evidence for the role of the lateral orbitofrontal cortex in action sequencing. These results have implications for our understanding of how habits and skills form.

The Development of iManage-PC, an Online Symptom Monitoring and Self-management Tool for Men With Clinically Localized Prostate Cancer.

BACKGROUND: Prostate cancer (PC) often impacts 4 major aspects of health-related quality of life (HRQL): urinary, sexual, and bowel dysfunction, and anxiety. Online tools may be helpful in supporting the development of self-management skills that can improve HRQL. OBJECTIVE: The aim of this study was to develop and pilot-test an online symptom monitoring and self-management program, iManage-PC. METHODS: A literature search, input from experts, and feedback from patients were used to develop iManage-PC. A 4-week, single-arm pilot study was conducted with 96 men with prostate cancer. We evaluated system usability, acceptance, and satisfaction and examined preliminary effects on patient-reported outcomes. RESULTS: Rates of retention (94.8%) and adherence to symptom monitoring (95.0%-97.0%) were high. Most participants rated the tool as satisfactory and acceptable (81.2%-94.3%). Related-samples Wilcoxon signed rank tests revealed that participants reported increased self-efficacy related to their ability to manage their adverse effects (T = 1772.0, P < .001, r = 0.39), physical discomfort (T = 1259.0, P < .001, r = 0.40), and stress and worry (T = 1108.5, P = .001, r = 0.34). Global mental and physical health also improved (T = 1322.0, P = .032, r = 0.23, and T = 1409.0, P = .001, r = 0.35, respectively). CONCLUSIONS: Future research with such tools should examine the potential role of cut-score-derived management interventions to improve engagement, symptom management self-efficacy, and HRQL. IMPLICATIONS FOR PRACTICE: Our findings are consistent with a growing body of literature that supports the feasibility and acceptability of remotely delivered interventions.

Inclusion of Patient-Reported Outcomes in Adolescent and Young Adult Phase III Therapeutic Trials: An Analysis of Cancer Clinical Trials Registered on ClinicalTrials.gov.

OBJECTIVES: There is a paucity of research on the impact of cancer treatment on the health-related quality of life (HRQOL) of adolescent and young adult (AYA) patients with cancer. Patient-reported outcomes (PROs) are self-report measures used to assess HRQOL and symptom burden. The extent to which PROs have been included in trials that include common AYA cancer types has not been previously assessed. METHODS: Therapeutic phase 3 trials among common AYA cancer types (Hodgkin lymphoma, non-Hodgkin lymphoma, acute lymphoblastic leukemia, sarcomas, and germ cell tumors) initiated between 2007 and 2020 were identified on ClinicalTrials.gov. The proportions and characteristics of trials including a PRO endpoint were assessed. For comparison with an older population, the proportion of breast and colorectal therapeutic phase 3 trials including PRO endpoints were assessed. RESULTS: Eighty-seven studies met the inclusion criteria. Overall, 20.7% of therapeutic phase 3 AYA trials included a PRO endpoint, and only one trial published PRO data. Germ cell tumors (42.9%) and non-Hodgkin lymphoma (40%) trials had the highest proportions of PRO inclusion. The European Organization for Research and Treatment of Cancer generic, cancer-specific quality of life questionnaire was the most commonly used PRO measure; nevertheless, the measures used varied within and between cancer types. The proportion of trials including a PRO endpoint did not change significantly between 2007 to 2013 and 2014 to 2020 (18.6% vs 22.7%, P=.79). CONCLUSIONS: Few therapeutic phase 3 AYA cancer trials include PRO endpoints, fewer publish PRO data, and there is no homogeneity in the measures administered. Therapeutic trials represent an underused opportunity to capture PRO data in the AYA population with the goal of improving HRQOL outcomes.

Clinical Effectiveness of an Outpatient Multidisciplinary Chronic Pain Management Telementoring Service.

OBJECTIVE: The objective of this study was to assess the effectiveness of a Pain E-Consult Program (PEP), a multidisciplinary telementoring service based on the Extension for Community Healthcare Outcomes (ECHO) model to reduce opioid use in the outpatient setting. MATERIALS AND METHODS: This was a retrospective matched cohort study conducted in an integrated health care delivery system. Adult patients without cancer and with a 90-day morphine milligram equivalent (MME) ≥30 mg/d between April 1, 2016, and June 30, 2017, were included. Patients whose primary care clinician received the PEP (observation) were compared with usual care (control) patients. Observation patients were matched up to 1:5 to control patients. Outcomes included change in MME and initiation of nonopioid alternative medications. Multivariable regression analyses were performed. RESULTS: A total of 665 patients were matched: 125 and 540 in the observation and control groups, respectively. Patients were primarily female, white, and Medicare beneficiaries. The observation group had a statistically significantly greater decrease in median MME/day during the 6-month (-7.4 vs. 1.5 mg, P=0.002) and 12-month (-15.1 vs. -2.8 mg, P<0.001) follow-up and rates of ≥20% decrease (6 mo: 41.6% vs. 24.6%, P=0.003; 12 mo: 48.0% vs. 32.6%, P=0.017). There were no differences in the rates of initiation of nonopioid alternative medications. CONCLUSIONS: A PEP was associated with greater reductions in MME/day compared with usual care despite similar rates of nonopioid alternative medication initiation. A prospective randomized study of this program should be undertaken to confirm these findings.

Does disrupting the orbitofrontal cortex alter sensitivity to punishment? A potential mechanism of compulsivity.

Abnormal orbitofrontal cortex (OFC) activity is one of the most common findings from neuroimaging studies of individuals with compulsive disorders such as substance use disorder and obsessive-compulsive disorder. The nature of this abnormality is complex, however, with some studies reporting the OFC to be over-active in compulsive individuals relative to controls, whereas other studies report it being under-active, and a further set of studies reporting OFC abnormality in both directions within the same individuals. The OFC has been implicated in a broad range of cognitive processes such as decision-making and goal-directed action. OFC dysfunction could thus impair decision-making and goal-directed action, leading to the kinds of cognitive/behavioral deficits observed in individuals with compulsive disorders. One such deficit that could arise as a result of OFC dysfunction is an altered sensitivity to punishment, which is one of the core characteristics displayed by individuals across multiple types of compulsive disorders. It is, therefore, the aim of the current review to assess the evidence implicating the OFC in adaptation to punishment and to attempt to identify the critical factors that determine this relationship. We distill from this analysis some guidelines for future studies attempting to determine the precise role of the OFC in punishment. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

Consider the Source: Examining Attrition Rates, Response Rates, and Preliminary Effects of eHealth Mindfulness Messages and Delivery Framing in a Randomized Trial with Young Adult Cancer Survivors.

Purpose: Young adults with cancer often experience stress, depression, and anxiety. Mindfulness meditation is an effective intervention for these outcomes, and maintenance support may be needed for long-term improvements. eHealth technologies provide a promising delivery strategy for maintenance interventions. Methods: Following an 8-week mindfulness-based stress reduction (MBSR) course, 62 young adult cancer survivors were randomized to 8 weeks of instructor-framed messages, peer-framed messages, or no messages. On average, participants were 33.6 years old. The majority of participants were college-educated Caucasian females. We examined attrition rates between participants who received messages and those who did not, and compared response rates from different perceived sources. In addition, we evaluated the preliminary effects of eHealth support on mindfulness and associated outcomes. Results: No significant differences in attrition or message response rates across groups were observed. Repeated measures models revealed significant group by time interactions on perceived stress, anxiety, and depression. There were no differences between the groups that received eHealth messages and the group that did not. There was a significant difference in anxiety symptoms from post-MBSR to post-messaging between messaging groups. Individuals who received instructor-framed messages reported increased symptoms of anxiety over time. Conclusion: Attrition and response rates did not differ across groups, suggesting that eHealth may be a feasible strategy for providing maintenance support. However, further evaluation of feasibility, acceptability, and optimal content and dose of such an intervention is needed. Additionally, young adult cancer survivors may be more likely to benefit from eHealth interventions that are not delivered by authority figures.

Prefrontal regulation of behavioural control: Evidence from learning theory and translational approaches in rodents.

Everyday activities require adaptive decision-making and control over our actions to achieve our goals. Sub-regions within the cortex are widely reported to regulate these choices. Here we review rodent studies from two disparate fields of instrumental action control - goal-directed and habitual responding, and impulsive and compulsive behaviour. Our aim was to compare findings across the spectrum, from precision associative learning to translational studies of action control. The evidence suggests that each cortical sub-region performs different roles depending on task requirements and, within tasks, clear dissociations exist between regions. Rather than synthesizing a single role or function for a given region, we should consider regions to be capable of many different functions. Further investigation of cortico-cortical connections and the pattern of input and output circuitry within each region may be needed to identify unique process-specific pathways. Despite differences in the scope and purpose of these two fields, integrating evidence across tasks provides a broader context for testing hypotheses about the role of cortical regions in adaptive actions and decision-making.

Direct and Indirect Effects of Trait and State Gratitude on Health-Related Quality of Life in a Prospective Design.

Gratitude has been consistently linked to well-being, but its influence on health-related functioning is not well understood. Furthermore, research suggests the need to differentiate between-person and within-person effects of personality characteristics, and research on gratitude and health has not typically done so. This prospective study aimed to (1) differentiate the unique effects of trait and state gratitude on health-related quality of life (HRQoL) and (2) test state gratitude as a mediator between baseline trait gratitude and subsequent HRQoL. Undergraduate participants (N = 141) completed a trait gratitude measure at baseline and then repeated measures of weekly state gratitude and HRQoL over eight weeks. Multilevel models examined baseline trait gratitude, state gratitude averaged across the study (person aggregate) as between-person individual differences, and within-person variability in state gratitude (person-centered) as predictors of HRQoL, as well as the indirect effect of trait gratitude on HRQoL via state gratitude. Greater aggregate and person-centered state gratitude each predicted higher HRQoL. Baseline trait gratitude did not have a significant direct effect but prospectively predicted higher HRQoL via higher weekly state gratitude. Results suggest that understanding effects of gratitude on health-related perceptions requires accounting for both between-person individual differences and within-person fluctuation in state gratitude.

Shear wave elastography and Afirma™ gene expression classifier in thyroid nodules with indeterminate cytology: a comparison study.

PURPOSE: To compare shear wave elastography (SWE) and Afirma™ gene expression classifier (GEC) for diagnosis of malignancy in thyroid nodules (TNs) with Bethesda Classification (BC) III or IV indeterminate cytology. METHODS: This preliminary single-center prospective study was approved by the Institutional Review Board. We evaluated 151 consented patients with 151 indeterminate TNs (123 BC III, 28 BC IV) on fine-needle aspiration biopsy (FNAB). B-mode ultrasound, vascularity, and SWE were performed prior to FNAB. TN stiffness was measured as shear wave velocity (SWV) in meters per second (m/s). The stiffest area of the TN was selected for SWV measurement. GEC testing was performed with a second FNAB. Surgery was recommended for GEC-suspicious TNs, or GEC-benign TNs with two or more worrisome B-mode US features. RESULTS: Surgical pathology confirmed 31 malignant TNs. Among the GEC-suspicious group, 28 of 59 TNs were malignant. The SWV value of ≥3.59 m/s was the best cut-off for malignancy risk based on the receiver operating curve (ROC). Twenty-six malignant TNs had SWV ≥ 3.59 m/s. The sensitivity and specificity for SWV ≥ 3.59 m/s were 83.9 and 79.2%, respectively. Positive predictive value (PPV) was 51.0% and negative predictive value (NPV) was 95.0%. For the GEC-suspicious group, sensitivity, specificity, PPV, and NPV were 90.3, 74.2, 47.5, and 96.7%, respectively. In multivariate analysis, SWV and GEC-suspicious were significant predictors of malignancy, but B-mode features and vascularity were not. CONCLUSION: This preliminary study indicates that SWE and GEC are independent predictors of malignancy in TNs with BC III or IV.

Psychopathy and Deviant Workplace Behavior: A Comparison of Two Psychopathy Models.

Although psychopathy is an interpersonally harmful construct, few studies have compared different psycho athy models in predicting different types of workplace deviance. We examined how the Triarchic Psychopathy Model (TRI-PM) and the Self-Report Psychopathy-Short Form (SRP-SF) predicted deviant workplace behaviors in two forms: sexual harassment and deviant work behaviors. Using structural equations modeling, the latent factor of psychopathy was predictive for both types of deviant workplace behavior. Specifically, the SRP-SF signif cantly predicted both measures of deviant workplace behavior. With respect to the TRI-PM, meanness and disinhibition significantly predicted higher scores of workplace deviance and workplace sexual harassment measures. Future research needs to investigate the influence of psychopathy on deviant workplace behaviors, and consider the measures they use when they investigate these constructs.
