Introduction:
The science of team science (SciTS) is an emerging research area that studies the processes and outcomes of team-based research. A well-established conceptual framework and appropriate methodology for examining the effectiveness of team science are critically important for promoting and advancing collaborative and interdisciplinary research. Although many instruments have been developed and used in the SciTS field, psychometric evidence has not been routinely assessed or reported for these scales. In addition, commonly used psychometric methods were mainly limited to internal consistency and factor analysis. To fill the gaps, this study introduces a framework based on Rasch measurement theory for creating and evaluating measures for team sciences.
Methods:We illustrate the application of Rasch measurement theory through the creation of valid measures to evaluate the processes of interdisciplinary scientific teams. Data were collected from 16 interdisciplinary teams through a university-wide initiative for promoting interdisciplinary team collaboration. Psychometric evidence based on a many-facet Rasch model was obtained for assessing the quality of the measures.
Results:The interdisciplinary teams differed in their clarity measures. Significant differences were also found between gender groups, racial groups, and academic ranks. We reported the reliability of measures and identified items that do not fit the model and may present potential threat to validity and fairness of SciTS measures.
Conclusion:This study shows the great potential of using Rasch measurement theory for developing and evaluating SciTS measures. Applying Rasch measurement theory produces objective measures that are comparable across individuals, interdisciplinary teams, institutions, time, and various demographic groups.

Introduction:
Incentivizing the development of interdisciplinary scientific teams to address significant societal challenges usually takes the form of pilot funding. However, while pilot funding is likely necessary, it is not sufficient for successful collaborations. Interdisciplinary collaborations are enhanced when team members acquire competencies that support team success.
Methods:We evaluated the impact of a multifaceted team development intervention that included an eight-session workshop spanning two half-days. The workshop employed multiple methods for team development, including lectures on empirically supported best practices, skills-based modules, role plays, hands-on planning sessions, and social interaction within and across teams. We evaluated the impact of the intervention by (1) asking participants to assess each of the workshop sessions and (2) by completing a pre/postquestionnaire that included variables such as readiness to collaborate, goal clarity, process clarity, role ambiguity, and behavioral trust.
Results:The content of the team development intervention was very well received, particularly the workshop session focused on psychological safety. Comparison of survey scores before and after the team development intervention indicated that scores on readiness to collaborate and behavioral trust were significantly higher among participants who attended the workshop. Goal clarity, process clarity, and role ambiguity did not differ among those who attended versus those who did not.
Conclusions:Multicomponent team development interventions that focus on key competencies required for interdisciplinary teams can support attitudes and cognitions that the literature on the science of team science indicate are predictive of success. We offer recommendations for the design of future interventions.

Background
Othello syndrome, also known as morbid jealousy, pathological jealousy, and conjugal paranoia, is a rare delusional disorder related to partner’s infidelity. There are no large scale or comprehensive studies on delusional jealousy, and only few case reports and cases series leave delusional disorder jealous type (DDJT) largely unknown. Herein, we report a case of DDJT, its possible etiology and describe its characteristics, comorbidities, and interventions.
Case DescriptionA 65-year-old married, retired, and disabled Caucasian male with a history of closed traumatic brain injury and chronic pain presented for outpatient care accompanied by his wife with a chief complaint of paranoid delusions. The patient was a car racer when he sustained over 25% total body surface area burns after his motor vehicle crashed at the speed of almost 160 mph. The patient was in a coma for more than nine weeks, coded three times, and was resuscitated each time. Per imaging, the patient suffered subarachnoid hemorrhage to the right outer parietal and left front parietal lobes. The patient developed chronic pain from the extensive burns and has been on opioids for many years until he gradually tapered himself off about six years ago. For the last couple of years, the patient has experienced cognitive decline associated with disorientation and memory deficit. The patient has been perseverative on his wife’s trip two years ago during which the patient believed that she had an affair with one of their mutual acquaintances. The patient denied visual or auditory hallucinations and continued to express his love and affection toward his wife. Although his wife has continually provided reassurance, and multiple family members confirmed her faithfulness, the patient had minimal insight into his delusion and expressed disappointment in loss of sexual intimacy between him and his wife. The patient has been prescribed duloxetine 60mg and trazodone 150mg, and his mood, anxiety, and sleep have been stable. The patient has also started taking pimozide 1mg nightly since beginning of this year with good response.
DiscussionThe DSM estimates the prevalence of DDJT to be less than 1%. At least a third of cases show neurological basis involving frontal lobe dysfunction associated with strokes, Parkinson’s disease, brain trauma and tumors, neurodegenerative disorder, encephalitis, multiple sclerosis, and even normal pressure hydrocephalus. Association with alcohol, amphetamine, cocaine, and dopamine therapy (pergolide, ropinirole, levodopa, amantadine, and pramipexole) were reported. Finally, DDJT is known to be a risk factor of violent crimes including homicide. Treatment with pimozide shows the strongest evidence, and most patients show improvement with any antipsychotic medication along with CBT. Continued research and further clinical trials are warranted for DDJT considering patients’ positive response to interventions, and because DDJT can become a dangerous condition in forensic situations.
