Psychological Assessment employs a battery of psychological tests (combined with a clinical interview, observation, and medical chart information) to attain a comprehensive, integrated, and detailed depiction of a person’s emotional, interpersonal, social, and cognitive abilities.
The Psychological Evaluation and Research Laboratory (PEaRL) is a clinical consultation service offering comprehensive psychological evaluations. Patients referred for PEaRL evaluations often have complex or confusing clinical presentations, a history of sub-optimal treatment response, and a possible comorbid medical condition.
PEaRL evaluations include psychological and neuropsychological instruments to provide a broad description of a patient’s intellectual, neuro-cognitive, and psychological functioning. While psychological assessment has many applications, PEaRL evaluations are clinically focused, and we do not provide educational (i.e., identification of learning disabilities), functional (i.e., disability determinations) or legal (i.e., forensic evaluations) evaluations.
PEaRL evaluations are specifically designed to answer important clinical questions such as differential diagnosis, prioritizing and tailoring treatment strategies, and progress monitoring. Our psychologists are specialists with extensive training and experience conducting psychological assessments. They collaborate with referring professionals to ensure that our evaluations address the specific concerns of each patient.
As a result, PEaRL evaluations aid clinicians by answering critical clinical questions while also providing unique insight into the neurocognitive and psychological bases of a patient’s difficulty.
We are committed to providing prompt service with most appointments being scheduled within 4-8 weeks and reports available four weeks after the completed evaluation. In addition to providing clinical service, the PEaRL has an active research program and is a major training resource for the Massachusetts General Hospital/Harvard Medical School pre-doctoral psychology internship program.
Treating professionals within the Mass General Brigham system can refer patients for a comprehensive psychological evaluation through EPIC.
In addition to conducting state-of-the art psychological assessments, the PEaRL is an active and productive research program.
Consistent with our mission to advance the effectiveness of psychological assessment, PEaRL research is focused on understanding the validity and utility of common psychological and neuropsychological instruments. To achieve this goal, we have created an IRB-approved database that currently contains over 1,450 completed assessment protocols.
This extensive database allows us to explore the relationship of assessment findings to important life events (e.g., psychological trauma, hospitalization, academic problems and suicide attempts). Through this database, we are actively exploring the validity and clinical value of common psychological tests, while also seeking to increase our understanding of important psychiatric conditions. Members of our group have extensive expertise in psychometrics, scale development and validation, as well as specialized knowledge in the assessment of psychopathology, personality functioning, and treatment outcomes.
Trainees have the opportunity to join our ongoing research projects or develop projects consistent with our research and clinical mission. Most of our recent trainees have had successful research experiences and have presented papers or posters at professional conferences or published research articles as part of their PEaRL training.
Current Research Projects
The SPECTRA Clinical Assessment Project
Empirically-based dimensional models of psychopathology are reshaping how psychopathology is conceptualized, classified and measured. Clinical psychological assessment could benefit greatly from the conceptual insights and technical advantages offered by these dimensional views of psychopathology. However, at present methodological and conceptual limitations inherent in traditional clinical assessment limit the translation of these important findings into clinical practice. The goal of the SPECTRA Project is to develop and refine a conceptual and methodological framework for applying a hierarchical dimensional model of psychopathology in traditional clinical psychological assessment.
The Social Cognition and Object Relations Scale-Global Rating Method (SCORS-G)
There is a growing need in psychological assessment to develop measures that can reliable quantify dynamic themes and constructs present in free response narrative data. The Social Cognition and Object Relations Scale-Global Rating Method (SCORS-G) is among the most commonly used clinician-rated measures to code object relational content via narrative material. Michelle B Stein, PhD, the leading expert on this measure, has published multiple research studies exploring the reliability and validity of SCORS-G ratings. She has also written a comprehensive text on the SCORS-G system covering scoring, interpretation and innovative methods of applying the SCORS-G to a wide range of clinical encounters.
The goal of her research is to refine and improve the SCORS-G, enhance clinical utility, and increase the range of clinical applications including psychological assessment. Please contact Michelle B Stein, PhD or visit SCORS-G.com for more information.
John H. Porcerelli, PhD, ABPP, and Laura A. Richardson, PhD, are collaborating on studying Thematic Apperception Test (TAT) narratives of defensive functioning in psychiatric patients. Defense mechanisms, which are similar to coping styles, are automatic implicit processes that attempt to maintain or restore psychological equilibrium when one experiences external and internal stressors. Studying how defenses interact with personality organization and neurocognitive function improves our understanding of the psychological processes that contribute to coping and functional efficiency in a wide range of life situations.
Exploring Meta-Cognition through Method Convergence
We are interested in exploring clinically useful information embedded within our standard clinical assessment tools, consisting of both performance-based and self-report measures of similar constructs. We are currently interested in how meta-cognition—people’s ability to accurately evaluate their strengths and limitations—may be demonstrated through utilization of standard clinical assessment tools.
Mass General Psychiatry Treatment Monitoring Program (Completed)
Maintain, monitor and analyze outcome data for all clinical services provided within and across the Mass General Department of Psychiatry.
Schwartz Outcome Scale (SOS-10) Project
The SOS-10 is a unique and highly versatile mental health outcomes measure. We maintain a growing SOS-10 database and engage in projects that expand the use and application of the scale.
