Symptoms, Traits, and Disorders (STanD) Study

We are inviting participants who are 18 years or older and fluent in English to participate in the STanD (Symptoms, Traits, and Disorders) study, which examines mood, anxiety, and other symptoms, as well as personality traits. Participation requires a 3-hour visit to our lab at 501 N. Hill Street, South Bend, IN 46617 and will include completing several self-report questionnaires and interviews. All the information you provide will be kept confidential. Compensation is provided.  Please email ndstudy@nd.edu or call us at (574-631-2930) to learn more about the study and enrollment.

 

Note: This study is different from RAPS, which ran from December 2012 to May 2014, PEP, which ran from August 2014 to December 2016, and IMPP. See descriptions of these studies below. If you participated in one of our earlier studies, you may still eligible to participate in future studies.

 

IMPP — no longer recruiting
Improving the Measurement of Personality Project (IMPP) was a 6-year project ​​​​​​funded by a grant from the National Institute of Mental Health to Professor Clark to develop a new system to diagnose personality pathology, commonly known as personality disorder.  The system includes assessment of both personality traits and personality functioning. Research participants completed interviews and surveys at our Center twice, 6-12 months apart to examine how stable their personalities were over time. We also collected data from informant—one or two people who knew our participants well.  Data collection ended in late 2016, we have begun to publish the results, and we have many more papers planned.

 

PEP — no longer recruiting
​​​​​​The Positive Emotionality and Psychopathology (PEP) study examined relations between personality—which was assessed using the NEO Personality Inventory-3—and disorders reflecting either anhedonia (e.g., major depression, social anxiety) or excessive reward seeking (e.g., mania, narcissistic personality disorder). PEP included three types of data: (1) participant self-ratings, (2) informant ratings, and (3) clinical interviews using the Mini-International Neuropsychiatric Interview (M.I.N.I.) and the Structured Interview for DSM-IV Personality (SIDP-IV).  Data collection was completed in 2016; the data currently are being prepared for publication.

 

RAPS — no longer recruiting
The ​​​​​​Relations among Personality and Symptoms (RAPS) study examined associations between several hierarchical trait measures—including the NEO Personality Inventory-3, the Faceted Inventory of the Five-Factor Model, and the Revised HEXACO Personality Inventory—and a very broad range of psychopathological symptoms and diagnoses.  The psychopathology measures included indicators of mania, depression, anxiety, obsessive-compulsive and related disorders, posttraumatic stress disorder, psychosis, substance use, and personality pathology.  Data collection was completed in 2014.  The RAPS dataset has been used in multiple publications written by CAMPP lab members.
