Laura
Summerfeldt
 My
general area of research is personality and psychopathology, with
a specific focus upon obsessive-compulsive characteristics in nonclinical
and clinical populations.
Other research interests include: a) Points of continuity among clinical and
subclinical obsessive-compulsive phenomena and adaptive behaviour; b) Models
of heterogeneity of obsessive-compulsive disorder; c) Personality dimensions
and psychopathology in clinical and nonclinical populations; and, d) Cognitive
characteristics of obsessive-compulsive disorder and other anxiety disorders
I received my doctorate in Psychology (Ph.D.) in 1998 from York University,
under the supervision of the late Norman S. Endler, Ph.D., and went on to complete
a postdoctoral fellowship in the Department of Psychiatry and Behavioural Neurosciences
at McMaster University, where I continue to hold an appointment as an adjunct
Assistant Professor.
In 2000, I began a full-time position as an Assistant Professor in the Department
of Psychology at Trent University. A principal area of research, currently
funded by a research grant from the Social Sciences and Humanities Research
Council of Canada (SSHRC), examines basic dimensions that may underlie the
many different types of obsessive-compulsive symptoms in both clinical and
nonclinical populations, with a focus on perfectionistic "just right" experiences.
I am a registered Clinical Psychologist. My clinical activities are located
at the Anxiety Treatment and Research Centre at St. Joseph's Hospital in Hamilton,
where I am involved in the assessment and cognitive-behavioral treatment of
obsessive-compulsive disorder and other anxiety disorders.
