“Normal” control subjects are hard to find: A model for centralized recruitment

Prevalence and clinical significance of lymphocytic foci in minor salivary glands of healthy volunteers

“…Another possible reason for the finding of focal sialadenitis could be selection bias in the recruitment of healthy volunteers. Schechter et al (25) pointed out that it might be difficult to find truly healthy control subjects. People who have concerns about the disorder of interest may volunteer as healthy control subjects to get a free examination and consultation.…”

Quality of life of ‘normal’ controls: Association with lifetime history of mental illness

“…A description of the recruitment and assessment procedures for the CRP is included in this report. Additional information about this program can be found in previous reports (Schechter et al, 1994(Schechter et al, , 1998Schechter and Lebovitch, 2005). The protocol was begun after IRB approval was obtained.…”

Self-concept structure and borderline personality disorder: Evidence for negative compartmentalization

“…Thus, we hypothesize that patients with BPD exhibit more compartmentalized self-concepts than non-clinical individuals. Although one finding with nonclinical students appears to suggest that borderline personality features are unrelated to compartmentalization (Showers et al, 2006), findings from studies using non-clinical samples might not be an appropriate proxy for a clinical sample of patients diagnosed with BPD (Schechter, Strasser, Santangelo, Kim, & Edicott, 1994). For instance, BPD patients may differ from non-clinical controls on both quantitative and qualitative levels.…”
