Initial Psychometric Properties of the Experiences Questionnaire: Validation of a Self-Report Measure of Decentering
Section snippets
Participants and Procedures
Data were obtained from two samples (Sample 1 and 2) of students enrolled in Introduction to Psychology courses at a large, midwestern United States university and involved in that university’s mass testing procedure. All students received course credit in return for their participation. Sample 1 (n = 1,150) was composed of 765 females (66.5%) and 385 males (33.5%), with a mean age of 19.1 years (SD = 4.1). Sample 2 (n = 519) was composed of 335 females (64.5%) and 184 males (35.5%), with a mean age
Study 2: Examining the Concurrent Validity of Decentering to Related Constructs
Study 2 sought to examine the concurrent and discriminant validity of the decentering scale in relation to four theoretically meaningful constructs in a nonpatient sample where participants also underwent clinician assessment for current and lifetime psychopathology. The four concurrent validity measures selected were depressive rumination, which emerges from the response styles theory (Nolen-Hoeksema, 1998); experiential avoidance, which emerges from Acceptance and Commitment Therapy (ACT;
Hypotheses
The primary goal of Study 2 was to examine the relationship of decentering to depressive rumination, experiential avoidance, reappraisal, and emotion suppression. A secondary goal of the study was to examine the association of decentering to current or lifetime major depressive disorder. The first hypothesis (Hypothesis 1) was that decentering would demonstrate a significant positive correlation with cognitive reappraisal, and significant negative correlations with depressive rumination,
Study 3: Confirmatory Factor Analysis of the Experiences Questionnaire in a Clinical Sample
Study 3 sought to replicate and extend previous findings by evaluating both the factor structure and the clinical validity of the EQ in a sample of patients with remitted MDD. The factor solution derived following CFA in the second student sample was evaluated in a sample of patients with remitted MDD who were participants in, but had not yet commenced, a trial of MBCT. The clinical validity of the factor solution in the patient sample was assessed in two ways. First, levels of decentering in
