Distress in EMSworkers. The Journal consulting and Clinical Psychology reported on a study of emergency service (EMS) rescue workers who responded to the I-880 freeway collapse during a San Francisco earthquake. The goal of the study was to identify the predictors of symptomatic distress in the EMS workers. One of the distress variables studied was the Global Symptom Index (GSI). Several models for GSI, y, were considered based on the following independent variables: x1 = Critical Incident Exposure scale (CIE) x2 = Hogan Personality Inventory—Adjustment scale (HPI-A) x3 = Years of experience (EXP) x4 = Locus of Control scale (LOC) x5 = Social Support scale (SS) x6 = Dissociative Experiences scale (DES) x7 = Peritraumatic Dissociation Experiences Questionnaire, self-report (PDEQ-SR) (a) Write a first-order model for E(y) as a function of the first five independent variables, x1 –x5. (b) The model of part a, fitted to data collected for n = 147 EMS workers, yielded the following results: R2 = .469,F = 34.47, p-value <.001. Interpret these results. (c) Write a first-order model for (y) as a function of all seven independent variables, x1 –x7. (d) The model, part c, yielded R2 = .603. Interpret this result. (e) The t-tests for testing the DES and PDEQ-SR variables both yielded a p-value of .001. Interpret these results

Given:
= Critical Incident Exposure scale (CIE)
= Hogan Personality Inventory—Adjustment scale (HPI-A)
= Years of experience (EXP)
= Locus of Control scale (LOC)
= Social Support scale (SS)
= Dissociative Experiences scale (DES)
= Peritraumatic Dissociation Experiences Questionnaire, self-report (PDEQ-SR)
