To test the utility of a new self-report measure of trauma in the immediate aftermath of sexual assault, 253 women were interviewed with the 32-item Sexual Assault Symptom Scale (SASS) in a hospital emergency room within 72 hr of assault. Factor analysis with oblique rotation yielded a simple structure with 4 common factors: Disclosure Shame, Safety Fears, Depression, and Self-Blame. Cronbach alpha coefficients indicated high internal consistency for each factor subscale. Intercorrelalions between factor scores of the victims' self-report symptoms and assessments by crisis workers suggest that the SASS has construct validity, as a multitrait-multimcthod matrix demonstrated both convergent and discriminant validity.Extensive research has been conducted on the sexual assault trauma syndrome (SATS) and variables affecting recovery (for recent reviews of this literature, see Burgess & Holmstrom, 1985;Ruch & Leon, 1986;Sales, Baum, & Shore, 1984). Early studies measured trauma fairly crudely in terms of the presence or absence of symptoms (e.g., Holmstrom & Burgess, 1975; McCombie, 1976), but measurement has become increasingly rigorous in recent years as researchers (e.g., Becker, Skinner, & Abel, 1983;Kilpatrick, Veronen, & Best, 1985) have used standardized psychological assessment instruments, such as the Beck Depression Inventory (Beck, 1978) and the revised Symptoms Checklist-90 (SCL-90-R;Derogatis, 1977).A few studies have used scales developed for sexual assault victims. Kilpatrick, Veronen, and Resick (1979) developed the 120-item Veronen-Kilpatrick Modified Fear Survey (MFS) to measure self-reported fear. Content analysis of data on 46 victims and 35 nonvictims yielded three types of fears; Rape Cues, Rape-Precipitated Fears, and Attack Vulnerability Cues. Victims scored higher than nonvictims on all three dimensions in the first month but only on Vulnerability Cues at later assessments. Resick, Veronen, Calhoun, Kilpatrick, and Atkeson
