State Trait Anxiety Inventory (STAI)  -

The State-Trait Anxiety Inventory (STAI) is a commonly used measure of trait and state anxiety (Spielberger, Gorsuch, Lushene, Vagg, & Jacobs, 1983). It can be used in clinical settings to diagnose anxiety and to distinguish it from depressive syndromes. It also is often used in research as an indicator of caregiver distress Form Y, its most popular version, has 20 items for assessing trait anxiety and 20 for state anxiety. State anxiety items include: “I am tense; I am worried” and “I feel calm; I feel secure.” Trait anxiety items include: “I worry too much over something that really doesn’t matter” and “I am content; I am a steady person.” All items are rated on a 4-point scale (e.g., from “Almost Never” to “Almost Always”). Higher scores indicate greater anxiety. The STAI is appropriate for those who have at least a sixth-grade reading level.

Internal consistency coefficients for the scale have ranged from .86 to .95; test-retest reliability coefficients have ranged from .65 to .75 over a 2-month interval (Spielberger et al., 1983). Test-retest coefficients for this measure in the present study ranged from .69 to .89. Considerable evidence attests to the construct and concurrent validity of the scale (Spielberger, 1989). Eating Disorder Inventory (EDI-3) -

-

The EDI-3 consists of 91 items organised into 12 primary scales 1. Drive for thinness 2. Bulimia 3. Body dissatisfaction 4. Low self-esteem 5. Personal alienation 6. Interpersonal insecurity 7. Interpersonal alienation 8. Interoceptive deficits 9. Emotional dysregulation 10. Perfectionism 11. Asceticism 12. Maturity fears Yields 6 composites: one that is eating-disorder specific, and 5 that are general integrative psychological constructs i.e. ineffectiveness, interpersonal problems, overcontrol etc.

Useful as research tools Potential diagnostic and theoretical value Some valuable with good psychometric properties (not all, papers published to establish that) Some relatively underdeveloped Majority fail to include ‘validity’ scales as MMPI...
