Key Descriptions

  • 4-point Likert scale responses for anxiety symptoms and severity within 1 week:
    0 = Not at all
    1 = mildly - but didn’t bother me much
    2 = Moderately - it wasn’t pleasant at times
    3 = Severely – I can barely stand it
  • Total score is calculated by calculating the sum of 21 items
  • Minimum score of 0 and a maximum score of 63
  • Score Interpretation:
    0 - 7 = minimal anxiety
    8 – 15 = mild anxiety
    16 – 25 = moderate anxiety
    26 – 63 = severe anxiety

Considerations

Based on normative data by Gillis et al., (1995 ) individuals 18 – 44 years old demonstrated a higher anxiety rating than those 45-65 years old.

  •  For overall sample, mean score = 6.6, (8.1)
  • Younger participants (aged 18 – 44) exhibited higher BIA scores (mean  = 7.3, (8.4)) than older participants (aged 45-65) (mean = 4.4, ( 6.3)

Internal Consistency

Healthy adults: (Wetherell and Gatz,2005; n = 32; mean age = 67.8 (7.1) years)

  • Excellent internal consistency (Chronbach’s alphas .81)

(Osman et al., 1997; n = 350; n = 145 males, mean age = 20.95 (3.52); n = 205 females, mean age = 21.64 (5.58) years)

  • Excellent internal consistency (Chronbach’s alphas .90)

Cut-Off Scores

Psychiatric outpatients: (Kabacoff et al., 1997 n = 154 non-psychotic adults over 55 years of age;  mean age = 65.86 (8.54) years)

  • No single cutoff score provided both high sensitivity and high specificity

     0 – 7 minimum anxiety

    1.00 - .94

    .08 - .32

    .35 - .60

Test/Retest Reliability

Adolescent psychiatric patients:  (Osman et al., 2002;  n = 240; mean age = 15.7 (.94) years)

  • Adequate test-retest reliability (ICC =.71)

Panic disorder with agoraphobia: (de Beurs et al.,1997; n = 82; mean age = 36.9 (9.1) years; mean duration of illness = 11.8 (8.1) years)

  • Excellent test-retest reliability (ICC =.83)

Psychiatric outpatients: (Beck et al., 1988; n = 1,086, 456 male mean age = 36.55 (12.41) years; 630 female, mean age = 35.69 (12.12) years)

  • Excellent test-retest reliability (ICC =.75)

Internal Consistency

General anxiety disorder: (Wetherell and Gatz, 2005; n = 75; mean age = 67.1 (8.2) years)

  •  Excellent internal consistency (Chronbach’s alphas .90)

Adolescent psychiatric patients: (Osman et al., 2002)

  • Excellent internal consistency (Chronbach’s alphas .92)

Panic Disorder with agoraphobia: (de Beurs et al., 1997)

  • Excellent internal consistency (Chronbach’s alphas .90)

Sleep disorders: (Sanford et al., 2008; n = 303; mean age = 47.8 (13.0) years)

  • Excellent internal consistency (Chronbach’s alphas .92)

Psychiatric outpatients: (Kabacoff, et al., 1997)

  • Excellent internal consistency (Chronbach’s alphas .90)

(Beck et al., 1988)

  • Excellent internal consistency (Chronbach’s alpha = .92)

Construct Validity

Convergent Validity

General Anxiety Disorders: (Wetherell & Gatz, 2005)

  • Adequate correlation of the Hamilton Anxiety Rating (.57)

Discriminant Validity

Psychiatric outpatients: (Kabacoff et al., 1997)

  • Excellent: Mean score differences between patients who met criteria for a current diagnosis of an anxiety disorder, and patients who did not meet criteria for a current anxiety disorder. A significant mean total score difference between patients with an anxiety disorder (M = 21.75, SD = 13.11) and patients without an anxiety disorder (M = 14.44, SD = 10.93) was obtained

(Beck et al., 1988)

Excellent: BAI-somatic subscale yielded a significant mean difference (t (124.4) = 3.42, p < .0001) between patients with an anxiety disorder (M = 11.54, SD = 9.05) and patients without an anxiety disorder (M = 7.46, SD = 6.99). Similarly, a significant mean difference (t (215) = 4.75, p < .00001) between patients with (M = 10.21, SD = 5.40) and without an anxiety disorder (M = 6.73, SD = 5.00) was obtained on the BAI-subjective subscale.
