Beck Depression Inventory-II (Beck, Steer, & Brown, 1996)

21-item self report for measuring the presence and severity of depression.

Internal reliability coefficients for the BDI-II range from .83 to .93 (Schulenberg & Yutrzenka, 2001; Whisman, Perez, & Ramel, 2000) . Test retest reliability coefficients range from .75 (Al-Musawi, 2001) to .96 (Sprinkle et al., 2002) ^a,c

Convergent validity; correlation coefficients of r = .83 for the SCID-1 (Sprinkle et al., 2002) and r = .84 for the Reynolds Adolescent Depression Scale (Krefetz, Steer, Gulab, & Beck, 2002) ^a,c

Beck Anxiety Inventory (BAI; Beck, Epstein, Brown & Steer, 1988 )

21-item self report for measuring the presence and severity of anxiety.

Internal reliability was high (Cronbach’s ALPHA = .94) and test retest reliability coefficient was .67 (Fydrich, Dowdall, & Chambless, 1992) ^a

Convergent validity; correlation between the BAI and Diary Anxiety being significantly higher than that between BAI and Diary Depression, and, compared to Trait Anxiety, the BAI was significantly less confounded with depression as measured by the BDI (Fydrich, Dowdall, & Chambless, 1992) ^a

Personality Assessment Inventory (PAI; Morey, 1991 )

Self-report multiple-scale inventory that consists of 344 items that constitute 4 sets of nonoverlapping scales: 4 validity scales, 11 clinical scales covering major categories of psychopathology based on the DSM nosology, 5 treatment scales measuring constructs relevant to treatment, and 2 interpersonal scales.

Internal reliabilities of the clinical scales are high, with median alphas for the full scales between .81 and .86. Test retest reliability coefficients of clinical scales ranged from .68 to .92 (Morey, 1991) ^a,c

Convergent and discriminate validity of the PAI was acceptable based on evaluations of mean profiles of relevant clinical groups (Morey, 1991) and correlations with other behavioral inventories (Costa & McCrae, 1992) ^a,c
