Abstract

This study tested the cognitive content specificity hypothesis of Beck’s cognitive theory using a web based report of mood and cognitions for that day completed once a week for 5 weeks. The use of a multi-wave design and structural equation modeling allowed for the separation of occasion-specific variability from over-time stability, thereby increasing sensitivity to the relatively brief changes in negative affect typical of student populations. To further increase specificity, an expanded set of cognitive themes was tested for depression, anxiety, and anger. Consistent with models indicating that these mood states share a general negative mood, all cognitions had a significant non-specific relationship to all three mood states. For tests of occasion-specific cognitive content specificity, thoughts of Transgression were incrementally specific to angry mood whereas Defectiveness, Hopelessness, and Abandonment were each specific to depressed mood. Failure was more strongly related to depression and anxiety than anger. Contrary to hypotheses, both Dependence and Vulnerability to Harm were non-specific only.

It is important to note that a high coefficient α, indicating acceptable internal consistency, does not insure that the scale is unidimensional (Nunnally and Bernstein 1994). The unidimensionality of a scale is best tested with confirmatory factor analysis to provide explicit tests of a two (or more) factor model versus a one factor model (Anderson and Gerbing 1988).

Inclusion criteria were a Center for Epidemiological Studies-Depression (CES-D; Radloff 1977) Scale score of 16 or above and/or a State-Trait Anger Expression Inventory-II (STAXI; Spielberger et al. 1995): Trait Anger Scale score of 23 or above. Scores of 16 on the CES-D and 23 on the STAXI have been identified as cut-off scores for significant levels of depressive and angry symptoms (Beekman et al. 1997; Spielberger 1999). Unfortunately, limitations in available space and time during the mass screening precluded administering a third screening measure (e.g., of anxiety).

In the tutorial, the participant was briefly instructed in how to combine information about the intensity, frequency, and duration of the distress during that day to make a severity rating for the distress items (depression, anxiety, anger). The participant then rated the frequency of certain thoughts identified in each of three vignettes and compared each rating to the ratings of a criterion group consisting of four clinical doctoral students and a clinical psychologist with training in behavioral assessment and cognitive theory and therapy for depression and anxiety. Feedback was given on these ratings so as to roughly calibrate each participant’s ratings with the criterion group.

Correlation coefficients between depression, anxiety, and anger within each model are depicted in Fig. 1 for the Defectiveness model. Given that these relationships were approximately equivalent across the final models for all cognitions, they are not reported in Table 2.
 
5
Although the factor and disturbance relationships are reported as correlations in Table 2, the actual SEM tests for differences in the magnitude of the relationship are conducted on the covariances.
