TLDR
This model was tested by conducting separate factor analyses of the 90 items in the Mood and Anxiety Symptom Questionnaire, and the same 3 factors emerged in each data set, suggesting that the symptom structure in this domain is highly convergent across diverse samples.Abstract:
L. A. Clark and D. Watson (1991) proposed a tripartite model of depression and anxiety that divides symptoms into 3 groups: symptoms of general distress that are largely nonspecific, manifestations of anhedonia and low positive affect that are specific to depression, and symptoms of somatic arousal that are relatively unique to anxiety. This model was tested by conducting separate factor analyses of the 90 items in the Mood and Anxiety Symptom Questionnaire (D. Watson & L. A. Clark, 1991) in 5 samples (3 student, 1 adult, 1 patient). The same 3 factors (General Distress, Anhedonia vs. Positive Affect, Somatic Anxiety) emerged in each data set, suggesting that the symptom structure in this domain is highly convergent across diverse samples. Moreover, these factors broadly corresponded to the symptom groups proposed by the tripartite model. Inspection of the individual item loadings suggested some refinements to the model.read more

The validity of the Hospital Anxiety and Depression Scale: An updated literature review
TL;DR: HADS was found to perform well in assessing the symptom severity and caseness of anxiety disorders and depression in both somatic, psychiatric and primary care patients and in the general population.

Psychometric properties of the 42-item and 21-item versions of the Depression Anxiety Stress Scales in clinical groups and a community sample.
TL;DR: Lovibond et al. as discussed by the authors examined the factor structure, reliability, and validity of the Depression Anxiety Stress Scales (DASS; S. H. Lovibond & P. F. Lempitsky, 1995) and the 21-item short form of these measures, and found that the DASS distinguishes well between features of depression, physical arousal, and psychological tension and agitation.

The positive and negative affect schedule (PANAS): construct validity, measurement properties and normative data in a large non-clinical sample.
TL;DR: The PANAS is a reliable and valid measure of the constructs it was intended to assess, although the hypothesis of complete independence between PA and NA must be rejected and the utility of this measure is enhanced by the provision of large-scale normative data.

Does Positive Affect Influence Health
Sarah D. Pressman,Sheldon Cohen +1 more
TL;DR: This review highlights consistent patterns in the literature associating positive affect (PA) and physical health and raises serious conceptual and methodological reservations, but suggests an association of trait PA and lower morbidity and of state and traitPA and decreased symptoms and pain.

Temperament, personality, and the mood and anxiety disorders.
TL;DR: The review is organized primarily around L. A. Clark and D. Watson's (1991b) tripartite model for these disorders, but other influential approaches are also examined.

Toward a consensual structure of mood.
David Watson,Auke Tellegen +1 more
TL;DR: Reanalyses of a number of studies of self-reported mood indicate that Positive and Negative Affect consistently emerge as the first two Varimax rotated dimensions in orthogonal factor analyses or as thefirst two second-order factors derived from oblique solutions.

Tripartite model of anxiety and depression: psychometric evidence and taxonomic implications.
Lee Anna Clark,David Watson +1 more
TL;DR: In this article, a tripartite structure consisting of general distress, physiological hyperarousal (specific anxiety), and anhedonia (specific depression), and a diagnosis of mixed anxiety-depression was proposed.
