Anxiety and depression are two disorders frequently diagnosed in adults. Given serious adverse affects such as physical health problems, interpersonal relationship difficulties, and suicide, differentiation in treatment of these often comorbid disorders is a necessity in providing appropriate care. The tripartite model of anxiety and depression (Clark & Watson, 1991) proposes that these disorders are linked by a common trait (Negative Affect) and differentiated by a trait common to depression (lack of Positive Affect) and a trait common to anxiety (Physiological Hyperarousal). The Clinical Assessment of Depression (CAD; Bracken & Howell, 2004), a recently published selfreport narrow-band measure of depression, includes a measure of anxiety related symptoms in its subscale structure. This study explores the validity of the CAD with two established measures: the Beck Depression Inventory – II (Beck, Steer, & Brown, 1996) and the Beck Anxiety Inventory (Beck, & Steer, 1993). College students of 18 to 52 years of age (n = 295) enrolled in undergraduate courses in psychology at a south central Kentucky university provided the study data. These individuals were divided into nonclinical and clinical samples based on self disclosure of a clinical diagnosis to examine differences between groups. Strong positive correlations (above r = .60) between similar CAD scales and total scores on the BAI and BDI-II supported convergent validity for the nonclinical sample. All comparisons supported convergent validity for the clinical sample except the correlation between the BDI-II Total Score and the CAD - Depressed Mood subscale (r = .56). Weak to moderate correlations (r = 0.0 to .59) between dissimilar scales supported divergent validity for all dissimilar comparisons in both samples except the correlation between the BDI-II and the CAD-Anxiety/Worry subscale in the nonclinical sample (r = .66). Hotelling-Williams t-tests were performed to compare correlations of similar and dissimilar constructs. Significant results emerged most comparisons in the nonclinical group support the use of the CAD diagnostic assessment. However, nonsignificant findings for the CAD Anxiety/Worry subscale indicate that this measure lacks the ability to aid diagnose significant levels of anxiety. Only one significant difference between correlations was found for the clinical sample with the CAD – Diminished Interest subscale evidencing significantly stronger correlations with the BDI-II than the BAI. The lack of significant differences for the other CAD scales is discussed relative to the small clinical sample size and the heterogeneity of disorders represented. Results support the use of the CAD as an adequate diagnostic tool for depression with college students. Results did not support the use of the CAD in differential diagnosis of anxiety with college students within the framework of the tripartite model. Implications of the findings are discussed to aid in practice and to suggest further research.

Methods: A before and after clinical assay was conducted with patients 17 years old or older who were included in the study after signing formal consent. Individuals answered, on their first interview, the Beck Depression Inventory (BDI) and the Beck Anxiety Inventory (BAI) and a pattern questionnaire about demographic and social-economic factors. Information regarding their illness and current medication was withdrawn from medical charts. At the end of their follow-up, patients answered again the BDI and the BAI. Patients initially classified as presenting minimum, mild, moderate or severe levels of depression and anxiety had their initial and final mean scores evaluated. Results: We included 64 HIV/AIDS patients in this study. The mean age (±SD) was 36 years (9,3). The mean time (±SD) between the first and second interview was 14 days (8,9). All depression levels and mild and moderate categories of anxiety presented reductions in scores with statistical significance (p< 0,05). Mean improvement of initial and final BDI scores was 7.03 points (95% CI 5,51-8,55) and for BAI scores, 6,23 points (95%CI 4,10-8,37). Conclusions: This study identified a favourable impact of the day-hospital clinic on HIV/AIDS patients emotional state without psychotherapeutic intervention. / Objetivo: Determinar impacto das intervenções um Hospital-Dia no estado emocional de pacientes HIV/AIDS atendidos no Hospital-Escola da Universidade Federal de Pelotas. Métodos: Um ensaio clínico antes e depois foi realizado com pacientes HIV/AIDS com idade mínima de 17 anos, os quais foram incluídos no estudo após assinatura de consentimento informado. Os entrevistados realizaram a primeira investigação através do Inventário de Depressão Beck (BDI) e Ansiedade Beck (BAI) e um questionário padrão sobre dados demográficos e sócio-econômicos. Dados referentes à doença e medicações foram obtidos de prontuário médico. Ao final do atendimento no HD, pacientes responderam novamente ao BDI e BAI. Avaliou-se o escore médio inicial e final dos pacientes que inicialmente encontravam-se nos níveis mínimo, leve, moderado e grave tanto para depressão quanto para ansiedade. Resultados: Foram incluídos no estudo 64 pacientes HIV/AIDS. A idade média foi de 36 anos (dp 9,3); O tempo médio entre a primeira e a segunda entrevista foi de 14 dias (dp 8,9). Todos os níveis de depressão e as categorias leve e moderada, referentes à ansiedade, apresentaram redução dos escores com significância estatística (p<0,05). A melhora média dos escores iniciais e finais do BDI foi de 7,03 pontos (95% IC 5,51-8,55) e do BAI de 6,23 pontos (95% IC 4,10-8,37). Conclusões: Este estudo identificou um impacto favorável do Hospital-Dia no estado emocional dos pacientes HIV/AIDS acompanhados no serviço sem a realização de intervenção psicoterápica.
