    Abstract Objectives: The coronavirus disease 2019 (COVID-19) pandemic was associated with substantial increases in anxiety and depressive symptoms. To understand individual risk, we examined a large set of potential risk factors for anxiety and depression in the pandemic context.
    Methods: Adults in the United States (N = 1200) completed eight online self-report assessments over 12 months of the COVID-19 pandemic. Area under the curve scores summarized cumulative experiences of anxiety and depression over the assessment period. A machine learning approach to elastic net regularized regression was used to select predictors of cumulative anxiety and depression severity from a set of 68 sociodemographic, psychological, and pandemic-related baseline variables.
    Results: Cumulative anxiety severity was most strongly explained by stress and depression-related variables (such as perceived stress) and select sociodemographic characteristics. Cumulative depression severity was predicted by psychological variables, including generalized anxiety and depressive symptom reactivity. Being immunocompromised or having a medical condition were also important.
    Conclusions: By considering many predictors, findings provide a more complete view than previous studies focused on specific predictors. Important predictors included psychological variables suggested by prior research and variables more specific to the pandemic context. We discuss how such findings can be used in understanding risk and planning interventions.

    Abstract Objective: Understanding how people respond to information about treatment options is important for informing efforts that promote treatment initiation and adherence. We examined the impact of informational treatment videos on treatment naive participants' views regarding the credibility of and their expectations for three treatment options.
    Materials and methods: Adults (N = 300) who had experienced elevated depressive symptoms but had not participated in a treatment for depression were randomly assigned to one of four conditions. Three of the conditions were shown videos, providing information about (1) cognitive behavioral therapy (CBT), (2) antidepressant medication (ADM), or (3) the combination of CBT and ADM. The fourth condition was not shown a video. Participants' self-reported views of the credibility of and expectations for treatment served as primary outcome variables.
    Results: Compared with the control condition, videos about active treatments enhanced credibility and expectations for those treatments. When comparing CBT and ADM alone, messaging about either treatment enhanced credibility of and expectations for that treatment. The CBT only video produced the most positive expectations and highest credibility for CBT. Likewise, the ADM only video led to the most positive expectations and credibility for ADM. The video focused on combined treatment did not lead to particularly positive views of the combined treatment option.
    Conclusion: These findings demonstrate the importance of providing focused messaging to enhance the credibility of and expectations for treatment. Future research is needed to examine the impact of messaging in different contexts, as well as the impact of such messaging on treatment seeking, adherence, and outcomes.

    Abstract Background: Although the importance of sleep difficulties in emotional disorders has long been acknowledged, the nature of the potential reciprocal relationship between sleep and depressive symptoms is not yet well understood. The coronavirus disease 19 pandemic provided a unique opportunity to study the interrelation of these symptoms over a period marked by increases in sleep and psychological difficulties.
    Methods: Using online data collection, we followed 1200 adults (59% male) through 1 year of the pandemic. Measures of sleep disturbance and depressive symptoms were assessed at eight time points. Factor analysis of the items from these two measures suggested separate insomnia and depressive symptom factors. A random intercept cross-lagged panel model was used to assess within-person relationships between factor analysis-informed subscales of insomnia and depressive symptoms.
    Results: Depressive symptoms predicted subsequent changes in insomnia symptoms; however, insomnia did not predict changes in depressive symptoms.
    Conclusions: Our findings suggest the impact of depressive symptoms on insomnia is evident, but the reverse is not. Implications of this finding along with the need for research addressing depressive symptoms and insomnia as treatment targets are discussed.

    Abstract Cognitive behavioral therapy (CBT) appears to achieve its effects at least in part by fostering the development of CBT skills. In an effort to leverage CBT skill development, our group developed and tested a skill-enhanced version of CBT (CBT-SE) in a recent trial. In this paper, we describe our work with a client who participated in a 12-week course of CBT-SE as part of that trial. Although homework is a critical aspect of CBT, the greater emphasis on skill development in CBT-SE means that homework is even more central. This client's course of treatment illustrates the potential benefits of a strong focus on skill development and the use of specific homework assignments to foster mastery and ongoing use of CBT skills. The client developed CBT skills at a rapid pace early in treatment and exhibited enduring symptom reductions. The experience of this client reinforces the value of a focus on CBT skills and highlights strategies for fostering skill development. Given the evidence in support of the therapeutic value of CBT skills and the well-established benefits of homework assignment, we encourage use of skill enhancing procedures, including in-session procedures and assignments that help clients develop and maintain ongoing skill use.

    Abstract DeRubeis and colleagues (2014a) proposed that psychotherapy research has been limited by underappreciated variability in how patients respond to psychotherapy. They proposed that the relationship between the quality of therapy and outcome varies according to patient response profiles. In a study of cognitive-behavioral therapy (CBT) for depression, we tested clinician ratings of this construct as a moderator of the relationship between therapist adherence to cognitive or behavioral methods in predicting symptom change. Patients (N = 125) participated in CBT for depression. Assessors rated response profiles following the intake and therapists rated them after the first session. We collected data on adherence at the first five sessions and symptoms at the first six sessions. Therapist ratings following the first session, but not assessor ratings at intake, moderated the relationship between each form of adherence and symptom change. Patients given lower ratings (identifying them as spontaneous remitting or easy patients) had a stronger relationship between adherence and greater symptom change, with this relationship reversed such that adherence was related to less robust symptom change for those with the highest ratings (intractable or challenging patients). Our findings suggest promise for clinical evaluation of response profiles. We encourage future research evaluating refinements to such measures.

    Abstract Objective: Researchers have been interested in the role of negative affect (NA) and positive affect (PA) in cognitive behavioral therapy (CBT) for depression. We examined cognitive change (CC) and these two affect variables across the course of CBT.
    Method: Patients (N = 125; M age = 31.7, SD = 13.35; 60% female; 83% Caucasian) participated in 16 weeks of CBT for depression. They completed the Beck Depression Inventory-II (BDI-II) and the Immediate Cognitive Change Scale at each session and a measure of affect before and after each session.
    Results: NA decreased (rate of change p < .001, d = -1.08) and PA increased (p < .001, d = 0.53) during treatment. CC predicted next-session PA, 0.06, 95% CI [0.01, 0.11], and NA, -0.09, 95% CI [-0.14, -0.04], and was concurrently associated with change in PA, 0.36, 95% CI [0.30, 0.42], and NA, -0.32, 95% CI [-0.42, -0.26], over the course of a session. Presession PA, 0.22, 95% CI [0.17, 0.26], and NA, -0.13, 95% CI [-0.17, -0.08], predicted postsession CC, while pre to postsession change in PA, -0.05, 95% CI [-0.09, -0.002], and NA, 0.06, 95% CI [0.01, 0.11], predicted change in depressive symptoms.
    Conclusions: Although NA and PA both change in CBT, the changes in PA are more modest. Both NA and PA predict symptom change, consistent with the possibility that increasing PA may be beneficial. CC and affect change are reciprocally related, suggesting that CC may contribute to affect change, while affect may also facilitate CC. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

    Abstract Background: Prior to DSM-5, depression had long been conceptualized as symptoms without cause or disproportionate to one's circumstances. A central challenge to considering whether a depressive reaction is disproportionate is the lack of measures assessing disproportionality. Drawing on a study of patients participating in cognitive behavioural therapy for depression, we evaluate two new measures of the disproportionality of one's depressive symptoms to their recent life circumstances.
    Methods: To assess the disproportionality of depressive symptoms, we developed an interview-based assessment and a brief self-report measure. We employed both assessments in a sample of 126 patients who participated in cognitive behavioural therapy for depression.
    Results: Initial evidence for the reliability and validity of both self-report and interview-based approaches appeared promising. Interview judges demonstrated strong inter-rater reliability on life stress ratings, and both forms of disproportionality showed a pattern of correlations with variables reflecting greater clinical complexity, including self-reported personality dysfunction and symptom severity. Comorbid generalized anxiety disorder (GAD) was the only previously proposed marker of complicated depression to significantly predict both disproportionality scores.
    Limitations: The sample had limited ethnic diversity and tended to be highly educated. Participants all met criteria for major depressive disorder and sought treatment.
    Conclusions: Two assessments of the disproportionality of depressive reactions demonstrated evidence of reliability and validity. Despite limited efforts at assessment to date, these results suggest these measures may be able to reliably distinguish the disproportionality of depressive reactions and allow clinicians to better assess contextual life stress depressive disorders.

    Abstract Whether and how therapists' delivery of cognitive behavioral therapy (CBT) for depression differs by patients' ethnicity or race remains unclear. In this study, 218 therapists were randomized to clinical vignettes that involved the same text but varied in whether the accompanying image depicted a Black or White patient. Therapists exhibited three key differences in their views of clinical strategies for working with Black as compared to White patients. They viewed cognitive change strategies as less therapeutic and validation strategies as more therapeutic for Black patients. They reported similar differences for the time they would spend on each kind of strategy. When asked to compare the relative importance of cognitive change vs. validation strategies specifically, therapists rated validation as more important for Black than White patients. Among therapists presented with Black patients, positive racial attitudes were associated with viewing cognitive change and validation strategies as more therapeutic. These results suggest therapists tend to believe it is desirable to incorporate cognitive methods more limitedly when working with Black patients. Whether such adaptations enhance or detract from the care of Black patients is an important issue that merits future investigation.
