RESUMEN

Anxiety typically arises early in childhood and decreases during school age. However, little is known about the earlier developmental course of anxiety in preschool, especially in at risk children, posing a clinically important problem. Given that anxiety in youth has a chronic course for some and also predicts later development of other mental health problems, it is important to identify factors early in development that may predict chronic anxiety symptoms. At-risk children (oversampled for depression) and caregivers completed 6 assessment waves beginning at preschool age (between 3-5.11 years of age) up through 6.5 years later. Growth mixture models revealed 4 distinct trajectories: 2 stable groups (high and moderate) and 2 decreasing groups (high and low). Important to note, the high stable anxiety group had greater baseline depression and social adversity/risk, higher average maternal depression over time, and poorer average social functioning over time compared to the high decreasing group. The high decreasing group also had greater externalizing/attention deficit hyperactivity disorder scores than the low decreasing group. Children with anxiety in early childhood who also experience high depression, social adversity/risk, maternal depression, and poor social functioning may be at risk for chronic symptoms over time.

RESUMEN

Several models have been proposed to conceptualize worry. Broadly, the models can be classified as cognitive (including the Avoidance Model, the Intolerance of Uncertainty Model, and the Metacognitive Model) and emotion-focused (including Emotion Dysregulation and Acceptance-Based models). Although these models have received strong empirical investigation in primarily non-Hispanic White samples, no known study has examined the applicability to racial and ethnic minority groups. The current study compared the proportion of variance explained by cognitive and emotion-focused models of worry in White and Black samples. Results indicated that cognitive and emotion-focused models significantly predicted worry in both Black and White samples. However, the overall amount of variance in worry explained by the models was less for Black samples. Specifically, controlling for gender, the cognitive models explained 53% of the variance in worry in the White sample compared with 19% in the Black sample. Similarly, the emotion-focused models explained 34% of the variance in worry in the White sample but only 13% in the Black sample. These findings suggest that well-established conceptual frameworks for worry failed to explain the bulk of the variance in worry in Black samples, leaving much unknown. Additional research is needed to identify key variables that may further explain worry in ethnic minority samples.

RESUMEN

The current study examined the effectiveness of brief cognitive behavior therapy (CBT) for severe mood disorders in an acute naturalistic setting. The sample included 951 individuals with either major depressive disorder (n = 857) or bipolar disorder with depressed mood (n = 94). Participants completed a battery of self-report measures assessing depression, overall well-being, and a range of secondary outcomes both before and after treatment. We found significant reductions in depressive symptoms, worry, self-harm, emotional lability, and substance abuse, as well as significant improvements in well-being and interpersonal relationships, post-treatment. Comparable to outpatient studies, 30% of the sample evidenced recovery from depression. Comparison of findings to benchmark studies indicated that, although the current sample started treatment with severe depressive symptoms and were in treatment for average of only 10 days, the overall magnitude of symptom improvement was similar to that of randomized controlled trials. Limitations of the study include a lack of control group, a limitation of most naturalistic studies. These findings indicate that interventions developed in controlled research settings on the efficacy of CBT can be transported to naturalistic, "real world" settings, and that brief CBT delivered in a partial hospital program is effective for many patients with severe depressive symptoms.

RESUMEN

Although theoretical work has suggested that reciprocal behavior patterns between parent and child may be important in the development of childhood anxiety, most empirical work has failed to consider the bidirectional nature of interactions. The current study sought to address this limitation by utilizing a sequential approach to exploring parent-child interactions. Participants included 161 children (ages 3-12 years) and their parents. Parent and child dyads were classified into four categories: anxious parent-anxious child (n = 45), anxious parent-nonanxious child (n = 45), nonanxious parent-anxious child (n = 21), and nonanxious parent-nonanxious child (n = 50). Parent and child behaviors were coded from two 10-min interactions. Results indicated that anxious parents of children with anxiety disorders were more likely to respond with negative behaviors, which their child then mirrored. Nonanxious parents of nonanxious children responded with more warmth, which was then mirrored by their child. These results provide evidence for differential patterns of behaviors between anxious and nonanxious parents and children following critical moments in their interactions.

RESUMEN

Generalized anxiety disorder (GAD) has been associated with significant impairment and estimates of human and economic burden associated with the disorder are substantial. Little has been done, however, to examine impairment associated with subthreshold presentations of the disorder in medically underserved populations. This study compared primary care patients with GAD (n = 30), subthreshold GAD (n = 21), worry (n = 79), and no worry (n = 199) on measures of human and economic burden. On measures of human burden, all three symptomatic groups reported poorer perceived physical health, greater stress, and sleep difficulty. Worried and subthreshold groups also reported lower social support. For economic burden, GAD and worry groups reported a greater number of prescription medications. However, when co-morbid depression was accounted for the effect was no longer significant. Groups did not differ on employment status, number of visits to the clinic in the last 90 days, or physical health. Results are discussed in terms of identification, prevention, and intervention for GAD in primary care settings.

RESUMEN

Perceived control has been identified as an important factor in the development and maintenance of mood disorders, and worry has been shown to have a unique relationship with psychological distress associated with mood disorders. The relationships between these variables have received little attention in the literature, and even less in terms of the role racial status may serve. The current study investigated the structural relationship between psychological distress and perceived control in predicting self-reported worry as well as potential differences in paths to worry in African American and European American young adults using a structural equation model. One hundred twenty-one European American and 100 African American undergraduate students completed the Beck Depression Inventory (BDI), the State Trait Anxiety Inventory (STAI), the Anxiety Control Questionnaire (ACQ), and the Penn State Worry Questionnaire (PSWQ). Results suggest that psychological distress and perceived control predict worry in both the African American and European American samples, however there were significant differences in terms of which construct contributed most. For African Americans, psychological distress contributed significantly more to worry than perceived control, whereas low perceived control contributed more to worry for European Americans. Implications and suggestions for future research are discussed.

RESUMEN

Although depressive disorders are among the most common disorders in youth, highly efficacious treatments for childhood affective disorders are lacking. There is significant need to better understand the factors that contribute to the development and maintenance of depression in youth so that treatments can be targeted at optimal mechanisms. The aim of the current paper was to synthesize research on cognitive and neurobiological factors associated with youth depression, guided by De Raedt and Koster's model (2010) for vulnerability to depression in adults. Consistent with model predictions, there is evidence that attentional impairments are greatest in the context of negative information, relative to positive or neutral information, and some evidence that attentional deficits are associated with rumination in depressed youth. However, we found little evidence for the model's assumption that attentional bias is an etiological and maintenance factor for depression. There are several other model predictions that require additional study as current data are lacking. Overall, De Raedt and Koster's (2010) integrative cognitive and biological framework has tremendous potential to move the field forward in understanding the development of depression in youth. Additional longitudinal studies incorporating measures across biological and cognitive levels of analysis are needed.

RESUMEN

The current study investigated factors related to specific phobia domains and differences in patterns among African American and Caucasian American adults. Subjects were 100 African Americans and 121 Caucasian Americans who completed the Fear Survey Schedule--Second Edition (FSS-II). Fears related to specific phobia domains were first examined, with frequencies differing between African American and Caucasian American samples on three of the six specific phobia domains. A confirmatory factor analysis was conducted to determine the patterns of specific phobias among the African American sample. The trimmed model for the African American sample included natural environment, animal and social anxiety specific phobia factors as latent, exogenous variables. Data from the Caucasian American sample provided a poor fit to this model. Instead, the trimmed model for the Caucasian American sample included the situational, animal and social anxiety factors. The natural environment-type specific phobia factor did not have adequate fit for the Caucasian American sample as in the African American sample. Results indicated that different factor loading patterns of fear-related stimuli may exist among African American and Caucasian American young adults. Potential explanations and future directions are discussed.

RESUMEN

Distress intolerance (DI) is defined as a perceived or actual inability to withstand distressing emotional or somatic states, which motivates the use of avoidance strategies. Despite widespread interest in DI, key questions about its underlying structure remain unanswered. The current study evaluated the latent structure of DI in two large samples using four-indicators and three taxometric procedures (MAMBAC, MAXEIG, and L-Mode). Data interpretation relied primarily on the Comparison Curve Fit Indices (CCFI). Overall, results from the three non-redundant procedures suggested that DI was more accurately characterized by a dimensional rather than a categorical conceptualization. Implications for assessment and conceptual models of DI are discussed.

RESUMEN

BACKGROUND AND OBJECTIVES: Attention control deficits and repetitive negative thinking (RNT; i.e., rumination) may be key factors in the development and persistence of depression and anxiety, although their role in symptom development remains poorly understood. This represents a gap in the literature, as interventions targeting attention control and associated RNT may enhance interventions and prevent costly relapse. The current study was designed to examine the serial indirect effects of transdiagnostic RNT and negative affect recovery following a lab-induced stressor on the association between attention control deficits and trait anxiety and depression. METHODS: Participants were N = 583 university students who completed validated measures of RNT, anxiety, depression, and mood ratings pre- and post-stressor. Stress was induced using a modified version of the Trier Social Stress Test. RESULTS: Results of cross-sectional indirect effects models indicated that RNT and mood recovery explained the association between attention control deficits and trait anxiety and depression. Results from reversed models indicated that only the indirect effect of RNT was significant. CONCLUSIONS: Findings suggest that RNT and mood recovery processes play an important role in explaining anxiety and depression symptoms. Additional work is needed to examine their role in symptom development and maintenance over time.

RESUMEN

This study explored an intensive 3-week training program and use of psychiatric service dogs for military-related posttraumatic stress disorder (PTSD) and associated symptoms. The sample included 2 separate cohorts of military veterans (n = 7 and n = 5) with prior diagnoses of PTSD. Participants completed self-report measures assessing PTSD, depression, perception of social support, anger, and overall quality of life 1 month prior to the training (baseline), at arrival to the training site, and 6-month follow-up. Results indicated that, for this sample, there was a statistically significant decrease in PTSD and depression symptoms from pre- to posttreatment, as well as 6-month follow-up. For most participants decreases were both clinically significant and reliable changes. Further, participants reported significant reductions in anger and improvement in perceived social support and quality of life. Limitations of the study include a lack of control group, a limitation of most naturalistic studies, as well as small sample size. Despite this, the findings indicate that utilizing psychiatric service dogs, coupled with an intensive trauma resilience training program for veterans with ongoing symptoms, is feasible as a complementary treatment for PTSD that could yield beneficial results in terms of symptom amelioration and improvement to overall quality of life.

RESUMEN

Although depression and anxiety are common in youth (Costello et al. 2003), factors that put children at risk for such symptoms are not well understood. The current study examined associations between early childhood cognitive control deficits and depression and anxiety over the course of development through school age. Participants were 188 children (at baseline M = 5.42 years, SD = 0.79 years) and their primary caregiver. Caregivers completed ratings of children's executive functioning at preschool age and measures of depression and anxiety severity over seven assessment waves (a period of approximately 7.5 years). Longitudinal multilevel linear models were used to examine the effect of attention shifting and inhibition deficits on depression and anxiety. Inhibition deficits at preschool were associated with significantly greater depression severity scores at each subsequent assessment wave (up until 7.5 years later). Inhibition deficits were associated with greater anxiety severity from 3.5 to 7.5 years later. Greater shifting deficits at preschool age were associated with greater depression severity up to 5.5 years later. Shifting deficits were also associated with significantly greater anxiety severity up to 3.5 years later. Importantly, these effects were significant even after accounting for the influence of other key predictors including assessment wave/time, gender, parental education, IQ, and symptom severity at preschool age, suggesting that effects are robust. Overall, findings indicate that cognitive control deficits are an early vulnerability factor for developing affective symptoms. Timely assessment and intervention may be beneficial as an early prevention strategy.

RESUMEN

OBJECTIVE: Studies have reported associations between cognitive behavioral therapy (CBT) skill use and symptom improvement in depressed outpatient samples. However, little is known regarding the temporal relationship between different subsets of therapeutic skills and symptom change among relatively severely depressed patients receiving treatment in psychiatric hospital settings. METHOD: Adult patients with major depression (N = 173) receiving combined psychotherapeutic and pharmacological treatment at a psychiatric hospital completed repeated assessments of traditional CBT skills, DBT skills and psychological flexibility, as well as depressive and anxiety symptoms. RESULTS: Results indicated that only use of behavioral activation (BA) strategies significantly predicted depressive symptom improvement in this sample; whereas DBT skills and psychological flexibility predicted anxiety symptom change. In addition, a baseline symptom severity X BA strategies interaction emerged indicating that those patients with higher pretreatment depression severity exhibited the strongest association between use of BA strategies and depressive symptom improvement. CONCLUSIONS: Findings suggest the importance of emphasizing the acquisition and regular use of BA strategies with severely depressed patients in short-term psychiatric settings. In contrast, an emphasis on the development of DBT skills and the cultivation of psychological flexibility may prove beneficial for the amelioration of anxiety symptoms.

RESUMEN

BACKGROUND AND OBJECTIVES: Distress intolerance (DI) has been identified as a potential risk factor for a variety of maladaptive avoidance behaviors, including worry. However, mechanisms linking DI to specific behaviors remain poorly understood. One hypothesis is that DI is a general vulnerability that confers risk of particular avoidance behaviors via more specific, lower-order vulnerabilities. The current study examined associations between DI and worry-related cognitions. DESIGN: A multiple mediator model tested the hypothesis that worry-related variables (intolerance of uncertainty [IU], cognitive avoidance, beliefs about worry, and negative problem orientation) mediated the association between DI and worry. METHODS: An undergraduate student (n = 281) and a clinical (n = 123) sample completed self-report measures. RESULTS: Across samples, worry was associated with higher levels of DI, IU, cognitive avoidance, beliefs about worry, and negative problem orientation. Mediation results differed somewhat between the two samples. In the undergraduate sample, IU, negative beliefs about worry, and positive beliefs about worry mediated the association between DI and worry. In the clinical sample, negative problem orientation and negative beliefs about worry mediated the association between DI and worry. CONCLUSIONS: Results provide initial evidence that DI may be associated with worry via unique risk factors.

RESUMEN

Repetitive negative thinking (RNT) is a common symptom across depression and anxiety disorders and preliminary evidence suggests that decreases in rumination and worry are related to improvement in depression and anxiety symptoms. However, despite its prevalence, relatively little is known about transdiagnostic RNT and its temporal associations with symptom improvement during treatment. The current study was designed to examine the influence of RNT on subsequent depression and anxiety symptoms during treatment. Participants (n = 131; 52% female; 93% White; M = 34.76 years) were patients presenting for treatment in a brief, cognitive behavior therapy based, partial hospitalization program. Participants completed multiple assessments of depression (Center for the Epidemiological Studies of Depression-10 scale), anxiety (the 7-item Generalized Anxiety Disorder Scale), and repetitive negative thinking (Perseverative Thinking Questionnaire) over the course of treatment. Results indicated statistically significant between and within person effects of RNT on depression and anxiety, even after controlling for the effect of time, previous symptom levels, referral source, and treatment length. RNT explained 22% of the unexplained variability in depression scores and 15% of the unexplained variability in anxiety scores beyond that explained by the control variables. RNT may be an important transdiagnostic treatment target for anxiety and depression.

RESUMEN

Although the association between trauma exposure and posttraumatic stress disorder (PTSD) symptoms is well established, how such trauma is incorporated into identity, or the centrality of the negative event, is also of considerable importance in understanding the development of psychological symptoms. Alternatively, positive event centrality may have positive effects on well-being in the face of trauma. Thus, the current study examined associations between positive and negative event centrality, and both adaptive and maladaptive outcomes, above and beyond the impact of traumatic experience. A sample of 214 college students completed a series of self-report questionnaires. As anticipated, negative event centrality predicted PTSD and other maladaptive measures of functioning, even after controlling for traumatic experience. High levels of positive event centrality predicted adaptive, as opposed to maladaptive, psychological functioning. Results also suggested that both positive and negative event centrality predicted posttraumatic growth, controlling for traumatic experience. These findings suggest that assessing centrality of trauma may also be valuable in the prediction of psychological symptoms. The implications of these findings and proposals for future work are discussed further.

RESUMEN

The Penn State Worry Questionnaire (PSWQ) is a 16-item self-report measure considered the gold-standard assessment instrument for worry. Two abbreviated versions of the PSWQ have also been developed. An 8-item measure (PSWQ-A) was designed to address poor model fit of the full version with older adult samples, and a 3-item version (PSWQ-3) was developed in a clinical setting to avoid problems related to the reverse-scored items and to increase clinical utility. Preliminary examinations of the abbreviated forms have been promising, but additional psychometric evaluation is needed to confirm their reliability and validity. The current study compared psychometric properties of the 3 versions of the PSWQ in a heterogeneous clinical sample of 272 patients presenting for treatment in a partial hospital setting. Results suggested that scores for all 3 versions had good internal consistency; convergent validity with anxiety, stress, intolerance of uncertainty, negative problem orientation, and negative beliefs about worry; as well as adequate discriminant validity with depression, emotional lability, and substance abuse. On all 3 versions, individuals with generalized anxiety disorder (GAD) scored higher than those without the disorder, and across all participants, scores decreased from pre- to posttreatment. Finally, scores on the 3 versions showed similar levels of sensitivity and specificity as screening tools for GAD. Overall, the PSWQ-A and PSWQ-3 scores appear to be internally consistent and valid measures of worry that performed similarly to the full 16-item PSWQ. Given the strong psychometric properties of the shorter form scores, clinicians may prefer such forms, as they are quick to administer and easy to score in session.

RESUMEN

Generalized anxiety disorder (GAD) is characterized by "pathological" worry, suggesting that GAD worriers differ qualitatively from non-GAD worriers. However, results from taxometric studies of worry in undergraduate and community samples have been mixed and to date, no studies have utilized clinical samples. The current study examined the latent structure of worry and GAD symptoms in a diagnostically heterogeneous clinical sample. Indicators were selected from the Penn State Worry Questionnaire-Abbreviated (n=1175) and the GAD-7 (n=638) and submitted to three taxometric procedures: MAXCOV, MAMBAC, and L-Mode. Results from all three procedures suggested that both worry and generalized anxiety are best conceptualized as dimensional constructs. Findings also indicated that ongoing conceptualization, assessment, and treatment of worry and GAD may be hampered by the application of a categorical framework.

RESUMEN

Despite the well-established role of distress intolerance (DI) in a wide range of psychological disorders, few studies have examined whether DI improves during treatment and whether these changes are associated with symptom outcomes. Patients (N=626) enrolled in a brief cognitive-behavioral partial hospital program completed pre- and posttreatment measures of DI. Results indicated that DI decreased significantly during treatment, with more than 30% of the sample exhibiting a reduction of more than 2 standard deviations from the sample mean. Women reported higher DI than men at baseline; however, there were no gender differences in changes in DI over time. Participants also completed a pre- and posttreatment measure of depression and a subset completed a measure of anxiety (n=167). DI was associated with more severe depression and anxiety at pre- and posttreatment, with participants who reported a decrease in DI also reporting lower depression and anxiety symptoms at post-treatment. These results further highlight the transdiagnostic relevance of DI and suggest that DI may be a relevant factor in treatment outcome for depression and anxiety.

RESUMEN

BACKGROUND: Prior research has found that pretreatment expectations of symptom improvement are positively correlated with depressive symptom change. The current investigation extends previous research by examining whether pretreatment outcome expectancies predict symptom change across several diagnostic categories within the context of an acute, naturalistic psychiatric setting. METHODS: Analyses were conducted to examine whether pretreatment outcome expectancies (credibility/expectancy questionnaire [CEQ]) predicted symptom improvement within major depression (N=420), bipolar disorder (N=120) and psychosis (N=36). Bootstrap mediation analyses were conducted to examine whether acquisition of cognitive behavioral therapy (CBT) skills (cognitive behavior therapy skills questionnaire [CBTSQ]) may mediate expectancy-outcome relations. RESULTS: Results indicated a differential pattern of associations across diagnoses. Patient CBT skills emerged as a significant mediator of expectancy-outcome relations, but only in the major depression group. Both behavioral and cognitive skills were significantly, and independently, associated with symptom improvement. LIMITATIONS: Sample sizes were small in the bipolar manic subgroup and psychosis group. CBT skills and symptom measures were assessed at concurrent time points. CONCLUSIONS: The present findings suggest that patient expectancies and CBT skills may have a differential impact on symptom change as a function of diagnostic category. The implication of these results and directions for future research are discussed.
