Work-Related Cognitive Behavioral Therapy for racially and economically diverse unemployed persons with social anxiety: A randomized clinical trial.

Individuals with Social Anxiety Disorder (SAD) are at risk for employment problems. This multi-site trial examined the efficacy of Work-Related Cognitive Behavioral Therapy provided alongside vocational services as usual (WCBT+VSAU), a group-based treatment designed to improve mental health and employment outcomes for individuals with SAD. Vocational service-seeking participants with SAD (N = 250) were randomized to either WCBT+VSAU or VSAU-alone. Hypotheses were that participants randomized to WCBT+VSAU would report less social anxiety, less depression, and more hours worked than participants randomized to VSAU-alone. WCBT+VSAU participants had significantly greater improvements on the Liebowitz Social Anxiety Scale (LSAS; d=-.25, CI=-0.49 to -0.02, p = .03) at post-assessment compared to VSAU-alone. The conditions did not differ on any variable at later time points or on secondary outcomes. Unexpectedly, participants randomized to VSAU-alone experienced LSAS improvements, similar to WCBT+VASU at later timepoints. Baseline psychological flexibility (beta=-.098 [-0.19-0.008]) and depression (beta=-0.18 [-0.34-0.009]) moderated change in social anxiety. Participants with lower psychological flexibility and higher depression responded more strongly to WCBT+VSAU than VSAU-alone over the duration of the study, suggesting that WCBT+VSAU may particularly benefit those with greater psychopathology. Results indicate that vocational centers are promising settings for treating SAD and employment-focused refinements are likely needed to improve work outcomes.

A multi-modal assessment of fear conditioning in adolescent anorexia nervosa.

OBJECTIVE: Anorexia nervosa (AN) is a pernicious psychiatric disorder which is principally characterized by a fear of weight gain. Notwithstanding the centrality of fear in the psychopathology of AN, controlled assessments of negative valence systems are lacking. Herein we assess fear conditioning in adolescent females with AN. METHOD: Adolescent girls (Mage = 14.6 years, ±1.57) with DSM-5 diagnoses of AN (N = 25) and age-matched control girls (Mage = 14.8 years, ±1.46) with no DSM-5 diagnoses (N = 25) completed structured clinical interviews and participated in a classical three-phase Pavlovian fear conditioning paradigm. Participants with comorbid anxiety disorders were excluded. Skin conductance response (SCR) was measured, alongside self-reported fear, valence, and fear expectancy ratings. RESULTS: Both groups demonstrated significant differential acquisition across all four measures. Regarding group comparisons, no differences emerged for self-reported fear, valence, and fear expectancy ratings during acquisition, although for SCR, those with AN demonstrated reduced physiological arousal relative to controls. Both groups demonstrated significant differential extinction for unconditioned stimuli (US) expectancy, self-report fear, and self-report valence. No statistically significant group differences were evident during extinction to the conditioned stimuli (CS)+, on any outcome measure. However, controls reported more positive valence to the CS- than those with AN. CONCLUSIONS: Contrary to our hypotheses, our preliminary assessment did not find support for elevated fear responding among adolescent girls with AN with regards to fear acquisition or extinction. These data suggest that AN in adolescent girls may not be associated with a heightened propensity to acquire fear, but conversely, may suggest that exposure treatments for AN may be helpful, since extinction learning is intact in AN. PUBLIC SIGNIFICANCE: AN is characterized by fear-related symptoms, including food and weight-related fear, and behavioral avoidance, yet controlled studies assessing fear learning are limited. Our preliminary assessment of adolescent AN indicates no abnormalities in fear learning among adolescents with AN. These findings may inform existing mechanistic models of AN psychopathology, and the development of exposure-based treatments for AN.

Enhancing Racial/Ethnic Equity in College Student Mental Health Through Innovative Screening and Treatment.

Although college campuses are diversifying rapidly, students of color remain an underserved and understudied group. Online screening and subsequent allocation to treatment represents a pathway to enhancing equity in college student mental health. The purpose of the current study was to evaluate racial/ethnic differences in mental health problems and treatment enrollment within the context of a largescale screening and treatment research initiative on a diverse college campus. The sample was comprised of n = 2090 college students who completed an online mental health screening survey and were offered either free online or face-to-face treatment based on symptom severity as a part of a research study. A series of ordinal, binomial and multinomial logistic regression models were specified to examine racial/ethnic differences in mental health problems, prior treatment receipt, and enrollment in online and face-to-face treatment through the campus-wide research initiative. Racial/ethnic differences in depression, anxiety and suicidality endorsed in the screening survey were identified. Students of color were less likely to have received prior mental health treatment compared to non-Hispanic white students, but were equally likely to enroll in and initiate online and face-to-face treatment offered through the current research initiative. Rates of enrollment in online therapy were comparable to prior studies. Online screening and treatment may be an effective avenue to reaching underserved students of color with mental health needs on college campuses. Digital mental health tools hold significant promise for bridging gaps in care, but efforts to improve uptake and engagement are needed.

Acquisition of behavioral avoidance: task-irrelevant conditioned stimuli trigger costly decisions.

Individuals avoid stimuli which are associated with aversive experience to preserve safety. However, behavioral avoidance also causes impairments and prevents the individual from attaining positive rewards. Little is known about the link between fear acquisition and the development of behavioral avoidance in the presence of potential rewards. Therefore, two experiments investigated the impact of fear conditioning on a subsequent gambling task. In an experimental group (n = 30) advantageous choices (higher reward probability) were linked to a fear-relevant stimulus that was associated with an aversive unconditioned stimulus (US) during fear conditioning (conditioned stimulus, CS+). A disadvantageous choice (lower reward probability) was, however, linked to a safe stimulus that was never associated with the US (CS-). In a control group (n = 25), fear conditioning was followed by a similar gambling task with novel stimuli. A second experiment focused on individual predictors of avoidant decisions (n = 81). Compared with the control group, individuals in the experimental groups avoided the advantageous CS + choice despite fewer gains. The predictor analysis further clarified that avoidant decisions were pronounced in highly trait anxious participants who exhibited higher fear responses. On the other hand, findings also indicated a reduction in absolute avoidance across the task. Combined, these findings demonstrate that fear conditioning can lead to avoidant decision making, especially in vulnerable individuals. The resulting costs parallel impairments caused by behavioral avoidance. Such an emotional decision-making style may be a link between aversive experience and the development of habitual pathological avoidance. Introducing rewards for approach, however, may counteract avoidant decisions.

Dimensional assessment of anxiety disorders in parents and children for DSM-5.

The current shift in the DSM towards the inclusion of a dimensional component allows clinicians and researchers to demonstrate not only the presence or absence of psychopathology in an individual, but also the degree to which the disorder and its symptoms are manifested. This study evaluated the psychometric properties and utility of a set of brief dimensional scales that assess DSM-based core features of anxiety disorders, for children and their parents. The dimensional scales and the Screen for Child Anxiety Related Emotional Disorders (SCARED-71), a questionnaire to assess symptoms of all anxiety disorders, were administered to a community sample of children (n = 382), aged 8-13 years, and their mothers (n = 285) and fathers (n = 255). The dimensional scales assess six anxiety disorders: specific phobia, agoraphobia, panic disorder, social anxiety disorder, generalized anxiety disorder, and separation anxiety disorder. Children rated their own anxiety and parents their child's anxiety. The dimensional scales demonstrated high internal consistency (α > 0.78, except for father reported child panic disorder, for reason of lack of variation), and moderate to high levels of convergent validity (rs = 0.29-0.73). Children who exceeded the SCARED cutoffs scored higher on the dimensional scales than those who did not, providing preliminary support for the clinical sensitivity of the scales. Given their strong psychometric properties and utility for both child and parent report, addition of the dimensional scales to the DSM-5 might be an effective way to incorporate dimensional measurement into the categorical DSM-5 assessment of anxiety disorders in children.

Perceived social support mediates anxiety and depressive symptom changes following primary care intervention.

BACKGROUND: The current study tested whether perceived social support serves as a mediator of anxiety and depressive symptom change following evidence-based anxiety treatment in the primary care setting. Gender, age, and race were tested as moderators. METHODS: Data were obtained from 1004 adult patients (age M = 43, SD = 13; 71% female; 56% White, 20% Hispanic, 12% Black) who participated in a randomized effectiveness trial (coordinated anxiety learning and management [CALM] study) comparing evidence-based intervention (cognitive-behavioral therapy and/or psychopharmacology) to usual care in the primary care setting. Patients were assessed with a battery of questionnaires at baseline, as well as at 6, 12, and 18 months following baseline. Measures utilized in the mediation analyses included the Abbreviated Medical Outcomes (MOS) Social Support Survey, the Brief Symptom Index (BSI)-Somatic and Anxiety subscales, and the Patient Health Questionnaire (PHQ-9). RESULTS: There was a mediating effect over time of perceived social support on symptom change following treatment, with stronger effects for 18-month depression than anxiety. None of the mediating pathways were moderated by gender, age, or race. CONCLUSIONS: Perceived social support may be central to anxiety and depressive symptom changes over time with evidence-based intervention in the primary care setting. These findings possibly have important implications for development of anxiety interventions.

Does a quality improvement intervention for anxiety result in differential outcomes for lower-income patients?

OBJECTIVE: The authors examined the effects of a collaborative care intervention for anxiety disorders in primary care on lower-income participants relative to those with higher incomes. They hypothesized that lower-income individuals would show less improvement or improve at a lower rate, given that they would experience greater economic stress over the treatment course. An alternative hypothesis was that lower-income participants would improve at a higher rate because the intervention facilitates access to evidence-based treatment, which typically is less available to persons with lower incomes. METHOD: Baseline demographic and clinical characteristics of patients with lower (N=287) and higher (N=717) income were compared using t tests and chi-square tests for continuous and categorical variables, respectively. For the longitudinal analysis of intervention effects by income group, the outcome measures were jointly modeled at baseline and at 6, 12, and 18 months by study site, income, time, intervention, time and intervention, income and time, income and intervention, and time, intervention, and income. RESULTS: Although lower-income participants were more ill and had greater disability at baseline than those with higher incomes, the two income groups were similar in clinical response. The lower-income participants experienced a comparable degree of clinical improvement, despite receiving fewer treatment sessions, less relapse prevention, and less continuous care. CONCLUSIONS: These findings contribute to the ongoing discussion as to whether or not, and to what extent, quality improvement interventions work equally well across income groups or require tailoring for specific vulnerable populations.

Anxiety treatment improves physical functioning with oblique scoring of the SF-12 short form health survey.

OBJECTIVE: No studies have found a positive effect of anxiety treatment on physical functioning, but recent investigations of the 12-item Short Form Health Questionnaire (SF-12), which is frequently used to assess physical functioning, have suggested that orthogonal scoring of the summary measure may distort representations of physical health. The current study reanalyzes whether anxiety treatment improves physical functioning using oblique scoring in the Coordinated Anxiety Learning and Management (CALM) randomized clinical trial for the treatment of anxiety disorders. Replication was tested in reanalysis of data from the earlier Collaborative Care for Anxiety and Panic (CCAP) randomized clinical trial for the treatment of panic disorder. METHOD: The CALM study included 1004 primary care patients with panic, social anxiety, generalized anxiety or posttraumatic stress disorders. Patients received usual care (UC) or an evidence-based intervention (cognitive behavioral therapy, psychotropic medication or both; ITV). Physical functioning (SF-12v2) was assessed at baseline and at 6, 12 and 18 months. Oblique and orthogonal scoring methods for the physical functioning aggregate measure from SF-12 scale items were compared. RESULTS: In CALM, physical functioning improved to a greater degree in ITV than UC for oblique but not orthogonal scoring. Findings were replicated in the CCAP data. CONCLUSIONS: Evidence-based treatment for anxiety disorders in primary care improves physical functioning when measured using oblique scoring of the SF-12. Due to this scoring issue, effects of mental health treatment on physical functioning may have been understated.

Implementation of the CALM intervention for anxiety disorders: a qualitative study.

BACKGROUND: Investigators recently tested the effectiveness of a collaborative-care intervention for anxiety disorders: Coordinated Anxiety Learning and Management(CALM) []) in 17 primary care clinics around the United States. Investigators also conducted a qualitative process evaluation. Key research questions were as follows: (1) What were the facilitators/barriers to implementing CALM? (2) What were the facilitators/barriers to sustaining CALM after the study was completed? METHODS: Key informant interviews were conducted with 47 clinic staff members (18 primary care providers, 13 nurses, 8 clinic administrators, and 8 clinic staff) and 14 study-trained anxiety clinical specialists (ACSs) who coordinated the collaborative care and provided cognitive behavioral therapy. The interviews were semistructured and conducted by phone. Data were content analyzed with line-by-line analyses leading to the development and refinement of themes. RESULTS: Similar themes emerged across stakeholders. Important facilitators to implementation included the perception of "low burden" to implement, provider satisfaction with the intervention, and frequent provider interaction with ACSs. Barriers to implementation included variable provider interest in mental health, high rates of part-time providers in clinics, and high social stressors of lower socioeconomic-status patients interfering with adherence. Key sustainability facilitators were if a clinic had already incorporated collaborative care for another disorder and presence of onsite mental health staff. The main barrier to sustainability was funding for the ACS. CONCLUSIONS: The CALM intervention was relatively easy to incorporate during the effectiveness trial, and satisfaction was generally high. Numerous implementation and sustainability barriers could limit the reach and impact of widespread adoption. Findings should be interpreted with the knowledge that the ACSs in this study were provided and trained by the study. Future research should explore uptake of CALM and similar interventions without the aid of an effectiveness trial.

Relationships among pain, anxiety, and depression in primary care.

Pain, anxiety, and depression are commonly seen in primary care patients and there is considerable evidence that these experiences are related. This study examined associations between symptoms of pain and symptoms and diagnoses of anxiety and depression in primary care patients. Results indicate that primary care patients who endorse symptoms of muscle pain, headache, or stomach pain are approximately 2.5-10 times more likely to screen positively for panic disorder, generalized anxiety disorder, or major depressive disorder. Endorsement of pain symptoms was also significantly associated with confirmed diagnoses of several of the anxiety disorders and/or major depression, with odds ratios ranging from approximately 3 to 9 for the diagnoses. Patients with an anxiety or depressive disorder also reported greater interference from pain. Similarly, patients endorsing pain symptoms reported lower mental health functioning and higher scores on severity measures of depression, social anxiety, and posttraumatic stress disorder. Mediation analyses indicated that depression mediated some, but not all of the relationships between anxiety and pain. Overall, these results reveal an association between reports of pain symptoms and not only depression, but also anxiety. An awareness of these relationships may be particularly important in primary care settings where a patient who presents with reports of pain may have an undiagnosed anxiety or depressive disorder.

Racial/ethnic differences in cortisol diurnal rhythms in a community sample of adolescents.

PURPOSE: To identify potential physiological pathways to racial disparities in health outcomes, this study uses cortisol data collected from a community sample of 255 adolescents to examine whether there are racial/ethnic differences in cortisol slopes and levels across the waking day in naturalistic settings. METHODS: This study uses salivary cortisol data (sampled five times per day over 3 days) to examine racial/ethnic differences in diurnal cortisol rhythms, while covarying the presence of major depressive disorder and chronic and episodic life stress (assessed by structured interviews), momentary negative emotion (reported in diaries completed with cortisol samples), and socioeconomic status, sleep, and health variables (assessed by questionnaire) previously found to be associated with cortisol levels. RESULTS: African-American and Hispanic youth were found to have flatter cortisol slopes across the waking day than their Caucasian counterparts. Differences are due to higher bedtime cortisol levels among Hispanics and to both lower wakeup and higher bedtime levels among African-Americans. Although higher levels of negative emotion were associated with flatter diurnal rhythms, the socioenvironmental factors examined failed to explain the observed racial/ethnic differences in diurnal cortisol rhythms. CONCLUSIONS: Significantly flatter diurnal cortisol slopes were found among African American and Hispanic adolescents, a pattern which has been related to negative health consequences. Further research is needed to examine how early these differences emerge and to identify their developmental origins. Although genetic contributions are possible, greater prenatal stress exposure, low birth weight, adverse early childhood experiences, experiences with racism or discrimination, and lifetime history of chronic stress are all reasonable psychosocial hypotheses to pursue.

Adherence to treatment among economically disadvantaged patients with panic disorder.

OBJECTIVE: The purpose of this study was to examine the feelings of disadvantaged patients about and experiences of treatment for anxiety disorders in primary care settings. METHODS: The patients had participated in the Collaborative Care for Anxiety and Panic study, which tested the effectiveness of an intervention to help primary care providers treat panic disorder. The treatment comprised cognitive behavioral therapy (CBT) combined with pharmacotherapy administered by primary care physicians with the expert advice of a psychiatrist. Post hoc semistructured interviews were conducted with 21 intervention participants who were classified according to adherence or nonadherence to treatment. The interview focused on reactions to CBT; reactions to the different features of the intervention, such as therapy sessions, demonstration videotapes, exercises, and a workbook; and comfort with the therapist. Two members of the research team independently coded, analyzed, and interpreted the data. RESULTS: Three themes emerged: information was empowering and reduced the sense of isolation experienced by participants, participants engaged in a dynamic and iterative personalized assessment of the intervention, and barriers to adherence were predominantly logistical. CONCLUSIONS: Results indicate that the extent to which patients chose to remain in treatment and follow treatment recommendations was rarely an all-or-nothing phenomenon. In a disadvantaged population such decisions seem to be influenced by the beliefs of the patient about what will and will not be effective in his or her individual case, an ongoing self-assessment of well-being, and the logistical barriers that come into play.

Functional impact and health utility of anxiety disorders in primary care outpatients.

OBJECTIVE: The objective of this study was to examine the relative impact of anxiety disorders and major depression on functional status and health-related quality of life of primary care outpatients. METHOD: Four hundred eighty adult outpatients at an index visit to their primary care provider were classified by structured diagnostic interview as having anxiety disorders (panic disorder with or without agoraphobia, social phobia, and posttraumatic stress disorder; generalized anxiety disorder was also assessed in a subset) with or without major depression. Functional status, sick days from work, and health-related quality of life (including a preference-based measure) were assessed using standardized measures adjusting for the impact of comorbid medical illnesses. Relative impact of the various anxiety disorders and major depression on these indices was evaluated. RESULTS: In multivariate regression analyses simultaneously adjusting for age, sex, number of chronic medical conditions, education, and/or poverty status, each of major depression, panic disorder, posttraumatic stress disorder, and social phobia contributed independently and relatively equally to the prediction of disability and functional outcomes. Generalized anxiety disorder had relatively little impact on these indices when the effects of comorbid major depression were considered. Overall, anxiety disorders were associated with substantial decrements in preference-based health states. CONCLUSIONS: These observations demonstrate that the presence of each of 3 common anxiety disorders (ie, panic disorder, posttraumatic stress disorder, and social phobia)-over and above the impact of chronic physical illness, major depression, and other socioeconomic factors-contributes in an approximately additive fashion to the prediction of poor functioning, reduced health-related quality of life, and more sick days from work. Greater awareness of the deleterious impact of anxiety disorders in primary care is warranted.

Assessment of beliefs about psychotropic medication and psychotherapy: development of a measure for patients with anxiety disorders.

OBJECTIVE: This study presents the psychometric properties of a brief measure to assess beliefs about psychotropic medications and psychotherapy among patients with anxiety disorders. METHOD: Data were collected on a large sample of primary care patients with a range of anxiety disorders, as part of the Collaborative Care for Anxiety and Panic study. Factor analyses using principal axis factoring with Varimax rotations were used to determine the factor structure of the beliefs scale. Internal consistency, concurrent validity and predictive validity of the resulting subscales were examined. RESULTS: Two subscales emerged, one reflecting beliefs about psychotropic medications and the other assessing beliefs about psychotherapy. Both showed strong internal consistency and concurrent validity. The beliefs about psychotropic medication demonstrated strong predictive validity. CONCLUSIONS: This measure may be a useful tool for assessing treatment beliefs among patients with anxiety disorders toward the provision of more quality treatment for this population. Its brevity may make it particularly useful in primary health care settings.

Perceived unmet need for mental health treatment and barriers to care among patients with panic disorder.

OBJECTIVE: This study estimated the extent of perceived unmet need for mental health treatment among individuals with panic disorder in primary care settings, investigated the determinants of unmet need, and assessed barriers to care. METHODS: Data were from baseline interviews in a clinical trial that investigated primary care treatment of panic disorder. Participants were asked whether there was any time in the past three months when they did not get as much care for emotional or personal problems as they needed or whether they had delays in getting care. Patients who endorsed unmet need were asked about specific perceived barriers. Logistic regression was used to investigate the determinants of unmet need. RESULTS: Of the 231 patients eligible for the study, 88 (38 percent) endorsed unmet need for emotional or mental health problems. Individuals with worse mental health, those who were more worried about panic, and those without sick pay were significantly more likely to report unmet need. Commonly reported barriers included being unable to find out where to go for help (43 percent), worry about cost (40 percent), lack of coverage by health plan (35 percent), and being unable to get an appointment soon enough (35 percent). CONCLUSIONS: The relatively low level of patient-reported unmet need for mental health treatment among primary care patients with panic disorder suggests that efforts to improve treatment of panic disorder should include patient education about mental illness and the effective treatments available. Although discussion of barriers to care has traditionally centered on stigma and economic factors, the results of this study suggest that simple logistic factors, such as not knowing whom to call for help, are also important barriers.

Beliefs about psychotropic medication and psychotherapy among primary care patients with anxiety disorders.

Primary health care clinics are increasingly providing psychiatric/psychological treatment of anxiety disorders, particularly for patients who do not have adequate access to specialty mental health services. Adequate treatment requires knowledge of and attention to patients' beliefs about available treatment options. The current investigation examined beliefs about psychotropic medications and psychotherapy among a sample of primary care patients with anxiety disorders. The influence of key demographic variables on strength of these beliefs was also explored. The presence of specific anxiety disorders was not found to impact strength of beliefs about either type of treatment. In contrast, there was a trend for the presence of depression to relate to more favorable attitudes toward psychotropic medication. Consistent with previous studies, ethnic minority patients reported less favorable attitudes toward both psychotropic medications and psychotherapy. These findings underscore the importance of assessing patient beliefs prior to the initiation of either psychotropic medications or psychotherapy across diagnostic and demographic groups. Practitioners should be particularly alert to the possibility that patients with anxiety disorders and members of ethnic minority groups may have less favorable attitudes toward treatment options. Treatment adherence may therefore be increased by addressing these beliefs directly.

Assessment and treatment of nocturnal panic attacks.

Nocturnal panic (NP), waking from sleep in a state of panic, is a common occurrence among patients with panic disorder, with 44-71% reporting at least one such attack. NP is a non-REM event that is distinct from sleep terrors, sleep apnea, nightmares or dream-induced arousals. This review outlines recent advances in the characterization of NP, as well as current approaches to the assessment and treatment of NP. In contrast to earlier work, more recent studies suggest that patients with NP do not differ from patients without NP on sleep architecture, sleep physiology, self-reported sleep quality and severity of panic disorder. However, more precise measurement of physiological precipitants and features is warranted. Assessment of NP focuses on ruling out other explanations for NP, with differential diagnosis based on interviews, sleep polysomnography and ambulatory recording of sleep. Psychological treatment (cognitive-behavioral therapy) targets misappraisals of anxiety sensations, hyperventilatory response, and conditioned reactions to internal, physical cues. Recent evidence supports the efficacy of this approach, however, controlled studies on pharmacological agents in the treatment of NP are lacking. Research is needed to examine the effects of combined cognitive-behavioral therapy and medications, compared to medication alone in the treatment of NP.

Use of herbal medicine in primary care patients with mood and anxiety disorders.

Studies have documented the increasing use of complementary and alternative medicine over the last decade, especially in distressed individuals with symptoms of anxiety, depression, and pain. Herbal medicine is a specific form of complementary and alternative medicine often used by individuals seeing traditional medical practitioners and, hence, has the potential to interact with other medically prescribed treatments. The study examined the use of herbal medicine in a group of primary care patients with symptoms of anxiety and depression. The rate of use of herbal medicines was 11%, and use was selectively associated with a diagnosis of major depression, higher education, and a lower burden of medical illness. Use was not associated with receipt of pharmacotherapy or psychotherapy for anxiety or depression.
