RESUMO

Sleep disturbances are present in ~65% of individuals with generalised anxiety disorder (GAD). Although both Kundalini yoga (KY) and cognitive behavioural therapy (CBT) are effective treatment options for GAD, little is known about how these treatments compare in improving sleep for GAD and what drives these changes. Accordingly, we examined the effects of CBT, KY, and stress education (SEdu; an attention control condition) on subjective sleep quality (as measured by the Pittsburgh Sleep Quality Index [PSQI] and Insomnia Severity Index [ISI]) in a randomised controlled trial of 226 adults with GAD (mean age 33.37 years; 70% female; 79% White). We hypothesised that both CBT and KY would outperform SEdu in improving sleep disturbances. Three potential mediators of sleep improvement (worry, mindfulness, perceived stress) were also examined. In line with hypotheses, PSQI and ISI scores significantly improved from pre- to post-treatment for all three treatment groups (all p < 0.001, all d > 0.97). However, contrary to predictions, sleep changes were not significantly greater for CBT or KY compared to SEdu. In mediation analyses, within-person deviations in worry, mindfulness, and stress each significantly mediated the effect of time on sleep outcomes. Degree of change in sleep attributable to worry (CBT > KY > SEdu) and perceived stress (CBT, KY > SEdu) was moderated by treatment group. Personalised medicine as well as combined treatment approaches should be studied to help reduce sleep difficulties for patients with GAD who do not respond.

RESUMO

Little is known about central nervous system (CNS) responses to emotional stimuli in asthma. Nitric oxide in exhaled breath (FENO) is elevated in asthma due to allergic immune processes, but endogenous nitric oxide is also known to modulate CNS activity. We measured fMRI blood oxygen-dependent (BOLD) brain activation to negative (blood-injection-injury themes) and neutral films in 31 participants (15 with asthma). Regions-of-interest analysis was performed on key areas relevant to central adaptive control, threat processing, or salience networks, with dorsolateral prefrontal cortex (PFC), anterior insula, dorsal anterior cingulate cortex (dACC), amygdala, ventral striatum, ventral tegmentum, and periaqueductal gray, as well as top-down modulation of emotion, with ventrolateral and ventromedial PFC. Both groups showed less BOLD deactivation from fixation cross-baseline in the left anterior insula and bilateral ventromedial PFC for negative than neutral films, and for an additional number of areas, including the fusiform gyrus, for film versus recovery phases. Less deactivation during films followed by less recovery from deactivation was found in asthma compared to healthy controls. Changes in PCO2 did not explain these findings. FENO was positively related to BOLD activation in general, but more pronounced in healthy controls and more likely in neutral film processing. Thus, asthma is associated with altered processing of film stimuli across brain regions not limited to central adaptive control, threat processing, or salience networks. Higher levels of NO appear to facilitate CNS activity, but only in healthy controls, possibly due to allergy's masking effects on FENO.

RESUMO

BACKGROUND: Affective response to exercise (i.e., how individuals feel during- and post-exercise) as well as post-behavioral evaluations of affective experiences with exercise (i.e., reflecting on the experience after engaging in exercise) may be important determinants of regular exercise. PURPOSE: We compared post-exercise affective response and post-behavioral evaluations of exercise between a physically active and underactive group. Physically active (n = 32) and underactive (n = 25) participants completed a 10-minute treadmill bout of vigorous exercise and reported affective valence, positive activated affect, negative activated affect, calmness, fatigue and relief at various points during and/or after the bout. RESULTS: As expected, both groups reported an improvement in affective valence immediately post-exercise (ps < 0.001). This improvement in affective valence was associated with a concurrent decrease in negative affect (ps < 0.05) for the physically underactive group and was only associated with a concurrent increase in positive affect (ps < 0.02) for the active group. There were significant differences between physically active and underactive groups in pre-post exercise changes in positive activated affect (ps < 0.005). The underactive group reported greater relief than the active group at all-post exercise time-points (ps < 0.05). CONCLUSIONS:  These findings have implications for understanding post-exercise affective response and post-behavioral evaluations of exercise and for interventions directed at influencing the post-exercise affective response and behavioral evaluations of exercise in physically underactive individuals.

RESUMO

OBJECTIVE: Anxiety is highly prevalent in individuals with asthma. Asthma symptoms and medication can exacerbate anxiety, and vice versa. Unfortunately, treatments of comorbid anxiety and asthma are largely lacking. A problematic feature common to both conditions is hyperventilation. It adversely affects lung function and symptoms in asthma and anxiety. We examined whether a treatment to reduce hyperventilation, shown to improve asthma symptoms, also improves anxiety in asthma patients with high anxiety. METHOD: One hundred twenty English- or Spanish-speaking adult patients with asthma were randomly assigned to either Capnometry-Assisted Respiratory Training (CART) to raise P co2 or feedback to slow respiratory rate (SLOW). Although anxiety was not an inclusion criterion, 21.7% met clinically relevant anxiety levels on the Hospital Anxiety and Depression Scale (HADS). Anxiety (HADS-A) and depression (HADS-D) scales, anxiety sensitivity (Anxiety Sensitivity Index [ASI]), and negative affect (Negative Affect Scale of the Positive Affect Negative Affect Schedule) were assessed at baseline, posttreatment, 1-month follow-up, and 6-month follow-up. RESULTS: In this secondary analysis, asthma patients with high baseline anxiety showed greater reductions in ASI and PANAS-N in CART than in SLOW ( p values ≤ .005, Cohen d values ≥ 0.58). Furthermore, at 6-month follow-up, these patients also had lower ASI, PANAS-N, and HADS-D in CART than in SLOW ( p values ≤ .012, Cohen d values ≥ 0.54). Patients with low baseline anxiety did not have differential outcomes in CART than in SLOW. CONCLUSIONS: For asthma patients with high anxiety, our brief training designed to raise P co2 resulted in significant and sustained reductions in anxiety sensitivity and negative affect compared with slow-breathing training. The findings lend support for P co2 as a potential physiological target for anxiety reduction in asthma. TRIAL REGISTRATION: Clinicaltrials.gov Identifier: NCT00975273 .

RESUMO

People with asthma may be particularly vulnerable to pandemic-related psychological distress, and research is needed to understand the impact of the coronavirus disease 19 (COVID-19) pandemic on their health and well-being. We sought to study the well-being of people with asthma relative to non-asthmatic controls during the COVID-19 pandemic. We also investigated asthma symptoms and COVID-19-related anxiety as potential mediators of distress. Participants completed self-report measures of psychological functioning, including anxiety, depression, stress, and burnout. Controlling for potential confounds, multiple-regression analyses examined differences in psychological health between people with and without asthma. Mediator analyses investigated the role of asthma symptoms and COVID-19-related anxiety in this relationship. 234 adults (111 with asthma, 123 without) participated in an online survey from July to November 2020. During this time, people with asthma reported higher levels of anxiety, perceived stress, and burnout symptoms compared to controls. Elevations in burnout symptoms were found beyond general anxiety and depression (sr2 = .03, p < .001). Reported symptoms typical in both asthma and COVID-19 partially mediated this relationship (Pm = .42, p < .05). People with asthma reported unique psychological challenges during the COVID-19 pandemic including elevated burnout symptoms. Experience of asthma symptoms played a key role in vulnerability to emotional exhaustion. Clinical implications include increased attention to asthma symptom burden within the context of heightened environmental stress and restricted healthcare access.

RESUMO

OBJECTIVE: Effectiveness trials aim to increase the generalizability and public health impact of interventions. However, challenges associated with this design present threats to external and internal validity. This paper illustrates these challenges using data from a two-site randomized effectiveness trial, the Community Study of Outcome Monitoring for Emotional Disorders in Teens (COMET) and presents recommendations for future research. METHOD: COMET was a randomized effectiveness trial conducted in 19 community mental health clinics in two states comparing three interventions: treatment as usual (TAU), TAU with measurement-based care (TAU+), and the Unified Protocol forTransdiagnostic Treatment of Emotional Disorders in Adolescents with MBC (UPA). Participants included 176 clinicians (mean age = 35.5; 85.8% cisgender female; 53.0% racially and/or ethnically minorized) and 196 adolescents (mean age = 14.7; 65.3% cisgender female; 69.4% racially and/or ethnically minorized). Analyses outlined participant flow from recruitment to study completion, described participant characteristics, and examined site differences. RESULTS: Analysis of participant flow suggested that recruitment and retention of clinicians and adolescents was challenging, raising questions about whether participants were representative of participating clinics. Both the clinician and adolescent samples were racially and ethnically diverse and adolescents were low income and clinically complex. Significant site differences were observed in clinician and adolescent characteristics. CONCLUSIONS: While this study was successful in recruiting a diverse and historically under-represented sample, difficulties in recruitment and retention raise questions about external validity and site differences present challenges to internal validity of study findings. Suggestions for future effectiveness studies, drawing from implementation science approaches, are discussed.

RESUMO

Many individuals have experienced a multitude of chronic stressors and diminished psychological functioning during COVID-19. The current study examined whether biases towards positive social media or positive autobiographical memories was related to increases in psychological functioning during COVID-19. Participants were 1071 adults (Mage = 46.31; 58% female; 78% White) recruited from MTurk. Participants reported on their social media consumption and autobiographical recall, positive and negative affect, and dysphoria symptoms. Results indicated that, at the first assessment collected in the spring and summer of 2020, positively biased social media consumption was cross-sectionally related to higher levels of positive affect, and positively biased autobiographical recall was cross-sectionally related to lower levels of negative affect and dysphoria symptoms. Sensitivity analyses examined cross-sectional relations from a second assessment collected in fall 2020, and prospective cross-lagged analyses. The findings point to potential psychological benefits of positive biases during chronic stressors.

RESUMO

INTRODUCTION: Poor sleep is prevalent among individuals with social anxiety disorder (SAD) and may negatively affect exposure therapy outcomes. Poor sleep may impair memory and learning, and thus compromise fear extinction learning thought to take place in exposure therapy. We examined poor sleep as a predictor of exposure therapy outcomes for SAD and the moderating role of d-cycloserine (DCS) on this relationship. METHODS: Participants were 152 individuals with a primary diagnosis of SAD. As part of a randomized clinical trial evaluating the efficacy of DCS for enhancing the effects of exposure therapy, they completed self-report baseline measure of sleep quality, and self-report sleep diaries assessing sleep duration (total sleep time [TST]) and sleep quality the nights before and after treatment sessions. RESULTS: Poorer baseline sleep quality was significantly associated with slower improvement over time and worse symptom outcomes at the end of treatment and follow-up after controlling for baseline symptoms of depression and social anxiety. Greater TST the night before treatment predicted lower SAD symptoms at the next session, after controlling for symptoms at the previous session. There was no relation between prior or subsequent night sleep quality on symptoms at the next session. No associations were moderated by DCS. CONCLUSIONS: We replicated and extended findings indicating that poor sleep quality is associated with poorer exposure therapy outcomes for SAD. Assessing for sleep difficulties before treatment initiation and incorporating sleep interventions into treatment may enhance exposure therapy outcomes for SAD.

RESUMO

Initial evidence suggests that experiential avoidance (EA) mediates the relation between anxiety sensitivity (AS) and depression. We examined the AS-EA-depression pathway, examining both concurrent, and prospective (cross-lag), mediation models. Utilizing data from a study that examined the effects of exercise on AS (N = 60), we modeled depressive symptoms, EA, and AS over four time points. Time-varying predictors were disaggregated into between-subjects (each person's mean level of the predictor) and within-subjects change (each person's deviations, at each time point, from their mean level on the predictor) components. Tests of the concurrent relations were partially consistent with predictions, with mean EA levels, but not within-subjects changes in EA, partially mediating the relation between AS and depression symptom severity. However, the prospective, cross-lag mediation model, in which AS predicted future EA controlling for previous EA, and EA predicted future depression, controlling for previous depression, yielded no significant effects. These results suggest that observed between-subjects mediation findings, found here and in previous studies, may not replicate using more stringent, quasi-causal, cross-lag mediation analyses. These results highlight the importance of estimating causal pathways in mediation analyses. Clinical implications and directions for future research are discussed.

RESUMO

The present study aimed to replicate the finding that younger age predicts higher pre quit-day attrition. Our second aim was to explain this relation by examining empirically and theoretically informed age-related risk factors for low smoking cessation treatment engagement. 136 participants (Mage = 44.2 years, SD = 11.3 years; age = 22-64 years) were randomized to 15-weeks of either 1) an exercise intervention (n = 72) or 2) a wellness education control condition (n = 64). First, a logistic regression analysis was employed to test whether younger adults were more likely than older adults to drop prior to quit date. Next, we assessed whether smoking related health concerns, social expectancies, and/or perceived severity of craving affected the strength of the relation between age and attrition, by adding these three variables to the logistic regression along with age. The logistic regression model indicated that younger age and treatment condition were significantly related to the odds of dropping from treatment prior to the scheduled quit date. Further, health concerns, social expectancies, and/or perceived severity of cravings did not account for the effect of age on pre quit-day attrition. These findings highlight the importance of identifying empirically and theoretically informed variables associated with the pre quit-day attrition problem of young smokers.

RESUMO

Children's contact with their mother's violent partner is a potentially important variable for understanding conduct problems among children exposed to intimate partner violence (IPV). Within the context of a treatment study evaluating a parenting intervention (Project Support) for families exiting a domestic violence shelter, this study tested four hypotheses regarding children's postshelter contact with their mother's violent partner: (1) participation in Project Support decreases the frequency of children's contact with their mother's violent partner; (2) postshelter contact is positively associated with children's conduct problems and is associated more strongly for girls than boys; (3) frequency of contact mediates Project Support's effects on children's conduct problems; and (4) frequency of contact is positively associated with IPV and partner-child aggression, and these latter associations help explain effects of contact on children's conduct problems. Participants were 66 women (26 White) with a child (32 girls) between 4 and 9 years. Families were assessed every 4 months for 20 months after departure from a domestic violence shelter. Project Support reduced the extent of partner-child contact. In addition, within-subject changes in contact over time were associated with girls', but not boys', conduct problems, and it partially mediated effects of Project Support on girls' conduct problems. Higher average levels of contact over time were also positively associated with further incidents of IPV and partner-child aggression, and partner-child aggression helped explain effects of contact on children's conduct problems. Children's postshelter contact with the mother's violent partner relates positively to several negative family outcomes.

RESUMO

Importance: Effective and efficient treatment is needed for posttraumatic stress disorder (PTSD) in active duty military personnel. Objective: To examine the effects of massed prolonged exposure therapy (massed therapy), spaced prolonged exposure therapy (spaced therapy), present-centered therapy (PCT), and a minimal-contact control (MCC) on PTSD severity. Design, Setting, and Participants: Randomized clinical trial conducted at Fort Hood, Texas, from January 2011 through July 2016 and enrolling 370 military personnel with PTSD who had returned from Iraq, Afghanistan, or both. Final follow-up was July 11, 2016. Interventions: Prolonged exposure therapy, cognitive behavioral therapy involving exposure to trauma memories/reminders, administered as massed therapy (n = 110; 10 sessions over 2 weeks) or spaced therapy (n = 109; 10 sessions over 8 weeks); PCT, a non-trauma-focused therapy involving identifying/discussing daily stressors (n = 107; 10 sessions over 8 weeks); or MCC, telephone calls from therapists (n = 40; once weekly for 4 weeks). Main Outcomes and Measures: Outcomes were assessed before and after treatment and at 2-week, 12-week, and 6-month follow-up. Primary outcome was interviewer-assessed PTSD symptom severity, measured by the PTSD Symptom Scale-Interview (PSS-I; range, 0-51; higher scores indicate greater PTSD severity; MCID, 3.18), used to assess efficacy of massed therapy at 2 weeks posttreatment vs MCC at week 4; noninferiority of massed therapy vs spaced therapy at 2 weeks and 12 weeks posttreatment (noninferiority margin, 50% [2.3 points on PSS-I, with 1-sided α = .05]); and efficacy of spaced therapy vs PCT at posttreatment. Results: Among 370 randomized participants, data were analyzed for 366 (mean age, 32.7 [SD, 7.3] years; 44 women [12.0%]; mean baseline PSS-I score, 25.49 [6.36]), and 216 (59.0%) completed the study. At 2 weeks posttreatment, mean PSS-I score was 17.62 (mean decrease from baseline, 7.13) for massed therapy and 21.41 (mean decrease, 3.43) for MCC (difference in decrease, 3.70 [95% CI,0.72 to 6.68]; P = .02). At 2 weeks posttreatment, mean PSS-I score was 18.03 for spaced therapy (decrease, 7.29; difference in means vs massed therapy, 0.79 [1-sided 95% CI, -∞ to 2.29; P = .049 for noninferiority]) and at 12 weeks posttreatment was 18.88 for massed therapy (decrease, 6.32) and 18.34 for spaced therapy (decrease, 6.97; difference, 0.55 [1-sided 95% CI, -∞ to 2.05; P = .03 for noninferiority]). At posttreatment, PSS-I scores for PCT were 18.65 (decrease, 7.31; difference in decrease vs spaced therapy, 0.10 [95% CI, -2.48 to 2.27]; P = .93). Conclusions and Relevance: Among active duty military personnel with PTSD, massed therapy (10 sessions over 2 weeks) reduced PTSD symptom severity more than MCC at 2-week follow-up and was noninferior to spaced therapy (10 sessions over 8 weeks), and there was no significant difference between spaced therapy and PCT. The reductions in PTSD symptom severity with all treatments were relatively modest, suggesting that further research is needed to determine the clinical importance of these findings.

RESUMO

Calcium-binding protein spermatid-specific 1 (CABS1) is expressed in the human submandibular gland and has an anti-inflammatory motif similar to that in submandibular rat 1 in rats. Here, we investigate CABS1 in human saliva and its association with psychological and physiological distress and inflammation in humans. Volunteers participated across three studies: 1) weekly baseline measures; 2) a psychosocial speech and mental arithmetic stressor under evaluative threat; and 3) during academic exam stress. Salivary samples were analyzed for CABS1 and cortisol. Additional measures included questionnaires of perceived stress and negative affect; exhaled nitric oxide; respiration and cardiac activity; lung function; and salivary and nasal inflammatory markers. We identified a CABS1 immunoreactive band at 27 kDa in all participants and additional molecular mass forms in some participants. One week temporal stability of the 27-kDa band was satisfactory (test-retest reliability estimate = 0.62-0.86). Acute stress increased intensity of 18, 27, and 55 kDa bands; 27-kDa increases were associated with more negative affect and lower heart rate, sympathetic activity, respiration rate, and minute ventilation. In both acute and academic stress, changes in 27 kDa were positively associated with salivary cortisol. The 27-kDa band was also positively associated with VEGF and salivary leukotriene B4 levels. Participants with low molecular weight CABS1 bands showed reduced habitual stress and negative affect in response to acute stress. CABS1 is readily detected in human saliva and is associated with psychological and physiological indicators of stress. The role of CABS1 in inflammatory processes, stress, and stress resilience requires careful study.

RESUMO

OBJECTIVE: Stress is associated with the maintenance of eating disorders and exercise behaviors. However, it is unclear how stress is associated with exercise and vice-versa among individuals with higher levels of eating disorder symptoms in daily life. The current study tested the moderating effect of eating disorder symptoms on the relationships between (1) daily stress and later exercise behavior and (2) daily exercise behavior and later stress. METHOD: Female college students [N = 129, mean age = 19.19 (SD = 1.40)] completed the Eating Disorder Inventory-2. Participants then completed measures of stress and exercise four times daily across seven days using an automated telephone ecological momentary assessment system. Data were analyzed using multilevel models. RESULTS: Drive for thinness, bulimic symptoms, and body dissatisfaction significantly moderated the relationship between daily stress and later exercise (ps = .01-.05), such that higher daily stress predicted higher later exercise only in individuals who were low (but not average or high) in drive for thinness, bulimic symptoms, and body dissatisfaction symptoms. DISCUSSION: Stress is associated with exercise differentially depending on individuals' eating disorder symptoms. Our findings suggest that only individuals with lower levels of eating disorder symptoms exercise when stressed.

RESUMO

Although bystander programs to prevent relationship and sexual violence have been evaluated with college students, few evaluations have been conducted with high school students. This study evaluated the effectiveness of TakeCARE, a brief video bystander program designed to promote helpful bystander behavior in situations involving relationship violence among high school students. Students (N = 1295; 52.5% female; 72.3% Hispanic) reported their bystander behavior at a baseline assessment. Classrooms (N = 66) were randomized to view TakeCARE or to a control condition, and high school counselors administered the video in the classrooms assigned to view TakeCARE. Students again reported their bystander behavior at a follow-up assessment approximately 3 months afterward. Results indicate that students who viewed TakeCARE reported more helpful bystander behavior at the follow-up assessment than students in the control condition. Results of exploratory analyses of the likelihood of encountering and intervening upon specific situations calling for bystander behavior are also reported. TakeCARE is efficacious when implemented in an urban high school by high school counselors.

RESUMO

OBJECTIVES: High anxiety sensitivity predicts poor smoking cessation outcomes. Aerobic exercise reduces anxiety sensitivity and aspects of the risk conferred by anxiety sensitivity. In the current study, we examined whether exercise can aid smoking cessation in adults with high anxiety sensitivity. METHODS: Participants were sedentary and low-activity adult daily smokers (n = 136) with elevated prescreen anxiety sensitivity. Participants received 15 weeks of standard smoking cessation treatment (ST; cognitive behavioral therapy plus nicotine replacement therapy). In addition, participants were simultaneously randomized to 15 weeks of either an exercise intervention (ST + EX; n = 72) or a wellness education control condition (ST + CTRL; n = 64). Self-reported smoking abstinence was assessed weekly during the intervention, at the end of treatment (10 weeks after the target quit date), and at 4 and 6 months after the target quit date. Abstinence was verified by expired carbon monoxide readings and saliva cotinine. RESULTS: Results indicated that point prevalence abstinence (PPA) and prolonged abstinence (PA) rates were significantly higher for ST + EX than for ST + CTRL at each of the major end points among persons with high anxiety sensitivity (PPA: b = -0.91, standard error [SE] = 0.393, t(1171) = -2.33, p = .020; PA: b = -0.98, SE = 0.346, t(132) = -2.84, p = .005), but not among those with low anxiety sensitivity (PPA: b = -0.23, SE = 0.218, t(1171) = -1.06, p = .29; PA: b = -0.31, SE = 0.306, t(132) = -1.01, p = .32). CONCLUSIONS: The present results suggest that exercise facilitates the odds of quit success for smokers with high levels of anxiety sensitivity and therefore may be a useful therapeutic tactic for this high-risk segment of the smoking population.

RESUMO

OBJECTIVES: Anxiety sensitivity (AS) is associated with poor smoking cessation outcomes. One reason may be that smokers with high AS smoke differently (i.e., to manage negative affect and uncomfortable bodily sensations) than other smokers, leading to stronger addiction (due to an affect/sensation based and thereby highly variable rather than a regular smoking routine). Thus, we examined the relationship between AS and smoking variability in a group of treatment-seeking smokers. METHODS: Participants (N = 136; 52.2% female; Mage = 44.19 years, SD = 11.29) were daily smokers with elevated AS (AS≥20 on the Anxiety Sensitivity Index 16-item at prescreen) recruited as part of a larger randomized controlled trial for smoking cessation. Most participants were Caucasian (73%), educated (with 76% attending some college), unmarried (73%), and employed full-time (56%). They smoked, on average, 17 cigarettes per day. RESULTS: Consistent with prediction, a regression analysis of baseline assessments and a longitudinal analysis with multilevel modeling (MLM) both showed higher AS was associated with greater variability in cigarettes smoked per day while controlling for gender, age, ethnicity, and income. CONCLUSIONS: This finding encourages investigation of how AS might interact with clinical strategies using a fixed smoking taper as part of quit attempts.

RESUMO

BACKGROUND: The present study examined the effects of homework compliance on outcome from cognitive behavioral therapy (CBT) for children with obsessive-compulsive disorder (OCD) and the extent to which these effects differ as a function of augmentation of CBT with D-cycloserine (DCS). METHODS: Twenty-seven youth with OCD were randomized to either 50 mg DCS or placebo (PBO) administered immediately after each of 10 CBT sessions, primarily consisting of exposure and ritual prevention (ERP). Independent evaluators assessed OCD severity using the Children's Yale-Brown Obsessive-Compulsive Scale (CY-BOCS) at the start of each session. Compliance with between-session ERP assignments was also assessed at the start of each session using the Patient ERP Adherence Scale (PEAS). RESULTS: Greater homework compliance between the previous session and the current session was related to lower CY-BOCS at the current session. However, the relation between homework compliance and CY-BOCS varied by treatment condition. Higher homework compliance was related to lower CY-BOCS for participants in the DCS condition, but not for participants in the PBO condition. Furthermore, participants receiving DCS were estimated to have significantly lower CY-BOCS than those given PBO among those with the highest levels of homework compliance. CONCLUSIONS: DCS may more effectively facilitate the effects of CBT for youth with OCD when patients are compliant with prescribed homework. Theoretical and clinical implications are discussed.

RESUMO

The current study examined how interpersonal racial discrimination experiences operate together with other forms of interpersonal violence to contribute to mental health symptoms among justice-involved adolescents of color. Participants were 118 justice-involved adolescents of color aged 14 to 17 (M = 15.77, SD = 1.08; 52.5% male; 77.1% Black/African American) and their mothers. At baseline, adolescents reported on experiences of interpersonal racial discrimination, harsh parenting, teen dating violence, and exposure to interparental physical intimate partner violence. At baseline and the 3-month follow-up assessment, adolescents reported on trauma symptoms, and adolescents and their mothers reported on the adolescents' externalizing and internalizing symptoms. Multivariate multilevel modeling results indicated that interpersonal racial discrimination experiences contributed additively to adolescent mental health symptoms at both the baseline and 3-month follow-up assessments, after accounting for exposure to other forms of interpersonal violence. The current findings highlight the importance of considering adolescents' experiences of interpersonal racial discrimination, together with other forms of interpersonal violence, in work focused on understanding the mental health symptoms of justice-involved adolescents of color.
