OBJECTIVE: Patient treatment preference may moderate treatment effect in major depressive disorder (MDD) studies. Little research has addressed preference in posttraumatic stress disorder (PTSD); almost none has assessed actual patients' PTSD psychotherapy preferences. From a 14-week trial of chronic PTSD comparing prolonged exposure, relaxation therapy, and interpersonal psychotherapy, we report treatment preferences of the 110 randomized patients, explore preference correlates, and assess effects on treatment outcome. METHOD: Patients recruited between 2008 and 2013 with chronic DSM-IV PTSD (Clinician-Administered PTSD Scale [CAPS] score >/= 50) received balanced, scripted psychotherapy descriptions prerandomization and indicated their preferences. Analyses assessed relationships of treatment attitudes to demographic and clinical factors. We hypothesized that patients randomized to preferred treatments would have better outcomes, and to unwanted treatment worse outcomes. RESULTS: Eighty-seven patients (79%) voiced treatment preferences or disinclinations: 29 (26%) preferred prolonged exposure, 29 (26%) preferred relaxation therapy, and 56 (50%) preferred interpersonal psychotherapy (Cochran Q = 18.46, P < .001), whereas 29 (26%) were disinclined to prolonged exposure, 18 (16%) to relaxation therapy, and 3 (3%) to interpersonal psychotherapy (Cochran Q = 22.71, P < .001). Several baseline clinical variables correlated with treatment preferences. Overall, treatment preference/disinclination did not predict change in CAPS score, treatment response, or dropout. Comorbidly depressed patients receiving unwanted treatment had worse final CAPS scores. CONCLUSIONS: These exploratory findings are the first relating patients' PTSD psychotherapy preferences to outcome. Despite explanations emphasizing prolonged exposure's greater empirical support, patients significantly preferred interpersonal psychotherapy. Preference subtly affected psychotherapy outcome; depression appeared an important moderator of the effect of unwanted treatment on outcome. Potential biases to avoid in future research are discussed. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT00739765.

OBJECTIVES: Clinical neuroscience is increasingly turning to imaging the human brain for answers to a range of questions and challenges. To date, the majority of studies have focused on the neural basis of current psychiatric symptoms, which can facilitate the identification of neurobiological markers for diagnosis. However, the increasing availability and feasibility of using imaging modalities, such as diffusion imaging and resting-state fMRI, enable longitudinal mapping of brain development. This shift in the field is opening the possibility of identifying predictive markers of risk or prognosis, and also represents a critical missing element for efforts to promote personalized or individualized medicine in psychiatry (i.e., stratified psychiatry). METHODS: The present work provides a selective review of potentially high-yield populations for longitudinal examination with MRI, based upon our understanding of risk from epidemiologic studies and initial MRI findings. RESULTS: Our discussion is organized into three topic areas: (1) practical considerations for establishing temporal precedence in psychiatric research; (2) readiness of the field for conducting longitudinal MRI, particularly for neurodevelopmental questions; and (3) illustrations of high-yield populations and time windows for examination that can be used to rapidly generate meaningful and useful data. Particular emphasis is placed on the implementation of time-appropriate, developmentally informed longitudinal designs, capable of facilitating the identification of biomarkers predictive of risk and prognosis. CONCLUSIONS: Strategic longitudinal examination of the brain at-risk has the potential to bring the concepts of early intervention and prevention to psychiatry. (JINS, 2016, 22, 164-179).

Developmental ethanol exposure can lead to long-lasting cognitive impairment, hyperactivity, and emotional dysregulation among other problems. In healthy adults, sleep plays an important role in each of these behavioral manifestations. Here we explored circadian rhythms (activity, temperature) and slow-wave sleep in adult mice that had received a single day of ethanol exposure on postnatal day 7 and saline littermate controls. We tested for correlations between slow-wave activity and both contextual fear conditioning and hyperactivity. Developmental ethanol resulted in adult hyperactivity within the home cage compared to controls but did not significantly modify circadian cycles in activity or temperature. It also resulted in reduced and fragmented slow-wave sleep, including reduced slow-wave bout duration and increased slow-wave/fast-wave transitions over 24 hour periods. In the same animals, developmental ethanol exposure also resulted in impaired contextual fear conditioning memory. The impairment in memory was significantly correlated with slow-wave sleep fragmentation. Furthermore, ethanol treated animals did not display a post-training modification in slow-wave sleep which occurred in controls. In contrast to the memory impairment, sleep fragmentation was not correlated with the developmental ethanol-induced hyperactivity. Together these results suggest that disruption of slow-wave sleep and its plasticity are a secondary contributor to a subset of developmental ethanol exposure's long-lasting consequences.

OBJECTIVE: The aim of this analysis was to determine changes in patterns of depression screening and diagnosis over three years in primary and specialty mental health care in a large health maintenance organization (HMO) as part of a project to develop quality measures for adolescent depression treatment. METHODS: Two series of aggregate data (2010-2012) were gathered from the electronic health records of the HMO for 44,342 unique adolescents (ages 12 to 21) who had visits in primary and mental health care. Chi square tests assessed the significance of changes in frequency and departmental location of Patient Health Questionnaire-9 (PHQ-9) administration, incidence of depression symptoms, and depression diagnoses. RESULTS: There was a significant increase in PHQ-9 use, predominantly in primary care, consistent with internally generated organizational recommendations to increase screening with the PHQ-9. The increase in PHQ-9 use led to an increase in depression diagnoses in primary care and a shift in the location of some diagnoses from specialty mental health care to primary care. The increase in PHQ-9 use was also linked to a decrease in the proportion of positive PHQ-9 results that led to formal depression diagnoses. CONCLUSIONS: The rate of depression screening in primary care increased over the study period. This increase corresponded to an increase in the number of depression diagnoses made in primary care and a shift in the location in which depression diagnoses were made, from the mental health department to primary care. The frequency of positive PHQ-9 administrations not associated with depression diagnoses also increased.

Importance: Published guidelines describing effective adolescent depression care in primary care settings include screening, assessment, treatment initiation, and symptom monitoring. It is unclear the extent to which these steps are documented in patient health records. Objective: To determine rates of appropriate follow-up care for adolescents with newly identified depression symptoms in 3 large health systems. Design, Setting, and Participants: In this analysis conducted from March to September 2014, structured data retrospectively extracted from electronic health records were analyzed for 3 months following initial symptom identification to determine whether the patient was followed up and, if so, whether treatment was initiated and/or symptoms were monitored. Records were collected from 2 large health maintenance organizations in the western United States and a network of community health centers in the Northeast. The study group included adolescents (N = 4612) with newly identified depression symptoms, defined as an elevated score on the Patient Health Questionnaire (>/=10) and/or a diagnosis of depression. Main Outcomes and Measures: Rates of treatment initiation, symptom monitoring, and follow-up care documented within 3 months of initial symptom identification. Results: Among the 4612 participants, the mean (SD) age at index event was 16.0 (2.3) years, and 3060 were female (66%). Treatment was initiated for nearly two-thirds of adolescents (79% of those with a diagnosis of major depression; n = 1023); most received psychotherapy alone or in combination with medications. However, in the 3 months following identification, 36% of adolescents received no treatment (n = 1678), 68% did not have a follow-up symptom assessment (n = 3136), and 19% did not receive any follow-up care (n = 854). Further, 40% of adolescents prescribed antidepressant medication did not have any documentation of follow-up care for 3 months (n = 356). Younger age (ages 15-17 years: odds ratio [OR], 0.78; 95% CI, 0.67-0.92 and ages 18-20 years: OR, 0.83; 95% CI, 0.70-0.99; P = .008), more severe initial symptoms (moderate: OR, 0.99; 95% CI, 0.82-1.21; moderate to severe: OR, 1.46; 95% CI, 1.19-1.80; and severe: OR, 2.14; 95% CI, 1.65-2.79; P < .001), and receiving a diagnosis (major depression/dysthymia: OR, 2.65; 95% CI, 2.20-3.20 and unspecified depression/adjustment disorder: OR, 1.75; 95% CI, 1.43-2.14; P < .001) were significantly associated with treatment initiation. Differences in rates of follow-up care were evident between sites (site 2: OR, 1.77; 95% CI, 1.45-2.16 and site 3: OR, 2.10; 95% CI, 1.72-2.57), suggesting that differences within health systems may also affect care received. Conclusions and Relevance: Most adolescents with newly identified depression symptoms received some treatment, usually including psychotherapy, within the first 3 months after identification. However, follow-up care was low and substantial variation existed between sites. These results raise concerns about the quality of care for adolescent depression.

BACKGROUND: Children referred to child welfare (CW) due to suspected maltreatment are vulnerable and need many services, particularly minority children. OBJECTIVE: To assess whether service use has improved over the past decade and whether racial-ethnic disparities in service use have decreased. METHODS: We used two national data sets (the National Survey of Child and Adolescent Well-Being I and II) collected a decade apart to assess changes over time in health, education, mental health (MH), dental services and overall service use. RESULTS: In NSCAW II, more children were young, had lower child behavior checklist (CBCL) scores, and were Hispanic. We found significant increases in dental services, a decrease in special education services and a decrease in MH services on the bivariate level (all p<.01). A large proportion of the change in MH services occurred in school settings, but the pattern continued when examining only those services delivered outside of school. The greatest decrease occurred for children with CBCL scores <64. However, in multivariate analyses, older children, white non-Hispanic children and children placed out of the home were significantly more likely to receive MH services. Rates of MH services controlling for CBCL scores showed no improvement over the decade, nor was there a decrease in racial and ethnic disparities CONCLUSION: These data show no change in MH services over time for children referred for CW evaluation, but improvement in dental services. Racial and ethnic disparities persist. MH services decrease occurred predominantly among children whose MH symptoms are below the clinical range.

Impulsivity trait was characterized in 3-5 months old BACHD rats, a transgenic model of Huntington disease, using (1) the delay discounting task to assess cognitive/choice impulsivity, and (2) the Differential Reinforcement of Low Rate of Responding task to evaluate motor/action impulsivity. Transgenic animals showed a high level of choice impulsivity and, to a lesser extent, action impulsivity. Our results provide the first evidence that the transgenic BACHD rat (TG5 line) displays impulsivity disorder as early as 3 months old, as described in early symptomatic HD patients, thus adding to the face validity of the rat model.

We analyzed the temporal pattern of conditioned suppression of lever-pressing for food in rats conditioned with tone-shock pairings using either a 10 or 15s conditioned stimulus (CS)-unconditioned stimulus (US) interval with a CS duration that was three times the CS-US interval. The analysis of average suppression and of individual trials was performed during Probe CS-alone trials and when a short gap was inserted during the CS. The pattern of suppression followed the classical temporal rules: (1) scalar property, (2) a shift in peak suppression due to a gap, compatible with a Stop rule, (3) a three-state pattern of lever-pressing in individual trials, with abrupt start and stop of suppression. The peak of the average suppression curve, but not the middle time, was anticipatory to the programmed US time. The pattern of lever-pressing in individual trials unraveled two types of start of suppression behavior: a clock-based biphasic responding, with a burst of lever-pressing before suppression, and a non-clock based monophasic reduction of lever-pressing close to the CS onset. The non-clock based type of behavior may be responsible for the anticipatory peak time, and the biphasic pattern of lever-pressing may reflect the decision stage described in clock models.

OBJECTIVE: Maternal depression affects 10% to 40% of mothers with young children and has negative consequences for children's health and development. The American Academy of Pediatrics (AAP) recommends that pediatricians identify women with maternal depression. The authors examined trends in inquiring about (asking informal questions) or screening for (using a standardized instrument) maternal depression by pediatricians in 2004 and 2013 and identified correlates of usually inquiring/screening to identify maternal depression. METHODS: Data were ascertained from 778 nontrainee pediatricians exclusively practicing general pediatrics who completed the 2004 (n = 457) and 2013 (n = 321) AAP Periodic Surveys. Pediatricians answered questions about physician and practice characteristics, training, attitudes, and inquiring/screening to identify maternal depression. Sample weights were used to reduce nonresponse bias. Weighted descriptive and logistic regression analyses were conducted. RESULTS: The prevalence of usually inquiring/screening to identify maternal depression increased from 33% to 44% (p < .01). In both years, pediatricians who usually inquired about child/adolescent depression had increased odds of usually inquiring/screening to identify maternal depression. Patient race/ethnicity and training in adult Diagnostic and Statistical Manual of Mental Disorders (DSM) diagnostic criteria for depression were associated with inquiring/screening in 2004, and believing that family screening is within the scope of the pediatrician was associated with inquiring/screening in 2013. CONCLUSION: Although inquiring/screening about maternal depression has increased since 2004, less than half of pediatricians usually screen or inquire about maternal depression, representing a missed opportunity to identify depression and manage or refer women for treatment. Further training on the importance of mental and family health to children's health may increase identification of maternal depression in pediatric primary care.
