Patterns of utilization and a case illustration of an interactive text-based psychotherapy delivery system.

This paper provides data on the experiences of 267 patients, all with self-reported symptoms of depression or anxiety, engaged in an interactive text-based delivery system for psychotherapy. The paper also offers a case study that illustrates the use of this treatment, indicating ways in which such systems can be useful for patients who may not access or benefit from more traditional therapeutic models.

Organizational Learning Strategies and Verbal Memory Deficits in Bipolar Disorder.

BACKGROUND: Verbal memory (VM) impairment is prominent in bipolar disorder (BD) and is linked to functional outcomes. However, the intricacies of VM impairment have not yet been studied in a large sample of BD patients. Moreover, some have proposed VM deficits that may be mediated by organizational strategies, such as semantic or serial clustering. Thus, the exact nature of VM break-down in BD patients is not well understood, limiting remediation efforts. We investigated the intricacies of VM deficits in BD patients versus healthy controls (HCs) and examined whether verbal learning differences were mediated by use of clustering strategies. METHODS: The California Verbal Learning Test (CVLT) was administered to 113 affectively stable BD patients and 106 HCs. We compared diagnostic groups on all CVLT indices and investigated whether group differences in verbal learning were mediated by clustering strategies. RESULTS: Although BD patients showed significantly poorer attention, learning, and memory, these indices were only mildly impaired. However, BD patients evidenced poorer use of effective learning strategies and lower recall consistency, with these indices falling in the moderately impaired range. Moreover, relative reliance on semantic clustering fully mediated the relationship between diagnostic category and verbal learning, while reliance on serial clustering partially mediated this relationship. CONCLUSIONS: VM deficits in affectively stable bipolar patients were widespread but were generally mildly impaired. However, patients displayed inadequate use of organizational strategies with clear separation from HCs on semantic and serial clustering. Remediation efforts may benefit from education about mnemonic devices or "chunking" techniques to attenuate VM deficits in BD. (JINS, 2017, 23, 358-366).

Ecological Assessment of Clinicians' Antipsychotic Prescription Habits in Psychiatric Inpatients: A Novel Web- and Mobile Phone-Based Prototype for a Dynamic Clinical Decision Support System.

BACKGROUND: Electronic prescribing devices with clinical decision support systems (CDSSs) hold the potential to significantly improve pharmacological treatment management. OBJECTIVE: The aim of our study was to develop a novel Web- and mobile phone-based application to provide a dynamic CDSS by monitoring and analyzing practitioners' antipsychotic prescription habits and simultaneously linking these data to inpatients' symptom changes. METHODS: We recruited 353 psychiatric inpatients whose symptom levels and prescribed medications were inputted into the MEmind application. We standardized all medications in the MEmind database using the Anatomical Therapeutic Chemical (ATC) classification system and the defined daily dose (DDD). For each patient, MEmind calculated an average for the daily dose prescribed for antipsychotics (using the N05A ATC code), prescribed daily dose (PDD), and the PDD to DDD ratio. RESULTS: MEmind results found that antipsychotics were used by 61.5% (217/353) of inpatients, with the largest proportion being patients with schizophrenia spectrum disorders (33.4%, 118/353). Of the 217 patients, 137 (63.2%, 137/217) were administered pharmacological monotherapy and 80 (36.8%, 80/217) were administered polytherapy. Antipsychotics were used mostly in schizophrenia spectrum and related psychotic disorders, but they were also prescribed in other nonpsychotic diagnoses. Notably, we observed polypharmacy going against current antipsychotics guidelines. CONCLUSIONS: MEmind data indicated that antipsychotic polypharmacy and off-label use in inpatient units is commonly practiced. MEmind holds the potential to create a dynamic CDSS that provides real-time tracking of prescription practices and symptom change. Such feedback can help practitioners determine a maximally therapeutic drug treatment while avoiding unproductive overprescription and off-label use.

Putting up emotional (Facebook) walls? Attachment status and emerging adults' experiences of social networking sites.

Social networking sites (SNS) like Facebook can increase interpersonal connections but also intensify jealousy, envy, and surveillance behaviors. Attachment styles may help explain differences in experiencing SNS. This study investigated the role of attachment in influencing emerging adults' perceptions and feelings about SNS and their disclosures on SNS. Disorganized and anxious attachment predicted subjects' use of SNS to avoid more personal face-to-face communication, suggesting individuals with these tendencies use SNS to hold relationships at a psychological arm's distance. Anxious attachment also predicted feelings of intimacy when using SNS, perhaps reflecting online needs for comfort from others. A case narrative is presented to show how those with insecure attachment patterns may struggle to avoid interpersonal conflict when being continuously presented with ambiguous social information.

Effects of childhood trauma on adult moral decision-making: Clinical correlates and insights from bipolar disorder.

BACKGROUND: Childhood adversity has been shown to exert profound effects on basic psychological processes well into adulthood. Some of these processes, such as those related to reward and emotion, play critical roles in moral decision-making. As a population with high rates of childhood trauma as well as heterogenous clinical presentation, individuals with bipolar disorder (BD) constitute an enriched group in which to examine the correlates of trauma and other clinical variables with moral cognition. METHODS: 62 euthymic BD patients and 27 controls responded to moral dilemma scenarios and completed the Childhood Trauma Questionnaire. RESULTS: Results revealed a main effect of diagnosis on moral decision-making only when both personal force and an intention were required, indicating a more utilitarian style in BD patients relative to controls. Several interesting patterns also emerged regardless of diagnostic status. Higher ratings of physical neglect were significantly associated with higher ratings of acceptability (a utilitarian tendency) across dilemma types, and a similar pattern was observed at the trend level for experiences of emotional neglect. Significant main effects on moral decision-making were also observed for sex, illness duration, and history of psychotic features in the BD sample. LIMITATIONS: The present study is limited by the self-reported nature of the CTQ and by the small number of trials of moral dilemmas. In addition, practical and clinical implications of the moral dilemmas paradigm are limited due to its abstract nature. CONCLUSIONS: Our results indicate that certain clinical features as well as childhood maltreatment (in particular neglect) may significantly impact moral decision making in adult life. Surprisingly, childhood trauma was associated with a more utilitarian style, which is in the opposite direction from previous effects shown in PTSD. Although speculative, our results suggest that there may be a protective quality associated with utilitarian moral decision-making tendencies.

Dimensional symptom severity and global cognitive function predict subjective quality of life in patients with schizophrenia and healthy adults.

Over the last several decades Quality of Life (QoL) has become increasingly important as an indicator of treatment outcomes; particularly in schizophrenia spectrum disorders because of its close association with functional disability. Numerous studies seeking to elucidate the factors that contribute to QoL in this population have implicated both symptom severity and cognition in determining QoL but the findings have been mixed. The critical factors that appear to impede the lack of consensus in the extant literature examining determinants of QoL include the heterogeneity of the samples and measures examined as well as medication effects across different studies. Thus, the present study sought to address some of these issues by examining the relationship between subjective QoL and both symptom severity and cognitive function in a relatively homogeneous patient sample of patients and a community control sample assessed for dimensional symptom severity. Our results suggest that both global cognitive function and psychiatric symptoms have a significant impact on the subjective QoL of both people with schizophrenia spectrum disorders and psychiatrically healthy adults. Specifically, we found that a global index of cognition as well as self-reported avolitional and depressive symptoms were significantly predictive of QoL in both samples. These findings highlight the importance of addressing cognitive, depressive and avolitional symptoms in the treatment of patients with schizophrenia spectrum disorders and suggest that improvements in these domains may have a meaningful impact on their overall QoL.

Coping strategies and real-world functioning in bipolar disorder.

BACKGROUND: Bipolar disorder (BD) patients encounter significant life adversity, which has contributed to bipolar disorder being a leading cause of disability worldwide. Studies suggest BD patients have more maladaptive coping strategies, some of which can impact their illness course. Yet research on which coping strategies most influence disability is lacking. Such research could inform cognitive-behavioral targets to improve functional outcomes. Thus, we sought to identify relations between coping strategies and real-world function in BD. METHODS: In 92 affectively-stable BD outpatients, we measured coping strategies via the Brief COPE, real-world disability via the World Health Organization Disability Assessment Schedule, current symptoms, illness chronicity, and neurocognitive functioning via the MATRICS. Multiple regression analysis served to identify the neurocognitive domains predictive of disability for entry into subsequent analyses. Multiple regressions assessed how adaptive and maladaptive coping strategies influenced disability. RESULTS: Only one neurocognitive domain, verbal learning, significantly predicted disability and was included in subsequent analyses. Maladaptive coping significantly predicted disability while adaptive coping did not. Behavioral disengagement (giving up) and self-blame were the only remaining predictors of disability, after controlling for age, sex, illness chronicity, current symptoms, and neurocognitive functioning. LIMITATIONS: The study was limited by the use of a self-report disability measure and a brief-form coping scale. CONCLUSIONS: Results suggest that giving up and self-blame are significant predictors of real-world functioning beyond sub-threshold depressive symptoms. Our results in BD expand upon recent schizophrenia studies suggesting that defeatist beliefs negatively influence functional outcomes across the range of major psychiatric disorders.

Social cognition in patients with schizophrenia spectrum and bipolar disorders with and without psychotic features.

BACKGROUND: Social cognition may be critical to the impoverished social functioning seen in serious mental illness. However, although social-cognitive deficits are consistently demonstrated in schizophrenia spectrum disorders (SSD), studies in bipolar disorder (BD) have produced inconsistent results. This inconsistency may relate to symptom profiles of patients studied, particularly the presence or absence of psychotic features. Thus, we examined social cognition in bipolar disorder with psychotic features (BD +) versus without psychotic features (BD -) relative to SSD and controls. METHODS: A sample of 537 SSD patients, 85 BD + patients, 37 BD - patients, and 309 controls were administered the MATRICS Consensus Cognitive Battery, including a social cognition measure, the managing emotions branch of the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT). Analyses of covariance compared MSCEIT performance between diagnostic groups while controlling for race, psychotropic medication status, and neurocognition. RESULTS: SSD but not BD - or BD + patients showed significant MSCEIT deficits relative to controls. CONCLUSIONS: MSCEIT deficits were found in SSD but not BD - or BD +, suggesting that social cognition may represent an underlying difference between SSD and BD. However, variance in MSCEIT performance among BD patients may also suggest latent BD subgroups characterized by social-cognitive deficits. Findings can help inform future investigations into how social cognition and social brain development differ between SSD and BD.

Evidence from structural and diffusion tensor imaging for frontotemporal deficits in psychometric schizotypy.

BACKGROUND: Previous studies of nonclinical samples exhibiting schizotypal traits have provided support for the existence of a continuous distribution of psychotic symptoms in the general population. Few studies, however, have examined the neural correlates of psychometric schizotypy using structural and diffusion tensor imaging (DTI). METHODS: Healthy volunteers between the ages of 18 and 68 were recruited from the community and assessed using the Schizotypal Personality Questionnaire and received structural and DTI exams. Participants with high (N = 67) and low (N = 71) psychometric schizotypy were compared on gray and white matter volume, and cortical thickness in frontal and temporal lobe regions and on fractional anisotropy (FA) within 5 association tracts traversing the frontal and temporal lobes. RESULTS: Higher levels of schizotypy were associated with lower overall volumes of gray matter in both the frontal and temporal lobes and lower gray matter thickness in the temporal lobe. Regionally specific effects were evident in both white matter and gray matter volume of the rostral middle frontal cortex and gray matter volume in the pars orbitalis. Moreover, relative to individuals who scored low, those who scored high in schizotypy had lower FA in the inferior fronto-occipital fasciculus as well as greater asymmetry (right > left) in the uncinate fasciculus. CONCLUSIONS: These findings are broadly consistent with recent data on the neurobiological correlates of psychometric schizotypy as well as findings in schizotypal personality disorder and schizophrenia and suggest that frontotemporal lobe dysfunction may represent a core component of the psychosis phenotype.

POSITIVE AND NEGATIVE SUBCLINICAL SYMPTOMS AND MCCB PERFORMANCE IN NON-PSYCHIATRIC CONTROLS.

Considerable data support the phenomenological and temporal continuity between subclinical psychosis and psychotic disorders. In recent years, neurocognitive deficits have increasingly been recognized as a core feature of psychotic illness but there are few data seeking to elucidate the relationship between subclinical psychosis and neurocogntive deficits in non-clinical samples. The goal of the present study was to examine the relationship between subclinical positive and negative symptoms, as measured by the Community Assessment of Psychic Experiences (CAPE) and performance on the MATRICS Consensus Cognitive Battery (MCCB) in a large (n=303) and demographically diverse non-clinical sample. We found that compared to participants with low levels of subclinical positive symptoms, participants with high levels of subclinical positive symptoms performed significantly better in the domains of working memory (p<.001), verbal learning (p=.007) and visual learning (p=.014). Although comparison of participants with high and low levels of subclinical negative symptoms revealed no differences in MCCB performance, we found that individuals with high levels of subclinical negative symptoms performed significantly better on a measure of estimated IQ (WRAT-3 Reading subtest; p=.02) than those with low levels of subclinical negative symptoms. These results are at odds with prior reports that have generally shown a negative relationship between neurocognitive functioning and severity of subclinical psychotic symptoms, and suggest some potential discontinuities between clinically significant psychotic symptoms and sub-syndromal manifestations of psychosis.

The relation between childhood maltreatment and psychosis in patients with schizophrenia and non-psychiatric controls.

Several lines of evidence suggest that childhood maltreatment is associated with an increased risk for both psychotic disorders and subclinical psychotic-like experiences in the general population. Few studies, however, have sought to examine whether the strength of this relationship is comparable across patient and non-patient groups. The present study sought to compare the strength of the association between childhood maltreatment and self-reported psychotic symptoms in 447 healthy adult volunteers and 184 stable outpatients with schizophrenia or schizoaffective disorder. Strong positive correlations between childhood maltreatment and self-reported symptoms were observed in both groups. Although patients scored significantly higher than controls on both history of childhood maltreatment and self-reported symptoms, the strength of the relationship did not differ between groups. These data provide strong support for etiological continuity between subclinical psychotic symptoms and psychotic disorders.

MATRICS cognitive consensus battery (MCCB) performance in children, adolescents, and young adults.

BACKGROUND: Neurodevelopmental models of schizophrenia suggest that cognitive deficits may be observed during childhood and adolescence, long before the onset of psychotic symptoms. Elucidating the trajectory of normal cognitive development during childhood and adolescence may therefore provide a basis for identifying specific abnormalities related to the development of schizophrenia. The MATRICS Consensus Cognitive Battery (MCCB), which was designed for use in clinical trials targeting cognitive deficits most common in schizophrenia, may provide a mechanism to understand this trajectory. To date, however, there is no performance data for the MCCB in healthy children and adolescents. The present study sought to establish performance data for the MCCB in healthy children, adolescents, and young adults. METHODS: The MCCB was administered to a community sample of 190 healthy subjects between the ages of 8 and 23years. All MCCB domain scores were converted to T-scores using sample means and standard deviations and were compared for significant performance differences between sex and age strata. RESULTS: Analyses revealed age effects following quadratic trends in all MCCB domains, which is consistent with research showing a leveling off of childhood cognitive improvement upon approaching late adolescence. Sex effects after controlling for age only presented for one MCCB domain, with males exhibiting well-known spatial reasoning advantages. CONCLUSIONS: Utilizing this performance data may aid future research seeking to elucidate specific deficits that may be predictive of later development of SZ.
