RESUMEN

Psychiatric symptoms experienced by people with serious mental illness (SMI; schizophrenia, bipolar and other psychotic disorders) may impact suicide safety planning. This study examined safety plan self-knowledge, or an individual's own knowledge and awareness of their safety plan, in a sample of people with SMI. Participants (N = 53) with SMI at elevated risk of suicide completed a 4-session intervention that included safety plans, with one intervention group that included mobile augmentation. Self-knowledge was assessed from previous safety plans at 4-, 12- and 24-weeks. Fewer warning signs generated was correlated with greater psychiatric symptoms (r = - .306, p = .026) and suicidal ideation (r = - .298, p = .030). Fewer coping strategies generated was correlated with greater suicidal ideation (r = .- 323, p = .018). Preliminarily, there was greater self-knowledge of warning signs over time among participants in the mobile intervention. These preliminary findings highlight the relationship of safety plan self-knowledge to symptoms and suggest that mobile augmentation of safety planning may be beneficial. Trial Registration: NCT03198364.

RESUMEN

BACKGROUND: Cognitive tasks delivered during ecological momentary assessment (EMA) may elucidate the short-term dynamics and contextual influences on cognition and judgements of performance. This paper provides initial validation of a smartphone task of facial emotion recognition in serious mental illness. METHODS: A total of 86 participants with psychotic disorders (non-affective and affective psychosis), aged 19-65, were administered in-lab 'gold standard' affect recognition, neurocognition, and symptom assessments. They subsequently completed 10 days of the mobile facial emotion recognition task, assessing both accuracy and self-assessed performance, along with concurrent EMA of psychotic symptoms and mood. Validation focused on task adherence and predictors of adherence, gold standard convergent validity, and symptom and diagnostic group variation. RESULTS: The mean rate of adherence to the task was 79%; no demographic or clinical variables predicted adherence. Convergent validity was observed with in-lab measures of facial emotion recognition, and no practice effects were observed on the mobile facial emotion recognition task. EMA reports of more severe voices, sadness, and paranoia were associated with worse performance, whereas mood more strongly associated with self-assessed performance. CONCLUSION: The mobile facial emotion recognition task was tolerated and demonstrated convergent validity with in-lab measures of the same construct. Social cognitive performance, and biased judgements previously shown to predict function, can be evaluated in real-time in naturalistic environments.

RESUMEN

Sources that contribute to variation in mathematical achievement include both numerical knowledge and general underlying cognitive processing abilities. The current study tested the benefits of tablet-based training games that targeted each of these areas for improving the mathematical knowledge of kindergarten-age children. We hypothesized that playing a number-based game targeting numerical magnitude knowledge would improve children's broader numerical skills. We also hypothesized that the benefits of playing a working memory (WM) game would transfer to children's numerical knowledge given its important underlying role in mathematics achievement. Kindergarteners from diverse backgrounds (n = 148; 52% girls; Mage  = 71.87 months) were randomly assigned to either play a number-based game, a WM game, or a control game on a tablet for 10 sessions. Structural equation modeling was used to model children's learning gains in mathematics and WM across time. Overall, our results suggest that playing the number game improved kindergarten children's numerical knowledge at the latent level, and these improvements remained stable as assessed 1 month later. However, children in the WM group did not improve their numerical knowledge compared to children in the control condition. Playing both the number game and WM game improved children's WM at the latent level. Importantly, the WM group continued to improve their WM for at least a month after playing the games. The results demonstrate that computerized games that target both domain-specific and domain-general skills can benefit a broad range of kindergarten-aged children.

RESUMEN

BACKGROUND: Personality traits may confer vulnerability to psychopathology. However, few studies have examined the association between personality traits and obsessive-compulsive disorder (OCD) course. The present study investigates personality traits, OCD symptom severity, and illness duration as a predictor of OCD remission. METHODS: 166 treatment-seeking adults with OCD, recruited as part of the Brown Longitudinal Obsessive-Compulsive Study, completed the NEO Five-Factor Inventory 3 (NEO-FFI) and were in episode for OCD at time of NEO-FFI completion. Participants were followed for up to 3 years. RESULTS: Results suggest individuals with OCD had a 21 % likelihood of reaching remission over the course of 3 years. Greater OCD symptom severity and longer illness duration were associated with a decreased likelihood of remission. Among the five factors of personality, only low extraversion was associated with a decreased rate of remission. Neuroticism, openness, agreeableness, and conscientiousness were not associated with remission. LIMITATIONS: As this was an observational study, treatment was not controlled precluding examination of treatment on course. Further, data collected on age of onset and symptom severity during follow up were retrospective and therefore are also subject to recall bias. CONCLUSIONS: Our findings provide preliminary support that personality traits are potential factors impacting course and symptom presentation. Future research is necessary to determine the mechanisms in which personality traits may influence the presentation and course of OCD.

RESUMEN

OBJECTIVE: People with serious mental illnesses (SMIs) are at high risk for suicidal ideation and behavior, and yet few suicide prevention interventions have been customized for this group. We describe the outcomes of a pilot trial of Mobile SafeTy And Recovery Therapy (mSTART), a four-session suicide-focused cognitive behavioral intervention for SMI, designed for the transition from acute to outpatient care and augmented with ecological momentary intervention to reinforce intervention content. METHODS: The primary objective of this pilot trial was to evaluate the feasibility, acceptability, and preliminary effectiveness of START. Seventy-eight people with SMI and elevated suicidal ideation were randomized to either: (a) mSTART or (b) START alone (i.e., without mobile augmentation). Participants were evaluated at baseline, 4 weeks (end of in-person sessions), 12 weeks (end of mobile intervention), and 24 weeks. The primary outcome of the study was change in suicidal ideation severity. Secondary outcomes included psychiatric symptoms, coping self-efficacy, and hopelessness. RESULTS: A total of 27% of randomized persons were lost to follow-up after baseline, and engagement with mobile augmentation was variable. There was clinically significant improvement (d = 0.86) in suicidal ideation severity scores sustained over 24 weeks, with similar effects seen for secondary outcomes. Preliminary comparison indicated a medium effect size (d = 0.48) advantage at 24 weeks of mobile augmentation in suicidal ideation severity scores. Treatment credibility and satisfaction scores were high. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: START, regardless of mobile augmentation, was associated with sustained improvement in suicidal ideation severity and secondary outcomes in people with SMI at-risk for suicide in this pilot trial.

RESUMEN

Smartphone-based ecological mobile cognitive tests (EMCTs) can measure cognitive abilities in the real world, complementing traditional neuropsychological assessments. We evaluated the validity of an EMCT of recognition memory designed for use with people with serious mental illness, as well as relevant contextual influences on performance. Participants with schizophrenia (SZ), schizoaffective disorder, and bipolar disorder (BD) completed in-lab assessments of memory (Hopkins Verbal Learning Test, HVLT), other cognitive abilities, functional capacity, and symptoms, followed by 30 days of EMCTs during which they completed our Mobile Variable Difficulty List Memory Test (VLMT) once every other day (3 trials per session). List length on the VLMT altered between 6, 12, and 18 items. On average, participants completed 75.3% of EMCTs. Overall performance on VLMT 12 and 18 items was positively correlated with HVLT (ρ = 0.52, P < .001). People with BD performed better on the VLMT than people with SZ. Intraindividual variability on the VLMT was more specifically associated with HVLT than nonmemory tests and not associated with symptoms. Performance during experienced distraction, low effort, and out of the home location was reduced yet still correlated with the in-lab HVLT. The VLMT converged with in-lab memory assessment, demonstrating variability within person and by different contexts. Ambulatory cognitive testing on participants' personal mobile devices offers more a cost-effective and "ecologically valid" measurement of real-world cognitive performance.

RESUMEN

A growing body of literature demonstrating the malleability of critical higher-order cognitive functions by means of targeted interventions has incited widespread scientific interest, most notably in the form of cognitive training programs. The results are mixed and a point of contention: It has been argued that gains observed in cognitive training are mainly due to placebo effects. To address this, we examined the effect of participant expectations on one type of cognitive training that has been central to the controversy, namely n-back training, by inducing beliefs about expected outcomes. Participants receiving n-back training showed improvements in non-trained n-back performance regardless of expectations, and furthermore, expectations for positive outcomes did not result in any significant gains in an active control group. Thus, there was no detectable expectancy effect in either direction as a function of the cognitive intervention used, suggesting that training-related improvements are unlikely due solely to a placebo effect.
