Behavior Modeling Approach for Forecasting Physical Functioning of People with Multiple Sclerosis

Forecasting physical functioning of people with Multiple Sclerosis (MS) can inform timely clinical interventions and accurate “day planning” to improve their well-being. However, people’s physical functioning often remains unchecked in between infrequent clinical visits, leading to numerous negative healthcare outcomes. Existing Machine Learning (ML) models trained on in-situ data collected outside of clinical settings (e.g., […]

An Interventional Response Phenotyping Study in Chronic Low Back Pain: Protocol for a Mechanistic Randomized Controlled Trial

Evidence-based treatments for chronic low back pain (cLBP) typically work well in only a fraction of patients, and at present there is little guidance regarding what treatment should be used in which patients. Our central hypothesis is that an interventional response phenotyping study can identify individuals with different underlying mechanisms for their pain who thus […]

Mind wandering and sleep in daily life: A combined actigraphy and experience sampling study

Individuals who sleep poorly report spending more time mind wandering during the day. However, past research has relied on self-report measures of sleep or measured mind wandering during laboratory tasks, which prevents generalization to everyday contexts. We used ambulatory assessments to examine the relations between several features of sleep (duration, fragmentation, and disturbances) and mind […]

The temporal relationships between defeat, entrapment and suicidal ideation: ecological momentary assessment study

Background Psychological models of suicidal experiences are largely based on cross-sectional or long-term prospective data with follow-up intervals typically greater than 1 year. Recent time-series analyses suggest that these models may not account for fluctuations in suicidal thinking that occur within a period of hours and/or days. Aims We explored whether previously posited causal relationships […]

The association between sleep disturbance and suicidality in psychiatric inpatients transitioning to the community: protocol for an ecological momentary assessment study

Background: Patients are at high risk of suicidal behavior and death by suicide immediately following discharge from inpatient psychiatric hospitals. Furthermore, there is a high prevalence of sleep problems in inpatient settings, which is associated with worse outcomes following hospitalization. However, it is unknown whether poor sleep is associated with suicidality following initial hospital discharge. […]

Fatigue in patients with hereditary neuropathy with liability to pressure palsies

Objective Hereditary Neuropathy with Liability to Pressure Palsies (HNPP) is caused by a heterozygous deletion of peripheral myelin protein‐22 (PMP22) gene resulting in focal sensorimotor deficits. Our lab has identified a disruption of myelin junctions in excessively permeable myelin that impairs action potential propagation. This mechanism is expected to cause fatigue in patients with HNPP. […]

Can Special Light Glasses Reduce Sleepiness and Improve Sleep of Nightshift Workers? A Placebo-Controlled Explorative Field Study

Nightshift workers go against the natural sleep–wake rhythm. Light can shift the circadian clock but can also induce acute alertness. This placebo-controlled exploratory field study examined the effectiveness of light glasses to improve alertness while reducing the sleep complaints of hospital nurses working nightshifts. In a crossover within-subjects design, 23 nurses participated, using treatment glasses […]

Analysing N-of-1 observational data in health psychology and behavioural medicine: a 10-step SPSS tutorial for beginners

Background: N-of-1 observational studies can be used to describe natural intra-individual changes in health-related behaviours or symptoms over time, to test behavioural theories and to develop highly personalised health interventions. To date, N-of-1 observational methods have been under-used in health psychology and behavioural medicine. One reason for this may be the perceived complexity of statistical […]

Calling out MS fatigue: feasibility and preliminary effects of a pilot randomized telephone-delivered exercise intervention for multiple sclerosis fatigue

Fatigue is a common and debilitating symptom of multiple sclerosis (MS). Exercise therapy is effective in reducing MS-related fatigue; however, its feasibility, acceptability, and effectiveness when delivered over the telephone remain unknown. This randomized study aimed to determine the feasibility and acceptability of a telephone-delivered exercise intervention for MS-related fatigue. In addition, pre-/postchange in fatigue […]

A randomized pragmatic trial of telephone-delivered cognitive behavioral-therapy, modafinil, and combination therapy of both for fatigue in multiple sclerosis

Background Fatigue is one of the most common and disabling chronic symptoms in multiple sclerosis (MS). Optimization of available treatments for MS-related fatigue has been stymied by lack of comparative effectiveness research that focuses on real-world treatment delivery methods and potential modification of treatment effect by other chronic MS symptoms or disability level. This report […]

Combining actigraphy, ecological momentary assessment and neuroimaging to study apathy in patients with schizophrenia

Background Apathy can be defined as a reduction of goal-directed behavior and is a strong predictor for poor functional outcome in schizophrenia. However, no objective measure of apathy has been identified and assessment is limited to retrospective interview-based ratings. Here we aimed to identify more precise objective readouts of apathy for translational research and clinical […]

Influence of Pre-Sleep Positive Affect on Next-Morning Energy

Introduction Objective measures of sleep quality do not fully explain variance in morning reports of feeling rested. What predicts this consequential difference? Sleep duration and quality, as well as chronotype, were documented to impact how energetic people feel in the morning. Very little is known about the impact of positive affect at night on morning […]

Short sleep duration and poor sleep quality predict next-day suicidal ideation: an ecological momentary assessment study

Background. Sleep problems are a modifiable risk factor for suicidal thoughts and behaviors. Yet, sparse research has examined temporal relationships between sleep disturbance, suicidal ideation, and psychological factors implicated in suicide, such as entrapment. This is the first in-the-moment investigation of relationships between suicidal ideation, objective and subjective sleep parameters, and perceptions of entrapment. Methods. […]
