Wearable-Measured Sleep and Resting Heart Rate Variability as an Outcome of and Predictor for Subjective Stress Measures: A Multiple N-of-1 Observational Study

The effects of stress may be alleviated when its impact or a decreased stress-resilience are detected early. This study explores whether wearable-measured sleep and resting HRV in police officers can be predicted by stress-related Ecological Momentary Assessment (EMA) measures in preceding days and predict stress-related EMA outcomes in...

Does Wearable-Measured Heart Rate Variability During Sleep Predict Perceived Morning Mental and Physical Fitness?

The emergence of wearable sensor technology may provide opportunities for automated measurement of psychophysiological markers of mental and physical fitness, which can be used for personalized feedback. This study explores to what extent within-subject changes in resting heart rate variability (HRV) during sleep predict the perceived mental and...

Trends in Daily Heart Rate Variability Fluctuations Are Associated with Longitudinal Changes in Stress and Somatisation in Police Officers

The emergence of wearable sensors that allow for unobtrusive monitoring of physiological and behavioural patterns introduces new opportunities to study the impact of stress in a real-world context. This study explores to what extent within-subject trends in daily Heart Rate Variability (HRV) and daily HRV fluctuations are associated with...

Moderation of the stressor-strain process in interns by heart rate variability measured with a wearable and smartphone app: Within-subject design using continuous monitoring

Background: The emergence of smartphones and wearable sensor technologies enables easy and unobtrusive monitoring of physiological and psychological data related to an individual’s resilience. Heart rate variability (HRV) is a promising biomarker for resilience based on between-subject population studies, but observational studies that apply a...

Investigating resilience patterns based on within-subject changes in sleep and resting heart rate variability: Abstract

Modelling Employee Resilience Using Wearables and Apps: A Conceptual Framework and Research Design

Wearable and App-based Resilience Modelling in Employees (WearMe)

Occupational stress can cause all kinds of health problems. Resilience interventions that help employees deal with and adapt to adverse events can prevent these negative consequences. Due to advances in sensor technology and smartphone applications, relatively unobtrusive self-monitoring of resilience-related outcomes is possible. With models...

Follow-up effects of social comparison information on the quality of life of cancer patients: The moderating role of social comparison orientation

Objective: To examine how social comparison orientation (SCO) moderates the effects of three types of social comparison information on the global quality of life of cancer patients 2 weeks and 3 months later. Design: Cancer patients (n = 226) were provided with social comparison information just prior to undergoing radiation therapy, using...

Neuroticism and responses to social comparison among cancer patients

The present study examined how the effects of three audiotapes containing different types of social comparison information on the mood of cancer patients depended on the level of neuroticism. On the procedural tape, a man and woman discussed the process of radiation therapy, on the emotion tape, they focussed on emotional reactions to their...

Effects of a brief intervention program for patients with cancer and their partners on feelings of inequity, relationship quality and psychological distress

When one member of a couple develops a serious illness, the lives of both partners are likely to be affected. Interventions directed at both partners are generally lacking, however. In the present study, a brief counseling program directed at couples confronted with cancer was evaluated. The intervention focused mainly on the exchange of social...

Translation, validation, and norming of the Dutch language version of the SF-36 Health Survey in community and chronic disease populations

The primary objectives of this research were to translate, validate, and generate normative data on the SF-36 Health Survey for use among Dutch- speaking residents of the Netherlands. Translation of the SF-36 into Dutch followed the stepwise, iterative procedures developed by the IQOLA Project. Following extensive pilot testing, the SF-36 was...
