Which cognitive tests are used to examine the acute effect of physical activity on cognition in healthy adults aged 50 and older? - A systematic review
Using a theory-based approach to evaluate a physical activity promotion intervention for youth with intellectual disabilities
Predicting clusters of physical activity based on individual characteristics: An event-based ecological momentary assessment study
Objective: Planning can help bridge the physical activity intention behaviour gap, but creating plans has proven burdensome for individuals. Personalised plan recommendations can alleviate this burden and improve plan quality. This study aimed to identify clusters of physical activities and predict these clusters based on static and dynamic person variables to identify relevant variables for personalising recommendations. Design: In a 14-day ecol…
A mobile healthy lifestyle intervention to promote mental health in adolescence: A mixed-methods evaluation
ClinicalTrials.gov [NCT04719858], registered on 22/01/2021
Study protocol for an adapted personal project analysis to measure vertical inter-goal relations on physical activity and diet
This study will provide insights into how the emerging adult population relate healthy behaviors, specifically physical activity and a healthy diet, to their personal values. The degree to which individuals are able to pursue a health goal is also influenced by other life goals, and therefore the conflicting and facilitating relations between health goals and other life goals will also be examined. This study contributes to multiple health behavi…
Towards more personalized digital health interventions: A clustering method of action and coping plans to promote physical activity
The digital health intervention MyPlan 2.0 was preregistered as a clinical trial (ID:NCT03274271). Release date: 6-September-2017
Participatory Development and Pilot Testing of an Adolescent Health Promotion Chatbot
Background: The use of chatbots may increase engagement with digital behavior change interventions in youth by providing human-like interaction. Following a Person-Based Approach (PBA), integrating user preferences in digital tool development is crucial for engagement, whereas information on youth preferences for health chatbots is currently limited. Objective: The aim of this study was to gain an in-depth understanding of adolescents' expectatio…
Estimation of Controlled Direct Effects in Longitudinal Mediation Analyses with Latent Variables in Randomized Studies
In a randomized study with longitudinal data on a mediator and outcome, estimating the direct effect of treatment on the outcome at a particular time requires adjusting for confounding of the association between the outcome and all preceding instances of the mediator. When the confounders are themselves affected by treatment, standard regression adjustment is prone to severe bias. In contrast, G-estimation requires less stringent assumptions than…
Acceptability and feasibility of the mHealth intervention ‘MyDayPlan’ to increase physical activity in a general adult population
Based on these findings, adaptations will be made to the 'MyDayPlan' app before evaluating its effectiveness. Furthermore, involving potential end users and evaluating acceptability and feasibility during the development of an e- and mHealth intervention is key. Also, creating interventions with a large ease of use and straightforward layout that provides tailored support during action and coping planning is key
The association of healthy lifestyle behaviors with mental health indicators among adolescents of different family affluence in Belgium
These findings support the value of integrating healthy lifestyle behaviors in interventions for mental health promotion, for both youth of low-medium and high family affluence
The Effect of the eHealth Intervention ‘MyPlan 1.0’ on Physical Activity in Adults Who Visit General Practice: A Quasi-Experimental Trial
Physical inactivity is one of the major risk factors for poor health in the world. Therefore, effective interventions that promote physical activity are needed. Hence, we developed an eHealth intervention for adults, i.e., ‘MyPlan 1.0’, which includes self-regulation techniques for behaviour change. This study examined the effect of ‘MyPlan 1.0’ on physical activity (PA) levels in general practice. 615 adults (≥18 years) were recruited in 19 Flem…
Process Evaluation of an eHealth Intervention Implemented into General Practice: General Practitioners’ and Patients’ Views
(1) Background: It has been shown that online interventions can be enhanced by providing additional support; accordingly, we developed an implementation plan for the use of an eHealth intervention targeting physical activity and healthy nutrition in collaboration with general practitioners (GPs). In this study, GPs and patients evaluated the actual implementation; (2) Methods: Two hundred and thirty two patients completed the feasibility question…
Experiences and Opinions of Adults with Type 2 Diabetes Regarding a Self-Regulation-Based eHealth Intervention Targeting Physical Activity and Sedentary Behaviour
Background: Online interventions targeting a healthy lifestyle in adults with type 2 diabetes are more effective when informed by behaviour change theories. Although these theories provide guidance in developing the content of an intervention, information regarding how to present this content in an engaging way is often lacking. Consequently, incorporating users’ views in the creation of eHealth interventions has become an important target. Metho…
Lying takes time: A meta-analysis on reaction time measures of deception
Lie detection techniques are frequently used, but most of them have been criticized for the lack of empirical support for their predictive validity and presumed underlying mechanisms. This situation has led to increased efforts to unravel the cognitive mechanisms underlying deception and to develop a comprehensive theory of deception. A cognitive approach to deception has reinvigorated interest in reaction time (RT) measures to differentiate lies…
Attentional bias to pain-relevant body locations: New methods, new challenges
Is attentional prioritization on a location where pain is expected modality-specific or multisensory
A review of current evidence for the causal impact of attentional bias on fear and anxiety
Prominent cognitive theories postulate that an attentional bias toward threatening information contributes to the etiology, maintenance, or exacerbation of fear and anxiety. In this review, we investigate to what extent these causal claims are supported by sound empirical evidence. Although differences in attentional bias are associated with differences in fear and anxiety, this association does not emerge consistently. Moreover, there is only li…
Attention modulates sensory suppression during back movements
Conditioned fear modulates visual selection
Eye movements reflect the dynamic interplay between top-down- and bottom-up-driven processes. For example, when we voluntarily move our eyes across the visual field, salient visual stimuli in the environment may capture our attention, our eyes, or modulate the trajectory of an eye movement. Previous research has shown that the behavioral relevance of a salient stimulus modulates these processes. This study investigated whether a stimulus signalin…
Competing for attentional priority: Temporary goals versus threats
Numerous studies have shown that attention is biased toward threatening events. More recent evidence has also found attentional biases for stimuli that are relevant to the current and temporary goals of an individual. We examined whether goal-relevant information still evokes an attentional bias when this information competes with threatening events. In three experiments, participants performed a dot probe task combined with a separate task that …
Signals of threat do not capture, but prioritize, attention: A conditioning approach
Research suggests that threatening information captures attention more rapidly than neutral information. However, in most studies threat stimuli differ perceptually from neutral stimuli and are instrumental to perform the task, leaving the question unanswered whether threat is sufficient to capture attention. In experiment 1, we designed a visual search task with stimuli of equal salience (colored circles) that have the potential to lead to effic…
Mental quality of life in chronic fatigue is associated with an accommodative coping style and neuroticism: A path analysis
Child's and Parents' Catastrophizing about Pain is Associated with Procedural Fear in Children: A Study in Children with Diabetes and Their Mothers
The contribution of the child's and parents' catastrophizing about pain was explored in explaining procedural pain and fear in children. Procedural fear and pain were investigated in 44 children with Type I diabetes undergoing a finger prick. The relationships between parents' catastrophizing and parents' own fear and estimates of their child's pain were also investigated. The children and their mothers completed questionnaires prior to a routine…
Evaluative conditioning in humans: A meta-analysis
This article presents a meta-analysis of research on evaluative conditioning (EC), defined as a change in the liking of a stimulus (conditioned stimulus; CS) that results from pairing that stimulus with other positive or negative stimuli (unconditioned stimulus; US). Across a total of 214 studies included in the main sample, the mean EC effect was d = .52, with a 95% confidence interval of .466-.582. As estimated from a random-effects model, abou…
Allocation of spatial attention to emotional stimuli depends upon arousal and not valence
Attentional allocation to emotional stimuli is often proposed to be driven by valence and in particular by negativity. However, many negative stimuli are also arousing leaving the question whether valence or arousal accounts for this effect. The authors examined whether the valence or the arousal level of emotional stimuli influences the allocation of spatial attention using a modified spatial cueing task. Participants responded to targets that w…

How can we learn to live with pain? A Q-methodological analysis of the diverse understandings of acceptance of chronic pain
Pain demands attention: A cognitive-affective model of the interruptive function of pain
Pain interrupts and demands attention. The authors review evidence for how and why this interruption of attention is achieved. The interruptive function of pain depends on the relationship between pain-related characteristics (e.g., the threat value of pain) and the characteristics of the environmental demands (e.g., emotional arousal). A model of the interruptive function of pain is developed that holds that pain is selected for action from with…

Selective attention to threat in the dot probe paradigm: Differentiating vigilance and difficulty to disengage
Does Imminent Threat Capture and Hold Attention
According to models of attention and emotion, threat captures and holds attention. In behavioral tasks, robust evidence has been found for attentional holding but not for attentional capture by threat. An important explanation for the absence of attentional capture effects is that the visual stimuli used posed no genuine threat. The present study investigated whether visual cues that signal an aversive white noise can elicit attentional capture a…
Mood-Congruent Attentional Bias in Dysphoria: Maintained Attention to and Impaired Disengagement From Negative Information
Attentional bias to negative information has been proposed to be a cognitive vulnerability factor for the development of depression. In 2 experiments, the authors examined mood-congruent attentional bias in dysphoria. In both experiments, dysphoric and nondysphoric participants performed an attentional task with negative, positive, and neutral word cues preceding a target. Targets appeared either at the same or at the opposite location of the cue…

Attention for emotional faces under restricted awareness revisited: Do emotional faces automatically attract attention
Theoretical models of attention for affective information have assigned a special status to the cognitive processing of emotional facial expressions. One specific claim in this regard is that emotional faces automatically attract visual attention. In three experiments, the authors investigated attentional cueing by angry, happy, and neutral facial expressions that were presented under conditions of limited awareness. In these experiments, facial …

Attentional bias to threat: A perceptual accuracy approach
To investigate attentional bias to threatening information, the authors propose a new version of the spatial cueing paradigm in which the focus is on perceptual accuracy instead of response speed. In two experiments, healthy volunteers made unspeeded discriminations between three visual targets presented left or right. Each target was preceded by a visual cue (colored rectangle) at either the same (valid) or opposite (invalid) location. By means …
