The Validation and Psychometric Properties of the Gaming Instinctual Motivation Scale.

Being able to quantify gaming motivation in a valid, systematic way has important implications for game designers and gaming user experience researchers. In the present study, we aimed to develop and validate a 30-item Gaming Instinctual Motivation Scale (GIMS) based on Dillon's 6-11 Framework on instinctual gaming motivation and Lazzaro's gaming experience model. To validate the scale, we recruited 194 regular gamers ( = 22.

Maternal melatonin levels and temporal dietary intake: results from MY-CARE cohort study.

Chrononutrition emerges as a novel approach to promote circadian alignment and metabolic health by means of time-of-the-day dietary intake. However, the relationship between maternal circadian rhythm and temporal dietary intake during pregnancy remains understudied. This study aimed to determine the change in melatonin levels in pregnant women across gestation and its association with temporal energy and macronutrient intake.

Chrononutrition is associated with melatonin and cortisol rhythm during pregnancy: Findings from MY-CARE cohort study.

Chrononutrition has been suggested to have an entrainment effect on circadian rhythm which is crucial for metabolic health. Investigating how chrononutrition affects maternal circadian rhythm can shed light on its role during pregnancy. This study aims to determine chrononutrition characteristics of healthy primigravida during pregnancy and its association with melatonin and cortisol rhythm across gestation.

Humility and Competence: Which Attribute Affects Social Relationships at Work?

Between likability and competence, people value likable colleagues (regardless of their competence level) more than competent colleagues. If humility replaces competence, the preference might be different since humility is not always associated with positive outcomes. Humility and competence form four archetypes: humble star, humble fool, competent jerk, and incompetent jerk.

Maternal diet, nutritional status and infant birth weight in Malaysia: a scoping review.

Background: Women's diet and nutritional status during pregnancy are important in influencing birth outcomes. We conducted a systematic scoping review of the best available evidence regarding dietary intake of Malaysian pregnant women, and the associations of maternal diet, anthropometry, and nutrition-related co-morbidities with the infant's birth weight (IBW). The study objectives were to examine: (1) the adequacy of micronutrient intake among pregnant women; and (2) the association of maternal factors (anthropometry, diet, plasma glucose and blood pressure) during pregnancy with IBW.

Mindfulness is Associated with Better Sleep Quality in Young Adults by Reducing Boredom and Bedtime Procrastination.

Objective: Bedtime procrastination is a relatively new topic of research and has been found to compromise sleep. Researchers have studied the predictors, but only a few studies have focused on the ways to reduce bedtime procrastination. Mindfulness, a novel variable in this research area, may shed some light on how to decrease bedtime procrastination.

Psychological state during pregnancy is associated with sleep quality: preliminary findings from MY-CARE cohort study.

Psychological distress during pregnancy may increase the risk of adverse maternal and infant outcomes. Past studies have demonstrated the association between circadian disturbances with psychological health. However, the roles of chronotype and social jetlag on psychological state during pregnancy are yet to be identified.

Circadian rhythm and its association with birth and infant outcomes: research protocol of a prospective cohort study.

Background: Circadian rhythm plays an important role as our internal body's clock that synchronizes behavior and physiology according to the external 24-h light-dark cycle. Past studies have associated disrupted circadian rhythm with higher risk of miscarriages, preterm birth and low birth weights. This paper described the protocol of a prospective cohort study which aims to determine the circadian rhythm in pregnant women, identify its association with maternal factors during pregnancy, gestational weight gain, birth and infant outcomes.

Social support as a comfort or an encouragement: A systematic review on the contrasting effects of social support on cardiovascular reactivity.

Purpose: The stress-buffering hypothesis (Cohen & McKay, 1984, Handbook of psychology and health IV: Social psychological aspects of health (pp. 253-256). Hillsdale, NJ: Lawrence Erlbaum) suggests that one way social support enhances health is by attenuating cardiovascular reactivity (CVR) to stress.

Major flood related strains and pregnancy outcomes.

Objective: To assess the impact of experiencing a major flood during pregnancy on fetal growth and length of gestation, and to consider how flood-related strains might contribute to these effects.

Method: The Red River Pregnancy Project was a prospective study carried out for 3 months immediately after the historic 2009 crest of the Red River in Fargo, North Dakota. Pregnant community residents who were at least 18 years old with a singleton, intrauterine pregnancy participated in the study (N = 169).

Effort and negative affect interact to predict cardiovascular responses to stress.

Objective: Although traditional models posit that negative emotional responses to stress increase cardiovascular reactivity (CVR), laboratory studies have generally not found a strong emotion-CVR association. In this paper, we took a multidimensional approach to examining psychological reactions to stress in three studies.

Methods: In each study we assessed the amount of effort exerted by a participant and the negative affect (NA) felt by the participant with different self-reported measures and an effort behavioural measure.
