Development of computer adaptive tests to assess the psychological status of individuals with an eating disorder or type 2 diabetes
BACKGROUND: Individuals with type 2 diabetes and eating disorders must change their eating behaviors, which are often influenced by psychological factors like depression and anxiety. To efficiently assess daily psychological status, the present study aimed to develop computerized adaptive tests (CAT) based on item response theory (IRT). METHODS: Individuals with depression, anxiety disorders, eating disorders, type 2 diabetes, and healthy persons…
Psychological Field Versus Physiological Field
Welcome to the fifth issue of IEEE Transactions on Computational Social Systems (TCSS) in 2022. After the usual introduction of our 24 regular articles, we would like to discuss the topic of “Psychological Field Versus Physiological Field: From Qualitative Analysis to Quantitative Modelling of the Mental Status.”
Altered distribution of resting periods of daily locomotor activity in patients with delayed sleep phase disorder
Delayed sleep phase disorder (DSPD) and mood disorders have a close relationship. However, the shared mechanisms by DSPD and mood disorders have not been well-elucidated. We previously found that micro-fluctuations in human behaviors are organized by robust statistical laws (behavioral organization), where the cumulative distributions of resting and active period durations take a power-law distribution form and a stretched exponential functional …
Association of Locomotor Activity During Sleep Deprivation Treatment With Response
Disrupted circadian rhythms and sleep patterns are frequently observed features of psychiatric disorders, and especially mood disorders. Sleep deprivation treatment (SD) exerts rapid but transient antidepressant effects in depressed patients and has gained recognition as a model to study quick-acting antidepressant effects. It is of interest how locomotor activity patterns during SD might be associated with and potentially predict treatment respo…
Preceding psychological factors and calorie intake in patients with type 2 diabetes
BACKGROUND: Psychological factors have been reported to have influence on the eating habits of patients with diabetes. However, previous studies have used questionnaires to investigate the association, and thus include recall bias. To overcome this disadvantage, ecological momentary assessment (EMA) can be used to record subjective symptoms and behavior in subjects' daily lives. Therefore, the aim of the present study was to investigate the influ…
Acoustic Hyper-Reactivity and Negatively Skewed Locomotor Activity in Children With Autism Spectrum Disorders
Investigation of objective and quantitative behavioral phenotypes along with neurobiological endophenotypes might lead to increased knowledge of the mechanisms that underlie autism spectrum disorders (ASD). Here, we investigated the association between locomotor dynamics and characteristics of the acoustic startle response (ASR) and its modulation in ASD ( n = 14) and typically developing (TD, n = 13) children. The ASR was recorded in response to…
Development of an ecological momentary assessment scale for appetite
BACKGROUND: An understanding of eating behaviors is an important element of health education and treatment in clinical populations. To understand the biopsychosocial profile of eating behaviors in an ecologically valid way, ecological momentary assessment (EMA) is appropriate because its use is able to overcome the recall bias in patient-reported outcomes (PROs). As appetite is a key PRO associated with eating behaviors, this study was done to de…
Diurnal variation of tension-type headache intensity and exacerbation
BACKGROUNDS: Tension-type headache is a common psychosomatic disease. However, diurnal variation of headache is yet to be clarified, perhaps due to the lack of an appropriate method to investigate it. Like other painful diseases, it would be helpful to know if there is diurnal variation in tension-type headaches, both for managing headaches and understanding their pathophysiology. The aim of this study was to determine if there is diurnal variati…
Does sleep aggravate tension-type headache
BACKGROUND: Both insufficient sleep and oversleeping have been reported as precipitating and aggravating factors of tension-type headache (TTH). However, previous studies relied on recalled self-reports, and the relationship has not been confirmed prospectively and objectively in a daily life situation. Recently, ecological momentary assessment (EMA) using electronic diaries, i.e., computerized EMA, is used to record subjective symptoms with the …
Panic disorder and locomotor activity
BACKGROUND: Panic disorder is one of the anxiety disorders, and anxiety is associated with some locomotor activity changes such as "restlessness". However, there have been few studies on locomotor activity in panic disorder using actigraphy, although many studies on other psychiatric disorders have been reported using actigraphy. Therefore, the aim of the present study was to investigate the relationship between panic disorder and locomotor activ…
Application of ecological momentary assessment in stress-related diseases
Many physical diseases have been reported to be associated with psychosocial factors. In these diseases, assessment relies mainly on subjective symptoms in natural settings. Therefore, it is important to assess symptoms and/or relationships between psychosocial factors and symptoms in natural settings. Symptoms are usually assessed by self-report when patients visit their doctors. However, self-report by recall has an intrinsic problem; "recall b…
Heart Rate and Blood Pressure Variability and Baroreflex Sensitivity in Patients With Anorexia Nervosa
OBJECTIVE: Anorexia nervosa (AN) is considered to have a significant risk for sudden death because of cardiac complications, and abnormalities of the autonomic nervous system might be a cause of cardiac dysfunction. The aim of this study was to investigate autonomic nervous system function in AN patients by analyzing heart rate variability (HRV), blood pressure variability (BPV), and baroreflex sensitivity (BRS). METHODS: The subjects were 32 AN …

Symptom Profile of Multiple Chemical Sensitivity in Actual Life
Objective: This study was conducted to confirm the definition of multiple chemical sensitivity (MCS) in actual life: that multiple symptoms are provoked in multiple organs by exposure to, and ameliorated by avoidance of, multiple chemicals at low levels. We used the Ecological Momentary Assessment to monitor everyday symptoms and the active sampling and passive sampling methods to measure environmental chemical exposure. Methods: Eighteen patient…
Baroreceptor Reflex and Integrative Stress Responses in Chronic Fatigue Syndrome
OBJECTIVE: Altered cardiovascular responses to mental and postural stressors have been reported in chronic fatigue syndrome (CFS). This study examined whether those findings may involve changes in baroreceptor reflex functioning. METHODS: Chronotropic baroreceptor reflex (by sequential analysis) and cardiovascular stress responses were recorded during postural (5-minute of active standing) and cognitive (speech task) stress testing in patients wi…
Genetic variance in age‐related changes in running performance and growth during adolescence
The purpose of this study was to assess an effect of genotype on the patterns of age-related changes in running performance and physical growth during adolescence. The total sample was 14 pairs of male and 25 pairs of female monozygotic (MZ) twins and 19 pairs of male and 15 pairs of female dizygotic (DZ) twins. Performance on the 50-m dash and endurance run (1,500 m for boys and 1,000 m for girls, respectively) and stature and body mass were mea…

Similar age-related changes in running performance and growth in adolescent monozygotic twins
The purpose of this study was to assess the similarities in the pattern of age-related change in the running performance and physical growth in adolescent monozygotic (MZ) twins. The total sample was 70 boys and 100 girls, including 14 pairs of male and 25 pairs of female MZ twins. Performance of the 50 m dash and endurance run (1,500 m for boys and 1,000 m for girls), and stature and body mass were measured longitudinally at yearly intervals fro…
Secular change in running performance of Japanese adolescents
A 5-year longitudinal cohort study of the running development of Japanese adolescents was conducted at a secondary school in Tokyo from 1968 to 1994. The purpose was to investigate changes in the pattern of development over time. The test items were an endurance run (1,500 m for boys and 1,000 m for girls) and a dash (50 m for both sexes). The total number of subjects was 512 boys and 516 girls in the endurance run, and 825 boys and 895 girls in …
