The “Mainzer EMF-Wachhund”: results from a watchdog project on self-reported health complaints attributed to exposure to electromagnetic fields
2006
The "Mainzer EMF-Wachhund," a watchdog project, offered a system of self-notification of health complaints attributed to exposures to electromagnetic fields (EMFs) to a population of a part of Germany with about 4 million inhabitants. By using a self-administered questionnaire, which was provided online and for download from the Internet, 192 persons reported such health complaints in the period from October 2003 to March 2005. Of these, 56% classified themselves as electromagnetic hypersensitive (EH). Predictors of this self classification were being affected by all kinds of EMF rather than single EMF sources and being female. On average, EH subjects reported a high degree of suffering, 77…
Associations between self-estimated and measured physical fitness among 40-year-old men and women
2005
The aim was to evaluate whether 40-year-old men and women are able to estimate their level of fitness compared with actual measured physical fitness. Twenty-nine men and 35 women first completed a questionnaire at home and then their physical fitness was measured at laboratory. The index of self-estimated physical fitness was calculated by summing up the scores of self-estimated endurance, strength, speed and flexibility. The index of self-estimated endurance was calculated by summing up the scores of self-estimated endurance and those of the self-estimated distance they could run, cycle, ski and walk. The index of measured physical fitness was calculated by summing up the z-scores of a sub…
Self-rated health and mortality: Could clinical and performance-based measures of health and functioning explain the association?
2005
It is well established that self-rated health (SRH) predicts mortality even when other indicators of health status are taken into account. It has been suggested that SRH measures a wide array of mortality-related physiological and pathological characteristics not captured by the covariates included in the analyses. Our aim was to test this hypothesis by examining the predictive value of SRH on mortality controlling for different measurements of body structure, performance-based functioning and diagnosed diseases with a population-based, prospective study over an 18-year follow-up. Subjects consisted of 257 male residents of the city of Jyväskylä, central Finland, aged 51-55 and 71-75 years.…
Self-Rated Health and Associated Factors Among Men of Different Ages
1986
The connections of certain clinico-physiological indicators of health state, chronic diseases, felt symptoms, and psychic well-being with self-rated health were studied among men of different ages as a part of the more extensive research project Jyväskylä Studies on Functional Aging. Study population was selected by using systematic random sampling among men aged 31 to 35, 51 to 55 and 71 to 75 years in the city of Jyväskylä. Log-linear and logit models as well as regression and structural equation models within the framework of LISREL were used as methods of analysis. The associations between general self-rated health and the explanative variables were different in different age groups: In…
Personality Variables as Predictors of Facebook Usage
2014
This study investigates the role of personality factors as predictors of Facebook usage. Data concerning Facebook usage and personality factors from 654 Facebook users were gathered using a web survey. Using path analysis, the results showed Openness was a predictor of Facebook early adoption, Conscientiousness with sparing use, Extraversion with long sessions and abundant friendships, and Neuroticism with high frequency of sessions. The possible role of Agreeableness in predicting low session frequency and friendships needs further validation.
Usability and Trust in E-Banking
2007
This study assessed the role of usability in trust of e-banking services. A questionnaire was administered to 185 Italian undergraduate working students who volunteered for the experiment (M age = 30.5 yr., SD = 3.1). Participants were differentiated on computer ability (Expert, n=104; Nonexpert, n = 81) and e-banking use (User, n = 93; Nonusers, n = 92). Analysis showed that the website usability of e-banking services did not play a very important role for the User group. Instead, institution-based trust, e.g., the trust in the security policy of the Web merchant, customers, and the overall trust of the bank were the crucial factors in the adoption of e-banking. © Psychological Reports 200…
Italian version of the MD Anderson Symptom Inventory-Head and Neck Module: linguistic validation
2015
Background: Head and neck cancer (HNC) patients can experience symptoms due to the tumor itself or to the treatment, with an impact on health-related quality of life (HRQoL). Patient-reported outcome (PRO) measures pertaining to HRQoL are used in medical research and to support clinical decisions. PRO instrument applicability and cultural adaptation must be tested for each population. The aim of this study is to linguistically validate the Italian translation of the M.D. Anderson Symptom Inventory—Head and Neck Module (MDASI-HN). Methods: Following forward and backward translation of the items of the English MDASI-HN into Italian, it was administered along with a cognitive debriefing to HNC…
Psychophysiological and vocal measures in the detection of guilty knowledge.
2004
The Guilty Knowledge Test (GKT) and its variant, the Guilty Actions Test (GAT), are both psychophysiological questioning techniques aiming to detect guilty knowledge of suspects or witnesses in criminal and forensic cases. Using a GAT, this study examined the validity of various physiological and vocal measures for the identification of guilty and innocent participants in a mock crime paradigm. Electrodermal, respiratory, and cardiovascular measures successfully differentiated between the two groups. A logistic regression model based on these variables achieved hit rates of above 90%. In contrast to these results, the vocal measures provided by the computerized voice stress analysis system …
Hypnosis Attitudes: Treatment Effects and Associations With Symptoms in Individuals With Cancer.
2017
Attitudes about hypnosis are associated with hypnotic responsiveness. However, little is known about how hypnosis attitudes change with treatment and if those changes are associated with better outcomes. This study examined whether an intervention based on the Valencia Model of Waking Hypnosis combined with Cognitive-Behavioral Therapy changed attitudes about hypnosis in a sample of patients with a history of cancer. The results indicated that the intervention improved attitudes toward hypnosis, relative to a control intervention, and the improvements remained stable at 3-month follow-up. Analyses also showed that changes in some attitudes were associated with treatment-related improvements…
Fatigue in multiple sclerosis is closely related to sleep disorders: a polysomnographic cross-sectional study.
2011
Background: Sleep disorders can cause tiredness. The relationship between sleep disorders and fatigue in patients with multiple sclerosis (MS) has not yet been investigated systematically. Objective: To investigate the relationship between fatigue and sleep disorders in patients with MS. Methods: Some 66 MS patients 20 to 66 years old were studied by overnight polysomnography. Using a cut-off point of 45 in the Modified Fatigue Impact Scale (MFIS), the entire cohort was stratified into a fatigued MS subgroup ( n = 26) and a non-fatigued MS subgroup ( n = 40). Results: Of the fatigued MS patients, 96% ( n = 25) were suffering from a relevant sleep disorder, along with 60% of the non-fatigue…
