How does early developmental assessment predict academic and attentional-behavioural skills at group and individual levels?

2009

The main aim of the study was to explore the ability of a brief developmental assessment to predict teacher-rated learning and attentional and behavioural skills in the first grade of school at both the group and individual levels. A sample of 394 children (181 males, 213 females) aged 4 years were followed to the age of 6 years, and 283 of the children (145 males, 138 females; mean age 7 y 11 mo) were followed further to the first grade (age 7 y) at school. The children were administered a brief but comprehensive developmental assessment (Lene - a neurodevelopmental screening method) at their local child health-care centres at ages 4 and 6 years. In the first grade, teachers completed a de…

Predictability of oppositional defiant disorder and symptom dimensions in children and adolescents with ADHD combined type.

2010

BackgroundOppositional defiant disorder (ODD) is frequently co-occurring with attention deficit hyperactivity disorder (ADHD) in children and adolescents. Because ODD is a precursor of later conduct disorder (CD) and affective disorders, early diagnostic identification is warranted. Furthermore, the predictability of three recently confirmed ODD dimensions (ODD-irritable, ODD-headstrong and ODD-hurtful) may assist clinical decision making.MethodReceiver-operating characteristic (ROC) analysis was used in order to test the diagnostic accuracy of the Conners' Parent Rating Scale revised (CPRS-R) and the parent version of the Strength and Difficulties Questionnaire (PSDQ) in the prediction of …

Evaluation of the revised sense of coherence scale in a representative German sample.

2018

Background and objectivesTo evaluate the Revised Sense of Coherence (SOC-R) scale in a large representative German sample.DesignA nationwide household survey involving a total of 2510 face-to-face interviews.MethodsIn addition to the SOC-R, childhood trauma and maltreatment (CTM), lifetime traumatic events (Childhood Trauma Questionnaire, CTQ, and the Life Events Checklist for DSM-5, LEC-5), and mental health (Patient Health Questionnaire, PHQ-4) were assessed.ResultsThe final sample consisted of N = 2373 participants (52.3% females; M = 48.24 years). Confirmatory factor analyses confirmed a three-factor structure for the SOC-R ('manageability', 'balance', 'reflection') with acceptable indi…

A new measure of home care patients' dignity at the end of life: The Palliative Patients' Dignity Scale (PPDS).

2015

ABSTRACTObjective:This study aimed to develop a new and brief instrument to be employed in dignity measurement, one based on the perceptions of patients, relatives, and professionals about dignity.Method:Surveys of patients receiving palliative care, family caregivers, and palliative care professionals were first carried out (sample 1). In the second step, palliative care patients were surveyed with a pilot questionnaire (sample 2). Finally, a survey design was used to assess patients admitted into a home care unit (sample 3). Sample 1 included 78 subjects, including patients, family caregivers, and professionals. Some 20 additional palliative patients participated in sample 2. Finally, 70 …

Memorable Experiences with Sad Music : Reasons, Reactions and Mechanisms of Three Types of Experiences

2016

Reactions to memorable experiences of sad music were studied by means of a survey administered to a convenience (N = 1577), representative (N = 445), and quota sample (N = 414). The survey explored the reasons, mechanisms, and emotions of such experiences. Memorable experiences linked with sad music typically occurred in relation to extremely familiar music, caused intense and pleasurable experiences, which were accompanied by physiological reactions and positive mood changes in about a third of the participants. A consistent structure of reasons and emotions for these experiences was identified through exploratory and confirmatory factor analyses across the samples. Three types of sadness …

Smartphone Addiction Inventory (SPAI): Translation, adaptation and validation of the tool in Spanish adult population

2018

The wide functionality and the vast range of attributes offered by smartphones has led to a substantial increase in the average amount of time these devices are used per day. An excessive use of these tools has been shown to result in symptomatology similar to psychological disorders caused by substance addiction. In Spain, smartphone use has risen exponentially but the effects of this increase remain unclear. Therefore, an instrument is required to help determine the extent of smartphone addiction in the Spanish population. The Smartphone Addiction Inventory (SPAI) is a valid and reliable mean to identify and measure smartphone addiction and so, the aim of this research is the translation …

Assessing Reliability, Heritability and General Cognitive Ability in a Battery of Cognitive Tasks for Laboratory Mice

2005

This report includes the first sibling study of mouse behavior, and presents evidence for a heritable general cognitive ability (g) factor influencing cognitive batteries. Data from a population of male and female outbred mice (n = 84), and a replication study of male sibling pairs (n = 167) are reported. Arenas employed were the T-maze, the Morris water maze, the puzzle box, the Hebb-Williams maze, object exploration, a water plus-maze, and a second food-puzzle arena. The results show a factor structure consistent with the presence of g in mice. Employing one score per arena, this factor accounts for 41% of the variance in the first study (or 36% after sex regression) and 23% in the second…

A Pooled Analysis of Reproductive Factors, Exogenous Hormone Use, and Risk of Multiple Myeloma among Women in the International Multiple Myeloma Cons…

2015

Abstract Background: Female sex hormones are known to have immunomodulatory effects. Therefore, reproductive factors and exogenous hormone use could influence the risk of multiple myeloma in women. However, the role of hormonal factors in multiple myeloma etiology remains unclear because previous investigations were underpowered to detect modest associations. Methods: We conducted a pooled analysis of seven case–control studies included in the International Multiple Myeloma Consortium, with individual data on reproductive factors and exogenous hormone use from 1,072 female cases and 3,541 female controls. Study-specific odds ratios and corresponding 95% confidence intervals (CI) were estima…

Prevalence of intimate partner violence against women in Sweden and Spain: A psychometric study of the 'Nordic paradox'.

2019

The high prevalence of intimate partner violence against women (IPVAW) in countries with high levels of gender equality has been defined as the "Nordic paradox". In this study we compared physical and sexual IPVAW prevalence data in two countries exemplifying the Nordic paradox: Sweden (N = 1483) and Spain (N = 1447). Data was drawn from the European Union Agency for Fundamental Rights Survey on violence against women. To ascertain whether differences between these two countries reflect true differences in IPVAW prevalence, and to rule out the possibility of measurement bias, we conducted a set of analyses to ensure measurement equivalence, a precondition for appropriate and valid cross-cul…
