Predicting the working alliance over the course of long-term psychodynamic psychotherapy with the Rorschach Ego Impairment Index, self-reported defen…

2021

Better therapeutic alliances are known to predict better treatment outcomes, but little knowledge still exists on the patient characteristics that lead to better alliances. In a sample of 128 outpatients assigned to long-term psychodynamic psychotherapy and suffering from mood and/or anxiety disorder, this study evaluated how the alliance, measured using the Working Alliance Inventory (WAI), is predicted by three different measures for assessing psychological resources and vulnerabilities: the Wechsler Adult Intelligence Scale—Revised (WAIS–R), the Defense Style Questionnaire (DSQ), and the Rorschach-based Ego Impairment Index (EII-2). All the three measures showed some ability to predict t…

Item response theory and differential test functioning analysis of the HBSC-Symptom-Checklist across 46 countries

2022

Abstract Background The Symptom Checklist (SCL) developed by the Health Behaviour in School-aged Children (HBSC) study is a non-clinical measure of psychosomatic complaints (e.g., headache and feeling low) that has been used in numerous studies. Several studies have investigated the psychometric characteristics of this scale; however, some psychometric properties remain unclear, among them especially a) dimensionality, b) adequacy of the Graded Response Model (GRM), and c) measurement invariance across countries. Methods Data from 229,906 adolescents aged 11, 13 and 15 from 46 countries that participated in the 2018 HBSC survey were analyzed. Adolescents were selected using representative s…

Cross‐national validation of the Social Media Disorder‐scale : Findings from adolescents from 44 countries

2022

Background and aims There is currently no cross-national validation of a scale that measures problematic social media use (SMU). The present study investigated and compared the psychometric properties of the Social Media Disorder (SMD)-scale among young adolescents from different countries. Design Validation study. Setting and participants Data came from 222,532 adolescents from 44 countries participating in the Health Behaviour in School-aged Children (HBSC) survey (2017/2018). The HBSC survey was conducted in the European region and Canada. Participants were on average 13.5 years old (SD = 1.6) and 51.2% were girls. Measurement Problematic SMU was measured using the 9-item SMD-scale with …

Normal metal - insulator - superconductor thermometers and coolers with titanium-gold bilayer as the normal metal

2018

We have fabricated superconductor - insulator - normal metal - insulator - superconductor (SINIS) tunnel junctions in which Al acts as the superconductor, AlOx is the insulator, and the normal metal consists of a thin Ti layer (5 nm) covered with a thicker Au layer (40 nm). We have characterized the junctions by measuring their current-voltage curves between 60 mK and 750 mK. For comparison, the same measurements have been performed for a SINIS junction pair whose normal metal is Cu. The Ti-Au bilayer decreases the SINIS tunneling resistance by an order of magnitude compared to junctions where Cu is used as normal metal, made with the same oxidation parameters. The Ti-Au devices are much mo…

A New Fitness Test of Estimating VO2max in Well-Trained Rowing Athletes

2021

BackgroundThis study was designed to investigate the validity of maximal oxygen consumption (VO2max) estimation through the Firstbeat fitness test (FFT) method when using submaximal rowing and running programs for well-trained athletes.MethodsWell-trained flatwater rowers (n = 45, 19.8 ± 3.0 years, 184 ± 8.7 cm, 76 ± 12.9 kg, and 58.7 ± 6.0 mL⋅kg–1⋅min–1) and paddlers (n = 45, 19.0 ± 2.5 years, 180 ± 7.7 cm, 74 ± 9.4 kg, and 59.9 ± 4.8 mL⋅kg–1⋅min–1) completed the FFT and maximal graded exercise test (GXT) programs of rowing and running, respectively. The estimated VO2max was calculated using the FFT system, and the measured VO2max was obtained from the GXT programs. Differences between the…

Associations of partnering transition and socioeconomic status with a four-year change in daily steps among Finnish adults

2019

Aim: The aim of this prospective four-year follow-up study was to examine how socioeconomic status (SES) and change in marital status are associated with the change in pedometer-measured physical activity (PA) in adulthood among participants in the ‘Cardiovascular Risk in Young Finns Study’. Methods: Questionnaires were completed and pedometers worn at baseline in 2007 and again at follow-up in 2011 by 1051 Finnish adults (62.3% female, aged 30–45 years in 2007). A latent change score model was used to examine mean change in daily total steps, aerobic steps and non-aerobic steps during weekdays and weekend days between 2007 and 2011. Results: In women re-coupling or finding a new partner wa…

Nuorten fyysistä aktiivisuutta mittaamassa : liikuntaluokkalaisten ja normaaliluokkalaisten vertailu Polar Active® -aktiivisuusmittareilla

2013

Haataja, J. & Sarajärvi, J. 2013. Nuorten fyysistä aktiivisuutta mittaamassa – Liikuntaluokkalaisten ja normaaliluokkalaisten vertailu Polar Active® -aktiivisuusmittareilla. Liikuntapedagogiikan pro gradu -tutkielma, 60s. Tutkimuksen tarkoituksena oli selvittää, minkälaista on yläkoulun liikuntaluokkalaisten fyysinen aktiivisuus. Tarkastelun kohteena oli aktiivisuuden kokonaismäärä ja aktiivisuuden määrä aktiivisuustasoittain. Lisäksi tavoitteena oli verrata fyysisen aktiivisuuden eroja liikuntaluokkien ja normaaliluokkien oppilaiden välillä. Tutkimme myös, liikkuivatko oppilaat liikuntasuosituksiin nähden riittävästi ja oliko fyysisessä aktiivisuudessa eroja sukupuolten sekä luokka-asteide…

Tracking and Changes in Daily Step Counts among Finnish Adults

2021

Purpose This study aimed to investigate the tracking and changes of steps per day in adults and their determinants over 13 yr. Methods A total of 2195 subjects (1236 women) 30-45 yr of age were randomly recruited from the ongoing Cardiovascular Risk in Young Finns Study in 2007 and were followed up in 2020. Steps per day, including both total and aerobic steps per day, were monitored for seven consecutive days with a pedometer in 2007-2008 and 2011-2012 and with an accelerometer in 2018-2020. Tracking was analyzed using Spearman's correlation. Stability and changes of steps per day over time in both low-active and high-active groups (based on median values) were described by percentage agre…

Accelerometer-measured and self-reported physical activity in relation to extraversion and neuroticism: a cross-sectional analysis of two studies

2020

Background Personality reflects relatively stable and pervasive tendencies in feeling, thinking and behaving. While previous studies have found higher extraversion and lower neuroticism to be linked to higher self-reported physical activity levels, larger studies using accelerometer-measured physical activity are lacking. This study investigated the cross-sectional associations of extraversion and neuroticism with both accelerometer-measured and self-reported physical activity and the role of these personality traits in possible discrepancies between these two measures of physical activity among Finnish adults. Methods Two community-dwelling samples were used in this study: a) 47–55-yr-old …
