Assessing Statistical Anxiety Among Online and Traditional Students
2019
The purpose of this study was to determine whether scores on the Statistical Anxiety Scale (SAS) manifest in the same way for students in online and traditional statistics courses. Tests of measurement invariance indicated that invariance of the two-factor model of the SAS held at every level. Therefore, we compared the statistical anxiety of online and traditional students. Results indicated that online and traditional statistics students reported comparable levels of anxiety with slightly less anxiety in terms of seeking help for traditional students. We concluded that online instruction is a viable form of statistics education at least for undergraduate students enrolled in the social sc…
The Psychometric properties of the resilience scale (RS-14) in Lithuanian adolescents
2021
In the current study, we provided the evidence of satisfactory validity of the RS-14 scale in the Lithuanian adolescents’ sample (N = 1299; Mage = 14.24; SDage = 1.26), based on its internal structure, and relations to other variables. The results of the study indicated an acceptable model fit for a single-factor structure of the scale with a high internal consistency (McDonald’s omega = 0.89). We also confirmed the scalar measurement invariance across groups of adolescents in terms of their age (i.e., early and middle adolescence) and mental health profile as well as partial scalar gender invariance. Adolescents characterized by high levels of socio-emotional problems reported lower levels…
Utility of Alternative Effect Size Statistics and the Development of a Web-Based Calculator: Shiny-AESC
2018
Alternative displays of effect size statistics can enhance the understandability and impact of validity evidence in a variety of applied settings. Arguably, the proliferation of alternative effect size statistics has been limited due to the lack of user-friendly tools to create them. Common statistical packages do not readily produce these alternative effect sizes and existing tools are outdated and inaccessible. In this paper, I introduce a free-to-use web-based calculator (https://dczhang.shinyapps.io/expectancyApp/) for generating alternative effect size displays from empirical data. This calculator requires no mathematical or programming expertise, and therefore, is ideal for academics …
A New Reliable Performance Analysis Template for Quantifying Action Variables in Elite Men’s Wheelchair Basketball
2019
This study aimed to develop a valid and reliable performance analysis template for quantifying team action variables in elite men’s wheelchair basketball. First action variables and operational definitions were identified by the authors and verified by an expert panel of wheelchair basketball coaching staff in order to establish expert validity. A total of 109 action variable were then placed into 17 agreed Categorical Predictor Variable categories. The action variables were then used to develop a computerized performance analysis template for post-event analysis. Each possession (n = 200) from an international men’s wheelchair basketball game was analyzed by the first author on two occasio…
Psychometric testing of the Norwegian version of the questionnaire Family Satisfaction in the Intensive Care Unit (FS-ICU-24)

Methods: The study design was a cross-sectional survey. After trans…
Methodological Guidelines Designed to Improve the Quality of Research on Cross-Country Skiing
2021
AbstractCross-country (XC) ski races involve a variety of formats, two different techniques and tracks with highly variable topography and environmental conditions. In addition, XC skiing is a major component of both Nordic combined and biathlon competitions. Research in this area, both in the laboratory and field, encounters certain difficulties that may reduce the reliability and validity of the data obtained, as well as complicate comparisons between studies. Here, 13 international experts propose specific guidelines designed to enhance the quality of research and publications on XC skiing, as well as on the biathlon and Nordic combined skiing. We consider biomechanical (kinematic, kinet…
Cultural Adaptation of the Modified Version of the Conflicts Tactics Scale (M-CTS) in Mexican Adolescents
2019
Several scales are used in Dating Violence studies assuming cross-cultural invariance and equivalence of the measures without making the proper validation in the intended populations. This study focuses on the importance of adapting existing dating violence psychological instruments (as the widely recognized Modified Version of the Conflict Tactics Scale, M-CTS) in diverse adolescent populations adjusting to international validation procedures that ensure the cultural fit of the instrument and the measurement invariance of the construct. We sought to adapt the M-CTS in Mexican adolescents (N = 1861; 57.5% woman) following the ITC Guidelines for Translating and Adapting Test. We made an anal…
"En pysty ottamaan valinnaista kieltä vaikka haluaisin" : valinnaiset kielet vähenevät lukiossa
2020
"Liian iso painoarvo annetaan pitkän matikan lukemiselle, ja se on omiaan tappamaan nuorten kieli-innostuksen.” Näin vastasi eräs valinnaisia kieliä opiskeleva lukiolainen keväällä 2020 kysymykseen siitä, millaiset seikat vaikeuttavat valinnaisten kielten opiskelua lukiossa. Valinnaisten kielten opiskelijamäärät lukiossa ovat laskeneet jo usean vuoden ajan, minkä takia moni kielialalla toimiva on huolissaan kielten opiskelun tulevaisuudesta. Opettajien näkemyksiä valinnaisten kielten opiskelijamäärien vähenemisen syille on jo selvitetty, mutta ongelman kokonaisvaltaisen ymmärtämisen kannalta on tärkeä kuulla myös lukiolaisia. Tästä syystä Alina Kiehelä tutki keväällä 2020 toteuttamassaan pr…

Miten lastenhoidon ratkaisuja saa perustella? : vanhempien puhetta 1-2-vuotiaan lapsensa hoitoratkaisuista
2018
Tutkimuksessa selvitettiin, miten vanhemmat jäsentävät ja perustelevat alle kaksivuotiaan lapsensa hoitoratkaisuja. Vanhempien haastatteluista tunnistettiin kolme puhetapaa, jotka tarjoavat toisistaan eroavan näkökulman lapsen hoitoratkaisun perusteluksi. Vanhempien tapa käyttää näitä diskursseja – ”vanhemman hyvinvointi”, ”lapsen paras” ja ”rahapuhe” – osoittaa, kuinka kulttuurisesti ja moraalisesti latautuneesta valinnasta lapsen hoitojärjestelyissä on kyse. Valintaan liittyvät pohdinta ja näkemykset siitä, mitä on hyvä vanhemmuus ja millaista hyvä lapsuus. peerReviewed
