Some psychometric properties of Adolescent Stress Questionnaire, Lithuanian version

Problema. Nors per pastaruosius keturis dešimtmečius daugėja tyrimų apie paauglių patiriamą stresą, Lietuvoje paauglių patiriamo streso tema yra dar mažai tyrinėta. Trūksta standartizuotų paauglių patiriamo streso vertinimo metodikų. Tyrimo tikslas – įvertinti „Paauglio streso klausimyno“ lietuviškosios versijos kai kuriuos psichometrinius rodiklius (patikimumą ir validumą). Metodai. Tyrime dalyvavo 286 15–17 metų paaugliai. Paauglių patiriamam stresui tirti naudotas „Paauglio streso klausimynas“ („Adolescent Stress Questionnaire“) (Byrne et al., 2007). Jo patikimumas buvo tikrinamas taikant vidinio suderinamumo metodą, pakartotinį matavimą, o konstrukto validumas – taikant tiriančiąją faktorinę analizę. Rezultatai. Tyrimo metu buvo išskirta 11 faktorių, kurie savo turiniu panašūs į originalią australų klausimyno versijos faktorių struktūrą. Tyrimo rezultatai patvirtino vidutinį vidinį ir ganėtinai aukštą išorinį klausimyno patikimumą. Konstrukto validumo įrodymus pateikė tiriančioji faktorinė analizė. Atsižvelgiant į gautus rezultatus, reikėtų atlikti išsamesnius tyrimus dėl klausimyno validumo ir patikimumo patikrinimo.Background. Adolescence is very often named as period when physical, mental, emotional, cognitive and social changes happen, and these changes cause inner conflicts and stress. Considering fact that there was an obvious lack of adolescent stress evaluation methods in Lithuania, it was decided to conduct a research. Aim of this research was to evaluate some psychometric properties (i.e. reliability and validity) of Adolescent Stress Questionnaire, Lithuanian Version. Methodology. Adolescent Stress Questionnaire (Byrne et al., 2007) was used for the research. The questionnaire is made of 58 statements that describe various stressful situations. Participants were asked to evaluate as precise as possible, how strong was the stress they have suffered over the past year due to the mentioned issues and situations. The research included 286 15–17-year-old adolescents. 112 adolescents from general sample participated in test-retest research. Results. Results of the research confirmed quite high internal and external reliability of the questionnaire. Factor analysis delivered proofs of content validity. Out of 46 statements of the questionnaire 11 interdependently related factors were excluded that explain 62.57 percent of dispersion. Analysis of test-retest of questionnaire scales revealed sufficient stability of evaluation (p<0.01). Conclusion. Findings showed that Adolescent Stress Questionnaire was characterized by average internal reliability and sufficient structural validity. It is purposeful to proceed evaluation of this questionnaire’s eligibility, by checking its reliability and validity.
