Validation of the Croatian version of the subjective vitality scale questionnaire (SVS ‒ HR)

Cilj ‒ utvrditi faktorsku strukturu i unutarnju pouzdanost hrvatske verzije Skale subjektivne vitalnosti i time omogućiti širenje istraživanja vitalnosti na hrvatskom jeziku. Metode ‒ Upitnik od 6 pitanja je prevela profesorica engleskog jezika uz konzultacije s dva kineziologa. Na uzorku od 415 sudionika koji su dobrovoljno ispunili hrvatsku verziju Skale subjektivne vitalnosti (engl., Subjective vitality scale ‒ SVS) provedena je konfirmacijska faktorska analiza za utvrđivanje konstruktne valjanosti te je pouzdanost skale utvrđena Cronbach alfa koeficijentom interne konzistentnosti. Rezultati ‒ Originalni model od 6 čestica u podlozi kojih leži jedan faktor pokazao je dobru prikladnost podacima, međutim, utvrđeno je kako čestica 2: „Trenutno se osjećam tako živim da samo želim puknuti.“ ima nisko zasićenje. Sukladno tome, specificiran je drugi model u kojemu je navedena čestica isključena. Model od 5 čestica također je pokazao zadovoljavajuću prikladnost podacima i pouzdanost, te je zadržan. Zaključak ‒ Metrijske karakteristike hrvatske verzije Skale subjektivne vitalnosti (SVS ‒ HR) statistički su zadovoljavajuće te je opravdana buduća primjena navedenog upitnika s ciljem istraživanja u području vitalnosti.Aim ‒ was to determine the factor structure and reliability of the Croatian version of the Subjective vitality scale questionnaire and ensure the spreading research of vitality in the Croatian language. Methods ‒ The 6-item questionnaire was translated by an English teacher in consultation with two kinesiologists. 415 respondents voluntarily completed the Croatian version of the Subjective vitality scale (SVS ‒ CRO). Confirmatory factor analysis was made to confirm construct validity, and the reliability of the scale was determined by the Cronbach alpha coefficient of internal consistency. Results ‒ using factor analysis with inspection of factor loading was noticed that variable 2: “Trenutno se osjećam tako živim da samo želim puknuti.” had lower loading than other variables as well as low correlation with other variables. Considering this, another model was specified in which this particle was excluded. This model also showed a satisfactory fit to the data and reliability and was retained. Conclusion ‒ The metric characteristics of the Croatian version of the Subjective vitality scale (SVS ‒ HR) are statistically satisfactory and the future application of the vitality research in the Croatian language using this questionnaire is justified
