Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Positive cognitions about the self are receiving increasing attention in modern research. The Oxford Positive Self Scale (OxPos) is one of the psychometrically robust assessments of positive self-cognitions. There is a lack of tools assessing positive self-cognitions in Kazakh or Russian. The aim of the study was to adapt and validate the Kazakh and Russian versions of the OxPos.The OxPos was translated into Kazakh and Russian using a back-translation approach. An online survey was conducted using a non-probability sample of 152 participants (54 in Kazakh, 98 in Russian). Construct validity, internal consistency, and convergent validity of the scale were explored. The Rosenberg Self-Esteem Scale (RSES), the Depression, Anxiety and Stress Scale (DASS-21), and the Existence Scale (ESK) were used to evaluate convergent validity.The results confirmed the Kazakh and Russian versions of the OxPos have satisfactory construct validity (adequate model fit for the four-factor model: χ2 = 270.92; CFI = .92; TLI = .91; RMSEA = .04; SRMR = .10 for the Kazakh, χ2 = 282.94; CFI = .94; TLI = .94; RMSEA = .04; SRMR = .08 for the Russian version); excellent internal consistency (ω = .93 for the Kazakh, ω = .94 for the Russian version); excellent convergent validity: positive self-be-liefs correlated positively with self-esteem (r = .77), self-transcendence (r = .34), and correlated negatively with depression (r = –.47).The Oxford Positive Self Scale in Kazakh and Russian is appropriate for use in research and psychological practice as an instrument assessing positive self-beliefs.
