Psychometric properties of the Turkish adaptation of the social issues advocacy scale-2 short form

BackgroundPrevious literature provides a limited number of measurement instruments for social issues advocacy. The present study focuses on the adaptation of the Social Issues Advocacy Scale-2 Short Form (SIAS-2 SF) into Turkish for counselor and counselor candidates and the evaluation of its psychometric properties.MethodsThe research was performed in four phases. A total of 639 participants were employed, including 173 counselors and 466 counselor candidates (495 female, 144 male). The pilot study included 36 participants, the construct validity and reliability assessment phase involved 422 participants, the test-criterion validity and reliability assessment phase involved 148 participants, and the test, retest reliability phase involved 33 participants. The analysis was performed with JASP and JAMOVI software.ResultsThe results indicated that the Turkish version of the SIAS-2 SF, consisting of 38 items across eight dimensions, demonstrated acceptable model fit indices. Factor loadings ranged from 0.32 to 0.91. The Turkish version of the SIAS-2 SF showed satisfactory internal consistency in the first administration (Phase II: ω = 0.933, α = 0.933) and in the second administration (Phase III: ω = 0.934, α = 0.938), along with adequate test, retest reliability (r = 0.69). Social issues advocacy, social justice, and life satisfaction were found to be moderately and positively correlated.ConclusionThese findings suggest that the SIAS-2 SF is a useful and comprehensive measurement instrument for Turkish counselors and counselor candidates. The SIAS-2 SF can be utilized for pioneering research.
