Shorter Version of the Counseling Self-Estimate Inventory (COSE): A Sample from Turkish Counselor Candidates (COSE-TR)

Counseling self-efficacy is defined as a counselor’s beliefs regarding their ability to counsel a client effectively. Larson et al. (1992) developed the Counseling Self-Estimate Inventory (COSE) to determine counselors’ self-efficacy in the dimensions of microskills, counseling process, difficult client behavior, cultural competence, and awareness of values. The COSE has been used widely in the United States as well as being adapted to other cultures. The purpose of the present study was to obtain validity and reliability evidence for the COSE in a Turkish sample towards the creation of a Turkish version (COSE-TR). Analyses regarding internal consistency and construct validity were undertaken via CFA and EFA, and divergent and convergent validity assessments were performed. The devised COSE-TR obtained a Cronbach alpha coefficient of .92. Exploratory factor analysis suggested a four-factor model with 53.82% of the total variance explained, which the CFA also supported. The COSE-TR correlated negatively with trait anxiety as measured on the ‘State-Trait Anxiety Inventory Scale’ (involving only Trait anxiety STAI-T; Spielberger 1983), but positively with generalized self-efficacy as measured via the ‘General Self-Efficacy Scale’ (GSE; Schwarzer and Jerusalem 1995). As for language equivalence, there was no difference between the means of total scores obtained from the original COSE and the created Turkish shorter version. Results revealed that the shortened COSE-TR can be regarded as a valid and reliable instrument for measuring counseling self-efficacy with Turkish counselors. Implications for counseling psychology, counselor education and supervision in developing nations and the transculturality of counseling self-efficacy are discussed.
