dc.description.abstractProblem situation: Harter's Self-Perception Profiles have a central position among multi-dimensional measurement instruments and are used frequently in studies of self. Harter's Self-Perception Profile for Adolescents (SPPA), developed for 14-18-year olds, measures self-perception with eight sub-dimensions including scholastic competence, athletic competence, social acceptance, close friendship, romantic appeal, job competence, physical appearance, behavioral conduct, and global self-worth interwoven with other dimensions. Despite its common use, there are some concerns about the scale's questionnaire format as well as its construct validity. Purpose of the study: Taking its common use and criticisms into consideration, the aim of the study is to explore the construct validity and reliability of the more appropriate version of the SPPA for Turkish culture, the original or revised version. Method: After having the instrument translated, the original version was applied to 366 adolescents and the revised version to 395. The exploratory factor analysis was carried out and the results were compared for the two versions. The factor structure of the version, which yielded more satisfactory results, was tested by confirmatory factor analysis with a different sample (N=279). Internal consistency and test-retest reliability studies were conducted on data collected from 110 adolescents. Findings and results: The comparison of the exploratory factor analysis results of the SPPA's original and revised versions showed that the factor Based on the results of the exploratory factor analysis of the revised version, the dimensions that Harter's version took place under the seven factors (romantic appeal, flirt preferences, athletic competence, physical appearance, social acceptance/close friendship, behavioral conduct/scholastic competence and job competence) with 32 items. However, model-data fit indices (chi(2)=665.54 (N=279, sd=386, p=.00), chi(2)/sd=1.69 RMSEA=0.050, RMR=0.069, GFI=0.86, AGFI=0.84 and CFI=0.86) of the CFA indicated that the revised SPPA has a reduced number of 30 items with a six-factor structure (exclude flirt preferences). The Cronbach-alpha coefficient for subscale coefficients ranged between .56 and .78; the r values for test-retest reliability in subscales ranged between .60 and .93. Conclusions and recommendations: The revised SPPA is a valid and reliable measure of the different dimensions of self-concept for Turkish adolescents. However, future studies will better disclose the psychometric properties of the scale within the Turkish culture.en_US
