Aim: In this study, we aimed to perform validity and reliability of the Enneagram Types and Subtypes Inventory (ETASI) based on the Enneagram Personality Theory (EPT).

Methods: A self-report scale was developed to evaluate personality types and subtypes based on the EPT. After the pilot application, the final form of ETASI (69 items for types, 30 items for subtypes) and five-factor personality inventory short form (5FPI-SF) were applied as an online form on the Internet. 5FPI-SF was utilized for the concurrent validity. For the construct validity of the subscales, confirmatory factor analyses (CFA) were used, and internal consistency reliabilities were determined by Cronbach Alpha coefficients. Also, test-retest reliabilities were assessed within the four weeks period.

Results: In this study, there were 3531 participants and most of the participants were females (91.3%) and had a higher education level (14.37±4.33 years). For the CFA model, data fit indices of the scales were found as good and acceptable values. Cronbach Alpha coefficients were calculated between 0.665 (type 5) and 0.865 (type 8) for the type scales, and between 0.748 (social) and 0.783 (self-preservation) for the subtype scales. Concurrent validity of the scales (5FPI-SF and ETASI) was found well established. Satisfactory test-retest coefficients of reliability were also confirmed within the range of 0.289 and 0.512 (p<0.05).

Conclusion: Psychometric analyses have shown that ETASI is a valid and reliable self-report personality inventory for determining types and subtypes of EPT.

Amaç: Bu çalışmada Enneagram Kişilik Teorisi (EKT)’ne dayanan Enneagram Tip ve Alt Tip Ölçeği’nin (ETAÖ) geçerlik ve güvenirlik çalışmasını gerçekleştirmeyi amaçladık.

Yöntemler: Kişilik tiplerini ve alt tiplerini değerlendirmek için EKT’ye dayalı bir öz bildirim ölçeği geliştirilmiştir. Pilot uygulama sonrasında, ETAÖ ölçeğinin son hali (tipler için 69 madde, alt tipler için 30 madde) ve beş faktör kişilik ölçeği kısa formu (5FKÖ-KF) internet ortamında çevirimiçi formlar olarak uygulanmıştır. 5FKÖ-KF eşzamanlı geçerlik için kullanılmıştır. Alt ölçeklerin yapı geçerliği için doğrulayıcı faktör analizi (DFA) kullanılmış ve iç tutarlılığın güvenirliği Cronbach Alfa katsayıları ile belirlenmiştir. Ayrıca dört haftalık süre içerisinde test-tekrar test güvenirlikleri değerlendirilmiştir.

Bulgular: Bu çalışmaya 3531 katılımcı dâhil olmuştur ve katılımcıların çoğu kadındır (%91,3) ve yüksek eğitim düzeyine (14,37±4,33 yıl) sahiptir. DFA modeli için ölçeklerin veri uyum indeksleri iyi ve kabul edilebilir değerler olarak bulunmuştur. Cronbach Alfa katsayıları, tip ölçekleri için 0.665 (tip 5) ile 0.865 (tip 8) arasında, alt tip ölçekleri için 0.748 (sosyal) ile 0.783 (kendini koruma) arasında hesaplanmıştır. Ölçeklerin (5FKÖ-KF ve ETAÖ) eşzamanlı geçerliliği iyi olarak belirlenmiştir. Tatmin edici test-tekrar test güvenirlik katsayıları da 0,289 ile 0,512 (p<0.05) aralığında doğrulanmıştır.

Sonuç: Psikometrik analizler, ETAÖ’nün EKT’nin tiplerini ve alt tiplerini belirlemek için geçerli ve güvenilir bir öz bildirim kişilik ölçeği olduğunu göstermiştir.
