Sınır Kişilik Özellikleri Ölçeği Çocuk ve Ergen Formunun Türkçeye uyarlanması: Geçerlilik ve güvenilirlik çalışması

Amaç: Bu araştırma, Sınır Kişilik Özellikleri Çocuk ve Ergen Formunun (SKÖÖ-ÇEF) Türkçe geçerlilik ve güvenilirliğini ortaya koymak amacıyla yapılmıştır. Yöntem: Araştırmanın toplum örneklemi iki farklı okulda öğrenim görmekte olan 12-18 yaşları arasındaki 267 öğrenciden, klinik örneklem kişilik bozukluğu olmayan 15 ve sınır kişilik bozukluğu (SKB) olan 13 hastadan oluşmuştur. Veri toplama aracı olarak Sınır Kişilik Özellikleri Ölçeği-Çocuk ve Ergen Formu, Güçler ve Güçlükler Anketi kullanılmıştır. Klinik örneklemde SCID-II ile yarı-yapılandırılmış görüşmeler yapılmıştır. Ölçeğin güvenilirliğini değerlendirmek için test-tekrar test yöntemi ve Cronbach alfa katsayısı kullanılmıştır. Ölçeğin yapı geçerliliği doğrulayıcı faktör analizi ile değerlendirilmiş, ROC analizi ile ölçeğin kesme puanı test edilmiştir. Bulgular: Çalışmamızda, ölçeğin iç tutarlılığının iyi olduğu gösterilmiştir (Cronbach α=0.83). Madde analizi ile sorunlu olduğu belirlenen beş madde, ek analizlerle değerlendirildikten sonra ikisinin ölçekte kalmasına karar verilmiştir. Doğrulayıcı faktör analizinde ölçeğin özgün faktör yapısı (duygusal düzensizlik, kimlik problemleri, olumsuz ilişkiler, kendine zarar verme) değerlendirildiğinde yeterli uyum iyiliği indeksleri sağlanamamıştır. Bifaktör (bir genel ve dört özgül faktör) model ile yeterli uyum indeksleri elde edilmiş, ölçek maddelerinin daha çok genel faktöre katkı sağladığı görülmüştür. Ölçeğin klinik geçerliliği değerlendirildiğinde, toplum örneklemi ve SKB örnekleminin SKÖÖ-ÇEF toplam puanları arasındaki farkın istatistiksel olarak anlamlı olduğu ve grupları büyük bir etki gücü (d=3.16) ile ayırabildiği görülmüştür. ROC analizi sonucunda kesme puanı 69 olarak belirlenmiştir. Sonuç: Genel olarak sonuçlar SKÖÖ-ÇEF Türkçe sürümünün geçerli ve güvenilir bir araç olduğunu, çocuk ve ergenlerde görülen SKB’de tek boyutlu yapı için kanıtlar ortaya koymuştur.

Borderline Personality Features Scale-Children: adaptation to Turkish, validity and reliability study

Objective: This research aims to investigate validity and reliability of Borderline Personality Features-Children (BPFS-C) in Turkish adolescent sample. Methods: The population sample consists of 267 students between the ages of 12 and 18 who study in two different schools. The clinical sample consists of 15 patients without a personality disorder and 13 patients with borderline personality disorder. Borderline Personality Features-Children, Strengths and Difficulties Questionnaire were used as data collection tools. In the clinical sample, semi-structured interviews were conducted with SCID-II. The test-retest method and Cronbach's alpha coefficient were used to evaluate the reliability of the scale. The construct validity of the scale was evaluated by using confirmatory factor analysis, and the cut-off score of the scale was tested by ROC analysis. Results: The scale's internal reliability was shown to be good (Cronbach α=0.83). In item analysis, five items were problematic; we decided to keep two items after additional analyzes. When the original factor structure of the scale (affect instability, identity problems, negative relationships, self-harm) was evaluated as a result of the confirmatory factor analysis, goodness of fit indices was not acceptable. It was observed that the scale items with sufficient fit indexes in the bifactor (a general factor and four specific factors) model mostly contributed to the general factor. When the scale's clinical validity was evaluated, population sample and patients with Borderline Personality Disorder were distinguished by the total scores of BPFSC with a statistical significance and a large effect size (d=3.16). As a result of the ROC analysis, the cutoff score was determined as 69. Conclusion: Overall, the results revealed that the Turkish version of the BPFS-C is a valid and reliable tool and provided evidence for a unidimensional structure for children and adolescents with borderline personality disorder.
