A Study of Reliability and Validity For the Turkish Version of Dizziness Handicap Inventory

Abstract

Objective: Dizziness is one of the most frequently seen unresolved diseases in primary health care. Regardless of its reason or characteristics; effects of dizziness in patients' daily life are very significant. This study is planned to adapt the Dizziness Handicap Inventory to Turkish and to use it in practice; an inventory which can be used to determine the alterations in the life qualities of the outpatients or inpatients consulted with the dizziness complaint. Method: 178 patients were included in the study, who was admitted to Turgut Ozal University Medical Faculty Otorhinolaryngology and Family Physician polyclinics with dizziness complaint for last 1 month. A semi-structured interview form and Dizziness Disability Inventory were used as data collection means. Results: Dizziness Disability Inventory; consists of 25 clauses which determine the aggravating factors associated with dizziness and shakiness and also the emotional and functional results of vestibular system diseases. The inventory consists of 3 sub-dimensions, intended to determine physical, emotional and functional effects of the vestibular system diseases. All of the sub-dimensions have high internal-confidence and their Cronbach Alfa values are between 0,67 and 0,82. Also the Cronbach Alfa values of the sub-inventory groups were similar with the general inventory. Conclusion: The findings obtained from the study show that this inventory may be used on dizziness patients in Turkey, and it has satisfactory validity and reliability coefficients. It may be concluded that, by using this inventory, dizziness complaint and its effects on life quality can be monitored via more objective criteria. ÖZETAmaç: Birinci basamakta en çok karşımıza çıkan ayrışmamış hastalık durumlarından biri, baş dönmesidir. Sebebi ve karakteristiği her ne olursa olsun baş dönmesinin hastaların günlük yaşamlarına olan etkisi oldukça önemlidir. Bu çalışma; baş dönmesi yakınması ile başvuran, ayaktan ya da yatarak tedavi edilen hastaların yaşam kalitelerindeki değişikliği belirlemede kullanılabilecek Baş Dönmesi Engellilik Envanterinin (Dizziness Handicap Inventory), Türkçeye uyarlanması ve pratikte kullanılması amacıyla planlanmıştır. Yöntem: Çalışmaya Turgut Özal Üniversitesi Tıp Fakültesi Kulak Burun Boğaz ve Aile Hekimliği Polikliniklerine son bir aydır devam eden baş dönmesi yakınması ile başvuran 178 hasta dahil edilmiştir. Veri toplama araçları olarak yarı yapılandırılmış görüşme formu ve Baş dönmesi Engellilik Envanteri kullanılmıştır. Bulgular: Baş Dönmesi Engellilik Envanteri, hastaların baş dönmesi ve denge bozukluğu ile ilgili ağırlaştırıcı faktörlerin yanı sıra vestibüler sistem hastalıklarında duygusal ve fonksiyonel sonuçları belirleyen 25 maddeden oluşmaktadır. Envanter, vestibüler sistem hastalıklarının fiziksel, duygusal ve fonksiyonel etkilerini belirlemeye yönelik üç alt envanter içermektedir. Tüm alt envanterlerin iç güvenirlikleri yüksek ve Cronbach alfa değerleri 0,67 ile 0,82 arasındadır. Envanterin genelinde olduğu gibi alt envanter gruplarından elde ed...

The Relationship of Vestibulo-Ocular Reflex With Self-Reported Dizziness Handicap in Patients With Vestibular Deafferentation

“…Organized form of covert and overt saccades: If there was an overlap and occurred at close milliseconds, those saccades were classified as ''organized''; if not, they were classified as being ''scattered,'' as defined in the literature. 12 The Turkish version of the DHI 14,15 was administered to all patients by the neuro-otologist prior to VHIT. This inventory is used to determine changes in the quality of life of patients with dizziness and comprises 25 statements to be answered as yes, sometimes, or no, scored as 4, 2, and 0, respectively.…”

Long-Term Balance Outcomes in Vestibular Ablative Surgeries

“…DHI is an inventory used to determine the changes in the quality of life in dizzy patients. The Turkish version of the DHI was applied to all patients ( 10 ). The inventory comprises 25 statements that investigate the conditions in daily activities, that are answered with “ yes”, “ sometimes” or “ no” .…”

Psychological profile and personal traits in patients with vestibular dysfunction

“…High scores are considered as those which indicate that the patients' complaints of dizziness severely handicap their QOL. The reliability and validity of the scale in Turkey has been established by Canbal et al 14 .…”
