<p><em>Pengembangan e-commerce untuk pemasaran produk UKM (Usaha Kecil Menengah) telah banyak dilakukan di Indonesia. Beberapa e-commerce telah dikembangkan oleh Pemerintah namun masih belum mampu meningkatkan penjualan produk UKM di daerah. E-commerce Produk UKM harus mampu bersaing dengan e-commerce lain yang sudah berhasil di pasaran. Salah satu cara e-commerce produk UKM untuk meningkatkan daya saingnya adalah dengan mengetahui posisinya di lingkungan pasar online Indonesia. Hal tersebut dapat menjadikan e-commerce produk UKM semakin baik dalam menarik minat konsumen. Pengguna e-comerce dewasa ini tidak hanya memilih e-commerce dari fungsinya tetapi juga kualitas afektifnya. Kualitas afektif berarti e-commerce dapat memuaskan pengguna secara emosional. Tujuan dari penelitian ini adalah untuk mengetahui posisi e-commerce produk UKM berdasarkan pendekatan kualitas afektif e-commerce. Multidimensional Scaling (MDS) digunakan untuk memetakan posisi e-commerce produk UKM dalam persaingan e-commerce di Indonesia. Hasil ekstraksi Kansei Words menggunakan Term Frequency Inverse Document Frequency (TF-IDF) dan Principal Component Analysis (PCA) adalah dua kata kansei (canggih dan terjangkau). Kedua kata ini digunakan untuk analisis posisi sebagai dimensi peta perseptual. Berdasarkan peta perseptual, e-commerces produk UKM sudah canggih tetapi tidak cukup terjangkau.</em></p>

Background: The Intermittent Claudication Questionnaire (ICQ) is a short questionnaire for the assessment of health-related quality of life (HRQOL) in patients with intermittent claudication (IC). The objective of this study was to translate the ICQ into German and to investigate the psychometric properties of the German ICQ version in patients with IC. Patients and methods: The original English version was translated using a forward-backward method. The resulting German version was reviewed by the author of the original version and an experienced clinician. Finally, it was tested for clarity with 5 German patients with IC. A sample of 81 patients were administered the German ICQ. The sample consisted of 58.0 % male patients with a median age of 71 years and a median IC duration of 36 months. Test of feasibility included completeness of questionnaires, completion time, and ratings of clarity, length and relevance. Reliability was assessed through a retest in 13 patients at 14 days, and analysis of Cronbach’s alpha for internal consistency. Construct validity was investigated using principal component analysis. Concurrent validity was assessed by correlating the ICQ scores with the Short Form 36 Health Survey (SF-36) as well as clinical measures. Results: The ICQ was completely filled in by 73 subjects (90.1 %) with an average completion time of 6.3 minutes. Cronbach’s alpha coefficient reached 0.75. Intra-class correlation for test-retest reliability was r = 0.88. Principal component analysis resulted in a 3 factor solution. The first factor explained 51.5 of the total variation and all items had loadings of at least 0.65 on it. The ICQ was significantly associated with the SF-36 and treadmill-walking distances whereas no association was found for resting ABPI. Conclusions: The German version of the ICQ demonstrated good feasibility, satisfactory reliability and good validity. Responsiveness should be investigated in further validation studies.
