PURPOSE To assess the factors influencing multiparametric (MP) magnetic resonance (MR) imaging accuracy in estimating prostate cancer histologic volume (Vh). MATERIALS AND METHODS A prospective database of 202 patients who underwent MP MR imaging before radical prostatectomy was retrospectively used. Institutional review board approval and informed consent were obtained. Two independent radio...

BACKGROUND The main aim of this pilot study was to investigate an advanced version of eye movement desensitization and reprocessing (EMDR) for reducing anxiety. METHODS Fifty participants were asked at two times of measurement (T1 and T2 with a rest of 4 weeks) to generate anxiety via the recall of autobiographical memories according to their anxiety. Furthermore, the participants were random...

PURPOSE To compare the responses related to vocal symptoms in two versions of the Vocal Production Condition - Teacher (CPV-T) questionnaire, with responses on a Likert scale and a Visual Analog Scale (VAS), in order to evaluate which is the best measurement method. METHODS A cross-sectional observational study was conducted with teachers with voice disorders during the period from July 2011 ...

BACKGROUND Visual analogue scales (VASs) have been shown to be valid measurement instruments and a better alternative to Likert-type scales in Internet-based research, both empirically and theoretically [1,2]. Upsides include more differentiated responses, better measurement level, and less error. Their feasibility and properties in the context of eHealth, however, have not been examined so far...

building a research questionnaire and using assessment tools play a crucial role in social, management and behavioral sciences. scales and questionnaires are deemed wrongly as the same tools, but in spite of the similarities they are basically and technically different. although making a research scale or questionnaire may seem quite an easy job for some researchers, gathered results by these t...

The purpose of this study is to systematically evaluate the usefulness of Positron emission tomography/Magnetic resonance imaging (PET/MRI) images in a clinical setting by assessing the image quality of Positron emission tomography (PET) images using a three-segment MR attenuation correction (MRAC) versus the standard CT attenuation correction (CTAC). We prospectively studied 48 patients who ha...

BACKGROUND Surgical reconstructive planning following Mohs surgery can be a difficult subject for dermatology residents to master. Prior research demonstrates that active learning is preferred and more effective compared to passive learning models and that dermatology residents desire greater complexity and volume in surgical training. We present a novel, active, problem-based learning tool for...

Likert-type scales are often used in education and psychology. In scales, response options/categories, like items, expected not to direct individuals’ responses. Although the researchers themselves make decision on how arrange categories during scale development, it is possible that different reveal behaviors. literature, has been observed differentiations number of forms studied more, yet ther...
