Transferring of the biological nitrification inhibition (BNI) character from Leymus racemosus to wheat

BACKGROUND: For reasons of feasibility, diagnostic telephone interviews are frequently used in research of psychiatric morbidity. However, it is unknown whether diagnostic telephone interviews are as valid as diagnostic face-to-face interviews. RESEARCH QUESTION: Are diagnostic telephone interviews for psychiatric disorders as valid as diagnostic face-to-face interviews? METHOD: A systematic review of original studies in PubMed, PsychINFO and Embase was carried out. We included studies considering (1) the sensitivity and specificity of diagnostic telephone interviews using face-to-face interviews as a golden standard and (2) the agreement between diagnostic telephone and diagnostic face-to-face interviews. Eligible were studies in the general population, in patients at risk for psychiatric disorders and in psychiatric outpatients. We assessed risk of bias with the quality assessment of diagnostic accuracy studies (QUADAS) instrument. RESULTS: We included sixteen studies. The included studies were generally small with thirteen studies reporting about <100 participants. Specificity was generally high in populations with low or intermediate prevalence of psychiatric morbidity. Sensitivity was low in these populations, but slightly higher in samples with more psychiatric disorders. Studies with a higher risk of psychiatric disorders generally reported higher percentages of agreement and higher kappa values. Considering the QUADAS-2 criteria, most studies had a medium or high risk of bias, especially concerning patient selection and unbiased judgement of the test. Of the six studies with a medium or low risk of bias, the three studies assessing current anxiety and depressive disorders yielded kappa values between 0.69 and 0.84, indicating good agreement. DISCUSSION: There is insufficient evidence that diagnostic telephone interviews for the diagnosis of psychiatric disorders are valid, although results for depression and anxiety disorders seem promising

An overview of 19 instruments assessing the doctor-patient relationship: different models or concepts are used.

Item does not contain fulltextOBJECTIVES: The doctor-patient relationship has been linked to patient satisfaction, treatment adherence, and treatment outcome. Many different instruments have been developed to assess this relationship. The large variety makes it difficult to compare results of different studies and choose an instrument for future research. This review aims to provide an overview of the existing instruments assessing the doctor-patient relationship. STUDY DESIGN AND SETTING: We performed a systematic search in PubMed, PsychInfo, EMBASE, and Web of Science for questionnaires measuring the doctor-patient relationship. We appraised each instrument ascertaining the questionnaires focused on the doctor-patient relationship. We compared the content and psychometric characteristics of the instruments. RESULTS: We found 19 instruments assessing the doctor-patient relationship. The instruments assess a variety of dimensions and use diverse conceptual models for the doctor-patient relationship. The instruments found also vary in terms to which they have been psychometrically tested. CONCLUSION: We have provided an overview of 19 instruments assessing the doctor-patient relationship. The selection of an instrument for future research should be based on the model or conceptual basis of the doctor-patient relationship that is most applicable to the study objectives and the health care field in which it will be applied.1 januari 201
