Statistical reliability would not have wanted this scenario to take place. Explain the purpose of your project, the importance of their participation, and the expected duration of the interview. Reliability is about the consistency of a measure, and validity is about the accuracy of a measure. Interviewer ratings are significantly influenced by both verbal and non-verbal behaviour (Burnett & Motowidlo, 1998). RELIABILITY, FAIRNESS AND VALIDITY OF INTERVIEWS, 5.6. Conducting independent evaluations is thus a more rigorous test of interrater reliability, and addresses the question of … What’s All the Training FOR (Frame of Reference)? Structured interviews are easy to replicate as a fixed set of closed questions are used, which are easy to quantify – this means it is easy to test for reliability. It’s pretty easy to accidentally allow interview inconsistencies to filter into … There are different aspects of validity and they differ in their focus. The latter approach requires each interviewer to make their own judgments about the relative importance of various ratings, thus compromising the standardisation of the interview process. Test-retest reliability is best used for things that are stable over time, such as intelligence. the 106 articles on the validity or the reliability of interviews located by Wagner reported any quantitative data. In addition, panel interviews were more reliable than single-interviewer interviews. Finally, using a mathematical approach (i.e. 5.1. Good eye contact, positive body language and physical attractiveness can lead to higher scores in interviews but generally only for candidates who provide good answers to the questions posed (Rasmussen, 1984; Burnett & Motowidlo, 1998). I have to admit that I am a little torn regarding the desire to strive toward reliability in interviews. Reliability is the consistency of your measurement, or the degree to which an instrument ensures the same way each time it is used under the same condition with the same subjects. From a statistical perspective, that is. “The way you determine validity of an assessment system is … Rigor is simply defined as the quality or state of being very exact, careful, or with strict precision8 or the quality of being thorough and accurate.9 The term qualitative rigor itself is an oxymoron, considering that qualitative research is a journey of explanation and discovery tha… summing the different competency scores) to arrive at an overall score for interviewee performance tended to be more reliable than relying upon the discretion of interviewers to arrive at an overall score. This would be an internal, stable and controllable attribution. Interviews also have several shortcomings, such as lack of reliability, i.e. Introduce yourself and initiate a friendly but professional conversation. In industrial and organizational psychology, this conflict between ideal statistics and personal experience is the crossroads of “where research meets practice.” Sometimes what is helpful isn’t necessarily the ideal scenario or course of action from a statistical perspective. I know from a statistical perspective that interview reliability is important, since the more reliable interviews can be, the more capable they are of statistically predicting the future job performance of candidates (who become hires). that each interview carries the same validity and reliability. Interviewees can introduce error into an interview when they answer similar questions from the same or multiple interviewers differently, while interviewers introduce error when they interpret, evaluate, and rate identical responses differently. Silvester (1997) showed that the attribution theory could be used to help explain the ratings given by interviewers. If interviewees answered the same or similar question in the exact, regurgitatingly same way, and all interviewers heard, interpreted, evaluated, and rated a candidate’s responses in the exact same way, you would have a perfectly reliable interview.
