BEST PRACTICE IN SELECTION INTERVIEWING, 5.4.1 The reliability and fairness of interview data. Assessment methods including personality questionnaires, ability assessments, interviews, or any other assessment method are valid to the extent that the assessment method measures what it was designed to measure. This variation can be because there are differences between interviewers in terms of the questions asked, the data collected and the way that the data is interpreted. Perhaps a third interviewer had another fresh perspective to share, turning it into a real debate. This article focuses on the reliability of interviews. Many are measures designed to improve the reliability of ratings and as we know reliability is a necessary condition for validity. Think of all of the times in an interview that you heard, saw, or interpreted something very differently from your colleague who asked the candidate a similar question. Conducting independent evaluations is thus a more rigorous test of interrater reliability, and addresses the question of … Reliability Interview Questions and Answers will guide you that reliability is the ability of a person or system to perform and maintain its functions in routine circumstances, as well as hostile or unexpected circumstances. Although not widely used, advocates of conversational interviewing argue that it reduces respondent burden and results in higher quality data in situations where the survey information being requested is complex, highly sensitive, or where the topic elicits stress. Introduce yourself and initiate a friendly but professional conversation. Structured interviews are fairly quick to conduct which means that many interviews can take place within a short amount of time. 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. RELIABILITY, FAIRNESS AND VALIDITY OF INTERVIEWS, 5.6. Achieving reliability is challenging because each interview is unique in some way. Reliability in research data refers to the degree to which an assessment consistently measures whatever it is measuring. no two interviewers give similar points to an applicant after the interview. 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. In a very authoritative review of a huge amount of data on selection interviews Conway, Jako and Goodman (1995) found that problems with reliability were commonplace in selection interviews. Organizations Can Benefit from Workplace Age Diversity, Types of commitment and their effects (IO Psychology), How to Create a Feedback-Friendly Organizational Culture. Finally, using a mathematical approach (i.e. Test-retest reliability is best used for things that are stable over time, such as intelligence. For example, semistructured interview reliability data are often simply confined to an agreement with respect to the scoring of a previous or concurrent administration of the interview. An interview is generally a qualitative research technique which involves asking open-ended questions to converse with respondents and collect elicit data about a subject. 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. I have a plan to conduct validation and reliability test for my interview questions regarding the governance in SWM, but i still searching for the best method. Giving them a work sample or test is often superior. Some things should not be measured in an interview. The more error introduced in interviews, the less reliable they are. Like reliability and validity as used in quantitative research are providing springboard to examine what these two terms mean in the qualitative research paradigm, triangulation as used in quantitative research to test the reliability and validity can also illuminate some ways to test or maximize the validity and reliability of a qualitative study. In phase 1 of the study, authors used a Many-Facet Rasch Measurement model to optimize an existing evaluation form for reliability and discrimination. Read more about Reliability... Assessment Validity. Methods. Interviews cover what happened in the past. It’s pretty easy to accidentally allow interview inconsistencies to filter into … This type of reliability assumes that there will be no change in th… Further, lack of validity and biases of interviewers may also trouble interview. A quick task: Read this extract from a selection interview. 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). Reliability and Validity of Interviews Interview validity refers to whether interview questions map to specific competencies listed on the Competency Assessment Worksheet. General inconsistency. Thereby Messick (1989) has What’s All the Training FOR (Frame of Reference)? Interviewer ratings are significantly influenced by both verbal and non-verbal behaviour (Burnett & Motowidlo, 1998). So start learning about the Reliability with the help of this Reliability Interview Questions with Answers guide 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. The researchers found that the more structured the interviews, the more reliable the interview results tended to be. “The second term is reliability, which refers to how consistent the results are over time and on a wide range of people. Few start an interview with a list of the things they want to assess. In-person interviews may be slightly more reliable in assessing a candidate's strengths and weaknesses, despite employment test provider Saterfiel & Associates' webpage titled "Problems Regarding Subjective Interview Techniques." The issue of incremental validity is perhaps less important for selection interviews than it is for other methods of assessment. When interviewers were trained in the interview process and about how to avoid biases reliability also tended to be higher. If a system is reliable, two people assessing the same candidate should get the same results. 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). Then, when you debriefed after the interviews were complete, those differences gave you something really good to discuss, like nuances that the other didn’t pick up on, unique reactions to answers, and so on. There is surprisingly little qualitative research on the links between what candidates actually say and the ratings given by interviewers. Interviews also have several shortcomings, such as lack of reliability, i.e. 3. Parallel forms reliability relates to a measure that is obtained by conducting assessment of the same phenomena with the participation of the same sample group via more than one assessment method.. INTRODUCTION TO INTERVIEWS AS A SELECTION TOOL, 5.4. 2. To ensure maximum validity, there needs to be a one-to-one correspondence between … interviews, you may need to hire skilled interviewers. In terms of impression management, self promotion of past and future behaviour by the interviewee (rather than ingratiation) tend to lead to higher interviewer evaluations (Stevens & Kristoff, 1995). It will not surprise you that as interview structure decreases so reliability also drops. This is not necessarily a deliberate effort to distort the process on the part of the interviewer but rather due to the interactive nature of the interview and the various biases and limits that impact on human decision-making. Be prepared to reschedule the interview … To improve the reliability and discrimination of a pharmacy resident interview evaluation form, and thereby improve the reliability of the interview process. The candidate has been asked to describe a time when they have experienced success in a team work environment and to describe their role in that situation. Reliability is a very important factor in assessment, and is presented as an aspect contributing to validity and not opposed to validity. *International Journal of Selection and Assessment, Interview Reliability: Statistics vs. 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… Messick (1989) transformed the traditional definition of validity - with reliability in opposition - to reliability becoming unified with validity. What attributions are this candidate making (internal or external; stable or unstable; controllable or uncontrollable)? This would be an internal, stable and controllable attribution. The researchers targeted different sources of error, both from the interviewee and interviewers. Research also shows that in terms of adverse impact, interviews give fairer outcomes than many other widely used selection tools including psychometric tests of ability and intelligence (Huffcut & Roth, 1998; Moscoso, 2000). However, the various human biases described in Unit 2 are very relevant in selection interviewing. Reliability or the ability to learn or interpret something unique? There are different aspects of validity and they differ in their focus. 2017 Nov 6;17(1):190. doi: 10.1186/s12909-017-1030-0. Interviewee appearance, accents, physical appearance, and the candidate's and interviewer's experience can all have a significant impact upon the outcome of an interview (Arvey & Campion, 1982). Using historical information to predict the future. Test-retest reliability is measured by administering a test twice at two different points in time. 2. 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. If doing an interview, have specific questions to be answered by the participants. The poor reliability obtained in general clinical practice is due to inconsistent, incomplete, or idiosyncratic interviewing. When Does Job Security Affect Job Performance? I hope anyone can help me. If you are using field notes, be sure to make specific observations. The interviewer in most cases is the subject matter expert who intends to understand respondent opinions in a well-planned and executed series of questions and answers.Interviews are similar to focus groups and surveys … that each interview carries the same validity and reliability. 2. Why Human Resources Matters for Organizational Outcomes, Human Resource Practices Influence How Employees Spend their Time at Work, How Hypocritical Leaders Affect Employee Turnover. Why? They say: "Well, to be honest we were just lucky to come together at the right time. This crossroads can make for great discussion fodder, salty arguments, ideas for new research, or all of the above.

It would be unhappy that interviewers disagreed, because that would jeopardize and threaten the high reliability it would be striving for. This raises the possibility that impression management by the candidate can have a significant impact on interviewer decision-making (Arvey & Campion, 1982). However, there is some debate about whether these effects are biases. Debates lead to unexpected and more in-depth realizations about the candidate that one interviewer could have conjured up alone. Reliability of Multiple Mini-Interviews and traditional interviews within and between institutions: a study of five California medical schools BMC Med Educ . Test-retest reliability is a measure of the consistency of a psychological test or assessment. I think that sometimes I work really well in a team, but it really depends whether the people around me are similar to me and whether or not they like me. 5.1. Many things just can’t be measured accurately during an interview including: many technical skills, team skills, intelligence, attitude and physical skills. Reliability of the interview is argued to often be low, in that interviewers do not follow the same methods of questioning or method of evaluating each individual interview. In particular we are concerned with inter-rater reliability (different interviewers giving similar ratings when observing the same performance) and intra-rater reliability (the same interviewer giving similar ratings when observing the same performance). Reliability is about the consistency of a measure, and validity is about the accuracy of a measure. the 106 articles on the validity or the reliability of interviews located by Wagner reported any quantitative data. 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). Objective. For example, an employee dealing with an irate customer often needs to use impression management: the employee may be feeling angry but needs to maintain calm, friendly and professional behaviour. “The way you determine validity of an assessment system is … I don't think it's really possible to change other people's views or opinions to get them to work better together with each other.". Explain the purpose of your project, the importance of their participation, and the expected duration of the interview. Interviews are time consuming and they are resource intensive. Which is more important? Rigor of qualitative research continues to be challenged even now in the 21st century—from the very idea that qualitative research alone is open to questions, so with the terms rigor and trustworthiness. Reliability in qualitative studies is mostly a matter of “being thorough, careful and honest in carrying out the research” (Robson, 2002: 176). These interviews pose the same set of questions in the same order to all candidates, allowing clearer comparisons between them. Interviewers tended to give higher scores when candidates made internal, stable and controllable attributions about their performance. I have to admit that I am a little torn regarding the desire to strive toward reliability in interviews. Statistical reliability would not have wanted this scenario to take place.
