Positive body language and an ability to manage the impression one gives to others may be viewed as a skill that also has a significant impact on job performance. Reliability or the ability to learn or interpret something unique? 2. 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.. 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). 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. 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.

It’s important to consider reliability and validity when you are creating your research design, planning your methods, and writing up your results, especially in quantitative research. Thereby Messick (1989) has In phase 1 of the study, authors used a Many-Facet Rasch Measurement model to optimize an existing evaluation form for reliability and discrimination. Conducting independent evaluations is thus a more rigorous test of interrater reliability, and addresses the question of … The more error introduced in interviews, the less reliable they are. your personality) rather than the situation, and that you felt that you could do something about it (i.e. 2. RELIABILITY, FAIRNESS AND VALIDITY OF INTERVIEWS, 5.6.

Interviews also have several shortcomings, such as lack of reliability, i.e. 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). 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). 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). 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. The researchers targeted different sources of error, both from the interviewee and interviewers. 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. 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. “The way you determine validity of an assessment system is … 2017 Nov 6;17(1):190. doi: 10.1186/s12909-017-1030-0.

Finally, using a mathematical approach (i.e. 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. 3.
