The purpose was to evaluate the psychometric properties of an 8-item questionnaire instrument to support member checks in positivistic qualitative research. A sample of 1603 junior-level university nursing students (98.2% participation rate) a completed the questionnaire instrument which assessed how closely a written description of the lived experience of in-hospital training applied to their personal experience. The instrument had excellent psychometric properties, including high measurement reliability (α=0.94), strong concurrent validity (72.2%-77.4%), discriminant validity (p < 0.000001), a parametric score distribution with little kurtosis and no skew, and an average score (G score) was centered at midpoint of the scale (midpoint of 4 on a scale from 1 to 7). The experience match was at the level of “matches experience to high degree,” showing the transferability (generalizability) of the findings to the present sample. The instrument can be used to assess the credibility and transferability of findings from qualitative research, assist in finding negative cases, determine the degree of saturation and success of bracketing, and complement the constant comparative method. The instrument is recommended for general use in positivistic qualitative or naturalistic inquiry studies for any type of sample and any type of lived experience. This approach would magnify and empower the reach of the products of qualitative research.
