Background: A mixed approach of including self completion of questionnaires by pencil and paper (PAPI) method and one to one, face to face interview method to gather information on the qualitative measurement of psychological and physical stress intensity and duration in human subjects. The study examines reproducibility of these questionnaires in qualitative research to measure when subject’s behavior, attitude and perception towards their day to day stress conditions. Objective: The Depression Anxiety Stress Scale 21 (DASS-21) and International Physical Activity Questionnaire short form 7 (IPAQ-SF7) were used for this study. A total of 128 subjects were enrolled in the study and their identity was recorded as an alphanumerical value in computer system. They were shown the different signs and symptoms of psychological and physical stress by using an information leaflet. The Informed Consent Form (ICF) was obtained by the researcher. The method of face to face interview was conducted by an interviewer who was professionally a social worker in order to avoid the possible interviewer administration bias. The participant’s responses to the self administrated, open- fixed answered questionnaires were recorded via PAPI. Methodology: The participants were called on to a separate room individually and given the questionnaire. A social worker who was not the part of the study has asked each questions to the subject to avoid administer bias. Each completed questionnaire was put into an envelope were sent to the research team for data processing. Incomplete questionnaires were excluded and those subjects were not asked on second time to attend the study. This was to avid bias in total data processing and interpretation of results. Results: The Readability tests were calculated manually, of which Flesch Reading Ease Score were fairly easy 74.7 for DASS-21(60-70 is largely acceptable) and 70.2 for IPAQ-SF7. The Gunning’s FOG score was 8 for DASS-21 and 7.2 for IPAQ-SF7; remarked as ideal for reading. The internal consistency Cronbach’s alpha (α) obtained for the questionnaires DASS-21 and IPAQ-SF7 were 0.72 and 0.84 respectively, revealed excellent reproducibility of the language versions. The test retest analysis results data showed not a significant difference. Conclusion: The role of ‘Questerview’ (self explanatory, open, closed to fixed answer questionnaires with face to face, one to one asking interview) method in the field of integrated qualitative quantitative clinical studies was one again proved by this study. This will be useful as a non invasive tool to measure participant’s responses to their stress stimuli, where an invasive technique or tool cannot be applied.

Keywords: Questerview, Gunning’s FOG Score, Flesch Reading Ease Score, DASS-21, IPAQ-SF7, Cronbach’s Alpha.
