“…The average time of filling out the Korean version of iPCQ was 5 min without missing values, which is similar to that in the previous study, wherein the original version of the iPCQ was developed [ 13 ]. The reliability in all domains of the Korean version of iPCQ was excellent (ICC > 0.9), and these results were similar to those reported in the study by Munk et al [ 25 ].…”

“…Finally, we conducted a correlation analysis for each domain (absenteeism, presenteeism, and unpaid work) between the two instruments. Because all the variables we compared were not normally distributed, we used the Spearman’s rank correlation coefficient ρ (|ρ| < 0.3: low, 0.3 ≤ |ρ| < 0.6: moderate, 0.6 ≤ |ρ|: high) [ 25 ].…”

“…We hypothesized that each domain of productivity loss (absenteeism, presenteeism, and unpaid work) estimated by the iPCQ was negatively correlated with the quality of life. In general, it is known that a patient’s health problem has an effect on the measurement of the health-related productivity loss [ 25 , 26 , 27 , 28 , 29 ]. We classified the correlations into the follow categories: high correlation (r ≥ |0.3|) and low correlation (r < |0.3|) [ 27 , 28 ].…”

This study develops the Korean version of the Institute for Medical Technology Assessment Productivity Cost Questionnaire (iPCQ) through translation/cultural adaptation and evaluation of psychometric properties. We included 110 outpatients visiting a gynecology clinic. We conducted the translation and cross-cultural adaptation of the iPCQ, including forward and back-translation, pilot test with cognitive debriefing, and finalization. We analyzed the feasibility (using average time of filling in the iPCQ and the proportion of missing values), test–retest reliability (using the intra-class correlation coefficient [ICC]), and validity (concurrent validity with the Work Productivity and Activity Impairment [WPAI] and construct validity with the 36-Item Short Form Survey [SF-36], using Spearman’s ρ). The Korean version of iPCQ showed appropriate feasibility (average filling in time was 5.0 min without missing values), and had excellent values in the domains of absenteeism, presenteeism, and unpaid work for test–retest reliability (ICC: 0.92–0.99). For concurrent validity, the Korean version of iPCQ showed moderate–high correlation for absenteeism and presenteeism with the WPAI. All domains of productivity losses measured by the Korean version of iPCQ showed negative correlation with the quality of life estimated by the SF-36. Through this study, we developed a Korean instrument that can measure and value health-related productivity losses including unpaid work as well as absenteeism and presenteeism.

“…In addition to public registry data on sickness absence, production loss will also be measured by the Institute for Medical Technology Assessment Productivity Cost Questionnaire (iPCQ) [26], which assesses absenteeism, presenteeism and unpaid work. The iPCQ has been translated and culturally adapted to Norwegian and found to have good measurement properties when used among Norwegian patients with long-term MSK disorders [27].…”

Background: Little research exists on the effectiveness of motivational interviewing (MI) on return to work (RTW) in workers on long term sick leave. The objectives of this study protocol is to describe a randomized controlled trial (RCT) with the objectives to compare the effectiveness and cost-effectiveness of usual case management alone with usual case management plus MI or usual case management plus stratified vocational advice intervention (SVAI), on RTW among people on sick leave due to musculoskeletal (MSK) disorders.

The aim of this study was to translate the Institute for Medical Technology Assessment Productivity Cost Questionnaire (iPCQ) and the Medical Consumption Questionnaire (iMCQ) from English into Arabic and perform cognitive debriefing in a Saudi Arabian setting. We conducted the translation according to guidelines, including two independent forward translations and a backward translation. Cognitive debriefing was carried out in two stages. First, the pre-final translated versions of the two questionnaires were tested on a group of respondents (n = 5) using face-to-face or telephone interviews. The participants completed a copy of the questionnaires, identified items or questions that were confusing or misunderstood, and then answered a series of open-ended questions about their understanding of each instruction, question and response option. Second, another group of participants (n = 17) completed the questionnaire and circled any word that was confusing or difficult to understand and provided comments on the questionnaires. The Arabic translation and linguistic validation were realized without any major difficulties. The few changes made after cognitive debriefing generally related to changing one word to a more appropriate Arabic word. The final Arabic translation needs to be validated for psychometric properties such as validity and reliability before being recommended for use in future research.
