The objective of this study was to test the psychometric properties of the Polish version of the
(IWPQ).
The study was conducted on 3 independent samples of 1582, 581 and 40 individuals employed as ...manual workers, social service and white collar workers. To test the IWPQ structure an exploratory factor analysis was conducted. Multigroup confirmatory factor analysis and invariance test were carried out among subgroups. The reliability was assessed by means of Cronbach's α coefficient (internal consistent) and test-retest (stability over time) method, with a 4-week follow-up. The construct validity of the IWPQ was tested by means of correlation analysis, using work engagement, positive and negative affect at work, and job burnout as the criterion variables.
The Polish version of the IWPQ displays very good internal consistency, theoretical validity, and test-retest stability. The results of the factor analysis confirmed a 3-factor structure of the questionnaire. Construct invariance across subgroups was confirmed. Task performance was negatively correlated with negative affect at work, job burnout and positively correlated with work engagement and positive affect at work. Contextual performance was negatively related with counterproductive work behaviors, negative affect at work and positively related with work engagement.
The Polish version of the IWPQ - like the original scale - consists of 18 items and has 3 subscales. Despite certain limitations the Polish version of the IWPQ shows good psychometric properties and it can be used to measure individual work performance in Polish conditions.

Job performance is considered the “ultimate dependent variable” in human resource management, turning its assessment into a capital issue. The present study analyzes the functioning of a brief ...18-item self-report scale, the Individual Work Performance Questionnaire (IWPQ), which measures the main dimensions of job performance (task performance, contextual performance, and counterproductive behaviors) in a wide variety of jobs. Participants were 368 employees who voluntarily answered a questionnaire including the IWPQ, other performance scales, and the NEO-FFI. Descriptive statistics, exploratory structural equation modeling, and correlations were performed. Results show that the IWPQ has a tridimensional structure with adequate reliability, exhibits significant associations with other measures of performance, and its association with personality traits is similar in terms of direction and strength of the correlations between other job performance measures and personality. We conclude that the IWPQ is an adequate measure of job performance but with emphasis on behaviors aimed toward organizations.
The aim of this study is to adapt and validate the Individual Work Performance Questionnaire (IWPQ) to a Portuguese version (IWPQ-PT) and to evaluate its psychometric properties in a sample of 423 ...digital sector workers. Two studies were conducted to define the factorial structure. In study 1 (n = 162), the results of an exploratory factor analysis pointed to a three-factor structure (18 items), explaining 55.56% of the variance. In study 2 (n = 261), the results of a confirmatory factor analysis revealed a good model fit (CFI = 0.95; RMSEA = 0.06), also reproducing the structure of the original model. The overall scale and subscales demonstrated good reliability, with Cronbach’s alpha coefficients ranging from 0.72 to 0.88. Correlations between the IWPQ-PT subscales and other instruments revealed that higher task and contextual performance are associated with increased job satisfaction, work engagement, and decreased turnover intention. Conversely, counterproductive work behavior is associated with lower job satisfaction, work engagement, and higher turnover intention. This study underscores the contributions of the IWPQ-PT as a reliable and valid tool for assessing individual work performance in Portuguese organizations and highlights its contributions to the field of employee work performance research as well as human resources practices.
Individual work performance can be defined as individual behaviour capable of generating value and a competitive advantage for the organization. Furthermore, this construct is linked to other ...fundamental variables that constitute worker well-being, such as job satisfaction and engagement. Although important, a complete measure of individual work performance is still lacking in the Italian context. The objective of this work is to validate the Individual Work Performance Questionnaire (IWPQ) within the Italian organisational context. The IWPQ is a multi-dimensional construct consisting of task performance, contextual performance, and counterproductive work behavior. To investigate the psychometric properties of the Italian IWPQ, 1053 participants were enrolled, whose ages ranged between 19 and 69 years. EFA, CFA, and MCFA analyses were performed to test the structural factors of the IWPQ. The results supported the validity of the IWPQ in the Italian context; the final structure consisted of 17 items. Multigroup confirmatory factor analysis showed that the factor solution was invariant across both gender and occupational categories and found evidence of metric, uniqueness, scalar, and structural invariance. Convergent validity was also tested and demonstrated. Adequate studies on the importance of individual performance can be used to better understand and distinguish the different components affecting performance.
Objective: Individual work performance is differently conceptualized and operationalized in different disciplines. The aim of the current review was twofold: (1) identifying conceptual frameworks of ...individual work performance and (2) integrating these to reach a heuristic conceptual framework. Methods: A systematic review was conducted in medical, psychological, and management databases. Studies were selected independently by two researchers and included when they presented a conceptual framework of individual work performance. Results: A total of 17 generic frameworks (applying across occupations) and 18 job-specific frameworks (applying to specific occupations) were identified. Dimensions frequently used to describe individual work performance were task performance, contextual performance, counterproductive work behavior, and adaptive performance. Conclusion: On the basis of the literature, a heuristic conceptual framework of individual work performance was proposed. This framework can serve as a theoretical basis for future research and practice.
There is a need for a short, self-rated, validated and reliable instrument for individual work performance suitable for generic use in the Swedish work and organizational context. The Individual Work ...Performance Questionnaire (IWPQ), comprising originally 47 items, was initially developed in the Netherlands, based on a four-dimensional conceptual framework, in which individual work performance consisted of task performance, contextual performance, adaptive performance, and counterproductive work behavior. During the development process, IWPQ was shortened to 18 items with three scales formally labeled as Task performance, Contextual performance, and Counterproductive work behavior (CWB), capturing three work performance types. The current version of the IWPQ, consisting of 18 items and three scales, was then translated as well as cross-culturally adapted to American-English and Indonesian contexts.
To translate and adapt the current IWPQ version, consisting of 18 items, from the Dutch to the Swedish context, to assess its content validity through cognitive interviews, to apply it to a pilot group to present descriptive statistics, to calculate the questionnaire's internal consistency, as well as to clarify whether the translated items capture three or four performance types.
The Dutch version of the IWPQ, consisting of 18 items, was translated into Swedish. A six-stage translation and adaptation process was used: forward translation, synthesis, back translation, harmonization, cognitive interviews, revision, and sampling and analyses of pilot data for 206 managers (149 women) from five Swedish municipalities.
IWPQ instructions, wording of a few items and one response form were slightly modified. The pilot testing showed Cronbach's alphas similar to the Dutch version of the IWPQ, ranging between 0.73 and 0.82, good mean-inter-item correlations (all above 0.36). In deciding how many factors to retain, we employed both parallel analysis (PA), and Velicer's minimum average partial (MAP) test. The number of factors to retain was, as indicated by PA, four, and by MAP, three or four. Exploratory factor analysis (principal axis factoring) revealed clearly separate factors, corresponding to four, rather than three, performance types. A new factor, roughly representing adaptive performance, comprised in the original, longer version of the IWPQ, emerged.
The Swedish version of the IWPQ was successfully translated and adapted in a pilot group of managers. Before it is used, it should be validated in a larger group of managers and in more heterogeneous groups of both white- and blue-collar workers.
OBJECTIVE:To examine the construct validity of the Individual Work Performance Questionnaire (IWPQ).
METHODS:A total of 1424 Dutch workers from three occupational sectors (blue, pink, and white ...collar) participated in the study. First, IWPQ scores were correlated with related constructs (convergent validity). Second, differences between known groups were tested (discriminative validity).
RESULTS:First, IWPQ scores correlated weakly to moderately with absolute and relative presenteeism, and work engagement. Second, significant differences in IWPQ scores were observed for workers differing in job satisfaction, and workers differing in health.
CONCLUSION:Overall, the results indicate acceptable construct validity of the IWPQ. Researchers are provided with a reliable and valid instrument to measure individual work performance comprehensively and generically, among workers from different occupational sectors, with and without health problems.
Purpose - The purpose of the current study is to develop a generic and short questionnaire to measure work performance at the individual level - the Individual Work Performance Questionnaire (IWPQ). ...The IWPQ was based on a four-dimensional conceptual framework, in which individual work performance consisted of task performance, contextual performance, adaptive performance, and counterproductive work behavior.Design methodology approach - After pilot-testing, the 47-item IWPQ was field-tested amongst a representative sample of 1,181 Dutch blue, pink, and white collar workers. Factor analysis was used to examine whether the four-dimensional conceptual framework could be confirmed. Rasch analysis was used to examine the functioning of the items in more detail. Finally, it was examined whether generic scales could be constructed.Findings - A generic, three-dimensional conceptual framework was identified, in which individual work performance consisted of task performance, contextual performance, and counterproductive work behavior. Generic, short scales could be constructed that fitted the Rasch model.Research limitations implications - A generic, short questionnaire can be used to measure individual work performance across occupational sectors. In future versions of the IWPQ, more difficult items should be added to improve discriminative ability at the high ranges of the scale.Originality value - This study shows that, using Rasch analysis, a generic and short questionnaire can be used to measure individual work performance.
