Development and initial validation of a hierarchically structured multidimensional scale of quality of working life

The quality of working life (QWL) has long been a central yet ill-defined concept in organizational psychology, encompassing employee well-being, satisfaction, and the characteristics of the work environment. A recent study published in Frontiers in Psychology aims to bring clarity to this domain by formalizing QWL as a multidimensional construct and developing a robust, stakeholder-grounded instrument for its assessment. The research, conducted by Cristina Jenaro and colleagues, introduces a new scale designed to offer a more comprehensive understanding of what constitutes a high quality of working life, moving beyond simplistic satisfaction-based measures.

Addressing Conceptual Fragmentation in QWL Research

Historically, research on QWL has been hampered by a lack of conceptual integration. Different traditions, particularly in North America and Europe, have emphasized distinct aspects, leading to a proliferation of instruments that capture only partial facets of the construct. This has made it difficult to compare findings across studies and to build a cohesive body of knowledge. The new study addresses this by proposing a hierarchical model of QWL, viewing it not as a single attitudinal response, but as a complex construct with several interrelated dimensions.

The research team employed a rigorous, multi-phase approach to develop the new QWL scale. This began with a qualitative phase involving focus groups with employees to elicit their understanding and experiences of QWL. This "bottom-up" approach ensured that the instrument’s content was grounded in the lived realities of workers, rather than being solely derived from existing theoretical frameworks. Following the qualitative phase, a Delphi procedure was used to refine the items, ensuring their relevance and importance. This process ultimately yielded 48 items that were then quantitatively validated.

Psychometric Rigor and Empirical Validation

The study administered the newly developed scale to 407 employees from a large non-profit social services organization. The data were subjected to extensive statistical analyses, including exploratory and confirmatory factor analyses, using polychoric correlations and Weighted Least Squares Mean and Variance (WLSMV) estimation to account for the ordinal nature of the response scale.

The analyses supported a hierarchical model where six distinct factors are organized under a higher-order QWL factor. These six factors represent key dimensions of working life:

• Factor 1: Organizational support, autonomy, and participation. This dimension captures the psychosocial and structural aspects of the work environment, emphasizing the extent to which employees feel supported by their organization and have a voice in their work.
• Factor 2: Working conditions and job fit. This relates to the adequacy of job demands and the alignment between the employee’s skills and the job’s requirements.
• Factor 3: Motivational and experiential aspects of intrinsic commitment. This dimension focuses on employees’ internal drive and engagement with their work.
• Factor 4: Professional development and career prospects. This reflects opportunities for growth, learning, and advancement within the organization.
• Factor 5: Social climate and interpersonal support. This dimension addresses the quality of relationships with colleagues and supervisors.
• Factor 6: Organizational justice, equity, and coherence. This pertains to the fairness of organizational processes, equitable treatment, and the consistency of organizational practices.

The hierarchical model demonstrated acceptable fit, indicating that the proposed structure accurately represents the relationships between the six dimensions and the overarching QWL construct. Internal consistency analyses, using measures like ordinal alpha and McDonald’s omega, showed high reliability for all dimensions and the overall scale, suggesting that the items within each dimension consistently measure the same underlying construct.

Furthermore, the study established measurement invariance across key demographic variables, including sex, job tenure, and professional group. This finding is crucial, as it indicates that the QWL scale functions similarly across these different groups, allowing for meaningful comparisons of QWL levels within and between diverse workforces. Configural and metric invariance were strongly supported, with generally acceptable scalar invariance, reinforcing the scale’s robustness.

Convergent and Discriminant Validity

To assess the construct validity of the new QWL scale, researchers examined its relationships with other theoretically related and distinct constructs. Convergent validity was supported by moderate to strong positive correlations between the QWL scale and measures of work engagement, job satisfaction, perceived organizational support, and mental wellbeing. These findings align with expectations, as a high quality of working life is logically associated with these positive psychological outcomes.

Discriminant validity was also demonstrated through generally low to moderate associations between QWL and theoretically distinct constructs such as personality traits (e.g., extraversion, conscientiousness), negative affect, and perceived stress. While negative correlations were observed with burnout indicators like cynicism and emotional exhaustion, and perceived stress, these relationships were not so strong as to suggest overlap with the QWL construct itself. This pattern suggests that the QWL scale captures a unique aspect of work experience, distinct from general personality predispositions or states of ill-being.

The study also employed advanced statistical techniques, such as partial correlations controlling for response styles and the heterotrait-monotrait ratio (HTMT), to ensure the robustness of its findings. These analyses further bolstered the evidence for both convergent and discriminant validity.

Theoretical and Applied Implications

The development of this hierarchically structured, multidimensional QWL instrument offers significant theoretical contributions. It provides a formal framework that integrates historical perspectives on QWL, bridging the gap between objective working conditions and subjective employee experiences. By conceptualizing QWL as a higher-order domain, the study clarifies its role as a potentially distal outcome variable that can be influenced by a range of organizational factors. This integrative view aligns with contemporary models like the Job Demands-Resources (JD-R) framework, suggesting that QWL may serve as a comprehensive evaluative construct that captures the cumulative effects of various job resources and demands.

For practitioners, the new QWL scale offers a valuable tool for organizational assessment and intervention. The multidimensional nature of the scale allows organizations to move beyond generic well-being initiatives and to identify specific areas within the work environment that may be hindering or enhancing employees’ quality of working life. For instance, if an organization scores low on the "organizational support, autonomy, and participation" dimension, interventions could be targeted at improving communication channels, empowering employees, and fostering a more supportive management style. Similarly, low scores on "professional development and career prospects" could signal a need for enhanced training programs or clearer career pathways.

The study’s authors emphasize that the instrument is intended as a profiling and monitoring tool, rather than a diagnostic screening device. This nuanced application allows for a data-driven approach to organizational development, enabling leaders to make informed decisions about where to invest resources for maximum impact on employee well-being and organizational effectiveness.

Limitations and Future Directions

Despite the robust methodology and promising findings, the study acknowledges several limitations. The research was cross-sectional, meaning it cannot establish causal relationships. Future research should employ longitudinal designs to examine the predictive validity of the QWL scale and to track changes in QWL over time in response to organizational interventions. Test-retest reliability studies are also recommended to assess the stability of QWL scores.

Additionally, the data were collected within a single non-profit social services organization. While this context provided a rich environment for exploring QWL, replication of the findings in diverse organizational settings, across different industries, and in various cultural contexts is essential to establish the generalizability of the scale. Independent cross-validation studies in larger, independent samples will also be crucial for further solidifying the scale’s psychometric properties.

Conclusion

The research by Jenaro and colleagues represents a significant step forward in the study of quality of working life. By developing and validating a theoretically integrated, multidimensional, and stakeholder-grounded instrument, the study offers a more precise and comprehensive way to assess QWL. This new scale promises to enhance both academic understanding and practical application in the field of organizational psychology, providing a much-needed framework for understanding and improving the work experiences of employees. The findings underscore the complexity of QWL, highlighting that it is shaped by a confluence of structural, contextual, and experiential factors, and that a multidimensional approach is vital for accurate assessment and effective intervention.
