Kupferstein (2018) surveyed 460 respondents and found that 46 percent of respondents met the diagnostic threshold for posttraumatic stress disorder after exposure to applied-behavior-analysis-based intervention. The purpose of this paper is to provide an evaluation a critical analysis of Kupferstein (2018) including the experimental methods and discussion of the results.

The authors evaluated the Kupferstein’s methodological rigor with respect to the use of hypothesis testing, use of indirect measures, selection of respondents, ambiguity in definitions, measurement system, and framing of the experimental question when conducting the correlational analysis in addition to Kupferstein’s analysis and discussion of the results.

Based upon the analysis, Kupferstein’s results should be viewed with extreme caution due to several methodological and conceptual flaws including, but not limited to, leading questions used within a non-validated survey, failure to confirm diagnosis, and incomplete description of interventions.

It is the authors’ hope that this analysis provides caregivers, clinicians, and service providers with a scientific lens which will useful in viewing the limitations and methodological flaws of Kupferstein.

Leading with vision while granting employees autonomy is one effective organizational response to the demands of a dynamic external environment. The former is thought to align followers' behavior by providing guidance, the latter to increase variance in their behavior by relinquishing control; both exert beneficial but distinct effects on organizational performance. What has remained uncharted heretofore is how these leader behaviors shape their followers' cognition and, subsequently, yield improvements in performance. The authors argue that a leader's vision communication transforms followers' cognitive representation of their work. This not only enables them to specify their goals in alignment with the vision (goal clarity) but also to locate the meaning of their work within the bigger picture of the vision (construal level). By contrast, perceived autonomy in terms of power-sharing might directly affect followers' work engagement more narrowly.

The authors tested the model on a sample of 408 employees from eleven enterprises of a holding company. In the survey, employees reported perceived vision communication and autonomy provided by their leader. Furthermore, the authors assessed the employees' goal attainment. To capture how employees represent their daily work activities, the authors measured their construal level and their goal clarity.

The results show that both perceived vision communication and granted autonomy improve employees' goal achievement. Moreover, two processes mediate the relationship between vision communication and goal achievement in followers: first, specifying goals in terms of clarity; second, composing a higher-level mental construal of their work. In contrast, no mediation of empowering leader behaviors was found.

Better goal achievement through visionary leadership is therefore achieved through cognitive alignment of followers, while leader-granted autonomy acts as a motivational tool directly on performance.
