Full range indeed? The forgotten dark side of leadership

Characteristics of transformational leadership development programs: A scoping review

The effectiveness of transformational leadership (TFL) on various outcomes is well known. Accordingly, researchers have developed training programs to enhance TFL behaviours of leaders. Yet, no reviews summarizing the characteristics of TFL training programs exist. The purpose of this review was to examine the characteristics, reporting, and application of TFL-informed programs. A search of six databases yielded 4032 articles, 31 of which met the inclusion criteria. Program characteristics were analyzed using the Template for Intervention Description and Replication (TIDieR) checklist tool, while outcomes were analyzed according to the Kirkpatrick model of evaluation. The most common context for TFL program implementation was healthcare (n = 9). Programs were tailored and often delivered using group workshops and individual feedback. Studies reported variation in the dose of programs, rarely evaluated outcomes multiple times post-baseline, and typically employed Level 3a (subjective ratings of behaviour) evaluation measures. Reporting on program location, modifications, and fidelity was poor. Varying conceptualizations of TFL in different contexts lead to disparities in programs and protocols. Evaluation specialists should consider using tools like the TIDiER checklist to ensure that program characteristics are reported appropriately. Program planners should develop common approaches for planning and evaluating TFL programs to improve transparency and replicability of programs.

Abusive supervision: exploring the relationship with narcissism, self-promotion and unpredictability

Purpose

This study investigates whether subordinates who rate their managers higher on narcissism are also more likely to view their managers as abusive. In particular, the study explores the extent to which managers whom subordinates rate higher on narcissism use certain behaviors (self-promotion and unpredictability) that mediate the relationship between narcissism and perceived abuse.

Design/methodology/approach

Survey participants (n = 949) rated their most-destructive manager in terms of self-promotion, unpredictability, narcissism and abusiveness. A bootstrap analysis assessed the positive, mediating effects of leader self-promotion and unpredictability on the narcissism–abuse relationship.

Findings

Degree of perceived supervisor narcissism predicted subordinates' perceptions of abusive supervision. However, the supervisor's self-promotion activities and unpredictability fully mediated this relationship.

Research limitations/implications

This study identifies perceived narcissism as an antecedent of abusive supervision and identifies two mediators relevant to subordinates' perceptions of abuse. Using multiple methods and multiple sources, the authors recommend that scholars identify additional mediators. Further research should consider variables such as gender, organizational culture and occupational status.

Practical implications

Findings highlight how subordinates connect supervisor narcissism to abuse; this allows human resource practitioners to better predict and address subordinates' perceptions of their managers and to design interventions for improving supervisors' behaviors.

Originality/value

This study helps in explaining destructive leadership by empirically examining perceptions of narcissism as a driver of abusive supervision. Also, the study reveals the characteristics of narcissistic managers that impede productive relationships with subordinates.
