  • Authentic leaders, energized employees? Indirect beneficial and adverse effects of authentic leadership on intrinsic motivation and exhaustion

    Open AccessLucas A Maunz, Sascha Thal et al.ARTICLEApplied Psychology2024

    Current research is unclear regarding the associations between authentic leadership (AL), intrinsic motivation, and exhaustion. Following self‐determination theory (SDT), we hypothesize that AL indirectly increases intrinsic motivation and decreases exhaustion by increasing basic psychological need satisfaction (BPNS). We propose that these processes occur through increased AL in leader‐employee interactions and a higher average display of AL. To…

    While the potential of serotonergic psychedelics and related substances as adjuncts in substance-assisted psychotherapy (SAPT) has been investigated for the treatment of several disorders, evidence for the appropriate therapeutic conduct in administration sessions is sparse. In this article, we discuss the current evidence for best therapeutic practice during administration sessions with serotonergic psychedelics and entactogens as adjuncts to ps…

    Research into psychedelic-assisted psychotherapy (PAP) is rapidly increasing with best practice guidelines being continuously updated. Yet the key principals of such guidelines are based on evidence accumulated during earlier research into these treatments and trans-disciplinary psychotherapeutic knowledge. One area of practice-based evidence that has not been considered is that accumulated by people who use psychedelics (PWUP) outside of clinica…
