Mental skills for musicians: Managing music performance anxiety and enhancing performance. - 1 views

  • did notreturn any recent studies investigating the effec-tiveness of a purely cognitive intervention in thetreatment of MPA; consequently, research inthis particular area is needed
  • Past re-search has focused on combined interventions;however, often these programs run for over 6weeks and it is unknown which aspects of theintervention are most effective (e.g., Nagel,Himle, & Papsdorf, 1989)
  • State–Trait Anxiety Inventory (STAI).The STAI is widely used in anxiety researchand is considered to be a valid and reliable scale(Kenny, 2006).

  • Researchers have found that MPA af-fects instrumentalists and vocalists of all agesand abilities, including students, professionals,amateurs, and children (Brotons, 1994; Kenny,2006; Liston, Frost, & Mohr, 2003)

  • The cognitive intervention had no significanteffect on anxiety levels. Sweeney and Horan’s(1982) study indicated that a cognitive restruc-turing program may be helpful in the treatmentof MPA; their program, featuring cognitive re-structuring, significantly reduced anxiety.

  • Imagery is a mentalexercise that can help athletes maintain concen-tration, decrease anxiety, and improve confi-dence; thus, it may also be helpful for somemusicians (Gregg & Clark, 2007).

  • MPA is a pervasive problem affecting musi-cians of all ages and abilities. As compared withthe research on mental skills training in athletes,relatively little is known about the assessment,treatment, and theoretical underpinnings ofMPA
  • Kenny (2006) suggested that improving perfor-mance quality will have a positive, self-reinforcing effect on the musician and enhanceconfidence in future performances.
  • We predicted that anxiety levels would de-crease in the treatment group from pre- to post-test. This hypothesis was partially supported.Specifically, there was a significant reductionon the PAI in the treatment group. Although theparticipants improved after the intervention,they were still not within the optimal rangeaccording to Nagel et al. (1981
  • Although the decrease in anxiety was notas large in our study, our participants droppedfrom the high performance anxiety category tothe moderate performance anxiety category
