The Effects of a Video-Aided Imagery Intervention upon Collective Efficacy in an International Paralympic Wheelchair Basketball Team

Abstract

A multiple baseline across groups design was used to examine the effects of an imagery intervention on perceptions of collective efficacy. Members (n = 10) from an international wheelchair basketball team were separated into three regional intervention groups. Each group completed a 4 week, video-aided, motivational general–mastery (MG-M) type imagery program with team content. Collective efficacy was measured via the Collective Efficacy Inventory (Callow, Hardy, Markland, & Shearer, 2004). Collective efficacy increased for the South group and became more consistent for the Midlands group. No changes were reported for the North group. Social validation measures indicated potential mechanisms via imagery effects on individual perceptions of self-efficacy and then collective efficacy. The results provide partial support for the use of MG-M type imagery interventions to enhance both individual and team perceptions of collective efficacy in elite wheelchair basketball.

Action Observation and Imagery Training Improve the Ease With Which Athletes Can Generate Imagery

“…Indeed, engaging in combined imagery and observation Downloaded by [New York University] at 22:01 14 May 2015 has been shown to activate the cortical motor system to a greater extent than observation or imagery alone (e.g., Berends, Wolkorte, Ijzerman, & van Putten, 2013;Macuga & Frey, 2012;Sakamoto, Muraoka, Mizuguchi, & Kanosue, 2009;Villiger et al, 2013; for a review, see Vogt, Di Rienzo, Collet, Collins, & Guillot, 2013). There is also limited evidence that combined imagery and observation is effective in improving motor skill performance (e.g., Atienza, Balaguer, & Garcia-Merita, 1998) and perceptions of collective efficacy in sport performers (Shearer, Mellalieu, Shearer, & Roderique-Davies, 2009). As such, instructing athletes to engage in the kinesthetic imagery of a movement while observing it may activate the motor system to a greater extent than observation or imagery alone.…”

Benefits of Combined Mental and Physical Training in Learning a Complex Motor Skill in Basketball

“…Recent studies have attempted to assess motor imagery effects through self-reported measures, like the Standardized Basic and Combined Movements Scale (Dossoulin & Rehbein, 2011) or the Sport Imagery Questionnaire (Hall et al, 1998). These studies aim at identifying the role of imagery training in improving psychological issues like self or collective efficacy (Shearer et al, 2009) or the imagery ability itself (Cumming et al, 2001). Other studies analyze the outcome from a mathematical perspective with a specific parametric analysis of distances and angles of the movements, e.g.…”

Development and validation of the Wheelchair Imagery Ability Questionnaire (WIAQ) for use in wheelchair sports

“…Previous research has attempted to make some basic, initial adaptations to existing but predominately "able bodied centric" psychometrics. Shearer, Mellalieu, Shearer & Roderique-Davies (2009) identified that the original Vividness of Movement Imagery Questionnaire (VMIQ; Isaac, Marks & Russell, 1986) was designed for able-bodied athletes, in other words those who have functional capacity in all limbs. As such, some of the items would not be relevant to those who do not have lower limb function (e.g., Spina Bifida, Spinal Cord Injury, Polio).…”
