The development of a locus of control measure predictive of injured athletes' adherence to treatment.

The Sports Rehabilitation Locus of Control (SRLC) scale was developed to facilitate study of the behaviour of athletes recovering from injury. The SRLC was built specifically to assess locus of control in injured athletes by adapting selected items from the Multidimensional Health Locus of Control (MHLC) questionnaire developed by Wallston, Wallston, & DeVellis (1978), and in accordance with their rationale for the construction of domain-specific LOC scales. The resultant locus of control measures (internal, powerful others, and chance) were administered (along with the MHLC) to a sample of 145 sports-injured athletes. Good internal consistency (alphas ranged from .72 to .79) and test-retest reliability (correlations ranged from .75 to .85) was shown by the SRLC scales, and the pattern of inter-scale correlations supported the three-factor conceptualisation of locus of control on which the SRLC was based. In the subsequent initial validation study, the relationship between SRLC scale scores and adherence to treatment was tested with a sample of injured athletes. Encouragingly, internality was positively associated p<.05 with treatment adherence.

Sports participation in individuals with spinal cord injury: demographic and psychological correlates.

The factors associated with involvement in sport were surveyed in a sample of 121 adults (aged 16 to 60 years) with spinal cord injury. The subjects responded to a questionnaire requesting data on personal characteristics and injury variables, and completed measures of depression (Centre for Epidemiological Studies Depression Scale) and trait anxiety (Spielberger's State Trait Anxiety Inventory). Univariate analysis showed that although sport participants (n = 67) did not differ significantly from nonparticipants (n = 54) on any of the psychometric measures, they were younger, had sustained their injury at an earlier stage, reported higher incomes, and were less likely to have sustained cervical-level damage. A hierarchical discriminant function analysis revealed that the significant predictors discriminating sport participants from nonparticipants were age and income. These findings suggested that, at least for this sample of individuals with spinal cord injury, post-injury involvement in sport was not specifically associated with indices of psychological adjustment.
