ABSTRACT To develop and field test the Multidimensional Acceptance of Loss Scale to measure disability acceptance based on the four value changes identified by Beatrice Wright.
Quantitative descriptive design using exploratory factor analysis to determine the factorial validity of the Multidimensional Acceptance of Loss Scale.
The Canadian Paraplegic Association.
One hundred and sixty-one members of the Alberta, Saskatchewan, Nova Scotia and Manitoba chapters of the Canadian Paraplegic Association were recruited for the current study.
A four-factor structure accounting for 50% of the total variance was found for the Multidimensional Acceptance of Loss Scale. The internal consistency reliability coefficients (Cronbach's alpha) for the four factors ranged from 0.80 to 0.88. Three clusters of participants with high, moderate and low disability acceptance were identified based on their profiles of Multidimensional Acceptance of Loss Scale subscale scores using cluster analysis. MANOVA results indicated that participants in the three clusters significantly differed on self-esteem, F(2, 154) = 19.78, P < 0.001 and quality of life, F(8, 236) = 5.16, P < 0.001. Participants with high Multidimensional Acceptance of Loss Scale scores have higher self-esteem and quality of life scores than those with lower scores.
The Multidimensional Acceptance of Loss Scale was found to measure the four value changes in Beatrice Wright's disability acceptance theory in a sample of Canadians with spinal cord injuries. It demonstrated good internal consistency reliability and construct validity.

    ABSTRACT: To investigate the correlation of higher-order coping strategies of tenacious goal pursuit and flexible goal adjustment with adjustment after rehabilitation in spinal cord injury. Cross-sectional correlational study. All 397 eligible patients entered for spinal cord rehabilitation between 1999 and 2009 were contacted and 130 (33%) agreed to complete a self-report questionnaire. Partial correlations were computed between tenacious goal pursuit and flexible goal adjustment and affective and cognitive psychological adjustment. Demographics, spinal cord injury related variables, social support and coping were used as control variables. After controlling for relevant demographic, medical and social support indices, partial correlations between tenacious goal pursuit and indices of adaptation were not significant. Significant partial correlations were observed between flexible goal adjustment and each of the indices of adjustment (r = -0.33, -0.42, 0.51, -0.38, respectively, for depression, anxiety, acceptance, and helplessness) after controlling for all relevant variables in the model. Flexible goal adjustment explained significant additional proportions of variance for each of the adjustment indices (7%, 11%, 18%, and 7%, respectively). Flexible goal adjustment, but not tenacious goal pursuit, is associated with psychological adjustment in spinal cord injury. Further research is needed to understand the mechanisms of flexible goal adjustment. Interventions targeting flexible goal adjustment might be of benefit for the patient.
