The MSES is a 16 item self-report measure of self-efficacy related to everyday life activities, designed specifically for persons with SCI. Individuals use a 7-point Likert scale ranging from 1 (very uncertain) to 7 (very certain) to rate their ability to perform 16 everyday tasks, with higher scores representing greater perceived self-efficacy. A Total Score, ranging from 16 to 112 is calculated by summing all item responses. The MSES has been used in previous studies of SCI, and demonstrates excellent internal consistency (alpha = 0.91 - 0.93), high reliability, and good convergent, concurrent and divergent validity. Time to administer: 5 to 10 minutes.

The GSES is a questionnaire designed to assess a person's ability to cope with a variety of difficult demands in life, with ten items scored using a Likert rating scale, ranging from 1 (not at all true) to 4 (exactly true). This scale has acceptable internal reliability (ranging from.73 to .90) and criterion validity, as demonstrated by positive correlations with positive emotions, optimism, and work satisfaction, and negative correlations with anxiety, stress, depression, and health complaints. The GSES has been used and validated in numerous populations and cultures, including people with SCI. This self-administered scale produces a Total Score ranging from 10-40, with higher scores indicating greater general self-efficacy. Time to administer: 3 to 5 minutes.

The SWLS is a five item measure on which respondents rate their life satisfaction using a 7-point Likert scale, ranging from 1 (strongly disagree) to 7 (strongly agree). A Total Score is calculated by summing each of the items, having a range of 5 to 35, with higher scores representing greater perceived quality of life. This measure has well established psychometric properties, with high reliability (.79 to .89), good content validity, criterion validity, and has been extensively used in research regarding people with SCI. Time to administer: 1 to 3 minutes.

The PART-O is a 17-item assessment of participation and has demonstrated good psychometric properties in measuring participation for people living with disabilities. The PART-O has acceptable reliability and validity for persons with SCI. An Averaged Total Score is computed by taking the mean of 17 items, with scores ranging from 0 (never participate in these types of activities) to 5 (almost always participate in these types of activities), with higher scores representing greater participation. This assessment will be utilized to measure overall participation. Time to administer: 8 to 10 minutes.

The PHQ-9 is a 9 item scale that will be used to assess depression. Respondents rate the frequency at which specific problems have been bothersome during the past two weeks, using a four point scale ranging from 0 (not at all) to 3 (nearly every day). A total score is calculated by summing all items, with higher scores indicating an increasing severity of depression. This scale demonstrates excellent psychometrics, with excellent internal consistency (α = 0.86 - 0.89), high test-retest reliability (0.84) and good criterion and construct validity and has been used extensively in populations with SCI. Time to administer: 1 to 3 minutes.

The GAD-7 is a brief 7 item measure that will be used to assess the severity of general anxiety. Using a four point Likert scale ranging from 0 (not at all sure) to 3 (nearly every day), respondents rate how often they have been bothered by specific symptoms during the past two weeks. A total severity score, ranging from 0 to 21, is calculated by summing all items. This measure has demonstrated high internal consistency (α = .89 - .92), good test-retest reliability (icc = .83) and adequate convergent and discriminant validity. This scale has been used in previous studies involving persons with SCI. Time to administer: 1 to 3 minutes.
