Social support (current)
Social support is measured using The Multidimensional Scale of Perceived Social Support (Zimet, Dahlem, Zimet, & Farley, 1988). The scale has 12 items and 3 subscales (family, friends, and significant other) with 4 items each. Total scores range from 7 to 84 and each subscale score ranges from 4 to 28, with a higher score indicating greater social support. which are averaged together to get the total score. The total score is calculated by averaging the 12 items on the scale, and subscales are calculated by averaging the 4 items in each subscale.
Future orientation (current)
Future Orientation is the extent to which an individual thinks about and acts upon the future. This study assess future orientation using a scale developed by Chen & Vazsonyi (2011). The scale contains 6 items, but based on feedback from piloting, 2 items were omitted ("You will be killed by age 21" and "You will get HIV or AIDS") leaving 4 items in the final scale. The scale is calculated by averaging all items and ranges from 1 to 5, with higher scores indicating greater future orientation.
Work-hope scale (current)
Work-hope is a positive motivation state that is directed at work and work-related goals and is composed of the presence of work-related goals and both the agency and pathways for achieving those goals (Juntunen & Wettersten, 2006). The Work-Hope Scale (Juntunen & Wettersten, 2006) measures work-hope and consists of 28 items. Eight items from the scale are used in this study, which are averaged to get a total score ranging from 8 to 56, with higher scores indicating greater work-hope.
Self-determinism/Personal Growth Initiative (current)
The Personal Growth Initiative (PGI) Scale (Robitschek, 1998) is a 9-item scale that assesses an individual's active, intentional engagement in the process of personal growth. Items are summed to obtain a total PGI score, which ranges from 9 to 54, with higher scores indicating greater PGI.
Balance of possible selves (current)
Possible selves are the hypothetical images (the self one would like to attain, the self one would like to avoaid) critical for motivating action (Oyserman & Bybee, 2002). Open-ended questions from Oyserman, Bybee, Terry, and Hart-Johnson (2004) are used to assess number of possible selves, number of achievement strategies, and self-regulation scores. Responses are content-coded and then scored with higher scores indicating greater self-regulation.
Prevention and promotion orientation (Regulatory Focus) (current)
Regulatory Focus refers to the theory that people are motivated by two different types of regulation goals: promotion (eager pursuit of gains or successes) and prevention (striving to avoid negative outcomes) (Higgins, 1997). This study uses two scales to assess regulatory focus: (1) Strauman (2006) and (2) Lockwood, Jordan, and Kunda (2002).
The Strauman (2006) scale has 12 items, of which 8 are used in this study. There are two subscales, prevention and promotion, which are scored by averaging responses and range from 1 to 5 with higher scores indicating a greater prevention or promotion orientation.
The Lockwood, Jordan, and Kunda (2002) scale has 18 items, of which 10 are used in this study. There are two subscales, prevention and promotion, which are scored by adding responses and range from 5 to 54. The total score is calculated by subtracting the prevention score from the promotion score, with a higher score indicating a stronger promotion orientation.
