Possible selves researchers have uncovered many issues associated with the current possible selves measures. For instance, one of the most famous possible selves measures, Oyserman (2004)'s open-ended possible selves, has proven to be difficult to score reliably and also involves laborious scoring procedures. Therefore, this study was initiated to develop a close-ended measure, called the Persistent Academic Possible Selves Scale for Adolescents (PAPSS), that meets these challenges. The PAPSS integrates possible selves theories (personal and social identities) and educational psychology (self-regulation in social cognitive theory). Four hundred and ninety five junior high and high school students participated in the validation study of the PAPSS. I conducted confirmatory factor analyses (CFA) to compare fit for a baseline model to the hypothesized models using Mplus version 7 (Muthén & Muthén, 2012). A weighted least square means and a variance adjusted (WLSMV) estimation method was used for handling multivariate nonnormality of ordered categorical data. The final PAPSS has validity evidence based on the internal structure. The factor structure is composed of three goal-driven factors, one self-regulated factor that focuses on peers, and four self-regulated factors that emphasize the self. Oyserman (2004)'s open-ended questionnaire was used for exploring the evidence of convergent validity. Many issues regarding Oyserman (2003)'s instructions were found during the coding process of academic plausibility. It was complicated to detect hidden academic possible selves and strategies from non-academic possible selves and strategies. Also, interpersonal related strategies were over weighted in the scoring process compared to interpersonal related academic possible selves. The study results uncovered that all of the academic goal-related factors in the PAPSS are significantly related to academic plausibility in a positive direction. However, self-regulated factors in the PAPSS are not. The correlation results between the self-regulated factors and academic plausibility do not provide the evidence of convergent validity. Theoretical and methodological explanations for the test results are discussed.

This study utilized targeted messages and expert and referent sources in an effort to promote physical activity behavior in college students. College students aged 18-25, excluding collegiate athletes, were randomized into three conditions using their current physical activity level. Two of the conditions received targeted messages highlighting three primary components of social cognitive theory - self-efficacy, outcome expectations, and goals - while the third condition received no messages. In addition, the experimental conditions received the messages from either an expert (i.e., a personal trainer) or a referent (i.e., a close friend). In this way, this experiment analyzed whether receiving social cognitive theory messages increased physical activity indicators compared to the control condition, as well as if the message source caused differences in the physical activity indicators. Moreover, participants completed Time 1 and Time 2 measures to determine if receiving messages or not caused changes over a one week time period. Seven physical activity indicators were assessed: self-efficacy, positive outcome expectations, negative outcome expectations, attitudes, response-efficacy, intentions, and physical activity behavior. Results revealed that both the personal trainer and close friend conditions had significantly higher scores than the control condition for intentions at Time 1 and Time 2, as well as physical activity behavior at Time 2. Moreover, the personal trainer condition had significantly higher positive outcome expectations compared to both the friend and control conditions. No other significant differences were found across conditions for Time 1 attitudes, response-efficacy, negative outcome expectations, self-efficacy, and Time 2 attitudes, and self-efficacy. Overall, targeted messages were effective in increasing physical activity intentions and behavior regardless of the message source.
