Effect of Manipulating Descriptive Norms and Positive Outcome Expectations on Physical Activity of University Students During Exams

ABSTRACT This experimental study examined the interaction between messages conveying different levels of descriptive norms and positive outcome expectations on university students’ engagement in moderate and vigorous physical activity over an exam period. Using a pre–post design, university students entering a final examination period (N = 74) were randomly assigned to one of four message conditions, receiving a message motivating them to exercise over the exam period. Messages included both a descriptive norm (how many others reported being active during a previous exam period; high vs. low) and a positive outcome expectation (those who exercise during exams report better grades; high vs. low). The results from an analysis of covariance (ANCOVA), controlling for baseline levels of daily physical activity, revealed a significant interaction. Post hoc analyses indicated that when the descriptive norm was high, those who received a high positive outcome expectation reported being more active during the exam period compared to those receiving the low positive outcome expectation. Results provide preliminary support for the idea that activity during an exam period can be positively influenced if individuals are presented with normative messages that (a) many others are being active during the exams and (b) many of those being active also are benefiting academically.

Physical Activity in the Transition to University: The Role of Past Behavior and Concurrent Self-regulatory Efficacy

Abstract Objective: Two studies were conducted to examine the relationship between past physical activity, concurrent self-regulatory efficacy (CSRE), and current physical activity during the transition to university. Participants: Study 1 included 110 first-year undergraduate students recruited during October/November of 2012. Study 2 involved 86 first-year undergraduate students recruited during October/November of 2013. Methods: Surveys were completed online, concurrently (Study 1) and prospectively (Study 2). Results: CSRE was found to positively predict current physical activity participation in both studies. However, the relation of CSRE to physical activity was attenuated when past behavior was taken into account. Conclusions: Physical activity is one goal that university students pursue concurrently with other goals. Not only is current planned activity related to ones past participation in physical activity, it is also related to self-regulatory beliefs about managing that activity in the new context of university life.

Examining the Relationship between Message Variables, Affective Reactions, and Parents’ Instrumental Attitudes toward Their Child’s Physical Activity: The “Mr. Lonely” Public Service Announcement

This study examined the relationship between message variables and affective reactions with parents’ attitudes after seeing a physical activity mass media public service announcement (PSA). It was hypothesized that there would be a positive relationship between message variables (i.e., personal relevance, novelty of information, and feelings toward sponsoring organization) and parents’ attitudes toward their child/children’s physical activity after viewing the PSA. Furthermore, we explored whether discrete affective reactions were related to attitudes, beyond the effect of message variables. A secondary data analysis was conducted with parental responses to an online campaign evaluation survey (n = 267). Hierarchical regression analyses showed an overall positive relationship between all three message variables and attitudes. Furthermore, two discrete affective reactions were positively related to attitudes. Parents who endorsed feeling motivated or guilty after viewing the advertisement had more positive attitudes toward their children’s physical activity levels. This study represents an ecologically valid assessment of how message variables and affective reactions are related to attitudes within the context of a physical activity mass media campaign. The results provide guidance for the effective design of mass media physical activity campaigns.
