Several new potential mediators as well as previously identified mediators were identified (eg. fear of the unknown and competitiveness). Most of the potential strategies were seen to be feasible; however, differing views existed among children, parents and teachers.These findings will inform the development of effective strategies for promoting children's physical activity by identifying the most appropriate potential mediators to be targeted. The purpose of this study was to investigate whether degrees of self efficacy (SE) are associated with physical activities or psychological factors after self-monitoring intervention. The subjects found in this study consisted of 49 female college students. We put the subjects in three groups, according to ones degree of SE: high SE group, middle SE group and low SE group. We conducted an intervention study using group cognitive-behavioral intervention including the selfmonitoring method. We performed a psychological assessment in order to exam SE, self esteem and stress responses, while also applying experimental protocol in the pre, intervention and post period stages. ANOVA of exercise volume disclosed significant group × period interaction. The significant period effect was disclosed in exercise volume and total energy expenditure. In the post period, low SE group showed a significantly lower exercise volume than high SE group. Low SE group had a significantly lower exercise volume, total energy expenditure and step counts in the post period compared in the intervention period. It should be noted that this pilot study was conducted without a follow up period. In the future, we need to examine whether self-monitoring intervention effects physical activities in a follow up period. In conclusion, after we applied group cognitive-behavioral intervention including the self-monitoring method, we discovered that high SE promoted the habituation of exercise while also inhibiting the risk of rebound. Apathy was decreased in only the subjects categorized with low SE using group cognitivebehavioral intervention including the self-monitoring method. Spondyloarthropathies (SpA) consist of a group of chronic inflammatory diseases characterized by symptoms of back pain, stiffness, fatigue, and sleep disturbance. While regular exercise has been shown to be beneficial and is recommended as part of patient selfcare, little is known regarding intention to initiate, alter, or maintain exercise in this patient population. This study examined the distribution of exercise stages of change and the biopsychosocial factors which differentiate readiness to exercise among individuals with SpA. Demographic and clinical data (comorbid disease, disease duration), along with self-report standardized questionnaires assessing functional disability, disease activity, depressed mood, perceived stress, leisure time physical activity, exercise self-efficacy, exercise pros and cons and exercise stage of change were collected crosssectionally from a sample of 125 individuals with SpA. Data were analyzed by frequency analysis, ANOVA and chi-square. Fifty-two percent (52%) of the participants were in the action/maintenance stages for exercise adoption and 49% in the preaction stages (precontemplation=20.8%; contemplation=13.6%, preparation 13.6%). Patients in the preaction stages had more disease activity (p<.005), more functional disability (p<.001), higher perceived stress (pp=.008) and reported lower self-efficacy (p=.003) and less barriers for exercise (p=.008). Gender, age, socioeconomic status (i.e. education, income) and exercise pros did not differ across the stages. These findings suggest that strategies designed to improve exercise self-efficacy, reduce exercise barriers and emphasize the functional and emotional (i.e. stress reducing) health benefits associated with physical activity may be useful for patients with SpA who are less motivationally ready to engage in regular exercise. Regular leisure-time physical activity behavior is achieved by fewer than 50% of Americans. If it were possible to decrease the cognitive load associated with deciding to exercise, it might be easier to adhere to a regular exercise routine, as it becomes an automatic activity that does not require decision making; this type of behavior would be termed by theorists to be a "habit." However, empirical evidence is lacking as to whether those individuals who have successfully instituted a regular exercise routine have such aspects of "habit" in their behavior patterns. The present study reports the level of habit formation among regular exercisers using a survey format. The Self-Report Habit Inventory (SRHI) (Verplanken & Orbell, 2003) measures the subjective sense of habit formation. The present exploratory study surveyed a sample of individuals (n= 176) who attended a fitness club in a metropolitan area using the SRHI (with a 7-point Likert scale), as well as objective questions about regularity of behavior (frequency and constancy of time, place, and weekly and seasonal patterns).
