Autonomous motivation and support flourishes for individuals higher in collaborative personality factors: Agreeableness, assisted autonomy striving, and secure attachment.

INTRODUCTION: Individuals who strive autonomously for their goals, and who perceive autonomy supportive environments are more successful during goal pursuit. What dispositional factors predict autonomy flourishing during goal pursuit? METHODS: Four longitudinal studies were conducted over an 8-month academic year, and university students (Ntotal  = 1,544) completed surveys on motivation, support, and personality. Structural equation models were created using Mplus software to test whether collaborative personality factors were related to growth in autonomous motivation and autonomy support. RESULTS: All three distinct collaborative personality factors, trait Agreeableness, assisted autonomy striving, and secure parental attachment, were related to increases in autonomous motivation over the academic year. Conscientiousness, assisted autonomy, and secure attachment were related to increases in perceived autonomy support. A higher order latent collaborative traits factor, composed of Agreeableness, assisted autonomy, and secure attachment was found to be related to increased autonomous motivation and support over the academic year and resulted in increased goal progress. CONCLUSION: These results suggest that individuals higher in collaborative personality factors experience growth in personal autonomy during goal pursuit. Future research is needed to determine how to promote collaboration in goal pursuit to further help individuals successfully strive for their goals.

For the love of reading: Recreational reading reduces psychological distress in college students and autonomous motivation is the key.

OBJECTIVE: Reading is often cited as beneficial for one's mental health, but the research on this topic is limited. The goal of the present research was to examine whether recreational reading is beneficial for mental health during college, and to determine what motivates recreational reading. PARTICIPANTS: Participants were 231 university students from a large Canadian University. Methods: A longitudinal design was employed and students completed online surveys on recreational reading, motivation, psychological distress and need frustration at the beginning and end of the academic year. Results: Recreational reading was associated with reduced psychological distress over the school year. Recreational reading seemed to buffer against the frustration of one's basic psychological needs which led to improved mental health over the school year. Students who were more autonomously motivated reported reading more books recreationally. Conclusion: Recreational reading is a simple and cost-effective tool to help college students cope with mental health problems.

Polyethylene particles stimulate expression of ITAM-related molecules in peri-implant tissues and when stimulating osteoclastogenesis in vitro.

Wear particle-induced orthopaedic prosthesis loosening is associated with elevated osteoclast activity. The immunoreceptor tyrosine-based activation motif (ITAM)-related molecules OSCAR, FcRγ, TREM2 and DAP12 are important for osteoclast formation. The aim of this study was to determine if these molecules are involved in peri-implant loosening by investigating their expression in peri-implant tissues obtained at revision of joint replacement components containing polyethylene (PE) wear particles, and in osteoclasts formed in vitro in the presence of PE particles. The results showed that there was a marked and statistically significant increase in protein levels of the ITAM-related molecules in the revision tissues. The levels of OSCAR, FcRγ, TREM2 and DAP12 mRNA in the revision tissues were also increased. In vitro PE particles stimulated osteoclast resorption in the presence of 50 ng ml(-1) receptor activator NFκB (RANKL) and significantly elevated the expression of OSCAR, FcRγ, TREM2 and DAP12 during osteoclast formation. These findings suggest that the ITAM signalling molecules and their co-receptors have a role in pathogenic bone loss associated with implant PE wear.
