Section 1

Question Answer
Edmmunds 2008: overviewtwo exercise class groups. 25 in SDT intervention, 31 in control group. 10 week duration, monitoring and questionnaires throughout
What is autonomy support?Autonomy support refers to the provision of choice and meaningful rationale from those in a position of authority, acknowledgment of the perspective of others and minimization of pressure (Deci, Eghrari, Patrick, & Leone, 1994). For example, an exercise instructor who is behaving in an autonomy supportive manner will see the situation from the exercisers’ perspective and encourage them to make their own decisions. He/she would not try to impose his/her own perspective on them, or attempt to make them change.
Edmmunds 2008: Three factors of instructingautonomy support, structure and interpersonal involvement
Edmmunds 2008: Two main objectivescan instructors teaching style be manipulated so it is perceived to provide autonomy support, structure and interP involvement AND what are the impacts of this on SDT variables ie psychological needs, motivation and outcomes.
Edmmunds 2008: manipulating instructor techniquesautonomy support decreased in control group. autonomy support and interpersonal involvement increased significantly in the SDT group
Edmmunds 2008: resultscompetence increased in control. competence increased MORE in intervention group. relatedness also increased in intervention group. introjected regulation increased in the control group whereas amotivation decreased. intervention group did not show difference to control group in motivations. Intentions decreased in control group. intervention group showed increase in positive affect. Attendance was lower in control group than intervention group.
Edmmunds 2008: limitationsnot randomised, same instructor for both classes. Subsequent work would benefit from a cluster randomized design which considers levels of potentially important discriminating variables, such as pre-existing psychological need satisfaction, autonomous motivation for physical activity engagement and past history regarding exercise involvement, on entry to the programme

Section 2

Question Answer
Grant 2015: purposeHealthy adult participants (N =130) who identified strongly with an exercise referent group reported higher levels of physical activity, and this relationship was mediated by self-efficacy and outcome expectations. This study adds to the existing literature on the effects of social groups on health and is one of the first to examine the interplay of personal factors and group membership on physical activity
Grant 2015: hypothesisinfluences on individuals focussed on constructs of cohesion, social norm and sunjective norms - inconsistent predictors of PA. in this research, personal factors (self-efficacy and outcome expectations) and social group influences are measured. hypothesize that selfefficacy and outcome expectations mediate the group identification-physical activity relationship.
Grant 2015: SCT and self-efficacy and outcome expectationsSCT: According to SCT, efficacy beliefs and outcome expectations are influential bases for action. Self-Efficacy: predictor of adoption and maintenance of exercise. Outcome Exp: more likely to initiate and maintain if perception of outcomes is favorable and satisfiable.
Grant 2015: the five current recommendations from literature to improve PA1. specific plans. 2. specific recommendations about where, when and how. 3. positive feedback reinforcing efforts. 4. highlight positive outcomes. 5. draw attention to performance of others to induce change
Grant 2015: group belonging-nessIn contrast, we suggest that a more powerful mechanism for adopting these strategies may be group belongingness—it is when people identify strongly with a social group that promotes the targeted health behavior that they are most likely to adopt these exercise-related strategies.
Grant 2015: method and resultscross-sectional questionnaire. Results showed that participants who identified strongly with an exercise-referent group reported being more physically active and this relationship was mediated by selfefficacy and positive outcome expectations.
Grant 2015: limitationsactive adults. self report. non-experimental.

Section 3

Question Answer
Strachan 2012: purposeWe examined the relationship between role and group identity among runners. Further, the relationship of runner role and running group identity were examined relative to social cognitive and behavioural outcomes relative to running and the possibility of running group disbandmen Role and group identity and adjustment to the possibility of running group disbandment.
Strachan 2012: methodobservational. measures of runner role and running group identity, self-efficacy, recent exercise and reactions to group disbandment.
Strachan 2012: resultsrunner role and running group were positively related. runner role was associated with better self-efficacy, vigorous exercise, less group running and adaptive reactions to possibility of disbandment. Running group identity was associated with neg, self-efficacy, more group runs, and maladaptive responses to disbandment.
Strachan 2012: conclusionrole and group identities are related but different. dentification as a runner may not only be associated with exercise in the context of the group but may also have protective effects against disruptions to group running. Identification with the running group may compromise exercise in the face of group disbandment Role and group identity and adjustment to the possibility of running group disbandment.

Section 4

Question Answer
Fortier 2012: purposeSDT relevance in design, delivery and testing of PA interventions.
Fortier 2012: PAC (physical activity counselling) interventioninfluence quantity and then quality of motivation using intensive autonomy supportive counselling (3x inperson sessions, 3x telephone sessions). based on SDT-MI. TPB aligns well with motivation quantity. improved both quantity and quality of motivation.
Fortier 2012: The Empower Trialeffect of PA promotion programme delivered by a health and fitness advisor. Used MI again. Participation in control and intervention group meant both physical activity levels and mental health improved, with no difference between groups. Autonomy support from any HFA lead increased self-determination. But not many significant findings when training HFAs in SDT.
Fortier 2012: Promotion of Health and Exercise in Obesity (PESO) trialRCT for overweight women, 1yr intervention, 2yr follow up. autonomy supportive environment, weekly classes for 30 weeks. Highly successful in changing PA levels, differences remained highly significant at 2yr follow up. increased autonomous self-regulation, perceived competence, and enjoyment.
Fortier 2012: summaryeven when interventions are not successful in affectiong theory based constructs, the same sonstructs can be found to predict positive behavioural and psychological outcomes in both conditions. monitor for "therapist drift". fidelity of intervention delivery needs to be better addressed in future. HFAs may already have patients best interests at heart shown in Empower.
