Health psychology: It's not what you do, it's the way that you do it.

Despite the growth in theoretical understandings of health behaviour and standardised approaches to health interventions (e.g. behaviour change taxonomies), health psychology has paid comparatively less attention to the importance of the implementation processes - 'how to' rather than 'what to' of such interventions.

Factors associated with physical activity referral completion and health outcomes.

Participant socio-demographic characteristics and referral reason were investigated in relation to completion and health outcomes in a Primary Care Physical Activity Referral Scheme using a prospective population-based longitudinal design. Participants (n = 1735) were recruited over a 2-year period. A three-stage binary logistic regression analysis identified the factors associated with the outcomes of completion (model 1), body mass reduction (model 2) and blood pressure reduction (model 3).

Physical activity counseling content and competency: a systematic review.

Background: Physical activity (PA) counseling is becoming commonplace in primary care settings, although there is a high degree of variation in the quality and quantity of this intervention. The purpose of this review was to examine the theory on which the intervention is based and the level of treatment fidelity applied at all stages of the intervention.

Methods: A systematic review was carried out for interventions that reported an element of PA counseling.
