A Protection Motivation Theory Approach to Understanding How Fear of Falling Affects Physical Activity Determinants in Older Adults.

Objectives: This study applied an extended Protection Motivation Theory to investigate the relative importance of fear of falling (FoF) among motivational and intentional determinants of physical activity (PA) behavior.

Methods: Older U.S.

Predicting Decisional Determinants of Physical Activity Among Older Adults: An Integrated Behavior Approach.

ObjectivesThe present study applied the Integrated Behavior Change Model to investigate how behavioral decisions are predicted, namely, intention, planning, and habits, with respect to physical activity. Participants were older adults (ages 65+) residing in the U.S.

Differences and similarities of physical activity determinants between older adults who have and have not experienced a fall: Testing an extended health belief model.

Purpose: Experiencing a fall can be a detrimental experience for older adults and may affect an individual's beliefs about participating in future physical activity (PA) behavior. The purpose of this study was to identify if determinants of PA differ between older adults who have a history of a fall (HF) and those with no history of a fall (NHF) within the Health Belief Model (HBM), expanded through the constructs of intention and habit.

Materials And Methods: Participants (N = 667) were community-dwelling older adults who completed online measures of original HBM determinants (beliefs, barriers, self-efficacy, cues, and perceived threat variables) related to participating in PA in addition to past PA behavior and intention.
