Mental imagery-based self-regulation: Effects on physical activity behaviour and its cognitive and affective precursors over time.

ABSTRACT:

Objectives

(1) Test whether a mental imagery-based self-regulation intervention increases physical activity behaviour over 90 days; (2) Examine cognitive and affective precursors of change in physical activity behaviour.

Design

A randomized control trial with participants (N = 500) randomized to one of six intervention conditions in a 3 (risk communication format: bulleted list, table, risk ladder) x 2 (mental imagery behaviour: physical activity, active control [sleep hygiene]) factorial design.

Methods
