“…For example, trials that have tested the direct and moderator effects of planning interventions on health behaviour have tended to be on relatively small samples, recruited at convenience or from homogenous groups, and they have, as a consequence, tended to be underpowered (e.g. Arbour & Martin Ginis, 2004;Brawley, Arbour-Nicitopoulos, & Martin Ginis, 2013;Latimer, Martin Ginis, & Arbour, 2006;Murray, Rodgers, & Fraser, 2009). The sparseness of the research and the limitations of the current study and those that have been conducted previously present considerable problems in identifying the true effects of moderators of planning interventions on health behaviour.…”
