Objective: Goal setting is a common feature of behavior change interventions, but it is unclear when goal setting is optimally effective. The aims of this systematic review and meta-analysis were to evaluate: (a) the unique effects of goal setting on behavior change, and (b) under what circumstances and for whom goal setting works best.Method: Four databases were searched for papers that assessed the unique effects of goal setting on behavior change using randomized controlled trials. 141 papers were identified from which 384 effect sizes (N = 16,523) were extracted and analyzed. A moderator analysis of sample characteristics, intervention characteristics, inclusion of other behavior change techniques, study design and delivery, quality of study, outcome measures and behavior targeted was conducted.Results: A random effects model indicated a small positive unique effect of goal setting across a range of behaviors, d = .34 (CI = .28 to .41). Moderator analyses indicated that goal setting was particularly effective if the goal was: (a) difficult, (b) set publicly, and (c) was a group goal. There was weaker evidence that goal setting was more effective when paired with external monitoring of the behavior/ outcome by others without feedback and delivered face-to-face.
Conclusions: Goal setting is an effective behavior change technique thathas the potential to be considered a fundamental component of successful interventions. The present review adds novel insights into the means by which goal setting might be augmented to maximize behavior change and sets the agenda for future programs of research.2 KEYWORDS: goal setting, behavior change, randomized controlled trials, metaanalysis, systematic review
Public Health SignificanceThe findings reported in the present review show that goal setting is an effective behavior change technique that can be considered a fundamental component of successful behavior change interventions.Findings suggest that optimally goals should be: (a) difficult but achievable, (b) set publicly, (c) set face to face, (d) set as a group goal and (e) set without drawing attention to goal commitment. There is also some indication that goal setting is particular effective in certain samples (i.e., school children, general population, male, younger people and those of Asian ethnicity) in particular settings (i.e., schools and workplaces).

Unique Effects of Goal Setting on Behavior Change: Systematic
Review and Meta-AnalysisA goal is "the object or aim of an action" (Locke & Latham, 2002, p. 705) and goal setting is one of the fundamental techniques that public bodies and government agencies recommend to promote behavior change (e.g., NICE, 2014; NHBLI, 2000). Goal setting is considered to be a key element in helping individuals to regulate their own behavior and has been used in numerous fields including education (e.g., Bandura & Schunk, 1981), sport (e.g., Anshel, Weinberg & Jackson, 1992), health (e.g., Alexy, 1985), social behaviors (e.g., Madera, King & Hebl, 2013), product...
