Previous research has identified reward sensitivity as an important factor that may contribute to the engagement in eating behavior (e.g., binge eating, emotional eating, etc.) and increase obesity risk. In the current study, we conducted a systematic review of the literature to determine the relationships between reward sensitivity, eating behavior, and obesity-related outcomes. The study focused on two commonly used measures of reward sensitivity in the literature: the Sensitivity to Punishment and Sensitivity to Reward Questionnaire (SPSRQ) and the Behavioral Inhibition Scale/Behavioral Activation Scale (BIS/BAS Scale).
We conducted a systematic search to identify studies that analyzed reward sensitivity as a predictor of eating behavior or obesity-related outcomes, and measured reward sensitivity using the SPSRQ or BIS/BAS Scale. The search yielded N=19 total publications included in the review.
Findings indicated that reward sensitivity, primarily measured by summary scores on the SPSRQ or BIS/BAS Scale, were positively associated with a variety of eating behaviors and obesity-related outcomes with small to moderate effect sizes. Findings were most consistent across studies that examined the association between reward sensitivity and eating behavior outcomes (e.g., binge eating, emotional eating) (r values= .08 to .41; p values < .001 to p < .05) and food consumption outcomes (e.g., palatable food intake) (r values = .21 to .40; p < .001 to p values < .05). Findings were less consistent for food craving and BMI outcomes, and revealed these relationships may depend on individual-level factors and/or environment-related factors, (e.g., food cues). A quality evaluation using the Critical Appraisal Tool for Cross-Sectional Studies (AXIS tool) indicated that most studies were rated as moderate to strong quality (84%).
Findings indicate that elevated reward sensitivity may be a risk factor for engagement in eating behaviors that may increase obesity risk.
先前的研究已经确定奖励敏感性是一个重要因素，它可能导致参与进食行为（例如暴食、情绪化进食等），并增加肥胖的风险。在本研究中，我们对文献进行了系统回顾，以确定奖励敏感性、进食行为和肥胖相关结果之间的关系。研究重点关注文献中两种常用的奖励敏感性测量方法：惩罚敏感性和奖励敏感性问卷（SPSRQ）以及行为抑制/行为激活量表（BIS/BAS 量表）。
我们进行了系统搜索，以确定分析奖励敏感性作为进食行为或肥胖相关结果预测因子的研究，并使用 SPSRQ 或 BIS/BAS 量表测量奖励敏感性。搜索共产生了 19 项符合综述要求的出版物。
研究结果表明，奖励敏感性主要通过 SPSRQ 或 BIS/BAS 量表的总分来衡量，与各种进食行为和肥胖相关结果呈正相关，其相关效应大小为小至中等。在研究奖励敏感性与进食行为结果（例如暴食、情绪化进食）（r 值为 0.08 至 0.41；p 值 < 0.001 至 p < 0.05）和食物消耗结果（例如美味食物摄入量）（r 值为 0.21 至 0.40；p 值 < 0.001 至 p 值 < 0.05）的研究中，结果最为一致。在研究奖励敏感性与食物渴望和 BMI 结果的研究中，结果不太一致，表明这些关系可能取决于个体因素和/或环境相关因素（例如食物线索）。使用横断面研究的批判性评价工具（AXIS 工具）进行的质量评估表明，大多数研究的质量被评为中等至强（84%）。
研究结果表明，较高的奖励敏感性可能是参与进食行为的风险因素，而这些行为可能会增加肥胖的风险。
