This study investigated whether women's initial reasons (health, appearance to others, or appearance to self) for wanting to lose weight influenced their weight change over a 30-month web-based intervention. Multilevel modeling with 1416 observations revealed that only appearance in relation to one's self was a significant (negative) predictor. Women highly motivated to lose weight to improve their appearance in relation to themselves gained weight at 30 months, whereas those not motivated for this reason achieved clinically significant weight loss. Results suggest examining participants' initial reasons for weight loss as an important component of intervention failure or success.
本研究调查了女性想要减肥的初始原因（健康、在他人眼中的外表或自我认知中的外表）是否会影响她们在为期30个月的网络干预中的体重变化。对1416个观察对象进行的多水平建模显示，只有自我认知中的外表是一个显著的（负面）预测因素。出于改善自我认知中的外表而有强烈减肥动机的女性在30个月时体重增加，而那些并非出于此原因而有减肥动机的女性则实现了临床上显著的体重减轻。结果表明，将参与者减肥的初始原因作为干预成败的一个重要组成部分进行考察。
