摘要
希望是一种由代理（内在驱动力）、途径（感知到的外部手段）和目标（未来目标）组成的动机状态，可以预测减肥，但证据有限。本研究考察了希望及其子量表（代理、途径、目标）作为行为治疗中体重减轻的预测因子。方法体重指数(BMI)≥27的成人（n = 107）参加为期6个月的减肥计划，随访12个月。使用成人希望量表-修订版（HSR-2）在基线时评估希望及其分量表。计算治疗后（n = 70）和随访（n = 61）的体重减轻百分比（%WL）。协变量包括积极影响、感恩、乐观、年龄、性别、教育程度、身体质量指数和不良的童年经历。线性回归检验了治疗后和随访时HSR-2总量表和子量表与%WL之间的关系，并调整了协变量。使用多重输入数据进行完整的病例和意向治疗分析。结果完整病例分析显示，HSR-2总分可预测更高的%WL (β =。16、p =。001后处理;β =。29, p =。003后续)。这种效应是由通路(β =。63, p =。001后处理;β = 1.02, p <；001随访)，机构和目标与%WL无关（ps≥.353）。感恩与%WL负相关（β =−）。82, p =。001后处理;β =−。78, p =。020后续)。意向治疗样本中，HSR-2总倾向于随访%WL (β =。14, p = .062)；在两个时间点预测的通路(β =。32、p =。047后处理;β =。59, p =。001后续)。结论高通路思维是希望的一个组成部分，可预测临床显著的体重减轻和体重维持。较低的感激之情可能预示着体重下降（在完成者中），这表明对当前状态的不满，加上对通往更美好未来的道路的信念，推动了更大的体重下降。
Hope and behavioural weight loss: Pathways lead to greater weight loss than agency or goals
Background
Hope is a motivational state comprised of agency (internal drive), pathways (perceived external means), and goals (future targets) that may predict weight loss, but evidence is limited. This study examined hope and its subscales (agency, pathways, goals) as predictors of weight loss in a behavioural treatment.
Method
Adults (n = 107) with body mass index (BMI) ≥ 27 participated in a 6-month weight loss program with 12-month follow-up. Hope and its subscales were assessed at baseline using the Adult Hope Scale-Revised (HSR-2). Percent weight lost (%WL) was calculated for post-treatment (n = 70) and follow-up (n = 61). Covariates included positive affect, gratitude, optimism, age, sex, education, BMI, and adverse childhood experiences. Linear regressions tested the relationship between HSR-2 total and subscales with %WL at post-treatment and follow-up, adjusting for covariates. Complete case and intention-to-treat analyses with multiply imputed data were conducted.
Results
Complete case analyses showed HSR-2 total scores predicted greater %WL (β = .16, p = .001 post-treatment; β = .29, p = .003 follow-up). This effect was driven by pathways (β = .63, p = .001 post-treatment; β = 1.02, p < .001 follow-up), with agency and goals unrelated to %WL (ps ≥ .353). Gratitude inversely related to %WL (β = −.82, p = .001 post-treatment; β = −.78, p = .020 follow-up). Among the intention-to-treat sample, HSR-2 total trended towards follow-up %WL (β = .14, p = .062); pathways predicted at both timepoints (β = .32, p = .047 post-treatment; β = .59, p = .001 follow-up).
Conclusion
Higher pathways thinking, a component of hope, predicted clinically significant weight loss and weight maintenance. Lower gratitude may predict weight loss (among completers), suggesting dissatisfaction with one's current state, combined with a belief in pathways to a better future, drove greater weight loss.
期刊介绍：
The focus of the British Journal of Health Psychology is to publish original research on various aspects of psychology that are related to health, health-related behavior, and illness throughout a person's life. The journal specifically seeks articles that are based on health psychology theory or discuss theoretical matters within the field.
