To compare motivational interviewing (MI) with conventional care regarding the health-related quality-of-life (HRQoL) of adolescents with overweight/obesity.
RCT with parallel design, involving two groups: intervention group (MI group [MIG]) and control group (conventional intervention group [CIG]). The intervention included three 30-minute interviews 3 months apart.
Change in Pediatric Quality of Life Inventory (PedsQL) scores. A mixed repeated-measures analysis of variance was used to assess group versus time interactions.
Eighty-three participants finished the protocol (82% girls). MIG participants showed a significant average increase (+4.7) on the Psychosocial (t[41] = -2.388, p = .022, d = .37) and Emotional Subscales (+5.1) (t[41] = 5.733, p < .001, d = .88). CIG participants showed a significant average decrease on the Psychosocial (-6.1) (t[40] = 5.733, p < .001, d = .90), Emotional (-14.1) (t[40] = 7.249, p < .001, d = 1.13) and Social Subscales (-3.8) (t[40] = 3.782, p = .001, d = .59) and on the Total Score (-4.4) (t[40] = 3.535, p = .001, d = .55) CONCLUSION: MI improved HRQoL among overweight adolescents participating in a weight management program.
MI increases HRQoL and has the potential to benefit weight management programs for adolescents.
比较动机性访谈（MI）与常规护理对超重/肥胖青少年健康相关生活质量（HRQoL）的影响。
采用平行设计的 RCT，包括两组：干预组（MI 组[MIG]）和对照组（常规干预组[CIG]）。干预措施包括三次 30 分钟的访谈，间隔 3 个月。
使用混合重复测量方差分析评估组间与时间的相互作用。
83 名参与者完成了方案（82%为女孩）。MIG 参与者在心理社会（t[41] = -2.388，p =.022，d =.37）和情绪（t[41] = 5.733，p <.001，d =.88）两个分量表上的平均得分显著增加（+4.7）。CIG 参与者在心理社会（-6.1）（t[40] = 5.733，p <.001，d =.90）、情绪（-14.1）（t[40] = 7.249，p <.001，d = 1.13）和社会（-3.8）（t[40] = 3.782，p =.001，d =.59）分量表和总分（-4.4）（t[40] = 3.535，p =.001，d =.55）方面的平均得分显著降低。
MI 改善了参加体重管理计划的超重青少年的 HRQoL。
MI 提高了 HRQoL，有可能有益于青少年的体重管理计划。
