“…Several studies examined the use of MI as an adjunctive to standard treatments, with no differences found between MI-enhanced FBT to standard FBT (Saelens, Lozano, & Scholz, 2013) or social skills training (Walpole, Dettmer, Morrongiello, McCrindle, & Hamilton, 2013), improved vegetable intake compared to standard Women, Infants, and Children nutritional counseling (Ogu et al, 2014), and improved physical activity outcomes at 6-month followup compared to a standard cognitive-behaviorally based weight loss program (Gourlan, Sarrazin, & Trouilloud, 2013). These results suggest that MI may be a viable addition to well-established treatments and additional research is needed and warranted.…”

Childhood obesity is associated with increased medical and psychosocial consequences and mortality and effective interventions are urgently needed. Effective interventions are urgently needed. This article reviews the evidence for psychological treatments of overweight and obesity in child and adolescent populations. Studies were identified through searches of online databases and reference sections of relevant review articles and metaanalyses. Treatment efficacy was assessed using established criteria, and treatments were categorized as well-established, probably efficacious, possibly efficacious, experimental, or of questionable efficacy. Well-established treatments included family-based behavioral treatment (FBT) and Parent-Only Behavioral Treatment for children. Possibly efficacious treatments include Parent-Only Behavioral Treatment for adolescents, FBT-Guided SelfHelp for children, and Behavioral Weight Loss treatment with family involvement for toddlers, children, and adolescents. Appetite awareness training and regulation of cues treatments are considered experimental. No treatments are considered probably efficacious, or of questionable efficacy. All treatments considered efficacious are multicomponent interventions that include dietary and physical activity modifications and utilize behavioral strategies. Treatment is optimized if family members are specifically targeted in treatment. Research supports the use of multicomponent lifestyle interventions, with FBT and Parent-Only Behavioral Treatment being the most widely supported treatment types. Additional research is needed to test a stepped care model for treatment and to establish the ideal dosage (i.e., number and length of sessions), duration, and intensity of treatments for long-term sustainability of healthy weight management. To improve access to care, the optimal methods to enhance the scalability and implementability of treatments into community and clinical settings need to be established.

“…23 Although meta-analytical differences in effect sizes favor parental involvement, no existing RCT studies compare .2 of the 3 target groups (eg, MI, MI + PI, control) in the same trial experimentally. 23,[27][28][29] The goal of the present RCT was to evaluate the effectiveness of an MI weight loss intervention for obese adolescents including parental involvement (MI + PI) versus MI without parental involvement (MI only) and a passive control group over a period of 12 months. We hypothesized that MI + PI would be effective in changing BMI and other relevant outcomes compared with a control condition.…”

BACKGROUND AND OBJECTIVE: Motivational interviewing (MI) has been shown to be an effective strategy for targeting obesity in adolescents, and parental involvement is associated with increased effectiveness. The aim of this study was to evaluate and compare the role of parental involvement in MI interventions for obese adolescents.METHODS: A total of 357 Iranian adolescents (aged 14-18 years) were randomized to receive an MI intervention or an MI intervention with parental involvement (MI + PI) or assessments only (passive control). Data regarding anthropometric, biochemical, psychosocial, and behavioral measures were collected at baseline and 12 months later. A series of intention-totreat, 2-way repeated-measures analysis of covariance were performed to examine group differences in change in outcomes measures over the 12-month follow-up period.RESULTS: Results revealed significant effects on most of the outcome parameters for MI + PI (eg, mean 6 SD BMI z score: 2.58 6 0.61) compared with the passive control group (2.76 6 0.70; post hoc test, P = .02), as well as an additional superiority of MI + PI compared with MI only (2.81 6 0.76; post hoc test, P = .05). This pattern was also shown for most of the anthropometric, biochemical, psychometric, and behavioral outcome variables.CONCLUSIONS: MI with parental involvement is an effective strategy in changing obesity-related outcomes and has additional effects beyond MI with adolescents only. These findings might be important when administering MI interventions in school settings. WHAT'S KNOWN ON THIS SUBJECT:Motivational interviewing (MI) has been found to increase the effectiveness of weight loss programs in obese children and adolescents. Although parental involvement seems to be linked to its effectiveness, strong conclusions cannot be drawn. WHAT THIS STUDY ADDS:The present study found that MI with parental involvement is an effective strategy in changing obesity-related outcomes and has additional effects beyond MI with adolescents only. These findings are important when administering MI interventions in school settings.

“…The US Preventive Services Task Force recommends screening children aged $6 years for obesity and referring to behavioral interventions. The task force found that effective comprehensive weight-management programs incorporated counseling and other interventions that targeted diet and PA. 20 Despite the strength of the recommendations in guidelines, 15,20 many studies found small or no impact of motivational interviews (MIs) on BMI on overweight [21][22][23][24][25][26][27] or on obese children. [28][29][30] Therefore, it is still necessary to test the effectiveness of the interventions in any context, when possible by using randomized controlled trials.…”

WHAT'S KNOWN ON THIS SUBJECT: Obesity and overweight can seriously affect health outcomes. Many obesity prevention interventions have been proposed, but few have been effective. Motivational interviewing in primary care seems promising, but results in BMI control are controversial and require further investigation.WHAT THIS STUDY ADDS: This is the first study to demonstrate the effectiveness of pediatrician-led motivational interviewing for BMI control in overweight children aged 4 to 7 years. Nevertheless, no effect was observed in boys or when the mother' s education level was low.abstract OBJECTIVE: The aim of this study was to evaluate the effect of family pediatrician-led motivational interviews (MIs) on BMI of overweight (85th $BMI percentile $95th) children aged 4 to 7 years. METHODS:All the family pediatricians working in Reggio Emilia Province (Italy) were invited to participate in the study; 95% accepted. Specific training was provided. Parents were asked to participate in the trial if they recognized their child as overweight. Children were individually randomly assigned to MIs or usual care. All children were invited for a baseline and a 12-month visit to assess BMI and lifestyle behaviors. The usual care group received an information leaflet, and the intervention group received 5 MI family meetings. The primary outcome was the individual variation of BMI, assessed by pediatricians unblinded to treatment groups. RESULTS:Of 419 eligible families, 372 (89%) participated; 187 children were randomized to MIs and 185 to the usual care group. Ninety-five percent of the children attended the 12-month visit. The average BMI increased by 0.49 and 0.79 during the intervention in the MI and control groups, respectively (difference: -0.30; P = .007). MI had no effect in boys or in children whose mothers had a low educational level. Positive changes in parent-reported lifestyle behaviors occurred more frequently in the MI group than in the control group.
