Background: State-of-the-art behavioral weight loss treatment (SBT) can lead to clinically meaningful weight loss, but only 30-60% achieve this goal. Developing adaptive interventions that change based on individual progress could increase the number of people who benefit.Purpose: Conduct a Sequential Multiple Assignment Randomized Trial (SMART) to determine the optimal time to identify SBT suboptimal responders and whether it is better to switch to portion-controlled meals (PCM) or acceptance-based treatment (ABT).Method: The BestFIT trial enrolled 468 adults with obesity who started SBT and were randomized to treatment response assessment at Session 3 (Early TRA) or 7 (Late TRA). Suboptimal responders were re-randomized to PCM or ABT. Responders continued SBT. Primary outcomes were weight change at 6 and 18 months.Results: PCM participants lost more weight at 6 months (-18.4 lbs, 95% CI -20.5, -16.2) than ABT participants (-15.7 lbs, 95% CI: -18.0, -13.4), but this difference was not statistically significant (-2.7 lbs, 95% CI: -5.8, 0.5, p = .09). PCM and ABT participant 18 month weight loss did not differ. Early and Late TRA participants had similar weight losses (p = .96), however, Early TRA PCM participants lost more weight than Late TRA PCM participants (p = .03).Conclusions: Results suggest adaptive intervention sequences that warrant further research (e.g., identify suboptimal responders at Session 3, use PCMs as second-stage treatment). Utilizing the SMART methodology to develop an adaptive weight loss intervention that would outperform gold standard SBT in a randomized controlled trial is an important next step, but may require additional optimization work.Clinical Trial Information: ClinicalTrials.gov identifier; NCT02368002.

Background Individuals receiving behavioral weight loss treatment frequently fail to adhere to prescribed dietary and self-monitoring instructions, resulting in weight loss clinicians often needing to assess and intervene in these important weight control behaviors. A significant obstacle to improving adherence is that clinicians and clients sometimes disagree on the degree to which clients are actually adherent. However, prior research has not examined how clinicians and clients differ in their perceptions of client adherence to weight control behaviors, nor the implications for treatment outcomes. Purpose In the context of a 6-month weight-loss treatment, we examined differences between participants and clinicians when rating adherence to weight control behaviors (dietary self-monitoring; limiting calorie intake) and evaluated the hypothesis that rating one's own adherence more highly than one's clinician would predict less weight loss during treatment. Methods Using clinician and participant-reported measures of self-monitoring and calorie intake adherence, each assessed using a single item with a 7- or 8-point scale, we characterized discrepancies between participant and clinician adherence and examined associations with percent weight change over 6 months using linear mixed-effects models. Results Results indicated that ratings of adherence were higher when reported by participants and supported the hypothesis that participants who provided higher adherence ratings relative to their clinicians lost less weight during treatment (p < 0.001). Conclusions These findings suggest that participants in weight loss treatment frequently appraise their own adherence more highly than their clinicians and that participants who do so to a greater degree tend to lose less weight.

Objective: To examine relationships between parenting styles and practices and child moderate-to-vigorous physical activity (MVPA) and screen time. Methods: Participants were children (6.9 ± 1.8 years) with a body mass index in the 70–95th percentile and their parents (421 dyads). Parent-completed questionnaires assessed parental support for child physical activity (PA), parenting styles and child screen time. Children wore accelerometers to assess MVPA. Results: Parenting style did not predict MVPA, but support for PA did (positive association). The association between support and MVPA, moreover, varied as a function of permissive parenting. For parents high in permissiveness, the association was positive (greater support was related to greater MVPA and therefore protective). For parents low in permissiveness, the association was neutral; support did not matter. Authoritarian and permissive parenting styles were both associated with greater screen time. Conclusions: Parenting practices and styles should be considered jointly, offering implications for tailored interventions. [ABSTRACT FROM AUTHOR]

Although a considerable body of evidence supports telephone quit lines for smoking cessation, much less is known about the effectiveness of proactive Telephone Counseling with smokeless tobacco (ST) users. We conducted a randomized controlled trial comparing Telephone Counseling with the distribution of a self-help manual for ST cessation. We recruited 406 adult ST users throughout the state of Minnesota and randomized them to receive either: (a) a self-help manual (Manual only) or (b) a self-help manual plus proactive telephone-based cessation counseling (Telephone Counseling). The telephone-based treatment included up to four calls in support of quitting, and personalized various cognitive and behavioral strategies that are generally considered effective in tobacco cessation (such as setting a quit date, examining patterns of use, developing stress reduction skills, avoiding known triggers to use). Participants were surveyed by phone at 3 and 6 months to assess both point prevalence and continued abstinence. Prolonged abstinence from all tobacco was 6.8% and 30.9% (p<.001) at 3 months and 9.8% and 30.9% (p<.001) at 6 months in Manual only and Telephone Counseling, respectively. We found older age, lower dependency, and increased readiness predicted quitting success. Proactive telephone-based counseling is an effective strategy for improving cessation rates among ST users. Future research should determine the components contributing to the intervention success. [ABSTRACT FROM AUTHOR]

Background: Six months of loss followed by gradual regain to baseline is descriptive of most weight toss attempts. Purpose: This study sought to identify thoughts and feelings accompany-ing weight loss that might explain the phenomenon. Methods: Thoughts, feelings, and body weight were measured weekly for 6 months in 41 women receiving behavioral treatment for obesity. Results: Overall, the weight loss experience of these women was positive, requiring modest time and effort and being associated with more positive than negative thoughts and experiences. Over lime, however, positive but not negative reactions to the weight loss experience decreased, as did the strength of beliefs that the benefits of weight loss were worth the effort. In addition, we found no relation between the women's perception of effort and weight loss results. Conclusions: Inadequate long-term rewards for behaviors needed for weight control may be an important cause of frequent weight loss failures. [ABSTRACT FROM AUTHOR]
