Consider the source: adolescents and adults similarly follow older adult advice more than peer advice.

ABSTRACT: Individuals learn which of their actions are likely to be rewarded through trial and error. This form of learning is critical for adapting to new situations, which adolescents frequently encounter. Adolescents are also greatly influenced by their peers. The current study tested the extent to which adolescents rely on peer advice to guide their actions. Adolescent and young adult participants completed a probabilistic learning task in which they chose between four pairs of stimuli with different reinforcement probabilities, with one stimulus in each pair more frequently rewarded. Participants received advice about two of these pairs, once from a similarly aged peer and once from an older adult. Crucially, this advice was inaccurate, enabling the dissociation between experience-based and instruction-based learning. Adolescents and adults learned equally well from experience and no age group difference was evident in the overall influence of advice on choices. Surprisingly, when considering the source of advice, there was no evident influence of peer advice on adolescent choices. However, both adolescents and adults were biased toward choosing the stimulus recommended by the older adult. Contrary to conventional wisdom, these data suggest that adolescents may prioritize the advice of older adults over that of peers in certain decision-making contexts.

Project description:ObjectiveTo improve the quality of peer leader training, this study developed a theory-based self-management training program for older adult peer leaders with diabetes and assessed its feasibility.BackgroundCurrent self-management programs are designed mainly to be implemented by healthcare professionals, but healthcare staff may not fully perceive the needs and obstacles of older adults in disease management due to a lack of similar illness experience. To target this problem, peer leaders with successful self-management experiences, similar cultural backgrounds and languages, and related illness experiences are trained to guide and mentor peer patients in self-management programs.Study design and methodsThis study was conducted in two stages. In stage 1, a peer leader training program was developed based on experiential learning theory as the framework and self-regulation theory as the activity design strategy. In stage 2, program feasibility was assessed via participants' feedback toward the training program by three indicators: attendance, future willingness to lead the peer-led self-management program, and leadership skills evaluated by a peer leader training assessment tool.ResultsIn this study, peer leaders demonstrated good leadership skills by expressing active willingness to lead self-management programs in the community. Peer leaders' feedback indicated that the program's training content was helpful in preparing peer leaders to guide older adults in learning self-management skills and in improving the abilities and confidence of peer leaders in mentoring self-management.ConclusionFindings in this study showed that peer leader training can impact the effectiveness and success of self-management in older adults with diabetes. Even in a small-scale study, the impact was evident, which demonstrated the feasibility of the program. More large-scale studies on the effectiveness of various peer leader training programs in diverse disciplines are recommended.Clinical trials registryClinicalTrials.gov Identifier: NCT04298424 (the Peer-Led Self-Management Program).

Project description:To determine prospectively the prevalence and rate of malignancy of multiple bilateral (MB) circumscribed breast masses detected at screening ultrasonography (US) compared with those of other US-depicted masses.This institutional review board-approved, HIPAA-compliant prospective trial included women at elevated risk for breast cancer, who gave written informed consent to participate in a study evaluating cancer detection rates for three rounds of annual supplemental screening US at 21 international sites. After exclusions, 2662 participants and 7473 screening studies were included. Physician-performed US studies were interpreted, with blinding to mammography results. Simple cysts were noted. Breast Imaging Reporting and Data System features of all other findings were recorded, with addition of the descriptor MB similar-appearing circumscribed masses (minimum of three total and at least one in each breast), with details of the largest such mass recorded. Rates of malignancy were determined after biopsy or mammographic and US follow-up at a minimum of 11 months. For this analysis, 490 women (1370 screenings) with prior mastectomy were excluded. Descriptive statistics and exact 95% confidence intervals (CIs) were generated.Of 2172 evaluable participants (6103 screening studies; median age at study entry, 54.0 years; range, 25-91 years), 1454 had unique findings at US. One hundred thirty-five (6.2%) participants had 153 unique MB circumscribed masses, with no malignancies (0% [95% CI: 0%, 2.4%]; 95% CI: 0%, 2.9% for the 127 masses with at least 2 years of follow-up). There were 1319 (60.7%) participants with 2464 non-MB lesions, including 1038 solitary circumscribed masses with a malignancy rate of 0.8% (eight of 1038). Of 836 solitary circumscribed masses with at least 2 years of follow-up, the malignancy rate was 0.4% (three of 836; 95% CI: 0.1%, 1.0%). Of the 135 women with MB circumscribed masses, 82 (60.7%) also had a solitary lesion. Two of these 82 women (2.4%) had cancer.MB similar-appearing circumscribed masses seen at screening US are almost always benign, with no malignancies found among such lesions in this prospective, multicenter experience. These lesions are suitable for diagnostic follow-up in 1 year, with resumption of screening thereafter if they are stable.
