Profiling “Success”: Demographic and Personality Predictors of Effective Peer Leaders in a Diabetes Self-management Intervention

Published:January 17, 2022DOI:https://doi.org/10.1016/j.jcjd.2022.01.001

      Abstract

      Background

      The sociodemographic and personality profiles of effective peer leaders in the context of diabetes self-management interventions are poorly understood. In this study, we explored the demographic and personality characteristics of peer leaders participating in a 12-month, telephone-based type 2 diabetes self-management intervention.

      Methods

      We used a sequential explanatory mixed-methods research design and recruited 52 peer leaders. Thirty-seven peer leaders had at least 1 participant complete both the baseline and the 12-month assessments. Eligible peer leader candidates were English-speaking adults (≥21 years of age) with diabetes and a self-reported glycated hemoglobin (A1C) level of ≤8% who had access to a phone and transportation and were willing to attend a 30-hour training program. Peer leaders completed a self-report survey assessing sociodemographic characteristics and a Mini-International Personality Item Pool scale measuring the “Big 5” personality traits. After the intervention, 17 peer leaders participated in semistructured interviews on their program experience. We categorized peer leaders as effective if their participants sustained or improved their A1C and diabetes distress (DD) scores from baseline to 12 months, and as ineffective if their participants worsened on any of these parameters.

      Results

      Our cohort scored highest on agreeableness and lowest on neuroticism. Twenty peer leaders were considered effective, most of whom were male, married, employed and educated. They also had significantly lower mean DD levels (p=0.02) and a higher extroversion score (p=0.03) at baseline.

      Conclusions

      Extroversion emerged as the best personality predictor of peer leader effectiveness. These results, in combination with interview responses, were used to produce a peer leader selection model.

      Résumé

      Introduction

      On connaît mal les profils sociodémographiques et de personnalité des pairs animateurs efficaces dans le contexte des interventions en matière de prise en charge autonome du diabète. Dans la présente étude, nous avons exploré les caractéristiques démographiques et de personnalité des pairs animateurs qui avaient participé à une intervention téléphonique en matière de prise en charge autonome du diabète de type 2 d’une durée de 12 mois.

      Méthodes

      Nous avons utilisé un devis de recherche séquentiel explicatif par méthodes mixtes et recruté 52 pairs animateurs. Trente-sept pairs animateurs ont au moins eu 1 participant qui avait rempli l’évaluation initiale et l’évaluation après 12 mois. Les pairs animateurs qui étaient des candidats admissibles étaient des adultes anglophones (≥ 21 ans) atteints de diabète et avaient des concentrations d’hémoglobine glyquée (A1c) autodéclarées de ≤ 8 %, avaient accès à un téléphone et à un moyen de transport, et étaient prêts à participer à un programme de formation de 30 heures. Les pairs animateurs ont rempli une enquête d’auto-évaluation des caractéristiques sociodémographiques et une échelle du Mini-International Personality Item Pool (Mini-IPIP) qui permet de mesurer les traits de personnalité selon le modèle du « Big Five ». Après l’intervention, 17 pairs animateurs ont participé aux entretiens semi-structurés sur leur expérience du programme. Nous avons considéré les pairs animateurs efficaces si leurs participants avaient maintenu ou amélioré leur A1c et les scores de détresse liée au diabète (DD) du début à 12 mois, et inefficaces si leurs participants avaient montré une détérioration de l’un de ces paramètres.

      Résultats

      Notre cohorte a eu le score le plus élevé pour l’agréabilité et le score le plus bas pour le névrosisme. Vingt pairs animateurs ont été considérés comme efficaces. La plupart d’entre eux étaient des hommes, étaient mariés, avaient un emploi et étaient instruits. Ils avaient aussi des degrés moyens de DD significativement plus bas (p = 0,02) et un score d’extroversion plus élevé (p = 0,03) au début.

      Conclusions

      L’extroversion représentait le trait de personnalité le plus prédictif de l’efficacité des pairs animateurs. Ces résultats, combinés aux réponses des entretiens, ont été utilisés pour produire le modèle de sélection des pairs animateurs.
