Background And Aims: Advanced colorectal polyps (adenoma or sessile serrated polyp ≥ 1 cm, adenoma with villous features, adenoma with high-grade dysplasia, or any sessile serrated polyps with dysplasia) are associated with an increased risk of future advanced colorectal neoplasia and confer an increased risk of advanced neoplasia to first-degree family members. Professional societies therefore recommend more intensive surveillance of these polyps and earlier screening for first-degree relatives. The aim of this study was to assess knowledge of personal and familial risk and recommendations among patients with advanced colorectal polyps and identify predictors of knowledge.

Background: Inflammatory bowel diseases (IBD) often begins early in life. Adolescents and young adults (AYA) with IBD have to acquire behaviors that support self-care, effective healthcare decision-making, and self-advocacy to successfully transition from pediatric to adult health care. Despite the importance of this critical time period, limited empirical study of factors associated with transition readiness in AYA exists.

Low adherence is a pervasive issue among youth with inflammatory bowel diseases (IBD), yet our understanding of perceived adherence barriers is hampered by a lack of validated instruments. This study sought to address this by evaluating the reliability and predictive validity of the Beliefs About Medication Scale (BAMS) among youth with IBD. Seventy-six youth (ages 11-18) with IBD who were prescribed a daily oral IBD medication completed baseline ratings of perceived adherence barriers via the BAMS.

Background: Although adequate disease-related knowledge is recognized as an important component of transition readiness, little empirical attention has been directed toward understanding the levels of disease knowledge of adolescents and young adults (AYAs) with inflammatory bowel diseases (IBDs) or factors associated with higher levels of knowledge. This study described disease knowledge in a sample of AYAs with IBDs and examined individual, family, and patient-provider relationship factors associated with higher knowledge.

Methods: Seventy-five AYAs (ages 16-20) and their parents participated.

Background: Medication nonadherence is associated with higher disease activity, greater health care utilization, and lower health-related quality of life in pediatric inflammatory bowel diseases (IBD). Problem solving skills training (PSST) is a useful tool to improve adherence in patients with chronic diseases but has not been fully investigated in IBD. This study assessed feasibility, acceptability, and preliminary efficacy of PSST in pediatric IBD.

Objective: To examine longitudinal trajectories of oral thiopurine adherence over a 180-day interval in a sample of youth with inflammatory bowel disease (IBD) and to identify the role of disease activity, length of time since diagnosis, and regimen complexity in predicting adherence trajectory class membership.

Method: Participants included 96 adolescents (M age = 14.32 years) with IBD.

Objective: To examine associations between disease-related, individual, and contextual risk factors and health-related quality of life (HRQoL) in a sample of youth with inflammatory bowel disease using a cumulative risk model framework.

Methods: Participants were 50 youth (58% male; M age = 15 years). Youth and parents completed measures of HRQoL, psychological functioning, and family functioning.
