Preliminary studies suggested that headache disorders are more common in patients with joint hypermobility syndrome (JHS). The objectives of this study were to determine if the prevalence, frequency, and disability of migraine differ between female patients with JHS and a control population. Twenty-eight patients with JHS and 232 controls participated in the case-cohort study. Participants underwent a structured verbal interview and were assigned a diagnosis of migraine based on criteria of the International Classification of Headache Disorders, 2nd Edition. The primary outcome measures were the prevalence, frequency, and headache-related disability of migraine. Logistic regression was used for the prevalence analysis and Poisson regression for the frequency and disability analyses. Results indicated that the prevalence of migraine was 75% in JHS patients and 43% in controls. The adjusted odds ratio for the prevalence of migraine was 3.19 (95% CI 1.24, 8.21] in JHS patients. The rate ratios for migraine frequency and headache-related disability were 1.67 (95% CI 1.01, 2.76) and 2.99 (95% CI 1.66, 5.38), respectively, for JHS patients. Our study suggests that JHS is a clinical disorder strongly associated with an increased prevalence, frequency, and disability of migraine in females.

Supervision is critical to the training of genetic counselors. Limited research exists on the influence of supervision training and experience on the development of genetic counseling supervisors. The purpose of this study was to investigate the impact of supervision training in addition to supervisory and clinical experience on supervisory identity development, and the perceived confidence and competence supervisors have in their own supervisory skills. In addition, we explored genetic counselors' (N = 291) interest in and barriers to training as well as perspectives on requirements for supervisors. Results indicated clinical experience, supervision experience, and formal supervision training are positively associated with genetic counselors' supervisory identity development as measured by the Psychotherapy Supervisory Development Scale (PSDS) (p < 0.05). Despite a moderate correlation between supervision experience and formal training (ρ = 0.42, p < 0.001), both had independent effects on PSDS scores (p < 0.04). A majority of genetic counselors were interested in receiving supervision training but noted lack of available training as a barrier. The majority of participants indicated that supervisors should be certified as genetic counselors, but there was no consensus on training requirements. Development of additional supervision training opportunities for genetic counselors should be considered.

This study describes the development of a self-efficacy scale that is specific to genetic counseling and based both on Bandura's self-efficacy theory (2006) and the Accreditation Council for Genetic Counseling practice-based competencies (2013). The phase 1 validation compared genetic counseling students (n = 20) and genetic counselors (n = 18). Nine items were removed from the scale at this point for lack of discrimination or redundancy. The phase 2 validation included a larger cohort of genetic counseling students (n = 168). Factor analysis identified six factors accounting for 58% of the total variance. Cronbach's alpha as well as the inter-item correlations and item-total correlations of both the full scale items and underlying factors indicated that the items and factors of the scale are sufficiently related, but not redundant. The newly developed Genetic Counseling Self-Efficacy Scale (GCSES) has the potential to be used as an outcome measure in research related to training or professional development of genetic counselors as well as for a training tool.
