Background: Contraceptive care is a key element of reproductive health, yet only 12%-30% of women report being able to access and receive the information they need to make these complex, personal health care decisions. Current guidelines recommend implementing shared decision-making approaches; and tools such as patient decision aid (PtDA) applications have been proposed to improve patients' access to information, contraceptive knowledge, decisional conflict, and engagement in decision-making and contraception use. To inform the design of meaningful, effective, elegant, and feasible PtDA applications, studies are needed of all users' current experiences, needs, and barriers.

Background: Nearly half of intimate partner violence (IPV) survivors experience their first abusive relationship at college age (18-24 years). Most often they disclose the violence to friends. Existing college campus "bystander" interventions training peers to safely intervene have been effective in sexual assault prevention; similar interventions have rarely been tested for IPV.

The objective of this study was to examine differences in change over time in health and safety outcomes among female college students randomized to myPlan, a tailored safety planning app, or usual web-based safety planning resources. Three hundred forty-six women (175 intervention, 171 control) from 41 colleges/universities in Oregon and Maryland completed surveys at baseline, 6- and 12-months from July 2015 to October 2017. Generalized estimating equations were used to test group differences across time.

Objective: This study piloted a patient education and decision aid tool about prescription pain relievers to determine potential impact on: comfort receiving an opioid prescription; knowledge about opioids; decisional conflict about whether to take an opioid; and shared decision making with the prescribing physician.

Methods: Patients with acute pain were recruited from two emergency departments (ED), and randomized to complete the tool (N = 65) or a time-matched control (N = 59) on a tablet. Data collection involved: a baseline survey; a post-test immediately following the assigned program; a discharge survey after seeing the physician; and a 6-week follow-up survey.

Introduction: A low-vision assessment (LVA) is critical in developing a vision rehabilitation plan. A remotely delivered LVA that replicates a standard in-clinic assessment may bridge the gap for patients not accessing care due to the limited quantity and distribution of low-vision providers. Within an LVA, an accurate and consistent assessment of refraction error is an essential component.

Introduction: A low-vision assessment (LVA) is central to developing a vision rehabilitation plan. However, access to LVAs is often limited by the quantity and geographic distribution of low-vision providers, as well as patient-centred transportation challenges. A tablet-based LVA tool kit, delivered virtually, has the potential to overcome many of these barriers.

We explored decisional conflict as measured with the 16-item Decisional Conflict Scale (DCS) and how it varies across clinical situations, decision types, and exposure to decision support interventions (DESIs). An exhaustive scoping review was conducted using backward citation searches and keyword searches. Eligible studies were published between 1995 and March 2015, used an original experimental/observational research design, concerned a health-related decision, and provided DCS data.

The Decisional Conflict Scale (DCS) measures 5 dimensions of decision making (feeling: uncertain, uninformed, unclear about values, unsupported; ineffective decision making). We examined the use of the DCS over its initial 20 years (1995 to 2015). We conducted a scoping review with backward citation search in Google Analytics/Web of Science/PubMed, followed by keyword searches in Cochrane Library, PubMed, Ovid MEDLINE, EMBASE, CINAHL, AMED, PsycINFO, PRO-Quest, and Web of Science.
