Using Word Embeddings To Explore The Language Of Depression On Twitter, Sandhya Gopchandani

Graduate College Dissertations and Theses

How do people discuss mental health on social media? Can we train a computer program to recognize differences between discussions of depression and other topics? Can an algorithm predict that someone is depressed from their tweets alone? In this project, we collect tweets referencing “depression” and “depressed” over a seven year period, and train word embeddings to characterize linguistic structures within the corpus. We find that neural word embeddings capture the contextual differences between “depressed” and “healthy” language. We also looked at how context around words may have changed over time to get deeper understanding of contextual shifts in the …

Clinical Evidence Technologies And Patient Care, Marianne D. Burke

Graduate College Dissertations and Theses

ABSTRACT

Clinical evidence technologies (CETs) are information sources derived from medical research literature that may assist health care providers in continued learning, decision-making, and patient care. Examples of CETs include: MEDLINE/PubMed and Cochrane Reviews, research journal literature, print and electronic medical texts, clinical topic summaries, guidelines, and interactive decision tools. Clinicians utilize CETs to find answers to questions that arise during patient care. However, it was unclear if CETs had a measurable impact on provider practice or patient outcomes.

A literature review identified twenty-two articles evaluating CETs’ impact. Study designs included surveys, observational studies, randomized controlled trials and quasi-experimental methods. …

Referral Patterns And Service Provision In Child Protective Services: Child, Caregiver, And Case Predictors, Hannah Mead Holbrook

Graduate College Dissertations and Theses

Child maltreatment, and recurrent maltreatment in particular, occurs at an alarmingly high rate. Frequency of reports to Child Protective Services (CPS) is associated with negative psychological outcomes, and children whose reports are unsubstantiated experience similar risk of behavioral, emotional, and substance use disorders as those whose reports are substantiated. Prior research has demonstrated that children with no CPS reports and children with one CPS report showed no significant differences in rates of maltreatment perpetration or substance use in adulthood, suggesting that prevention efforts after one report may have strong merit in reducing negative outcomes in adulthood. However, patterns and risk …

Predictors Of Psychotherapy Attrition Among Refugees, Emily Robin Pichler

Graduate College Dissertations and Theses

It is estimated that approximately one in five patients will terminate therapy early, before participating in full treatment and obtaining maximum therapeutic benefits. Millions of people are forcibly displaced as refugees each year, and therefore at increased risk for poverty, discrimination, and complex mental health needs, yet no research has yet examined rates or predictors of psychotherapy attrition among refugees. The current study draws upon a sample of refugee clients seeking treatment at a community clinic (N = 196), and a comparison group of 165 non-refugee clients at the same clinic. Logistic regression was employed to (1) compare rates of …
