Online Intervention for Transgender/Nonbinary Young Adults' Experiences With Alcohol and Romantic Relationships

Alcoholic drinks per week

Average (mean) number of alcoholic drinks per week over the prior 30 days based on timeline followback, i.e., how many alcoholic drinks a participant recalls having on each specific day.

Depression symptoms

Self-report of depression symptoms in the prior 30 days, as measured by the Patient Health Questionnaire-9 (PHQ-9). The PHQ-9 is a 9-item questionnaire with each item scored from 0 to 3. Scores can range from 0 to 27 (scores of 5-9 are classified as mild depression; 10-14 as moderate depression; 15-19 as moderately severe depression; ≥ 20 as severe depression).

Anxiety symptoms

Self-report of generalized anxiety symptoms in the prior 30 days, as measured by the Generalized Anxiety Disorder-7 (GAD-7). The GAD-7 is a 7-item instrument with each item scored between 0 and 3 where 0=not at all, and 3= nearly every day. Scores can range from 0 to 21 and are interpreted as-- scores 0-4: Minimal Anxiety, scores 5-9: Mild Anxiety, scores 10-14: Moderate Anxiety, and scores greater than 15: Severe Anxiety.

Heavy drinking days

The number of days during the past 30 days when a participant recalls having five or more drinks, based on timeline followback, i.e., how many alcoholic drinks a participant recalls having on each specific day.

Negative alcohol consequences

Self-report of negative alcohol consequences based on the Patient-Reported Outcomes Measurement Information System (PROMIS) Alcohol Negative Consequences Short Form. The PROMIS Alcohol Negative Consequences Short Form is a 7-item instrument with each item scored between 1 and 5 where 1=never and 5=almost always. These items are summed to calculate a raw score between 0 and 7, which is then converted to a T-score that indicates how much someone experiences negative consequences from their alcohol use relative to the United States general population. A T-score of 50 indicates that a person reported the same degree of negative alcohol consequences as the average U.S. adult, scores below 50 indicate fewer negative alcohol consequences than the average U.S. adult, and scores above 50 indicate more negative alcohol consequences than the average U.S. adult.

Intimate Personal Violence (IPV) victimization

Measured with the Sexual and Gender Minority adaptation of the Revised Conflict Tactics Scale-Short Form, a 74-item instrument assessing specific forms of aggression (psychological, physical acts, physical injury, and sexual), as well as nonviolent conflict resolution strategies, within romantic partnerships. Each partner's use of each tactic is assessed separately (perpetration; victimization) Each item is scored from 0=Never to 6=More than 20 times. The scoring range varies by tactic, with scores of 0 representing the absence of that tactic in the past month, and higher scores indicating a greater frequency of that tactic in the past month.

Relationship satisfaction

Measured with the Couple Satisfaction Index - 4, a four-item instrument assessing overall satisfaction in a romantic relationship. The response scales vary by item (0=Not at all, 5=Completely for one item; 0=Extremely unhappy, 6=Perfect for two items; and 0=Not at all true, 5=Completely true for one item). Scores range from 0 to 21, with higher scores indicating higher levels of relationship satisfaction and scores below 13.5 indicating marked dissatisfaction.

Cannabis misuse

Measured by the Cannabis Use Disorder Identification Test-Revised (CUDIT-R), an 8-item instrument assessing problematic or harmful cannabis use. The first 7 items have response options ranging from 0=Never to 4=Daily/almost daily, and the final item has response options ranging from 0=Never to 4=Yes, during the past 6 months. Scores have a range of 0 to 32, with scores of 8 or more indicating hazardous cannabis use and scores of 12 or more indicating possible cannabis use disorder.

Past week cannabis use

Measured with the question "How many days of the past week did you use cannabis?" with a definition of cannabis and response options ranging from "1 day" to "7 days."
