Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Trauma Expressive Writing; In the trauma condition, we ask participants to write about a traumatic experience, prompting them to write their very deepest thoughts and feelings about the most traumatic experience of their entire life or an extremely important stressful, upsetting, or emotional issue that has affected them.	Behavioral: Trauma Expressive Writing; Participants assigned to the trauma condition will write about an experience of trauma for 15 to 20 minutes per day across five consecutive days.
Experimental: Stigma Expressive Writing; In the stigma condition, we ask participants to write about an experience of stigma, prompting them to write about their very deepest thoughts and feelings about the most difficult or painful experience of stigma or bias (e.g., prejudice, bullying, rejection, discrimination) based on one or more of their identities (e.g., race/ethnicity, gender identity, sexual identity, religion) that they have faced.	Behavioral: Stigma Expressive Writing; Participants assigned to the stigma condition will write about an experience of stigma or bias for 15 to 20 minutes per day across five consecutive days.
Placebo Comparator: Control; In the control condition, we ask participants to write about their day, prompting them to write about what they did yesterday from the time they got up until the time they went to bed.	Behavioral: Control; Participants assigned to the control condition will write about their days for 15 to 20 minutes per day across five consecutive days. This control condition is standard across many expressive writing studies.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in PTSD symptom severity	Posttraumatic stress disorder (PTSD) symptoms will be measured with the Psychometric Properties of the Posttraumatic Diagnostic Scale for DSM-5 (PDS-5). The PDS-5 is a 24-item self-report measure designed to assess the severity of DSM-5 PTSD symptoms. The 24-item scale comprises a checklist of traumatic event types the individual has experienced, identification of the most distressing traumatic event, and an assessment of PTSD symptoms. The assessment of PTSD symptoms yields a total score and three subscales (re-experiencing, avoidance, and arousal), and a cutoff score of 28 or higher indicates a probable PTSD diagnosis. Items are scored 1 = once a week or less/a little to 4 = 6 or more times a week/severe. At baseline and 3-month follow-up assessments, participants will complete the PDS-5 in reference to the past month. At the one-week follow-up assessment, participants will complete the PDS-5 in reference to the past week.	Baseline (Pre-intervention), Immediate Post-intervention (1 week post first treatment session), and Three-month Follow-up (3 months post first treatment session)
Change in hazardous drinking levels	The Alcohol Use Disorders Identification Test (AUDIT) will be used to measure hazardous drinking levels. The AUDIT is a 10-item screening measure of problematic alcohol use with individual items ranging from 0 to 4. Scores of 8 and higher are thought to reflect hazardous alcohol use. At baseline and 3-month follow-up assessments, participants will complete the AUDIT in reference to the past month.	Baseline (Pre-intervention) and Three-month Follow-up (3 months post first treatment session)
Change in drinking quantity	To assess drinking quantity in the past week, the investigators will ask participants one question that assesses retrospective estimates for number of drinks consumed on average (in a typical week). The investigators will assess change in the total number of drinks consumed on a typical week in the past month from baseline to total number of drinks consumed in the past week at one-week follow-up and from baseline to total number of drinks consumed in a typical week in the past month at 3-months follow-up assessment. At baseline and 3-month follow-up assessments, participants will complete the hazardous drinking quantity question in reference to a typical week during the past month. At the one-week follow-up assessment, participants will complete the hazardous drinking quantity question in reference to the past week.	Baseline (Pre-intervention), Immediate Post-intervention (1 week post first treatment session), and Three-month Follow-up (3 months post first treatment session)
Change in heavy drinking frequency	The investigators will assess the number of heavy drinking days (days where participants assigned female or intersex at birth consume ≥4 standard drinks and participants assigned male at birth consume ≥5 standard drinks). Response options range from 0 = never to 4 = almost every day where higher scores represent greater heavy drinking frequency. The investigators will assess change in frequency of heavy drinking days in the past month from baseline to frequency of heavy drinking days in the past week at one-week follow-up and from baseline to frequency of heavy drinking days in the past month at 3-months follow-up. At baseline and 3-month follow-up assessments, participants will report frequency of heavy drinking days over the past month. At the one-week follow-up assessment, participants will report frequency of heavy drinking days over the past week.	Baseline (Pre-intervention), Immediate Post-intervention (1 week post first treatment session), and Three-month Follow-up (3 months post first treatment session)

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in trauma centrality.	Trauma centrality will be measured with the Centrality of Events Scale (CSE), which assesses to what degree an event is integrated into an individual's life story and identity. The 20-item questionnaire represents three factors of which the memory of the event has become an (a) reference point for everyday inferences, (b) a core part of personal identity, and (c) a turning point in the life story. Items are rated on a scale from 1 (totally disagree) to 5 (totally agree), and summed to yield a total score.	Baseline (Pre-intervention), Immediate Post-intervention (1 week post first treatment session), and Three-month Follow-up (3 months post first treatment session)
Change in coping.	Coping will be measured using the Brief COPE, a 28-item measure that assesses coping strategies during stress. The Brief COPE consists of 14 subscales with two items per subscale. The investigators will use eight items across four subscales: self-distraction, denial, behavioral disengagement, and self-blame. Respondents rate items using a four-point Likert scale ranging from 1 ("I haven't been doing this at all") to 4 ("I've been doing this a lot"). Greater scores indicate greater use of self-distraction, denial, behavioral disengagement, and self-blame to cope with stress.	Baseline (Pre-intervention), Immediate Post-intervention (1 week post first treatment session), and Three-month Follow-up (3 months post first treatment session)
Change in sexual minority identity-related experiences	Sexual minority identity-related experiences will be assessed with the Lesbian, Gay, Bisexual Identity Scale. This scale contains 27 items and assesses concealment, internalized stigma, and anticipated stigma, among other identity-related constructs. Responses range from 1 (Disagree strongly) to 6 (Agree strongly). Subscale scores are computed by reverse-scoring items as needed and averaging subscale item ratings. Subscale composition is as follows: Acceptance Concerns (5, 9, 16), Concealment Motivation (1, 4, 19), Identity Uncertainty (3, 8, 14, 22), Internalized Homonegativity (2, 20, 27), Difficult Process (12, 17, 23), Identity Superiority (7, 10, 18), Identity Affirmation (6, 13, 26), and Identity Centrality (11, 15, 21, 24, 25).	Baseline (Pre-intervention), Immediate Post-intervention (1 week post first treatment session), and Three-month Follow-up (3 months post first treatment session)
Change in perceived stress.	Perceived stress will be measured with the Ten-Item Perceived Stress Scale (PSS-10), a 10-item self-reporting measure to assess the level of stress experienced by the respondents. Items are scored on a five-point Likert scale, from 0 (never) to 4 (very often). Greater scores indicate greater perceived stress. At baseline and 3-month follow-up assessments, participants will complete the PSS-10 in reference to the past month. At the one-week follow-up assessment, participants will complete the PSS-10 in reference to the past week.	Baseline (Pre-intervention), Immediate Post-intervention (1 week post first treatment session), and Three-month Follow-up (3 months post first treatment session)
Change in depression and anxiety symptoms.	Depression and anxiety symptoms will be assessed using the Brief Symptom Inventory (BSI). The BSI uses 18 items across 2 subscales to capture the extent to which an individual has been distressed by various symptoms of depression and anxiety over the past week (e.g., "Nervousness or shakiness inside" for the anxiety subscale and "Feeling hopeless about the future" for the depression subscale). Possible response options range from 0 (Not at all) to 4 (Extremely). Greater scores indicate greater depression and anxiety symptom severity. At baseline, 1-week, and 3-month follow-up assessments, participants will complete the depression and anxiety subscales in reference to the past week.	Baseline (Pre-intervention), Immediate Post-intervention (1 week post first treatment session), and Three-month Follow-up (3 months post first treatment session)
Change in emotion regulation.	Emotion regulation will be assessed with the Difficulties in Emotion Regulation Scale (DERS). The Difficulties in Emotion Regulation Scale contains 36 items that capture the extent to which an individual generally has trouble regulating their emotions. The investigators will use the distress tolerance and ability to tolerate negative emotions subscales. Possible responses range from 1 (Almost never; 0-10% of the time) to 5 (Almost always; 91-100% of the time). Greater total scores indicate greater difficulties with emotion regulation (i.e., emotion dysregulation).	Baseline (Pre-intervention), Immediate Post-intervention (1 week post first treatment session), and Three-month Follow-up (3 months post first treatment session)
Change in impulsivity.	Impulsivity will be measured with the Short UPPS-P, a 20-item, self-report questionnaire that measures five dimensions of impulsive behavior (negative urgency, lack of premeditation, lack of perseveration, sensation seeking, and positive urgency). Each item is rated on a 4-point scale, from Agree strongly (1) to Disagree strongly (4). The investigators will use the negative urgency subscale from the UPPS-P. Items are reverse scored such that higher scores indicate greater negative urgency (i.e., impulsivity).	Baseline (Pre-intervention) and Three-month Follow-up (3 months post first treatment session)
Change in self-efficacy.	Self-efficacy will be measured by the Generalized Self-Efficacy Scale (GSES). The GSES is a measure of general self-efficacy. It consists of 10 items. Respondents rate each item on a 1 (not true at all) to 4 (exactly true) scale. Higher scores represent greater self-efficacy.	Baseline (Pre-intervention) and Three-month Follow-up (3 months post first treatment session)
Change in attachment style.	Attachment style will be measured using the Experiences in Close Relationships - Short form (ECR- SF). The investigators will use the 6-item anxiety subscale and 6-item avoidance subscale. The ECR uses a 6-point scale to assess both anxious attachment and avoidant attachment. Response options range from 1 = strongly disagree to 6 = strongly agree where higher scores represent greater anxiety and avoidant attachment styles.	Baseline (Pre-intervention) and Three-month Follow-up (3 months post first treatment session)
Change in self-compassion.	Self-compassion will be measured with the Self-Compassion Scale (SCS), a 26-item self-report measure of the degree to which individuals exhibit a kind and accepting attitude toward themselves. The investigators will use the following subscales of the SCS: self-kindness, common humanity, and mindfulness. Responses are on a Likert-type scale from 1 = almost never to 5 = almost always, with higher scores indicating greater self-compassion.	Baseline (Pre-intervention) and Three-month Follow-up (3 months post first treatment session)
Change in suicidality.	Suicidality will be measured with the SBQ-R. Suicide ideation/behavior will be assessed using Item 1 of the SBQ-R. The original SBQ-R consists of four items but only the aforementioned item was used in the current study due to space constraints. However, Item 1 of the SBQ-R has been recommended for screening purposes and has repeatedly been used in clinical and non-clinical samples. Response options range from 0 = Never to 5 = I have attempted to kill myself, and really hoped to die. At baseline and 3-month follow-up assessments, participants will complete the SBQ-R in reference to the past 3 months.	Baseline (Pre-intervention) and Three-month Follow-up (3 months post first treatment session)
Change in hope.	Hope was measured with a hope scale - a single question. Participants will rate their answers on a visual analog scale from 1 ("not at all hopeful") to 10 ("very hopeful"). Higher scores represent greater hope.	Baseline (Pre-intervention) and Three-month Follow-up (3 months post first treatment session)
Change in substance use.	Substance use will be assessed using the Alcohol, Smoking, and Substance Involvement Screening Test (ASSIST), a screening measure of severity of involvement using alcohol, cannabis, cocaine, prescription stimulants, amphetamine-type stimulants, sedatives and sleeping pills, hallucinogens, inhalants, street opioids, prescription opioids, and other miscellaneous drugs. Response options include 0 = no, 1 = yes, but not in the past 3 months, and 2 = yes, in the past 3 months. At baseline and 3-month follow-up assessments, participants will complete the ASSIST in reference to past 3 months use.	Baseline (Pre-intervention) and Three-month Follow-up (3 months post first treatment session)
Change in problematic drug use.	Problematic drug use will be measured with the Drug Use Disorders Identification Test (DUDIT). The DUDIT is a self-report instrument composed of 11 items identifying problems related to substance use. Scoring of the DUDIT is two-fold: items 1 to 9 are scored on a five-point Likert scale, while items 10 and 11 are scored on a three-point scale. The overall score is calculated by summing the scores on all items. Higher scores represent greater problematic drug use. At baseline and 3-month follow-up assessments, participants will complete the DUDIT in reference to past 3 months use.	Baseline (Pre-intervention) and Three-month Follow-up (3 months post first treatment session)
Change in heavy drinking presence	Heavy drinking presence will be measured by asking if participants had 4 of more drinks if assigned female at birth or intersex OR 5 or more drinks if assigned male at birth in the past 3 months. At baseline and 3-month follow-up assessments, participants will answer the question about heavy drinking presence in reference to past 3 months.	Baseline (Pre-intervention) and Three-month Follow-up (3 months post first treatment session)
Change in alexithymia	Alexithymia will be measured with the Perth Alexithymia Questionnaire (4-item negative-difficulty identifying feelings subscale and 4-item negative-difficulty describing feelings subscale). The Perth Alexithymia Questionnaire (PAQ) is a 24-item self-report measure of alexithymia answered on a 7-point Likert scale (1 = strongly disagree, 7 = strongly agree). Subscales can be summed to derive an overall alexithymia total score, with higher scores indicative of higher levels of alexithymia.	Baseline (Pre-intervention), Immediate Post-intervention (1 week post first treatment session), and Three-month Follow-up (3 months post first treatment session)
Change in dissociation	Dissociation will be measured with the Brief Dissociative Experiences Scale (DES-B) - Modified, which was recently Modified for DSM-5. The DES-B is an eight items scale that measures the phenomena of dissociative experience over the past week, not necessarily pathological dissociation. Response options range from 0 to 4, with 0 indicating not at all, and 4 more than once a day. At baseline, 1-week, and 3-month follow-up assessments, participants will complete the DES-B in reference to the past week.	Baseline (Pre-intervention), Immediate Post-intervention (1 week post first treatment session), and Three-month Follow-up (3 months post first treatment session)
Change in physical health symptoms	The investigators will also assess physical health symptoms using the Patient Health Questionnaire - 15 (PHQ-15), a self-administered somatic symptoms subscale derived from the full PHQ. Participants are asked to rate the severity of their symptoms during the previous 4 weeks on a 3-point scale as either 0 ("not bothered at all"), 1 ("bothered a little") or 2 ("bothered a lot"). Total symptom severity score ranged from 0 to 30. At baseline and 3-month follow-up assessments, participants will answer the questions about physical health symptoms in reference to the past month.	Baseline (Pre-intervention) and Three-month Follow-up (3 months post first treatment session)
Change in general health perceptions	Physical health symptoms will be assessed using the first item of the Short-Form Health Survey (SF-12). Response options are on a 5-point Likert-scale with higher scores indicating worse general health perceptions. Scores range from Excellent (0) to Poor (4).	Baseline (Pre-intervention) and Three-month Follow-up (3 months post first treatment session)
