Conditions

Anxiety, Depressive Symptoms

Brief summary

The investigators are evaluating the acceptability and effectiveness of brief online wellness modules. Participants will be randomly assigned to the intervention condition, an active control condition, or a wait-list control condition. The investigators are using a factorial design, such that each participant in the intervention condition will be randomly assigned to receive three of four wellness modules. The investigators will analyze the intervention's effectiveness as a universal intervention (using the full sample) and a targeted intervention (using the subset of the sample that reported elevated depressive symptoms or anxiety symptoms at baseline).

Interventions

OTHERCommon Elements Toolbox- Adult version (COMET-A)

COMET includes four different modules that teach participants exercises designed to improve mental health and well-being. Participants are asked to complete exercises focused on behavioral activation, cognitive restructuring, gratitude and self-compassion. At the end of the intervention, participants are sent templates that they can you to complete the exercises on, and are encouraged to continue practicing their exercises in their daily life.

OTHERSelf-awareness Control

A control condition in which participants learn about self-awareness through writing about memories, writing a short argumentative essay, and noticing objects in their surroundings.

Design outcomes

Primary

MeasureTime frameDescription
Change in Patient Health Questionnaire-9 (PHQ-9)Up to 12 weeks post-interventionDepression questionnaire. Scores range from 0 to 27. Lower scores indicate less depression.
Change in Generalized Anxiety Disorder Screener-7 (GAD-7)Up to 12 weeks post-interventionAnxiety questionnaire. Total scores range from 0-21. Lower scores indicate less anxiety.
Change in Short Warwick-Edinburgh Mental Well-being Scale (SWEMWBS)Up to 12 weeks post-interventionSubjective Well-being questionnaire. Total scores range from 7 to 35. Higher values indicate higher well-being scores.
Ratings of Acceptability of Intervention Measure (AIM)Immediately after the interventionQuestionnaire measuring the acceptability of an intervention. Acceptability refers to the perception that a given treatment is agreeable or satisfactory. The total score ranges from 4 to 20. Higher scores indicate higher acceptability ratings.
Mechanism QuestionsUp to 12 weeks post-interventionParticipants answered questions relating to each module's mechanism of change on a 7-point Likert Scale, from strongly disagree to strongly agree. Specifically, we asked participants: * How capable they feel about managing negative thoughts * If they will intentionally spend time doing activities they enjoy * If they will notice and appreciate good things * If they will be able to treat themselves with empathy and compassion
Ability to Cope with COVID-19Up to 12 weeks post-intervention2 questions related to their ability to cope with stressors over the upcoming weeks (including challenges relating to COVID-19). Participants answered these questions on a 7-point Likert Scale, from strongly disagree to strongly agree. Specifically, we asked participants: * if they will be able to handle lifestyle changes due to the coronavirus, * if the pandemic will have an extremely negative impact on their life.
Secondary ControlUp to 12 weeks post-interventionWe asked participants three items to assess secondary control (Weisz et al., 2010). The items are scored on a 4-point Likert scale, ranging from 0 (Very false) to 3 (Very true). The three items are: * When something bad happens, I can find a way to think about it that makes me feel better. * After a really hard day, I can make myself feel better by remembering some good things that happened. * When bad things happen to me that I can't control, there are lots of things I can do to feel better. Higher scores will indicate greater secondary control.
Perceived UtilityImmediately after the interventionParticipants were asked to rate three items relating to the perceived utility of each module. Specifically, we asked participants: * How helpful the module was * How engaging the module was * How much they will continue applying content from the module Higher scores will indicate greater perceived utility.
