Generalized anxiety disorder (GAD) is characterized by excessive and uncontrollable worry and anxiety. When people with GAD worry, they tend to think about problems and feared situations in a vague way. Preliminary research suggests that writing about feared situations in a structured and detailed fashion may help with worry. In this experiment, the investigators are looking to improve the writing intervention. The investigators are testing the immediate and short-term effects of a new writing intervention.
Generalized anxiety disorder (GAD) is characterized by excessive and uncontrollable worry and anxiety about bad things that may happen in the future. When people with GAD worry, they tend to think about the situations they fear in a vague way. Preliminary research suggests that writing repeatedly about one's fears in a structured and detailed way may help worry. In the present experiment, the investigators are comparing three structured writing interventions and testing their immediate and short-term effects on worry, and worry-related features. Potential participants will be asked to complete a telephone screen. Those who meet eligibility criteria will be invited to the laboratory at Ryerson University. After completing pre-intervention outcome measures, participants will be randomly assigned to one of three writing interventions: (1) standard written exposure, (2) enhanced written exposure, or (3) neutral writing. All participants will write for 30 minutes on each of 4 days. The 4 sessions of writing will be spaced and will take place within a period of 2 weeks. Excessive worry will be assessed at pre-intervention, mid-intervention, post-intervention, 1-week follow-up and 1 month follow-up. With the exception of the Modified Behavioural Avoidance Test, which will only be assessed at pre-intervention and 1 month follow-up, all other outcomes will be assessed at pre-intervention, and at post-intervention, 1-week follow-up and 1 month follow-up. Additional assessments of Perceived Probability, Cost and Coping Questions will occur at each writing session. During the 2-week intervention period and the three days following the intervention period, all participants will also track their worry and mood twice per day. The present experiment will provide answers to important questions about the therapeutic potential of writing interventions for excessive worry.

Time frame: Administered before the intervention on day 1 (pre-intervention), post-intervention (3 days after writing session 4), 1-week follow-up, and 1-month follow-up.
Self-reported attitudes towards problems as measured by the Negative Problem Orientation Questionnaire
Self-report measure of attitudes towards problems. Twelve items are summed to create a total score. Total scores range from 12 to 60, with higher scores indicating greater negative attitudes towards problems.
Time frame: Administered before the intervention on day 1 (pre-intervention), post-intervention (3 days after writing session 4), 1-week follow-up, and 1-month follow-up.

Self-reported fear of emotions as measured by the Affective Control Scale
Self-report measure of fear of emotions and attempts to control emotional experience. The scale contains 42 items divided into four subscales for distinct emotions: anxiety; depression; anger; positive emotion. Total scores range from 42 to 294; subscale scores range from 13 to 91, with higher scores indicating a greater fear of emotions.
Time frame: Administered before the intervention on day 1 (pre-intervention), post-intervention (3 days after writing session 4), 1-week follow-up, and 1-month follow-up.
Self-reported perceptions of shame as measured by the Shame-Aversive Reactions Questionnaire
Self-report measure of perception of shame as an undesirable and painful emotion. Fourteen items are summed to create a total score. Total scores range from 14 to 98, with higher scores indicating higher levels of shame aversion.
Time frame: Administered before the intervention on day 1 (pre-intervention), post-intervention (3 days after writing session 4), 1-week follow-up, and 1-month follow-up.
Self-reported maladaptive beliefs as measured by the Early Maladaptive Schema Questionnaire - Research version
Self-report measure of stable maladaptive beliefs. The scale contains 75 items divided into fifteen subscales for distinct maladaptive beliefs. Subscale scores range from 0 to 15, with higher scores indicating greater maladaptive beliefs.
Time frame: Administered before the intervention on day 1 (pre-intervention), post-intervention (3 days after writing session 4), 1-week follow-up, and 1-month follow-up.
Self-reported worry-related behaviours as measured by the Worry Behaviours Inventory
Self-report measure of worry-related behaviours. Ten items are summed to create a total score. Total scores range from 0 to 40, with higher scores indicating greater engagement in avoidant behaviors that are associated with worry.

Three distinct questions assess each of the following perceptions related to feared scenarios: 1) Probability, 2) Cost and 3) Coping. Perceived probability scores range from 0 to 6 with higher scores indicating greater perceived likelihood of worst fears coming true. Perceived costliness scores range from 0 to 6, with higher scores indicating greater perceived costliness of worst fears.
