Participant satisfaction as measured by the Client Satisfaction Inventory Short-Form (McMurtry & Hudson, 2000). This measurement is a 9-item self-report scale that assesses the satisfaction of the participant with the effects of the treatments. Participants are asked to rate the way they feel about the services they received on a 7-point Likert scale, ranging from 1 ("none of the time") to 7 ("all of the time"). The total scores range between 0 and 100 (for scoring algorithm, see McMurty & Hudson, 2000), with higher scores indicating more satisfaction. Data is collected for the intervention group at post-assessment only.

Self-reported confirmation of pregnancy. Data collected at baseline, pre-assessment, mid-assessment, post-assessment, and follow-up.

Individual changes in anxiety as measured by the Beck Anxiety Inventory. The Beck Anxiety Inventory is a 21-item self-report measure used to assess somatic or panic-related anxiety symptoms. Individuals are asked to rate their symptoms of anxiety over the past week on a 4-point Likert scale from 0 ("not at all") to 3 ("severely; I could barely stand it"). A total score is calculated by summing all items. Scores range from 0 (no anxiety severity) to 63 (severe anxiety severity). Data collected throughout study (baseline, pre-assessment, mid-assessment, post-assessment, and follow-up) as well as at the beginning of each intervention module.

Between group changes in anxiety as measured by Beck Anxiety Inventory (Beck, Steer, Beck, & Newman, 1993). The Beck Anxiety Inventory is a 21-item self-report measure used to assess somatic or panic-related anxiety symptoms. Individuals are asked to rate their symptoms of anxiety over the past week on a 4-point Likert scale from 0 ("not at all") to 3 ("severely; I could barely stand it"). A total score is calculated by summing all items. Scores range from 0 (no anxiety severity) to 63 (severe anxiety severity). Data collected throughout study (baseline, pre-assessment, mid-assessment, post-assessment, and follow-up) as well as at the beginning of each intervention module.

Individual changes in depression as measured by the Beck Depression Inventory - 2nd Edition. The Beck Depression Inventory - 2nd Edition is a 21-item self-report measure used to assess cognitive, affective, and physical depressive symptoms. Questions include content such as sadness, guilt, disappointment, and loss of energy. Participants are asked to rate each item on a 4-point Likert scale from 0 (not endorsed) to 3 (endorsed at maximum severity). A total score is calculated by summing all items. Scores range from 0 (no depressive symptoms) to 63 (severe depressive symptoms). Data collected at baseline, pre-assessment, mid-assessment, post-assessment and follow-up).

Between group changes in depression as measured by the Beck Depression Inventory - 2nd Edition (Beck, Steer, Ball, & Ranieri, 1996). The Beck Depression Inventory - 2nd Edition is a 21-item self-report measure used to assess cognitive, affective, and physical depressive symptoms. Questions include content such as sadness, guilt, disappointment, and loss of energy. Participants are asked to rate each item on a 4-point Likert scale from 0 (not endorsed) to 3 (endorsed at maximum severity). A total score is calculated by summing all items. Scores range from 0 (no depressive symptoms) to 63 (severe depressive symptoms). Data collected at baseline, pre-assessment, mid-assessment, post-assessment and follow-up).

Between group changes in stress as measured by Perceived Stress Scale. The Perceived Stress Scale is a 10-item questionnaire measuring the present level of self-rated stress in the last month. Items were designed to assess how unpredictable, uncontrollable, and overloaded respondents find their lives. Higher scores indicate more distress. Participants are asked to rate each item on a 5-point Likert scale from 0 ("never") to 4 ("very often"). Scores range from 0 to 40 where higher scores indicate greater perceived stress (for scoring algorithm see Cohen, 1988; Cohen, Kamarck, & Mermelstein, 1983).

Between group changes in mindfulness as measured by the Five-Factor Mindfulness Questionnaire (FFMQ; Baer, Smith, Hopkins, Krietemeyer, & Toney, 2006). The FFMQ is a 39-item self-report measure used to assess a trait-like tendency to be mindful in daily life. It has five subscales (i.e., observe, describe, awareness, non-judgmental, and non-reactive). Each question on the FFMQ is rated on a 5-point Likert scale ranging from 1 ("never or very rarely true") to 5 ("very often or always true"). Total score (adding subscale scores) ranges from 39 to 195 with higher scores indicating greater mindfulness (for scoring algorithm see Baer, Smith, Hopkins, Krietemeyer, & Toney, 2006). Data collected at baseline, mid-assessment, and post-assessment.

Between group changes in fertility related distress as measured by The Fertility Problem Inventory. The Fertility Problem Inventory is a 46-item questionnaire that measures domains (Social Concern, Sexual Concern, Relationship Concern, Need for Parenthood, and Rejection of Child-Free Lifestyle) considered important in understanding perceived infertility related stress as well as an overall global index of infertility-related stress (composite score of the all domains). The overall score ranges from 46 to 276. For each of the scales, higher scores indicate more fertility related distress (for a scoring algorithm see Newton, Sherrard, & Glavac, 1999). Data collected at baseline, post-assessment, and follow-up.

Between group changes in emotion regulation as measured by the Difficulties in Emotional Regulation Scale (DERS; Gratz & Roemer, 2004). The DERS is a 36-item self-report questionnaire measuring problems with emotional regulation based on responses indicating impairment in six dimensions (Goals, Impulse, Awareness, Nonacceptance, Strategy, and Clarity) and a total score (sum of all subscales). Total score ranges from 36 to 180. For each of the scales, higher scores indicate greater difficulties with emotional regulation in each of the domains (for scoring algorithm see Gratz & Roemer, 2004). Data collected at baseline and post-assessment.

Between group changes in emotion regulation as measured by the Dyadic Adjustment Scale (Spanier, 1976). The Dyadic Adjustment Scale is a 32-item questionnaire assessing relationship difficulty in four domains (Consensus, Satisfaction, Affective Expression, and Cohesion) and a total score. The total score ranges form 0 and 151. Greater scores indicate greater marital satisfaction (for scoring algorithm see, Spanier, 1976). Data collected at baseline and post-assessment.
