The State-Trait Anxiety Inventory (STAI) is a measure of trait and state anxiety. STAI contains 20 items for assessing trait anxiety and 20 items for state anxiety. State anxiety items include: "I am tense; I am worried" and "I feel calm; I feel secure." Trait anxiety items include: "I worry too much over something that really doesn't matter" and "I am content; I am a steady person." All items are rated on a 4-point scale (e.g., from "Almost Never" to "Almost Always"). Scores may range from 20 to 80 with higher scores indicating greater state anxiety.

The OCI-R, a shortened version of the Obsessive-Compulsive Inventory, assesses symptoms of Obsessive Compulsive Disorder (OCD). The measure consists of 18 items (e.g. "I frequently have get nasty thoughts and have difficulty in getting rid of them"). On a five point scale, respondents rate how distressed or bothered they have been in the past month by the symptom described, with responses ranging from "Not at all" to "Extremely." Scores are generated by adding the item scores. Total possible score range 0 to 72, scores at or above 21 indicating the likely presence of OCD.

Self-reported changes in the levels of pain as measured by the PROMIS Pain Interference Scale. PROMIS-PI scores provided substantial information across levels of pain. The scale for adults in the general population is available in both a 41 item long-form computer adaptive version and a 4 item short form which will be used in this study. Each item is based on experiences in the last seven days before administering the questionnaire. It uses a 5-point rating scale (1-"not at all" to 5-"very much"), with higher scores indicating more pain interference.

The PROMIS-Sleep Disturbance (PROMIS-SD) is used to asses self-reported perceptions of sleep quality, sleep depth and restoration associated with sleep. The full PROMIS- SD includes 27 with each item is based on a 7-day recall period and assessed on a 5 level Likert-type scale. The 8 item short form will be used in this study, in which responses are scored 1 to 5 for each item. A higher score on 5 of the 8 items reflects a worse outcome, whereas a higher score on 3 items reflects an improved outcome; therefore, the directionality of the 8 item scores are first synchronized prior to calculation of the total raw score. To find the total raw score for a short form with all questions answered, sum the values of the response to each question. For example, for the adult 8-item form, the lowest possible raw score is 8; the highest possible raw score is 40. PROMIS scores are presented as T-scores. Higher T-scores represent more of the concept being measured (sleep disturbance).

The Patient Reported Outcomes Measurement Information System (PROMIS)Sleep Related Impairment bank is a 16 item computer adaptive test bank that focuses on perceptions of alertness, sleepiness, and tiredness during usual waking hours. Each item is based on a seven day recall period and assessed on a 5 score for a short form with all questions answered, sum the values of the response to each question. For example, for the adult 8-item form, the lowest possible raw score is 8; the highest possible raw score is 40. To find the total raw score for a short form with all questions answered, sum the values of the response to each question. For example, for the 8-item form, the lowest possible raw score is 8; the highest possible raw score is 40. PROMIS scores are presented as T-scores. Higher T-scores represent more of the concept being measured (sleep related impairment).

The Patient-Reported Outcomes Measurement Information System (PROMIS) Self-Efficacy for Managing Emotions is designed for adults with at least 1 chronic health condition. The items are not focused on one specific condition but are designed to universally measure one's current level of confidence to manage emotional symptoms such as anxiety, depression, helplessness, discouragement, frustration, disappointment and anger. The instrument has a 25 item computer adaptive test form and 2 short forms: an 8 item and a 4 item. Each question has 5 response options ranging in value from 1 to 5. To find the total raw score for a short form with all questions answered, sum the values of the response to each question. For example, for the 8-item form, the lowest possible raw score is 8; the highest possible raw score is 40. PROMIS scores are presented as T-scores. Higher T-scores represent more of the concept being measured (self efficacy).

The Patient Health Questionnaire-2 (PHQ-2) is a 2-item Brief Depression Screening Instrument. It inquires about the frequency of depressed mood and anhedonia over the past 2 weeks, scoring each as 0 ("not at all") to 3 ("nearly every day"). It ranges from 0-6, where higher score means higher depressive symptoms.

The Perinatal Post-Traumatic Stress Disorder (PTSD) Questionnaire (PPQ) is a 14-item measure assessing post-traumatic symptoms related to the childbirth experience, including intrusiveness or re-experiencing, avoidance behaviors and hyperarousal or numbing of responsiveness. The PPQ also contains one item pertaining to feelings of guilt. Response options were modified from the original dichotomous scale to a five-level likert scale (scored 0 to 4). Mothers were instructed to provide responses that reflected their experience during the targeted time frame (4 to18 months postpartum). The total possible score on the modified PPQ ranged from 0 to 56. A score of 19 or higher on the PPQ indicates clinically significant distress that merits referral of the mother to a mental health care professional.

The GAD-7 is a self-reported questionnaire for screening and measurement of severity of generalized anxiety disorder (GAD). This questionnaire has 7 items which measure the severity of various signs of GAD over the past 2 weeks according to the reported response categories with assigned points - "not at all" (0 points), "several days" (1 point), "more than half the days" (2 points), and "nearly every day" (3 points). Total score=sum of all 7 items; ranges from 0 to 21; Higher score=greater level of anxiety).

The modified version of the Pregnancy-Unique Quantification of Emesis and Nausea (modified-PUQE) provides global nausea and vomiting of Pregnancy (NVP) severity index. The modified-PUQE is a three-item questionnaire with each item having a 5 level Likert type scale (1 to 5, increasing in severity). The total score is the sum of replies to the 3 items and rated from 3 (no symptoms) to 15 (most severe). A score of 7 to 12 indicates moderate NVP and a score greater than 13 indicates severe NVP.

The Infant Feeding Intentions (IFI) scale was developed to meet the need in breastfeeding behavior studies for quantitative measure of maternal breastfeeding intentions. This is a 5 item scale that probes strength of intentions to initiate breastfeeding. Total score ranges from 0 to 16. Higher score means higher intention to breastfeed exclusively.

The questions used to assess breastfeeding behavior immediately post-delivery are adapted from Infant Feeding Practices Study II (IFPS II). The Neonatal Questionnaire was sent to the mother when her infant is approximately 3 weeks old. This questionnaire examined factors that commonly occur near the time of the birth and that affect infant feeding choices. This study will use 3 of their face valid questions to assess if the new mother has tried to breastfeed, if so, how long it took for her milk to produce, and if she is still breastfeeding.

The questions used to assess longitudinal breastfeeding behavior post-delivery are also adapted from Infant Feeding Practices Study II (IFPS II). The Postnatal Questionnaires consist of various combinations of 8 modules that were mailed to the mother approximately monthly from the time her infant is 2 months through 12 months of age. A 4 question subset of the breastfeeding questionnaire will be used in this study to evaluate continued breastfeeding practices and reasons to begin using formula or to stop breastfeeding.
