Growing evidence demonstrates that secure attachment in childhood predicts children's healthy social, biological, and behavioral functioning, whereas insecure attachment predicts behavior problems and physiological dysregulation; thus, efforts to foster secure attachment are crucial for promoting the healthy development of children and families. This proposal describes a randomized controlled trial (RCT) of an innovative intervention program that can be widely implemented designed to foster children's secure attachment, promote healthy physiological regulation, and reduce the risk for behavior problems: The Circle of Security ® Parenting (COS-P) intervention. To this end, investigators will conduct an RCT with 249 parent-child dyads enrolled or are eligible but not yet enrolled in two diverse Early Head Start (EHS) programs.

COS-P is an attachment-based, home visiting intervention intended to supporting parents in serving as "a secure base" from which their children can explore the world, and to which their children can return in times of distress (Bowlby, 1988). Such secure base parenting increases the likelihood of children's secure attachment. COS-P also targets parental responses to children's expression of their needs (e.g., crying), and is designed to help parents understand the ways in which their own (parental) dysregulated emotional, physiological, and behavioral responses to children's emotions and behaviors can limit their responsiveness to their children's attachment needs.
Little Talks is an early literacy home visiting intervention developed for low-income, racial and ethnic minority infants and toddlers, and has been tested in Early Head Start contexts (Manz et al., 2016; Manz et al. 2017). Little Talks uses book sharing to promote early literacy and has been adapted in both English and Spanish. The intervention utilizes modular treatments during home visits, teaching parents how to facilitate language interactions with their children through book sharing. Age appropriate books are given to parents to share with their children during the intervention.

Cortisol Stress Reactivity and Recovery #1
Cortisol stress reactivity and recovery will be assessed (following previous studies; e.g., Luijk et al., 2010) using the Strange Situation Procedure (SSP) as the stressor. Salivary samples will be collected (using a 125mm polymer swab) at baseline (pre-task), 10-, 20-, 30-, and 40-minutes post peak SSP stressor (i.e., end of separation 2), then frozen in tubes. Radioimmunoassay analysis will be done in duplicate, with the mean used as the final measure (in ug/dl). Labs will begin in the afternoon (between 1-4pm) to reduce potential diurnal effects. Multiple studies (e.g., Bernard \& Dozier, 2010; Thompson et al., 2015) demonstrated a lack of diurnal influence in infant cortisol studies, thus time of day will not be controlled. Cortisol may fluctuate with sleep/wake patterns and eating (Gunnar \& Herrera, 2013), so investigators will control for time of last waking and eating.

Adverse Childhood Experiences Questionnaire (ACE-Q)
The Adverse Childhood Experience Questionnaire (ACE-Q; Felitti et al., 1998) is a brief rating scale that measures the number of adverse childhood experiences that occurred in the first 18 years of life. The ACE-Q has 9 yes/no items that count the number of adverse childhood experiences participants experienced in the first 18 years of their life. A sample item is "Did a parent or other adult in the household often swear at you, insult you, put you down, or humiliate you? OR act in a way that made you afraid that you might be physically hurt?" Participants indicate yes or no for each question, and if the answer is yes, then a score of 1 is entered for that item. The number of ACEs is the total number of questions for which the answer was yes. To avoid asking younger participants about experiences of physical or sexual abuse, this questionnaire will only be given to participants over 20 years of age.

Role Overload #3
Following the recommendations of Thiagarajan et al. (2006), Reilly's (1982) 13-item Role Overload Scale will be adapted into a 6-item unidimensional scale assessing parents' feelings of being overwhelmed with parenting duties, juggling multiple obligations, and lacking time to rest or pursue desired activities (e.g., "I cannot ever seem to catch up"). Parents' scores indicating how often they agree with the corresponding statements, using a 7-point scale which ranges from 1 = Never to 7 = Always, will be averaged.
Time frame: 6-month follow-up
My Exposure to Violence
Witnessing community violence and violent victimization will be assessed using two subscales (victimization and witnessing) of the My Exposure to Violence (MyETV; Selner-O'Hagan et al., 1998). This is a 25-item instrument that was designed to measure participants' exposure to violence in the past year. The MyETV asks participants about witnessed as well as personally experienced violence, yielding three subscales (of which investigators will use two). The three subscales are witnessing violence, violent victimization, and total exposure. Frequency of exposure is measured on a 4-point scale (once, 2 or 3 times, 4 to 10 times, more than 10 times). To avoid asking questions about childhood physical or sexual abuse, this questionnaire will only be given to participants over 20 years of age.

Center for Epidemiologic Studies Depression Scale (CES-D) #1
Parental depressive symptoms will be assessed with the CES-D (Radloff, 1977). This 20-item self-report measure (Radloff, 1977) taps the frequency with which respondents experienced depressive symptoms over the past week. Responses are given on a 4-point scale, with 0 indicating that the symptom was rarely or never felt, and 3 indicating that it was experienced most or all of the time.
Time frame: Baseline
Center for Epidemiologic Studies Depression Scale (CES-D) #2
Parental depressive symptoms will be assessed with the CES-D (Radloff, 1977). This 20-item self-report measure (Radloff, 1977) taps the frequency with which respondents experienced depressive symptoms over the past week. Responses are given on a 4-point scale, with 0 indicating that the symptom was rarely or never felt, and 3 indicating that it was experienced most or all of the time.
Time frame: Immediately post-intervention
Center for Epidemiologic Studies Depression Scale (CES-D) #3

Child Behavior Questionnaire
Parents will complete the age appropriate version of the Child Behavior Questionnaires designed by Rothbart \& colleagues (e.g., Putnam \& Rothbart, 2006). This questionnaire assesses child temperamental reactivity and child fearful temperament.
Time frame: Baseline
Stranger Approach Lab-TAB Task to assess child temperament
Raters will observe child temperament during the 'Stranger Approach' Lab-TAB task (Goldsmith \& Rothbart, 1999), a task designed to elicit fearfulness by having an adult stranger approach and stare at the child in a standardized fashion. The elements of novelty and intrusiveness should elicit various degrees of fearful distress and avoidance. This task lasts approximately 1-2 minutes.
Time frame: Baseline
Behind Barrier Lab-TAB Task to assess child temperament
Raters will observe child temperament during the 'Behind Barrier' Lab-TAB task (Goldsmith \& Rothbart, 1999), a task designed to elicit frustration and anger by placing a toy, with which the child has been playing, behind a barrier. Anger is coded as verbal and physical action against the barrier or persons present. This task lasts approximately 3 minutes.
Time frame: Baseline
Jar Lab-TAB Task to assess child temperament
Raters will observe child temperament during the 'Jar' Lab-TAB task (Goldsmith \& Rothbart, 1999), a task designed to elicit frustration and anger by placing an attractive snack (e.g. rainbow goldfish), in a plastic jar. This action is representative of the type of frustration a child typically encounters when exploration or play is blocked. Anger is coded as verbal and physical action against the jar or persons present. This task lasts approximately 1-2 minutes.
Time frame: Baseline
Spider Lab-TAB Task to assess child temperament
Raters will observe child temperament during the 'Spider' Lab-TAB task (Goldsmith \& Rothbart, 1999), a task designed to elicit fearfulness by having a toy spider unexpectedly approach the child. The elements of novelty, uncertainty and intrusiveness, as well as a possible fear of animals, should elicit varying degrees of fear. This task lasts approximately 2-3 minutes.
