Trial Outcomes & Findings for Supporting Parents Program: Intervention for Families in CPS (NCT NCT01332851)

DCFS volunteer scanned WA State DSHS database monthly (January 2011- January 2014); created list of possibly eligible families (N=1070). Potential participants contacted (n=556; n=514 unable to be contacted), permission received to forward their contact information to the study (n=251; n=172 ineligible, n=133 declined).

4 participants were not randomized (2 already had the study intervention, 1 refused to sign the HIPAA agreement, and 1 was not located). 19 additional caregivers were enrolled post randomization when the study parent lost custody of their child. They were not "randomized" to a condition, but they were consented to participate and supplied data.

Supporting Parents Program: Intervention for Families in CPS

Official child welfare administrative records indicating whether child was removed from the birth parent home within one year of parent completing intervention (or one year after estimated date intervention would have been completed, for parents who did not complete). Data were analyzed with a survival model that predicted hazard of being removed from the birth parent home.

Parent sensitivity was measured at all four time points by a modified total score of the Nursing Child Assessment Teaching Scale (NCATS; Barnard, 1994), a videotaped interaction to assess caregiver sensitivity, stimulation of the child, and emotional responsiveness during interaction were scored. The scale was modified to exclude some items from the original measure that demonstrated low variability in other studies. A total score was based on 45 items, possible range 0 - 45. Items covered mutuality (e.g. contingency, gaze, and positive affect), caregiver verbal and nonverbal support of child, and sensitive instruction during the teaching task. Items were scored yes (1) or no (0), and yes scores were summed. Cronbach's alpha for the sensitivity scale ranged from .68 to .72. A single, blinded coder was trained to reliability by a certified NCATS instructor and passed regular reliability checks. Higher scores indicate greater parental sensitivity.

Secure base behavior was measured with the Toddler Attachment Sort-45 (TAS-45; Kirkland, Bimler, Drawneek, McKim, \& Schölmerich, 2004). The TAS-45 is based on 39 items from the Attachment Q-Sort (AQS; Waters, 1987), an attachment measure that has been extensively validated (van IJzendoorn, Vereijken, Bakermans-Kranenburg, \& Riksen-Walraven, 2004), plus six items tapping atypical affective communication. After home visits, research visitors sorted cards for 45 descriptive statements of child attachment behavior into five piles representing "most like" to "least like" the child. Item scores were standardized within individuals and then compared to a security profile to arrive at an security score. Higher value indicates greater secure base behavior. Because scores are based standardized item scores weighted by proximity to the secure profile, the possible range is large, difficult to determine, and not reported in the instrument manual. The observed range was from -.62 to +1.00.

Parenting stress was measured by scales selected from the Parenting Stress Index and the Parenting Stress Index-Short Form (PSI-3, PSI-SF; Abidin, 1995). The Parent-Child Dysfunctional Interaction Scale from the PSI-SF (11 items). Items were rated on 4-point scales (strongly agree to strongly disagree). Two items measuring parental educational attainment from the original parenting competence scale were omitted due to excessive missing data. Higher scores indicate greater parental stress associated with feelings of dysfunctional parent-child interactions (i.e., interactions are not reinforcing or satisfying). Alphas ranged from .71-.94 across time points. Possible range 11-55, observed range 12 to 43.

At baseline, 3-month post-intervention follow-up, and 6-month post-intervention follow-up, parenting stress was measured by scales selected from the Parenting Stress Index and the Parenting Stress Index-Short Form (PSI-3, PSI-SF; Abidin, 1995). The Parenting Competence Scale from the PSI-3 (11 items) was used. Items were rated on 4-point scales (strongly agree to strongly disagree). Two items measuring parental educational attainment from the original parenting competence scale were omitted due to excessive missing data. Higher scores indicate greater parental stress associated with feelings of incompetence. Alphas ranged from .71-.94 across time points. Possible range 11 - 55, observed range 11 - 39.

Child social-emotional competence (11 items; alphas = .69-.70) was measured by the Brief Infant Toddler Social and Emotional Assessment (BITSEA; Briggs-Gowan \& Carter, 2002). Possible range is 0 - 22. Parent report of child social-emotional competence in the last month were rated on a 3-point scale (not true/rarely; somewhat true/sometimes; very true/often). Higher scores indicate more competence.

Child behavior problems (31 items; alphas =.77-.79) were measured by parent report on the Brief Infant Toddler Social and Emotional Assessment (BITSEA; Briggs-Gowan \& Carter, 2002). Descriptions of positive and problematic social-emotional behaviors in the last month were rated on a 3-point scale (not true/rarely; somewhat true/sometimes; very true/often; items score 0, 1, 2 respectively). Higher score indicates more child behavior problems as noted by the parent. Possible range is 0 - 62.

Bayley Behavior Ratings (Bayley, 1993) to assess emotion regulation. At baseline and again at the 3-month follow-up, blinded research visitors rated the child's behavior during administration of a standardized developmental test using the Bayley Behavior Rating Scales (BRS; Bayley 1993). Seven items in the BRS comprise the emotion regulation scale and capture how well the child adapts to challenging stimuli and frustration (alphas = .79-.83). Possible range is 1 - 5, the mean of seven items scored from 1 to 5. Higher scores indicate better emotional regulation.

At baseline and again at the 3-month follow-up, blinded research visitors rated the child's behavior during administration of a standardized developmental test using the Bayley Behavior Rating Scales (BRS; Bayley 1993). Engagement/exploration consists of six items rated for exploratory behavior in the testing situation (alphas = .75-.76). The items were scored on a rage of 1 to 5, the mean of the six items was computed and the possible range is 1 to 5. Higher scores indicate more engagement.

Atypical, affective communication were measured with the Toddler Attachment Sort-45 (TAS-45; Kirkland, Bimler, Drawneek, McKim, \& Schölmerich, 2004). The TAS-45 is based on 39 items from the Attachment Q-Sort (AQS; Waters, 1987), an attachment measure that has been extensively validated (van IJzendoorn, Vereijken, Bakermans-Kranenburg, \& Riksen-Walraven, 2004), plus six additional items tapping atypical, affective communication. Immediately after research home visits, the research visitors sorted cards for 45 descriptive statements of child attachment behavior into five piles representing "most like" to "least like" the child. Item scores were standardized within individuals and then scaled with weights for the D hotspot. Because scores are based on standardized item scores, the possible range is large, difficult to determine, and not reported in the instrument manual. Observed range -1.511 to + .860.

Coding Interactive Behavior-Child \& Parent Outcomes (CIB; Feldman, 1998). Parent-child 10-minute free play interaction coded for child social engagement, child negative affect, and dyadic reciprocity; parental sensitivity and reciprocity, parental intrusiveness, and parental withdrawal. NOTE: THIS MEASURE WAS COLLECTED AND CODED. HOWEVER, THE MEASURE SUFFERED FROM LOW INTERNAL CONSISTENCY AND RESTRICTED VARIATION (I.E., A LARGE PORTION OF SCORES WERE NEAR THE MAXIMUM POSSIBLE VALUE). WE DID COMPARE SCORES BY CONDITION AND ALL COMPARISONS INDICATED NONSIGNIFICANT DIFFERENCES BETWEEN PFR AND R\&R CONDITIONS. DUE TO LOW RELIABILITY AND RESTRICTED VARIATION OF THE MEASURE, IT WAS DECIDED TO NOT REPORT THESE RESULTS.

Caregiving Helplessness Questionnaire (CHQ; George, Coulson, Majany, \& Soloman, 1995) subscales: parent-child frightened and parent helplessness. NOTE: THIS MEASURE WAS COLLECTED AND COMPARISONS BETWEEN PFR AND R\&R INDICATED NONSIGNIFICANT DIFFERENCES. DUE TO LOW INTERNAL CONSISTENCY OF THE MEASURE, IT WAS DECIDED TO NOT REPORT PFR VS. R\&R COMPARISONS FOR THIS MEASURE.

"About My Baby": three open-ended questions; coded to assess "mindfulness" representations of the child's mental life. NOTE: THIS MEASURE WAS DROPPED FROM THE STUDY. OPEN-ENDED QUESTIONS WERE INCLUDED IN INITIAL ASSESSMENTS. ANSWERS WERE REVIEWED BY THE RESEARCH TEAM, AND IT WAS DECIDED THAT RELIABLE AND VALID CODING WAS NOT POSSIBLE.

Parent Opinion Questionnaire (POQ; Azar et al., 1984): questionnaire to assess unrealistic parental expectations of child behavior in the areas of self-care, help and affection to parents, leaving children alone, proper feelings and behavior punishment, and family responsibility. NOTE: THIS MEASURE WAS COLLECTED. RESPONDENTS WERE OFFENDED BY SOME QUESTIONS, WE REDUCED THE NUMBER OF QUESTIONS AT BASELINE AND COLLECTED THE FULL INSTRUMENT AT FOLLOW UP 1. HOWEVER, IT SHOWED LIMITED VARIABILITY. COMPARISONS BETWEEN PFR AND R\&R CONDITIONS INDICATED NONSIGNIFICANT DIFFERENCES. DUE TO THE LIMITED VARIABILITY, IT WAS DECIDED NOT TO REPORT THESE RESULTS.
