Methods Used to Document Procedural Fidelity in School-Based Intervention Research

There has been a paucity of guidance on the methodological details needed for measuring and sampling the independent variable or actual intervention occurrences in research and practice. Furthermore, the planning and support necessary to document the independent variable in both circumstances may be considerable. The current study extends prior research by reviewing the methods used to document procedural fidelity in school-based intervention research with student participants published between 2005 and 2012 in journals known for publishing school-related intervention studies. Two hundred sixty-six articles met the inclusion criteria and the majority (70 %) used fidelity data in the analysis of intervention effectiveness. By systematically examining contributions of school-based intervention researchers across targeted variables as well as qualities of interventions and settings, suggestions can be made for (a) planning measurement of fidelity across phases of the intervention, (b) sampling fidelity occurrences, (c) preventing intervention failure by providing needed supports, and (d) responding to patterns of fidelity required for intervention and outcome measurement in both research and practice.     

Optimal or Typical Performance? The Impact of Instructional Set on the Behavioral Assessment of Parent-Child Interactions

The behavioral assessment of parent-child interactions is an important component of treatment planning and evaluation in many evidence-based parent training programs. However, numerous factors unrelated to the parent-child interaction may add error to the assessment. This study investigated the impact of task instructions on parents’ behaviors during the analogue parent-child interaction observation, the Dyadic Parent-Child Interaction Coding System (DPICS). Forty-eight mother-child dyads were randomly assigned to one of two conditions that differed on level of specificity of instructions. Significant differences were observed between groups, with parents who received specific instructions using more praises during the DPICS tasks. Specific instructions may shift parents’ behaviors toward optimal, rather than typical, interaction patterns and should be considered in the context of the assessment goals.     

Differences in Mothers' and Fathers' Readiness for Change in Parent Training

We investigated readiness for change (RFC), a construct that may contribute to the discrepancies between fathers' and mothers’ rates of participation in behavioral parent training. One hundred and twenty fathers and mothers of 2- to 7-year-old children with conduct problems completed standardized measures of RFC, child behavior problems, and parent stress as part of an intake to a parent-child interaction therapy clinic. Fathers reported less readiness for change, less confidence in their ability to make changes, were more defensive about the need to change, and saw treatment as less important than mothers. Results suggest that if clinicians match parent training interventions to mothers’ readiness, fathers may be left behind.     

The displacement field of a triangular dislocation loop–a correction with commentary

A correction is made to a previous coordinate-free formulation of the displacement field of a triangular dislocation loop by Barnett [Phil. Mag. A 51 383 (1985)]. Then, taking account of the correction, it is shown that the formulation reduces to that given by Hirth and Lothe [Theory of Dislocations, 2nd edn (Wiley, New York, 1982) p. 146.], which is restricted to a specially chosen coordinate system.     

Using Kindergarten Language,Dialect Variation,and Child Behavior to Predict Second Grade Reading Ability in African American Children

Previous research has demonstrated mixed findings pertaining to the risk conferred by variation from Mainstream American English (MAE) for African American children in our education system. Based on the research on language, behavior, and reading, the present study sought to examine the relative and combined contributions of culturally appropriate measures of risk status for disordered language and density of dialect use and classroom behavior (both competencies and problems) in predicting reading ability in a sample of typically developing African American elementary school students. 53 African American Kindergartner's (27 boys, 26 girls) were followed up with two years later in 2nd grade. In Kindergarten, children were screened for density of dialect use and risk of language impairment; teachers rated each child on behavior, social/emotional adjustment, and academic performance. Reading achievement was assessed in 2nd grade. Risk for disordered language development was the best predictor of 2nd grade reading, outperforming density of dialect use. Positive classroom behaviors were more predictive of reading than negative behaviors. This research supports the notion that language, classroom behavior, and reading achievement are intertwined in a complex manner and that when designing interventions for one, the entire system must be considered.     

Adult attachment style and stress as risk factors for early maternal sensitivity and negativity

The current study examined the individual and joint effects of self‐reported adult attachment style, psychological distress, and parenting stress on maternal caregiving behaviors at 6 and 12 months of child age. We proposed a diathesis‐stress model to examine the potential deleterious effects of stress for mothers with insecure adult attachment styles. Data from 137 mothers were gathered by the longitudinal Durham Child Health and Development Study. Mothers provided self‐reports using C. Hazan and P. Shaver's ( 1987 ) Adult Attachment Style measure, the Brief Symptom Inventory (L.R. Derogatis & P.M. Spencer, 1982 ), and the Parent Stress Inventory (R.R. Abidin, 1995 ); observations of parenting data were made from 10‐min free‐play interactions. Consistently avoidant mothers were less sensitive with their infants than were consistently secure mothers; however, this effect was limited to avoidant mothers who experienced elevated levels of psychological distress. Results suggest that the association between insecure adult attachment style and insensitive parenting behavior is moderated by concurrent psychosocial stress. Clinical implications for these findings are discussed.     

Father contributions to cortisol responses in infancy and toddlerhood

The current study is one of the first prospective examinations of longitudinal associations between observed father caregiving behaviors and child cortisol reactivity and regulation in response to emotional arousal. Observations of father and mother caregiving behaviors and child cortisol levels in response to challenges at 7 months and 24 months of child age were collected. Analyses were based on a subsample of children from the Family Life Project who lived with both their biological mothers and fathers and for whom there was at least partial cortisol data (7 months: n = 717; 24 months: n = 579). At the challenge conducted at 7 months of child age, 49.0% of the sample were girls; racial composition of the sample was 25.8% African American and 74.2% European American. At the challenge conducted at 24 months of child age 49.9% of the sample were girls; racial composition was 24.7% African American and 75.3% European American. We conducted analyses across assessment points simultaneously using mixed linear modeling for repeated measures data to test for differential effects of fathering across infancy and toddlerhood. Concurrent measures of father negativity were positively associated with greater increases in child cortisol levels in response to emotion challenge at 7 months (p = .01) and with higher overall levels of cortisol at 24 months (p < .001). However, there was no evidence that father caregiving during infancy independently predicted later cortisol activity during toddlerhood.     

Using a flipped spoon to decrease packing in children with feeding disorders

We evaluated the effects of redistribution and swallow facilitation with a flipped spoon on packing in 2 children with a feeding disorder. For both participants, packing decreased when we implemented the flipped spoon treatment package. Mechanisms responsible for behavior change and areas of future research are discussed.
