In recent years, research in the area of intervention development has been shifting from the traditional fixed-intervention approach to "adaptive interventions," which allow greater individualization and adaptation of intervention options (i.e., intervention type and/or dosage) over time. Adaptive interventions are operationalized via a sequence…

Measures of agreement are used in a wide range of behavioral, biomedical, psychosocial, and health-care related research to assess reliability of diagnostic test, psychometric properties of instrument, fidelity of psychosocial intervention, and accuracy of proxy outcome. The concordance correlation coefficient (CCC) is a popular measure of…

The time-series process postulated is a more general form of the integrated moving average model than for which estimation and testing procedures were formerly available. (Author)

This study assessed the effects of a gluten-free diet over one year on learning patterns in three autistic children (ages 5 to 8) participating in an applied behavioral analysis program. Rates of learning for five behavioral targets 3 months, 6 months, 9 months, and 12 months after the start of the diet were compared using a within-subjects…

Incorporating statistical process control (SPC) methods into applied behavior analysis is discussed. It is claimed that SPC methods would likely reduce applied behavior analysts' intimate contacts with problems and would likely yield poor treatment and research decisions. Cases and data presented by Pfadt and Wheeler (1995) are cited as examples.…

Findings based on extended analyses of cognitive, familial, personality, and social-behavioral data from two previous research investigations are presented. Data for the main study, i.e., the present study, was collected principally by means of interviews. Findings of the principal study include the following: (1) Parental figures living in the…

Parents of children with autism face many challenges that arise from the practical, day-to-day issues of living with autism. The specific goals of this guide are to help parents: (1) Find information about autism; (2) Distinguish between research-based and non-research-based information; (3) Become savvy consumers of information by giving them the…
