Data Analysis/ Study Questions1. Is there a significant positive change on the overall LPP score for those parent participants whose intervention outcome was described as positive by the therapist? (Wilcoxon signed ranks test). 2. Is there a significant positive change on the LPP Items most closely related to the established goals for those parent participants whose intervention outcome was described as positive by the therapist?(Wilcoxon signed ranks test).3. Do levels of sensory processing as measured by the Infant Toddler Sensory Profile (ITSP) correlate with parent participation as measured by LPP?4. Do levels of maladaptive behavior, as measured by the Child Behavior Checklist (CBCL) correlate to levels of parent participation as measured by the LPP?5. Does the pattern of sensory presentations as measured by the ITSP correlate with maladaptive behaviors as measured by CBCL?Study data (demographics and data) from LPP completion (pretest only for those in the longitudinal study) will be added to data from previous studies (n= 162 + 60plus) for confirmatory principle component analysis (oblique rotation).
