Outcome Measurement

Sensational Kids Program Evaluation: September 2021 to April 2023


Sensational Kids’ program evaluation process began in late September of 2021, and since that time 226 clients have completed “pre-program” ratings, with 11 clients completing ratings across two services (i.e., occupational therapy and speech language therapy). Subsequent ratings are taken approximately 12 visits or three months after the previous ratings are collected. As of April 2023, across services and locations, 123 clients have follow-up data across 341 client-centered goals, suggesting the variety of needs being addressed at Sensational Kids.

Of those clients with follow-up ratings, 81% are reporting clinically meaningful changes in child performance related to individualized goals. A change score (the average difference in ratings across time) of about 2 points is considered to reflect clinically meaningful difference – that is, change that would be noticeable and impactful on daily life for a client (Cusick et al., 2007; Law, 2021). At Sensational Kids, the average change score for client ratings of goal performance is 3.05 points. These perceived gains are further supported by therapist reports of client changes over the course of treatment, which show a meaningful difference at an average of 3.06 points. Client satisfaction with child performance has also increased over the course of intervention at Sensational Kids, at an average of 3.21 points per client. Therapist satisfaction changed at an average of 3.15 points per client. These average ratings are particularly powerful considering they have remained about 3 points over time (see the table below for previous averages).

From this data, both client perception of performance on meaningful goals and their satisfaction in daily life have improved significantly over the course of intervention. Therefore, the COPM ratings document numerically the profound positive changes that therapists and clients know to be true about intervention at Sensational Kids.
